ERJ-S14F16R5U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F16R5U is a 16.5 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 758 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 product series while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F16R5U is determined by strict equivalence across the following parameters:

• Resistance value: 16.5 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 ~ 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The ERJ-14NF16R5U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product lifecycle status: ERJ-S14F16R5U is active production, while ERJ-14NF16R5U is designated "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S14F16R5U is the preferred selection due to active production status and manufacturer support continuity.

The ERJ-14NF16R5U is electrically and mechanically equivalent and suitable for legacy system maintenance, field replacements, or applications where existing inventory must be utilized. However, this part carries "Not For New Designs" designation, indicating Panasonic has transitioned this series to obsolescence. Selection of ERJ-14NF16R5U should be limited to situations where design freeze or supply chain constraints necessitate use of existing stock.

Both parts maintain identical compliance certifications: AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating. Thermal and electrical performance characteristics are equivalent across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF16R5U be used as a direct replacement for ERJ-S14F16R5U in production assemblies?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The primary difference is product lifecycle status. ERJ-14NF16R5U is suitable for replacement applications but not recommended for new design implementations.

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

A: The ERJ-S14F16R5U explicitly includes anti-sulfur protection in its specification. The ERJ-14NF16R5U specification does not list this feature. For applications requiring anti-sulfur protection, ERJ-S14F16R5U is the appropriate selection.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-S14F16R5U and ERJ-14NF16R5U carry AEC-Q200 automotive qualification and are suitable for automotive applications within the specified temperature and power parameters.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF16R5U?

A: This designation indicates Panasonic has discontinued active development and long-term support for this product series. While existing inventory remains available and functional, the manufacturer recommends transitioning to active series (such as ERJ-S14) for new product development to ensure supply continuity and manufacturer support.

Q: Are the package dimensions identical between both parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical footprint dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB layout and assembly processes require no modification.
