RC2012F2550CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F2550CS is a 255 Ohm ±1% 1/8W chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F2550CS are qualified based on strict equivalence of the following parameters:

Electrical Equivalence Criteria:

• Resistance value: 255 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence Criteria:

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

Compliance Equivalence Criteria:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH unaffected status
• ECCN: EAR99
• HTSUS: 8533.21.0030

All identified substitute parts maintain these core parameters. Variations in seated height and specific feature sets (moisture resistant vs. automotive AEC-Q200) do not affect functional substitutability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed maintain full electrical and mechanical equivalence for the 255 Ohm ±1% 1/8W 0805 resistor specification. Selection among these alternatives is determined by availability, supply chain requirements, and application-specific compliance needs.

RC0805FR-07255RL (YAGEO): Direct substitute with moisture-resistant composition matching the original specification. Seated height of 0.024" (0.60mm) is within acceptable PCB assembly tolerances.

CRCW0805255RFKEA (Vishay Dale): Qualified substitute with automotive AEC-Q200 rating. Lowest seated height at 0.020" (0.50mm) provides additional clearance margin in space-constrained layouts. Suitable for applications requiring automotive-grade reliability.

ERJ-6ENF2550V (Panasonic): Qualified substitute with automotive AEC-Q200 rating. Highest seated height at 0.028" (0.70mm) remains within standard PCB assembly specifications. Highest inventory availability (174,609 pcs) supports extended production runs.

All parts carry ROHS3 compliance, unlimited MSL rating, and identical electrical performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07255RL replace RC2012F2550CS in all applications?

A: Yes. Both parts share identical electrical specifications (255 Ohms ±1%, 0.125W, ±100ppm/°C), mechanical dimensions (0.079" x 0.049"), and environmental ratings (MSL 1, ROHS3). The 0.002" difference in seated height (0.024" vs. 0.026") is within standard PCB assembly tolerances.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: Both feature sets are compatible substitutes. Moisture-resistant variants (RC2012F2550CS, RC0805FR-07255RL) are optimized for general industrial applications. Automotive AEC-Q200 variants (CRCW0805255RFKEA, ERJ-6ENF2550V) meet additional automotive reliability and qualification standards. Selection depends on application requirements, not electrical performance.

Q: Are seated height variations significant for PCB assembly?

A: Seated height variations range from 0.020" to 0.028" across all qualified substitutes. These differences are within standard surface-mount assembly tolerances and do not affect reflow soldering, wave soldering, or component placement accuracy on standard PCB equipment.

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

A: Yes. All substitute parts maintain identical footprint (0805), electrical performance (255 Ohms ±1%), power rating (0.125W), and operating temperature range (-55°C to 155°C). No design modifications are required for substitution.

Q: Which substitute offers the best supply availability?

A: ERJ-6ENF2550V (Panasonic) provides the highest inventory level at 174,609 pcs. RC0805FR-07255RL (YAGEO) offers 40,637 pcs, and CRCW0805255RFKEA (Vishay Dale) provides 21,827 pcs. Availability should be verified with current supplier inventory at time of procurement.

Q: Are all parts suitable for lead-free soldering?

A: Yes. All parts are ROHS3 compliant, indicating compatibility with lead-free soldering processes and RoHS-restricted substance requirements.
