ERJ-S1DF1872U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF1872U is a 18.7 kOhms ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. Manufactured by Panasonic Electronic Components, this component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently in active production status with 680 units in stock.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF1872U is determined by strict equivalence across the following parameters:

• Resistance value: 18.7 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 identified substitute parts meet these criteria across all electrical and mechanical specifications. Substitution is valid regardless of manufacturer or product status, provided these parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S1DF1872U (Primary Selection): Active product status with full manufacturing support. Recommended for new designs requiring long-term availability and supply chain stability.

CRCW201018K7FKEF (Preferred Substitute): Manufactured by Vishay Dale with active product status. Highest inventory availability (8897 units) and equivalent electrical and mechanical specifications. Suitable for immediate substitution in existing designs or new applications.

ERJ-12SF1872U (Legacy Substitute): Panasonic manufacture with "Not For New Designs" status. Acceptable for sustaining production or retrofit applications where supply of the primary part is unavailable. Higher inventory (5439 units) may provide short-term sourcing advantage despite discontinued status.

All three parts satisfy automotive AEC-Q200 qualification and ROHS3 compliance requirements. Selection should prioritize active product status for new design implementations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1872U be used as a direct replacement for ERJ-S1DF1872U?

A: Yes. Both parts share identical electrical specifications (18.7 kOhms ±1%, 0.75W), mechanical package (2010), temperature characteristics (±100ppm/°C, -55°C to 155°C), and automotive qualification (AEC-Q200). The primary difference is product status; ERJ-12SF1872U is marked "Not For New Designs" but remains functionally equivalent.

Q: What is the difference between ERJ-S1DF1872U and CRCW201018K7FKEF?

A: Both parts are electrically and mechanically identical across all specified parameters. The difference is manufacturer: Panasonic versus Vishay Dale. CRCW201018K7FKEF maintains active product status and higher inventory availability.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C to 155°C), making them suitable for automotive and industrial environments.

Q: Does package compatibility affect substitution?

A: No. All parts use the 2010 (5025 Metric) surface mount package with identical dimensions (0.197" L x 0.098" W, 0.028" maximum seated height) and two terminations. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer is not actively promoting the part for new applications and may discontinue production. Existing inventory remains available for sustaining production or retrofit use, but new designs should prioritize parts with active status.
