Engineering Selection Recommendations

The PDB-V104 is the manufacturer-recommended substitute for the obsolete PDB-C207. Selection of the PDB-V104 provides the following advantages:

Product Availability: The PDB-V104 is in active production status with 692 units in stock, whereas the PDB-C207 is obsolete with limited remaining inventory.

Regulatory Compliance: The PDB-V104 is RoHS Compliant, meeting current environmental and regulatory requirements for new designs and procurement. The PDB-C207 is RoHS non-compliant.

Operating Range: The PDB-V104 extends the operating temperature range to -40°C ~ 125°C, providing broader environmental compatibility compared to the PDB-C207 range of -20°C ~ 80°C.

Performance Characteristics: The PDB-V104 delivers improved response time (13ns versus 100ns) and lower dark current (150pA versus 1nA), resulting in enhanced signal-to-noise performance in optical sensing applications.

Frequently Asked Questions (FAQ)

Q: Can the PDB-V104 be used as a direct replacement for the PDB-C207 in existing designs?

A: Yes. Both components share identical wavelength (950nm), diode type (PIN), and package format (TO-46-2 Metal Can). The PDB-V104 maintains mechanical and electrical compatibility for direct substitution in through-hole mounting applications.

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

A: The PDB-V104 offers faster response time (13ns versus 100ns), lower dark current (150pA versus 1nA), larger active area (3.09mm² versus 0.33mm²), and wider viewing angle (65° versus 49°). The PDB-V104 also supports a broader operating temperature range (-40°C ~ 125°C versus -20°C ~ 80°C) and is RoHS Compliant.

Q: Are there any circuit design considerations when switching from PDB-C207 to PDB-V104?

A: The maximum reverse voltage rating differs: PDB-C207 is rated at 100V while PDB-V104 is rated at 75V. Designs operating near the 100V limit require verification that the 75V maximum of the PDB-V104 remains within acceptable operating margins. The improved response time and lower dark current of the PDB-V104 may allow optimization of transimpedance amplifier designs.

Q: Why is the PDB-C207 obsolete?

A: The PDB-C207 is listed as obsolete by the manufacturer. The PDB-V104 represents the current active product offering for 950nm PIN photodiode applications in TO-46-2 packaging.

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

A: The PDB-V104 has a larger active area (3.09mm²) compared to the PDB-C207 (0.33mm²). This larger collection area improves light gathering capability and signal strength. Applications requiring the smaller active area of the original part should evaluate whether the increased active area affects optical coupling or system performance.
