TS8514VA Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The TS8514VA is an infrared (IR) emitter operating at 850nm wavelength, designed for surface mount applications requiring 100mA forward current capability. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability. The TS8514VA delivers 1.6V forward voltage with a 120° viewing angle, suitable for IR transmission applications in consumer and industrial equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS8514VA is determined by strict alignment of the following electrical and mechanical parameters:

• Wavelength: 850nm (exact match required)
• Forward Current Rating: 100mA (exact match required)
• Forward Voltage: 1.6V typical (exact match required)
• Viewing Angle: 120° (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: ROHS3 Compliant (maintained)

The VSMY3850-GS08 meets all substitution criteria as an active product from the same manufacturer (Vishay Semiconductor Opto Division) with identical electrical specifications and surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

The VSMY3850-GS08 is the manufacturer-recommended substitute for the obsolete TS8514VA. Both components maintain ROHS3 compliance and identical electrical performance at rated conditions. The VSMY3850-GS08 is an active product with confirmed inventory availability, eliminating supply chain risk associated with the obsolete TS8514VA.

The operating temperature upper limit of the VSMY3850-GS08 is 85°C compared to 100°C for the TS8514VA. Applications requiring sustained operation above 85°C ambient temperature must evaluate thermal management or seek alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the VSMY3850-GS08 directly replace the TS8514VA in existing designs?

A: Yes, for applications operating within the -40°C to 85°C temperature range. The electrical specifications (wavelength, forward current, forward voltage, viewing angle) are identical. Packaging is surface mount in both cases, supporting direct PCB layout compatibility.

Q: What is the primary difference between these parts?

A: The TS8514VA is obsolete with no active manufacturing. The VSMY3850-GS08 is an active product from the same manufacturer with identical electrical performance. The VSMY3850-GS08 has a maximum operating temperature of 85°C versus 100°C for the TS8514VA.

Q: Are there packaging differences?

A: The TS8514VA is specified as a die package. The VSMY3850-GS08 is supplied in 2-SMD, J-Lead packaging with Tape & Reel (TR) standard packaging. Both are surface mount technologies suitable for automated assembly.

Q: What compliance certifications apply to the substitute?

A: The VSMY3850-GS08 maintains ROHS3 compliance, REACH Unaffected status, and carries ECCN classification EAR99.
