RC6432F10R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F10R5CS is a 10.5 Ohm ±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 712 units available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope. Alternative sources provide design flexibility, supply chain redundancy, and access to parts with enhanced certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Resistance value: 10.5 Ohms (exact match)
• Tolerance: ±1% (minimum requirement)
• Power rating: 1W (minimum requirement)
• Temperature coefficient: ±100ppm/°C (maximum drift specification)
• Operating temperature range: -55°C to 155°C (minimum coverage)

Mechanical Equivalence Requirements:

• Package type: 2512 (6432 Metric) footprint
• Composition: Thick film construction
• Number of terminations: 2 (standard chip resistor configuration)

Compliance Requirements:

• RoHS3 compliance (mandatory for regulated applications)
• MSL 1 rating (unlimited moisture sensitivity level)

All identified substitutes meet these criteria. Additional certifications such as AEC-Q200 automotive qualification represent enhanced specifications beyond the base requirements and do not prevent substitution in non-automotive applications.

Engineering Selection Recommendations

Primary Selection (Active Production):

CRCW251210R5FKEG (Vishay Dale) is the recommended substitute for new designs. This part maintains full electrical and mechanical equivalence to the RC6432F10R5CS while offering AEC-Q200 automotive qualification. The part is in active production status with 2873 units in inventory and is supplied in Tape & Reel format suitable for automated assembly.

Alternative Selection (Legacy Applications):

ERJ-1TNF10R5U (Panasonic Electronic Components) provides equivalent electrical and mechanical performance with AEC-Q200 certification. However, this part carries a "Not For New Designs" product status designation. Use of this part is appropriate only for replacement, repair, or continuation of existing production lines where design changes are not feasible. Inventory availability is 9059 units.

Original Part (Active Production):

RC6432F10R5CS remains available in active production with 712 units in stock. Selection of the original part is appropriate when Samsung Electro-Mechanics sourcing is specified or preferred.

Frequently Asked Questions (FAQ)

Q: Can CRCW251210R5FKEG be used as a direct replacement for RC6432F10R5CS?

A: Yes. Both parts share identical electrical specifications (10.5 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and mechanical compatibility (2512 package, thick film construction, 2 terminations). The CRCW part includes AEC-Q200 automotive certification, which does not prevent use in non-automotive applications.

Q: What is the difference between the packaging formats listed?

A: RC6432F10R5CS is supplied in bulk packaging. CRCW251210R5FKEG and ERJ-1TNF10R5U are supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly. Bulk format is suitable for manual assembly or lower-volume applications. Both formats contain the same component.

Q: Why is ERJ-1TNF10R5U marked "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this part to legacy status and recommends alternative parts for new product development. The part remains available for existing applications and repairs. For new designs, CRCW251210R5FKEG is the preferred substitute.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC6432F10R5CS, CRCW251210R5FKEG, and ERJ-1TNF10R5U are all ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting regulatory requirements for most applications.

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

A: Yes. All three parts use the identical 2512 (6432 Metric) footprint with matching dimensions and termination configuration. PCB layout and assembly processes require no modification when substituting between these parts.

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

A: This specification defines the maximum resistance change per degree Celsius across the operating temperature range. All three parts share this specification, ensuring equivalent thermal stability and predictable performance across -55°C to 155°C.
