Key Parameters

Substitute Part Grouping Explanation

Substitutes are identified strictly by matching all key parameters, including nominal inductance, tolerance, current rating, DC resistance, shielding, mounting type, and physical dimensions. Only parts with identical or comparable values in these fields and compliance certifications are included. Packaging, case style, and RoHS/REACH status are maintained to ensure electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection for substitution should be based on the part status; the ASPI-0312FSSA-4R7M-T4 is obsolete. The substitute part, ASPI-0312FS-4R7M-T2, is active and matches key parameters, including electrical characteristics, package size, and compliance certifications such as RoHS3 and REACH. Only parameters explicitly provided should be considered in the equivalency decision.

Frequently Asked Questions (FAQ)

Q1: What is required to substitute ASPI-0312FSSA-4R7M-T4?
A1: Substitution must match inductance, tolerance, current rating, DC resistance, shielding, mounting type, package size, and compliance certifications as detailed above.

Q2: Are package dimensions identical between substitute and main part?
A2: Yes, both parts share a 3.00 mm x 3.00 mm footprint and a 1.20 mm maximum height.

Q3: Are compliance and certifications such as RoHS and REACH matched?
A3: Both the main part and substitute part are ROHS3 Compliant and REACH Unaffected.

Q4: Is the mounting method of the substitute the same as the original?
A4: Yes, both are designed for surface-mount applications.

Q5: Can the substitute part be used in the same PCB footprint?
A5: Both parts use a nonstandard 3.00 mm x 3.00 mm surface-mount package, providing mechanical compatibility for PCB integration based on dimensions provided.

Q6: Is the current rating of the substitute equivalent?
A6: The substitute has a current rating of 980 mA compared to 1 A for the original; matching within specified tolerance for application-critical design is determined strictly by provided specification.
