Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F44R2CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 44.2 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the original component in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F44R2CS (Samsung Electro-Mechanics): Primary choice when Samsung sourcing is specified or preferred. Active production status with 1102 pieces in inventory.

Frequently Asked Questions (FAQ)

Q: Can CRCW251244R2FKEG be used as a direct replacement for RC6432F44R2CS?

A: Yes, with dimensional verification. The CRCW251244R2FKEG meets all electrical specifications (44.2 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C). The width dimension is 0.124" (3.15mm) versus 0.126" (3.20mm) on the original. Verify that your PCB footprint tolerances accommodate this 0.02mm difference before implementation.

Q: Can RMCF2512FT44R2 be used as a direct replacement for RC6432F44R2CS?

A: Yes. The RMCF2512FT44R2 matches all electrical and mechanical specifications exactly, including dimensions (0.248" L x 0.126" W). Both parts are 2512 package thick film resistors with identical resistance, tolerance, power rating, and temperature characteristics.

Q: What is the difference between the three substitute options?

A: All three parts are electrically equivalent 44.2 Ohm ±1% 1W 2512 chip resistors. Differences are: (1) Manufacturer and series designation, (2) Packaging format (Cut Tape/Digi-Reel versus Tape & Reel), (3) Automotive AEC-Q200 qualification on Vishay and Stackpole parts, (4) Minor dimensional variation on the Vishay part (width 0.124" vs. 0.126"), and (5) Inventory availability levels.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RC6432F44R2CS, CRCW251244R2FKEG, and RMCF2512FT44R2 are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. No baking or desiccant storage is required before soldering.

Q: Can I use these parts in automotive applications?

A: The RC6432F44R2CS does not carry automotive qualification. The CRCW251244R2FKEG and RMCF2512FT44R2 both carry AEC-Q200 automotive qualification and are suitable for automotive applications. Verify application requirements before selection.

Q: What is the temperature coefficient significance?

A: The ±100ppm/°C temperature coefficient indicates that the resistance value will change by approximately 0.01% per degree Celsius across the operating range. All three parts share this specification, ensuring consistent performance stability across the -55°C to 155°C operating range.
