Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF2100U is determined by strict equivalence across the following parameters:

• Resistance value: 210 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package format: 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

Parts meeting all these criteria are classified as direct equivalents and may be used interchangeably in applications designed for the ERJ-S1DF2100U.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT210R manufactured by Stackpole Electronics Inc is a direct equivalent to the ERJ-S1DF2100U. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts may be based on availability, supply chain considerations, or procurement preferences, as both maintain active production status and meet all automotive and environmental compliance requirements.

The ERJ-S1DF2100U includes anti-sulfur coating as an additional feature. Applications requiring this specific feature should retain the Panasonic component. For applications where anti-sulfur coating is not a design requirement, the RMCF2010FT210R provides equivalent performance.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT210R replace ERJ-S1DF2100U in automotive applications?

A: Yes. Both components carry AEC-Q200 automotive qualification, operate across the identical temperature range (-55°C ~ 155°C), and meet ROHS3 compliance. Electrical and mechanical specifications are equivalent.

Q: What is the difference between these two resistors?

A: The primary difference is the anti-sulfur coating feature present in the ERJ-S1DF2100U. The RMCF2010FT210R does not specify this coating. All other electrical, mechanical, and compliance parameters are identical.

Q: Are the package dimensions identical?

A: Yes. Both components use the 2010 (5025 Metric) package with identical dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable on PCBs designed for this footprint.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on design requirements. If anti-sulfur protection is necessary, specify ERJ-S1DF2100U. If this feature is not required, either component is acceptable based on availability and supply chain factors.
