Equivalent & Substitute Parts for ERJ-S14F2610U

Part Overview

The ERJ-S14F2610U is a 261 Ohms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This part 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 1096 units in stock.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the same package footprint and performance ratings. Alternative sources become necessary for supply chain continuity, inventory availability, or design flexibility across qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2610U is determined by strict equivalence across the following critical parameters:

• Resistance value: 261 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package footprint: 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 maintain these electrical and mechanical specifications. Variations in product status, inventory levels, or manufacturer-specific features (such as anti-sulfur coating) do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S14F2610U (Panasonic, Active status) and CRCW1210261RFKEA (Vishay Dale, Active status) are the preferred selections. Both parts maintain active production status and full compliance with AEC-Q200 automotive qualification and ROHS3 requirements.

The ERJ-14NF2610U (Panasonic) is marked as "Not For New Designs" and should be used only for legacy system maintenance or existing design continuity where supply from active alternatives is constrained.

All three parts are functionally equivalent across the specified electrical and mechanical parameters. Selection between active alternatives may be based on supply chain availability, inventory position, or established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2610U replace ERJ-S14F2610U in new designs?

A: ERJ-14NF2610U is marked "Not For New Designs" by the manufacturer. While electrically and mechanically equivalent, new designs should specify either ERJ-S14F2610U or CRCW1210261RFKEA to ensure long-term supply continuity.

Q: Are there physical differences between these parts?

A: All parts use the 1210 (3225 Metric) package footprint. The CRCW1210261RFKEA has a maximum seated height of 0.024" (0.60mm) compared to 0.028" (0.70mm) for the Panasonic variants. This difference is within standard PCB assembly tolerances and does not affect interchangeability.

Q: Do all substitute parts meet automotive requirements?

A: Yes. All listed parts carry AEC-Q200 qualification and ROHS3 compliance, meeting automotive-grade reliability and environmental standards.

Q: What is the significance of the anti-sulfur feature on ERJ-S14F2610U?

A: The anti-sulfur coating on ERJ-S14F2610U provides enhanced corrosion resistance in high-sulfur environments. This feature is not specified on ERJ-14NF2610U or CRCW1210261RFKEA. For applications requiring anti-sulfur protection, ERJ-S14F2610U is the specified choice.

Q: Are these parts interchangeable at the PCB assembly level?

A: Yes. All parts share identical electrical specifications (261 Ohms ±1%, 0.5W, ±100ppm/°C, -55°C ~ 155°C), identical package footprint (1210), and identical termination configuration (2 terminations). PCB layouts and assembly processes require no modification for substitution.
