LLMCA201208T330RG Equivalent & Substitute Parts

Part Overview

The LLMCA201208T330RG is a 33 Ohm ferrite bead manufactured by Taiyo Yuden, designed for power line filtering applications in 0805 (2012 Metric) surface mount packages. This component operates at 100 MHz impedance with a maximum current rating of 4A and DC resistance of 8mOhm. The part is currently in active production status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameters. Alternative sources and packaging formats may be required based on inventory availability or design phase requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLMCA201208T330RG is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Impedance value: 33 Ohms @ 100 MHz
• Current rating: 4A maximum
• DC resistance: 8mOhm maximum

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Mounting method: Surface Mount
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Maximum height: 0.041" (1.05mm)

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• Operating temperature range: -40°C ~ 125°C

Parts meeting all electrical, mechanical, and compliance criteria are classified as parametric equivalents. Variations in product status, packaging format (Tape & Reel versus Cut Tape), or manufacturer do not affect functional substitutability when all specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

LSMCA201208T330RG (Taiyo Yuden, LSMC series) is the preferred substitute for new designs. This part maintains identical electrical specifications, operating temperature range, and RoHS3 compliance. Both the main part and this substitute are in active production status. The difference in packaging format (Tape & Reel) does not affect functional performance.

742792012 (Würth Elektronik, WE-CBF series) is an active alternative from a different manufacturer. This part meets all electrical and mechanical requirements with an extended lower operating temperature limit (-55°C versus -40°C), providing additional thermal margin. The Cut Tape & Digi-Reel® packaging format is suitable for production environments with appropriate handling equipment.

Secondary Substitutes (Limited Availability):

FBMJ2125HM330-T (Taiyo Yuden, FB series) is electrically and mechanically equivalent but carries a "Not For New Designs" status. This part is suitable only for legacy system maintenance or replacement applications where the original part number is no longer available.

Z0805C330BPWST (KEMET, Z-PWS series) is electrically and mechanically equivalent but is classified as obsolete. This part should not be selected for new designs or long-term production applications.

All substitute parts listed maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can LSMCA201208T330RG be used as a direct replacement for LLMCA201208T330RG?

A: Yes. Both parts share identical electrical parameters (33 Ohms @ 100 MHz, 4A current rating, 8mOhm DCR), mechanical specifications (0805 package, surface mount), and compliance certifications (ROHS3, MSL 1). Both are in active production status. The only difference is the series designation (LSMC versus LLMC) and internal design, which do not affect functional performance.

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 pick-and-place assembly systems. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, typically used for lower-volume applications or manual assembly. Both formats contain identical components; the difference is in delivery and handling method only.

Q: Why is FBMJ2125HM330-T marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. While electrically and mechanically equivalent, Taiyo Yuden recommends using LSMCA201208T330RG or LLMCA201208T330RG for new product development to ensure long-term availability and supply chain stability.

Q: Can Z0805C330BPWST be used in production?

A: Z0805C330BPWST is classified as obsolete and should not be selected for new designs or ongoing production. This part may have limited inventory and no guaranteed future availability. Use LSMCA201208T330RG or 742792012 instead.

Q: Does 742792012 have different performance characteristics?

A: 742792012 maintains identical electrical performance and mechanical compatibility. The operating temperature range extends to -55°C (versus -40°C for the main part), providing additional low-temperature margin. This part is suitable for applications requiring extended temperature performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), matching the compliance profile of LLMCA201208T330RG.

Q: What determines whether a ferrite bead can substitute for another?

A: Substitution is determined by equivalence across impedance value, frequency, current rating, DC resistance, package type, physical dimensions, and operating temperature range. All listed substitutes meet these criteria for the LLMCA201208T330RG.
