ERJ-S14F19R1U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F19R1U is a 19.1 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 is designed for automotive applications with AEC-Q200 qualification and 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 updated component series, or when inventory constraints require alternative sourcing from qualified equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F19R1U is determined by strict equivalence across the following critical parameters:

• Resistance value: 19.1 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package format: 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 (Unlimited)

The ERJ-14NF19R1U qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: the ERJ-14NF19R1U is designated "Not For New Designs," indicating it represents a legacy series within Panasonic's automotive resistor portfolio.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F19R1U is the preferred selection for new designs due to its active production status and current series designation. The ERJ-14NF19R1U provides functional equivalence for applications requiring component substitution, legacy system maintenance, or inventory supplementation. However, the ERJ-14NF19R1U carries a "Not For New Designs" status, which indicates Panasonic has transitioned this series to mature/legacy support. Both parts maintain identical electrical performance, thermal characteristics, and automotive compliance certifications. Selection between these parts should be based on design phase requirements and supply chain constraints rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF19R1U be used as a direct replacement for the ERJ-S14F19R1U in automotive applications?

A: Yes. Both parts are electrically and mechanically identical, share the same 1210 package footprint, and carry AEC-Q200 automotive qualification. The ERJ-14NF19R1U is suitable for replacement in existing designs or production runs. However, new design implementations should specify the ERJ-S14F19R1U due to its active product status.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF19R1U?

A: This designation indicates that Panasonic has classified the ERJ-14N series as mature and is directing new product development toward the ERJ-S14 series. The ERJ-14NF19R1U remains fully functional and supported for existing applications and maintenance scenarios.

Q: Are there any differences in the 1210 package dimensions between these parts?

A: No. Both parts conform to identical 1210 (3225 Metric) package specifications: 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the ERJ-S14F19R1U and ERJ-14NF19R1U are ROHS3 compliant, REACH unaffected, carry MSL 1 (Unlimited) moisture sensitivity ratings, and hold AEC-Q200 automotive qualification. Thermal performance and temperature coefficient specifications are identical.

Q: What is the difference between the anti-sulfur feature on the ERJ-S14F19R1U and the standard automotive specification on the ERJ-14NF19R1U?

A: The ERJ-S14F19R1U explicitly includes anti-sulfur protection as an additional feature within the ERJ-S14 series design. The ERJ-14NF19R1U carries standard AEC-Q200 automotive qualification without this specific anti-sulfur designation. Both parts operate within the same temperature and electrical parameters for automotive environments.
