Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432J622CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (6.2 kOhms), tolerance (±5%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package format must be 2512 (6432 Metric) to ensure PCB footprint compatibility and assembly process alignment. Physical dimensions and termination count (2) must match or fall within acceptable manufacturing tolerances.

Compliance Parameters: RoHS3 compliance and MSL 1 rating are mandatory for regulatory and environmental requirements. REACH unaffected status ensures no restricted substance concerns.

Composition: Thick film construction with moisture-resistant properties must be maintained to preserve electrical stability and reliability characteristics.

The identified substitute RC2512JK-076K2L from YAGEO meets all substitution criteria across these parameter categories.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-076K2L be used as a direct replacement for RC6432J622CS?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 6.2 kOhms ±5% 1W rating, 2512 package format, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and identical compliance certifications. PCB footprint and assembly compatibility are maintained.

Q: What are the dimensional differences between these parts?

A: RC6432J622CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm) with maximum seated height of 0.026" (0.66mm). RC2512JK-076K2L measures 0.250" L x 0.122" W (6.35mm x 3.10mm) with maximum seated height of 0.026" (0.65mm). These variations fall within standard 2512 package tolerances and do not affect PCB layout or assembly.

Q: Are there any moisture sensitivity concerns with either part?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.

Q: Which part should be selected for high-volume automated assembly?

A: RC2512JK-076K2L is available in Tape & Reel (TR) packaging, which is optimized for automated pick-and-place assembly processes. RC6432J622CS standard packaging may require manual handling or reel conversion for automated lines.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both RC6432J622CS and RC2512JK-076K2L are ROHS3 compliant and REACH unaffected, satisfying current environmental and hazardous substance regulations for electronics manufacturing and distribution.

Q: What is the temperature coefficient significance for circuit design?

A: Both parts maintain ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. This specification defines resistance value drift in response to temperature changes and is critical for precision analog circuits, measurement applications, and temperature-sensitive networks.
