Parameter Comparison

Engineering Selection Recommendations

RK73H1HTTCM97R6F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics. It maintains all critical electrical and mechanical parameters identical to the RK73H1HTTC97R6F. The primary distinction is Active product status, indicating ongoing manufacturing support and availability. This part is suitable for direct replacement in production environments where supply continuity is required. Note that moisture resistance is not explicitly specified for this variant, though it shares the same series designation.

AC0201FR-0797R6L (YAGEO): This YAGEO part provides cross-manufacturer equivalence with full parameter matching, including explicit moisture-resistant construction. It carries Active product status with confirmed Tape & Reel packaging. This part is suitable for applications requiring multi-source qualification or where YAGEO supply chain integration is preferred. All automotive and compliance certifications are maintained.

Both substitutes are qualified for direct replacement based on electrical performance, physical dimensions, temperature characteristics, and automotive compliance ratings.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM97R6F replace RK73H1HTTC97R6F in existing designs?

A: Yes. Both parts share identical resistance (97.6 Ohms), tolerance (±1%), power rating (0.05W), package (0201), composition (Thick Film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), AEC-Q200 rating, and compliance certifications. The primary difference is product status; RK73H1HTTCM97R6F is Active while RK73H1HTTC97R6F is Not For New Designs.

Q: Is AC0201FR-0797R6L compatible with RK73H1HTTC97R6F?

A: Yes. AC0201FR-0797R6L meets all electrical and mechanical specifications required for substitution. It is manufactured by YAGEO and carries Active product status. Both parts are AEC-Q200 qualified, moisture-resistant, ROHS3 compliant, and packaged in 0201 (0603 Metric) format with identical performance characteristics.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: resistance value (97.6 Ohms), tolerance (±1%), power rating (0.05W), package type (0201), composition (Thick Film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, moisture resistance, RoHS compliance, and MSL rating (1).

Q: Does packaging type affect substitution?

A: Packaging type (Tape & Reel vs. other formats) affects supply chain logistics and handling but does not affect electrical or mechanical compatibility. Both RK73H1HTTC97R6F and AC0201FR-0797R6L are supplied in Tape & Reel format. RK73H1HTTCM97R6F packaging type is not specified but does not impact functional equivalence.

Q: Are all substitutes suitable for automotive applications?

A: Yes. All identified substitutes carry AEC-Q200 qualification, confirming suitability for automotive applications. Operating temperature range (-55°C ~ 155°C) and moisture resistance specifications support automotive environmental requirements.

Q: What is the significance of "Not For New Designs" status?

A: This status indicates the RK73H1HTTC97R6F is in mature or end-of-life phase. Substitutes with Active status (RK73H1HTTCM97R6F and AC0201FR-0797R6L) offer improved long-term availability and manufacturing support for ongoing production and field service applications.
