Substitute Part Grouping Explanation

Substitute parts for the RC6432F13R3CS are qualified based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 13.3 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The CRCW251213R3FKEG manufactured by Vishay Dale satisfies all substitution criteria. This part maintains identical electrical specifications, mechanical dimensions within tolerance, and equivalent compliance certifications. The addition of AEC-Q200 automotive qualification in the Vishay part represents an enhanced feature set that does not restrict its use in non-automotive applications.

Engineering Selection Recommendations

Primary Selection (RC6432F13R3CS): The Samsung Electro-Mechanics RC6432F13R3CS remains the primary choice when original part specifications are required. This component is Active in product status with established supply availability (776 units in stock). It carries ROHS3 compliance and REACH Unaffected status, meeting standard environmental regulations.

Substitute Selection (CRCW251213R3FKEG): The Vishay Dale CRCW251213R3FKEG qualifies as a direct electrical and mechanical substitute. All critical parameters—resistance, tolerance, power rating, package dimensions, and operating temperature range—are identical. Both components maintain ROHS3 compliance and MSL 1 rating. The Vishay part includes AEC-Q200 automotive qualification, which provides additional reliability assurance without restricting application scope. Supply availability for the Vishay part is higher (4079 units in stock).

Compliance Verification: Both parts satisfy ROHS3 requirements and carry REACH Unaffected status. Neither component introduces compliance restrictions for standard industrial or commercial applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW251213R3FKEG replace RC6432F13R3CS in existing designs?

A: Yes. The CRCW251213R3FKEG meets all electrical and mechanical specifications required for direct substitution. Resistance value, tolerance, power rating, package type, and operating temperature range are identical. Physical dimensions are compatible within standard PCB assembly tolerances.

Q: What is the significance of AEC-Q200 qualification on the Vishay part?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors and passive components. This qualification indicates the Vishay part has undergone enhanced reliability testing. For non-automotive applications, this certification does not impose restrictions and represents an additional quality assurance measure.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within acceptable tolerances. The Samsung part measures 0.248" L x 0.126" W with 0.026" maximum seated height. The Vishay part measures 0.248" L x 0.124" W with 0.028" maximum seated height. These differences fall within standard PCB assembly specifications and do not affect functional compatibility.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both the RC6432F13R3CS and CRCW251213R3FKEG carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain requirements and inventory availability. Both parts are Active in product status and fully qualified for equivalent performance. The Vishay CRCW251213R3FKEG offers higher current stock levels (4079 units versus 776 units).

Q: Are packaging options different between these parts?

A: The Samsung part is supplied in standard packaging. The Vishay part is available in Cut Tape (CT) and Digi-Reel® formats, with Tape & Reel (TR) as the standard supplier package. Packaging format selection depends on assembly process requirements and volume specifications.
