The global electronic component shortage may no longer be as volatile as in earlier years, but in 2026, it is far from resolved. Instead of worldwide chip shortages across all categories, today’s supply challenges are selective, SKU-specific, and heavily concentrated in automotive, EV, and industrial applications.

This shift has created a more complex sourcing environment. Components from major suppliers like Vishay, Onsemi, and Infineon remain available in many cases, but specific part families, process nodes, and automotive-qualified devices continue to carry elevated risk.

Below, we break down what’s happening in 2026, where the bottlenecks remain, and how to mitigate ongoing supply challenges.

What Is the Electronic Component Shortage in 2026?

The electronic component shortage in 2026 is characterized by selective, SKU-specific supply constraints rather than widespread global shortages. Automotive, EV, and industrial components - particularly power devices, automotive MCUs, and high-reliability passives-remain the most affected.

Vishay Components and Lead-Time Risks in the 2026 Electronic Component Shortage

Vishay components are foundational to nearly every electronics design, spanning both passive and discrete technologies. 

Which Vishay Components Are Most Affected by the Electronic Component Shortage?

·      Automotive-grade Vishay resistors

·      High-reliability Vishay capacitors

·      Vishay inductors used in automotive and industrial designs

·      Legacy Vishay semiconductors

·      Vishay diodes and Vishay bridge rectifier devices tied to mature nodes

Vishay Lead-Time and Supply Conditions

Entering 2026, Vishay’s overall supply position is more stable than during the peak shortage years. However, lead times remain longer than pre-pandemic norms, especially for automotive-grade and high-reliability components.

While constraints are not portfolio-wide, they can create serious bottlenecks when demand spikes unexpectedly.

Manufacturing and Portfolio Changes Affecting Vishay

Another factor influencing availability is Vishay’s ongoing plant consolidations and product line rationalization. While these moves improve long-term efficiency, they can create short-term SKU-level tightness.

This is especially visible in:

·      Certain Vishay diodes

·      Select Vishay bridge rectifier part numbers tied to legacy production lines

Vishay Supply Risk Summary for 2026

Vishay is not experiencing widespread stockouts, but passive and discrete components remain sensitive to demand surges. Automotive and industrial buyers should continue monitoring lead times closely, particularly for long-lifecycle designs.

Onsemi Allocation and Power Semiconductor Shortages in 2026

Onsemi remains a critical supplier for power and automotive electronics, with a portfolio centered on:

·      Power discretes and power modules

·      Silicon carbide (SiC) devices

·      Automotive image sensors and ADAS-related components

·      Power management ICs

These products are heavily tied to EV electrification and advanced driver assistance systems, two markets that continue to grow rapidly in 2026.

Why Is Onsemi Still on Allocation in 2026?

·      EV demand continues to exceed supply for power devices

·      Capacity is prioritized for long-term automotive contracts

·      Silicon carbide (SiC) production remains constrained

·      Regional allocation limits spot-market availability

Onsemi Components Most Affected by the Electronic Component Shortage

Despite broader market improvements, several Onsemi product families remain constrained:

·      SiC MOSFETs and diodes used in EV traction inverters and onboard chargers

·      Automotive image sensors supporting ADAS platforms

·      Power management ICs for automotive and industrial designs

Onsemi Supply Outlook Summary

In the current electronic component shortage environment, Onsemi remains one of the most allocation-sensitive suppliers, particularly for EV-related power devices. Buyers without long-term agreements face longer lead times and limited flexibility.

Infineon MOSFET and Automotive Semiconductor Shortages in 2026

Infineon plays a dominant role in automotive and industrial electronics, with key offerings that include:

·      Automotive microcontrollers

·      Power devices, including Infineon MOSFETs

·      Power management ICs

·      Sensors and automotive system ICs

Which Infineon Components Still Have Long Lead Times in 2026?

·      Automotive microcontrollers on mature nodes

·      Infineon MOSFETs for automotive and industrial use

·      Infineon SiC MOSFET devices for EV platforms

·      Infineon automotive MOSFET solutions requiring qualification

These parts are difficult to substitute due to qualification requirements and long design cycles.

Market Dynamics Impacting Infineon Supply in 2026

Infineon’s constraints are driven by several overlapping factors:

·      Uneven recovery across automotive and industrial end markets

·      Limited foundry expansion for legacy nodes

·      Continued allocation on select automotive-qualified parts

Infineon Supply Risk Summary

Infineon shortages are SKU-specific rather than portfolio-wide, but automotive MCUs and Infineon MOSFET families remain high-risk sourcing categories well into 2026.

Cross-Supplier Trends in the 2026 Electronic Component Shortage

Across Vishay, Onsemi, and Infineon, several common themes define the 2026 supply landscape:

·      Automotive and EV programs continue to consume disproportionate capacity

·      Long-lifecycle and mature-node components are more vulnerable than consumer devices

·      High-reliability passives and automotive-grade semiconductors face the longest lead times

In short, shortages have become more targeted and harder to predict.

Procurement and Sales Takeaways for 2026

Procurement teams should continue prioritizing risk mitigation for:

·      Automotive microcontrollers

·      SiC power devices

·      High-reliability Vishay components

Recommended Mitigation Strategies

To reduce exposure in 2026:

·      Qualify alternative parts early where possible

·      Build buffer stock for long-lead automotive SKUs

·      Work with sourcing partners that can access inventory beyond franchised channels
