A potential pin-compatible replacement with matching package, resistance, and tolerance.
Best Alternatives to RC-MT08W220JT
The RC-MT08W220JT is a standard 22Ω, 4-element resistor array in a compact 0402x4 package. While several functional alternatives exist, finding a direct pin-compatible replacement requires careful attention to package dimensions and power ratings.
AI replacement insight
Package riskmedium
Many alternatives are in a larger 0603x4 package, requiring a board redesign.
Electrical risklow
Electrical parameters are standard, but power rating for the best candidate needs verification.
Sourcing risklow
Multiple vendors produce similar resistor arrays, offering good sourcing options.
Can it be replaced directly?
Yes, WA04X220JTL from Walsin is a potential pin-to-pin replacement for RC-MT08W220JT, but requires datasheet verification.
Best replacement path
The most promising direct replacement is WA04X220JTL, which matches the package, pin count, and key electricals. However, its power rating must be verified from the datasheet.
Main risk
The primary risk is package incompatibility. Several functional alternatives exist but require a larger PCB footprint. For the pin-compatible option, data verification is essential.
