Engineering Selection Recommendations

RK73H1HTTCM1962F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications and package format as the main part. The primary distinction is active product status, indicating ongoing manufacturer support and availability. This part is suitable for new production runs and design updates. Note that moisture-resistant construction is not specified for this variant, which may be a consideration for applications requiring enhanced environmental protection.

AC0201FR-0719K6L (YAGEO)

This part is a direct cross-reference from YAGEO and meets all electrical and mechanical parameters. It maintains moisture-resistant construction equivalent to the main part and carries active product status. This option provides supply chain diversification through an alternative manufacturer while preserving all critical performance characteristics and environmental ratings.

Both substitute parts are ROHS3 compliant, AEC-Q200 rated, and suitable for automotive applications across the specified temperature range. Selection between these options should be based on supply availability, procurement lead times, and existing qualification status within your organization's component database.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1962F be used as a direct replacement for RK73H1HTTC1962F?

A: Yes. Both parts share identical electrical specifications (19.6 kOhms ±1%, 0.05W), package format (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and automotive rating (AEC-Q200). The primary difference is product status; RK73H1HTTCM1962F is active while the main part is not for new designs.

Q: What is the difference between RK73H1HTTC1962F and AC0201FR-0719K6L?

A: Both parts are electrically and mechanically identical in all specified parameters. The differences are manufacturer (KOA Speer vs. YAGEO) and packaging designation. RK73H1HTTC1962F is not for new designs, while AC0201FR-0719K6L is active. Both include moisture-resistant construction and AEC-Q200 automotive qualification.

Q: Are all three parts interchangeable in PCB assembly?

A: Yes. All three parts share the 0201 (0603 Metric) package format with identical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and height (0.010" maximum seated height). They are mechanically and electrically interchangeable in PCB layouts designed for this package.

Q: Which substitute should I select for new product designs?

A: Both RK73H1HTTCM1962F and AC0201FR-0719K6L carry active product status and are suitable for new designs. Selection depends on your organization's existing supplier relationships, qualification records, and supply chain strategy. Both meet all automotive and compliance requirements.

Q: Does moisture resistance matter for my application?

A: The main part RK73H1HTTC1962F and AC0201FR-0719K6L both specify moisture-resistant construction. RK73H1HTTCM1962F does not list this feature. If your application requires moisture-resistant components, select either the main part or AC0201FR-0719K6L. All three parts carry MSL 1 (Unlimited) rating, indicating minimal moisture sensitivity risk.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the AEC-Q200 rating?

A: AEC-Q200 is the automotive electronics council qualification standard for passive components. All three parts meet this standard, confirming suitability for automotive applications across the specified temperature range (-55°C ~ 155°C).
