RC6432J243CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432J243CS is a 24 kOhms ±5% 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 requirements necessitate sourcing from alternative manufacturers while maintaining identical electrical and mechanical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432J243CS and RC2512JK-0724KL are Active status components suitable for direct substitution in applications requiring 24 kOhms ±5% 1W thick film resistors in the 2512 package format.

Compliance Verification: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial, automotive, and consumer electronics applications. The MSL 1 rating on both components eliminates moisture sensitivity concerns during standard storage and handling procedures.

Dimensional Compatibility: Physical dimensions between the two parts are within acceptable tolerances for standard PCB assembly processes. The RC2512JK-0724KL exhibits marginally tighter dimensional specifications (0.250" x 0.122" versus 0.248" x 0.126"), with seated height differences of 0.01mm (0.65mm versus 0.66mm), which remain within standard PCB design clearances.

Electrical Performance: Identical electrical specifications across resistance, tolerance, power rating, temperature coefficient, and operating temperature range ensure functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RC2512JK-0724KL replace RC6432J243CS in existing designs?

A: Yes. Both components share identical electrical specifications (24 kOhms ±5%, 1W, ±100ppm/°C, -55°C to 155°C), composition (thick film), and package format (2512/6432 Metric). Physical dimensions are within acceptable PCB assembly tolerances.

Q: Are there packaging differences between these parts?

A: The RC6432J243CS is supplied in standard packaging, while the RC2512JK-0724KL is supplied in Tape & Reel (TR) format. Both formats are compatible with automated assembly equipment. Tape & Reel packaging is standard for high-volume production environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC6432J243CS and RC2512JK-0724KL are ROHS3 compliant, REACH Unaffected, and carry MSL 1 ratings. They satisfy identical regulatory and environmental requirements.

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

A: The temperature coefficient defines resistance drift across the operating temperature range. At ±100ppm/°C, both parts maintain stable resistance values across -55°C to 155°C, with maximum drift of approximately 2% across the full temperature span. This specification is identical for both components.

Q: Are dimensional differences between the parts significant?

A: Dimensional variations (0.248" versus 0.250" length, 0.126" versus 0.122" width, 0.66mm versus 0.65mm height) are within standard PCB design tolerances and do not affect assembly compatibility or circuit performance.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 indicates no moisture sensitivity restrictions. Components can be stored and handled under standard warehouse conditions without requiring desiccant packaging or time-limited shelf life management.
