LCMGA160808T151RG Ferrite Bead Equivalent & Substitute Parts

Part Overview

The LCMGA160808T151RG is a 150 Ohm power line ferrite bead manufactured by Taiyo Yuden in 0603 (1608 Metric) surface mount package. This component is designed for electromagnetic interference (EMI) suppression in automotive and general-purpose applications. The part is currently in active production status with AEC-Q200 automotive qualification.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements allow for alternative electrical characteristics within acceptable tolerances. The ferrite beads listed as substitutes provide equivalent or comparable filtering performance while maintaining compatibility with 0603 package footprints and automotive-grade reliability standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the LCMGA160808T151RG is based on the following critical parameters:

Exact Electrical Match (150 Ohm @ 100 MHz):

• FBMH1608HM151-TV (Taiyo Yuden) provides identical impedance, current rating, and DC resistance specifications. This part is functionally equivalent but carries a "Not For New Designs" status.

Comparable Electrical Performance (120 Ohm @ 100 MHz):

• ABUP00160808121Y00 (Pulse Electronics)
• BLM18KG121TH1D (Murata Electronics)
• BLM18KG121TZ1D (Murata Electronics)
• BLM18SG121TZ1D (Murata Electronics)

These parts operate at 120 Ohms impedance, representing an 80 Ohm reduction from the primary specification. However, they offer higher current ratings (3A versus 2.1A) and lower DC resistance (25–30 mOhm versus 50 mOhm). All substitute parts maintain the 0603 package footprint, single power line configuration, AEC-Q200 automotive qualification, and RoHS3 compliance.

Substitution Criteria:

• Package compatibility: 0603 (1608 Metric) surface mount
• Filter type: Power line
• Number of lines: 1
• Automotive qualification: AEC-Q200
• Environmental compliance: RoHS3, REACH Unaffected
• Moisture sensitivity: MSL 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

FBMH1608HM151-TV is the only substitute offering exact electrical equivalence to LCMGA160808T151RG. Both parts provide 150 Ohm impedance at 100 MHz, 2.1A current rating, and 50 mOhm DC resistance. However, FBMH1608HM151-TV carries a "Not For New Designs" product status, indicating Taiyo Yuden has transitioned this part to end-of-life. This part is suitable for legacy system maintenance and repair applications where the original specification must be preserved.

For New Designs with Electrical Tolerance:

ABUP00160808121Y00, BLM18KG121TH1D, BLM18KG121TZ1D, and BLM18SG121TZ1D are all active production parts with enhanced electrical performance characteristics. These parts operate at 120 Ohm impedance (20 Ohm reduction from primary specification) but provide superior current handling (3A versus 2.1A) and reduced DC resistance (25–30 mOhm versus 50 mOhm). All four parts maintain AEC-Q200 automotive qualification and RoHS3 compliance.

Product Status Considerations:

• LCMGA160808T151RG: Active production, recommended for new designs
• FBMH1608HM151-TV: Not for new designs; use only for legacy applications
• ABUP00160808121Y00, BLM18KG121TH1D, BLM18KG121TZ1D, BLM18SG121TZ1D: All active production

Compliance and Certification:

All listed parts carry AEC-Q200 automotive qualification, RoHS3 compliance, and REACH unaffected status. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can FBMH1608HM151-TV be used as a direct replacement for LCMGA160808T151RG?

A: Yes, FBMH1608HM151-TV provides identical electrical specifications (150 Ohm @ 100 MHz, 2.1A, 50 mOhm DCR) and is mechanically compatible in the 0603 package. However, this part is designated "Not For New Designs" and should be reserved for legacy system repairs. For new designs, use LCMGA160808T151RG or evaluate the active production alternatives.

Q: What is the impedance difference between the primary part and the Murata/Pulse alternatives?

A: LCMGA160808T151RG operates at 150 Ohm impedance at 100 MHz. The substitute parts (ABUP00160808121Y00, BLM18KG121TH1D, BLM18KG121TZ1D, BLM18SG121TZ1D) operate at 120 Ohm impedance, representing an 80 Ohm reduction. This difference affects EMI attenuation characteristics and must be evaluated against circuit requirements.

Q: Are all substitute parts compatible with the 0603 package footprint?

A: Yes, all listed substitute parts use the 0603 (1608 Metric) surface mount package. Physical dimensions are compatible with existing PCB layouts. Height variations range from 0.65 mm to 0.95 mm; verify clearance in applications with height constraints.

Q: Do the substitute parts maintain automotive qualification?

A: Yes, all substitute parts carry AEC-Q200 automotive qualification, matching the primary part's certification level. All parts are RoHS3 compliant and REACH unaffected.

Q: What is the current rating advantage of the substitute parts?

A: The substitute parts (ABUP00160808121Y00, BLM18KG121TH1D, BLM18KG121TZ1D, BLM18SG121TZ1D) support 3A maximum current compared to 2.1A for LCMGA160808T151RG. This provides additional design margin in high-current applications.

Q: Which substitute part offers the lowest DC resistance?

A: BLM18SG121TZ1D provides the lowest DC resistance at 25 mOhm, compared to 50 mOhm for the primary part and 30 mOhm for other substitutes. Lower DC resistance reduces power dissipation in the ferrite bead.

Q: Can these parts be used interchangeably in production?

A: Interchangeability depends on circuit design tolerance for impedance variation. The 30 Ohm impedance difference between the primary part (150 Ohm) and substitutes (120 Ohm) affects filtering performance. Electrical simulation or testing is required to confirm functional equivalence in specific applications.

Q: What is the operating temperature range for each part?

A: LCMGA160808T151RG and FBMH1608HM151-TV operate from -40°C to 125°C. The substitute parts (ABUP00160808121Y00, BLM18KG121TH1D, BLM18KG121TZ1D, BLM18SG121TZ1D) operate from -55°C to 125°C, providing extended low-temperature performance.

Q: Are there packaging format differences between the primary part and substitutes?

A: LCMGA160808T151RG and FBMH1608HM151-TV are supplied in Tape & Reel (TR) format. The Murata parts (BLM18KG121TH1D, BLM18KG121TZ1D, BLM18SG121TZ1D) are supplied in Cut Tape (CT) & Digi-Reel format.
