LLMGG160808T331RG Ferrite Bead Equivalent & Substitute Parts

Part Overview

The LLMGG160808T331RG is a 330 Ohm power line ferrite bead manufactured by Taiyo Yuden in 0603 (1608 Metric) surface mount package. This component operates at 100 MHz impedance with an 800mA current rating and 210mOhm maximum DC resistance. The part is classified as Active product status and is ROHS3 compliant with MSL 1 moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the ferrite bead category, including impedance specification, frequency rating, current capacity, package dimensions, and mounting type. Alternative sources and series variants provide design flexibility while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLMGG160808T331RG is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Impedance @ Frequency: 330 Ohms @ 100 MHz
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount
• Filter Type: Power Line
• Number of Lines: 1
• Operating Temperature Range: -40°C ~ 125°C

Allowable Variation Parameters:

• Current Rating (Max): 800mA minimum (higher ratings acceptable)
• DC Resistance (DCR) (Max): 210mOhm maximum (lower values acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)
• Manufacturer: Multiple qualified sources
• Product Status: Active or Not For New Designs

The identified substitute parts maintain full electrical and mechanical compatibility within these parameter boundaries. Dimensional tolerances on height and width remain within specified limits across all equivalent parts.

Engineering Selection Recommendations

LSMGG160808T331RG (Taiyo Yuden LSMG Series)

This substitute part is recommended for new designs. It maintains identical electrical specifications to the LLMGG160808T331RG with Active product status. The LSMG series variant provides equivalent performance with 2754 units in current inventory. All compliance certifications including ROHS3, REACH Unaffected, and MSL 1 rating are maintained.

FBMH1608HL331-T (Taiyo Yuden FB Series)

This part provides full electrical and mechanical equivalence but carries Not For New Designs product status. The FB series is suitable for legacy system support and replacement applications where existing designs require component continuity. Current inventory of 4188 units is available. All compliance requirements are satisfied.

Z0603C331BPWZT (KEMET Z-PWZ Series)

This KEMET-manufactured substitute offers superior DC resistance performance at 130mOhm maximum and higher current rating of 900mA. However, the part is classified as Obsolete product status. Selection of this part is limited to applications requiring specific KEMET sourcing or where superior DC resistance characteristics are critical. Cut Tape packaging format differs from standard Tape & Reel format. Current inventory of 4787 units is available.

Frequently Asked Questions (FAQ)

Q: Can LSMGG160808T331RG be used as a direct replacement for LLMGG160808T331RG?

A: Yes. Both parts are manufactured by Taiyo Yuden with identical impedance (330 Ohms @ 100 MHz), current rating (800mA), DC resistance (210mOhm), package dimensions (0603 / 1608 Metric), and operating temperature range (-40°C ~ 125°C). The LSMG series variant maintains full electrical and mechanical compatibility with Active product status.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically for smaller quantity requirements or manual assembly. The Z0603C331BPWZT uses Cut Tape format while other substitutes use Tape & Reel format.

Q: Why is FBMH1608HL331-T marked as Not For New Designs?

A: Product status indicates manufacturer recommendations for design phase selection. Not For New Designs status means the part remains available for support and replacement of existing applications but should not be selected for new circuit designs. LSMGG160808T331RG with Active status is the preferred choice for new designs.

Q: Is Z0603C331BPWZT suitable for new product development?

A: No. The Z0603C331BPWZT carries Obsolete product status, indicating the manufacturer has discontinued active support. While the part maintains electrical equivalence and current inventory exists, selection for new designs is not recommended. LSMGG160808T331RG or LLMGG160808T331RG are appropriate choices for new product development.

Q: What are the compliance differences between substitute parts?

A: All four parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. LSMGG160808T331RG and Z0603C331BPWZT include REACH Unaffected status documentation. FBMH1608HL331-T does not list REACH status in available specifications. All parts carry EAR99 ECCN and 8548.00.0000 HTSUS classification.

Q: Can the higher current rating of Z0603C331BPWZT (900mA vs 800mA) provide additional design margin?

A: The Z0603C331BPWZT current rating of 900mA exceeds the 800mA specification of the main part. However, circuit design should be based on the actual current requirements of the application. The higher rating does not alter impedance or DC resistance characteristics. Selection should prioritize product status and availability for the intended application phase.

Q: Are there dimensional compatibility concerns between substitute parts?

A: All substitute parts use 0603 (1608 Metric) package with 0.035" (0.90mm) maximum height. Width dimensions are 0.031" (0.80mm) for LLMGG160808T331RG, LSMGG160808T331RG, and Z0603C331BPWZT, and 0.032" (0.80mm) for FBMH1608HL331-T. These minor dimensional variations remain within standard 0603 package tolerances and do not affect PCB layout or assembly compatibility.
