ERJ-S14F2800U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2800U is a 280 Ohm ±1% thick film chip resistor rated at 0.5W (1/2W) in a 1210 (3225 Metric) surface mount package. Manufactured by Panasonic Electronic Components, this resistor features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications operating across -55°C to 155°C. The part is currently in active production status with 1030 units in stock. Equivalent and substitute parts become necessary when the primary part faces supply constraints, lead time extensions, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2800U is determined by strict equivalence across the following critical parameters: resistance value (280 Ohms), 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), and automotive qualification (AEC-Q200). All identified substitute parts meet these requirements without exception. Substitutes are grouped by manufacturer and series designation while maintaining full electrical and mechanical compatibility. Product status variations (Active vs. Not For New Designs) are noted for design planning purposes but do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, ERJ-S14F2800U (Panasonic, Active status) and ERJ-P14F2800U (Panasonic, Active status with pulse withstanding capability) are the preferred selections. Both parts carry Active product status designation, ensuring long-term availability and manufacturer support. ERJ-P14F2800U provides additional pulse withstanding performance for applications subject to transient voltage events.

RMCF1210FT280R (Stackpole Electronics, Active status) serves as a qualified cross-manufacturer alternative, offering equivalent electrical and mechanical performance with full AEC-Q200 automotive certification and ROHS3 compliance.

ERJ-14NF2800U (Panasonic, Not For New Designs status) remains functionally equivalent and is suitable for legacy system maintenance, field replacements, and existing production runs where design revision is not planned. This part maintains full electrical and mechanical compatibility despite its discontinued design status.

All four parts satisfy identical compliance requirements: AEC-Q200 automotive qualification, ROHS3 compliance, REACH unaffected status, and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2800U be used as a direct replacement for ERJ-S14F2800U in new designs?

A: ERJ-14NF2800U meets all electrical and mechanical specifications for functional equivalence. However, it carries "Not For New Designs" status. New designs should prioritize ERJ-S14F2800U or ERJ-P14F2800U to ensure long-term supply continuity and manufacturer support.

Q: What is the difference between ERJ-P14F2800U and ERJ-S14F2800U?

A: Both parts are electrically and mechanically identical in resistance, tolerance, power rating, package, and temperature specifications. ERJ-P14F2800U includes pulse withstanding capability as an additional feature. ERJ-S14F2800U includes anti-sulfur coating. Both are Active status products suitable for new designs.

Q: Is RMCF1210FT280R a suitable substitute from a different manufacturer?

A: Yes. RMCF1210FT280R (Stackpole Electronics) provides full electrical and mechanical equivalence with identical resistance, tolerance, power rating, package dimensions, temperature coefficient, operating range, and AEC-Q200 automotive certification. Cross-manufacturer substitution is valid for this specification.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L × 0.098" W (3.20mm × 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are directly interchangeable.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All four parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 (Unlimited). They are qualified for identical automotive and industrial operating environments.

Q: What is the significance of the temperature coefficient specification?

A: All parts specify ±100ppm/°C temperature coefficient across the -55°C to 155°C operating range. This parameter ensures predictable resistance drift under thermal stress and is critical for precision circuit applications. All substitutes maintain identical thermal performance.
