RC2012F28R7CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F28R7CS is a 28.7 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 and is RoHS3 compliant with MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F28R7CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 28.7 Ohms (exact match required)
• Tolerance: ±1% (precision class must match)
• Power Rating: 0.125W / 1/8W (thermal capability must equal or exceed)
• Package Type: 0805 (2012 Metric) (physical footprint must be identical)
• Composition: Thick Film (technology platform must match)
• Temperature Coefficient: ±100ppm/°C (stability specification must match)
• Operating Temperature Range: -55°C to 155°C (minimum range must be met or exceeded)
• RoHS Compliance: ROHS3 Compliant (regulatory status must match)

Acceptable Variation Parameters:

• Manufacturer identity (different manufacturers permitted)
• Height-Seated dimension (minor variations acceptable within standard tolerances)
• Series designation (manufacturer-specific nomenclature)
• Additional certifications (AEC-Q200 automotive rating is supplementary, not disqualifying)

All identified substitute parts meet these criteria and are electrically and mechanically interchangeable with the RC2012F28R7CS.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—RC0805FR-0728R7L (YAGEO), CRCW080528R7FKEA (Vishay Dale), and ERJ-6ENF28R7V (Panasonic)—are electrically and mechanically equivalent to the RC2012F28R7CS and are suitable for direct substitution in applications requiring a 28.7 Ohm ±1% 1/8W 0805 chip resistor.

Selection Basis:

All substitute parts maintain identical electrical specifications (resistance, tolerance, power rating, temperature coefficient, and operating temperature range) and are packaged in the same 0805 (2012 Metric) footprint. All parts are Active products with ROHS3 compliance and MSL Level 1 rating, ensuring regulatory alignment and unlimited shelf life.

The CRCW080528R7FKEA and ERJ-6ENF28R7V include AEC-Q200 automotive qualification, which is a supplementary certification that does not affect general-purpose application compatibility. These parts are suitable for applications requiring automotive-grade reliability.

Height-seated dimensions vary slightly among the substitute parts (0.020" to 0.028"), which falls within standard manufacturing tolerances for 0805 package components and does not affect PCB assembly compatibility or electrical performance.

Selection among the three substitutes may be based on availability, supply chain preference, or specific application requirements for automotive qualification. All parts are functionally interchangeable.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0728R7L be used as a direct replacement for RC2012F28R7CS?

A: Yes. The RC0805FR-0728R7L meets all mandatory electrical and mechanical parameters: 28.7 Ohm resistance, ±1% tolerance, 0.125W power rating, 0805 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL Level 1 rating. The parts are electrically and mechanically equivalent.

Q: What is the difference between the Samsung RC2012F28R7CS and the Vishay Dale CRCW080528R7FKEA?

A: Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is that CRCW080528R7FKEA includes AEC-Q200 automotive qualification, which is an additional certification for automotive applications. The height-seated dimension differs slightly (0.020" vs. 0.026"), but this variation is within standard 0805 package tolerances and does not affect compatibility.

Q: Are the Panasonic ERJ-6ENF28R7V and Samsung RC2012F28R7CS compatible in the same circuit?

A: Yes. The ERJ-6ENF28R7V is electrically and mechanically equivalent to the RC2012F28R7CS. Both parts have identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. The ERJ-6ENF28R7V also includes AEC-Q200 automotive qualification. The height-seated dimension is 0.028" compared to 0.026" for the Samsung part, which is within acceptable manufacturing tolerance for 0805 components.

Q: Do all substitute parts have the same moisture resistance rating?

A: All parts listed are thick film 0805 chip resistors with moisture-resistant construction and MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions. The moisture resistance feature is consistent across all parts.

Q: Can I use CRCW080528R7FKEA in a non-automotive application?

A: Yes. The CRCW080528R7FKEA is suitable for any application requiring a 28.7 Ohm ±1% 1/8W 0805 chip resistor. The AEC-Q200 automotive qualification is a supplementary certification that does not restrict use in general-purpose applications. The part meets all standard electrical and mechanical requirements.

Q: What is the significance of the different height-seated dimensions among the substitute parts?

A: The height-seated dimensions (0.020" to 0.028") represent minor manufacturing variations within the 0805 package specification. These variations do not affect PCB assembly compatibility, reflow soldering processes, or electrical performance. All parts are suitable for standard surface-mount assembly equipment.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts—RC0805FR-0728R7L, CRCW080528R7FKEA, and ERJ-6ENF28R7V—are ROHS3 compliant and REACH unaffected, matching the regulatory status of the RC2012F28R7CS.

Q: Which substitute part should I select if availability is the primary concern?

A: Selection should be based on current inventory levels from your supplier. According to provided data, ERJ-6ENF28R7V (Panasonic) has the highest inventory at 39,509 pieces, followed by CRCW080528R7FKEA (Vishay Dale) at 20,688 pieces, and RC0805FR-0728R7L (YAGEO) at 11,422 pieces. All parts are electrically and mechanically interchangeable.
