Equivalent & Substitute Parts for RCS2012F28R0CS

Part Overview

The RCS2012F28R0CS is a 28 Ohm ±1% 0.125W thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component is classified as Active product status and is supplied in Tape & Reel packaging. The part features anti-sulfur and moisture-resistant construction, making it suitable for general industrial and consumer applications requiring stable resistance performance across extended temperature ranges.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and environmental compliance certifications. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F28R0CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 28 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory)
• REACH Status: REACH Unaffected (mandatory)

All substitute parts listed below meet these criteria. Variations in physical dimensions (height, length, width) within standard tolerances do not affect substitutability, as these fall within normal manufacturing variation for the 0805 package specification.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F28R0CS, CRCW080528R0FKEA, ERJ-6ENF28R0V, and RC0805FR-0728RL—are electrically and mechanically equivalent and meet identical compliance requirements. Selection among these parts should be based on:

Availability and Lead Time: ERJ-6ENF28R0V (Panasonic) currently maintains the highest inventory level at 134,610 pieces, followed by CRCW080528R0FKEA (Vishay Dale) at 4,870 pieces, RC0805FR-0728RL (YAGEO) at 9,077 pieces, and RCS2012F28R0CS (Samsung) at 795 pieces.

Automotive Qualification: CRCW080528R0FKEA and ERJ-6ENF28R0V carry AEC-Q200 automotive qualification ratings. RCS2012F28R0CS and RC0805FR-0728RL do not list this certification.

Environmental Features: RCS2012F28R0CS specifies anti-sulfur construction in addition to moisture resistance. CRCW080528R0FKEA and ERJ-6ENF28R0V specify automotive AEC-Q200 qualification. RC0805FR-0728RL specifies moisture resistance only.

All parts are Active product status with ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, confirming suitability for current and future regulatory environments.

Frequently Asked Questions (FAQ)

Q: Can CRCW080528R0FKEA replace RCS2012F28R0CS in any application?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (28 Ohms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package (0805). Both are ROHS3 compliant with MSL 1 rating. CRCW080528R0FKEA includes AEC-Q200 automotive qualification, which RCS2012F28R0CS does not specify.

Q: What is the difference between ERJ-6ENF28R0V and RC0805FR-0728RL?

A: Both parts meet identical electrical and mechanical specifications. ERJ-6ENF28R0V (Panasonic) carries AEC-Q200 automotive qualification and has a maximum seated height of 0.028" (0.70mm). RC0805FR-0728RL (YAGEO) does not list automotive qualification and has a maximum seated height of 0.024" (0.60mm). Both are suitable for general industrial applications.

Q: Are there any dimensional differences that affect PCB layout?

A: All parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated heights vary slightly: RCS2012F28R0CS (0.026"), CRCW080528R0FKEA (0.020"), ERJ-6ENF28R0V (0.028"), and RC0805FR-0728RL (0.024"). These variations fall within standard 0805 package tolerances and do not require PCB layout modification.

Q: Which part should be selected for automotive applications?

A: CRCW080528R0FKEA and ERJ-6ENF28R0V both carry AEC-Q200 automotive qualification. RCS2012F28R0CS and RC0805FR-0728RL do not specify this certification and should not be used in applications requiring automotive-grade components.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All four parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts are ROHS3 compliant and REACH Unaffected, confirming compliance with current environmental regulations.
