Engineering Selection Recommendations

The MTPD1346D-100 is the designated substitute for the obsolete MTPD1346C-080 based on the following engineering criteria:

• Series Continuity: Both components are part of the 1346 InGaAs product line from Marktech Optoelectronics, ensuring consistent optical and electrical performance characteristics within the InGaAs material system.
• Production Status: The MTPD1346D-100 maintains active production status with confirmed inventory availability (1382 Pcs), providing reliable long-term supply compared to the obsolete MTPD1346C-080.
• Regulatory Compliance: The substitute meets ROHS3 compliance requirements and carries EAR99 export classification, supporting modern procurement and regulatory standards.
• Package Compatibility: The TO-46-3 Lens Top Metal Can package is mechanically and electrically compatible with the original TO-46 form factor for through-hole mounting applications.
• Moisture Handling: Identical MSL rating of 1 (Unlimited) ensures equivalent handling, storage, and assembly requirements without additional process modifications.

Frequently Asked Questions (FAQ)

Q: Can the MTPD1346D-100 directly replace the MTPD1346C-080 in existing designs?

A: Yes. Both components share the same manufacturer series (1346 InGaAs), package family (TO-46), and moisture sensitivity classification. The TO-46-3 Lens Top Metal Can package is mechanically and electrically compatible with the original TO-46 package for through-hole mounting applications.

Q: What are the key differences between these two photodiodes?

A: The primary differences are product status and specified performance parameters. The MTPD1346D-100 is in active production with documented specifications including 1300nm wavelength, 800nm-1750nm spectral range, 1.00mm active area diameter, 200nA typical dark current, and -40°C to 85°C operating temperature range. The MTPD1346C-080 specifications for these parameters are not provided in the available documentation.

Q: Are there any compliance or certification differences?

A: The MTPD1346D-100 carries ROHS3 compliance certification and EAR99 export classification. The MTPD1346C-080 is marked as obsolete with no current compliance documentation. For new designs or procurement, the MTPD1346D-100 meets current regulatory requirements.

Q: What is the active area difference, and does it affect substitution?

A: The MTPD1346D-100 specifies a 1.00mm diameter active area. The MTPD1346C-080 active area is not documented. For applications where active area is a critical parameter, the documented 1.00mm specification of the substitute should be verified against original design requirements.

Q: Are there inventory considerations for this substitution?

A: The MTPD1346C-080 has 1072 pieces available as new original stock. The MTPD1346D-100 has 1382 pieces in active inventory. For long-term supply assurance, the active production status of the MTPD1346D-100 provides superior availability compared to the obsolete MTPD1346C-080.
