Engineering Selection Recommendations

RK73H1HTTCM6201F (KOA Speer Electronics, Inc.) - MFR Recommended Substitute:

This part is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. It maintains the same series designation (RK73H) and carries Active product status, ensuring continued availability and support. All electrical parameters, package specifications, and compliance certifications are identical to the primary part. The primary distinction is the absence of explicit moisture resistance specification in the provided data, though the part retains AEC-Q200 qualification and MSL 1 rating. This substitute is suitable for direct replacement in existing designs.

AC0201FR-076K2L (YAGEO) - Direct Cross-Reference Substitute:

This YAGEO part provides full electrical and mechanical equivalence with explicit moisture-resistant construction matching the original specification. It carries Active product status with higher inventory availability (19,490 pcs) compared to the primary part. All critical parameters—resistance, tolerance, power rating, package dimensions, temperature range, and AEC-Q200 automotive qualification—are identical. This part is suitable for direct substitution in applications requiring moisture-resistant thick film construction.

Both substitute parts satisfy all electrical, mechanical, and compliance requirements for functional equivalence with the RK73H1HTTC6201F.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6201F be used as a direct replacement for RK73H1HTTC6201F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., share the same series designation (RK73H), and have identical electrical specifications (6.2 kOhms ±1%, 0.05W), package type (0201), temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM6201F is Active, while RK73H1HTTC6201F is Not For New Designs.

Q: What is the difference between RK73H1HTTC6201F and AC0201FR-076K2L?

A: Both parts are electrically and mechanically equivalent with identical resistance (6.2 kOhms ±1%), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 rating. The primary difference is manufacturer: KOA Speer Electronics, Inc. versus YAGEO. Both are Active status with moisture-resistant construction and ROHS3 compliance.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification, which certifies reliability and performance in automotive environments. They meet automotive-grade standards for temperature cycling, moisture resistance, and failure rate requirements.

Q: What does "Not For New Designs" mean for RK73H1HTTC6201F?

A: This status indicates the part is in end-of-life phase and is not recommended for new product designs. However, it remains available for existing designs and legacy system support. The substitute parts RK73H1HTTCM6201F and AC0201FR-076K2L both carry Active status and are suitable for new designs.

Q: Can I mix these parts in the same production batch?

A: All three parts meet identical electrical and mechanical specifications, so they are functionally interchangeable. However, mixing manufacturers or product statuses in a single batch may require documentation and traceability procedures depending on your quality and procurement standards.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component can be stored indefinitely without special moisture-control packaging or baking procedures before soldering. This simplifies inventory management and reduces handling requirements.

Q: Are there any package or footprint differences between these parts?

A: No. All three parts use the identical 0201 (0603 Metric) package with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are footprint-compatible and require no PCB redesign.
