Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLMGG160808T471RG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Impedance @ Frequency: 470 Ohms @ 100 MHz
• Package / Case: 0603 (1608 Metric)
• Filter Type: Power Line
• Number of Lines: 1
• Operating Temperature Range: -40°C ~ 125°C
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating (Max): Minimum 600mA (higher ratings acceptable)
• DC Resistance (DCR) (Max): Maximum 350mOhm (lower values acceptable)
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT)
• Product Status: Active or Not For New Designs

Three substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

Primary Selection: LSMGG160808T471RG

The LSMGG160808T471RG is the preferred substitute for the LLMGG160808T471RG. Both parts are manufactured by Taiyo Yuden, share identical electrical specifications (470 Ohms @ 100 MHz, 600mA, 350mOhm DCR), and maintain Active product status. Mechanical dimensions are equivalent, with both parts measuring 0.063" L x 0.031" W. All compliance certifications including ROHS3 and MSL 1 are matched. This part is available in Tape & Reel packaging with 4922 pieces in stock.

Secondary Selection: FBMH1608HL471-T

The FBMH1608HL471-T is a Taiyo Yuden alternative with identical electrical and mechanical specifications. This part carries Not For New Designs status, indicating it is suitable for replacement or repair applications but not recommended for new product development. Inventory availability is significantly higher at 21380 pieces. Mechanical dimensions show a minor width variation (0.032" versus 0.031"), which remains within standard PCB assembly tolerances for 0603 components.

Tertiary Selection: Z0603C471BPWZT

The Z0603C471BPWZT is a KEMET-manufactured substitute with matching impedance and package specifications. This part exhibits superior electrical performance with 700mA current rating and 150mOhm DCR, both exceeding the original specification. However, this part carries Obsolete product status and is supplied in Cut Tape packaging rather than Tape & Reel format. Selection of this part is limited to applications where inventory depletion of primary options occurs and where the enhanced electrical performance is compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can LSMGG160808T471RG be used as a direct replacement for LLMGG160808T471RG?

A: Yes. Both parts are manufactured by Taiyo Yuden with identical impedance (470 Ohms @ 100 MHz), current rating (600mA), DC resistance (350mOhm), package dimensions (0603/1608 Metric), and operating temperature range (-40°C ~ 125°C). Both maintain Active product status and ROHS3 compliance. No circuit modifications are required.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or lower-volume applications. The Z0603C471BPWZT is supplied in Cut Tape format, which may require different handling procedures during assembly.

Q: Why is FBMH1608HL471-T marked as Not For New Designs?

A: This designation indicates the part is in mature or declining production status. The part remains fully functional and suitable for replacement, repair, or legacy system applications. For new product development, Taiyo Yuden recommends using LSMGG160808T471RG or LLMGG160808T471RG instead.

Q: Is the Z0603C471BPWZT with 150mOhm DCR better than the original 350mOhm specification?

A: The Z0603C471BPWZT exhibits lower DC resistance, which reduces power dissipation in the component. However, this part carries Obsolete status and is not recommended for new designs. Selection should be based on circuit requirements and supply availability rather than performance enhancement alone.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (FBMH1608HL471-T, LSMGG160808T471RG, and Z0603C471BPWZT) maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original LLMGG160808T471RG specifications.

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

A: Yes, within the specified electrical and mechanical parameters. All substitute parts are rated for power line filtering with single-line configuration, 470 Ohm impedance at 100 MHz, and surface mount installation on 0603 package footprints. Circuit board layout and assembly procedures remain unchanged.

Q: What is the significance of the 0.032" width dimension on FBMH1608HL471-T?

A: The FBMH1608HL471-T width of 0.032" compared to 0.031" on other parts represents a 0.001" (0.025mm) variation. This falls within standard PCB assembly tolerances for 0603 components and does not affect footprint compatibility or assembly processes.
