Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF3401U is determined by strict equivalence across the following parameters:

• Resistance value: 3.4 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

The RMCF2010FT3K40 from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1DF3401U and RMCF2010FT3K40 are active production parts with identical electrical and mechanical specifications. Selection between these parts may be based on:

• Inventory availability: RMCF2010FT3K40 has 8863 pieces in stock versus 830 pieces for ERJ-S1DF3401U
• Supply chain lead times and procurement preferences
• Manufacturer qualification requirements specific to your application
• Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT3K40 be used as a direct replacement for ERJ-S1DF3401U?

A: Yes. Both parts share identical resistance (3.4 kOhms), tolerance (±1%), power rating (0.75W), package (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Mechanical dimensions and termination count are also identical.

Q: Are there differences in anti-sulfur coating between these parts?

A: The ERJ-S1DF3401U is specified with anti-sulfur coating. The RMCF2010FT3K40 specification provided does not explicitly list anti-sulfur coating. This difference should be evaluated against your application requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Both have MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the 2010 package designation?

A: The 2010 package (5025 Metric) specifies the physical dimensions of 5.00mm length by 2.50mm width with a maximum seated height of 0.70mm. This standardized package ensures mechanical and electrical compatibility between parts from different manufacturers.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided your design does not specifically require the anti-sulfur coating feature of the ERJ-S1DF3401U. Both parts have identical footprints, termination configuration, and electrical performance within the specified operating range.
