AC0201FR-0723K7L Equivalent & Substitute Parts

Part Overview

The AC0201FR-0723K7L is a 23.7 kOhms ±1% thick film chip resistor in 0201 package (0.60mm x 0.30mm) rated at 0.05W (1/20W). This component is manufactured by YAGEO and carries AEC-Q200 automotive qualification with moisture resistance. The part is currently in active production status with 1011 pieces available in inventory.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative qualified manufacturers while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

For new designs with automotive AEC-Q200 requirement: AC0201FR-0723K7L (primary) or CRCW020123K7FNED (alternative). Both parts carry full -55°C to 155°C operating range and ROHS3 compliance.

For applications with -55°C to 125°C operating range: RC0201FR-0723K7L or ERJ-1GNF2372C. Both are active production parts with high inventory availability and ROHS3 compliance.

For legacy designs or existing inventory: RK73H1HTTC2372F remains available with AEC-Q200 qualification and full temperature range, though marked as Not For New Designs.

All listed parts are ROHS3 compliant with MSL 1 rating and identical package dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm).

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-0723K7L replace AC0201FR-0723K7L in automotive applications?

A: RC0201FR-0723K7L is electrically equivalent but lacks AEC-Q200 automotive qualification. It is suitable only for non-automotive applications or where automotive qualification is not required. The operating temperature range is also limited to -55°C to 125°C versus -55°C to 155°C for the AC series.

Q: What is the difference between YAGEO AC and RC series resistors?

A: Both series use identical 0201 package and thick film composition with ±1% tolerance and ±200ppm/°C temperature coefficient. The AC series includes AEC-Q200 automotive qualification and extends to 155°C maximum operating temperature. The RC series is rated to 125°C and does not carry automotive qualification.

Q: Are all substitute parts physically interchangeable?

A: Yes. All listed parts share identical package dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), height (0.010" maximum / 0.26mm), and two-termination configuration. PCB footprints are directly compatible.

Q: Why is RK73H1HTTC2372F marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase and may face eventual discontinuation. Existing inventory remains available for legacy system support, but new designs should select from active production alternatives.

Q: Do all parts meet ROHS3 compliance?

A: Yes. All listed parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), ensuring compatibility with standard PCB assembly and storage requirements.

Q: Which substitute offers the highest inventory availability?

A: RC0201FR-0723K7L from YAGEO offers 84,292 pieces in stock, followed by ERJ-1GNF2372C from Panasonic with 71,288 pieces.
