ERJ-S03F3831V Equivalent & Substitute Parts

Part Overview

The ERJ-S03F3831V is a 3.83 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. 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 across qualified manufacturers is required for procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F3831V is determined by strict equivalence across the following parameters: resistance value (3.83 kOhms), tolerance (±1%), power rating (0.1W), package format (0603 / 1608 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and termination count (2). All qualified substitutes maintain identical electrical specifications and physical package dimensions within acceptable tolerances. Compliance certifications (ROHS3, MSL 1) and manufacturing status (active) are consistent across all listed alternatives. Substitutes are grouped by manufacturer while maintaining full parameter equivalence.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the ERJ-S03F3831V. Selection among qualified alternatives should be based on procurement availability, lead time, and inventory levels. The ERJ-3EKF3831V (Panasonic) offers the highest inventory availability at 249,412 units and maintains identical specifications with AEC-Q200 automotive qualification. RC0603FR-073K83L (YAGEO) provides the largest stock position at 455,833 units. CRCW06033K83FKEA (Vishay Dale) and RMCF0603FT3K83 (Stackpole Electronics Inc) are suitable alternatives with substantial inventory levels. All parts are ROHS3 compliant, active in production status, and carry MSL 1 rating. Physical dimensions remain within acceptable tolerances across all manufacturers.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF3831V be used as a direct replacement for ERJ-S03F3831V? A: Yes. Both parts are manufactured by Panasonic Electronic Components with identical resistance (3.83 kOhms), tolerance (±1%), power rating (0.1W), package format (0603), and operating temperature range (-55°C ~ 155°C). The primary difference is series designation (ERJ-3EK vs. ERJ-S03), with ERJ-3EKF3831V offering significantly higher inventory availability.

Q: Are YAGEO AC0603FR-073K83L and RC0603FR-073K83L interchangeable? A: Yes. Both YAGEO parts share identical electrical specifications and 0603 package format. RC0603FR-073K83L has substantially higher inventory (455,833 units vs. 22,296 units) and represents the preferred selection for availability.

Q: Do all substitute parts support automotive applications? A: ERJ-S03F3831V, ERJ-3EKF3831V, AC0603FR-073K83L, CRCW06033K83FKEA, and RMCF0603FT3K83 carry AEC-Q200 automotive qualification. CR0603-FX-3831ELF and RC0603FR-073K83L do not list AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, select from the five qualified alternatives.

Q: What is the significance of MSL 1 rating? A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. All listed parts carry MSL 1 rating, eliminating moisture-related handling and storage constraints.

Q: Are there physical dimension variations among substitute parts? A: Nominal package dimensions are 0603 (1608 Metric) across all parts. CRCW06033K83FKEA and RMCF0603FT3K83 show minor dimensional variations (height 0.50mm vs. 0.55mm, length 1.55mm vs. 1.60mm) within acceptable PCB assembly tolerances. These variations do not affect functional compatibility.
