RC6432J303CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432J303CS is a 30 kOhms ±5% 1W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This component is classified as Active product status with moisture-resistant construction and ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, power rating, tolerance, temperature coefficient) and mechanical compatibility (package type, physical dimensions, termination count). Alternative components may be required due to inventory availability, supply chain optimization, or performance upgrade requirements within allowable parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. The RC6432J303CS operates at 30 kOhms resistance with ±5% tolerance and 1W power dissipation in a 2512 package. Substitute parts must maintain these core electrical parameters: identical resistance value (30 kOhms), compatible power rating (1W minimum), matching package footprint (2512/6432 Metric), and equivalent operating temperature range (-55°C to 155°C).

Substitute parts are grouped into two categories:

Direct Equivalents maintain the original ±5% tolerance specification, ensuring drop-in replacement without circuit redesign.

Upgrade Substitutes feature improved ±1% tolerance while preserving all other electrical and mechanical parameters, providing enhanced accuracy for applications requiring tighter resistance control.

All identified substitutes comply with ROHS3 and maintain MSL 1 rating, confirming compatibility with standard manufacturing and storage conditions.

Parameter Comparison

Engineering Selection Recommendations

RC2512JK-0730KL (YAGEO Direct Equivalent)

This part provides direct substitution for RC6432J303CS with identical electrical specifications: 30 kOhms ±5% tolerance, 1W power rating, and ±100 ppm/°C temperature coefficient. Physical dimensions (6.35mm L × 3.10mm W) are within acceptable tolerance of the original component. ROHS3 compliance and MSL 1 rating confirm regulatory and manufacturing compatibility. This substitute is suitable for applications where the original ±5% tolerance specification is maintained and inventory replenishment is required.

RC2512FK-0730KL (YAGEO Upgrade Substitute)

This part upgrades tolerance performance to ±1% while maintaining all other electrical and mechanical parameters. Identical 1W power rating, ±100 ppm/°C temperature coefficient, and 2512 package footprint ensure mechanical and thermal compatibility. ROHS3 compliance and MSL 1 rating are preserved. Selection of this upgrade substitute is appropriate for circuits requiring improved resistance accuracy without redesign, provided the application tolerates the tighter tolerance specification.

RMCF2512FT30K0 (Stackpole Automotive Substitute)

This part matches core electrical specifications (30 kOhms ±1%, 1W, ±100 ppm/°C) and package type (2512). Physical dimensions (6.30mm L × 3.20mm W) align with original component specifications. Automotive AEC-Q200 qualification provides additional reliability assurance for demanding environments. ROHS3 compliance and MSL 1 rating are maintained. This substitute is applicable for applications requiring automotive-grade reliability or where Stackpole component qualification is specified.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-0730KL replace RC6432J303CS in all applications?

A: Yes. RC2512JK-0730KL maintains identical electrical specifications (30 kOhms ±5%, 1W, ±100 ppm/°C) and package footprint (2512). Physical dimensions are within acceptable tolerance. Both components are ROHS3 compliant with MSL 1 rating. Direct substitution is valid without circuit modification.

Q: What is the difference between the YAGEO direct equivalent and upgrade substitute?

A: RC2512JK-0730KL (direct equivalent) maintains ±5% tolerance matching the original specification. RC2512FK-0730KL (upgrade substitute) provides ±1% tolerance for improved accuracy. All other parameters—resistance value, power rating, temperature coefficient, package, and compliance ratings—are identical. Selection depends on circuit tolerance requirements.

Q: Is RMCF2512FT30K0 suitable for non-automotive applications?

A: Yes. RMCF2512FT30K0 meets all electrical and mechanical requirements for standard applications. The Automotive AEC-Q200 qualification represents additional quality assurance and does not restrict use in non-automotive circuits. This part is compatible with any application accepting the original RC6432J303CS specifications.

Q: Are there physical dimension differences between these substitutes?

A: Minor variations exist within acceptable tolerance. RC6432J303CS and RMCF2512FT30K0 share identical length (6.30mm) and width (3.20mm). RC2512JK-0730KL and RC2512FK-0730KL measure 6.35mm L × 3.10mm W. All variants fit the 2512 package footprint with standard PCB pad layouts. Height differences (0.65mm to 0.70mm seated) are negligible for standard assembly processes.

Q: Do all substitutes maintain the same moisture resistance rating?

A: Yes. All identified substitutes are thick film composition with moisture-resistant construction and MSL 1 (Unlimited) rating. Storage and handling requirements are identical to the original RC6432J303CS component.

Q: Which substitute should be selected for cost optimization?

A: Selection is based on inventory availability and application requirements, not cost. RC2512JK-0730KL (direct equivalent) is appropriate for standard tolerance applications. RC2512FK-0730KL (upgrade) is selected when ±1% accuracy is required. RMCF2512FT30K0 is chosen for automotive-qualified applications. All three are valid substitutes within their respective parameter specifications.
