Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2672CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 26.7 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Critical):

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance & Environmental (Required):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Composition: Thick Film

All identified substitute parts meet these core parameters. Additional features such as automotive AEC-Q200 rating or anti-sulfur characteristics represent enhanced specifications that do not prevent substitution but indicate application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F2672CS based on matching electrical and mechanical specifications. Selection among these alternatives is determined by application requirements and supply chain considerations:

CRCW080526K7FKEA (Vishay Dale): This substitute incorporates automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. Height specification of 0.020" (0.50mm) represents the lowest profile among alternatives, beneficial for space-constrained PCB layouts.

ERJ-6ENF2672V (Panasonic Electronic Components): This substitute includes automotive AEC-Q200 rating and offers the highest inventory availability (77,889 pcs). Height specification of 0.028" (0.70mm) is the maximum among alternatives and should be verified against PCB clearance requirements.

RC0805FR-0726K7L (YAGEO): This substitute features moisture-resistant characteristics matching the original RCS2012F2672CS specification. Height specification of 0.024" (0.60mm) provides mid-range profile. Inventory availability is highest at 140,194 pcs.

RMCF0805FT26K7 (Stackpole Electronics Inc): This substitute includes automotive AEC-Q200 qualification with height specification of 0.026" (0.65mm), matching the original component height. Suitable for automotive and general industrial applications.

All substitutes maintain ROHS3 compliance, MSL 1 rating, and Active product status. Height variations across alternatives require verification against specific PCB assembly constraints and solder reflow profiles.

Frequently Asked Questions (FAQ)

Q: Can CRCW080526K7FKEA replace RCS2012F2672CS in any application?

A: CRCW080526K7FKEA meets all electrical and mechanical specifications for direct substitution. The automotive AEC-Q200 qualification represents an enhanced feature that does not prevent substitution in general-purpose applications. Height difference of 0.006" (0.16mm) is negligible for standard PCB assembly processes.

Q: What is the significance of the height variations listed in the parameter comparison?

A: Height specifications (0.020" to 0.028") represent maximum seated heights after solder reflow. These variations are within standard PCB assembly tolerances for 0805 package components. Verification is required only for applications with critical clearance constraints, such as stacked component configurations or confined assembly spaces.

Q: Are all substitute parts suitable for high-temperature applications?

A: All substitute parts, including RCS2012F2672CS, operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. Selection among alternatives is not differentiated by temperature performance.

Q: Does the absence of AEC-Q200 rating on RC0805FR-0726K7L and RCS2012F2672CS limit their use?

A: AEC-Q200 rating is an automotive qualification that indicates enhanced reliability testing. Its absence does not prevent use in automotive applications but indicates the component has not undergone automotive-specific qualification testing. Selection depends on application requirements and customer specifications.

Q: How do moisture-resistant features affect substitution decisions?

A: Both RCS2012F2672CS and RC0805FR-0726K7L explicitly specify moisture-resistant characteristics. All four substitutes maintain MSL 1 (Unlimited) rating, indicating equivalent moisture sensitivity performance. Moisture-resistant features represent material composition enhancements that do not affect electrical or mechanical compatibility.

Q: Can these substitutes be used interchangeably on the same PCB assembly?

A: Yes, all substitute parts are mechanically and electrically interchangeable on standard PCB layouts. Height variations are within assembly process tolerances. Mixed component sourcing from multiple manufacturers is acceptable provided all parts meet the specified electrical and mechanical parameters.
