Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F7872CS are qualified based on the following critical parameters that determine functional equivalence:

Electrical Parameters:

• Resistance value: 78.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package format: 0805 (2012 Metric) (exact match required)
• Physical dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 compliance (required)
• MSL 1 rating (required)
• Tape & Reel packaging format (required)

All substitute parts listed below meet these criteria. Variations in height-seated maximum and specific feature sets (anti-sulfur vs. automotive AEC-Q200 certification) do not affect functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F7872CS, CRCW080578K7FKEA, ERJ-6ENF7872V, and RC0805FR-0778K7L—are functionally equivalent for direct substitution based on matching electrical specifications, mechanical dimensions, and compliance certifications.

Selection Criteria Based on Provided Data:

CRCW080578K7FKEA (Vishay Dale): This substitute carries automotive AEC-Q200 certification, indicating qualification for automotive applications. It maintains the lowest seated height at 0.020" (0.50mm), which may be advantageous in space-constrained PCB layouts. Inventory availability is 14,605 pieces.

ERJ-6ENF7872V (Panasonic Electronic Components): This substitute also carries automotive AEC-Q200 certification. It has the highest seated height at 0.028" (0.70mm). Inventory availability is 38,067 pieces, representing the highest stock level among all substitutes.

RC0805FR-0778K7L (YAGEO): This substitute features moisture-resistant construction similar to the original RCS2012F7872CS. Seated height is 0.024" (0.60mm). Inventory availability is 44,188 pieces, the highest among all listed parts.

All parts are ROHS3 compliant, MSL 1 rated, and available in Tape & Reel packaging. Selection between these equivalents depends on application-specific requirements such as automotive qualification needs, PCB height constraints, or preferred supplier relationships. All parts maintain active production status.

Frequently Asked Questions (FAQ)

Q: Can CRCW080578K7FKEA replace RCS2012F7872CS in any application?

A: CRCW080578K7FKEA is electrically and mechanically equivalent to RCS2012F7872CS. Both parts share identical resistance value (78.7 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is that CRCW080578K7FKEA carries automotive AEC-Q200 certification, which is an additional qualification not present in the original part. Direct substitution is supported by matching specifications.

Q: What is the significance of the height-seated maximum variation between these parts?

A: Height-seated maximum values range from 0.020" (0.50mm) for CRCW080578K7FKEA to 0.028" (0.70mm) for ERJ-6ENF7872V. These variations reflect manufacturing tolerances within the 0805 package specification. For most applications, these differences are negligible. However, in PCB designs with extremely tight vertical clearance constraints or specific solder reflow profile requirements, the seated height should be verified against design specifications.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts—CRCW080578K7FKEA, ERJ-6ENF7872V, and RC0805FR-0778K7L—are supplied in Tape & Reel (TR) packaging, identical to the original RCS2012F7872CS. This ensures compatibility with automated assembly equipment and standard component handling processes.

Q: What does AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive qualification standard. CRCW080578K7FKEA and ERJ-6ENF7872V carry this certification, indicating these parts meet automotive industry reliability and performance requirements. The original RCS2012F7872CS does not carry this certification. If automotive qualification is required for your application, CRCW080578K7FKEA or ERJ-6ENF7872V are appropriate selections.

Q: Are all parts ROHS3 compliant?

A: All four parts—RCS2012F7872CS, CRCW080578K7FKEA, ERJ-6ENF7872V, and RC0805FR-0778K7L—are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. This ensures compatibility with modern manufacturing processes and environmental regulations.

Q: Which substitute has the highest inventory availability?

A: RC0805FR-0778K7L (YAGEO) has the highest inventory availability at 44,188 pieces, followed by ERJ-6ENF7872V (Panasonic) at 38,067 pieces, and CRCW080578K7FKEA (Vishay Dale) at 14,605 pieces. The original RCS2012F7872CS has 1,051 pieces in stock.
