Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF4640U is determined by strict equivalence across the following parameters: resistance value (464 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), and automotive qualification (AEC-Q200). The substitute part RMCF2010FT464R manufactured by Stackpole Electronics Inc meets all these criteria, enabling direct functional and mechanical interchangeability in automotive applications requiring this specific resistor specification.

Selection between these parts may be based on availability, supply chain considerations, or procurement preferences, as both are active products with established inventory levels. The Stackpole part currently has higher stock availability (3769 units) compared to the Panasonic part (1052 units). Both parts satisfy ROHS3 compliance and AEC-Q200 automotive qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT464R replace ERJ-S1DF4640U in automotive applications? A: Yes. Both parts are identical in resistance value (464 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. Mechanical dimensions and termination count are equivalent.

Q: Are there differences in the anti-sulfur coating between these parts? A: The ERJ-S1DF4640U specifies anti-sulfur coating as a feature. The RMCF2010FT464R does not list this feature in the provided specifications. This difference should be evaluated based on application requirements in sulfur-prone environments.

Q: Do both parts have the same moisture sensitivity rating? A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the package dimensions identical for PCB assembly? A: Yes. Both parts 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). Both are supplied in Tape & Reel format.

Q: What is the basis for substitution between these two parts? A: Substitution is based on matching resistance value, tolerance, power rating, package format, composition, temperature coefficient, operating temperature range, and automotive qualification (AEC-Q200). All these parameters are identical between the two parts.
