Key Parameters

Substitute Part Grouping Explanation

The SDR1006-331KL from Bourns Inc. qualifies as a substitute for the IDCP3722ER331M based on the following critical parameters:

• Inductance value matches at 330 µH
• Current rating is equivalent at 520 mA
• DC resistance maximum is identical at 1.15Ohm
• Core material and type are identical (ferrite, drum core, unshielded)
• Mounting type is identical (surface mount)
• Both components are ROHS3 compliant
• Both are packaged in Tape & Reel format
• Inductance test frequency is identical at 1 kHz

The substitute part maintains all critical electrical parameters required for functional equivalence in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the IDCP3722ER331M and SDR1006-331KL are active production components with full ROHS3 compliance and REACH unaffected status. The SDR1006-331KL offers a tighter inductance tolerance of ±10% compared to the ±20% tolerance of the IDCP3722ER331M, while maintaining identical electrical performance at the specified current rating and DC resistance. The SDR1006-331KL supports an extended operating temperature range of -40°C to 125°C versus -25°C to 105°C for the IDCP3722ER331M. Physical dimensions are comparable with minor variations in length, width, and height that remain within typical PCB layout tolerances for nonstandard surface mount packages. Component selection should be based on application-specific requirements for temperature range, tolerance specifications, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that define substitution eligibility for the IDCP3722ER331M?

A: The critical parameters are inductance value (330 µH), current rating (520 mA), DC resistance maximum (1.15Ohm), core material and type (ferrite drum core unshielded), and mounting type (surface mount). All substitute parts must match these specifications exactly.

Q: How do the inductance tolerances differ between the main part and substitute?

A: The IDCP3722ER331M has an inductance tolerance of ±20%, while the SDR1006-331KL has a tighter tolerance of ±10%. Both tolerances are acceptable for substitution as they define the acceptable variation range around the 330 µH nominal value.

Q: Are there physical dimension differences that affect PCB compatibility?

A: The IDCP3722ER331M measures 10.00mm x 9.00mm with a maximum seated height of 5.40mm. The SDR1006-331KL measures 9.80mm x 9.80mm with a maximum seated height of 5.80mm. These minor dimensional variations are typical for nonstandard surface mount packages and should be verified against specific PCB layout requirements.

Q: What is the difference in operating temperature ranges?

A: The IDCP3722ER331M operates from -25°C to 105°C, while the SDR1006-331KL operates from -40°C to 125°C. The substitute part provides extended temperature capability, which is beneficial for applications requiring wider temperature performance.

Q: Are both parts compliant with environmental regulations?

A: Both the IDCP3722ER331M and SDR1006-331KL are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What packaging formats are available for these inductors?

A: Both components are supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly processes and high-volume production environments.
