Key Parameters

Substitute Part Grouping Explanation

Substitution of the VTP100H is determined by the following critical parameters:

• Wavelength Compatibility: The substitute must operate within or overlap the 725nm ~ 1150nm spectral range to maintain sensor responsivity in the near-infrared region.
• Mounting Configuration: Through-hole radial mounting is required for mechanical compatibility with existing PCB layouts.
• Reverse Voltage Rating: The substitute must support the system's reverse bias voltage requirements.
• Dark Current Performance: Lower dark current values indicate superior signal-to-noise characteristics.
• Active Area: Larger active areas provide increased light collection efficiency.
• Viewing Angle: The substitute's field of view must accommodate the application's optical geometry.
• Operating Temperature Range: The substitute must function within the specified thermal environment.
• Regulatory Compliance: RoHS compliance status ensures environmental and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The PDB-C134F serves as a manufacturer-recommended substitute for the VTP100H. Both components share through-hole radial mounting configurations and operate within overlapping spectral ranges suitable for near-infrared applications.

The PDB-C134F offers the following characteristics relative to the VTP100H:

• Product Status: Active production status ensures long-term availability and supply chain continuity.
• Regulatory Compliance: ROHS3 compliance exceeds the RoHS Compliant status of the VTP100H, providing enhanced environmental standards alignment.
• Dark Current: The PDB-C134F exhibits significantly lower dark current (2nA versus 30nA), resulting in improved signal integrity and reduced noise floor.
• Reverse Voltage: The PDB-C134F operates at a maximum reverse voltage of 100V, which is lower than the VTP100H's 140V rating. System design must confirm compatibility with this reduced voltage specification.
• Active Area: The PDB-C134F features a smaller active area (1.538mm² versus 7.45mm²), which may affect light collection efficiency in applications requiring wide-angle sensitivity.
• Viewing Angle: The PDB-C134F provides a 30° viewing angle compared to the VTP100H's 140° angle. Applications requiring wide-angle detection must evaluate this parameter carefully.
• Operating Temperature: The PDB-C134F operates to 80°C maximum, compared to the VTP100H's 100°C upper limit. High-temperature applications must verify thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can the PDB-C134F directly replace the VTP100H in all applications?

A: The PDB-C134F is manufacturer-recommended as a substitute but differs in several parameters. The reduced viewing angle (30° versus 140°), smaller active area (1.538mm² versus 7.45mm²), lower maximum reverse voltage (100V versus 140V), and lower maximum operating temperature (80°C versus 100°C) must be evaluated against specific application requirements. Mechanical compatibility with the radial package configuration is confirmed.

Q: What are the key differences in optical performance?

A: Both components operate in the near-infrared spectrum with overlapping spectral ranges. The VTP100H is optimized for 925nm detection with a 140° field of view and larger active area, while the PDB-C134F is optimized for 950nm detection with a narrower 30° field of view and smaller active area. The PDB-C134F provides superior dark current performance (2nA versus 30nA).

Q: Are there electrical compatibility concerns?

A: The PDB-C134F's maximum reverse voltage rating of 100V is lower than the VTP100H's 140V rating. System designs operating at reverse voltages exceeding 100V require alternative solutions. The PDB-C134F's lower maximum operating temperature (80°C versus 100°C) must be verified for thermal environments approaching or exceeding 80°C.

Q: What is the package compatibility status?

A: Both components use through-hole radial mounting. The VTP100H uses a side-view configuration, while the PDB-C134F uses a 3mm diameter (T-1) radial package. Physical footprint and mounting hole alignment must be verified before implementation.

Q: How do the spectral characteristics compare?

A: The VTP100H spectral range is 725nm ~ 1150nm centered at 925nm. The PDB-C134F spectral range is 700nm ~ 1100nm centered at 950nm. Both ranges overlap significantly in the near-infrared region. The 25nm wavelength shift may affect responsivity in applications with narrow-band optical filtering.
