LSMGG160808T221RG Equivalent & Substitute Parts

Part Overview

The LSMGG160808T221RG is a 220 Ohm power line ferrite bead manufactured by Taiyo Yuden in 0603 (1608 Metric) surface mount package. This component is designed for electromagnetic interference (EMI) suppression in single-line power applications with a maximum current rating of 900mA and DC resistance of 170mOhm. The part is currently in Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary part experiences inventory constraints, extended lead times, or when design flexibility permits selection from equivalent alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of ferrite bead components is determined by strict equivalence across electrical performance and mechanical compatibility parameters. The LSMGG160808T221RG can be substituted with the FBMH1608HL221-T based on the following critical parameters:

Electrical Equivalence Criteria:

• Impedance specification: 220 Ohms @ 100 MHz (identical)
• Current rating: 900mA maximum (identical)
• DC resistance: 170mOhm maximum (identical)
• Filter type: Power Line (identical)
• Number of lines: 1 (identical)

Mechanical Compatibility Criteria:

• Package designation: 0603 (1608 Metric) (identical)
• Mounting type: Surface Mount (identical)
• Operating temperature range: -40°C ~ 125°C (identical)
• Height specification: 0.035" (0.90mm) maximum (identical)

Compliance & Environmental Criteria:

• RoHS3 compliance (both parts)
• Moisture sensitivity level: MSL 1 (Unlimited) (both parts)
• ECCN classification: EAR99 (both parts)

The FBMH1608HL221-T is classified as "Not For New Designs" but remains electrically and mechanically equivalent for existing applications or where inventory availability requires substitution.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The LSMGG160808T221RG is the recommended selection as it maintains Active product status with full manufacturer support and ongoing availability. This part is suitable for all new circuit implementations requiring 220 Ohm power line ferrite bead functionality in 0603 package format.

For Existing Designs or Inventory Constraints: The FBMH1608HL221-T provides complete electrical and mechanical equivalence and may be utilized when the primary part experiences supply limitations. Although classified as "Not For New Designs," this substitute maintains identical performance specifications and compliance certifications (RoHS3, MSL 1, EAR99).

Compliance Considerations: Both parts satisfy RoHS3 compliance requirements and carry unlimited moisture sensitivity rating (MSL 1), eliminating moisture-related handling constraints. Both parts are classified under ECCN EAR99 and HTSUS 8548.00.0000 for regulatory purposes.

Frequently Asked Questions (FAQ)

Q: Can FBMH1608HL221-T be used as a direct replacement for LSMGG160808T221RG?

A: Yes. The FBMH1608HL221-T is electrically and mechanically equivalent. Both parts provide identical impedance (220 Ohms @ 100 MHz), current rating (900mA), DC resistance (170mOhm), package format (0603/1608 Metric), and operating temperature range (-40°C ~ 125°C). The primary difference is product status; FBMH1608HL221-T is classified as "Not For New Designs."

Q: What are the dimensional differences between these parts?

A: Both parts share identical height specifications (0.035" / 0.90mm maximum). The length and width dimensions are functionally equivalent: LSMGG160808T221RG measures 0.063" L x 0.031" W (1.60mm x 0.80mm), while FBMH1608HL221-T measures 0.063" L x 0.032" W (1.60mm x 0.80mm). This 0.001" (0.01mm) width variation is within standard manufacturing tolerance and does not affect PCB footprint compatibility.

Q: Are there compliance or certification differences?

A: No. Both parts carry identical compliance certifications: RoHS3 compliant, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8548.00.0000. Both parts are suitable for applications requiring environmental and regulatory compliance.

Q: Why is FBMH1608HL221-T marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status within the manufacturer's product portfolio. However, the part remains fully functional and available. The designation does not imply technical deficiency or performance degradation.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts utilize identical 0603 (1608 Metric) surface mount package format with matching footprint requirements. No PCB layout modifications are necessary for substitution.

Q: What is the maximum current these ferrite beads can handle?

A: Both parts are rated for 900mA maximum current. DC resistance is specified at 170mOhm maximum, which determines voltage drop characteristics under load conditions.

Q: Are there inventory differences between these parts?

A: Yes. LSMGG160808T221RG currently has 1046 pieces in stock, while FBMH1608HL221-T has 8400 pieces available. Inventory levels may influence substitution decisions when supply constraints exist.
