Engineering Selection Recommendations

RK73H1HTTCM2702F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications to the main part while carrying an "Active" product status. Selection of this part ensures continuity within the same manufacturer's product line and supports long-term supply chain stability. This option is preferred for applications requiring single-source component qualification.

AC0201FR-0727KL (YAGEO)

This part provides cross-manufacturer equivalence with identical electrical and mechanical parameters. YAGEO's AC series thick film resistor meets all AEC-Q200 automotive requirements and RoHS3 compliance standards. Selection of this part expands supply chain options and provides alternative sourcing for production continuity. Both manufacturers' parts are qualified for automotive applications and carry equivalent reliability certifications.

Both substitute parts are suitable for direct replacement in existing designs and new production applications. Selection between them depends on supply chain strategy, existing qualification documentation, and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2702F be used as a direct replacement for RK73H1HTTC2702F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., share identical electrical specifications (27 kOhms ±1%, 0.05W), operate across the same temperature range (-55°C ~ 155°C), and meet AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM2702F is Active, while the original is Not For New Designs.

Q: Is AC0201FR-0727KL compatible with RK73H1HTTC2702F in automotive applications?

A: Yes. AC0201FR-0727KL meets all electrical and mechanical requirements: 27 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 qualification, and RoHS3 compliance. Cross-manufacturer substitution is valid based on parameter equivalence.

Q: What is the significance of the 0201 package format?

A: The 0201 package (0.60mm x 0.30mm) is a miniature surface-mount format. All listed parts use this identical package, ensuring mechanical compatibility with PCB layouts, pick-and-place equipment, and reflow soldering processes. No design modifications are required when substituting between these parts.

Q: Does MSL 1 (Unlimited) rating affect storage or handling?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special dry-pack storage, desiccant handling, or bake-out procedures prior to soldering. Standard component storage conditions apply.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RK73H1HTTCM2702F and AC0201FR-0727KL are both ROHS3 Compliant, matching the original part's environmental compliance status. Both parts are suitable for applications with RoHS3 requirements.

Q: What is the difference between "Not For New Designs" and "Active" product status?

A: "Not For New Designs" indicates the original part is in end-of-life phase and should not be selected for new product development. "Active" status indicates the substitute parts are in current production and recommended for new designs. For ongoing production support, either substitute part is appropriate.
