RC2012F9310CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F9310CS is a 931 Ohm ±1% 0.125W thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is supplied in Tape & Reel packaging with 1089 pieces currently in stock inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility across multiple qualified suppliers is needed while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F9310CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (931 Ohms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package type (0805 / 2012 Metric), composition (Thick Film), and number of terminations (2) must match exactly.

Compliance Parameters: RoHS3 compliance and MSL 1 rating are required for all substitutes.

Packaging: Tape & Reel format is standard across all qualified substitutes.

All substitute parts listed below meet these criteria without exception. Height variations within the seated maximum dimension do not affect substitution eligibility as they remain within standard PCB assembly tolerances for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07931RL replace RC2012F9310CS in all applications?

A: Yes. RC0805FR-07931RL meets all electrical and mechanical specifications. The 0.60mm seated height versus 0.66mm on the original part remains within standard PCB assembly tolerances for 0805 components and does not affect functionality or reliability.

Q: What is the difference between standard and automotive-qualified versions?

A: CRCW0805931RFKEA, ERJ-6ENF9310V, and RMCF0805FT931R carry AEC-Q200 automotive qualification. This certification indicates compliance with automotive reliability and quality standards. These parts are suitable for both automotive and general industrial applications. Non-automotive versions (RC0805FR-07931RL) are suitable for consumer and industrial applications.

Q: Are there any height restrictions for PCB assembly?

A: All substitute parts have seated heights between 0.50mm and 0.70mm. Standard 0805 component assembly processes accommodate this range without modification. Verify specific PCB design clearance requirements if height-critical applications are involved.

Q: Does MSL 1 rating apply to all substitutes?

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

Q: Which substitute offers the best supply chain availability?

A: ERJ-6ENF9310V (Panasonic) provides the highest inventory at 48144 pieces, offering superior supply security for high-volume production requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
