Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F19R6CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 19.6 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level 1 (Unlimited) (minimum requirement)

The CRCW251219R6FKEG manufactured by Vishay Dale meets all electrical, mechanical, and compliance criteria for direct substitution. The primary distinction is the addition of AEC-Q200 automotive qualification and Tape & Reel packaging, which do not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F19R6CS (Samsung Electro-Mechanics):

• Select when moisture-resistant thick film composition is the primary design requirement
• Suitable for general industrial and consumer applications
• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected

CRCW251219R6FKEG (Vishay Dale):

• Select when AEC-Q200 automotive qualification is required or beneficial for supply chain continuity
• Tape & Reel packaging format supports automated assembly processes
• Active product status with higher inventory availability (2,650 pieces)
• ROHS3 compliant and REACH unaffected
• Dimensional compatibility confirmed within PCB layout tolerances

Both parts are functionally and mechanically interchangeable. Selection between them should be based on packaging requirements, supply chain preferences, and whether automotive qualification adds value to the application.

Frequently Asked Questions (FAQ)

Q: Can CRCW251219R6FKEG replace RC6432F19R6CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance value (19.6 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package type (2512 / 6432 Metric). Dimensional variations (width 0.126" vs 0.124", height 0.026" vs 0.028") are within standard PCB layout tolerances.

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

A: AEC-Q200 is an automotive industry qualification standard. The CRCW251219R6FKEG carries this certification, which indicates compliance with automotive reliability and testing requirements. This qualification does not restrict use in non-automotive applications and may provide additional confidence in component reliability.

Q: Are there packaging differences between these parts?

A: Yes. The RC6432F19R6CS uses standard packaging, while the CRCW251219R6FKEG is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly. Both formats contain identical components; the difference is in delivery and handling method.

Q: Do both parts meet RoHS and REACH compliance?

A: Yes. Both RC6432F19R6CS and CRCW251219R6FKEG are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating moisture-related supply chain constraints.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, with consideration for packaging format. The Tape & Reel format of CRCW251219R6FKEG is directly compatible with standard automated pick-and-place equipment. The RC6432F19R6CS in standard packaging may require manual feeding or tray-based automation depending on assembly line configuration.
