Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LBMGA201208T331RG are classified based on strict adherence to the following electrical and mechanical parameters:

Primary Equivalence Criteria:

• Impedance @ 100 MHz: 330 Ohms (exact match required)
• Package / Case: 0805 (2012 Metric)
• Filter Type: Power Line
• Number of Lines: 1
• Operating Temperature Range: -40°C ~ 125°C
• RoHS3 Compliance

Secondary Compatibility Parameters:

• Current Rating (Max): 1.8A or higher
• DC Resistance (Max): 80mOhm or lower
• Mounting Type: Surface Mount

Parts meeting all primary criteria are classified as direct parametric equivalents. Parts with impedance values within the 300-330 Ohm range at 100 MHz and identical package specifications are classified as functional alternatives when current rating and DCR specifications are maintained or improved.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for New Designs):

LSMGA201208T331RG (Taiyo Yuden) and CTCB0805F-331P (Central Technologies) provide exact electrical and mechanical equivalence to the LBMGA201208T331RG. Both parts maintain 330 Ohm impedance at 100 MHz, identical package specifications, and active product status. LSMGA201208T331RG is a Taiyo Yuden alternative within the same manufacturer family. CTCB0805F-331P offers equivalent performance from an alternative manufacturer with improved current rating (2A vs. 1.8A).

Functional Alternatives (300 Ohm Impedance):

CTCB0805F-301P, CTCB0805F-301S, and MI0805L301R-10 operate at 300 Ohms @ 100 MHz, representing a 9% reduction from the specified 330 Ohm impedance. These parts maintain identical package geometry and operating temperature range. Current ratings are equal to or exceed the original specification (2A vs. 1.8A). DC resistance values are equal to or lower than the original specification. These alternatives are suitable for applications where 300 Ohm impedance provides acceptable filtering performance.

Legacy Status:

FBMH2012HM331-T (Taiyo Yuden) and Z0805C331BPWZT (KEMET) maintain exact electrical equivalence but carry "Not For New Designs" and "Obsolete" status respectively. These parts should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can CTCB0805F-301P or CTCB0805F-301S be used as direct replacements for LBMGA201208T331RG?

A: These parts are functionally compatible alternatives. They maintain identical package specifications (0805 / 2012 Metric), operating temperature range (-40°C ~ 125°C), and DC resistance (80mOhm). The impedance difference is 300 Ohms versus 330 Ohms at 100 MHz. Current rating is improved (2A vs. 1.8A). Suitability depends on whether 300 Ohm impedance meets the filtering requirements of your specific application.

Q: What is the difference between LSMGA201208T331RG and LBMGA201208T331RG?

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 LBMGA201208T331RG belongs to the LBMG series. Both are active products suitable for new designs.

Q: Why is Z0805C331BPWZT listed if it is obsolete?

A: Z0805C331BPWZT is included for reference in legacy system documentation and reverse engineering applications. It provides exact electrical equivalence (330 Ohms @ 100 MHz, 1.8A, 80mOhm) but should not be selected for new product development due to obsolete status.

Q: Are there packaging differences between these substitute parts?

A: All listed substitutes use 0805 (2012 Metric) surface mount packaging. Minor dimensional variations exist: Taiyo Yuden parts (LBMGA, LSMGA, FBMH) and KEMET Z0805C specify 0.041" maximum height, while Central Technologies CTCB parts specify 0.043" maximum height. These variations remain within standard 0805 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute offers the best current handling capability?

A: CTCB0805F-301P, CTCB0805F-301S, CTCB0805F-331P, and MI0805L301R-10 all provide 2A maximum current rating, compared to 1.8A for the original LBMGA201208T331RG. For applications requiring maximum current capacity, these alternatives provide improved headroom.

Q: Is CTCB0805F-331P the best substitute for new designs?

A: CTCB0805F-331P is a strong candidate for new designs. It maintains exact impedance specification (330 Ohms @ 100 MHz), identical package geometry, and improves current rating to 2A. It carries active product status and ROHS3 compliance. LSMGA201208T331RG remains an alternative if Taiyo Yuden sourcing is preferred.
