ERJ-S14F3401U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F3401U is a 3.4 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 with 624 units available in stock.

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

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F3401U is determined by strict equivalence across the following parameters:

• Resistance value: 3.4 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package type: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF3401U meets all substitution criteria and is qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F3401U is the preferred selection for new designs due to its active product status. The ERJ-14NF3401U is electrically and mechanically equivalent and carries identical AEC-Q200 automotive qualification and ROHS3 compliance. However, the ERJ-14NF3401U is designated "Not For New Designs," indicating Panasonic has transitioned this series to end-of-life status.

Selection between these parts should be based on design phase and supply chain requirements. For active development and production qualification, the ERJ-S14F3401U is the appropriate choice. The ERJ-14NF3401U may be used only in legacy designs or when supply constraints of the primary part necessitate substitution in existing production lines.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3401U be used as a direct replacement for ERJ-S14F3401U in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical electrical specifications (3.4 kOhms ±1%, 0.5W), and use the same 1210 package. They are mechanically and electrically interchangeable. However, the ERJ-14NF3401U is not recommended for new designs.

Q: What is the difference between the ERJ-S14 and ERJ-14N series?

A: The ERJ-S14 series includes anti-sulfur protection and is in active production. The ERJ-14N series lacks anti-sulfur protection and is designated not for new designs. Both meet AEC-Q200 standards and share identical electrical and thermal characteristics.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts use identical 1210 (3225 Metric) packaging and MSL 1 moisture sensitivity rating, making them compatible with standard surface mount assembly processes without additional handling requirements.

Q: What compliance certifications apply to both parts?

A: Both ERJ-S14F3401U and ERJ-14NF3401U are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry AEC-Q200 automotive qualification.
