Substitute Part Grouping Explanation

Substitute parts for the RC6432F273CS are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 27 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Moisture resistance: Required
• Number of terminations: 2

Compliance Requirements:

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

The RC2512FK-0727KL from YAGEO meets all specified electrical, mechanical, and compliance criteria, establishing it as a direct functional equivalent within the 2512 package class.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F273CS and RC2512FK-0727KL are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application requirements and supply chain considerations:

RC6432F273CS (Samsung Electro-Mechanics) is appropriate when bulk packaging is required or when Samsung-sourced components are specified in design documentation.

RC2512FK-0727KL (YAGEO) is appropriate when tape and reel packaging is required for automated assembly processes or when YAGEO supply chain integration is preferred. This part maintains identical electrical performance and environmental ratings.

Both components satisfy the same circuit design requirements and environmental operating conditions. Dimensional variations between parts (length 6.30mm vs 6.35mm, width 3.20mm vs 3.10mm) remain within standard PCB footprint tolerances for the 2512 package class and do not affect board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-0727KL replace RC6432F273CS in existing designs?

A: Yes. Both parts maintain identical electrical specifications (27 kOhms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), and use the same 2512 package format. Dimensional differences (length and width variations within 0.05mm) fall within standard PCB footprint tolerances.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging format. RC6432F273CS is supplied in bulk packaging, while RC2512FK-0727KL is supplied in tape and reel format. Electrical and mechanical specifications are equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC6432F273CS and RC2512FK-0727KL carry ROHS3 compliance certification and REACH unaffected status.

Q: Does the MSL 1 rating apply to both parts?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity level rating, indicating no moisture precautions are required during storage or handling.

Q: Which part should be selected for automated assembly?

A: RC2512FK-0727KL is designed for automated assembly with tape and reel packaging. RC6432F273CS in bulk packaging is suitable for manual assembly or pick-and-place operations with bulk feeders.

Q: Are the physical dimensions identical?

A: Dimensions are within standard tolerance for the 2512 package class. RC6432F273CS measures 6.30mm x 3.20mm; RC2512FK-0727KL measures 6.35mm x 3.10mm. Both mount identically on standard 2512 PCB footprints.
