ERJ-S14F6981U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F6981U is a 6.98 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 990 units available in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components with equivalent electrical and mechanical characteristics. The ERJ-14NF6981U represents a legacy alternative that maintains electrical compatibility despite its "Not For New Designs" status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F6981U is determined by strict equivalence across the following critical parameters:

• Resistance value: 6.98 kOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The ERJ-14NF6981U meets all electrical and mechanical substitution criteria. The primary distinction is product lifecycle status: ERJ-S14F6981U is active production, while ERJ-14NF6981U is designated "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

For new designs and active production, the ERJ-S14F6981U is the preferred selection due to its active product status and higher current inventory availability. This part provides long-term supply continuity and full manufacturer support.

The ERJ-14NF6981U is electrically and mechanically equivalent and remains suitable for legacy system maintenance, field replacements, or applications where existing stock must be utilized. However, its "Not For New Designs" designation indicates that Panasonic does not recommend this part for new development projects.

Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance, making them interchangeable from a regulatory and environmental standpoint.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF6981U be used as a direct replacement for ERJ-S14F6981U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF6981U carries a "Not For New Designs" status. For new development, ERJ-S14F6981U is the recommended choice to ensure long-term supply availability and manufacturer support.

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

A: The ERJ-S14F6981U explicitly includes anti-sulfur protection in its specification. The ERJ-14NF6981U does not list this feature. For applications requiring anti-sulfur protection, ERJ-S14F6981U is the appropriate selection.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts use the 1210 (3225 Metric) package format with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: What is the difference in tolerance and temperature coefficient between these parts?

A: There is no difference. Both parts maintain ±1% tolerance and ±100ppm/°C temperature coefficient across the -55°C ~ 155°C operating range.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and are suitable for automotive circuit applications.
