Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F1871CS are qualified based on the following critical parameters that must match or remain within acceptable tolerances:

Mandatory Matching Parameters:

• Resistance value: 1.87 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Acceptable Variation Parameters:

• Height-seated maximum: Variations within 0.020" to 0.028" (0.50mm to 0.70mm) are acceptable due to manufacturing tolerances and do not affect circuit performance in standard applications
• Manufacturer and series designation: Different manufacturers produce functionally equivalent components

All identified substitute parts meet these criteria and are suitable for direct replacement in applications where the RC2012F1871CS is specified.

Parameter Comparison

Engineering Selection Recommendations

RC2012F1871CS (Samsung Electro-Mechanics) Primary selection for general-purpose applications. Active product status with moisture-resistant thick film construction. ROHS3 compliant. Suitable for consumer and industrial electronics where automotive qualification is not required.

ERJ-6ENF1871V (Panasonic Electronic Components) Direct substitute with automotive AEC-Q200 qualification. Identical electrical specifications and operating parameters. Recommended for automotive applications or where AEC-Q200 certification is specified. Higher inventory availability (95,512 pcs).

RC0805FR-071K87L (YAGEO) Direct substitute with moisture-resistant thick film composition matching the primary part. ROHS3 compliant. Lowest seated height (0.024" / 0.60mm) suitable for space-constrained PCB layouts. Significant inventory availability (57,198 pcs).

RMCF0805FT1K87 (Stackpole Electronics Inc) Direct substitute with automotive AEC-Q200 qualification. Identical seated height to primary part (0.026" / 0.65mm). Recommended for automotive applications requiring Stackpole component qualification.

CRCW08051K87FKEA (Vishay Dale) Direct substitute with automotive AEC-Q200 qualification. Lowest seated height profile (0.020" / 0.50mm) among all options. Recommended for high-density PCB applications or where Vishay Dale component qualification is required.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF1871V replace RC2012F1871CS in non-automotive applications? A: Yes. ERJ-6ENF1871V meets all electrical and mechanical specifications of RC2012F1871CS. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive applications.

Q: What is the significance of the height-seated maximum variation between parts? A: Height variations (0.020" to 0.028") fall within standard manufacturing tolerances for 0805 package resistors. These variations do not affect electrical performance or standard PCB assembly processes. Selection based on height is only necessary for applications with specific mechanical constraints such as ultra-low-profile designs.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant, matching the primary RC2012F1871CS component.

Q: Which substitute part should be selected for automotive applications? A: ERJ-6ENF1871V, RMCF0805FT1K87, and CRCW08051K87FKEA all carry AEC-Q200 automotive qualification. Selection among these three depends on manufacturer preference, inventory availability, and specific design constraints such as PCB height limitations.

Q: Is the Moisture Sensitivity Level identical across all parts? A: Yes. All parts including the primary RC2012F1871CS carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. All substitute parts are mechanically and electrically compatible with the RC2012F1871CS. They share identical 0805 package dimensions, resistance value, tolerance, power rating, and operating temperature range. PCB footprints and assembly processes remain unchanged.

Q: What is the difference between "Direct" and "Similar" substitute classifications? A: Direct substitutes (ERJ-6ENF1871V, RC0805FR-071K87L, RMCF0805FT1K87) are functionally equivalent with no distinguishing features. CRCW08051K87FKEA is classified as similar due to its lowest seated height profile, which may be advantageous in specific mechanical applications but does not affect electrical equivalence.
