Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF4422U is determined by the following critical parameters:

• Resistance value: 44.2 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

The CRCW251244K2FKEG from Vishay Dale meets all these electrical and mechanical specifications, making it a direct substitute for the Panasonic ERJ-S1TF4422U in applications requiring equivalent performance and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF4422U and CRCW251244K2FKEG are active production components with identical electrical specifications and automotive AEC-Q200 certification. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating equivalent reliability for automotive and industrial applications.

The CRCW251244K2FKEG from Vishay Dale is a direct functional equivalent. Physical dimensions show minor variations within the 2512 package tolerance range (6.30mm x 3.15mm versus 6.40mm x 3.20mm), with both maintaining the same 0.70mm maximum seated height. These dimensional differences do not affect PCB layout compatibility or electrical performance.

Selection between these parts should be based on availability, supply chain requirements, and procurement preferences, as both meet identical performance and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251244K2FKEG replace the ERJ-S1TF4422U in automotive applications?
