LMMGA201208T331RG Equivalent & Substitute Parts

Part Overview

The LMMGA201208T331RG is a 330 Ohm power line ferrite bead manufactured by Taiyo Yuden in 0805 (2012 Metric) surface mount package. This component is rated for 1.8A maximum current with 80mOhm DC resistance and operates across -40°C to 125°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources become necessary due to supply availability, lead time requirements, or design flexibility across manufacturing partners.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical specifications. The primary substitution criteria are:

Electrical Parameters:

• Impedance @ 100 MHz: 330 Ohms (exact match required)
• Current Rating: minimum 1.8A
• DC Resistance: maximum 80mOhm
• Operating Temperature: -40°C to 125°C minimum

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount
• Number of Lines: 1
• Filter Type: Power Line

Compliance Parameters:

• RoHS3 Compliant
• MSL rating compatible with application requirements

Parts meeting all electrical and mechanical criteria are classified as parametric equivalents. Parts with impedance values within acceptable tolerance (300-330 Ohms @ 100 MHz) and equal or superior current ratings are listed as functional alternatives where application design permits.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Status, Exact Electrical Match):

LSMGA201208T331RG (Taiyo Yuden) and CTCB0805F-331P (Central Technologies) are direct substitutes meeting all electrical and mechanical parameters with Active product status. Both maintain 330 Ohm impedance @ 100 MHz, 1.8A minimum current rating, and 80mOhm maximum DC resistance in 0805 package format. CTCB0805F-331P provides 2.0A current capability, offering design margin above the 1.8A requirement.

Alternative Substitutes (Functional Compatibility):

CTCB0805F-301P and CTCB0805F-301S (Central Technologies) and MI0805L301R-10 (Laird-Signal Integrity Products) operate at 300 Ohms @ 100 MHz with 2.0A current ratings. These parts are suitable where impedance tolerance of ±10% from 330 Ohms is acceptable within circuit design specifications. MI0805L301R-10 provides superior DC resistance performance at 60mOhm maximum.

Not Recommended for New Designs:

FBMH2012HM331-T (Taiyo Yuden) carries "Not For New Designs" status despite exact electrical equivalence. Z0805C331BPWZT (KEMET) is classified as Obsolete and should not be selected for new applications.

Frequently Asked Questions (FAQ)

Q: Can CTCB0805F-301P or CTCB0805F-301S replace LMMGA201208T331RG?

A: These parts are functionally compatible substitutes. Both maintain 0805 package format, 80mOhm DC resistance, and -40°C to 125°C operating range. The 300 Ohm impedance represents a 9% reduction from the 330 Ohm specification. Substitution is valid where circuit design permits impedance tolerance within ±10% of the original specification.

Q: What is the difference between LSMGA201208T331RG and LMMGA201208T331RG?

A: Both are Taiyo Yuden ferrite beads with identical electrical specifications: 330 Ohms @ 100 MHz, 1.8A current rating, 80mOhm DC resistance, and 0805 package. LSMGA201208T331RG belongs to the LSMG series while LMMGA201208T331RG belongs to the LMMG series. Both maintain Active product status and ROHS3 compliance. Selection between them depends on availability and supply chain requirements.

Q: Why is FBMH2012HM331-T marked "Not For New Designs"?

A: FBMH2012HM331-T carries legacy product status despite meeting all electrical and mechanical parameters. Taiyo Yuden designates this part for existing design support only. New designs should select LSMGA201208T331RG or LMMGA201208T331RG from the active product portfolio.

Q: Can MI0805L301R-10 be used as a substitute?

A: MI0805L301R-10 is a functional alternative with 300 Ohm impedance and 2.0A current rating. The primary advantage is superior DC resistance at 60mOhm maximum versus 80mOhm. Substitution is valid where impedance tolerance of ±10% is acceptable. The part is manufactured by Laird-Signal Integrity Products and maintains Active status with ROHS3 compliance.

Q: What packaging formats are available for these substitutes?

A: All listed substitutes are supplied in 0805 (2012 Metric) surface mount package. FBMH2012HM331-T, LSMGA201208T331RG, LMMGA201208T331RG, CTCB0805F series, and Z0805C331BPWZT are available in Tape & Reel (TR) format. MI0805L301R-10 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on production volume and assembly process requirements.

Q: Are all substitutes ROHS3 compliant?

A: All listed substitutes maintain ROHS3 compliance. Moisture sensitivity levels vary: Taiyo Yuden parts specify MSL 1 (Unlimited), Central Technologies parts list MSL as Vendor Undefined, Laird parts specify Not Applicable, and KEMET specifies MSL 1 (Unlimited). Verify MSL requirements against specific application storage and handling conditions.
