Qualifying Parameters for Substitution:

• Resistance value: 9.76 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package format: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive compliance: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical compatibility within the original application circuit.

Engineering Selection Recommendations

RK73H1HTTCM9761F (KOA Speer Electronics, Inc.) - MFR Recommended Substitute

This part is the manufacturer-recommended substitute for the RK73H1HTTC9761F. It maintains identical electrical specifications and AEC-Q200 automotive compliance. The primary distinction is active product status, indicating ongoing manufacturer support and availability. This part is suitable for new production runs and design transitions. Note that moisture resistance is not explicitly specified for this variant, though MSL 1 rating is maintained.

AC0201FR-079K76L (YAGEO) - Direct Manufacturer Substitute

This YAGEO part provides full electrical and mechanical equivalence to the original RK73H1HTTC9761F, including explicit moisture-resistant thick film composition. It carries active product status with AEC-Q200 automotive qualification and ROHS3 compliance. This part is suitable for applications requiring cross-manufacturer sourcing or supply chain diversification while maintaining identical performance characteristics.

Both substitute parts satisfy all critical parameters required for direct substitution in the original application circuit.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM9761F be used as a direct replacement for RK73H1HTTC9761F?

A: Yes. Both parts share identical resistance (9.76 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 rating, RoHS3 compliance, and MSL 1 rating. The primary difference is product status; RK73H1HTTCM9761F is active while the original is not for new designs.

Q: What is the difference between RK73H1HTTC9761F and AC0201FR-079K76L?

A: Both parts are electrically and mechanically equivalent across all specified parameters. The primary differences are manufacturer (KOA vs. YAGEO) and explicit moisture-resistant specification for the YAGEO part. Both maintain AEC-Q200 automotive compliance and active product status.

Q: Are all three parts interchangeable in automotive applications?

A: Yes. All three parts meet AEC-Q200 automotive qualification, operate across -55°C ~ 155°C, maintain ±1% tolerance, and are rated for 0.05W in 0201 package format. They are suitable for direct substitution in automotive circuit designs.

Q: Does packaging format affect substitution compatibility?

A: The 0201 (0603 Metric) package format is identical across all three parts. Tape & Reel (TR) packaging is specified for RK73H1HTTC9761F and AC0201FR-079K76L. Packaging format does not affect electrical or mechanical compatibility; it affects only handling and assembly logistics.

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

A: This designation indicates the original RK73H1HTTC9761F is in mature or end-of-life phase. For new design work, RK73H1HTTCM9761F or AC0201FR-079K76L are recommended due to active product status and ongoing manufacturer support.

Q: Are moisture-resistant specifications critical for substitution?

A: Moisture resistance is specified for RK73H1HTTC9761F and AC0201FR-079K76L but not explicitly stated for RK73H1HTTCM9761F. However, all three parts maintain MSL 1 (Unlimited) rating, indicating equivalent moisture handling capability. For applications with specific moisture exposure requirements, verify environmental conditions against MSL 1 specifications.
