Substitute Part Grouping Explanation

Substitution eligibility for the LTV-355T-D is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 3750Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio range: 600% to 7500% @ 1mA
• Voltage - Output (Max): 35V
• Current - Output / Channel: 80mA
• Vce Saturation (Max): 1V
• Operating Temperature Range: -55°C ~ 110°C
• Package / Case: 4-SMD, Gull Wing
• Supplier Device Package: 4-SOP
• Mounting Type: Surface Mount

The LTV-355T qualifies as a parametric equivalent to the LTV-355T-D. Both parts share identical electrical specifications and mechanical packaging. The primary distinction is packaging format: LTV-355T-D is supplied in standard packaging, while LTV-355T is supplied in Tape & Reel (TR) format. This difference does not affect component functionality or performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LTV-355T-D and LTV-355T are active production components from Lite-On Inc. with full ROHS3 compliance and identical electrical performance specifications. Selection between these parts should be based on procurement requirements:

The LTV-355T-D is suitable for applications requiring standard packaging formats with smaller order quantities. The LTV-355T in Tape & Reel format is appropriate for high-volume automated assembly operations where reel-based component feeding is standard practice. Both parts meet the same functional and compliance requirements for circuit integration.

Frequently Asked Questions (FAQ)

Q: Can LTV-355T replace LTV-355T-D in production assemblies?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: LTV-355T-D uses standard packaging while LTV-355T uses Tape & Reel format. Circuit performance and specifications are unchanged.

Q: What is the significance of the packaging format difference?

A: Packaging format affects handling and assembly processes. Tape & Reel (TR) format is optimized for automated pick-and-place assembly equipment, while standard packaging is used for manual assembly or lower-volume applications. The component itself functions identically regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both LTV-355T-D and LTV-355T are ROHS3 compliant and suitable for applications with RoHS requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

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

A: Yes. Both parts use identical 4-SOP surface mount packages with Gull Wing leads. PCB footprints, solder reflow profiles, and placement parameters are identical.
