Equivalent & Substitute Parts for ERJ-S03F2873V

Part Overview

The ERJ-S03F2873V is a 287 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in 0603 (1608 Metric) package format with 0.1W power rating. This component is rated for automotive applications under AEC-Q200 standard with anti-sulfur properties and operates across -55°C to 155°C temperature range. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from multiple qualified manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F2873V is determined by strict equivalence across the following parameters:

• Resistance value: 287 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

All substitute parts listed meet these core electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within the 0603 package specification and differences in optional features (anti-sulfur coating, moisture resistance) do not affect functional substitutability for this resistance value and power rating combination.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance equivalent to the primary ERJ-S03F2873V component. Selection among these alternatives should be based on:

Automotive AEC-Q200 Rated Options: ERJ-3EKF2873V (Panasonic), CRCW0603287KFKEA (Vishay Dale), and RMCF0603FT287K (Stackpole Electronics Inc) carry explicit AEC-Q200 automotive qualification ratings matching the primary part specification.

Moisture Resistant Feature: AC0603FR-07287KL, CR0603-FX-2873ELF, and RC0603FR-07287KL include moisture resistant properties in addition to core electrical specifications.

Supply Availability: ERJ-3EKF2873V offers the highest inventory level (196,528 pcs), followed by RMCF0603FT287K (110,513 pcs) and RC0603FR-07287KL (44,200 pcs), providing flexibility for volume requirements.

Anti-Sulfur Feature: The primary part ERJ-S03F2873V includes anti-sulfur coating; this feature is not present in substitute options but does not affect electrical performance for standard applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF2873V directly replace ERJ-S03F2873V in automotive applications?

A: Yes. Both parts are manufactured by Panasonic, rated for AEC-Q200 automotive applications, and share identical electrical specifications (287 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C). The primary difference is the series designation (ERJ-3EK versus ERJ-S03) and the absence of anti-sulfur coating in the ERJ-3EKF variant, which does not affect functional compatibility.

Q: Are YAGEO AC0603FR-07287KL and RC0603FR-07287KL interchangeable?

A: Both YAGEO parts meet the core electrical and mechanical requirements for substitution. AC0603FR-07287KL carries AEC-Q200 automotive rating, while RC0603FR-07287KL does not. Selection depends on whether automotive qualification is required for the application.

Q: What is the significance of the 0603 package specification across all parts?

A: The 0603 (1608 Metric) package designation ensures mechanical and footprint compatibility across all listed parts. Physical dimension variations within this package class (such as length 0.061" to 0.063" and height 0.020" to 0.022") remain within standard PCB assembly tolerances and do not affect placement or soldering processes.

Q: Why do some substitute parts lack AEC-Q200 rating?

A: CR0603-FX-2873ELF (Bourns) and RC0603FR-07287KL (YAGEO) are qualified for general industrial and commercial applications. These parts are suitable for non-automotive designs or applications where automotive qualification is not required. For automotive designs, select parts with explicit AEC-Q200 designation.

Q: Does the absence of anti-sulfur coating in substitute parts affect reliability?

A: Anti-sulfur coating is an optional feature for enhanced environmental protection in high-sulfur exposure environments. For standard operating conditions, substitute parts without this coating maintain equivalent electrical performance and reliability. Application environment assessment determines whether this feature is necessary.

Q: What inventory considerations apply when selecting substitutes?

A: ERJ-3EKF2873V and RMCF0603FT287K offer significantly higher inventory levels, reducing lead time risk for volume production. AC0603FR-07287KL and CRCW0603287KFKEA have lower inventory; availability should be confirmed for time-sensitive projects.
