ERJ-S08F2803V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F2803V is a 280 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for applications requiring high reliability in automotive and industrial environments. The part is currently in active production status with 978 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements mandate alternative qualified suppliers, or when inventory constraints require sourcing from multiple manufacturers while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F2803V is determined by strict equivalence across the following critical parameters:

Resistance value: 280 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W / 1/4W (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)
Packaging format: Tape & Reel (exact match required)
RoHS compliance: ROHS3 Compliant (exact match required)
Moisture sensitivity: MSL 1 (exact match required)

All four substitute parts listed meet these criteria and are therefore direct functional equivalents suitable for replacement in applications currently using the ERJ-S08F2803V.

Engineering Selection Recommendations

For new designs and ongoing production, CRCW1206280KFKEA (Vishay Dale), RC1206FR-07280KL (YAGEO), and RMCF1206FT280K (Stackpole Electronics Inc) are preferred substitutes, as all three maintain active product status with full manufacturing support and availability.

ERJ-8ENF2803V (Panasonic Electronic Components) is functionally equivalent but carries "Not For New Designs" status, indicating the manufacturer has transitioned this part to legacy support. This part remains suitable for replacement in existing production runs or field service applications where the original ERJ-S08F2803V is unavailable, provided inventory constraints do not apply.

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification (where specified), and identical electrical performance within the stated operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF2803V be used as a direct replacement for ERJ-S08F2803V?

A: Yes. Both parts share identical electrical specifications (280 kOhms ±1%, 0.25W, ±100ppm/°C) and mechanical package (1206). However, ERJ-8ENF2803V carries "Not For New Designs" status. Use this part only when ERJ-S08F2803V is unavailable or for field service applications.

Q: Are there differences in physical dimensions between substitute parts?

A: Minor variations exist in maximum seated height. ERJ-S08F2803V and RMCF1206FT280K both measure 0.028" (0.70mm) maximum height, while CRCW1206280KFKEA measures 0.024" (0.60mm) and RC1206FR-07280KL measures 0.026" (0.65mm). All parts fit within standard 1206 package specifications and are mechanically compatible with existing PCB layouts.

Q: Do all substitute parts carry automotive qualification?

A: ERJ-S08F2803V, ERJ-8ENF2803V, CRCW1206280KFKEA, and RMCF1206FT280K all carry AEC-Q200 automotive qualification. RC1206FR-07280KL does not list AEC-Q200 rating but features moisture-resistant thick film construction suitable for industrial applications.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur coating (ERJ-S08F2803V) protects against sulfur-containing atmospheric contaminants common in automotive environments. Moisture-resistant construction (RC1206FR-07280KL) provides protection against humidity and moisture ingress. Both are valid protective mechanisms for different application environments.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 280 kOhms ±1% 0.25W 1206 package. No design modifications are required for substitution. Verify compliance certifications (AEC-Q200, RoHS) match your application requirements before final selection.
