RC2012F1050CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F1050CS is a 105 Ohm ±1% 1/8W chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are required for component procurement, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the RC2012F1050CS are qualified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Mandatory Matching Parameters:

• Resistance value: 105 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Termination count: 2
• Packaging format: Tape & Reel (TR)

All identified substitute parts meet these parameters. Variations in seated height and specific feature sets (such as automotive AEC-Q200 qualification) do not disqualify substitution eligibility when core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—RC0805FR-07105RL (YAGEO), CRCW0805105RFKEA (Vishay Dale), and ERJ-6ENF1050V (Panasonic)—are qualified equivalents to the RC2012F1050CS based on matching electrical specifications, mechanical dimensions, and compliance certifications.

RC0805FR-07105RL (YAGEO): Direct equivalent with moisture-resistant thick film composition. Seated height of 0.024" (0.60mm) is within acceptable tolerance for standard PCB assembly. ROHS3 compliant with MSL 1 rating.

CRCW0805105RFKEA (Vishay Dale): Equivalent with additional automotive AEC-Q200 qualification. Lowest seated height at 0.020" (0.50mm) provides enhanced clearance for high-density PCB layouts. ROHS3 compliant with MSL 1 rating. Suitable for applications requiring automotive-grade reliability.

ERJ-6ENF1050V (Panasonic): Equivalent with automotive AEC-Q200 qualification. Seated height of 0.028" (0.70mm) represents maximum height among substitutes. ROHS3 compliant with MSL 1 rating. Suitable for applications requiring automotive-grade reliability.

All parts maintain Active product status and are available in Tape & Reel packaging format. Selection among substitutes depends on specific application requirements, PCB assembly constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07105RL replace RC2012F1050CS in any application?

A: Yes. RC0805FR-07105RL matches all mandatory electrical and mechanical parameters: 105 Ohms ±1%, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Seated height difference (0.024" vs 0.026") is within standard PCB assembly tolerances.

Q: What is the difference between CRCW0805105RFKEA and ERJ-6ENF1050V?

A: Both parts are electrically and mechanically equivalent to RC2012F1050CS and include automotive AEC-Q200 qualification. The primary difference is seated height: CRCW0805105RFKEA measures 0.020" (0.50mm) while ERJ-6ENF1050V measures 0.028" (0.70mm). Selection depends on PCB assembly height constraints and available space.

Q: Are automotive-qualified parts (AEC-Q200) interchangeable with non-automotive versions?

A: Yes, for electrical and mechanical compatibility. CRCW0805105RFKEA and ERJ-6ENF1050V include automotive AEC-Q200 qualification in addition to standard specifications. This additional qualification does not prevent use in non-automotive applications and may provide enhanced reliability margins.

Q: Does package format affect substitution?

A: No. All substitute parts use identical Tape & Reel (TR) packaging format and 0805 (2012 Metric) case size. Reel specifications and tape configuration are standardized across manufacturers for this package type.

Q: What tolerance variations exist among substitutes?

A: All substitute parts maintain ±1% tolerance specification, identical to RC2012F1050CS. No tolerance variation exists among qualified substitutes.

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

A: Yes. All parts share identical electrical specifications (105 Ohms ±1%, 0.125W, ±100ppm/°C), mechanical dimensions (0.079" L x 0.049" W), and environmental ratings (-55°C to 155°C, ROHS3, MSL 1). Seated height variations (0.020" to 0.028") fall within standard PCB assembly tolerances and do not affect interchangeability.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All substitute parts carry MSL 1 rating, matching the original RC2012F1050CS specification.
