Is there a pin-compatible replacement for YC124-JR-0722RL?

No, a pin-compatible replacement for YC124-JR-0722RL was not found in this review. The target is an 8-pin, 4-resistor array, while all suggested alternatives are 2-pin single resistors, which are physically incompatible.

What risks should I check before replacing YC124-JR-0722RL?

The main risk is the physical incompatibility. You must redesign your PCB to replace one 8-pin array with four 2-pin resistors. Additionally, for some alternatives, you must verify the power rating to ensure it meets or exceeds your application's requirements.

YC124-JR-0722RL Alternatives, Datasheet & Cross Reference | Yageo

YC124-JR-0722RL is a 4-element, 22-ohm resistor array in an 0804 package. While direct pin-compatible replacements must match this form factor, functional alternatives using individual resistors like AC0603FR-0722RL are available but require a board redesign.

AI replacement insight

Package riskhigh

Target is an 0804 8-pin array; alternatives are single 2-pin resistors in 0603/0402/0201 packages.

Electrical risklow

Resistance matches, and several candidates offer superior tolerance, TCR, and power rating.

Sourcing riskhigh

Switching from one array to four single resistors increases component count and placement operations.

Can it be replaced directly?

No, there are no direct, pin-compatible replacements for YC124-JR-0722RL among the candidates reviewed. The target is an 8-pin resistor array, while all candidates are 2-pin single resistors.

Best replacement path

If a board redesign is feasible, using four individual AEC-Q200 resistors like AC0603FR-0722RL provides a functional and parametric upgrade. Otherwise, search for other 4-element, 22-ohm resistor arrays in an 0804 package.

Main risk

The primary risk is the complete physical mismatch in package and pin count, which necessitates a full PCB layout redesign from one 8-pin component to four 2-pin components.

Recommended alternatives

Automotive-grade upgrade path with better tolerance and TCR, but requires board redesign.
