Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF19R6U is determined by strict alignment of the following parameters:

• Resistance value: 19.6 Ohms
• 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
• Moisture sensitivity: MSL 1

The CRCW251219R6FKEG from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF19R6U and CRCW251219R6FKEG are active production components with identical electrical and mechanical specifications. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. The primary distinction is manufacturer: Panasonic Electronic Components for the ERJ-S1TF19R6U and Vishay Dale for the CRCW251219R6FKEG. Selection between these parts should be based on supply availability, lead time, and established supplier relationships. The CRCW251219R6FKEG currently has higher inventory availability at 2650 units compared to 1096 units for the ERJ-S1TF19R6U.

Frequently Asked Questions (FAQ)

Q: Can CRCW251219R6FKEG be used as a direct replacement for ERJ-S1TF19R6U?

A: Yes. Both components share identical resistance value (19.6 Ohms), tolerance (±1%), power rating (1W), package type (2512), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Mechanical dimensions are within acceptable tolerance for PCB footprint compatibility.
