LBMCG201208T8R0NG Equivalent & Substitute Parts

Part Overview

The LBMCG201208T8R0NG is a power line ferrite bead manufactured by Taiyo Yuden, designed for electromagnetic interference (EMI) suppression in single-line applications. This component operates at 8 Ohms impedance at 100 MHz with a maximum current rating of 4A and is housed in a 0805 (2012 Metric) surface mount package. The part maintains Active product status and is fully RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the same performance envelope.

Engineering Selection Recommendations

LBMCG201208T8R0NG (Primary Part): Maintains Active product status with full manufacturing support. Recommended for new designs and long-term production applications. Current inventory: 985 pieces.

LSMCG201208T8R0NG (Preferred Substitute): Maintains Active product status with equivalent electrical and mechanical specifications. Suitable for direct substitution in new designs and production. Higher inventory availability: 5054 pieces. REACH Unaffected certification provided.

FBMJ2125HL8R0NT (Secondary Substitute): Designated as Not For New Designs. Suitable only for legacy system maintenance, repair, or retrofit applications where the original part number must be replaced. Higher inventory availability: 5200 pieces. REACH Unaffected certification provided.

Selection between LBMCG201208T8R0NG and LSMCG201208T8R0NG for new designs should be based on supply chain availability and procurement lead times, as both maintain Active status and identical performance characteristics. FBMJ2125HL8R0NT should be reserved for non-new-design applications only.

Frequently Asked Questions (FAQ)

Q: Can LSMCG201208T8R0NG be used as a direct replacement for LBMCG201208T8R0NG in new designs?

A: Yes. Both parts are manufactured by Taiyo Yuden with Active product status and identical electrical specifications (8 Ohms @ 100 MHz, 4A, 8mOhm DCR). The 0805 package footprint, operating temperature range, and compliance certifications are equivalent. Direct substitution is permissible in new designs.

Q: Why is FBMJ2125HL8R0NT marked as "Not For New Designs"?

A: FBMJ2125HL8R0NT carries a Not For New Designs designation from the manufacturer. While it meets all electrical and mechanical parameters required for substitution, it is intended for legacy system support and repair applications only. For new product development, LBMCG201208T8R0NG or LSMCG201208T8R0NG are the appropriate selections.

Q: Are there any package or footprint differences between these three parts?

A: No. All three parts use the 0805 (2012 Metric) surface mount package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum height (0.041" / 1.05mm). PCB layout and assembly processes remain unchanged across all three part numbers.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). LSMCG201208T8R0NG and FBMJ2125HL8R0NT carry REACH Unaffected certification. All parts are classified under ECCN EAR99.

Q: Can these ferrite beads be used interchangeably in power line filtering applications?

A: Yes, within the specified operating parameters. All three parts are rated for power line filtering with 1-line configuration, 4A maximum current, and 8 Ohms impedance at 100 MHz. Thermal and electrical performance remain consistent across the operating temperature range of -40°C to 125°C.
