RCS2012F2152CS Equivalent & Substitute Parts

Part Overview

The RCS2012F2152CS is a 21.5 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part features anti-sulfur and moisture-resistant construction with a temperature coefficient of ±100ppm/°C. Currently in active production status with 1027 units available in inventory, this resistor is ROHS3 compliant and MSL 1 rated. Equivalent substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F2152CS are qualified based on the following criteria:

Electrical Parameters: Resistance value of 21.5 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical across all substitutes.

Mechanical Parameters: Package designation of 0805 (2012 Metric) with two terminations is mandatory for form-fit-function compatibility.

Environmental Specifications: Operating temperature range of -55°C to 155°C and temperature coefficient of ±100ppm/°C must be maintained.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to ensure regulatory and manufacturing process compatibility.

Composition: Thick film construction is consistent across all qualified substitutes.

The three identified substitute parts—CRCW080521K5FKEA (Vishay Dale), ERJ-6ENF2152V (Panasonic Electronic Components), and RC0805FR-0721K5L (YAGEO)—meet all mandatory electrical, mechanical, and compliance parameters. Variations in physical height and packaging format (Tape & Reel versus Cut Tape) do not affect electrical substitutability but may impact procurement and assembly logistics.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the RCS2012F2152CS based on matching electrical specifications and compliance certifications.

CRCW080521K5FKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification, indicating suitability for automotive and high-reliability applications. The lower seated height of 0.020" (0.50mm) compared to the main part may provide advantages in space-constrained PCB layouts. Inventory availability of 32,154 units supports consistent supply.

ERJ-6ENF2152V (Panasonic Electronic Components): This substitute also carries AEC-Q200 automotive qualification. The seated height of 0.028" (0.70mm) is slightly higher than the main part but remains within typical PCB assembly tolerances. Highest inventory availability at 47,641 units ensures supply continuity.

RC0805FR-0721K5L (YAGEO): This substitute features moisture-resistant construction matching the main part's environmental protection. The seated height of 0.024" (0.60mm) is intermediate between alternatives. Packaging in Cut Tape (CT) & Digi-Reel® format may suit applications requiring smaller order quantities. Inventory of 62,974 units provides robust availability.

Selection among substitutes should be based on procurement requirements, packaging format preferences, and supply chain considerations rather than electrical performance, as all parts are electrically equivalent.

Frequently Asked Questions (FAQ)

Q: Can CRCW080521K5FKEA replace RCS2012F2152CS in all applications?

A: Yes. Both parts share identical electrical specifications (21.5 kOhms ±1%, 0.125W), operate across -55°C to 155°C, and maintain ROHS3 compliance and MSL 1 rating. The AEC-Q200 qualification of the Vishay part indicates automotive-grade reliability. Physical height difference (0.020" versus 0.026") is negligible for standard PCB assembly.

Q: What is the significance of the height differences listed in the parameter comparison?

A: Seated height variations (0.020" to 0.028") reflect manufacturing tolerances and design differences between manufacturers but do not affect electrical performance. These differences are relevant only for applications with strict vertical clearance constraints or high-density PCB layouts. Standard PCB assembly processes accommodate these variations.

Q: Are the substitute parts suitable for automotive applications?

A: CRCW080521K5FKEA and ERJ-6ENF2152V carry AEC-Q200 certification, qualifying them for automotive use. RC0805FR-0721K5L does not list automotive qualification but meets all electrical and environmental specifications for general industrial applications.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only procurement, storage, and assembly logistics. RC0805FR-0721K5L in Cut Tape (CT) & Digi-Reel® format is electrically identical to Tape & Reel alternatives. Selection should be based on production volume and assembly equipment compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts—RCS2012F2152CS, CRCW080521K5FKEA, ERJ-6ENF2152V, and RC0805FR-0721K5L—are ROHS3 compliant and MSL 1 rated, ensuring regulatory compliance and compatibility with modern manufacturing processes.

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

A: Yes. All substitute parts are form-fit-function equivalents with identical electrical performance, temperature characteristics, and compliance certifications. No circuit redesign or validation is required for substitution.
