Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F1873CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (187 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Parameters: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W), and number of terminations (2) must be identical to ensure PCB footprint compatibility.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH status must be maintained.

Composition: Thick film construction is required for functional equivalence.

All substitute parts listed below satisfy these criteria. Additional features such as Automotive AEC-Q200 certification represent enhanced specifications that do not prevent substitution but indicate suitability for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active in product status and fully compliant with RoHS3 and REACH regulations, ensuring regulatory compatibility with the original RC2012F1873CS.

RC0805FR-07187KL (YAGEO): Direct functional equivalent with identical electrical and environmental specifications. Packaging available in Cut Tape and Digi-Reel formats. Seated height of 0.024" (0.60mm) is within acceptable PCB assembly tolerances.

CRCW0805187KFKEA (Vishay Dale): Meets all electrical and mechanical requirements. Includes Automotive AEC-Q200 certification, indicating enhanced reliability for automotive applications. Lowest seated height at 0.020" (0.50mm) provides additional clearance margin in space-constrained layouts.

ERJ-6ENF1873V (Panasonic Electronic Components): Fully equivalent with Automotive AEC-Q200 certification. Seated height of 0.028" (0.70mm) is the highest among substitutes but remains within standard PCB assembly specifications.

RMCF0805FT187K (Stackpole Electronics Inc): Complete electrical and mechanical equivalence with Automotive AEC-Q200 certification. Seated height of 0.026" (0.65mm) matches the original part specification.

Selection among these substitutes depends on packaging format requirements, supply chain availability, and application-specific certifications. All parts are suitable for direct replacement in non-automotive and automotive applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07187KL replace RC2012F1873CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (187 kOhms, ±1%, 0.125W), package type (0805 / 2012 Metric), and environmental ratings. The seated height difference of 0.002" (0.06mm) is negligible for standard PCB assembly processes.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous reels for automated pick-and-place assembly. Cut Tape (CT) is supplied in strips for manual or semi-automated handling. Both formats contain identical components; packaging selection depends on assembly equipment and production volume.

Q: Why do some substitutes have Automotive AEC-Q200 certification?

A: AEC-Q200 certification indicates the component meets automotive industry reliability and qualification standards. Parts with this certification are suitable for both automotive and general industrial applications. Parts without this certification are equally suitable for non-automotive applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes are ROHS3 Compliant and REACH Unaffected, matching the regulatory status of the original RC2012F1873CS.

Q: Does seated height variation affect circuit performance?

A: Seated height variations (0.020" to 0.028") are within standard PCB assembly tolerances and do not affect electrical performance. Height differences are relevant only for mechanical clearance in space-constrained designs.

Q: Can I use CRCW0805187KFKEA in a non-automotive application?

A: Yes. Automotive AEC-Q200 certification indicates enhanced qualification; parts with this certification are fully compatible with non-automotive applications and offer equivalent or superior reliability.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts have MSL 1 rating, eliminating moisture-related handling constraints.
