PDB-C155SM Equivalent & Substitute Parts

Part Overview

The PDB-C155SM is a surface mount photodiode sensor manufactured by Advanced Photonix, classified as an optical sensor in the blue wavelength range. The device is currently listed with obsolete product status, which necessitates identification of functionally equivalent alternatives for ongoing applications requiring photodiode sensing capabilities. Substitute parts must maintain compatibility with surface mount assembly processes and preserve the core photodiode functionality.

Key Parameters

Substitute Part Grouping Explanation

The PDB-C165 qualifies as a substitute for the PDB-C155SM based on the following alignment of critical parameters:

• Both devices are manufactured by Advanced Photonix and classified as optical sensors
• Both employ surface mount technology, ensuring compatibility with existing PCB assembly processes
• Both are assigned identical ECCN (EAR99) and HTSUS (8541.49.1050) classifications
• Both maintain MSL rating of 1 (Unlimited), indicating equivalent moisture handling requirements
• The PDB-C165 is active product status, providing long-term availability compared to the obsolete PDB-C155SM

The substitution is based on functional category equivalence and manufacturing compatibility rather than spectral parameter matching, as spectral data for the PDB-C155SM is not provided in the source documentation.

Engineering Selection Recommendations

The PDB-C165 is the designated substitute for the obsolete PDB-C155SM. Selection of the PDB-C165 provides the following advantages:

• Active product status ensures continued availability and supply chain stability
• RoHS compliance of the PDB-C165 aligns with modern regulatory requirements, whereas the PDB-C155SM is non-compliant
• Identical export classification and tariff codes maintain regulatory consistency
• Surface mount packaging compatibility eliminates redesign requirements for PCB assembly

Frequently Asked Questions (FAQ)

Q: Can the PDB-C165 be used as a direct replacement for the PDB-C155SM?

A: The PDB-C165 is functionally equivalent within the optical sensor category and maintains identical mounting technology (surface mount) and regulatory classifications. Both devices share MSL 1 rating and EAR99 export classification.

Q: What are the key differences between these parts?

A: The primary differences are product status (PDB-C155SM is obsolete; PDB-C165 is active) and RoHS compliance (PDB-C155SM is non-compliant; PDB-C165 is compliant). The PDB-C165 provides 950nm wavelength specification and additional electrical parameters not documented for the PDB-C155SM.

Q: Are there packaging considerations for substitution?

A: Both parts use surface mount technology. The PDB-C165 is specified as 2-SMD, No Lead packaging. Verification of footprint compatibility with existing PCB designs is required before implementation.

Q: Does the PDB-C165 maintain the same regulatory classifications?

A: Yes. Both parts share identical ECCN (EAR99) and HTSUS (8541.49.1050) classifications, ensuring consistent export and tariff treatment.
