Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF3920U are qualified based on the following criteria:

Resistance value must be 392 Ohms with ±1% tolerance. Power rating must be 1W. Package must be 2512 (6432 Metric) with identical termination count (2 terminations). Composition must be thick film. Temperature coefficient must be ±100ppm/°C. Operating temperature range must be -55°C ~ 155°C. Automotive AEC-Q200 qualification is required. RoHS3 compliance and MSL 1 rating must be maintained. Packaging format must be Tape & Reel (TR).

All identified substitutes meet these electrical and mechanical parameters without exception.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S1TF3920U, CRCW2512392RFKEG, and RMCF2512FT392R—are functionally equivalent for applications requiring a 392 Ohms 1W 2512 package resistor with ±1% tolerance and automotive AEC-Q200 qualification. Selection between these parts may be based on availability and supply chain considerations. The ERJ-S1TF3920U includes anti-sulfur coating as an additional feature. All parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and identical electrical performance across the specified operating temperature range of -55°C to 155°C. Physical dimensions vary slightly between manufacturers within acceptable tolerances for standard PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512392RFKEG replace ERJ-S1TF3920U in automotive applications? A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (392 Ohms ±1%, 1W, ±100ppm/°C), and use the 2512 package with equivalent footprint compatibility.

Q: What is the difference between ERJ-S1TF3920U and RMCF2512FT392R? A: Both parts are electrically and mechanically identical in all specified parameters. The primary difference is manufacturer (Panasonic vs. Stackpole). ERJ-S1TF3920U includes anti-sulfur coating; RMCF2512FT392R does not list this feature.

Q: Are physical dimensions identical across all three parts? A: Physical dimensions are within acceptable tolerance ranges for standard 2512 package footprints. ERJ-S1TF3920U measures 0.252" L x 0.126" W (6.40mm x 3.20mm). CRCW2512392RFKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). RMCF2512FT392R measures 0.248" L x 0.126" W (6.30mm x 3.20mm). All three have maximum seated height of 0.028" (0.70mm) and are compatible with standard 2512 PCB layouts.

Q: Do all substitute parts carry the same compliance certifications? A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and hold AEC-Q200 automotive qualification. REACH status is Unaffected for all parts.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. All three parts operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient, making them suitable for the same thermal environments.
