ERJ-S14F4640U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F4640U is a 464 Ohms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 786 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits equivalent alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4640U is determined by strict equivalence across the following parameters:

• Resistance value: 464 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these criteria. Variations in product status, inventory availability, and minor dimensional tolerances (height-seated maximum) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

For new designs, ERJ-S14F4640U (Panasonic, Active status) and CRCW1210464RFKEA (Vishay Dale, Active status) are the preferred selections. Both parts carry active product status and meet all automotive and compliance requirements.

ERJ-14NF4640U (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance, repair, or replacement applications where the original part number must be maintained.

The CRCW1210464RFKEA variant offers a slightly reduced maximum seated height (0.024" versus 0.028"), which may provide design flexibility in space-constrained applications while maintaining full electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4640U be used in new designs? A: No. ERJ-14NF4640U carries "Not For New Designs" status. Use ERJ-S14F4640U or CRCW1210464RFKEA for new designs.

Q: Are all three parts mechanically interchangeable? A: Yes. All parts use the 1210 (3225 Metric) package with identical footprints. The CRCW1210464RFKEA has a lower maximum seated height (0.024" vs 0.028"), which does not affect PCB assembly compatibility.

Q: Do all substitute parts meet automotive requirements? A: Yes. All three parts carry AEC-Q200 qualification and are suitable for automotive applications.

Q: What is the difference between ERJ-S14F4640U and ERJ-14NF4640U? A: The primary difference is product status. ERJ-S14F4640U is active; ERJ-14NF4640U is not recommended for new designs. Both have identical electrical specifications and the same anti-sulfur or standard thick film composition. ERJ-S14F4640U includes anti-sulfur coating.

Q: Are all parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can CRCW1210464RFKEA replace ERJ-S14F4640U in existing assemblies? A: Yes. Electrical and mechanical specifications are identical. The lower seated height of CRCW1210464RFKEA does not affect compatibility with existing PCB designs.
