Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1370U is determined by strict equivalence across the following critical parameters:

• Resistance value: 137 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• 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-14NF1370U qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. Differences in product status and series designation do not affect functional equivalence in applications where the main part specifications are required.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1370U is the preferred selection for new designs due to its active production status and anti-sulfur feature. Both parts maintain identical electrical performance, mechanical compatibility, and automotive qualification standards.

The ERJ-14NF1370U serves as a functional equivalent for applications where supply of the primary part is constrained. Although designated "Not For New Designs," this part meets all specified electrical, mechanical, and compliance requirements. Selection between these parts should be based on availability and supply chain requirements rather than technical performance differences.

Both parts satisfy ROHS3 compliance, AEC-Q200 automotive qualification, and MSL 1 moisture sensitivity requirements, ensuring suitability for automotive and industrial applications across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1370U be used as a direct replacement for ERJ-S14F1370U?

A: Yes. Both parts share identical electrical specifications (137 Ohms ±1%, 0.5W), mechanical dimensions (1210 package), composition (thick film), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and automotive qualifications (AEC-Q200). The parts are mechanically and electrically interchangeable.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF1370U?

A: This designation indicates the part is in mature production but not recommended for new product development. However, it remains fully functional and compliant with all specified parameters. Use is appropriate for replacement, repair, or applications where supply of the primary part is unavailable.

Q: Are there differences in anti-sulfur coating between the two parts?

A: The ERJ-S14F1370U explicitly includes anti-sulfur coating. The ERJ-14NF1370U specification does not list this feature. In applications requiring anti-sulfur protection, the ERJ-S14F1370U is the specified choice.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, qualifying them for automotive and high-reliability industrial applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 1210 (3225 Metric) package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). They are footprint-compatible on PCB layouts.
