Engineering Selection Recommendations

RK73H1HTTCM7150F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended upgrade path from the RK73H1HTTC7150F. Both components originate from the same manufacturer and share identical electrical specifications and package geometry. The RK73H1HTTCM7150F carries Active product status, ensuring continued availability and manufacturing support. This part satisfies all electrical and mechanical equivalence criteria. Note: The RK73H1HTTCM7150F does not specify moisture-resistant construction in the provided data, whereas the original part includes this feature. Evaluate moisture resistance requirements for your specific application before selection.

AC0201FR-07715RL (YAGEO)

This part provides cross-manufacturer equivalence with full electrical and mechanical compatibility. The AC0201FR-07715RL maintains all critical parameters including 715 Ohm resistance, ±1% tolerance, 0.05W power rating, AEC-Q200 automotive qualification, and moisture-resistant thick film construction. Active product status ensures supply chain continuity. This component is suitable for applications requiring multi-source qualification or where YAGEO supply chain integration is preferred.

Both substitute parts are qualified for direct replacement in existing designs and production environments where the RK73H1HTTC7150F is currently specified.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM7150F be used as a direct replacement for RK73H1HTTC7150F?

A: Yes. Both parts share identical electrical specifications (715 Ohms ±1%, 0.05W, ±200ppm/°C, -55°C ~ 155°C), package geometry (0201 / 0603 Metric), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM7150F is Active, while RK73H1HTTC7150F is Not For New Designs. Verify that moisture-resistant construction is not a critical requirement for your application, as this feature is not specified for the RK73H1HTTCM7150F.

Q: Is AC0201FR-07715RL compatible with designs using RK73H1HTTC7150F?

A: Yes. The AC0201FR-07715RL meets all electrical and mechanical equivalence criteria: 715 Ohms ±1%, 0.05W power rating, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, 0201 package, AEC-Q200 qualification, and moisture-resistant construction. Cross-manufacturer substitution is supported for this component.

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

A: Substitution eligibility is determined by three parameter categories: (1) Electrical parameters—resistance value, tolerance, power rating, temperature coefficient, and operating temperature range; (2) Mechanical parameters—package type, physical dimensions, and termination count; (3) Compliance parameters—AEC-Q200 automotive rating, moisture resistance, RoHS status, and moisture sensitivity level. All three categories must match for direct interchangeability.

Q: Can I use these substitutes in new designs?

A: RK73H1HTTCM7150F and AC0201FR-07715RL both carry Active product status and are suitable for new designs. The original RK73H1HTTC7150F is marked "Not For New Designs" and should not be specified for new development.

Q: Are there any packaging differences between these parts?

A: All three 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 of 0.010" (0.26mm). Packaging is fully compatible across all three components.

Q: What is the significance of AEC-Q200 qualification?

A: AEC-Q200 qualification indicates that the component meets automotive industry reliability and quality standards established by the Automotive Electronics Council. All three parts carry this certification, confirming suitability for automotive applications requiring stringent performance and durability specifications.
