• Moisture sensitivity level: 1 (Unlimited)

The CRCW25122K80FKEG from Vishay Dale meets all electrical and mechanical specifications required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, thermal characteristics, and environmental compliance ratings. Dimensional variations (height-seated maximum: 0.66mm vs. 0.70mm) remain within acceptable mechanical tolerances for standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F2801CS and CRCW25122K80FKEG maintain Active product status, ensuring continued availability and manufacturing support. Selection between these parts is based on supply chain requirements and application-specific certifications.

The RC6432F2801CS features moisture-resistant construction as a primary design characteristic. The CRCW25122K80FKEG carries AEC-Q200 automotive qualification, indicating suitability for automotive and high-reliability applications requiring formal qualification documentation.

Both components satisfy ROHS3 compliance and REACH unaffected status, meeting environmental regulatory requirements for industrial and commercial applications. The identical electrical specifications (2.8 kOhms ±1%, 1W, ±100ppm/°C) and operating temperature range (-55°C ~ 155°C) ensure functional equivalence in circuit design.

Dimensional compatibility is confirmed across all critical parameters. The maximum height variation of 0.04mm (0.70mm vs. 0.66mm) remains within standard PCB assembly tolerances and does not impact reflow soldering or component placement processes.

Frequently Asked Questions (FAQ)

Q: Can CRCW25122K80FKEG directly replace RC6432F2801CS in existing designs?

A: Yes. Both parts share identical electrical specifications (2.8 kOhms ±1%, 1W, ±100ppm/°C), operating temperature range (-55°C ~ 155°C), package format (2512), and environmental compliance ratings (ROHS3, MSL 1). Mechanical dimensions are compatible within standard assembly tolerances.

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

A: AEC-Q200 is an automotive qualification standard. The CRCW25122K80FKEG meets formal automotive reliability requirements. The RC6432F2801CS does not carry this designation but remains suitable for non-automotive applications.

Q: Are there dimensional concerns when substituting between these parts?

A: Dimensional differences are minimal. Length remains 6.30mm for both parts. Width varies by 0.05mm (3.20mm vs. 3.15mm). Height-seated maximum differs by 0.04mm (0.66mm vs. 0.70mm). These variations fall within standard PCB design and assembly tolerances and do not affect functionality or placement.

Q: Do both parts require identical moisture handling procedures?

A: Yes. Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected. Both carry ECCN classification EAR99 and HTSUS code 8533.21.0030.

Q: Is the ±100ppm/°C temperature coefficient identical between both parts?

A: Yes. Both the RC6432F2801CS and CRCW25122K80FKEG specify ±100ppm/°C temperature coefficient, ensuring equivalent thermal stability across the -55°C ~ 155°C operating range.
