Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM3600F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications and package configuration as the main part. The primary distinction is active product status, making it suitable for new designs and ongoing production. However, moisture resistance is not explicitly specified for this variant, which may be a consideration for applications requiring enhanced environmental protection.

AC0201FR-07360RL (YAGEO)

This part is a direct cross-reference alternative from YAGEO. It matches all electrical parameters, package dimensions, and automotive compliance requirements of the main part. The AC0201FR-07360RL explicitly includes moisture-resistant construction and maintains active product status. This part is suitable for applications requiring equivalent performance with an alternative manufacturer source.

Both substitute parts are ROHS3 compliant, AEC-Q200 qualified, and rated for the full automotive temperature range (-55°C ~ 155°C). Selection between them should be based on supply chain requirements, preferred manufacturer relationships, and specific moisture resistance requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3600F be used as a direct replacement for RK73H1HTTC3600F?

A: Yes. Both parts share identical electrical specifications (360 Ohms ±1%, 0.05W), package type (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM3600F is active, while RK73H1HTTC3600F is not for new designs. Moisture resistance is not specified for RK73H1HTTCM3600F.

Q: Is AC0201FR-07360RL compatible with RK73H1HTTC3600F in automotive applications?

A: Yes. AC0201FR-07360RL meets all electrical and mechanical requirements for substitution. It provides 360 Ohms ±1% at 0.05W in the 0201 package, operates across -55°C ~ 155°C, carries AEC-Q200 qualification, and includes moisture-resistant construction. The part is manufactured by YAGEO and maintains active product status.

Q: What are the critical parameters for substitution?

A: Substitution requires matching: resistance value (360 Ohms), tolerance (±1%), power rating (0.05W), package type (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 qualification, and moisture resistance. All substitute parts listed meet these criteria.

Q: Does package type affect interchangeability?

A: No. All listed parts use the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). They are mechanically interchangeable on PCBs designed for 0201 components.

Q: Are there differences in moisture sensitivity between substitute parts?

A: All listed parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. However, RK73H1HTTC3600F and AC0201FR-07360RL explicitly specify moisture-resistant construction, while RK73H1HTTCM3600F does not include this specification.

Q: Can these parts be used interchangeably in new designs?

A: RK73H1HTTCM3600F and AC0201FR-07360RL both carry active product status and are suitable for new designs. RK73H1HTTC3600F is designated "Not For New Designs" and should be used only for legacy design support or production continuity.
