RC6432F563CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F563CS is a 56 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and maintains a temperature coefficient of ±100ppm/°C. The part is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Equivalent and substitute parts are identified when component availability becomes limited, supply chain disruptions occur, or inventory optimization is required. Substitute components must maintain electrical equivalence across all critical parameters including resistance value, tolerance, power rating, and thermal characteristics, as well as mechanical compatibility within the specified package dimensions.

Engineering Selection Recommendations

The RC2512FK-0756KL manufactured by YAGEO is a direct electrical and mechanical equivalent to the RC6432F563CS. Selection between these components should be based on the following factors:

Availability and Lead Time: The YAGEO RC2512FK-0756KL currently maintains higher inventory levels (4680 Pcs) compared to the Samsung part (782 Pcs), making it suitable for applications where supply continuity is a priority.

Packaging Format: The Samsung RC6432F563CS is supplied in standard packaging, while the YAGEO RC2512FK-0756KL is available in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume considerations.

Compliance Certification: Both components maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory equivalence for applications subject to environmental and hazardous substance restrictions.

Thermal and Electrical Performance: Both parts deliver identical electrical performance across the specified operating temperature range with matching temperature coefficients, ensuring functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0756KL be used as a direct replacement for RC6432F563CS on existing PCBs?

A: Yes. Both components share identical electrical specifications (56 kOhms ±1%, 1W, ±100ppm/°C) and are packaged in the 2512 (6432 Metric) format. Dimensional variations (length 6.30mm vs 6.35mm, width 3.20mm vs 3.10mm) fall within standard PCB pad tolerances and do not affect board-level compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in resistance value (56 kOhms), tolerance (±1%), power rating (1W), package format (2512), composition (Thick Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Q: Are there any differences in moisture sensitivity between these parts?

A: No. Both the RC6432F563CS and RC2512FK-0756KL carry an MSL rating of 1 (Unlimited), indicating identical moisture sensitivity characteristics and identical storage and handling requirements.

Q: Does the Tape & Reel packaging of the YAGEO part affect electrical performance?

A: No. Packaging format (Tape & Reel vs standard packaging) affects only logistics, assembly process compatibility, and inventory management. Electrical and thermal performance remain identical.

Q: Are both parts suitable for high-reliability applications?

A: Both components are ROHS3 compliant and REACH Unaffected, meeting regulatory requirements for high-reliability applications. Selection should be based on specific application requirements, supply chain considerations, and assembly process compatibility.
