Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB1608T100M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Current rating: 60 mA minimum
• DC resistance: 700 mOhm
• Self resonant frequency: 32 MHz
• Test frequency: 2.52 MHz

Mechanical & Physical Parameters:

• Package / Case: 0603 (1608 Metric)
• Mounting type: Surface Mount
• Core material: Ferrite
• Shielding: Unshielded
• Operating temperature range: -40°C to 105°C

Compliance & Environmental Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts must match all electrical specifications, maintain identical package dimensions and mounting characteristics, and satisfy all compliance requirements. Packaging format (Cut Tape vs. Tape & Reel) does not affect electrical or mechanical compatibility and is determined by procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

The LSQBA160808T100M is a direct electrical and mechanical equivalent to the LB1608T100M. All critical electrical parameters, physical dimensions, and environmental operating specifications are identical. Both components are manufactured by Taiyo Yuden and satisfy ROHS3 compliance and REACH requirements.

The primary distinction between these parts is product status and packaging format. The LB1608T100M is designated "Not For New Designs," while the LSQBA160808T100M carries "Active" status, indicating ongoing manufacturer support and availability. The LSQBA160808T100M is supplied in Tape & Reel (TR) format, whereas the LB1608T100M is available in Cut Tape (CT) & Digi-Reel® format. Packaging format selection depends on assembly process requirements and procurement specifications and does not affect component performance or compatibility.

For applications requiring the 10 µH, 60 mA, 700 mOhm inductor in 0603 surface mount package, the LSQBA160808T100M provides equivalent electrical performance with the advantage of active product status and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the LSQBA160808T100M be used as a direct replacement for the LB1608T100M?

A: Yes. The LSQBA160808T100M is electrically and mechanically equivalent to the LB1608T100M. All electrical parameters (inductance, current rating, DC resistance, frequency characteristics), physical dimensions, and environmental specifications are identical. Both components are surface mount 0603 (1608 Metric) package inductors with ferrite cores and unshielded construction.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel are packaging and delivery formats that do not affect component electrical or mechanical properties. Cut Tape is supplied in individual strips, while Tape & Reel is supplied on continuous reels for automated assembly. Selection depends on assembly process requirements and procurement volume.

Q: Why is the LB1608T100M marked "Not For New Designs"?

A: "Not For New Designs" indicates the manufacturer has superseded this part number in their product line. The LSQBA160808T100M is the active equivalent. For new designs and ongoing production, the LSQBA160808T100M is recommended due to active manufacturer status and continued availability.

Q: Are there any compliance differences between these parts?

A: No. Both the LB1608T100M and LSQBA160808T100M are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). Compliance certifications are equivalent.

Q: Will the LSQBA160808T100M fit in the same PCB footprint as the LB1608T100M?

A: Yes. Both components have identical physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.035" (0.90mm). PCB footprints and assembly processes require no modification.

Q: Are the inductance tolerance and frequency characteristics identical?

A: Yes. Both parts have ±20% inductance tolerance, 32 MHz self resonant frequency, and 2.52 MHz inductance test frequency. Electrical performance characteristics are equivalent across all specified parameters.
