Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTPD1346D-080 is determined by the following critical parameters:

• Wavelength: 1300nm (primary detection wavelength)
• Spectral Range: 800nm ~ 1750nm (operational bandwidth)
• Diode Type: PIN (photodiode architecture)
• Package / Case: TO-46-3 Lens Top Metal Can (physical and electrical interface)
• Mounting Type: Through Hole (PCB integration method)
• Operating Temperature: -40°C ~ 85°C (thermal operating window)
• Voltage - DC Reverse (Vr) (Max): 5 V (maximum reverse bias specification)

The MTPD1346D-100 qualifies as a substitute part within the same 1346 InGaAs series, maintaining identical wavelength, spectral range, diode type, package configuration, mounting type, and operating temperature specifications. The primary difference is the active area diameter (1.00mm versus 0.80mm) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The MTPD1346D-100 is the direct substitute for the MTPD1346D-080 within the Marktech Optoelectronics 1346 InGaAs photodiode series. Both components share identical core optical and electrical specifications, including wavelength, spectral range, diode type, package configuration, and operating temperature range.

The MTPD1346D-100 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The component is ROHS3 compliant, meeting current environmental and regulatory requirements. The active area diameter increase from 0.80mm to 1.00mm represents a geometric variation that may affect light collection efficiency and responsivity characteristics; however, this parameter was not specified in the original part data and should be evaluated against specific application requirements.

Both components carry identical export control classification (EAR99) and tariff codes (8541.49.1050), confirming regulatory equivalence for procurement and logistics purposes.

Frequently Asked Questions (FAQ)

Q: Can the MTPD1346D-100 be used as a direct replacement for the MTPD1346D-080?

A: Yes. Both components are PIN photodiodes operating at 1300nm wavelength within the same spectral range (800nm ~ 1750nm), with identical maximum reverse voltage (5V), operating temperature range (-40°C ~ 85°C), and TO-46-3 lens top metal can package configuration. The active area diameter differs (1.00mm versus 0.80mm), which may impact light collection efficiency in specific optical configurations.

Q: What is the primary reason for substitution?

A: The MTPD1346D-080 is classified as obsolete. The MTPD1346D-100 maintains active product status, ensuring long-term availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: The MTPD1346D-100 is ROHS3 compliant, while compliance status for the MTPD1346D-080 was not specified. Both components share identical export control classification (EAR99) and tariff codes (8541.49.1050).

Q: How does the active area difference affect performance?

A: The active area diameter increase from 0.80mm to 1.00mm affects the light collection area. This geometric variation may influence responsivity and light coupling efficiency in applications with specific optical alignment or fiber coupling requirements. Application-specific testing is necessary to confirm suitability.
