Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDCS5020ER150M is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH (within ±20% tolerance specification)
• Core type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration
• Mounting: Surface mount, nonstandard package
• Temperature range: -40°C to 125°C minimum

Current Performance Criteria:

• Current rating must meet or exceed 1.5 A continuous operation
• Saturation current (Isat) must support application requirements
• DC resistance must remain within acceptable limits for the application circuit

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required

The SRR1005-150M from Bourns Inc. qualifies as a direct substitute based on matching inductance value, ferrite core material, shielded drum core construction, surface mount configuration, identical temperature operating range, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SRR1005-150M qualifies as a direct substitute for the IDCS5020ER150M based on electrical parameter equivalence and regulatory compliance alignment. Both components maintain Active product status with full RoHS3 compliance and REACH unaffected designation.

The substitute part demonstrates performance advantages in current rating (1.7 A versus 1.5 A) and saturation current (2.1 A versus 2.0 A), providing additional operational margin. The lower DC resistance specification (85 mOhm maximum versus 150 mOhm maximum) reduces power dissipation in the inductor element.

Physical dimensions show minimal variation within typical PCB layout tolerances. The substitute maintains identical temperature operating range and moisture sensitivity classification, ensuring thermal and environmental compatibility.

Component selection between these parts should be based on availability, lead time requirements, and specific circuit performance objectives. Both parts satisfy the core electrical and mechanical requirements for 15 µH shielded drum core wirewound inductor applications in surface mount configurations.

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-150M directly replace the IDCS5020ER150M on existing PCBs?

A: Yes. Both inductors share identical inductance values (15 µH), matching tolerance specifications (±20%), and equivalent operating temperature ranges (-40°C to 125°C). Physical dimensions are within typical PCB layout tolerances. No circuit redesign is required.

Q: What is the significance of the lower DC resistance in the SRR1005-150M?

A: The SRR1005-150M specifies 85 mOhm maximum DC resistance compared to 150 mOhm maximum for the IDCS5020ER150M. Lower DC resistance reduces resistive losses and heat generation during operation, improving overall circuit efficiency. This represents a performance advantage when thermal management is a design consideration.

Q: Are both parts suitable for the same current applications?

A: The SRR1005-150M exceeds the current rating of the IDCS5020ER150M (1.7 A versus 1.5 A continuous rating). Applications designed for 1.5 A operation are fully compatible with the substitute part. The higher saturation current (2.1 A versus 2.0 A) provides additional operational headroom.

Q: Do both inductors meet the same regulatory requirements?

A: Yes. Both the IDCS5020ER150M and SRR1005-150M maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels are identical (MSL 1, Unlimited). No regulatory or compliance issues arise from substitution.

Q: What are the dimensional differences between these parts?

A: The IDCS5020ER150M measures 12.95mm length × 9.40mm width with 5.08mm maximum seated height. The SRR1005-150M measures 12.70mm length × 10.00mm width with 5.20mm maximum seated height. Variations are minimal and typically accommodated within standard PCB design margins.

Q: Which part should be selected for new designs?

A: Selection between these parts depends on availability, supplier lead times, and specific performance requirements. Both parts are Active status components with equivalent electrical performance. Consult current inventory and delivery schedules for procurement decisions.
