RCS2012F1873CS Equivalent & Substitute Parts

Part Overview

The RCS2012F1873CS is a 187 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status and features anti-sulfur and moisture-resistant construction. The RCS2012F1873CS serves as a precision resistive element in general-purpose electronic applications requiring stable resistance values across extended temperature ranges. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1873CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (187 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must match exactly.

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

Compliance Requirements: RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) are mandatory for substitution.

Composition: Thick film construction is required.

All four identified substitute parts meet these criteria. Variations in height-seated maximum, packaging format (Tape & Reel versus Cut Tape), and optional automotive certifications do not disqualify substitution when core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are classified as Active product status and maintain full ROHS3 compliance and REACH unaffected status, matching the original RCS2012F1873CS specification.

CRCW0805187KFKEA (Vishay Dale): This substitute carries Automotive AEC-Q200 certification, providing enhanced reliability qualification for automotive applications. The seated height of 0.020" (0.50mm) is the lowest among all options, suitable for space-constrained PCB layouts.

ERJ-6ENF1873V (Panasonic Electronic Components): This substitute includes Automotive AEC-Q200 certification and offers the highest inventory availability (78,800 pieces). The seated height of 0.028" (0.70mm) is the maximum among all options.

RC0805FR-07187KL (YAGEO): This substitute is supplied in Cut Tape (CT) and Digi-Reel® packaging format, differing from the standard Tape & Reel format of other options. It features moisture-resistant construction matching the original part. Inventory availability is substantial at 168,808 pieces.

RMCF0805FT187K (Stackpole Electronics Inc): This substitute carries Automotive AEC-Q200 certification and maintains a seated height of 0.026" (0.65mm), closely matching the original component's 0.026" (0.66mm) specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805187KFKEA replace RCS2012F1873CS in non-automotive applications?

A: Yes. The CRCW0805187KFKEA meets all electrical and mechanical specifications required for substitution. Automotive AEC-Q200 certification is an additional qualification that does not restrict use in general-purpose applications.

Q: What is the significance of the height-seated maximum variation among substitute parts?

A: Height-seated maximum values range from 0.020" to 0.028" across the substitute options. This variation affects PCB clearance and component stacking in high-density layouts. Selection should be based on specific PCB design constraints. All values remain within acceptable mechanical tolerances for 0805 package specifications.

Q: Is RC0805FR-07187KL compatible with automated assembly equipment designed for Tape & Reel packaging?

A: RC0805FR-07187KL is supplied in Cut Tape (CT) and Digi-Reel® format rather than standard Tape & Reel. Compatibility with automated pick-and-place equipment depends on feeder configuration. Standard Tape & Reel alternatives (CRCW0805187KFKEA, ERJ-6ENF1873V, RMCF0805FT187K) provide direct compatibility with conventional assembly systems.

Q: Do all substitute parts maintain the same moisture resistance characteristics as the original RCS2012F1873CS?

A: All substitute parts are classified as Moisture Sensitivity Level 1 (Unlimited), matching the original specification. RC0805FR-07187KL explicitly lists moisture-resistant features. CRCW0805187KFKEA, ERJ-6ENF1873V, and RMCF0805FT187K do not specify moisture resistance in their feature descriptions, but all meet MSL 1 classification.

Q: Are there any compliance or certification differences that would affect component selection?

A: All substitute parts maintain ROHS3 compliance and REACH unaffected status identical to the original RCS2012F1873CS. Three substitutes (CRCW0805187KFKEA, ERJ-6ENF1873V, RMCF0805FT187K) carry additional Automotive AEC-Q200 certification. This certification is optional for general-purpose applications and does not create incompatibility.

Q: What inventory considerations should influence substitute part selection?

A: Inventory availability varies significantly: RC0805FR-07187KL (168,808 pieces), ERJ-6ENF1873V (78,800 pieces), CRCW0805187KFKEA (33,467 pieces), and RMCF0805FT187K (4,056 pieces). Selection based on supply chain requirements and lead time considerations is appropriate when all electrical and mechanical specifications are equivalent.
