TSUS6202 Equivalent & Substitute Parts

Part Overview

The TSUS6202 is an infrared (IR) emitter operating at 950nm wavelength with a maximum forward current of 150mA and typical forward voltage of 1.3V. This radial through-hole component is designed for applications requiring near-infrared emission in the 950nm spectrum. The TSUS6202 is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSUS6202 is determined by the following critical parameters:

• Wavelength compatibility: The substitute must operate within the near-infrared spectrum. The TSUS6202 operates at 950nm; substitutes operating at adjacent wavelengths (such as 940nm) are acceptable where system design permits wavelength tolerance.
• Mounting type and package: Both the main part and substitute must use through-hole radial mounting to ensure mechanical and electrical compatibility with existing PCB layouts.
• Current and voltage ratings: The substitute must support the required forward current and voltage characteristics of the application circuit.
• Operating temperature range: The substitute must maintain performance across the specified operating temperature range of -40°C to 85°C.
• Compliance and availability: The substitute must meet RoHS3 compliance and be available in active production status.

The TSAL6200 meets these substitution criteria as an active, RoHS3-compliant infrared emitter with radial through-hole packaging and overlapping operating temperature specifications.

Engineering Selection Recommendations

The TSAL6200 is the recommended substitute for the obsolete TSUS6202. Both components are manufactured by Vishay Semiconductor Opto Division and maintain ROHS3 compliance. The TSAL6200 is in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

• The TSAL6200 operates at 940nm compared to the TSUS6202's 950nm, representing a 10nm wavelength difference within the near-infrared spectrum.
• The TSAL6200 has a maximum forward current rating of 100mA versus the TSUS6202's 150mA. Circuit design must accommodate this lower current rating.
• The TSAL6200 exhibits higher radiant intensity (40mW/sr @ 100mA) compared to the TSUS6202 (20mW/sr @ 100mA), providing improved optical output at equivalent current levels.
• Both components share identical operating temperature ranges and through-hole radial mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the TSAL6200 directly replace the TSUS6202 in existing designs?

A: Direct replacement is possible if the application circuit accommodates the TSAL6200's maximum forward current of 100mA and the 10nm wavelength difference at 940nm. PCB layout compatibility is maintained due to identical radial through-hole mounting.

Q: What is the significance of the wavelength difference between 950nm and 940nm?

A: The 10nm difference places both emitters within the near-infrared spectrum. System performance depends on detector sensitivity at these wavelengths. Applications with wavelength-specific detector requirements must evaluate compatibility.

Q: How do the radiant intensity values compare?

A: The TSAL6200 provides 40mW/sr @ 100mA versus the TSUS6202's 20mW/sr @ 100mA. This represents a 2x increase in radiant intensity at equivalent current levels, resulting in stronger optical output.

Q: Are there any compliance or supply chain advantages to using the TSAL6200?

A: The TSAL6200 is in active production status with high inventory availability (563,840 pcs), whereas the TSUS6202 is obsolete. Both maintain ROHS3 compliance and identical operating temperature specifications.

Q: What circuit modifications are necessary for substitution?

A: The primary consideration is the reduced maximum forward current (100mA vs. 150mA). Circuit current-limiting resistors and power supply design must be evaluated to ensure operation within the TSAL6200's ratings.
