Substitute Part Grouping Explanation

Substitute parts for the RC5025F2743CS are qualified based on the following criteria:

Electrical Compatibility:

• Resistance value: 274 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility:

• Package type: 2010 (5025 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) (exact match required)

Regulatory Compliance:

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

Substitute parts may have higher power ratings (0.75W vs. 0.667W) and additional features (automotive AEC-Q200 certification) without affecting substitution validity, as these represent enhanced or equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010274KFKEF (Vishay Dale) is the primary substitute for the RC5025F2743CS. This part maintains all critical electrical parameters (274 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C) and mechanical compatibility (2010 package, identical dimensions). The CRCW2010274KFKEF offers a higher power rating (0.75W vs. 0.667W) and includes automotive AEC-Q200 certification. Product status is Active, ensuring long-term availability and supply chain stability. RoHS3 and REACH compliance are maintained.

ERJ-12SF2743U (Panasonic Electronic Components) is a secondary substitute meeting all electrical and mechanical requirements. This part also provides 0.75W power rating and AEC-Q200 automotive qualification. However, product status is classified as "Not For New Designs," indicating this part is in mature phase with potential future discontinuation. This part is suitable for replacement or repair applications but not recommended for new product development.

Selection between CRCW2010274KFKEF and ERJ-12SF2743U should prioritize CRCW2010274KFKEF for new designs due to Active product status and long-term availability assurance.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010274KFKEF directly replace RC5025F2743CS in existing designs?

A: Yes. Both parts share identical electrical specifications (274 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm dimensions, 2 terminations). The CRCW2010274KFKEF's higher power rating (0.75W vs. 0.667W) provides equivalent or superior performance in the same footprint.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: The power rating indicates maximum continuous power dissipation. The CRCW2010274KFKEF and ERJ-12SF2743U are rated for 0.75W, compared to the RC5025F2743CS at 0.667W. In applications where the RC5025F2743CS operates within its 0.667W limit, substitutes with 0.75W rating provide additional thermal margin without affecting circuit performance.

Q: Why is ERJ-12SF2743U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase. While currently available (14,800 pcs in stock), Panasonic has signaled this part may be discontinued in the future. For new product development, CRCW2010274KFKEF is recommended to ensure long-term component availability.

Q: Are there packaging differences between these parts?

A: All three parts use 2010 (5025 Metric) package with identical length and width (5.00mm x 2.50mm). Maximum seated height varies slightly: RC5025F2743CS at 0.026" (0.66mm), while CRCW2010274KFKEF and ERJ-12SF2743U are 0.028" (0.70mm). This 0.002" difference is negligible for standard PCB assembly and does not affect substitution compatibility.

Q: Do all substitute parts maintain RoHS3 and REACH compliance?

A: Yes. RC5025F2743CS, CRCW2010274KFKEF, and ERJ-12SF2743U are all ROHS3 Compliant and REACH Unaffected, with Moisture Sensitivity Level 1 (Unlimited). Regulatory compliance is maintained across all qualified substitutes.

Q: What is the significance of AEC-Q200 certification on substitute parts?

A: AEC-Q200 is an automotive qualification standard. CRCW2010274KFKEF and ERJ-12SF2743U include this certification, indicating enhanced reliability testing and suitability for automotive applications. The RC5025F2743CS does not carry this designation but remains suitable for general industrial use. AEC-Q200 certification does not restrict use in non-automotive applications.
