Frequently Asked Questions (FAQ)

Q1: What are the main substitution criteria for the AISC-0402-23NJ-T?
A1: Substitution is determined using inductance, tolerance, current rating, DC resistance (DCR), shielding type, Q at specified frequency, self-resonant frequency, operating temperature, package/case, RoHS status, MSL, REACH status, and ECCN.

Q2: Are there physical dimension differences between AISC-0402-23NJ-T and 744765123A?
A2: Yes. Both parts use the 0402 (1005 Metric) package; however, slight differences exist in their listed dimensions.

Q3: Is the shielded or unshielded property considered in substitution?
A3: Yes, shielding type is a key parameter and only unshielded types are considered valid substitutes.

Q4: Are compliance and regulatory certifications matched between the substitutes?
A4: Both substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q5: Is tape and reel packaging a requirement for substitution?
A5: Both primary and substitute parts are supplied in types of tape and reel packaging as specified.
