ERJ-S14F39R2U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F39R2U is a 39.2 Ohm ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 741 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative sourcing, or when supply chain optimization requires qualified alternatives from different manufacturers while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F39R2U is determined by strict equivalence across the following parameters:

• Resistance value: 39.2 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package designation: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All qualified substitutes meet these parameters without exception. Physical dimensions and termination count remain constant across all equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S14F39R2U (Panasonic), CRCW121039R2FKEA (Vishay Dale), or RMCF1210FT39R2 (Stackpole Electronics Inc). All three maintain identical electrical specifications and AEC-Q200 automotive qualification.

The ERJ-14NF39R2U carries a "Not For New Designs" status and should be used only for legacy design maintenance or existing production continuity where the original part specification is locked.

All substitute parts are ROHS3 compliant with MSL 1 rating, confirming compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF39R2U be used in place of ERJ-S14F39R2U in new designs?

A: No. The ERJ-14NF39R2U carries a "Not For New Designs" status. Use only for legacy production or existing designs where the original specification is established. For new designs, select from active-status alternatives.

Q: Are all substitute parts electrically identical to the main part?

A: Yes. All listed substitutes match the ERJ-S14F39R2U in resistance (39.2 Ω), tolerance (±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Q: Do physical dimensions differ between manufacturers?

A: All parts use the 1210 (3225 Metric) package with identical length (3.20mm) and width (2.50mm). Height-seated maximum varies slightly: Panasonic and Stackpole specify 0.028" (0.70mm), while Vishay Dale specifies 0.024" (0.60mm). This variation remains within standard PCB assembly tolerances.

Q: Are all substitutes automotive-qualified?

A: Yes. All listed parts meet AEC-Q200 automotive qualification standards.

Q: What is the difference between ERJ-S14 and ERJ-14N series?

A: Both are Panasonic thick film chip resistors with identical electrical specifications. The ERJ-S14 series is current production (Active status), while the ERJ-14N series is legacy (Not For New Designs status).

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitutes are footprint-compatible in the 1210 package and meet identical electrical and thermal specifications, allowing direct substitution without circuit redesign.
