Engineering Selection Recommendations

RK73H1HTTCM1622F (KOA Speer Electronics, Inc.)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications and AEC-Q200 automotive qualification. The primary distinction is active product status, indicating ongoing manufacturing and supply availability. This part is suitable for direct replacement in existing designs. Note that moisture resistance is not specified for this variant; applications requiring explicit moisture-resistant construction should reference the original part specification.

AC0201FR-0716K2L (YAGEO)

This part is a cross-manufacturer substitute from YAGEO, offering identical electrical parameters, AEC-Q200 qualification, and moisture-resistant construction matching the original part. Active product status ensures supply continuity. This part is suitable for applications where multi-source component qualification is required or where YAGEO supply chain integration is preferred.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1622F be used as a direct replacement for RK73H1HTTC1622F?

A: Yes. Both parts share identical resistance (16.2 kOhms), tolerance (±1%), power rating (0.05W), package (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 qualification, RoHS3 compliance, and MSL rating (1). The primary difference is product status: RK73H1HTTCM1622F is active, while RK73H1HTTC1622F is not for new designs. Moisture resistance specification differs between the two variants.

Q: Can AC0201FR-0716K2L be used as a direct replacement for RK73H1HTTC1622F?

A: Yes. Both parts share identical electrical specifications, package dimensions, AEC-Q200 automotive qualification, RoHS3 compliance, and MSL rating. AC0201FR-0716K2L is manufactured by YAGEO and maintains moisture-resistant construction. The primary difference is manufacturer origin.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact matching of: resistance value (16.2 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, RoHS3 compliance, and MSL rating (1). All substitute parts listed meet these criteria.

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

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

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

A: AEC-Q200 qualification indicates the component meets automotive-grade reliability standards established by the Automotive Electronics Council. All listed parts carry this qualification, confirming suitability for automotive applications and harsh operating environments.

Q: Does moisture resistance differ between substitute options?

A: Yes. RK73H1HTTC1622F and AC0201FR-0716K2L both specify moisture-resistant construction. RK73H1HTTCM1622F does not include moisture resistance in its specification. Applications requiring explicit moisture resistance should use either the original part or AC0201FR-0716K2L.
