Substitute Part Grouping Explanation

Substitution eligibility for the MLP2012V1R0TT is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 1 µH (±20% tolerance)
• Package / Case: 0805 (2012 Metric) surface mount
• Shielding type: Shielded
• Operating temperature range: -40°C ~ 125°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Criteria:

• Current Rating: Must equal or exceed 700 mA
• DC Resistance (DCR): Must not exceed 338 mOhm Max
• Moisture Sensitivity Level (MSL): 1 (Unlimited) or equivalent

The MLP2012S1R0T qualifies as a direct substitute because it maintains identical inductance, package, shielding, temperature range, and RoHS compliance while providing improved electrical performance through higher current rating (800 mA) and lower DC resistance (299 mOhm Max).

Engineering Selection Recommendations

The MLP2012S1R0T is the qualified substitute for the MLP2012V1R0TT based on the following engineering criteria:

Compliance & Status: The substitute part maintains full ROHS3 compliance and carries Active product status, ensuring long-term availability and manufacturing support compared to the obsolete main part.

Electrical Performance: The substitute delivers superior electrical characteristics with 100 mA additional current headroom (800 mA vs. 700 mA) and 39 mOhm lower DC resistance (299 mOhm vs. 338 mOhm). These improvements provide enhanced thermal performance and reduced power dissipation in the application circuit.

Physical & Thermal Compatibility: Identical package dimensions, height profile, and operating temperature range ensure direct PCB layout compatibility and thermal management equivalence.

Functional Equivalence: Both parts are shielded multilayer inductors with matching 1 µH inductance and ±20% tolerance, confirming functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can MLP2012S1R0T replace MLP2012V1R0TT in existing designs?

A: Yes. The substitute part maintains identical inductance value, package footprint, shielding configuration, and operating temperature range. The improved current rating and lower DC resistance provide enhanced performance margins.

Q: Are there any PCB layout modifications required when switching to MLP2012S1R0T?

A: No. Both parts use the 0805 (2012 Metric) surface mount package with identical dimensions (0.079" L x 0.049" W) and maximum seated height (0.022"). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the "Not For New Designs" status on MLP2012V1R0TT?

A: This designation indicates the part has been superseded in TDK's active product line. The MLP2012S1R0T represents the current generation equivalent, ensuring access to ongoing manufacturing support and supply chain continuity.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both the MLP2012V1R0TT and MLP2012S1R0T are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: How do the DC resistance specifications affect circuit performance?

A: The MLP2012S1R0T's lower maximum DC resistance (299 mOhm vs. 338 mOhm) reduces resistive losses and heat generation at rated current levels, improving overall circuit efficiency and thermal stability.
