Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLF1608T2R2M is determined by strict equivalence across the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±20% tolerance
• Package Specification: Must be 0603 (1608 Metric) surface mount
• Shielding Configuration: Must be shielded to maintain electromagnetic isolation
• Core Material: Ferrite construction required
• Physical Dimensions: Must fit within 0.063" L x 0.031" W footprint with maximum seated height of 0.039"

The MLZ1608A2R2WT000 qualifies as a direct substitute based on matching inductance value, package type, shielding, core material, and physical dimensions. While the substitute exhibits improved electrical performance characteristics (higher current rating, lower DCR, higher saturation current), these enhancements maintain backward compatibility with the original design requirements.

Engineering Selection Recommendations

The MLZ1608A2R2WT000 is the qualified substitute for the obsolete GLF1608T2R2M. Selection is based on the following engineering criteria:

Product Status: The MLZ1608A2R2WT000 maintains active production status with 45,400 pieces in current inventory, ensuring long-term availability compared to the obsolete GLF1608T2R2M.

Compliance and Certifications: The MLZ1608A2R2WT000 is ROHS3 compliant, providing enhanced environmental compliance over the original part. Both components maintain REACH Unaffected status and identical MSL ratings.

Electrical Performance: The substitute part delivers superior electrical characteristics with 500 mA current rating versus 275 mA, 250mOhm DCR versus 330mOhm, and 130mA saturation current versus 75mA. These improvements provide design margin without compromising backward compatibility.

Physical Compatibility: Both components share identical package specifications (0603/1608 Metric), footprint dimensions (0.063" x 0.031"), and mounting type. The substitute exhibits a marginal height reduction (0.037" versus 0.039"), which presents no assembly or clearance concerns.

Temperature Range: The MLZ1608A2R2WT000 extends the operating temperature range to -55°C to 125°C, providing broader environmental coverage than the original -40°C to 105°C specification.

Frequently Asked Questions (FAQ)

Q: Can the MLZ1608A2R2WT000 be used as a direct replacement for the GLF1608T2R2M?

A: Yes. Both components share identical inductance values (2.2 µH), tolerance specifications (±20%), package types (0603/1608 Metric), shielding configurations, and ferrite core materials. Physical dimensions and mounting types are equivalent, enabling direct PCB-level substitution.

Q: What are the key differences between these two inductors?

A: The primary differences are construction type (drum core wirewound versus multilayer), current ratings (275 mA versus 500 mA), DC resistance (330mOhm versus 250mOhm), and product status (obsolete versus active). The MLZ1608A2R2WT000 also provides ROHS3 compliance and an extended operating temperature range.

Q: Will the improved electrical performance of the MLZ1608A2R2WT000 affect circuit operation?

A: No. The substitute part's higher current rating, lower DC resistance, and higher saturation current represent performance enhancements that maintain full backward compatibility. Circuits designed for the GLF1608T2R2M specifications will operate within the MLZ1608A2R2WT000 operating envelope.

Q: Are there any height or footprint concerns when substituting these parts?

A: No. Both components use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W). The MLZ1608A2R2WT000 has a slightly lower seated height (0.037" versus 0.039"), which presents no assembly or clearance issues.

Q: What is the availability status of each part?

A: The GLF1608T2R2M is obsolete with 878 pieces in current inventory. The MLZ1608A2R2WT000 is in active production with 45,400 pieces available, ensuring reliable long-term supply for new designs and production continuity.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both components carry MSL rating 1 (Unlimited), indicating identical moisture handling and storage requirements.
