ERJ-S1DF6810U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF6810U is a 681 Ohm ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 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 Active in production status with 1061 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across multiple qualified suppliers. The parts listed below maintain electrical and mechanical compatibility while offering alternative sourcing options.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 681 Ohms
Tolerance: ±1%
Power rating: 0.75W
Package: 2010 (5025 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C to 155°C
Automotive qualification: AEC-Q200
RoHS compliance: ROHS3
Moisture sensitivity: MSL 1

All substitute parts listed meet these criteria. Variations in product status, inventory availability, and minor dimensional differences (height-seated) do not affect functional substitutability.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: AC2010FK-07681RL (YAGEO), CRCW2010681RFKEF (Vishay Dale), or RMCF2010FT681R (Stackpole Electronics). These three options provide current manufacturing support and full compliance with automotive AEC-Q200 and ROHS3 requirements.

The ERJ-S1DF6810U (Panasonic, Active) remains the primary choice where existing supply agreements or design validation history exists. The ERJ-12SF6810U (Panasonic, Not For New Designs) is suitable only for legacy design updates or production continuity of existing products; it should not be selected for new development.

All substitute parts are electrically and mechanically equivalent within the specified parameter tolerances and are suitable for direct PCB footprint replacement in 2010 package designs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF6810U be used in new designs? A: No. ERJ-12SF6810U carries a "Not For New Designs" status. It is available for production continuity of existing designs only. New designs should use Active-status alternatives.

Q: Are all substitute parts pin-compatible with ERJ-S1DF6810U? A: Yes. All substitute parts use the 2010 (5025 Metric) package with identical pin configuration and footprint. Direct PCB replacement is possible without layout modification.

Q: What is the significance of the anti-sulfur feature on ERJ-S1DF6810U? A: The anti-sulfur coating on the ERJ-S1DF6810U provides enhanced corrosion resistance in harsh environments. The substitute parts from YAGEO, Vishay Dale, and Stackpole Electronics do not explicitly list this feature but maintain equivalent AEC-Q200 automotive qualification and operating performance.

Q: Do all parts meet automotive qualification requirements? A: Yes. All listed parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive industry reliability and environmental standards.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Tape & Reel packaging is supplied on continuous reels for automated assembly lines. Cut Tape is supplied in smaller quantities on individual tape segments. CRCW2010681RFKEF is available in both formats. Packaging choice depends on production volume and assembly equipment compatibility, not electrical performance.

Q: Are there any thermal or environmental differences between substitute parts? A: No. All parts share identical operating temperature range (-55°C to 155°C), temperature coefficient (±100ppm/°C), and moisture sensitivity level (MSL 1). Environmental performance is equivalent across all options.
