Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF1181U are identified based on strict equivalence across the following critical parameters:

• Resistance value: 1.18 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 certification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RMCF2010FT1K18 from Stackpole Electronics Inc meets all these parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1DF1181U and RMCF2010FT1K18 are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on availability, supply chain considerations, or procurement preferences. The ERJ-S1DF1181U includes anti-sulfur coating as an additional feature. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for equivalent applications in automotive and industrial environments.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT1K18 be used as a direct replacement for ERJ-S1DF1181U?

A: Yes. Both parts share identical resistance (1.18 kOhms), tolerance (±1%), power rating (0.75W), package (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive certification (AEC-Q200). The primary difference is the anti-sulfur coating on the ERJ-S1DF1181U, which is an additional feature not present on the Stackpole part.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 2010 (5025 Metric) package with identical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and height (0.028" maximum / 0.70mm). PCB footprints and assembly processes are interchangeable.

Q: Do both parts meet automotive standards?

A: Yes. Both the ERJ-S1DF1181U and RMCF2010FT1K18 carry AEC-Q200 qualification and are suitable for automotive applications across the specified operating temperature range of -55°C to 155°C.

Q: What is the significance of the anti-sulfur coating on the ERJ-S1DF1181U?

A: The anti-sulfur coating on the Panasonic part provides additional protection in environments with sulfur-containing compounds. If the application environment does not require this specific protection, the Stackpole part is functionally equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.
