Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTD3610D3 is determined by strict equivalence across the following critical parameters:

• Wavelength: 940nm (primary detection wavelength)
• Spectral Range: 400nm ~ 1060nm (optical response bandwidth)
• Responsivity @ nm: 0.45 A/W @ 660nm (photoelectric conversion efficiency)
• Voltage - DC Reverse (Vr) (Max): 20 V (maximum reverse bias rating)
• Current - Dark (Typ): 10nA (dark current specification)
• Operating Temperature: -20°C ~ 85°C (thermal operating envelope)
• Moisture Sensitivity Level (MSL): 2 (1 Year) (moisture handling requirement)

The MTD3910D3 meets all these critical parameters while maintaining active product status and full compliance with current regulatory standards. Substitution is valid based on electrical and environmental equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MTD3910D3 is the direct equivalent substitute for the obsolete MTD3610D3. Both components are manufactured by Marktech Optoelectronics and share identical electrical specifications across all critical parameters: wavelength, spectral range, responsivity, reverse voltage rating, dark current, and operating temperature range.

The MTD3910D3 offers the advantage of active product status, ensuring continued availability and supply chain support. The component is ROHS3 compliant, meeting current environmental and regulatory requirements. The radial through-hole mounting configuration of the MTD3910D3 provides a standard form factor suitable for conventional PCB assembly methods.

Selection of the MTD3910D3 eliminates obsolescence risk while maintaining full electrical and environmental compatibility with the original MTD3610D3 specification.
