ERJ-S14F10R7U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F10R7U is a 10.7 Ohm ±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 823 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 from alternative manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F10R7U is determined by strict equivalence across the following parameters:

• Resistance value: 10.7 Ohms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200
• Termination count: 2
• Physical dimensions: 3.20mm × 2.50mm footprint

The ERJ-14NF10R7U from Panasonic meets all electrical and mechanical parameters required for direct substitution. This part maintains identical resistance, tolerance, power rating, package, and thermal specifications while providing equivalent AEC-Q200 automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F10R7U is the preferred selection for new designs due to its active production status. This part carries full manufacturer support and is recommended for applications requiring long-term component availability and supply chain stability.

The ERJ-14NF10R7U is classified as "Not For New Designs" and should be used only in legacy system maintenance, repair, or retrofit applications where the original part specification must be maintained. This substitute provides complete electrical and mechanical equivalence but lacks the production continuity assurance of the active part.

Both parts meet identical AEC-Q200 automotive qualification requirements and ROHS3 compliance standards, ensuring regulatory compatibility across automotive and industrial applications operating within the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF10R7U be used as a direct replacement for ERJ-S14F10R7U in new designs?

A: No. While the ERJ-14NF10R7U meets all electrical and mechanical specifications, its "Not For New Designs" status indicates discontinued production. New designs should specify the ERJ-S14F10R7U to ensure long-term supply availability.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical footprint dimensions of 3.20mm length × 2.50mm width and maximum seated height of 0.70mm. PCB layout and assembly processes require no modification.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the ERJ-S14F10R7U and ERJ-14NF10R7U carry AEC-Q200 automotive qualification and operate across the identical temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient.

Q: What is the difference between these Panasonic resistor series?

A: The ERJ-S14 series (main part) represents the current production line with anti-sulfur protection. The ERJ-14N series (substitute) is the legacy production line. Both deliver equivalent electrical performance and thermal stability for the specified 10.7 Ohm ±1% 0.5W application.

Q: Are moisture sensitivity levels the same?

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