LCMGA201208T800RG Equivalent & Substitute Parts

Part Overview

The LCMGA201208T800RG is a power line ferrite bead manufactured by Taiyo Yuden, designed for electromagnetic interference (EMI) suppression in automotive applications. This 0805 (2012 Metric) surface mount component operates at 80 Ohms impedance at 100 MHz with a maximum current rating of 2.7A and is AEC-Q200 qualified for automotive use. The part is currently in active production status. Substitute parts are identified for applications requiring equivalent electrical and mechanical performance, particularly when the primary part is unavailable or when design requirements permit alternative manufacturers meeting identical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the LCMGA201208T800RG is determined by the following critical parameters:

Primary Substitution Criteria:

• Impedance @ Frequency: 80 Ohms @ 100 MHz
• Current Rating (Max): 2.7A or greater
• DC Resistance (DCR) (Max): 25mOhm or less
• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount
• Number of Lines: 1
• Filter Type: Power Line
• AEC-Q200 Qualification

Parts meeting all primary criteria are classified as parametric equivalents. Parts with variations in secondary parameters (such as impedance tolerance, operating temperature range, or manufacturer series designation) are evaluated for compatibility based on application requirements and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

FBMH2012HM800-TV (Taiyo Yuden): This part is a parametric equivalent to the LCMGA201208T800RG with identical electrical specifications and package dimensions. Both parts are manufactured by Taiyo Yuden and meet AEC-Q200 automotive qualification. However, FBMH2012HM800-TV carries a "Not For New Designs" product status designation, indicating it is in mature or declining production phase. Selection of this substitute is appropriate for legacy design support, replacement inventory, or applications where existing qualification data references this part number. For new design implementations, LCMGA201208T800RG is the preferred choice due to active production status.

782853680 (Würth Elektronik): This part differs from the LCMGA201208T800RG in three key aspects: impedance specification (68 Ohms versus 80 Ohms @ 100 MHz), filter type classification (Signal Line versus Power Line), and extended operating temperature range (-55°C to 125°C versus -40°C to 125°C). The current rating is higher at 3A. This part is AEC-Q200 qualified and ROHS3 compliant. The impedance deviation of 12 Ohms represents a 15% reduction from the specified 80 Ohm requirement. Selection of this substitute is limited to applications where the lower impedance value is acceptable and where signal line filtering characteristics are compatible with power line filtering requirements. The extended temperature range provides additional operational margin in extreme thermal environments.

Frequently Asked Questions (FAQ)

Q: Can FBMH2012HM800-TV be used as a direct replacement for LCMGA201208T800RG?

A: Yes, FBMH2012HM800-TV is a parametric equivalent with identical impedance (80 Ohms @ 100 MHz), current rating (2.7A), DC resistance (25mOhm), package (0805), and operating temperature range (-40°C to 125°C). Both parts are AEC-Q200 qualified. The primary consideration is that FBMH2012HM800-TV is designated "Not For New Designs," making it suitable for legacy applications or replacement scenarios rather than new product development.

Q: Is 782853680 compatible with LCMGA201208T800RG applications?

A: Compatibility depends on application-specific impedance requirements. The 782853680 operates at 68 Ohms @ 100 MHz, which is 12 Ohms lower than the specified 80 Ohms. Additionally, it is classified as a Signal Line filter rather than Power Line. These differences may affect EMI suppression performance in power distribution circuits. The higher current rating (3A) and extended temperature range (-55°C to 125°C) are advantageous in certain thermal environments. Substitution requires verification that the lower impedance and different filter type classification are acceptable for the specific application.

Q: Are all substitute parts in the same 0805 package?

A: Yes, all listed parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height specifications are within 0.002" (0.05mm) variation, ensuring compatibility with standard PCB assembly processes and reflow profiles.

Q: Do all parts meet automotive qualification standards?

A: Yes, LCMGA201208T800RG, FBMH2012HM800-TV, and 782853680 are all AEC-Q200 qualified, meeting automotive industry reliability and quality standards. All parts are ROHS3 compliant and carry REACH Unaffected status.

Q: What is the significance of "Power Line" versus "Signal Line" filter type classification?

A: Filter type indicates the intended application domain. Power Line ferrite beads are optimized for EMI suppression in power distribution circuits and high-current paths. Signal Line ferrite beads are designed for signal integrity protection in lower-current signal paths. While both types use similar ferrite core technology, their impedance characteristics and current handling are tailored to their respective applications. Substituting a Signal Line part (782853680) into a Power Line application (LCMGA201208T800RG) may result in suboptimal EMI suppression performance.

Q: What inventory considerations apply to these parts?

A: LCMGA201208T800RG has 899 pieces in stock, FBMH2012HM800-TV has 4,992 pieces, and 782853680 has 15,424 pieces available. Availability may influence substitution decisions when immediate procurement is required, though inventory levels are subject to change.
