Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RK73H2HTTE2371F are qualified based on the following criteria:

Electrical Parameters: Resistance value (2.37 kOhms), tolerance (±1%), and power rating (0.75W) must match exactly.

Mechanical Parameters: Package type (2010 / 5025 Metric), physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm), and seated height (0.028" / 0.70mm) must be identical.

Environmental & Compliance: Temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, RoHS3 compliance, and MSL rating (1) must be maintained.

Composition: Thick film construction is required for thermal and performance characteristics.

All identified substitutes meet these criteria and are functionally equivalent for direct replacement in automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status): CRCW20102K37FKEF (Vishay Dale) and RMCF2010FT2K37 (Stackpole Electronics Inc) are recommended as primary alternatives. Both maintain active product status, ensuring long-term availability and supply chain stability. CRCW20102K37FKEF is supplied in Tape & Reel packaging, matching the original part's format. RMCF2010FT2K37 is supplied in Cut Tape format, suitable for applications where alternative packaging is acceptable.

Secondary Substitute (Legacy Status): ERJ-12SF2371U (Panasonic Electronic Components) is marked as "Not For New Designs" and should be used only for legacy system maintenance or repair applications where existing inventory exists. This part maintains full electrical and mechanical equivalence but is not recommended for new product development.

Compliance Assurance: All substitutes maintain AEC-Q200 automotive qualification, RoHS3 compliance, and MSL rating 1, ensuring compatibility with automotive and industrial specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW20102K37FKEF replace RK73H2HTTE2371F directly? A: Yes. CRCW20102K37FKEF matches all electrical parameters (2.37 kOhms ±1%, 0.75W), mechanical dimensions (2010 package), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and automotive compliance (AEC-Q200, RoHS3). Both are supplied in Tape & Reel packaging.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly lines. Cut Tape supplies components on tape segments, typically for lower-volume or manual assembly processes. Both formats contain identical components; packaging choice depends on assembly equipment and volume requirements.

Q: Why is ERJ-12SF2371U marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active development and recommends against using this part in new product designs. However, it remains functionally equivalent and may be used for legacy system repairs or maintenance where existing inventory is available.

Q: Are all substitutes suitable for automotive applications? A: Yes. All listed substitutes maintain AEC-Q200 automotive qualification, confirming suitability for automotive-grade applications requiring reliability and environmental stress testing compliance.

Q: What parameters must remain constant for substitution? A: Resistance value (2.37 kOhms), tolerance (±1%), power rating (0.75W), package type (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 compliance must all remain unchanged for functional equivalence.
