ERJ-S1DF5111U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF5111U is a 5.11 kOhms ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. Manufactured by Panasonic Electronic Components, this resistor features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for automotive and harsh environment applications. The part is currently in active production status with 623 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across multiple suppliers, or when inventory constraints necessitate alternative sourcing from qualified manufacturers offering equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF5111U is determined by strict equivalence across the following parameters:

• Resistance value: 5.11 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 and are therefore electrically and mechanically interchangeable with the primary part in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1DF5111U (Panasonic), CRCW20105K11FKEF (Vishay Dale), or RMCF2010FT5K11 (Stackpole Electronics). All three maintain full compliance with ROHS3 and AEC-Q200 automotive qualification standards.

The ERJ-12SF5111U carries a Not For New Designs status and should be used only in legacy design maintenance or when existing inventory constraints require its use. This part remains electrically and mechanically equivalent but is not recommended for new product development.

All four parts are REACH Unaffected and classified under ECCN EAR99, with identical HTSUS coding (8533.21.0030), confirming their regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF5111U be used in new designs? A: No. ERJ-12SF5111U carries a Not For New Designs status. Use ERJ-S1DF5111U, CRCW20105K11FKEF, or RMCF2010FT5K11 for new product development.

Q: Are all substitute parts mechanically identical? A: Yes. All parts share identical package dimensions (2010 / 5025 Metric), footprint, and height specifications (0.028" maximum seated height). They are pin-compatible and footprint-compatible.

Q: What determines substitution eligibility? A: Substitution requires matching resistance value (5.11 kOhms), tolerance (±1%), power rating (0.75W), package type (2010), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200).

Q: Are there differences in anti-sulfur coating? A: The ERJ-S1DF5111U explicitly includes anti-sulfur coating. The ERJ-12SF5111U does not list this feature. For applications requiring anti-sulfur protection, verify coating specifications with the manufacturer before substitution.

Q: Can these parts be used interchangeably in automotive applications? A: Yes. All parts carry AEC-Q200 automotive qualification and operate across the identical temperature range (-55°C ~ 155°C), making them suitable for automotive circuit applications.

Q: What is the difference between the manufacturers? A: ERJ-S1DF5111U and ERJ-12SF5111U are Panasonic products. CRCW20105K11FKEF is manufactured by Vishay Dale. RMCF2010FT5K11 is manufactured by Stackpole Electronics. All meet identical electrical and mechanical specifications.
