Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF6040U are qualified based on the following criteria:

• Identical resistance value: 604 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 1W
• Compatible package: 2512 (6432 Metric)
• Matching composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Equivalent RoHS compliance: ROHS3 Compliant
• Matching moisture sensitivity: MSL 1 (Unlimited)

The CRCW2512604RFKEG from Vishay Dale meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF6040U and CRCW2512604RFKEG are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Procurement cost and volume pricing
• Existing design qualification history with either manufacturer
• Inventory management and stock rotation policies

The CRCW2512604RFKEG currently has higher inventory availability (7057 pieces) compared to the ERJ-S1TF6040U (832 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512604RFKEG be used as a direct replacement for ERJ-S1TF6040U in automotive applications?

A: Yes. Both parts share identical electrical specifications (604 Ohms ±1%, 1W), matching package dimensions (2512), and equivalent automotive qualification (AEC-Q200). Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

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

A: Minor dimensional variations exist. The ERJ-S1TF6040U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while the CRCW2512604RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both share identical height (0.028" / 0.70mm maximum) and are compatible with standard 2512 PCB footprints.

Q: Do both parts meet the same compliance and certification standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Both have MSL 1 (Unlimited) moisture sensitivity rating and identical ECCN and HTSUS classifications.

Q: What is the temperature coefficient difference between these parts?

A: Both parts have identical temperature coefficients of ±100ppm/°C and operate across the same temperature range (-55°C ~ 155°C).
