ERJ-S03F9311V Equivalent & Substitute Parts

Part Overview

The ERJ-S03F9311V is a 9.31 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).

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F9311V is determined by strict equivalence across the following parameters:

• Resistance value: 9.31 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 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)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed below meet these criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel vs. Cut Tape) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the ERJ-S03F9311V. Selection among these equivalents should be based on:

Automotive AEC-Q200 Certification: ERJ-3EKF9311V, CRCW06039K31FKEA, and RMCF0603FT9K31 carry explicit AEC-Q200 automotive qualification. The ERJ-S03F9311V includes anti-sulfur properties in addition to AEC-Q200 rating.

Availability and Lead Time: RC0603FR-079K31L from YAGEO offers the highest inventory level (235,823 pcs), followed by CRCW06039K31FKEA from Vishay Dale (71,353 pcs). ERJ-3EKF9311V from Panasonic provides 58,511 pcs in stock.

Packaging Format: CRCW06039K31FKEA is supplied in Cut Tape (CT) & Digi-Reel format, while all other substitutes use standard Tape & Reel (TR) packaging.

Moisture Resistance Features: AC0603FR-079K31L, CR0603-FX-9311ELF, and RC0603FR-079K31L explicitly specify moisture-resistant properties. The ERJ-S03F9311V includes anti-sulfur protection.

All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF9311V be used as a direct replacement for ERJ-S03F9311V?

A: Yes. Both are Panasonic thick film 0603 resistors with 9.31 kOhms ±1% resistance, 0.1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is the series designation (ERJ-3EK vs. ERJ-S03). ERJ-3EKF9311V has higher inventory availability (58,511 pcs vs. 805 pcs).

Q: Are YAGEO AC0603FR-079K31L and RC0603FR-079K31L interchangeable?

A: Both YAGEO parts meet all electrical and mechanical specifications for substitution. AC0603FR-079K31L carries AEC-Q200 automotive qualification, while RC0603FR-079K31L does not. RC0603FR-079K31L has significantly higher inventory (235,823 pcs vs. 38,313 pcs). Selection depends on automotive certification requirements for your application.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel packaging provides the same components but in shorter tape segments with reel options. Both formats are compatible with standard SMD assembly equipment. CRCW06039K31FKEA uses Cut Tape & Digi-Reel format.

Q: Do all substitute parts support automotive applications?

A: ERJ-3EKF9311V, CRCW06039K31FKEA, and RMCF0603FT9K31 carry AEC-Q200 automotive qualification. AC0603FR-079K31L and CR0603-FX-9311ELF do not list AEC-Q200 rating. RC0603FR-079K31L does not carry automotive certification. For automotive applications requiring AEC-Q200 compliance, use ERJ-3EKF9311V, CRCW06039K31FKEA, or RMCF0603FT9K31.

Q: Are there any physical dimension variations among substitute parts?

A: Minor variations exist within standard tolerances. CRCW06039K31FKEA and RMCF0603FT9K31 have slightly different length and height specifications compared to the primary part and other substitutes, but these differences remain within 0603 package class tolerances and do not affect PCB footprint compatibility or assembly.

Q: What is MSL 1 and why is it important?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture exposure controls. All listed parts carry MSL 1 rating, meaning they do not require special dry-pack storage or baking procedures prior to assembly, simplifying logistics and handling.
