ERJ-S14F6490U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F6490U is a 649 Ohm ±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 839 pieces available in inventory.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F6490U is determined by strict equivalence across the following critical parameters:

• Resistance value: 649 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 to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these parameters without exception. Packaging format (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility and represents a logistics consideration only.

Parameter Comparison

Engineering Selection Recommendations

For new designs and active production, CRCW1210649RFKEA (Vishay Dale) and RMCF1210FT649R (Stackpole Electronics Inc) are preferred substitutes. Both parts maintain active product status and full compliance with all electrical, mechanical, and regulatory requirements.

ERJ-14NF6490U (Panasonic) is electrically and mechanically equivalent but carries a "Not For New Designs" status. This part remains suitable for legacy system maintenance, repair, and replacement applications where the original specification must be preserved.

The ERJ-S14F6490U remains the primary choice for new designs requiring Panasonic sourcing or when anti-sulfur coating is explicitly specified as a design requirement.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210649RFKEA replace ERJ-S14F6490U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across -55°C to 155°C, and are ROHS3 compliant with MSL 1 rating. All electrical parameters (649 Ohms ±1%, 0.5W, ±100ppm/°C) are identical. The 0.004" (0.10mm) difference in seated height does not affect circuit performance or PCB assembly compatibility.

Q: What is the difference between ERJ-S14F6490U and ERJ-14NF6490U?

A: Both are Panasonic 649 Ohm ±1% 0.5W 1210 resistors with identical electrical specifications and AEC-Q200 rating. The primary difference is product status: ERJ-S14F6490U is active for new designs, while ERJ-14NF6490U is designated "Not For New Designs." The ERJ-S14 series includes anti-sulfur coating; the ERJ-14N series does not explicitly specify this feature.

Q: Does packaging format (Tape & Reel versus Cut Tape) affect compatibility?

A: No. Packaging format is a logistics and assembly consideration only. RMCF1210FT649R supplied in Cut Tape format is electrically and mechanically identical to parts supplied in Tape & Reel format. Selection between packaging options depends on assembly equipment and inventory management requirements.

Q: Are all substitute parts suitable for high-reliability automotive applications?

A: Yes. All listed substitutes carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. All operate across the full -55°C to 155°C temperature range required for automotive environments.

Q: Can I use these substitutes interchangeably on existing PCBs?

A: Yes. All substitute parts are mechanically compatible with 1210 (3225 Metric) footprints. The maximum seated height variation (0.028" for Panasonic and Stackpole versus 0.024" for Vishay) does not affect PCB assembly or component clearance in standard designs.
