Equivalent & Substitute Parts Reference: 1210-102K
Part Overview
Manufacturer part number 1210-102K is a fixed, unshielded SMD inductor from Delevan featuring 1 µH inductance, a maximum current rating of 515 mA, and 700 mOhm maximum DC resistance in the 1210 (3225 metric) package. The part is active and available, but due to requirements such as inventory constraints, compliance specifications, or procurement policy, it is necessary to identify equivalent or substitute models with specified electrical and mechanical compatibility.

Substitute Part Grouping Explanation
Substitute parts are selected strictly based on matching or closely aligned key parameters: inductance value (1 µH), maximum current rating, DC resistance (DCR), tolerance, shielding, core material, package type, physical dimension, and compliance or product status. Substitution is only valid where these values coincide with the requirements for electrical and mechanical compatibility, as explicitly stated in the input data.

Engineering Selection Recommendations
Selection between the main part 1210-102K and substitutes is determined by product status (all are active), regulatory compliance (RoHS/REACH), and moisture sensitivity (MSL). 1210-102K and 1210-102J are RoHS non-compliant, while CM322522-1R0JL is ROHS3 compliant. REACH status is unaffected for all options. Moisture Sensitivity Level is 1 (Unlimited) for all listed parts.
Frequently Asked Questions (FAQ)
Q1: Which electrical parameters are critical for substitution among 1210-102K, 1210-102J, and CM322522-1R0JL?
A1: Inductance value, DC resistance (DCR), current rating, tolerance, shielding type, Q at test frequency, and operating temperature define substitution eligibility.
Q2: Are there any significant package differences affecting compatibility?
A2: Both 1210-102K and 1210-102J use the 1210 (3225 Metric) package with identical dimensions, while CM322522-1R0JL is Nonstandard but has similar physical size.
Q3: How do RoHS and REACH compliance impact engineering selection?
A3: Selection depends on project compliance requirements. 1210-102K and 1210-102J are RoHS non-compliant; CM322522-1R0JL is ROHS3 compliant. All are REACH unaffected.
Q4: Is current rating a limiting factor for all substitutes?
A4: 1210-102K and 1210-102J have a current rating of 515 mA. CM322522-1R0JL supports 230 mA, which is lower.
Q5: What moisture sensitivity ratings apply to these SMD inductors?
A5: All listed components have Moisture Sensitivity Level (MSL) of 1 (Unlimited).
