Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF8250U are qualified based on the following criteria:

• Identical resistance value: 825 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 CRCW2512825RFKEG from Vishay Dale meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF8250U and CRCW2512825RFKEG are active production components with identical electrical specifications and automotive qualification. Selection between these parts should be based on:

• Procurement availability and lead time requirements
• Supplier inventory levels (Panasonic: 992 units; Vishay Dale: 4477 units)
• Cost and volume pricing structures from respective suppliers
• Existing supply chain relationships and qualification documentation
• Physical dimensions tolerance (Panasonic: 0.252" L x 0.126" W; Vishay Dale: 0.248" L x 0.124" W) for space-constrained applications

Both components maintain ROHS3 compliance, AEC-Q200 automotive qualification, and identical electrical performance across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512825RFKEG be used as a direct replacement for ERJ-S1TF8250U in automotive applications?

A: Yes. Both components meet AEC-Q200 automotive qualification, share identical electrical specifications (825 Ohms ±1%, 1W, ±100ppm/°C), and are packaged in the 2512 (6432 Metric) form factor. Both are ROHS3 compliant with MSL 1 rating.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The ERJ-S1TF8250U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while the CRCW2512825RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both have identical height (0.028" / 0.70mm maximum). These differences fall within standard 2512 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of the anti-sulfur feature on the ERJ-S1TF8250U?

A: The anti-sulfur protection is a specific feature of the Panasonic ERJ-S1T series. The Vishay Dale CRCW2512825RFKEG does not list this feature in its specification. For applications requiring explicit anti-sulfur protection, the ERJ-S1TF8250U should be specified.

Q: Are both parts suitable for high-temperature automotive environments?

A: Yes. Both components operate across the -55°C ~ 155°C temperature range with ±100ppm/°C temperature coefficient, meeting automotive thermal requirements.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying logistics and inventory management.
