Engineering Selection Recommendations

1025R-76K (API Delevan Inc.)

The 1025R-76K is an active product supplied in bulk packaging. This substitute maintains full electrical and mechanical equivalence to the IM02EB221K and carries ROHS3 compliance certification, matching the original part's regulatory status. The bulk packaging format suits applications requiring individual component handling or custom assembly processes.

ER1025-76KM (API Delevan Inc.)

The ER1025-76KM is an active product supplied in Tape & Reel (TR) format, optimized for automated assembly and high-volume production environments. This substitute delivers identical electrical performance and mechanical compatibility. Note that this part carries RoHS non-compliant status, which may impact suitability for applications subject to RoHS3 regulatory requirements.

ER1025-76KP (API Delevan Inc.)

The ER1025-76KP is an active product supplied in Tape & Reel (TR) format, designed for automated manufacturing processes. This substitute provides complete electrical and mechanical equivalence to the IM02EB221K. Like the ER1025-76KM, this part carries RoHS non-compliant status and should be evaluated against applicable regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-76K, ER1025-76KM, and ER1025-76KP be used interchangeably with the IM02EB221K?

A: Yes. All three substitute parts meet the complete set of electrical and mechanical parameters specified for the IM02EB221K, including inductance, current rating, DC resistance, frequency characteristics, temperature range, core material, shielding, mounting type, package style, and physical dimensions. Direct substitution is electrically and mechanically valid.

Q: What is the difference between the three substitute parts?

A: The primary differences are product status, packaging format, and regulatory compliance. The 1025R-76K is supplied in bulk packaging and maintains ROHS3 compliance. The ER1025-76KM and ER1025-76KP are both supplied in Tape & Reel format for automated assembly but carry RoHS non-compliant status. All three deliver identical electrical performance.

Q: Which substitute should I select for automated assembly?

A: Both ER1025-76KM and ER1025-76KP are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly processes. Selection between these two depends on regulatory compliance requirements and supplier availability.

Q: Which substitute should I select if RoHS3 compliance is required?

A: The 1025R-76K maintains ROHS3 compliance matching the original IM02EB221K specification. The ER1025-76KM and ER1025-76KP are RoHS non-compliant and should not be used in applications requiring RoHS3 certification.

Q: Are there any physical dimension differences between the substitute parts and the original?

A: No. All substitute parts maintain the identical axial package dimensions of 0.095" Dia x 0.250" L (2.41 mm x 6.35 mm), ensuring direct mechanical compatibility with existing PCB layouts and through-hole mounting positions.

Q: What is the inventory status of these substitute parts?

A: The 1025R-76K has 753 pieces in stock, ER1025-76KM has 773 pieces in stock, and ER1025-76KP has 887 pieces in stock, all listed as new original inventory.
