LMMGA201208T800RG Equivalent & Substitute Parts

Part Overview

The LMMGA201208T800RG is a power line ferrite bead manufactured by Taiyo Yuden, designed for electromagnetic interference (EMI) suppression in electronic circuits. This 0805 (2012 Metric) surface mount component operates at 80 Ohms impedance at 100 MHz with a maximum current rating of 2.7A and DC resistance of 25mOhm. The part is currently in active production status. Substitute parts are necessary when the primary part experiences supply constraints, when design revisions require alternative manufacturers, or when inventory availability fluctuates across distribution channels.

Engineering Selection Recommendations

For new designs, select LMMGA201208T800RG or LSMGA201208T800RG, both of which carry Active product status and ensure long-term availability and manufacturer support. Both parts are manufactured by Taiyo Yuden and meet ROHS3 compliance requirements.

FBMH2012HM800-T is marked as Not For New Designs and should be used only in legacy design maintenance or when existing inventory must be consumed in production runs. This part remains available in higher quantities (4200 Pcs) but carries product lifecycle restrictions.

Z0805C800BPWZT, manufactured by KEMET, is classified as Obsolete and should not be selected for new applications. This part is available only through existing inventory channels and carries no manufacturer support or future availability guarantees.

All four parts are ROHS3 compliant with MSL 1 rating, indicating compatibility with standard surface mount assembly processes and unlimited shelf life under controlled storage conditions.

Frequently Asked Questions (FAQ)

Q: Can LSMGA201208T800RG be used as a direct replacement for LMMGA201208T800RG?

A: Yes. Both parts share identical electrical parameters (80 Ohms @ 100 MHz, 2.7A current rating, 25mOhm DCR), the same 0805 (2012 Metric) package, and equivalent operating temperature range. Both are Active status products from Taiyo Yuden. The primary difference is the internal series designation (LSMG vs. LMMG), which does not affect functional performance in power line ferrite bead applications.

Q: Why is FBMH2012HM800-T marked as Not For New Designs?

A: FBMH2012HM800-T carries a Not For New Designs status, indicating that Taiyo Yuden has transitioned this product line to newer alternatives. While the part meets all electrical and mechanical specifications, it should be used only for sustaining production of existing designs or inventory consumption. New designs should specify LMMGA201208T800RG or LSMGA201208T800RG.

Q: Is Z0805C800BPWZT suitable for production use?

A: Z0805C800BPWZT is classified as Obsolete and is not suitable for new production designs. This KEMET part should be used only when existing inventory must be depleted. No future availability or manufacturer support is guaranteed for obsolete components.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape packaging is supplied in smaller quantities on tape segments, typically used for manual assembly or lower-volume production. LMMGA201208T800RG, FBMH2012HM800-T, and LSMGA201208T800RG are supplied in Tape & Reel format. Z0805C800BPWZT is supplied in Cut Tape format, which may require manual handling or reel conversion for automated assembly lines.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts listed—LMMGA201208T800RG, FBMH2012HM800-T, LSMGA201208T800RG, and Z0805C800BPWZT—are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes and storage conditions.
