MTPS8085P Infrared Emitter 850nm - Equivalent & Substitute Parts

Part Overview

The MTPS8085P is an infrared (IR) emitter operating at 850nm wavelength, designed for point source applications requiring high-intensity IR output. Manufactured by Marktech Optoelectronics, this component delivers 100mA forward current with a narrow 5° viewing angle in a TO-18-2 metal can package.

The MTPS8085P is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTPS8085P is determined by strict alignment of the following electrical and mechanical parameters:

• Wavelength: Must be 850nm (infrared spectrum requirement)
• Forward Current Rating: Must be 100mA (circuit design constraint)
• Forward Voltage: Must be 1.7V typical (power supply compatibility)
• Viewing Angle: Must be 5° (optical design requirement)
• Package Type: Must be TO-18-2 Metal Can (mechanical fit and thermal characteristics)
• Mounting Type: Must be Through Hole (PCB assembly compatibility)

The MTPS8085P-C meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MTPS8085P-C is the direct substitute for the obsolete MTPS8085P. Both components share identical electrical and mechanical specifications across all critical parameters: 850nm wavelength, 100mA forward current, 1.7V forward voltage, 5° viewing angle, and TO-18-2 metal can packaging.

The MTPS8085P-C offers additional advantages: active product status ensures ongoing availability, RoHS compliance meets modern regulatory requirements, and an extended operating temperature range (-30°C to 100°C) provides greater thermal margin compared to the original part (-20°C to 85°C).

For new designs and production applications, the MTPS8085P-C is the recommended selection. Existing designs using the MTPS8085P can transition to the MTPS8085P-C without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the MTPS8085P-C be used as a direct replacement for the MTPS8085P?

A: Yes. The MTPS8085P-C is a direct equivalent. All electrical parameters (wavelength, forward current, forward voltage, viewing angle) and mechanical specifications (package type, mounting method) are identical. The substitute part is manufactured by the same supplier and maintains full compatibility with existing circuit designs.

Q: What is the difference between the MTPS8085P and MTPS8085P-C?

A: The primary differences are product status and packaging format. The MTPS8085P is obsolete; the MTPS8085P-C is active production. The MTPS8085P-C is RoHS compliant and features an extended operating temperature range (-30°C to 100°C versus -20°C to 85°C). Electrical and optical performance are identical.

Q: Are there any thermal or reliability differences between these parts?

A: Both parts use identical TO-18-2 metal can packaging and are rated for the same forward current (100mA). The MTPS8085P-C supports a wider operating temperature range, which may provide additional thermal margin in extreme environments. No other reliability differences are specified.

Q: What packaging options are available for the MTPS8085P-C?

A: The MTPS8085P-C is supplied in bulk packaging. The MTPS8085P was available in standard packaging format. Both use the same component package (TO-18-2 Metal Can) for PCB assembly.

Q: Is the MTPS8085P-C suitable for new product designs?

A: Yes. The MTPS8085P-C is the recommended choice for new designs. Active product status ensures long-term availability, RoHS compliance meets current regulatory standards, and the extended temperature range provides design flexibility.
