RCS2012F36R5CS Equivalent & Substitute Parts

Part Overview

The RCS2012F36R5CS is a 36.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.125W (1/8W) in 0805 (2012 Metric) surface mount package. This component is classified as Active product status with anti-sulfur and moisture resistant construction. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are maintained across alternative manufacturers while preserving functional compatibility in target applications.

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F36R5CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Resistance value of 36.5 Ohms, tolerance of ±1%, power rating of 0.125W (1/8W), and temperature coefficient of ±100ppm/°C must be identical.

Mechanical Equivalence: Package designation 0805 (2012 Metric) with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and two terminations.

Environmental Equivalence: Operating temperature range of -55°C ~ 155°C, RoHS3 compliance, MSL rating of 1 (Unlimited), and REACH unaffected status.

Composition: Thick film construction is required for all substitutes.

All identified substitute parts meet these criteria without exception. Variations in seated height and specific feature sets (anti-sulfur vs. automotive AEC-Q200 certification) do not affect functional substitution within the specified parameter boundaries.

Engineering Selection Recommendations

All four parts listed—RCS2012F36R5CS (Samsung Electro-Mechanics), CRCW080536R5FKEA (Vishay Dale), ERJ-6ENF36R5V (Panasonic Electronic Components), and RC0805FR-0736R5L (YAGEO)—maintain Active product status and full compliance with ROHS3 and REACH requirements. Selection among these equivalents is determined by application-specific requirements and supply chain considerations rather than electrical or mechanical incompatibility.

CRCW080536R5FKEA and ERJ-6ENF36R5V carry AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications. RC0805FR-0736R5L and RCS2012F36R5CS provide moisture-resistant construction without automotive-specific certification. Seated height variations (0.020" to 0.028") are within standard PCB design tolerances for 0805 packages and do not restrict interchangeability in standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW080536R5FKEA replace RCS2012F36R5CS in non-automotive applications?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, package dimensions, and operating temperature range. The AEC-Q200 certification on CRCW080536R5FKEA does not restrict its use in non-automotive circuits.

Q: Are there differences in reliability between these substitute parts?

A: All parts share identical electrical specifications, temperature coefficients, and environmental ratings. Reliability differences, if any, are determined by manufacturer-specific failure rate data, which is not provided in the available specifications.

Q: Does the seated height variation affect PCB layout?

A: No. Seated height variations from 0.020" (0.50mm) to 0.028" (0.70mm) are within standard 0805 package tolerances and do not impact PCB design, reflow soldering, or component placement in standard surface mount assembly.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All substitute parts maintain identical footprint dimensions (0.079" L x 0.049" W), two-terminal configuration, and package designation (0805 / 2012 Metric). No PCB redesign is required for substitution.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry this rating, eliminating moisture sensitivity as a substitution constraint.

Q: Are there supply or inventory considerations for selection?

A: Inventory levels vary: CRCW080536R5FKEA (114,055 Pcs), ERJ-6ENF36R5V (100,940 Pcs), RC0805FR-0736R5L (19,749 Pcs), and RCS2012F36R5CS (705 Pcs). Supply availability may influence selection in high-volume production scenarios.
