Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2612CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 26.1 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 ~ 155°C (exact match required)

Mechanical Parameters:

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

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All four substitute parts listed below meet these criteria and are therefore direct functional equivalents of the RCS2012F2612CS.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F2612CS and maintain Active product status with full ROHS3 compliance and REACH Unaffected designation.

CRCW080526K1FKEA (Vishay Dale): This substitute incorporates Automotive AEC-Q200 qualification, providing enhanced reliability for automotive applications. The seated height of 0.020" (0.50mm) is the lowest among all options, which may be advantageous for space-constrained PCB layouts.

ERJ-6ENF2612V (Panasonic Electronic Components): This substitute features Automotive AEC-Q200 qualification and is available in the highest inventory quantity (182,200 pcs). The packaging format includes Cut Tape and Digi-Reel options in addition to standard reel formats. The seated height of 0.028" (0.70mm) is the maximum among all options.

RC0805FR-0726K1L (YAGEO): This substitute provides moisture-resistant construction without automotive qualification. The seated height of 0.024" (0.60mm) represents a mid-range profile. Inventory availability is substantial at 31,832 pcs.

RMCF0805FT26K1 (Stackpole Electronics Inc): This substitute includes Automotive AEC-Q200 qualification with a seated height of 0.026" (0.65mm), matching the original RCS2012F2612CS specification. Inventory availability is 33,132 pcs.

Selection among these equivalents should be based on application requirements, packaging preferences, and supply chain considerations rather than electrical performance, as all parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can CRCW080526K1FKEA replace RCS2012F2612CS in all applications?

A: Yes. Both parts share identical electrical specifications (26.1 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). The primary difference is the seated height (0.020" vs 0.026"), which is within acceptable PCB assembly tolerances for standard 0805 components.

Q: What is the difference between the packaging formats offered?

A: RCS2012F2612CS, CRCW080526K1FKEA, RC0805FR-0726K1L, and RMCF0805FT26K1 are supplied in Tape & Reel (TR) format. ERJ-6ENF2612V is available in Cut Tape (CT) and Digi-Reel® formats. All formats are compatible with standard SMD pick-and-place equipment; format selection depends on production volume and assembly line configuration.

Q: Are the automotive-qualified substitutes (CRCW080526K1FKEA, ERJ-6ENF2612V, RMCF0805FT26K1) required for non-automotive applications?

A: No. Automotive AEC-Q200 qualification is not required for non-automotive applications. The RCS2012F2612CS and RC0805FR-0726K1L are suitable for general industrial and consumer electronics applications. AEC-Q200 qualification provides additional process controls and reliability testing but is not necessary unless the application specifically requires automotive-grade components.

Q: What is the significance of the seated height variations among these parts?

A: Seated height variations (0.020" to 0.028") reflect manufacturing tolerances and construction differences among manufacturers. All values remain within the 0805 package specification and are compatible with standard PCB assembly processes. Height differences do not affect electrical performance or mechanical fit in standard 0805 footprints.

Q: Can these substitutes be used interchangeably in existing designs?

A: Yes. All substitute parts are direct functional equivalents with identical electrical parameters, package dimensions, and compliance certifications. No design modifications are required for substitution. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: Which substitute offers the best inventory availability?

A: ERJ-6ENF2612V (Panasonic Electronic Components) offers the highest inventory level at 182,200 pcs. RMCF0805FT26K1 (Stackpole) and CRCW080526K1FKEA (Vishay Dale) provide 33,132 pcs and 34,373 pcs respectively. RC0805FR-0726K1L (YAGEO) is available with 31,832 pcs.

Q: Are all these parts RoHS3 compliant?

A: Yes. All parts listed—RCS2012F2612CS, CRCW080526K1FKEA, ERJ-6ENF2612V, RC0805FR-0726K1L, and RMCF0805FT26K1—are ROHS3 Compliant with REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited).
