Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F5231CS are classified based on strict electrical and mechanical parameter matching. All identified substitutes maintain identical resistance value (5.23 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Physical dimensions remain consistent at 0.079" L x 0.049" W (2.00mm x 1.25mm) across all substitutes. All substitutes are RoHS3 compliant with MSL 1 rating and Tape & Reel packaging. Substitution eligibility is determined exclusively by these parameters. Differences in manufacturer, series designation, and optional certifications (such as AEC-Q200 automotive qualification) do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RC2012F5231CS (Samsung Electro-Mechanics), RC0805FR-075K23L (YAGEO), CRCW08055K23FKEA (Vishay Dale), and ERJ-6ENF5231V (Panasonic Electronic Components)—are functionally equivalent for applications requiring a 5.23 kOhms ±1% 0.125W 0805 thick film resistor. All parts maintain Active product status and RoHS3 compliance. Selection between these parts is based on availability, supply chain logistics, and application-specific requirements. CRCW08055K23FKEA and ERJ-6ENF5231V carry AEC-Q200 automotive qualification, which is relevant for automotive or high-reliability applications. Height variations (0.020" to 0.028" seated maximum) are within typical PCB design tolerances for 0805 components and do not affect functional performance in standard applications. Inventory availability: RC2012F5231CS (1003 pcs), RC0805FR-075K23L (117991 pcs), CRCW08055K23FKEA (24780 pcs), ERJ-6ENF5231V (167761 pcs).

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-075K23L replace RC2012F5231CS directly?

A: Yes. Both parts share identical electrical specifications (5.23 kOhms ±1%, 0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Physical dimensions are identical. Height difference (0.024" vs 0.026") is negligible for standard PCB applications.

Q: What is the difference between CRCW08055K23FKEA and ERJ-6ENF5231V?

A: Both parts are electrically and mechanically identical to the main part. The primary difference is manufacturer (Vishay Dale vs Panasonic). Both carry AEC-Q200 automotive qualification. Height specifications differ slightly (0.020" vs 0.028" seated maximum), but both remain within acceptable tolerances for 0805 package placement.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All four parts—RC2012F5231CS, RC0805FR-075K23L, CRCW08055K23FKEA, and ERJ-6ENF5231V—are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Which substitute has the lowest profile?

A: CRCW08055K23FKEA (Vishay Dale) has the lowest seated height at 0.020" (0.50mm). This may be relevant for space-constrained applications, though all parts are within standard 0805 specifications.

Q: Can I use an AEC-Q200 rated part in a non-automotive application?

A: Yes. AEC-Q200 certification indicates automotive-grade reliability and is a superset of standard specifications. Parts with AEC-Q200 qualification (CRCW08055K23FKEA and ERJ-6ENF5231V) are suitable for any application requiring the specified electrical and mechanical parameters.

Q: Are there any temperature coefficient differences between substitutes?

A: No. All four parts maintain identical temperature coefficient specification of ±100ppm/°C across the full operating range of -55°C ~ 155°C.

Q: What packaging format is used for all substitutes?

A: All parts are supplied in Tape & Reel (TR) format, consistent with standard SMD component distribution for high-volume manufacturing.
