Engineering Selection Recommendations

RK73H1HTTCM1102F (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 RK73H1HTTCM1102F carries an Active product status, ensuring long-term availability and supply chain continuity. All compliance certifications (AEC-Q200, ROHS3, MSL 1) are maintained. This substitute is the preferred choice for applications requiring continuity within the KOA Speer product line.

AC0201FR-0711KL (YAGEO)

This part is a direct cross-reference substitute from YAGEO, offering equivalent electrical and mechanical specifications. The AC0201FR-0711KL is rated for automotive applications (AEC-Q200) and includes moisture-resistant construction. It carries Active product status with confirmed availability. This substitute is suitable for applications where multi-source component qualification is required or where YAGEO supply chain integration is preferred.

Both substitutes satisfy all electrical, mechanical, and compliance requirements specified for the RK73H1HTTC1102F and are suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1102F be used as a direct replacement for RK73H1HTTC1102F?

A: Yes. Both parts share identical electrical specifications (11 kOhms ±1%, 0.05W), package format (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive rating (AEC-Q200). The primary difference is product status: RK73H1HTTCM1102F is Active, while RK73H1HTTC1102F is Not For New Designs.

Q: What is the difference between RK73H1HTTC1102F and AC0201FR-0711KL?

A: Both parts are electrically and mechanically equivalent with identical resistance (11 kOhms ±1%), power rating (0.05W), package (0201), and automotive certification (AEC-Q200). The primary differences are manufacturer (KOA Speer vs. YAGEO) and product status (both are either Not For New Designs or Active). Both are suitable for direct substitution.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 0201 (0603 Metric) package with identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on the same PCB layout.

Q: Do all substitute parts meet automotive AEC-Q200 requirements?

A: Yes. RK73H1HTTCM1102F and AC0201FR-0711KL both carry AEC-Q200 automotive ratings, matching the original RK73H1HTTC1102F specification.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected.

Q: Which substitute should be selected for new production?

A: RK73H1HTTCM1102F is recommended for new production due to its Active product status and manufacturer recommendation from KOA Speer Electronics, Inc. AC0201FR-0711KL is suitable where multi-source qualification or YAGEO supply chain integration is required.
