ERJ-S1DF1871U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF1871U is a 1.87 kOhms ±1% 0.75W thick film chip resistor in 2010 (5025 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 active in production with 711 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging formats are required, or when design flexibility across qualified manufacturers is needed while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF1871U is determined by strict equivalence across the following parameters:

• Resistance value: 1.87 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 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 substitute parts listed meet these criteria. Packaging format (Tape & Reel vs. Cut Tape) represents a logistics variation and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the ERJ-S1DF1871U and meet identical specifications for automotive applications.

For new designs, select from parts with Active product status: CRCW20101K87FKEF (Vishay Dale) or RMCF2010FT1K87 (Stackpole Electronics Inc). Both maintain full AEC-Q200 qualification and ROHS3 compliance.

The ERJ-12SF1871U (Panasonic) carries a "Not For New Designs" status and should be used only for legacy design maintenance or when existing supply chain commitments require continuity with this specific part number.

Packaging format selection depends on assembly process requirements: Tape & Reel (TR) format suits automated pick-and-place operations, while Cut Tape (CT) format accommodates manual or semi-automated assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1871U be used as a direct replacement for ERJ-S1DF1871U?

A: Yes, ERJ-12SF1871U meets all electrical and mechanical specifications. However, its "Not For New Designs" status indicates it is being phased out. Use only for legacy applications or when supply continuity is required.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both formats contain identical components. Tape & Reel (TR) packaging is optimized for automated assembly lines with continuous reel feeding. Cut Tape (CT) packaging provides individual strips suitable for manual or semi-automated assembly. Electrical performance is identical.

Q: Are all substitute parts qualified for automotive applications?

A: Yes. All listed parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C ~ 155°C), meeting automotive reliability standards.

Q: Does the anti-sulfur feature of ERJ-S1DF1871U affect substitution compatibility?

A: The anti-sulfur coating is a feature of the ERJ-S1DF1871U. Substitute parts from other manufacturers do not explicitly list this feature in their specifications. For applications where anti-sulfur protection is a design requirement, verify with the component manufacturer before substitution.

Q: What is MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions and requires no special moisture control during handling or storage. All listed parts share this rating.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts are mechanically identical in the 2010 (5025 Metric) package with matching footprints, termination count (2), and maximum seated height (0.028"). PCB layout modifications are not required.
