ERJ-S14F25R5U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F25R5U is a 25.5 Ohm ±1% thick film chip resistor manufactured by Panasonic Electronic Components. This 1210 (3225 Metric) package resistor is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur coating. The part is currently in active production status with 939 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to alternative series, or when inventory constraints require sourcing from alternative product lines that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F25R5U is determined by strict equivalence across the following parameters:

• Resistance value: 25.5 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• 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-14NF25R5U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. This part belongs to the ERJ-14N series and carries an identical resistance, tolerance, power rating, package configuration, and environmental specifications. The primary distinction is product status classification.

Engineering Selection Recommendations

The ERJ-S14F25R5U is the preferred selection for new designs due to its active product status. This designation indicates ongoing manufacturing support, quality assurance, and long-term availability from Panasonic Electronic Components.

The ERJ-14NF25R5U carries a "Not For New Designs" status, which reflects its position in the product lifecycle. However, this part maintains full electrical and mechanical equivalence with the main part and carries identical AEC-Q200 automotive qualification and ROHS3 compliance certifications. The ERJ-14NF25R5U is suitable for replacement applications, legacy system support, and situations where inventory availability of the primary part is constrained.

Both parts are manufactured by Panasonic Electronic Components and meet all automotive and environmental compliance requirements specified for this resistor category.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF25R5U be used as a direct replacement for ERJ-S14F25R5U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and share identical electrical specifications (25.5 Ohms ±1%, 0.5W), temperature characteristics (±100ppm/°C, -55°C ~ 155°C operating range), and package configuration (1210 / 3225 Metric). The parts are mechanically and electrically interchangeable.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF25R5U?

A: This designation indicates that Panasonic Electronic Components is not recommending this part for new product development. However, the part remains available for existing applications, replacement inventory, and legacy system support. All performance and compliance specifications remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERJ-S14F25R5U and ERJ-14NF25R5U are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the package size for these resistors?

A: Both parts use the 1210 package (3225 Metric), with dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Are there inventory differences between the main part and substitute?

A: Yes. The ERJ-S14F25R5U has 939 units in stock, while the ERJ-14NF25R5U has 23637 units available. The substitute part offers significantly higher inventory availability.
