Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2800CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 280 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match or wider)

Mechanical Compatibility Requirements:

• Package classification: 2512 (6432 Metric) footprint
• Composition: Thick film construction
• Moisture resistance: Required feature
• Termination count: 2 terminations

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL 1 rating required
• REACH unaffected status

The RC2512FK-07280RL from YAGEO meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

RC6432F2800CS (Samsung Electro-Mechanics) is the primary specification. This part maintains active production status with established supply availability (792 pieces in stock). Full ROHS3 compliance and MSL 1 rating confirm suitability for standard industrial and commercial applications without moisture sensitivity constraints.

RC2512FK-07280RL (YAGEO) is a direct functional equivalent meeting all electrical and mechanical specifications. This substitute maintains identical electrical performance across the full operating temperature range and carries equivalent compliance certifications. The part is available in higher inventory volume (8652 pieces), supplied in Tape & Reel packaging format. Dimensional variations (length 0.250" vs 0.248", width 0.122" vs 0.126", height 0.65mm vs 0.66mm) remain within standard PCB footprint tolerances for 2512 package classification and do not affect circuit performance or board assembly compatibility.

Selection between these parts should be based on supply chain requirements, packaging format preference (Tape & Reel vs standard packaging), and inventory availability rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07280RL replace RC6432F2800CS in existing designs?

A: Yes. Both parts are 280 Ohms ±1% 1W thick film resistors in the 2512 (6432 Metric) package with identical electrical specifications, temperature coefficients, and operating ranges. Dimensional tolerances are within standard PCB footprint specifications for this package class.

Q: Are there packaging differences between these parts?

A: The RC6432F2800CS is supplied in standard packaging. The RC2512FK-07280RL is supplied in Tape & Reel (TR) format. Both formats are compatible with standard pick-and-place assembly equipment. Selection depends on manufacturing process requirements and inventory management preferences.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC6432F2800CS and RC2512FK-07280RL are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

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

A: The temperature coefficient specifies resistance change per degree Celsius across the operating range. Both parts maintain ±100ppm/°C, ensuring stable performance from -55°C to 155°C. This specification is critical for precision analog circuits and temperature-sensitive applications.

Q: Are dimensional differences between these parts significant?

A: Dimensional variations (RC6432F2800CS: 6.30mm x 3.20mm vs RC2512FK-07280RL: 6.35mm x 3.10mm) fall within standard 2512 package tolerances. Both parts mount to identical PCB footprints without modification. Height differences (0.66mm vs 0.65mm) are negligible for standard assembly processes.

Q: What does MSL 1 (Unlimited) rating mean?

A: MSL 1 indicates the component has unlimited shelf life without moisture sensitivity constraints. No baking or special storage conditions are required before assembly, simplifying inventory management and reducing component preparation time.
