Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F3483U are identified based on strict equivalence across the following critical parameters:

Resistance value and tolerance (348 kOhms ±1%), power rating (0.5W), package type (1210 / 3225 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive AEC-Q200 certification. All substitute parts must maintain ROHS3 compliance and MSL 1 rating. Physical dimensions and termination count must remain consistent. Substitutes are valid only when all specified parameters match the original component.

Parameter Comparison

Engineering Selection Recommendations

The CRCW1210348KFKEA (Vishay Dale) is a direct electrical and mechanical equivalent to the ERJ-S14F3483U. Both components meet identical electrical specifications, automotive AEC-Q200 certification, and regulatory compliance requirements (ROHS3, REACH Unaffected). The substitute part maintains the same 1210 package footprint, resistance value, tolerance, power rating, and temperature operating range. Both components are active products with established supply availability. Selection between these parts may be based on procurement lead time, inventory availability, or established supplier relationships, as all technical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210348KFKEA replace ERJ-S14F3483U in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and meet identical electrical and mechanical specifications required for automotive circuit design.

Q: Are there dimensional differences between these parts?

A: Both parts use the 1210 (3225 Metric) package with identical length and width (0.126" L x 0.098" W). The seated height differs slightly (0.028" vs 0.024" maximum), which does not affect PCB layout or assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ERJ-S14F3483U and CRCW1210348KFKEA are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What determines substitutability for this resistor?

A: Substitutability is determined by matching resistance value (348 kOhms), tolerance (±1%), power rating (0.5W), package type (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive certification (AEC-Q200).

Q: Are there any anti-sulfur coating differences?

A: The ERJ-S14F3483U specifies anti-sulfur coating as a feature. The CRCW1210348KFKEA specification provided does not explicitly list anti-sulfur coating. Verify coating requirements with the supplier if sulfur resistance is critical for your application environment.
