Substitute Part Grouping Explanation

The 1025R-72K qualifies as a direct substitute for the 1025-72K based on identical electrical and mechanical parameters. Substitution compatibility is determined by the following matching criteria:

Matching Parameters:

• Inductance: 150 µH with ±10% tolerance
• Current Rating: 61 mA
• DC Resistance: 15Ω Max
• Q Factor: 30 @ 790kHz
• Self Resonant Frequency: 11 MHz
• Operating Temperature Range: -55°C to 105°C
• Core Material: Ferrite (unshielded)
• Mounting Type: Through Hole Axial
• Physical Dimensions: 0.095" Dia x 0.250" L

Both parts belong to API Delevan's molded inductor series and maintain identical specifications across all functional parameters. The 1025R-72K represents an updated variant within the same product family with enhanced material compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the 1025-72K and 1025R-72K are active products suitable for component selection. The primary differentiation lies in regulatory compliance status. The 1025-72K is RoHS non-compliant, while the 1025R-72K achieves ROHS3 compliance. For applications requiring RoHS3 certification or operating within regulated environments, the 1025R-72K is the appropriate selection. Both parts maintain identical electrical performance and physical characteristics. The 1025R-72K offers superior inventory availability with 1661 units in stock compared to 827 units for the 1025-72K, supporting expedited procurement timelines when required.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-72K replace the 1025-72K in existing designs? A: Yes. The 1025R-72K is a direct electrical and mechanical equivalent with identical inductance (150 µH), current rating (61 mA), DC resistance (15Ω Max), and all RF characteristics. Pin-to-pin compatibility and package dimensions are identical (0.095" Dia x 0.250" L axial through-hole).

Q: What is the difference between these two parts? A: The primary difference is RoHS compliance status. The 1025R-72K meets ROHS3 standards while the 1025-72K does not. All electrical specifications and mechanical dimensions are identical. Both use ferrite cores and operate across -55°C to 105°C.

Q: Are there any impedance or frequency response differences? A: No. Both parts deliver identical Q factor performance (30 @ 790kHz) and self-resonant frequency (11 MHz). Inductance tolerance specifications are identical at ±10%.

Q: Which part should I specify for a new design? A: For new designs requiring RoHS3 compliance, specify 1025R-72K. Both parts support active procurement through API Delevan Inc.

Q: Does PCB layout or board-level considerations differ between these inductors? A: No. Axial through-hole mounting and identical physical dimensions (0.095" Dia x 0.250" L) ensure identical PCB integration and thermal characteristics.

Q: What is the current rating specification, and is it identical for both parts? A: Both parts are rated for 61 mA continuous current with maximum DC resistance of 15Ω at that rating. Current saturation specifications were not provided for either part.
