Engineering Selection Recommendations

RK73H1HTTCM3003F (KOA Speer Electronics, Inc. - MFR Recommended Substitute)

This part is the manufacturer-recommended substitute for the RK73H1HTTC3003F. It maintains identical electrical and mechanical specifications while carrying Active product status. The RK73H1HTTCM3003F is the preferred choice for new production runs and design revisions, as it represents the current generation within the KOA Speer RK73H series. All compliance certifications, including AEC-Q200 automotive rating and ROHS3 compliance, are maintained.

AC0201FR-07300KL (YAGEO - Direct Substitute)

This part provides cross-manufacturer substitution from YAGEO's AC series. It meets all electrical and mechanical parameters of the RK73H1HTTC3003F, including AEC-Q200 automotive qualification and ROHS3 compliance. The AC0201FR-07300KL is suitable for applications requiring multi-source component qualification or where YAGEO supply chain integration is preferred. Product status is Active.

Both substitute parts are electrically and mechanically interchangeable with the RK73H1HTTC3003F within the specified operating parameters and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM3003F be used as a direct replacement for RK73H1HTTC3003F?

A: Yes. The RK73H1HTTCM3003F is the manufacturer-recommended substitute and maintains identical electrical specifications (300 kOhms ±1%, 0.05W), package format (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and all compliance ratings (AEC-Q200, ROHS3, MSL 1). It is functionally equivalent for all applications.

Q: What is the difference between RK73H1HTTC3003F and RK73H1HTTCM3003F?

A: Both parts are from KOA Speer Electronics' RK73H series with identical electrical and mechanical specifications. The primary difference is product lifecycle status: RK73H1HTTC3003F is marked "Not For New Designs," while RK73H1HTTCM3003F is Active. The "M" designation in the part number indicates the current production variant.

Q: Can AC0201FR-07300KL from YAGEO replace the KOA part?

A: Yes. The AC0201FR-07300KL meets all specified parameters: 300 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive rating, ROHS3 compliance, and MSL 1 moisture sensitivity. It is a qualified cross-manufacturer substitute.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. Both RK73H1HTTCM3003F and AC0201FR-07300KL carry AEC-Q200 automotive qualification, matching the original RK73H1HTTC3003F specification.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All three parts (main and substitutes) carry this rating, ensuring consistent handling and storage procedures across all variants.

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

A: No. All parts use identical 0201 (0603 Metric) package format with matching 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: Which substitute should be selected for new production?

A: RK73H1HTTCM3003F is recommended for new production as it carries Active product status and is the manufacturer's current offering. AC0201FR-07300KL is suitable where multi-source qualification or YAGEO supply chain preference is established.
