ERJ-S14F8251U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F8251U is an 8.25 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 943 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F8251U is determined by strict equivalence across the following parameters:

• Resistance value: 8.25 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-14NF8251U meets all electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both are AEC-Q200 qualified and ROHS3 compliant.

Engineering Selection Recommendations

The ERJ-S14F8251U is the preferred selection for new designs due to its active production status and anti-sulfur feature. The ERJ-14NF8251U provides electrical and mechanical equivalence and maintains full AEC-Q200 automotive qualification and ROHS3 compliance. However, the ERJ-14NF8251U carries a "Not For New Designs" status, making it suitable only for legacy system support, field replacements, or applications where design freeze conditions permit its use.

For new automotive designs, the ERJ-S14F8251U is the specified choice. For existing systems currently using ERJ-14NF8251U components, the ERJ-S14F8251U provides a direct upgrade path with enhanced anti-sulfur protection while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF8251U be used as a direct replacement for ERJ-S14F8251U in new designs?

A: The ERJ-14NF8251U meets all electrical and mechanical parameters for direct substitution. However, it carries a "Not For New Designs" status. New designs should specify the ERJ-S14F8251U.

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

A: 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). They are mechanically interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S14F8251U and ERJ-14NF8251U are AEC-Q200 qualified and suitable for automotive applications.

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

A: The ERJ-S14F8251U belongs to the ERJ-S14 series and includes anti-sulfur protection. The ERJ-14NF8251U belongs to the ERJ-14N series without the anti-sulfur feature. Both share identical electrical specifications and package type.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.
