Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Resistance value: 23.2 kOhms (exact match required)
Package: 0402 (1005 Metric) (exact match required)
Power rating: 0.063W minimum (equal or higher acceptable)
Composition: Thin Film (exact match required)
Operating temperature range: Must encompass or equal -55°C to 155°C minimum
RoHS compliance: ROHS3 Compliant (required)

Secondary Substitution Parameters:

Tolerance: ±1% or better (tighter tolerance acceptable as upgrade)
Temperature coefficient: ±50ppm/°C or better (lower coefficient acceptable as upgrade)
Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® (format interchangeability depends on assembly process)

Substitute parts are grouped by tolerance specification, as this parameter directly affects circuit performance in precision applications. All identified substitutes maintain identical resistance value, package dimensions, and power rating.

Engineering Selection Recommendations

YAGEO RT Series (±0.1% Tolerance Upgrades): RT0402BRD0723K2L and RT0402BRE0723K2L provide improved tolerance (±0.1% vs. ±1%) and reduced temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Both maintain ROHS3 compliance and active product status. Selection between these two depends on packaging format requirements: Cut Tape & Digi-Reel® for automated high-speed assembly, or Tape & Reel for standard reel-based processes.

YAGEO RT0402DRE0723K2L (±0.5% Tolerance): Intermediate tolerance option maintaining ±50ppm/°C temperature coefficient. Suitable for applications where ±1% tolerance is marginal but ±0.1% is unnecessary. Available in Cut Tape & Digi-Reel® format.

TE Connectivity CPF0402B23K2E1: Cross-manufacturer alternative with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maintains ROHS3 compliance and identical package specifications. Provides supply chain diversification.

Panasonic ERA-2AEB2322X: Automotive-qualified option (AEC-Q200) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Suitable for automotive and mission-critical applications requiring automotive-grade component certification. Height specification differs slightly (0.40mm vs. 0.35mm seated height).

Susumu RR0510P-2322-D: Alternative manufacturer with ±0.5% tolerance and ±25ppm/°C temperature coefficient. Operating temperature range limited to -55°C to 125°C (vs. 155°C maximum). Suitable for applications not requiring extended high-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0723K2L replace RT0402FRE0723K2L directly? A: Yes. Both components have identical resistance (23.2 kOhms), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). RT0402BRD0723K2L provides superior tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C). The only difference is packaging format: Cut Tape & Digi-Reel® versus Tape & Reel. Verify your assembly equipment compatibility with the packaging format.

Q: What is the difference between RT0402BRD0723K2L and RT0402BRE0723K2L? A: Both have identical electrical specifications (23.2 kOhms, ±0.1% tolerance, 0.063W power rating). The difference is packaging format: RT0402BRD0723K2L uses Cut Tape & Digi-Reel®, while RT0402BRE0723K2L uses standard Tape & Reel. Temperature coefficient differs: RT0402BRD0723K2L is ±25ppm/°C, RT0402BRE0723K2L is ±50ppm/°C. Select based on your assembly process requirements and temperature stability needs.

Q: Is ERA-2AEB2322X suitable for automotive applications? A: Yes. ERA-2AEB2322X carries AEC-Q200 automotive qualification. It meets automotive-grade reliability and performance standards. All other substitute parts lack automotive certification.

Q: Can RR0510P-2322-D be used in applications requiring 155°C operation? A: No. RR0510P-2322-D maximum operating temperature is 125°C. It is not suitable for applications requiring operation above 125°C. Use RT0402FRE0723K2L, RT0402BRD0723K2L, RT0402BRE0723K2L, CPF0402B23K2E1, or ERA-2AEB2322X for full -55°C to 155°C range.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All identified substitute parts maintain ROHS3 compliance. ERA-2AEB2322X REACH status is listed as "REACH Unaffected" rather than explicitly stated compliance; verify with manufacturer if REACH documentation is required for your application.

Q: What tolerance should I select for my application? A: Tolerance selection depends on circuit requirements. RT0402FRE0723K2L (±1%) is suitable for general-purpose applications. ±0.5% options (RT0402DRE0723K2L, RR0510P-2322-D) are appropriate for moderate precision requirements. ±0.1% options (RT0402BRD0723K2L, RT0402BRE0723K2L, CPF0402B23K2E1, ERA-2AEB2322X) are required for precision analog circuits, measurement instrumentation, and high-accuracy signal conditioning.

Q: Do all parts have identical physical dimensions? A: All parts use 0402 (1005 Metric) package with dimensions 0.039" L × 0.020" W (1.00mm × 0.50mm). Seated height varies slightly: RT0402FRE0723K2L, RT0402BRD0723K2L, RT0402BRE0723K2L, and CPF0402B23K2E1 are 0.014" (0.35mm); ERA-2AEB2322X and RR0510P-2322-D are 0.016" (0.40mm). This difference is negligible for standard PCB assembly but should be verified for applications with tight vertical clearance constraints.
