RC6432F2550CS Equivalent & Substitute Parts

Part Overview

The RC6432F2550CS is a 255 Ohm ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

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

• Electrical Specifications: Resistance value (255 Ohms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must be identical
• Package Compatibility: 2512 (6432 Metric) package with 2 terminations required for PCB footprint compatibility
• Environmental Ratings: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL 1 rating must be maintained
• Composition: Thick film construction specified

The identified substitute parts meet all these criteria. Additional certifications such as AEC-Q200 automotive qualification represent enhanced specifications beyond the base requirements and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2550CS (Samsung Electro-Mechanics) is the primary reference part with active production status. This part is suitable for new designs and ongoing production applications.

AC2512FK-07255RL (YAGEO) is an upgrade substitute with active product status. This part includes AEC-Q200 automotive qualification and moisture-resistant features, providing enhanced reliability for automotive and harsh environment applications while maintaining full electrical and mechanical equivalence.

ERJ-1TNF2550U (Panasonic Electronic Components) meets all electrical and mechanical substitution criteria but carries a "Not For New Designs" status. This part is suitable for legacy system maintenance, repair, and replacement applications where existing designs are already qualified to this component. New design implementations should prioritize the Samsung or YAGEO alternatives.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07255RL be used as a direct replacement for RC6432F2550CS?

A: Yes. Both parts share identical electrical specifications (255 Ohms ±1%, 1W), composition (thick film), package (2512), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance ratings (ROHS3, MSL 1). The AC2512FK-07255RL includes additional AEC-Q200 automotive certification, which does not prevent substitution.

Q: What is the difference between the three substitute parts?

A: All three parts are electrically and mechanically equivalent. The primary differences are manufacturer (Samsung, YAGEO, Panasonic), product status (RC6432F2550CS and AC2512FK-07255RL are active; ERJ-1TNF2550U is not for new designs), and certifications (AC2512FK-07255RL and ERJ-1TNF2550U include AEC-Q200). Dimensional tolerances vary slightly within acceptable PCB footprint compatibility.

Q: Are there packaging differences between these parts?

A: RC6432F2550CS is supplied in standard packaging. AC2512FK-07255RL and ERJ-1TNF2550U are supplied in Tape & Reel (TR) format. All three use the identical 2512 (6432 Metric) package footprint, ensuring PCB compatibility regardless of packaging format.

Q: Can ERJ-1TNF2550U be used in new product designs?

A: No. ERJ-1TNF2550U carries a "Not For New Designs" status. This part is restricted to legacy system support, repair, and replacement applications. New designs should use RC6432F2550CS or AC2512FK-07255RL.

Q: What does MSL 1 rating mean for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. These parts do not require special moisture control during storage or handling, simplifying logistics and inventory management.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC6432F2550CS, AC2512FK-07255RL, and ERJ-1TNF2550U are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
