Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.37 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match or wider range acceptable)

Mechanical Equivalence Requirements:

• Package format: 0402 (1005 Metric) (exact match)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) (exact match)
• Number of terminations: 2 (exact match)

Environmental & Compliance Requirements:

• Composition: Thick Film (exact match)
• Moisture Sensitivity Level: MSL 1 or better (exact match or lower MSL acceptable)
• RoHS Status: ROHS3 Compliant (exact match)
• REACH Status: REACH Unaffected (exact match)

All identified substitute parts meet these criteria. Parts designated as "Direct" substitutes match all parameters including packaging format. Parts designated as "Similar" match all electrical and mechanical parameters but may include additional certifications (AEC-Q200 automotive qualification) or differ in power rating specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

CR0402-FX-2371GLF (Bourns Inc.) and RC0402FR-072K37L (YAGEO) are direct functional equivalents to RC1005F2371CS. Both maintain identical electrical parameters, package dimensions, power rating, and compliance certifications. Selection between these options depends on packaging format preference (Tape & Reel vs. Cut Tape) and supplier availability.

Similar Substitutes with Enhanced Ratings:

AC0402FR-072K37L (YAGEO), CRCW04022K37FKED (Vishay Dale), ERJ-2RKF2371X (Panasonic Electronic Components), and RMCF0402FT2K37 (Stackpole Electronics Inc) are functionally equivalent with the addition of Automotive AEC-Q200 qualification. These parts meet all electrical and mechanical requirements of the primary part and include automotive-grade reliability certification. The ERJ-2RKF2371X carries a higher power rating (0.1W vs. 0.063W), which provides additional thermal margin in applications where power dissipation approaches component limits.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2371GLF replace RC1005F2371CS in all applications?

A: Yes. CR0402-FX-2371GLF is a direct substitute with identical electrical specifications (2.37 kΩ ±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The only difference is packaging format (Tape & Reel vs. Cut Tape). Electrical and mechanical compatibility is complete.

Q: What is the difference between RC0402FR-072K37L and AC0402FR-072K37L?

A: Both are YAGEO 2.37 kΩ ±1% 0402 resistors with identical electrical specifications. AC0402FR-072K37L includes Automotive AEC-Q200 qualification and moisture-resistant construction. RC0402FR-072K37L also includes moisture-resistant features. AC0402FR-072K37L is suitable for automotive applications requiring AEC-Q200 certification; RC0402FR-072K37L is suitable for general industrial applications.

Q: Why does ERJ-2RKF2371X have a different power rating (0.1W vs. 0.063W)?

A: ERJ-2RKF2371X is rated for 0.1W (1/10W) power dissipation compared to the 0.063W (1/16W) rating of RC1005F2371CS. This higher power rating provides additional thermal capacity and is functionally compatible for applications using the original 0.063W specification. The higher rating does not create incompatibility; it provides design margin.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification and REACH Unaffected status, matching the environmental and regulatory requirements of RC1005F2371CS.

Q: What packaging formats are available among the substitutes?

A: Substitute parts are available in two packaging formats: Cut Tape (CT) / Digi-Reel® and Tape & Reel (TR). RC1005F2371CS and AC0402FR-072K37L are supplied in Cut Tape format. CR0402-FX-2371GLF, RC0402FR-072K37L, CRCW04022K37FKED, ERJ-2RKF2371X, and RMCF0402FT2K37 are supplied in Tape & Reel format. Selection depends on assembly equipment and procurement requirements.

Q: Can automotive-qualified parts (AEC-Q200) be used in non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed general industrial specifications. AC0402FR-072K37L, CRCW04022K37FKED, ERJ-2RKF2371X, and RMCF0402FT2K37 are suitable for any application requiring 2.37 kΩ ±1% 0402 resistors, including non-automotive designs.

Q: What is MSL Level 1 and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts carry MSL 1 rating, meaning they can be stored and handled without special moisture control procedures, simplifying inventory management and reducing component preparation time.
