Part Overview

The RT0805BRE0723K7L is a 23.7 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W). Manufactured by YAGEO, this component is actively produced and ROHS3 compliant. Substitute parts are identified to provide design flexibility, inventory alternatives, and application-specific options while maintaining electrical and mechanical compatibility within the 0805 package class.

Key Parameters

Parameter	Value
Resistance	23.7 kOhms
Tolerance	±0.1%
Power Rating	0.125W (1/8W)

Composition	Thin Film
Operating Temperature Range	-55°C ~ 155°C
RoHS Status	ROHS3 Compliant
Moisture Sensitivity Level	1 (Unlimited)

Substitute Part Grouping Explanation

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

Resistance Value: Must be 23.7 kOhms
Tolerance: Must be ±0.1%
Package: Must be 0805 (2012 Metric)
Composition: Must be Thin Film
Operating Temperature Range: Must support -55°C ~ 155°C
RoHS Compliance: Must be ROHS3 Compliant
Moisture Sensitivity: Must be MSL 1 or equivalent

All identified substitute parts meet these core electrical and mechanical requirements. Variations in power rating (0.125W vs. 0.25W), temperature coefficient, and application-specific features (automotive qualification, current sense capability) are secondary differentiators that do not preclude substitution within the specified parameter envelope.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance. Selection among equivalents should be based on:

RT0805BRD0723K7L (YAGEO): Direct YAGEO alternative with improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Identical power rating and package dimensions. Suitable for applications requiring tighter thermal stability.

3-2176093-9 (TE Connectivity): Offers increased power dissipation capability (0.25W vs. 0.125W) within the same 0805 package footprint. Marginal height increase (0.026" vs. 0.024"). Applicable where thermal margin or power handling is a design consideration.

ERA-6AEB2372V (Panasonic): Automotive-qualified component (AEC-Q200 rated) with ±25ppm/°C temperature coefficient. Maintains 0.125W power rating and standard 0805 dimensions. Specified for automotive and high-reliability applications.

CRT0805-BZ-2372ELF (Bourns): Current sense thin film resistor with ±50ppm/°C temperature coefficient. Designed for precision current measurement circuits. Marginal height increase (0.026" vs. 0.024"). Application-specific selection for current sensing topologies.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0723K7L replace RT0805BRE0723K7L directly?

A: Yes. Both are YAGEO 23.7 kOhms ±0.1% thin film resistors in 0805 package with identical power rating and operating temperature range. The primary difference is improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C), which enhances thermal stability without affecting mechanical compatibility.

Q: Is the 3-2176093-9 (0.25W) suitable for 0.125W circuit applications?

A: Yes. Higher power rating does not preclude use in lower-power applications. The 0.25W rating provides additional thermal margin. Verify that the marginal height increase (0.026" vs. 0.024") does not conflict with PCB layout constraints or component clearance requirements.

Q: What is the difference between ERA-6AEB2372V and the standard YAGEO parts?

A: ERA-6AEB2372V is automotive-qualified (AEC-Q200) with ±25ppm/°C temperature coefficient. It is specified for automotive and high-reliability applications where component qualification and traceability are mandatory. Electrical and mechanical parameters are otherwise equivalent to RT0805BRD0723K7L.

Q: When should CRT0805-BZ-2372ELF be selected?

A: CRT0805-BZ-2372ELF is a current sense thin film resistor optimized for precision current measurement circuits. Select this part when the application requires dedicated current sensing topology or when Bourns current sense resistor specifications are mandated by design requirements.

Q: Are all substitute parts MSL 1 rated?

A: Yes. All listed parts are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Do package dimensions vary among substitutes?

A: All parts conform to 0805 (2012 Metric) package specification. Height-seated maximum varies slightly: 0.024" (0.60mm) for YAGEO RT0805BRE0723K7L, RT0805BRD0723K7L, and Panasonic ERA-6AEB2372V; 0.026" (0.65mm) for TE Connectivity 3-2176093-9 and Bourns CRT0805-BZ-2372ELF. Verify PCB layout clearance if height-sensitive applications are present.
