Engineering Selection Recommendations

The 1025R-36K from API Delevan Inc. is the qualified substitute for the obsolete IM02EB4R7K. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part maintains identical electrical specifications and physical form factor, with a marginally higher current rating of 239 mA compared to the original 230 mA specification. The active product status of the 1025R-36K ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-36K be used as a direct replacement for the IM02EB4R7K?

A: Yes. Both components share identical inductance (4.7 µH), tolerance (±10%), DC resistance (1.2 Ohm max), core material (iron), shielding (unshielded), mounting type (through hole), package configuration (axial), operating temperature range (-55°C to 105°C), and physical dimensions (0.095" Dia x 0.250" L). The substitute part has a higher current rating (239 mA vs. 230 mA), which provides additional margin.

Q: Are there any physical compatibility concerns?

A: No. Both parts use identical axial through-hole packaging with matching dimensions of 0.095" diameter by 0.250" length. PCB footprints and mounting requirements are identical.

Q: What is the significance of the product status difference?

A: The IM02EB4R7K is classified as obsolete, meaning it is no longer manufactured or supported by Vishay Dale. The 1025R-36K maintains active product status, ensuring continued availability, technical support, and supply chain reliability.

Q: Do both parts meet current compliance standards?

A: Yes. Both the IM02EB4R7K and 1025R-36K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Are there differences in electrical performance?

A: No material differences exist. Both components exhibit identical Q factor (45 @ 7.9MHz), self-resonant frequency (75MHz), and inductance frequency test conditions (7.9 MHz).
