Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1333U is determined by the following critical parameters:

• Resistance value: 133 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 qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The CRCW2512133KFKEG manufactured by Vishay Dale meets all specified electrical and mechanical parameters. Both components share identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both are qualified to AEC-Q200 automotive standards and comply with ROHS3 requirements. Physical dimensions are within acceptable tolerance for the 2512 package format.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF1333U and CRCW2512133KFKEG are active products with full automotive AEC-Q200 qualification and ROHS3 compliance. Selection between these components is based on availability, supply chain considerations, and procurement requirements. The dimensional variance between the two parts (0.252" vs 0.248" length, 0.126" vs 0.124" width) remains within the 2512 package specification tolerance and does not affect functional performance or PCB layout compatibility. Both components maintain identical electrical performance across the specified operating temperature range and are suitable for direct substitution in automotive applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512133KFKEG replace ERJ-S1TF1333U in automotive applications?

A: Yes. Both components meet AEC-Q200 automotive qualification, share identical electrical specifications (133 kOhms ±1%, 1W, ±100ppm/°C), and are packaged in the 2512 (6432 Metric) format. Physical dimensions are within acceptable tolerance for the package specification.

Q: Are there differences in physical dimensions between these parts?

A: The ERJ-S1TF1333U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while the CRCW2512133KFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both share the same maximum seated height of 0.028" (0.70mm). These dimensional variations are within 2512 package tolerance and do not impact PCB layout or assembly compatibility.
