Substitute Part Grouping Explanation

Substitute parts for the RC6432F3013CS are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Mandatory Matching Parameters:

• Resistance value: 301 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Two substitute parts meet all mandatory parameters: CRCW2512301KFKEG (Vishay Dale) and RMCF2512FT301K (Stackpole Electronics Inc). Both maintain identical electrical performance and mechanical compatibility with the original RC6432F3013CS specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts CRCW2512301KFKEG and RMCF2512FT301K are qualified equivalents to the RC6432F3013CS based on matching electrical specifications and mechanical dimensions. All three parts maintain Active product status and ROHS3 compliance.

The CRCW2512301KFKEG (Vishay Dale) and RMCF2512FT301K (Stackpole Electronics Inc) both carry AEC-Q200 automotive qualification ratings, which exceeds the base specification of the RC6432F3013CS. This additional qualification does not restrict their use in non-automotive applications and provides enhanced reliability documentation.

Dimensional variations exist in width and seated height across the three parts. The RC6432F3013CS and RMCF2512FT301K share identical length and width dimensions (6.30mm x 3.20mm), while the CRCW2512301KFKEG has a width of 3.15mm. All three parts fit within the 2512 package specification and are mechanically compatible for standard PCB layouts designed for this package class.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512301KFKEG replace RC6432F3013CS in existing designs?

A: Yes. The CRCW2512301KFKEG meets all mandatory electrical parameters (301 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and is packaged in the 2512 (6432 Metric) format. The width dimension differs by 0.05mm (3.15mm vs 3.20mm), which remains within standard PCB pad tolerances for this package class.

Q: What is the difference between the three parts?

A: All three parts share identical electrical specifications. The primary differences are manufacturer (Samsung, Vishay Dale, Stackpole), packaging format (bulk vs Tape & Reel), and additional certifications. The CRCW2512301KFKEG and RMCF2512FT301K include AEC-Q200 automotive qualification. Seated height varies slightly: RC6432F3013CS at 0.66mm maximum versus 0.70mm maximum for the substitute parts.

Q: Are the substitute parts suitable for moisture-sensitive applications?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Does the AEC-Q200 rating on substitute parts affect their use in non-automotive applications?

A: No. AEC-Q200 qualification represents an additional quality and reliability standard. Parts qualified to this standard are fully compatible with non-automotive applications and do not impose restrictions on their use.

Q: What is the impact of the 0.04mm height difference between parts?

A: The maximum seated height difference (0.66mm vs 0.70mm) is negligible for standard PCB assembly processes. Both dimensions fall within acceptable tolerances for 2512 package class components and do not affect electrical performance or mechanical fit in standard designs.
