MMZ2012R150ATD25 Equivalent & Substitute Parts

Part Overview

The MMZ2012R150ATD25 is a signal line ferrite bead manufactured by TDK Corporation in the 0805 (2012 Metric) package. This component provides 15 Ohms of impedance at 100 MHz with a maximum current rating of 1.5A and 50mOhm DC resistance. The part carries Last Time Buy status, indicating it is being phased out. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring this ferrite bead specification.

Substitute Part Grouping Explanation

Substitution of the MMZ2012R150ATD25 is determined by the following critical electrical and mechanical parameters:

• Impedance specification: 15 Ohms @ 100 MHz (electrical requirement)
• Current rating: 1.5A maximum (electrical requirement)
• DC resistance: 50mOhm maximum (electrical requirement)
• Filter type: Signal Line, single line configuration (functional requirement)
• Series compatibility: MMZ series (manufacturer consistency)
• Operating temperature range: -55°C ~ 125°C (environmental requirement)
• Compliance certifications: AEC-Q200, ROHS3, REACH Unaffected (regulatory requirement)

The MMZ1608R150ATD25 meets all electrical specifications and compliance requirements. The primary difference is the package size: 0603 (1608 Metric) versus 0805 (2012 Metric). This substitution is valid when PCB layout permits the smaller footprint.

Parameter Comparison

Engineering Selection Recommendations

The MMZ1608R150ATD25 is an active product with identical electrical specifications to the MMZ2012R150ATD25. Both parts maintain AEC-Q200 qualification, ROHS3 compliance, and REACH unaffected status. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain stability.

Selection between these parts depends on PCB layout constraints. The 0603 (1608 Metric) package of the substitute is 20% smaller in length and 35% smaller in width compared to the 0805 (2012 Metric) main part. Height is reduced by approximately 8%. If board space permits the smaller footprint, the MMZ1608R150ATD25 is the preferred choice due to its active status. If the original 0805 package is required for mechanical or layout reasons, the MMZ2012R150ATD25 remains available as Last Time Buy inventory.

Frequently Asked Questions (FAQ)

Q: Can the MMZ1608R150ATD25 directly replace the MMZ2012R150ATD25 in my design?

A: Yes, from an electrical standpoint. Both parts deliver identical impedance (15 Ohms @ 100 MHz), current rating (1.5A), and DC resistance (50mOhm). The primary consideration is package size. The substitute uses a smaller 0603 (1608 Metric) footprint versus the original 0805 (2012 Metric). PCB layout must accommodate this smaller package.

Q: What is the difference between 0805 and 0603 packages?

A: These are metric package designations. 0805 (2012 Metric) measures 2.00mm length × 1.25mm width. 0603 (1608 Metric) measures 1.60mm length × 0.80mm width. The 0603 is more compact and suitable for space-constrained applications.

Q: Why is the main part marked Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. Existing inventory is available, but no future production is planned. The MMZ1608R150ATD25 substitute is an active product with continued manufacturing support.

Q: Are both parts qualified to the same standards?

A: Yes. Both the MMZ2012R150ATD25 and MMZ1608R150ATD25 carry AEC-Q200 qualification, ROHS3 compliance, and REACH unaffected status. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Can I use the larger 0805 package as a substitute if I only have access to the 0603?

A: No. The substitution logic is based on matching electrical specifications and compliance requirements. The 0603 (1608 Metric) substitute is smaller and suitable for designs originally specified for 0805 (2012 Metric). Reverse substitution with a larger package introduces unnecessary board space consumption and is not recommended.
