MLZ2012DR22MT000 Equivalent & Substitute Parts

Part Overview

The MLZ2012DR22MT000 is a 220 nH shielded multilayer inductor manufactured by TDK Corporation, rated for 900 mA continuous current with 130 mOhm DC resistance in a 0805 (2012 Metric) surface mount package. This component is classified as Not For New Designs, indicating it has been superseded in TDK's product portfolio. Finding equivalent or substitute parts is necessary for applications requiring continued supply, design refreshes, or alternative sourcing strategies.

Substitute Part Grouping Explanation

Substitute parts for the MLZ2012DR22MT000 are identified based on strict electrical and mechanical parameter matching:

Parametric Equivalents share identical or functionally equivalent specifications across all critical parameters: inductance value (220 nH), tolerance (±20%), DC resistance (130 mOhm), shielding type (Shielded), package format (0805/2012 Metric), and compliance certifications (ROHS3, MSL 1).

Current Rating Consideration: The main part specifies 900 mA continuous current with 800 mA saturation current. Substitute parts must maintain current ratings sufficient for the application. A reduction in current rating represents a functional limitation and requires application-level verification.

Operating Temperature Range: The main part operates from -55°C to 125°C. Substitutes with narrower temperature ranges may not be suitable for all applications.

Product Status: Active product status indicates ongoing manufacturer support and availability, whereas Not For New Designs status indicates end-of-life or transition phases.

Parameter Comparison

Engineering Selection Recommendations

MLZ2012DR22DT000 (TDK Corporation): This part is a direct parametric equivalent to the MLZ2012DR22MT000. It maintains identical electrical specifications (220 nH, 900 mA, 130 mOhm), mechanical dimensions, and operating temperature range (-55°C ~ 125°C). The primary distinction is Active product status, ensuring ongoing manufacturer support and supply availability. This part is the preferred substitute within the TDK MLZ series.

ASMCI-0805-R22M-T (Abracon LLC): This part provides electrical equivalence in inductance (220 nH), tolerance (±20%), and DC resistance (130 mOhm) with identical package format (0805/2012 Metric). However, it presents two functional limitations: reduced continuous current rating (800 mA versus 900 mA) and narrower operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C). Additionally, the seated height is 0.057" (1.45mm) compared to 0.041" (1.05mm) for the main part, which may affect PCB layout clearance. This part is suitable only for applications where the 800 mA current rating and -40°C ~ 85°C temperature range are acceptable.

Both substitute parts carry ROHS3 compliance and MSL 1 rating, matching the main part's environmental and regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can MLZ2012DR22DT000 be used as a direct replacement for MLZ2012DR22MT000?

A: Yes. The MLZ2012DR22DT000 is electrically and mechanically equivalent. Both parts specify 220 nH inductance, 900 mA current rating, 130 mOhm DC resistance, and identical 0805 (2012 Metric) package dimensions. The MLZ2012DR22DT000 has Active product status, providing supply continuity.

Q: What are the limitations of using ASMCI-0805-R22M-T as a substitute?

A: The ASMCI-0805-R22M-T has a reduced continuous current rating of 800 mA (versus 900 mA) and a narrower operating temperature range of -40°C ~ 85°C (versus -55°C ~ 125°C). The seated height is also 0.4mm taller. These differences must be evaluated against application requirements before selection.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), ensuring PCB footprint compatibility. Height differences should be verified for clearance-critical applications.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH Unaffected. Regulatory and environmental compliance is equivalent across all options.

Q: Which substitute should be selected for new designs?

A: The MLZ2012DR22DT000 is recommended for new designs, as it maintains full electrical and thermal specifications of the original part while offering Active product status and manufacturer support from TDK Corporation.
