Substitute Part Grouping Explanation

Substitution of the PDU-S102 is determined by the following critical parameters:

• Manufacturer Continuity: Both the main part and substitute are manufactured by Advanced Photonix, ensuring design consistency and supply chain reliability.
• Package Compatibility: Both components utilize TO-5 metal can packages with through-hole mounting, enabling direct mechanical and electrical integration into existing PCB layouts.
• Operating Temperature Range: Identical operating temperature specification (-40°C ~ 125°C) ensures thermal compatibility across applications.
• Dark Current Performance: Both parts maintain 10pA typical dark current, meeting low-noise requirements.
• Mounting Type: Through-hole mounting is consistent across both components.

The PDU-V114 serves as the manufacturer-recommended substitute for the obsolete PDU-S102, as indicated in the original part's substitution field.

Engineering Selection Recommendations

The PDU-V114 is the manufacturer-designated substitute for the obsolete PDU-S102. Selection of the PDU-V114 provides the following advantages:

• Active Product Status: The PDU-V114 maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• RoHS Compliance: The PDU-V114 is RoHS compliant, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.
• Improved Performance Characteristics: The PDU-V114 delivers faster response time (13ns versus 50ns) and higher maximum reverse voltage rating (75V versus 20V), providing enhanced operational margins.
• Thermal Compatibility: Identical operating temperature range ensures direct thermal compatibility.
• Mounting Compatibility: Both components utilize through-hole mounting in TO-5 metal can packages, supporting direct PCB integration.

Applications requiring ultraviolet spectral sensitivity in the 200nm to 400nm range must evaluate the PDU-V114's extended spectral range (350nm ~ 1100nm) to confirm suitability for specific wavelength requirements.

Frequently Asked Questions (FAQ)

Q: Can the PDU-V114 directly replace the PDU-S102 in existing designs?

A: The PDU-V114 is the manufacturer-recommended substitute and shares identical operating temperature range, dark current performance, and through-hole TO-5 metal can packaging. However, the extended spectral range (350nm ~ 1100nm versus 200nm ~ 400nm) and different active area dimensions must be evaluated against specific application requirements before implementation.

Q: What are the key differences between PDU-S102 and PDU-V114?

A: Primary differences include spectral range, response time, maximum reverse voltage, active area dimensions, viewing angle, and RoHS compliance status. The PDU-V114 offers faster response time (13ns), higher voltage rating (75V), and RoHS compliance, while the PDU-S102 provides a narrower ultraviolet spectral range optimized for 200nm to 400nm applications.

Q: Is the PDU-V114 suitable for ultraviolet detection applications?

A: The PDU-V114 spectral range begins at 350nm, which overlaps the upper portion of the ultraviolet spectrum. Applications requiring detection below 350nm must verify that the PDU-V114's spectral characteristics meet specific wavelength requirements.

Q: Are there any package compatibility concerns when substituting the PDU-V114 for the PDU-S102?

A: Both components utilize through-hole TO-5 metal can packages with identical mounting type. The PDU-V114 features a lens top variant, which may affect optical coupling characteristics in applications with specific optical path requirements.

Q: What is the inventory status of these components?

A: The PDU-S102 has 844 pieces in stock as new original inventory. The PDU-V114 has 1007 pieces in stock as new original inventory. Both components are available through Advanced Photonix distribution channels.
