Key Parameters

Substitute Part Grouping Explanation

The MTD3910N qualifies as a direct substitute for the MTD3010N based on the following critical parameters:

• Wavelength Compatibility: Both components operate at 900nm primary wavelength
• Voltage Rating: Identical maximum DC reverse voltage of 30 V
• Dark Current: Matching typical dark current specification of 10nA
• Operating Temperature Range: Identical range of -30°C to 100°C
• Mounting Configuration: Both utilize through-hole mounting
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Manufacturer: Both manufactured by Marktech Optoelectronics

The MTD3910N represents an active product status alternative, whereas the MTD3010N is obsolete. The substitute maintains electrical and thermal compatibility while offering improved availability and active manufacturer support.

Engineering Selection Recommendations

The MTD3910N is the appropriate substitute for the MTD3010N based on product lifecycle and compliance status. The MTD3010N is classified as obsolete, creating supply chain risk and limiting access to manufacturer technical support. The MTD3910N maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Both components share identical maximum voltage ratings, dark current specifications, and operating temperature ranges, establishing direct electrical compatibility. The MTD3910N package designation (TO-18-2 Metal Can) differs from the MTD3010N, requiring mechanical verification for board-level integration. Through-hole mounting compatibility is maintained across both variants.

Frequently Asked Questions (FAQ)

Q: Can MTD3910N directly replace MTD3010N in existing designs?

A: Electrical compatibility is established through matching voltage ratings (30 V maximum), dark current (10nA), and operating temperature range (-30°C to 100°C). Package configuration differs (TO-18 versus TO-18-2 Metal Can), requiring mechanical fit verification on the PCB.

Q: What is the significance of the spectral range difference between these parts?

A: The MTD3010N spectral range extends to 1100nm, while the MTD3910N extends to 1060nm. Both cover the 900nm primary wavelength and the 400nm lower boundary. The 40nm difference at the upper range limit does not affect substitution for 900nm applications.

Q: Why is product status important for component selection?

A: The MTD3010N is obsolete, indicating discontinued manufacturing and limited inventory availability. The MTD3910N is active, ensuring ongoing production, manufacturer support, and compliance with current regulatory standards including ROHS3.

Q: Are there package considerations for board redesign?

A: The MTD3910N uses TO-18-2 Metal Can packaging while the MTD3010N uses TO-18 packaging. Both are through-hole mounted, but physical dimensions and pin configurations require verification against PCB footprint specifications before implementation.

Q: Does RoHS compliance affect substitution decisions?

A: The MTD3910N carries ROHS3 compliance certification. If the application requires RoHS compliance, the MTD3910N meets this requirement. The MTD3010N compliance status is not specified in available documentation.
