Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2553U is determined by strict alignment of the following parameters:

• Resistance value: 255 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 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 CRCW2512255KFKEG from Vishay Dale meets all these criteria and qualifies as a direct substitute. Both components share identical electrical specifications, thermal characteristics, and automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF2553U and CRCW2512255KFKEG are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on availability, supply chain considerations, or existing design qualification history.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512255KFKEG replace ERJ-S1TF2553U in automotive applications? A: Yes. Both components meet AEC-Q200 automotive qualification, share identical electrical specifications (255 kOhms ±1% 1W), and are packaged in the 2512 (6432 Metric) form factor with equivalent physical dimensions.

Q: Are there dimensional differences between these parts? A: The ERJ-S1TF2553U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while the CRCW2512255KFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both have identical maximum seated height of 0.028" (0.70mm). These minor dimensional variations remain within the 2512 package specification tolerance and do not affect PCB layout compatibility.

Q: Do both parts require the same moisture handling procedures? A: Yes. Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.

Q: Are there differences in temperature performance? A: No. Both components operate across -55°C ~ 155°C with identical temperature coefficient of ±100ppm/°C.
