MTPS2085BWS Equivalent & Substitute Parts

Part Overview

The MTPS2085BWS is an infrared (IR) emitter operating at 855nm wavelength, designed for point source applications requiring 80mA forward current. Manufactured by Marktech Optoelectronics, this component is housed in a TO-18-2 package with a 10° viewing angle and operates across -30°C to 100°C. The product status is obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTPS2085BWS is determined by the following critical electrical and mechanical parameters:

• Wavelength: Must be 855nm to maintain spectral compatibility with receiver optics and system design
• Forward Current (If): Must support 80mA maximum rating for circuit compatibility
• Package Type: Must be TO-18-2 to ensure mechanical fit and thermal characteristics
• Mounting Type: Must be Through Hole to match PCB design requirements
• Forward Voltage (Vf): Acceptable variance within typical circuit design margins

The MTPS3085P-C meets these core substitution criteria while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MTPS3085P-C is the direct substitute for the obsolete MTPS2085BWS based on matching electrical specifications (855nm wavelength, 80mA forward current, TO-18-2 package). The substitute offers active product status, ensuring continued availability and supply chain reliability.

Key considerations for selection:

• Viewing Angle Difference: The MTPS3085P-C features a 4° viewing angle compared to the original 10°. This narrower beam concentration may require optical system re-evaluation depending on application requirements.
• Operating Temperature Range: The substitute operates within -20°C to 85°C versus the original -30°C to 100°C. Verify compatibility with system thermal specifications.
• Compliance: The MTPS3085P-C carries RoHS Compliant and REACH Unaffected certifications, meeting modern regulatory requirements.
• Forward Voltage: The 0.1V increase (1.9V to 2V) is within acceptable circuit design margins for most applications.

Frequently Asked Questions (FAQ)

Q: Can MTPS3085P-C directly replace MTPS2085BWS in existing designs?

A: Yes, for applications where the operating temperature range of -20°C to 85°C is acceptable and the narrower 4° viewing angle meets optical requirements. The matching wavelength (855nm), forward current (80mA), and TO-18-2 package ensure electrical and mechanical compatibility.

Q: What is the impact of the 10° to 4° viewing angle change?

A: The narrower viewing angle concentrates radiant intensity into a smaller solid angle. Applications requiring wide-angle IR emission may need optical redesign or alternative components with wider beam patterns.

Q: Is the 0.1V forward voltage difference significant?

A: The increase from 1.9V to 2V is typically accommodated within standard circuit design margins. Verify that the power supply and current-limiting resistor design can tolerate this variance.

Q: What are the compliance advantages of MTPS3085P-C?

A: The substitute is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The original MTPS2085BWS compliance status is not specified.

Q: Are there inventory considerations?

A: MTPS3085P-C is actively manufactured with 1517 pieces in stock (Bulk packaging), compared to the obsolete MTPS2085BWS with 1082 pieces remaining. Active product status ensures long-term availability.

Q: Does the TO-18-2 Metal Can package differ from standard TO-18-2?

A: Both use the TO-18-2 form factor. The "Metal Can" designation indicates the package construction material. Mechanical fit and thermal characteristics remain compatible for through-hole mounting applications.
