RC6432F4871CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F4871CS is a 4.87 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film resistor features moisture resistance and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with 989 units available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package category. Alternative sources provide equivalent performance for applications requiring component availability, supply chain flexibility, or specific certification requirements such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F4871CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 4.87 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence Requirements:

• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected status

All identified substitute parts meet these criteria. Differences in physical dimensions (length, width, height) within the 2512 package specification, packaging format (Tape & Reel vs. bulk), and additional certifications (such as AEC-Q200) do not affect functional substitutability but may influence application suitability and procurement logistics.

Engineering Selection Recommendations

RC6432F4871CS (Samsung Electro-Mechanics) — Primary Selection

The RC6432F4871CS maintains active production status and is recommended as the primary component choice. This part is currently in stock with 989 units available. The moisture-resistant feature provides enhanced reliability in humid environments. Selection of this part ensures continuity with established supply chains and design validation history.

CRCW25124K87FKEG (Vishay Dale) — Preferred Substitute

The CRCW25124K87FKEG is functionally equivalent and maintains active production status. This part carries automotive AEC-Q200 certification, which qualifies it for automotive and high-reliability applications. Inventory availability is substantial at 10,541 units. The Tape & Reel packaging format supports automated assembly processes. This substitute is suitable for new designs and applications requiring automotive-grade components.

ERJ-1TNF4871U (Panasonic Electronic Components) — Legacy Substitute

The ERJ-1TNF4871U is electrically and mechanically equivalent but carries a "Not For New Designs" product status designation. This part is suitable only for replacement, repair, or maintenance of existing assemblies. Inventory availability is 3,435 units. Automotive AEC-Q200 certification is present. New design implementations should not incorporate this part number.

Frequently Asked Questions (FAQ)

Q: Can CRCW25124K87FKEG replace RC6432F4871CS in existing designs?

A: Yes. Both parts share identical electrical specifications (4.87 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and are packaged in the 2512 (6432 Metric) form factor. Physical dimensions vary slightly within package tolerance (length 6.30mm, width 3.15mm vs. 3.20mm; height 0.70mm vs. 0.66mm), which does not affect circuit performance or PCB layout compatibility. The CRCW25124K87FKEG includes automotive AEC-Q200 certification, providing additional qualification for demanding applications.

Q: What is the difference between the Samsung and Vishay parts?

A: The RC6432F4871CS emphasizes moisture resistance as a primary feature. The CRCW25124K87FKEG emphasizes automotive AEC-Q200 qualification. Both achieve MSL Level 1 (Unlimited) moisture sensitivity rating. The Vishay part is supplied in Tape & Reel format, optimizing for high-volume automated assembly. The Samsung part inventory status and specific moisture-resistant formulation may be preferred for applications in high-humidity environments where the additional feature provides documented performance assurance.

Q: Why is ERJ-1TNF4871U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has transitioned this part number to end-of-life or obsolescence management. While the part remains electrically and mechanically equivalent and is currently in inventory (3,435 units), it is designated for replacement and repair applications only. New product designs should utilize RC6432F4871CS or CRCW25124K87FKEG to ensure long-term supply continuity and manufacturer support.

Q: Are there packaging format differences that affect compatibility?

A: The RC6432F4871CS is supplied in standard packaging format. The CRCW25124K87FKEG and ERJ-1TNF4871U are supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly and high-volume production. Standard packaging may be preferred for manual assembly or low-volume applications. Both formats contain electrically identical components; the difference is logistical and manufacturing-process related.

Q: Do all three parts meet RoHS and REACH compliance?

A: Yes. All three parts are ROHS3 Compliant and carry REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8533.21.0030. Compliance documentation is equivalent across all three options.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient of ±100ppm/°C specifies the maximum change in resistance value per degree Celsius across the operating temperature range (-55°C to 155°C). This specification is identical across all three parts. For a 4.87 kOhm resistor, this translates to a maximum resistance change of approximately ±77.6 Ohms across the full temperature range. This specification is standard for thick film chip resistors in this power and tolerance class and does not differentiate the substitute options.
