ERJ-S14F1052U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1052U is a 10.5 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package. 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.

Substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative sourcing options, or when inventory constraints require qualified alternatives from the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1052U is determined by strict equivalence across the following parameters:

• Resistance value: 10.5 kOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The ERJ-14NF1052U meets all substitution criteria and is qualified as a direct equivalent. This part maintains identical electrical specifications and package dimensions while originating from the ERJ-14N series within the same manufacturer portfolio.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1052U is the preferred selection for new designs due to its active production status. The ERJ-14NF1052U is electrically and mechanically equivalent and remains available for existing designs or when primary part availability is constrained. However, the ERJ-14NF1052U carries a "Not For New Designs" status, indicating that Panasonic has transitioned this series to legacy support.

Both parts maintain identical compliance certifications including AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating. Selection between these parts should be based on design phase requirements and supply chain availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1052U be used as a direct replacement for ERJ-S14F1052U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and maintain identical electrical specifications, tolerance, power rating, and operating temperature range. The package dimensions and termination count are identical, enabling direct PCB substitution.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF1052U?

A: This designation indicates that Panasonic has moved the ERJ-14N series to legacy support status. While the part remains available and fully functional, new product designs should prioritize the ERJ-S14F1052U from the active ERJ-S14 series to ensure long-term supply continuity.

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

A: The ERJ-S14F1052U includes explicit anti-sulfur protection in its specification. The ERJ-14NF1052U does not list this feature. Both parts meet AEC-Q200 standards, but applications requiring confirmed anti-sulfur protection should specify the ERJ-S14F1052U.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use identical 1210 (3225 Metric) packages with matching footprints, pad layouts, and height specifications. No PCB redesign is required for substitution.

Q: What compliance certifications apply to both parts?

A: Both the ERJ-S14F1052U and ERJ-14NF1052U are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (unlimited) moisture sensitivity ratings.
