Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLFR1608T2R2M-LR is determined by the following critical parameters:

• Inductance Value: 2.2 µH with ±20% tolerance
• Package Compatibility: 0603 (1608 Metric) surface mount form factor
• Shielding Type: Shielded construction
• Current Handling: Minimum 500 mA continuous rating (original part rated 600 mA)
• DC Resistance: Maximum 250mOhm (original part 170mOhm)
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The MLZ1608A2R2WT000 meets these substitution criteria as an active, currently available alternative from the same manufacturer with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MLZ1608A2R2WT000 is the designated substitute for the obsolete GLFR1608T2R2M-LR. Both components are manufactured by TDK Corporation and maintain identical inductance values, package dimensions, and compliance certifications. The substitute part is currently in active production with 45,400 units in stock, ensuring supply chain continuity.

Design considerations for substitution:

• The MLZ1608A2R2WT000 operates at a reduced continuous current rating of 500 mA compared to the original 600 mA specification. Circuit designs must confirm that operating current does not exceed 500 mA.
• DC resistance increases from 170mOhm to 250mOhm, resulting in higher power dissipation. Thermal analysis should be performed for current-critical applications.
• The substitute part features an extended operating temperature range (-55°C to 125°C) compared to the original (-40°C to 105°C), providing broader environmental compatibility.
• Both parts maintain identical package footprints and MSL 1 moisture sensitivity ratings, allowing direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MLZ1608A2R2WT000 be used as a direct replacement for the GLFR1608T2R2M-LR?

A: Yes, the MLZ1608A2R2WT000 is electrically and mechanically compatible for applications where the circuit current does not exceed 500 mA. The identical inductance value, package dimensions, and shielding type ensure functional equivalence. However, the increased DC resistance must be evaluated for thermal performance in the specific application.

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

A: The primary differences are: (1) current rating reduced from 600 mA to 500 mA, (2) DC resistance increased from 170mOhm to 250mOhm, (3) saturation current reduced from 160mA to 130mA, and (4) operating temperature range expanded from -40°C to 105°C to -55°C to 125°C. The substitute part is multilayer ferrite construction versus the original design.

Q: Are there any PCB layout considerations when switching to the MLZ1608A2R2WT000?

A: No layout changes are required. Both parts use the 0603 (1608 Metric) package with identical footprint dimensions. The substitute part is 0.037" (0.95mm) in seated height compared to 0.039" (1.00mm) for the original, a negligible difference that does not affect assembly or clearance.

Q: What compliance certifications apply to the substitute part?

A: The MLZ1608A2R2WT000 is ROHS3 compliant, REACH unaffected, and carries MSL 1 (Unlimited) moisture sensitivity rating. These certifications match the original part's compliance profile.

Q: Is the MLZ1608A2R2WT000 available in the same packaging format?

A: Yes. The substitute part is supplied in Cut Tape (CT) and Digi-Reel® packaging, with 45,400 units currently in stock from TDK Corporation.
