Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F2551CS is determined by strict alignment with the following critical parameters:

Electrical Specifications: Resistance value of 2.55 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use 0805 (2012 Metric) package format with 2 terminations to ensure PCB footprint compatibility and automated assembly compatibility.

Material Composition: Thick film construction is required to maintain electrical performance characteristics and thermal stability.

Environmental Specifications: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C ~ 155°C must be maintained. MSL 1 (Unlimited) rating ensures moisture resistance equivalent to the primary part.

Compliance Standards: ROHS3 compliance and REACH Unaffected status are mandatory for regulatory alignment.

The identified substitute parts meet all these criteria and are classified as either Direct equivalents or Similar alternatives based on feature alignment.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: RC0805FR-072K55L (YAGEO) is classified as a direct equivalent to RC2012F2551CS. This part maintains identical electrical and mechanical specifications with Active product status and full ROHS3 compliance. The primary distinction is the seated height maximum of 0.024" (0.60mm) compared to 0.026" (0.66mm) for the Samsung part, which remains within acceptable PCB assembly tolerances for 0805 package format.

Similar Alternatives with Enhanced Features: CRCW08052K55FKEA (Vishay Dale), ERJ-6ENF2551V (Panasonic), and RMCF0805FT2K55 (Stackpole) are classified as similar alternatives. These parts maintain all core electrical specifications and package compatibility while incorporating Automotive AEC-Q200 qualification. This additional certification provides enhanced reliability documentation suitable for automotive and high-reliability applications. Seated height variations (0.020" to 0.028") remain within standard 0805 package tolerances.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility with the primary part across global markets.

Inventory Availability: YAGEO RC0805FR-072K55L offers the highest inventory availability at 214,004 pieces, followed by Panasonic ERJ-6ENF2551V at 149,053 pieces, supporting extended procurement timelines and volume requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072K55L be used as a direct replacement for RC2012F2551CS?

A: Yes. RC0805FR-072K55L meets all electrical specifications (2.55 kOhms ±1%, 0.125W), operates within the identical temperature range (-55°C ~ 155°C), maintains ±100ppm/°C temperature coefficient, and uses the same 0805 package format. Both parts are ROHS3 compliant with MSL 1 rating. The 0.002" (0.06mm) difference in seated height is within standard 0805 package tolerances and does not affect PCB assembly compatibility.

Q: What is the difference between the Samsung part and the Automotive AEC-Q200 qualified alternatives?

A: The Samsung RC2012F2551CS is specified as moisture resistant thick film. The Vishay Dale CRCW08052K55FKEA, Panasonic ERJ-6ENF2551V, and Stackpole RMCF0805FT2K55 carry Automotive AEC-Q200 qualification in addition to moisture resistance. AEC-Q200 certification indicates enhanced reliability testing and qualification for automotive applications. All parts maintain identical core electrical and thermal specifications.

Q: Are all substitute parts suitable for the same PCB assembly process?

A: Yes. All substitute parts use 0805 (2012 Metric) package format with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and 2 terminations. Seated height variations (0.020" to 0.028") are within standard 0805 package tolerances and do not require PCB design modifications. All parts are supplied in Tape & Reel packaging compatible with standard SMD assembly equipment.

Q: Which substitute part offers the best supply chain availability?

A: YAGEO RC0805FR-072K55L provides the highest inventory level at 214,004 pieces in stock. Panasonic ERJ-6ENF2551V offers 149,053 pieces. Both parts support immediate procurement and extended volume requirements without supply constraints.

Q: Can substitute parts be mixed within the same PCB assembly?

A: Yes. All substitute parts meet identical electrical specifications, package format, and compliance requirements. Mixed sourcing of equivalent parts within a single PCB assembly does not introduce functional or reliability concerns. However, design documentation should reflect the approved substitute part list for traceability and future maintenance.

Q: What compliance certifications apply to all substitute parts?

A: All parts including the primary RC2012F2551CS are ROHS3 compliant and REACH Unaffected. CRCW08052K55FKEA, ERJ-6ENF2551V, and RMCF0805FT2K55 carry additional Automotive AEC-Q200 qualification. All parts are classified under ECCN EAR99 and HTSUS 8533.21.0030 for export and tariff purposes.
