Substitute Part Grouping Explanation

Substitution of the IM02EB2R2K is determined by strict equivalence across the following critical parameters:

• Inductance value: 2.2 µH with ±10% tolerance
• Current rating: minimum 395 mA
• DC resistance: 400mOhm maximum
• Q factor: 30 @ 7.9MHz
• Self-resonant frequency: 115MHz
• Operating temperature range: -55°C ~ 105°C
• Mounting configuration: Through-hole axial
• Physical dimensions: 0.095" Dia x 0.250" L
• Core material: Iron
• Shielding: Unshielded

The 1025R-28K from API Delevan Inc. meets all specified parameters with equivalent electrical performance and identical physical form factor, making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The 1025R-28K is suitable for direct substitution in applications currently using the IM02EB2R2K. The substitute part maintains identical electrical specifications and physical dimensions while offering improved current rating margin (415 mA versus 395 mA). Both components are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements. The active product status of the 1025R-28K provides superior long-term availability and supply chain continuity compared to the obsolete IM02EB2R2K.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-28K replace the IM02EB2R2K in existing designs?

A: Yes. Both components share identical inductance values, DC resistance, Q factor, self-resonant frequency, operating temperature range, and physical dimensions. The substitute part meets or exceeds all electrical specifications of the original component.

Q: What is the difference in current rating between these parts?

A: The IM02EB2R2K is rated for 395 mA maximum current, while the 1025R-28K is rated for 415 mA. The substitute provides a 20 mA higher current capacity, representing improved thermal margin in the same physical package.

Q: Are there packaging differences between these inductors?

A: No. Both components use identical through-hole axial packaging with 0.095" diameter and 0.250" length dimensions. PCB layout and mounting procedures remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the IM02EB2R2K and 1025R-28K are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: Why is the original part listed as obsolete?

A: The IM02EB2R2K is classified as obsolete by Vishay Dale. The 1025R-28K from API Delevan Inc. maintains active product status, ensuring continued availability and manufacturing support.
