Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4023U is determined by strict equivalence across the following critical parameters:

• Resistance value: 402 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package type: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Physical dimensions and termination count

The ERJ-14NF4023U qualifies as a direct substitute based on matching all electrical specifications and package requirements. Differences in product status and compliance certifications are noted but do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F4023U is the preferred selection for new designs due to its active product status and ROHS3 compliance certification. This part maintains full automotive AEC-Q200 qualification with anti-sulfur coating, meeting current regulatory requirements for automotive and industrial applications.

The ERJ-14NF4023U provides electrical and mechanical equivalence but carries a "Not For New Designs" status and RoHS non-compliance designation. This substitute is suitable only for legacy system maintenance, repair operations, or applications where RoHS compliance is not a requirement. Selection of this substitute requires explicit design justification based on supply availability or application-specific constraints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4023U be used as a direct replacement for ERJ-S14F4023U in new automotive designs?

A: No. While the ERJ-14NF4023U matches all electrical and mechanical specifications, its "Not For New Designs" status and RoHS non-compliance make it unsuitable for new automotive applications. The ERJ-S14F4023U is the required selection for new designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical 1210 (3225 Metric) package dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) with maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable at the PCB level.

Q: Do both parts meet automotive qualification requirements?

A: Both parts carry AEC-Q200 automotive qualification. However, only the ERJ-S14F4023U maintains current compliance status with ROHS3 certification, making it the appropriate choice for modern automotive applications.

Q: What is the significance of the anti-sulfur coating on the ERJ-S14F4023U?

A: The anti-sulfur feature on the ERJ-S14F4023U provides enhanced reliability in environments with sulfur-containing contaminants. The ERJ-14NF4023U does not specify this feature, representing a functional difference beyond basic electrical equivalence.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate across the -55°C ~ 155°C temperature range with ±100ppm/°C temperature coefficient, meeting standard automotive thermal requirements. Selection should be based on specific application temperature profiles and compliance requirements.
