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

Mechanical Specifications:

  • Package format: 2512 (6432 Metric) (exact match required)
  • Number of terminations: 2 (exact match required)

Compliance & Environmental:

  • RoHS3 Compliant status (required)
  • Moisture Sensitivity Level 1 (required)
  • Composition: Thick Film (exact match required)

The CRCW2512187KFKEG manufactured by Vishay Dale meets all substitution criteria and is classified as an equivalent part.

Engineering Selection Recommendations

Both the RC6432F1873CS and CRCW2512187KFKEG are Active product status components with full ROHS3 compliance and identical electrical specifications. The CRCW2512187KFKEG carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Selection between these parts should be based on application requirements, supply chain availability, and packaging format preference (tape & reel for CRCW2512187KFKEG versus standard packaging for RC6432F1873CS). Both components are suitable for direct substitution in circuits designed for 187 kOhms ±1% 1W thick film resistors in the 2512 package format.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512187KFKEG replace the RC6432F1873CS in all applications?

A: Yes. Both components share identical electrical specifications (187 kOhms ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C), identical package format (2512 / 6432 Metric), and equivalent compliance certifications (ROHS3, MSL 1). Physical dimensions are within acceptable tolerances for PCB assembly.

Q: What is the significance of AEC-Q200 qualification on the CRCW2512187KFKEG?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW2512187KFKEG meets this standard, making it suitable for automotive applications requiring enhanced reliability documentation. The RC6432F1873CS does not carry this designation.

Q: Are there packaging differences between these parts?

A: The CRCW2512187KFKEG is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. The RC6432F1873CS uses standard packaging. Both are compatible with 2512 package footprints.

Q: Do the slight dimensional variations affect PCB compatibility?

A: No. The dimensional differences (width 3.20mm vs 3.15mm, height 0.66mm vs 0.70mm) are within standard PCB design tolerances for 2512 package components and do not affect footprint compatibility or assembly.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Both carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.
