Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GLFR1608T150M-LR is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH with ±20% tolerance
• Package / Case: 0603 (1608 Metric) form factor
• Operating temperature range: -40°C ~ 105°C minimum
• RoHS3 compliance status
• Surface mount mounting type

Secondary Compatibility Factors:

• Current rating capability (minimum 200 mA acceptable for 220 mA rated application)
• DC resistance characteristics (lower DCR values acceptable; higher values require circuit analysis)
• Saturation current performance

The BRL1608T150M from Taiyo Yuden meets the primary matching criteria with identical inductance, package, temperature range, and RoHS compliance. However, differences in shielding type, DCR specification, and saturation current performance require engineering evaluation for specific circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The BRL1608T150M qualifies as a functional equivalent based on matching inductance value, package form factor, temperature operating range, and RoHS3 compliance. Both components share identical inductance specifications and tolerance ratings, enabling direct substitution from an inductance perspective.

Key considerations for selection:

Shielding Difference: The GLFR1608T150M-LR features shielded construction while the BRL1608T150M is unshielded. Applications requiring electromagnetic interference (EMI) suppression or operating in magnetically sensitive environments must account for this architectural difference.

DC Resistance Variance: The substitute part exhibits significantly higher DC resistance (3.328Ohm Max versus 900mOhm). This impacts power dissipation and thermal performance in current-carrying applications. Circuit designs with tight power budget constraints require thermal analysis.

Current Rating: The BRL1608T150M is rated for 200 mA continuous current, which is 20 mA below the original part's 220 mA rating. Applications operating near the original current specification require margin analysis.

Product Status: Both components carry end-of-life designations (Obsolete and Not For New Designs), indicating limited future availability. Long-term production programs should evaluate alternative 15 µH inductors with active product status.

Frequently Asked Questions (FAQ)

Q: Can the BRL1608T150M directly replace the GLFR1608T150M-LR in all applications?

A: Direct substitution is possible from an inductance and package perspective. However, the unshielded construction and higher DC resistance require circuit-level evaluation. Applications sensitive to magnetic field coupling or operating at elevated current levels may require design modifications.

Q: What is the impact of the shielding difference?

A: Shielded inductors contain magnetic fields within the component structure, reducing coupling to adjacent circuit elements. Unshielded inductors exhibit greater magnetic field radiation. In densely populated PCB layouts or noise-sensitive circuits, this difference may affect performance.

Q: Why is the DC resistance specification so different?

A: The GLFR1608T150M-LR uses a shielded design with optimized winding for low resistance (900mOhm). The BRL1608T150M employs a drum core wirewound construction with higher resistance (3.328Ohm Max). This affects power dissipation: at 200 mA, the substitute dissipates approximately 1.33W compared to 0.036W for the original part.

Q: Are both parts RoHS compliant?

A: Yes, both the GLFR1608T150M-LR and BRL1608T150M carry ROHS3 compliance certification, meeting environmental and regulatory requirements for restricted substance use.

Q: What is the physical height difference significance?

A: The BRL1608T150M has a lower seated height (0.028" versus 0.039"), which may provide advantages in space-constrained designs. This difference does not affect electrical performance but may influence PCB layout and component clearance considerations.

Q: Should new designs use either of these parts?

A: Both components carry end-of-life product status. New design programs should evaluate alternative 15 µH inductors with active manufacturer support and production commitments to ensure long-term supply chain stability.
