Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLF1005AR68K is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 680 nH
• Tolerance: ±10%
• Package / Case: 0402 (1005 Metric)
• Shielding type: Shielded
• Material - Core: Ferrite
• Operating Temperature range: -40°C ~ 85°C minimum
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating: May exceed the original 10 mA specification
• DC Resistance (DCR): May be lower than the original 800mOhm maximum
• Q @ Freq: May vary from the original 25 @ 10MHz
• Frequency - Self Resonant: Consistent at 150MHz
• Mounting Type: Surface Mount (consistent)

The MLF1005GR68KT000 qualifies as a direct substitute based on matching all mandatory parameters while providing improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MLF1005GR68KT000 is the qualified substitute for the obsolete MLF1005AR68K. Both components are manufactured by TDK Corporation within the MLF series and maintain identical inductance, tolerance, package dimensions, and thermal operating range specifications.

The substitute part demonstrates improved electrical performance with a higher current rating (45 mA versus 10 mA) and lower DC resistance (550mOhm maximum versus 800mOhm maximum), resulting in enhanced Q factor (30 @ 10MHz versus 25 @ 10MHz). These improvements ensure the substitute part operates within the design envelope of the original specification while providing additional performance margin.

Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating. The substitute part is currently in active production status with established supply chain availability, whereas the original part is obsolete. Packaging is available in Tape & Reel (TR) format for the substitute.

Frequently Asked Questions (FAQ)

Q: Can MLF1005GR68KT000 be used as a direct replacement for MLF1005AR68K in existing designs?

A: Yes. Both parts share identical inductance (680 nH), tolerance (±10%), package dimensions (0402 / 1005 Metric), shielding configuration, and operating temperature range (-40°C to 85°C). The substitute part meets or exceeds all electrical specifications of the original part.

Q: What are the differences between these two parts?

A: The primary differences are current rating (45 mA versus 10 mA), DC resistance (550mOhm maximum versus 800mOhm maximum), and Q factor (30 @ 10MHz versus 25 @ 10MHz). The substitute part provides superior electrical performance. Product status differs, with the original being obsolete and the substitute being active.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0402 (1005 Metric) package with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts.

Q: What packaging options are available for the substitute part?

A: The MLF1005GR68KT000 is available in Tape & Reel (TR) packaging format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They meet identical environmental and regulatory requirements.

Q: Why is the original part listed as obsolete?

A: The MLF1005AR68K is classified as obsolete, indicating it is no longer in active production. The MLF1005GR68KT000 represents the current active equivalent within the TDK MLF inductor series.
