Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F5113CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (511 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Compatibility: Package type (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and number of terminations (2) must be identical.

Environmental & Compliance: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL rating (1) must be maintained.

Composition: Thick film construction is required for all substitutes.

All four substitute parts listed meet these criteria and are therefore direct functional equivalents to the RCS2012F5113CS.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F5113CS based on matching electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

Automotive Applications: The CRCW0805511KFKEA (Vishay Dale), ERJ-6ENF5113V (Panasonic), and RMCF0805FT511K (Stackpole) carry AEC-Q200 automotive qualification ratings, making them suitable for automotive-grade circuit designs. The RC0805FR-07511KL (YAGEO) does not carry this certification.

General Industrial Applications: All parts, including the RC0805FR-07511KL, are suitable for non-automotive industrial and consumer applications.

Compliance & Certifications: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL rating 1 (unlimited moisture sensitivity level), matching the original RCS2012F5113CS specifications.

Physical Height Variation: Seated height ranges from 0.020" to 0.028" across all parts. In space-constrained PCB designs, the CRCW0805511KFKEA offers the lowest profile at 0.020" (0.50mm).

Inventory Availability: Substitute parts demonstrate varying stock levels, with ERJ-6ENF5113V (Panasonic) offering the highest inventory at 129,336 pieces.

Frequently Asked Questions (FAQ)

Q: Can the CRCW0805511KFKEA replace the RCS2012F5113CS in any application?

A: Yes, the CRCW0805511KFKEA is a direct electrical and mechanical equivalent. Both components share identical resistance (511 kOhms), tolerance (±1%), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The CRCW0805511KFKEA additionally carries AEC-Q200 automotive certification, making it suitable for automotive applications where the original part may not be specified.

Q: What is the difference between the substitute parts in terms of package compatibility?

A: All substitute parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). The only variation is seated height: CRCW0805511KFKEA (0.020" / 0.50mm), RC0805FR-07511KL (0.024" / 0.60mm), RCS2012F5113CS (0.026" / 0.66mm), RMCF0805FT511K (0.026" / 0.65mm), and ERJ-6ENF5113V (0.028" / 0.70mm). This variation does not affect PCB footprint compatibility but may be relevant in applications with strict height constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the RCS2012F5113CS.

Q: Which substitute part should be selected for automotive applications?

A: The CRCW0805511KFKEA (Vishay Dale), ERJ-6ENF5113V (Panasonic), and RMCF0805FT511K (Stackpole) all carry AEC-Q200 automotive qualification. Selection among these three should be based on availability, lead time, and specific design requirements. The RC0805FR-07511KL does not carry automotive certification and should not be used in automotive-grade designs unless explicitly approved by design engineering.

Q: Is the temperature coefficient specification identical across all parts?

A: Yes, all parts including the RCS2012F5113CS and all four substitutes specify ±100ppm/°C temperature coefficient, ensuring consistent thermal performance across the operating range of -55°C to 155°C.

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

A: Yes, all parts are mechanically and electrically interchangeable on the same PCB. The 0805 package footprint is standardized, and all parts have identical lead spacing and termination count (2 terminations). No PCB redesign is required when substituting between these parts.
