LMMGA201208T221RG Equivalent & Substitute Parts

Part Overview

The LMMGA201208T221RG is a 220 Ohm power line ferrite bead manufactured by Taiyo Yuden in 0805 (2012 Metric) surface mount package. This component operates at 100 MHz impedance with a maximum current rating of 2A and 60mOhm DC resistance. The part is currently active in production. Substitute parts are necessary when the primary part experiences supply constraints, when alternative packaging formats are required, or when design revisions call for components from different manufacturers with equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMMGA201208T221RG is determined by the following critical parameters:

• Impedance @ 100 MHz: 220 Ohms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Current Rating (Max): 2A minimum
• DC Resistance (Max): 60mOhm maximum
• Operating Temperature Range: -40°C ~ 125°C minimum
• Filter Type: Power Line
• Number of Lines: 1
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Parts meeting these criteria are classified as parametric equivalents and may be used interchangeably in circuit designs. Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical compatibility but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

LSMGA201208T221RG (Taiyo Yuden) is the primary substitute, offering identical electrical specifications and operating temperature range with active product status. Both LMMGA201208T221RG and LSMGA201208T221RG are manufactured by Taiyo Yuden and provide equivalent performance for power line filtering applications.

MI0805M221R-10 (Laird-Signal Integrity Products) is an active alternative with identical impedance and current rating. This part features 50mOhm DC resistance, which is lower than the 60mOhm maximum specification, providing improved thermal performance. The part is ROHS3 compliant and REACH unaffected.

Conditional Substitutes:

FBMH2012HM221-T (Taiyo Yuden) meets all electrical and mechanical requirements but carries "Not For New Designs" status. This part is suitable only for legacy system maintenance or existing design revisions where supply of the primary part is unavailable.

Z0805C221BPWZT (KEMET) is obsolete and should not be selected for new designs or production applications.

Non-Equivalent Alternative:

CTCB0805F-201P (Central Technologies) has impedance of 200 Ohms at 100 MHz, which deviates from the 220 Ohm specification. Although it offers higher current rating (2.5A) and lower DC resistance (50mOhm), the impedance difference makes it unsuitable as a direct substitute for power line filtering where the 220 Ohm specification is critical to circuit performance.

Frequently Asked Questions (FAQ)

Q: Can CTCB0805F-201P be used as a substitute for LMMGA201208T221RG?

A: No. CTCB0805F-201P has 200 Ohm impedance at 100 MHz, while LMMGA201208T221RG requires 220 Ohms. The 20 Ohm difference affects filtering performance and circuit behavior. Although CTCB0805F-201P shares the same 0805 package and operating temperature range, the impedance mismatch disqualifies it as a parametric equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on tape segments, typically used for lower-volume orders or manual assembly. Both formats contain identical components; packaging selection depends on procurement volume and assembly equipment compatibility.

Q: Is FBMH2012HM221-T suitable for new product designs?

A: No. FBMH2012HM221-T carries "Not For New Designs" status and should be used only for maintenance of existing products or legacy system support. For new designs, select LSMGA201208T221RG or MI0805M221R-10, both of which are active products.

Q: What is the significance of DC Resistance (DCR) differences between substitutes?

A: DC Resistance affects power dissipation and thermal performance. MI0805M221R-10 has 50mOhm DCR compared to 60mOhm for LMMGA201208T221RG. Lower DCR reduces heat generation, which may be beneficial in thermally constrained applications. Both values meet the maximum specification of 60mOhm, making them electrically compatible.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitutes except CTCB0805F-201P (MSL undefined) are ROHS3 compliant. ROHS3 compliance ensures the parts meet European Union restrictions on hazardous substances and are suitable for applications requiring environmental compliance certification.
