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

Mechanical Parameters:

• Package format: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

The CRCW251247R5FKEG from Vishay Dale meets all electrical and mechanical equivalence criteria. This substitute maintains identical resistance, tolerance, power rating, and temperature characteristics while providing additional automotive-grade certification (AEC-Q200) and alternative packaging in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

RC6432F47R5CS (Samsung Electro-Mechanics): This component is the primary specification and maintains Active product status with moisture-resistant thick film construction. It is suitable for general industrial and consumer applications requiring standard compliance certifications.

CRCW251247R5FKEG (Vishay Dale): This substitute provides equivalent electrical and mechanical performance with the addition of AEC-Q200 automotive-grade qualification. The component is supplied in Tape & Reel packaging, which is advantageous for automated assembly processes. Selection of this substitute is appropriate when automotive-grade reliability standards are required or when Tape & Reel packaging is mandated by manufacturing processes. Dimensional variations (width 0.124" vs. 0.126" and height 0.028" vs. 0.026") remain within 2512 package specifications and do not affect PCB footprint compatibility.

Both components maintain identical electrical performance, temperature stability, and regulatory compliance status (ROHS3, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can the CRCW251247R5FKEG replace the RC6432F47R5CS in existing designs?

A: Yes. Both components share identical electrical specifications (47.5 Ohms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C operating range) and are packaged in the 2512 (6432 Metric) format. Minor dimensional variations (0.002" width difference, 0.002" height difference) are within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Q: What is the primary difference between these two parts?

A: The CRCW251247R5FKEG includes AEC-Q200 automotive-grade certification and is supplied in Tape & Reel packaging, whereas the RC6432F47R5CS is supplied in standard packaging. Electrically and mechanically, both components are equivalent.

Q: Are there any compliance or regulatory differences?

A: Both components are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. No compliance differences exist between the two parts.

Q: Which component should be selected for automotive applications?

A: The CRCW251247R5FKEG is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive applications. The RC6432F47R5CS does not carry automotive certification.

Q: Are the packaging formats interchangeable?

A: The RC6432F47R5CS is supplied in standard packaging, while the CRCW251247R5FKEG is supplied in Tape & Reel format. Both formats contain identical components; the difference is in the delivery and handling method. Tape & Reel packaging is optimized for automated pick-and-place assembly, while standard packaging is suitable for manual or semi-automated processes.

Q: What is the Moisture Sensitivity Level (MSL) for both components?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.
