Key Parameters

Substitute Part Grouping Explanation

Substitution of the 22M274J with the 2500-48J is based on electrical equivalence within the allowed parameter specifications for this inductor category. The substitute part maintains the same inductance value (2.7 mH), tolerance (±5%), DC resistance (33 Ohm Max), quality factor (70 @ 250 kHz), self-resonant frequency (1.8 MHz), operating temperature range (-55°C to 105°C), and mounting configuration (through-hole axial). The current rating of the substitute (65 mA) exceeds the main part specification (62 mA), providing additional design margin. Both components are unshielded molded inductors with identical electrical performance at the test frequency of 250 kHz. Physical dimensions differ slightly, but both maintain axial package geometry suitable for through-hole PCB assembly.

Parameter Comparison

Engineering Selection Recommendations

The 2500-48J from API Delevan Inc. is electrically equivalent to the 22M274J and suitable for direct substitution in applications where the electrical specifications are the primary selection criteria. The substitute part provides equal or superior performance across all critical electrical parameters. The 2500-48J has higher current rating capacity (65 mA versus 62 mA), which provides additional operational margin. Physical dimensions of the substitute are larger; PCB layout verification is necessary to confirm mechanical fit within the available board space. The 22M274J carries RoHS Not Applicable status, while the 2500-48J is RoHS non-compliant; compliance requirements of the end application must be evaluated. Both parts maintain REACH Unaffected status and EAR99 export classification. Inventory availability differs, with the 2500-48J having 1988 units in stock compared to 849 units for the 22M274J.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for the 2500-48J to substitute the 22M274J?

A: The inductance (2.7 mH), tolerance (±5%), DC resistance (33 Ohm Max), quality factor (70 @ 250 kHz), self-resonant frequency (1.8 MHz), and operating temperature range (-55°C to 105°C) must remain equivalent. The 2500-48J meets all these requirements.

Q: Does the larger physical size of the 2500-48J affect electrical performance?

A: Physical dimensions do not alter the electrical specifications. However, PCB layout must accommodate the larger axial package (0.240" Dia x 0.740" L versus 0.215" Dia x 0.560" L). Mechanical fit verification is required before implementation.

Q: Can the 2500-48J be used in applications requiring RoHS compliance?

A: The 2500-48J is RoHS non-compliant. If RoHS compliance is mandatory for the end application, the 22M274J (RoHS Not Applicable) may be the appropriate choice, or alternative RoHS-compliant inductors must be evaluated.

Q: Is the higher current rating of the 2500-48J (65 mA) a benefit?

A: The higher current rating (65 mA versus 62 mA) provides additional design margin and operational headroom. This is compatible with applications designed for the 22M274J.

Q: Are both parts suitable for the same frequency range?

A: Both parts are tested and specified at 250 kHz with identical self-resonant frequency (1.8 MHz). They are suitable for equivalent RF applications within these frequency parameters.
