Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF66R5U is determined by strict equivalence across the following parameters:

• Resistance value: 66.5 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

The RMCF2010FT66R5 from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT66R5 be used as a direct replacement for ERJ-S1DF66R5U?

A: Yes. Both parts share identical resistance values (66.5 Ohms), tolerance (±1%), power rating (0.75W), package format (2010), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical dimensions and termination count are identical.

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

A: The ERJ-S1DF66R5U is specified with anti-sulfur protection. The RMCF2010FT66R5 specification does not explicitly list this feature. This distinction should be evaluated against application requirements.

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

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected.

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

A: Yes. Identical package format (2010), dimensions (5.00mm x 2.50mm), and termination count (2) ensure mechanical and electrical interchangeability in PCB layouts designed for either part number.
