RNCF0402BKE23K7 Equivalent & Substitute Parts

Part Overview

The RNCF0402BKE23K7 is a 23.7 kOhms ±0.1% thin film chip resistor manufactured by Stackpole Electronics Inc. This 0402 (1005 Metric) surface mount component is rated for 0.1W power dissipation and meets automotive AEC-Q200 qualification standards. The part is currently in active production status with 887 units available in inventory. Equivalent and substitute parts are identified when applications require alternative sourcing due to supply constraints, lead time considerations, or inventory availability while maintaining identical electrical and mechanical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNCF0402BKE23K7 is determined by the following critical parameters:

Resistance value must be exactly 23.7 kOhms with tolerance of ±0.1%. Package configuration must be 0402 (1005 Metric) to ensure mechanical and electrical compatibility with printed circuit board layouts. Composition must be thin film to maintain temperature coefficient and tolerance specifications. Automotive AEC-Q200 qualification is required for applications demanding automotive-grade reliability. Operating temperature range must encompass -55°C to 155°C. RoHS3 compliance and MSL 1 rating must be maintained.

The ERA-2AEB2372X manufactured by Panasonic Electronic Components qualifies as a direct substitute based on these parameters. While the power rating differs (0.063W versus 0.1W), this represents a conservative design margin where the substitute part can safely operate in applications designed for the higher-rated main part.

Parameter Comparison

Engineering Selection Recommendations

Both the RNCF0402BKE23K7 and ERA-2AEB2372X are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on availability, lead time requirements, and application power dissipation margins. The ERA-2AEB2372X offers higher inventory availability (2792 units) compared to the RNCF0402BKE23K7 (887 units). The lower power rating of the ERA-2AEB2372X (0.063W) is suitable for applications where circuit design margins accommodate this specification. Both parts maintain identical electrical performance through resistance value, tolerance, temperature coefficient, and operating temperature range. The marginal height difference (0.35mm versus 0.40mm) is negligible for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEB2372X replace RNCF0402BKE23K7 in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, maintain identical resistance (23.7 kOhms ±0.1%), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part is suitable for automotive-grade designs.

Q: What is the significance of the power rating difference?

A: The RNCF0402BKE23K7 is rated at 0.1W while the ERA-2AEB2372X is rated at 0.063W. In applications designed for the higher-rated part, the lower-rated substitute operates with increased thermal margin. Verify that circuit power dissipation does not exceed 0.063W for the substitute part.

Q: Are the physical dimensions compatible?

A: Both parts use the 0402 (1005 Metric) package with identical length and width (0.039" x 0.020"). Height differs slightly (0.35mm versus 0.40mm), which does not affect standard PCB assembly compatibility.

Q: Do both parts meet RoHS and REACH requirements?

A: Yes. Both RNCF0402BKE23K7 and ERA-2AEB2372X are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines substitution eligibility?

A: Substitution is valid when resistance value, tolerance, package type, composition, temperature coefficient, operating temperature range, and automotive qualification remain identical. Power rating may be lower in the substitute part provided circuit design accommodates this specification.
