ERJ-S14F3400U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F3400U is a 340 Ohm ±1% thick film chip resistor rated at 0.5W (1/2W) in a 1210 (3225 Metric) package. This component is manufactured by Panasonic Electronic Components and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 704 units in stock.

Finding equivalent and substitute parts is necessary when the primary part becomes unavailable, when design revisions require alternative sourcing options, or when supply chain optimization requires qualified alternatives from the same or different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S14F3400U is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 340 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-14NF3400U qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is product status and feature set, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F3400U is the preferred selection for new designs due to its active product status. The ERJ-14NF3400U is electrically and mechanically equivalent and maintains full AEC-Q200 automotive qualification and ROHS3 compliance. However, the ERJ-14NF3400U carries a "Not For New Designs" designation, making it suitable only for replacement, repair, or legacy system applications where the original part specification must be maintained.

Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance, temperature characteristics, and package dimensions. Selection between these parts should be based on design phase requirements and supply availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3400U be used as a direct replacement for ERJ-S14F3400U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF3400U is designated "Not For New Designs." New designs should specify the ERJ-S14F3400U to ensure long-term supply continuity and manufacturer support.

Q: Are the package dimensions identical between these parts?

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).

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S14F3400U and ERJ-14NF3400U carry AEC-Q200 automotive qualification and are suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

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 does not include anti-sulfur protection and is not recommended for new designs. Both series meet identical electrical and mechanical specifications for this 340 Ohm 1% 1/2W 1210 package configuration.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental compliance is equivalent.
