LMMCG201208T8R0NG Equivalent & Substitute Parts

Part Overview

The LMMCG201208T8R0NG is a power line ferrite bead manufactured by Taiyo Yuden, designed for electromagnetic interference (EMI) suppression in single-line applications. This 0805 (2012 Metric) surface mount component operates at 8 Ohms impedance at 100 MHz with a maximum current rating of 4A and minimal DC resistance of 8mOhm. The part maintains active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LMMCG201208T8R0NG are qualified based on strict equivalence of the following critical parameters:

• Impedance @ Frequency: 8 Ohms @ 100 MHz
• Current Rating (Max): 4A
• DC Resistance (DCR) (Max): 8mOhm
• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 125°C
• Filter Type: Power Line
• Number of Lines: 1

All identified substitute parts maintain identical electrical performance characteristics and mechanical compatibility with the original part specification. Substitution is determined solely by matching these parameters without consideration of series designation or manufacturer branding.

Parameter Comparison

Engineering Selection Recommendations

LMMCG201208T8R0NG (Primary Part): Active product status with full design support. ROHS3 compliant and suitable for new designs and production applications.

FBMJ2125HL8R0NT: Parametrically equivalent across all electrical and mechanical specifications. Designated as "Not For New Designs," indicating this part is in mature or end-of-life phase. Selection of this substitute should be limited to legacy system maintenance or where existing inventory is available.

LSMCG201208T8R0NG: Active product status with full design support. Parametrically equivalent to the primary part across all critical parameters. Suitable for new designs and production applications as a direct substitute.

Frequently Asked Questions (FAQ)

Q: Can FBMJ2125HL8R0NT be used in new product designs? A: FBMJ2125HL8R0NT is designated "Not For New Designs." While electrically and mechanically equivalent, this part should not be selected for new development. Use LMMCG201208T8R0NG or LSMCG201208T8R0NG for new designs.

Q: Are all substitute parts pin-compatible with the original LMMCG201208T8R0NG? A: Yes. All substitute parts share identical package specifications (0805/2012 Metric), mounting type (Surface Mount), and physical dimensions (0.079" L x 0.049" W, 1.05mm max height), ensuring direct PCB layout compatibility.

Q: What electrical parameters must remain constant for substitution? A: Impedance (8 Ohms @ 100 MHz), current rating (4A), DC resistance (8mOhm), and operating temperature range (-40°C ~ 125°C) must remain constant. All qualified substitutes maintain these specifications.

Q: Is there a difference in compliance between substitute parts? A: All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited). Compliance certifications are equivalent across all parts.

Q: Can substitute parts be mixed in the same production batch? A: Yes. All substitute parts meet identical electrical and mechanical specifications. However, design documentation should specify the approved part number(s) for traceability and supply chain management.
