Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1741U is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.74 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package: 1210 (3225 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 ERJ-14NF1741U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. Differences in product status and manufacturing series do not affect functional equivalence when specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1741U is the preferred selection for new designs due to its active production status. The ERJ-14NF1741U provides functional equivalence for applications where the primary part is unavailable, with the understanding that it carries a "Not For New Designs" designation. Both parts meet identical electrical specifications, package requirements, and automotive compliance standards. Selection between these parts should be based on availability and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1741U be used as a direct replacement for ERJ-S14F1741U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across the identical temperature range (-55°C ~ 155°C), and share all critical electrical parameters including resistance value, tolerance, power rating, and temperature coefficient.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF1741U?

A: This designation indicates the part is in mature production but not recommended for incorporation into new product designs. It remains suitable for replacement, repair, and legacy system applications where the part was originally specified.

Q: Are there dimensional differences between these parts?

A: No. Both parts use the 1210 (3225 Metric) package with identical physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
