Engineering Selection Recommendations

RK73H1HTTCM2322F (KOA Speer Electronics, Inc. - MFR Recommended Substitute)

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It carries Active product status and maintains all electrical and mechanical specifications identical to the main part. The RK73H1HTTCM2322F is ROHS3 compliant and MSL 1 rated. Note that this variant does not specify moisture-resistant construction in its feature set, distinguishing it from the original RK73H1HTTC2322F.

AC0201FR-0723K2L (YAGEO - Direct Substitute)

This YAGEO part provides direct substitution with Active product status. The AC0201FR-0723K2L maintains all critical electrical parameters: 23.2 kOhms ±1%, 0.05W power rating, ±200ppm/°C temperature coefficient, and -55°C to 155°C operating range. It includes moisture-resistant construction and AEC-Q200 automotive qualification. ROHS3 compliance and MSL 1 rating are confirmed. This part is suitable for applications requiring cross-manufacturer sourcing flexibility.

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement in circuits designed for the RK73H1HTTC2322F. Selection between them depends on supply chain availability, procurement preferences, and specific application requirements regarding moisture resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2322F replace RK73H1HTTC2322F in all applications?

A: The RK73H1HTTCM2322F matches all electrical specifications and physical dimensions. However, the original part specifies moisture-resistant construction while the HTTCM variant does not explicitly list this feature. For applications where moisture resistance is a design requirement, this distinction should be evaluated against specific environmental conditions.

Q: What is the difference between RK73H1HTTC2322F and RK73H1HTTCM2322F?

A: Both parts are manufactured by KOA Speer Electronics, Inc. with identical resistance (23.2 kOhms ±1%), power rating (0.05W), package (0201), and temperature specifications. The primary difference is product status: RK73H1HTTC2322F is "Not For New Designs" while RK73H1HTTCM2322F is "Active." The HTTCM variant does not specify moisture-resistant features in its description.

Q: Is AC0201FR-0723K2L from YAGEO compatible with RK73H1HTTC2322F?

A: Yes. The AC0201FR-0723K2L provides electrical and mechanical compatibility. Both parts share identical resistance value, tolerance, power rating, package format, temperature coefficient, and operating temperature range. Both are AEC-Q200 rated, ROHS3 compliant, and MSL 1 rated. The YAGEO part includes moisture-resistant construction matching the original specification.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, meeting the same reliability and quality standards as the original RK73H1HTTC2322F.

Q: Can these parts be used interchangeably on PCBs without layout modifications?

A: Yes. All parts maintain identical 0201 package dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). No PCB layout or footprint changes are required for substitution.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All listed parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Why is RK73H1HTTC2322F marked "Not For New Designs"?

A: This status indicates the part is in mature or end-of-life phase. KOA Speer Electronics recommends using RK73H1HTTCM2322F for new designs while the original part remains available for existing production and field support.
