ERJ-S08F5492V Equivalent & Substitute Parts

Part Overview

The ERJ-S08F5492V is a 54.9 kOhm ±1% thick film chip resistor manufactured by Panasonic Electronic Components in 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur properties. The part is currently in active production status with 750 pieces available in inventory.

Substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S08F5492V is determined by strict equivalence across the following critical parameters:

Resistance value: 54.9 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power rating: 0.25W / 1/4W (exact match required)
Package format: 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)
Termination count: 2 (exact match required)

All substitute parts listed below meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances, packaging format (Tape & Reel vs. Cut Tape), and optional features (anti-sulfur, moisture resistant) do not affect functional substitutability.

Engineering Selection Recommendations

All substitute parts listed are electrically and mechanically equivalent to the ERJ-S08F5492V and are suitable for direct replacement in circuit designs.

For new designs, select from parts with Active product status: CRCW120654K9FKEA (Vishay Dale), RC1206FR-0754K9L (YAGEO), or RMCF1206FT54K9 (Stackpole Electronics Inc). These parts offer long-term availability and manufacturer support.

The ERJ-8ENF5492V carries a "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where design continuity is required.

For automotive applications requiring AEC-Q200 qualification, select from: ERJ-S08F5492V, ERJ-8ENF5492V, CRCW120654K9FKEA, or RMCF1206FT54K9. The YAGEO RC1206FR-0754K9L does not carry explicit AEC-Q200 rating but meets all electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF5492V be used as a direct replacement for ERJ-S08F5492V?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package format, and operating temperature range. The ERJ-8ENF5492V carries "Not For New Designs" status, indicating it is a legacy part. Use only when design continuity or existing inventory constraints require it.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both packaging formats contain identical components. Tape & Reel (TR) is supplied on continuous carrier tape suitable for automated assembly equipment. Cut Tape (CT) is supplied in shorter tape segments for manual handling or lower-volume applications. Electrical and mechanical performance is identical.

Q: Are all substitute parts suitable for automotive applications?

A: ERJ-S08F5492V, ERJ-8ENF5492V, CRCW120654K9FKEA, and RMCF1206FT54K9 carry AEC-Q200 automotive qualification. RC1206FR-0754K9L does not carry explicit AEC-Q200 rating. For automotive designs requiring AEC-Q200 compliance, select from the four qualified parts.

Q: What does "Anti-Sulfur" or "Moisture Resistant" mean for substitution purposes?

A: These are optional protective features that do not affect electrical substitutability. Anti-sulfur coating protects against sulfur-containing environmental contaminants. Moisture resistant composition provides enhanced performance in humid conditions. Parts with or without these features are functionally equivalent for standard circuit applications.

Q: Can I use CRCW120654K9FKEA if my design specifies ERJ-S08F5492V?

A: Yes. CRCW120654K9FKEA meets all electrical and mechanical requirements for direct substitution. Both parts are 54.9 kOhm ±1% thick film resistors in 1206 package with identical temperature coefficients and operating ranges. The primary difference is manufacturer (Vishay Dale vs. Panasonic).

Q: Which substitute part has the best inventory availability?

A: ERJ-8ENF5492V has the highest inventory at 62,214 pieces. For active production parts, CRCW120654K9FKEA offers 20,257 pieces. Inventory levels are subject to change and should be verified with current suppliers.
