Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F2050CS are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Electrical Parameters:

• Resistance value: 205 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Physical dimensions within specified tolerances

Compliance Parameters:

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

The identified substitute parts CRCW2512205RFKEG and CRCW2512205RFKEGHP satisfy these core parameters. The CRCW2512205RFKEGHP variant provides enhanced power rating (1.5W versus 1W) and pulse withstanding capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

CRCW2512205RFKEG Selection: This substitute maintains direct electrical and mechanical equivalence to the RC6432F2050CS. Both parts share identical resistance, tolerance, temperature coefficient, and operating temperature specifications. The CRCW2512205RFKEG incorporates Automotive AEC-Q200 qualification, providing enhanced reliability documentation for applications requiring automotive-grade components. Physical dimensions are within acceptable tolerances for PCB layout compatibility. RoHS3 compliance and MSL 1 rating match the original specification.

CRCW2512205RFKEGHP Selection: This variant provides the same electrical parameters as the RC6432F2050CS with an increased power rating of 1.5W and pulse withstanding capability. The CRCW2512205RFKEGHP is suitable for applications where the original 1W rating requires margin or where transient pulse conditions exist. Automotive AEC-Q200 qualification and all compliance certifications remain equivalent. Physical dimensions and thermal characteristics remain compatible with the original design envelope.

Both substitute parts are Active status components with current inventory availability. Selection between CRCW2512205RFKEG and CRCW2512205RFKEGHP depends on application power dissipation requirements and pulse withstanding needs.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512205RFKEG be used as a direct replacement for RC6432F2050CS?

A: Yes. Both parts share identical resistance (205 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package format (2512). Physical dimensions are within acceptable tolerances for PCB compatibility. All compliance certifications (RoHS3, MSL 1) are equivalent.

Q: What is the difference between CRCW2512205RFKEG and CRCW2512205RFKEGHP?

A: The primary difference is power rating. CRCW2512205RFKEG is rated at 1W, matching the RC6432F2050CS specification. CRCW2512205RFKEGHP is rated at 1.5W and includes pulse withstanding capability. All other electrical parameters remain identical. The CRCW2512205RFKEGHP is suitable for applications requiring higher power dissipation margin or pulse tolerance.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The RC6432F2050CS has a maximum seated height of 0.026" (0.66mm) and width of 0.126" (3.20mm). Both Vishay Dale substitutes have a maximum seated height of 0.028" (0.70mm) and width of 0.124" (3.15mm). These differences are within standard PCB design tolerances and do not affect mechanical compatibility in standard 2512 footprints.

Q: Do the substitute parts have automotive qualification?

A: Yes. Both CRCW2512205RFKEG and CRCW2512205RFKEGHP carry Automotive AEC-Q200 qualification. The RC6432F2050CS does not specify automotive qualification in the provided parameters.

Q: What is the Moisture Sensitivity Level for these parts?

A: All three parts (RC6432F2050CS, CRCW2512205RFKEG, and CRCW2512205RFKEGHP) have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute should I select for a new design?

A: Selection depends on application requirements. For direct 1W equivalence with automotive qualification, use CRCW2512205RFKEG. For applications requiring higher power margin or pulse withstanding capability, use CRCW2512205RFKEGHP. Both are Active status components with current inventory availability.
