Engineering Selection Recommendations

RK73H1HTTCM5622F (MFR Recommended Substitute):

This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical specifications, package dimensions, and automotive AEC-Q200 qualification. The primary distinction is active product status, making it the preferred choice for ongoing production and new procurement. This substitute is sourced from the original manufacturer, ensuring design continuity and supply chain stability. Note that moisture resistance is not explicitly specified in the available data for this variant.

AC0201FR-0756K2L (Direct Substitute):

This YAGEO component provides full electrical and mechanical equivalence with explicit moisture-resistant construction matching the original part. It carries active product status and maintains all required certifications including AEC-Q200, RoHS3 compliance, and MSL 1 rating. This substitute is suitable for applications requiring cross-manufacturer sourcing or where YAGEO supply chain availability is preferred. Inventory availability is higher than the KOA Speer recommended substitute.

Both substitutes are electrically and mechanically interchangeable with the RK73H1HTTC5622F and satisfy all automotive and compliance requirements specified for this 56.2 kOhms 0201 chip resistor application.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM5622F be used as a direct replacement for RK73H1HTTC5622F?

A: Yes. Both parts share identical resistance (56.2 kOhms), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status; RK73H1HTTCM5622F is active while the original is not for new designs.

Q: Is AC0201FR-0756K2L compatible with the original RK73H1HTTC5622F?

A: Yes. AC0201FR-0756K2L meets all electrical and mechanical specifications: 56.2 kOhms ±1%, 0.05W, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and AEC-Q200 qualification. It includes explicit moisture-resistant construction. The substitute is from YAGEO rather than KOA Speer Electronics, Inc.

Q: What are the critical parameters for substitution?

A: Substitutes must match: resistance value (56.2 kOhms), tolerance (±1%), power rating (0.05W), package type (0201 / 0603 metric), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical dimensions (0.024" L x 0.012" W, max height 0.010") and composition (thick film) must also align.

Q: Are both substitutes RoHS3 compliant?

A: Yes. Both RK73H1HTTCM5622F and AC0201FR-0756K2L are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original part's compliance profile.

Q: Which substitute should be selected for new production?

A: RK73H1HTTCM5622F is the manufacturer-recommended substitute with active product status from the original manufacturer. AC0201FR-0756K2L is an alternative with higher inventory availability and explicit moisture-resistant specification. Selection depends on supply chain preference and availability requirements.

Q: Do the substitutes maintain the same package and footprint?

A: Yes. All three parts use the 0201 package (0603 metric) 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 identical.
