Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1403U is determined by strict alignment of the following parameters:

• Resistance value: 140 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive certification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The CRCW2512140KFKEG manufactured by Vishay Dale meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications, thermal characteristics, and automotive qualification status. Physical dimensions show minor variations within acceptable tolerances for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF1403U and CRCW2512140KFKEG are active production parts with identical electrical and thermal specifications. Selection between these components should be based on availability, lead time, and supply chain requirements. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, confirming suitability for regulated applications. The minor dimensional variations (0.252" vs 0.248" length, 0.126" vs 0.124" width) fall within standard PCB assembly tolerances and do not affect functional compatibility or board layout.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512140KFKEG replace ERJ-S1TF1403U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (140 kOhms ±1%, 1W), and operate across the same temperature range (-55°C ~ 155°C). They are functionally interchangeable.

Q: Are there physical compatibility concerns between these two parts?

A: No. Both use the 2512 (6432 Metric) package with identical maximum seated height (0.028" / 0.70mm). Length and width dimensions vary by less than 0.004", which is within standard PCB assembly tolerances.

Q: Do both parts meet RoHS and REACH compliance requirements?

A: Yes. Both ERJ-S1TF1403U and CRCW2512140KFKEG are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity rating for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there differences in temperature coefficient performance?

A: No. Both parts specify ±100ppm/°C temperature coefficient, ensuring identical thermal stability across the operating range.
