TSHA6200 Infrared Emitter 875nm Equivalent & Substitute Parts

Part Overview

The TSHA6200 is an infrared (IR) emitter operating at 875nm wavelength, designed for through-hole radial mounting applications. Manufactured by Vishay Semiconductor Opto Division, this component delivers 25mW/sr radiant intensity at 100mA forward current with a 24° viewing angle. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSHA6200 is determined by the following criteria:

Primary Compatibility Parameters:

• Wavelength range: 870nm–875nm (near-infrared spectrum alignment)
• Maximum forward current: 100mA (circuit current capacity match)
• Mounting type: Through Hole (mechanical compatibility)
• Operating temperature overlap: Minimum -40°C, maximum 85°C

Secondary Consideration Parameters:

• Package configuration (Radial vs. T 1 3/4 form factor affects PCB layout)
• Forward voltage tolerance (affects circuit design margins)
• Radiant intensity specifications (application-dependent performance requirement)

The substitute parts listed below meet the primary compatibility parameters. Package type differences require mechanical layout verification during integration.

Engineering Selection Recommendations

HSDL-4261 (Lite-On) — Preferred substitute for direct mechanical replacement. Radial package matches TSHA6200 form factor. Wavelength 870nm remains within near-infrared spectrum. Operating temperature range -40°C ~ 70°C covers lower bound of original specification. Active product status ensures supply continuity. ROHS3 compliant.

HSDL-4251 (Lite-On) — Suitable for applications where T 1 3/4 package is acceptable. Wavelength 870nm and 100mA maximum current align with primary parameters. Operating temperature range -40°C ~ 85°C matches original specification exactly. Higher radiant intensity (56mW/sr @ 100mA) may require circuit current adjustment. Active product status. ROHS3 compliant.

HSDL-4220 (Lite-On) — Acceptable for non-critical temperature applications. Wavelength 875nm provides exact spectral match. Operating temperature range 0°C ~ 70°C does not extend to -40°C lower bound. T 1 3/4 package requires layout modification. Active product status. ROHS3 compliant.

SIR-563ST3FN (Rohm Semiconductor) — Alternative for 940nm wavelength applications only. Wavelength shift to 940nm represents different spectral region and is not a direct substitute for 875nm systems. Lower radiant intensity (9mW/sr @ 50mA) indicates reduced optical output. T 1 3/4 package. Active product status. ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can HSDL-4261 replace TSHA6200 in existing designs without modification?

A: HSDL-4261 matches the radial package configuration and supports the same 100mA maximum forward current. Wavelength difference (870nm vs. 875nm) is within near-infrared spectrum tolerance for most applications. Forward voltage is significantly lower (1.4V vs. 2.8V), requiring circuit verification to confirm current-limiting resistor compatibility. Operating temperature range is -40°C ~ 70°C, which does not extend to the original 85°C maximum.

Q: What is the impact of wavelength variation between 870nm and 875nm?

A: Both wavelengths operate in the near-infrared region and are commonly used in IR sensing and transmission applications. Specific system performance depends on receiver photodiode spectral response. If the receiving component is optimized for 875nm, a 5nm shift to 870nm may result in reduced detection efficiency. System-level testing is necessary to confirm compatibility.

Q: Why does HSDL-4220 have a lower operating temperature minimum?

A: HSDL-4220 specifies 0°C ~ 70°C operating range, which does not include the -40°C lower bound of TSHA6200. This limits use in applications requiring extended cold-temperature operation. HSDL-4251 and HSDL-4261 both support -40°C minimum and are preferred for temperature-critical designs.

Q: How does the T 1 3/4 package differ from Radial in terms of integration?

A: Radial packages (TSHA6200, HSDL-4261) have leads extending from the component body in a radial pattern, suitable for specific PCB layouts. T 1 3/4 packages (HSDL-4220, HSDL-4251, SIR-563ST3FN) have axial lead configuration. Mechanical substitution requires PCB footprint redesign and potential circuit board layout modification.

Q: Is SIR-563ST3FN a suitable substitute for TSHA6200?

A: SIR-563ST3FN operates at 940nm wavelength, which is outside the 870–875nm range of the TSHA6200. This represents a different spectral region and is not a direct functional substitute. Use only if system design specifically requires 940nm wavelength operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TSHA6200 and all listed substitute parts (HSDL-4220, HSDL-4251, HSDL-4261, SIR-563ST3FN) are ROHS3 compliant, meeting environmental and regulatory requirements for current manufacturing standards.
