ERJ-S14F1070U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1070U is a 107 Ohms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 1029 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require alternative qualified sources. The ERJ-14NF1070U represents a direct functional equivalent from the same manufacturer with identical electrical and mechanical specifications, though it carries a "Not For New Designs" status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1070U is determined by strict equivalence across the following parameters:

• Resistance value: 107 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-14NF1070U meets all these criteria and qualifies as a direct substitute. The primary distinction is product lifecycle status: ERJ-S14F1070U is active for new designs, while ERJ-14NF1070U is designated "Not For New Designs" but remains functionally equivalent for existing applications.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S14F1070U is the specified choice due to its active product status and ongoing manufacturer support. This part carries full automotive AEC-Q200 qualification and ROHS3 compliance, meeting current regulatory requirements.

The ERJ-14NF1070U serves as a functional equivalent for existing applications or legacy system maintenance where the part is already qualified in the design. Its "Not For New Designs" designation reflects manufacturer lifecycle management rather than technical deficiency. All electrical, mechanical, and environmental specifications remain identical to the primary part.

Both parts are manufactured by Panasonic Electronic Components and share identical package footprints, thermal characteristics, and reliability ratings. Selection between these two parts depends solely on design phase and existing qualification status within the application.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1070U be used as a direct replacement for ERJ-S14F1070U in new designs?

A: Electrically and mechanically, yes. However, design best practices recommend using ERJ-S14F1070U for new implementations due to its active product status. ERJ-14NF1070U is suitable for sustaining production of existing designs where it is already qualified.

Q: Are there any differences in anti-sulfur coating between these parts?

A: ERJ-S14F1070U explicitly includes anti-sulfur coating in its specification. ERJ-14NF1070U does not list this feature. This distinction may be relevant for applications in high-sulfur environments.

Q: Do both parts have identical PCB footprints?

A: Yes. Both parts use the 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). No PCB layout modifications are required for substitution.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the manufacturer is transitioning the part out of active production. Existing designs may continue using this part, but new projects should specify the active equivalent (ERJ-S14F1070U) to ensure long-term supply availability.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both ERJ-S14F1070U and ERJ-14NF1070U carry AEC-Q200 automotive qualification, meeting automotive reliability and quality standards.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special desiccant requirements.
