Parameter Comparison

Engineering Selection Recommendations

The 1537R-20K from API Delevan Inc. is a direct functional equivalent to the IM04EB2R2K. Both components maintain identical inductance values, DC resistance specifications, Q factors, and self-resonant frequencies. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability. Both parts maintain full ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The 1537R-20K provides a 50 mA higher current rating (485 mA versus 435 mA), which represents an operational margin improvement without introducing any electrical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1537R-20K be used as a direct replacement for the IM04EB2R2K in existing designs?

A: Yes. Both components share identical inductance (2.2 µH), DC resistance (950mOhm Max), Q factor (33 @ 7.9MHz), self-resonant frequency (135MHz), operating temperature range (-55°C ~ 125°C), and physical dimensions (0.156" Dia x 0.375" L). The axial through-hole mounting configuration is identical, allowing direct PCB substitution.

Q: What is the significance of the higher current rating on the 1537R-20K?

A: The 1537R-20K supports 485 mA compared to the IM04EB2R2K's 435 mA. This 50 mA increase provides additional operational margin and does not introduce any incompatibility. Designs operating within the original 435 mA specification will function identically with the substitute part.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the IM04EB2R2K and 1537R-20K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Why is product status relevant for this substitution?

A: The IM04EB2R2K is classified as obsolete, which may result in limited availability and potential supply discontinuation. The 1537R-20K maintains active product status, ensuring reliable long-term sourcing and continued manufacturer support.

Q: Are the physical dimensions and packaging identical?

A: Yes. Both components are packaged in axial configuration with identical dimensions of 0.156" Dia x 0.375" L (3.96mm x 9.53mm), ensuring mechanical compatibility with existing PCB layouts and through-hole mounting patterns.
