RCS2012F2373CS Equivalent & Substitute Parts Reference

Part Overview

The RCS2012F2373CS is a 237 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 part is RoHS3 compliant with MSL 1 rating, suitable for general industrial and consumer applications requiring stable resistance values across extended temperature ranges.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization requires alternative sourcing, or when design specifications permit equivalent components from qualified manufacturers meeting identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F2373CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 237 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 Compliant (required)
• MSL 1 rating (required)
• Packaging: Tape & Reel (TR) (required)

All four substitute parts listed meet these criteria without exception. Substitution is valid for direct board-level replacement without circuit redesign or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F2373CS and are suitable for direct replacement in applications where the original part is unavailable.

CRCW0805237KFKEA (Vishay Dale): This substitute carries Automotive AEC-Q200 qualification, providing enhanced reliability documentation for automotive and mission-critical applications. Inventory availability is 14,230 units. Height-seated maximum is 0.020" (0.50mm), the lowest profile among all options.

ERJ-6ENF2373V (Panasonic Electronic Components): This substitute carries Automotive AEC-Q200 qualification and offers the highest inventory availability at 72,606 units. Height-seated maximum is 0.028" (0.70mm). The ERJ-6EN series provides consistent supply chain access.

RC0805FR-07237KL (YAGEO): This substitute features moisture-resistant construction matching the original part's environmental protection. Inventory availability is 232,680 units, the highest among all options. Height-seated maximum is 0.024" (0.60mm). The RC_L series is widely distributed in global supply chains.

RMCF0805FT237K (Stackpole Electronics Inc): This substitute carries Automotive AEC-Q200 qualification. Inventory availability is 7,771 units. Height-seated maximum is 0.026" (0.65mm), matching the original part specification.

Selection among these substitutes should be based on supply chain availability, inventory requirements, and application-specific certifications (AEC-Q200 for automotive use cases).

Frequently Asked Questions (FAQ)

Q: Can CRCW0805237KFKEA replace RCS2012F2373CS in any application?

A: Yes. Both parts share identical electrical specifications (237 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), identical package (0805 / 2012 Metric), identical composition (thick film), and identical compliance ratings (RoHS3, MSL 1). Direct substitution is valid without circuit modification.

Q: What is the difference between the substitute parts?

A: All substitute parts meet identical electrical and mechanical specifications. Differences exist only in manufacturer identity, AEC-Q200 automotive qualification status (Vishay Dale, Panasonic, and Stackpole carry this; YAGEO does not), physical height variation (0.020" to 0.028" seated maximum), and inventory availability. These differences do not affect electrical performance or board-level compatibility.

Q: Are the AEC-Q200 qualified parts (CRCW0805237KFKEA, ERJ-6ENF2373V, RMCF0805FT237K) required for non-automotive applications?

A: No. AEC-Q200 qualification is an additional quality assurance certification applicable to automotive and high-reliability applications. For general industrial and consumer applications, all four substitutes are equivalent. The original RCS2012F2373CS does not carry AEC-Q200 qualification.

Q: Can height differences affect PCB assembly?

A: Height variations among substitutes range from 0.020" to 0.028" (0.50mm to 0.70mm seated maximum). These differences are within standard SMD assembly tolerances and do not affect reflow soldering, wave soldering, or component placement on standard PCB designs. Height differences are not a substitution barrier.

Q: Which substitute offers the best supply chain availability?

A: RC0805FR-07237KL (YAGEO) offers the highest inventory at 232,680 units. ERJ-6ENF2373V (Panasonic) provides 72,606 units. Both represent strong supply chain positions for high-volume procurement.

Q: Is the anti-sulfur feature of the original part critical for substitution?

A: The original RCS2012F2373CS specifies anti-sulfur and moisture-resistant features. RC0805FR-07237KL (YAGEO) explicitly includes moisture-resistant construction. CRCW0805237KFKEA, ERJ-6ENF2373V, and RMCF0805FT237K do not list anti-sulfur specifications in provided data. For applications requiring anti-sulfur protection, RC0805FR-07237KL is the preferred substitute.

Q: Are all parts RoHS3 compliant?

A: Yes. All five parts (original and four substitutes) are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and regulatory requirements.
