Key Parameters

Substitute Part Grouping Explanation

The OP830WSL has been identified as a functionally equivalent substitute based on the following criteria:

Common Qualifying Parameters:

• Operating Temperature Range: Both components operate across -55°C ~ 125°C
• Mounting Type: Both are through-hole mounted components
• RoHS Compliance: Both meet RoHS requirements (SD3410-002 is RoHS Compliant; OP830WSL is ROHS3 Compliant)
• Moisture Sensitivity Level: Both are classified as MSL 1 (Unlimited)
• ECCN Classification: Both are classified as EAR99

Substitution Logic: The OP830WSL is a phototransistor-based optical sensor that provides equivalent functional performance for 880nm detection applications. While the SD3410-002 is a photodiode and the OP830WSL is a phototransistor, both devices serve as light-sensitive detectors in the near-infrared spectrum. The OP830WSL's maximum collector current (50mA) and power rating (250mW) provide sufficient operational headroom for applications previously served by the SD3410-002. The through-hole package configuration and identical operating temperature range ensure mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Product Status: The SD3410-002 is classified as obsolete, while the OP830WSL is in active production status. This distinction is critical for long-term component availability and supply chain continuity. Selection of the OP830WSL ensures access to current manufacturing, quality assurance processes, and ongoing inventory availability.

Compliance Alignment: Both components meet current environmental and regulatory standards. The OP830WSL carries ROHS3 compliance, which represents the current iteration of RoHS requirements, providing assurance of compliance with evolving regulatory frameworks.

Operational Compatibility: The identical operating temperature range (-55°C ~ 125°C) and moisture sensitivity classification (MSL 1) ensure that the OP830WSL can be deployed in environments previously served by the SD3410-002 without modification to thermal management or storage protocols.

Package Consideration: While both components use through-hole mounting, the package styles differ (TO-46 versus TO-206AA/TO-18-3). Physical footprint and lead spacing must be verified against the specific PCB layout before implementation.

Frequently Asked Questions (FAQ)

Q: Can the OP830WSL directly replace the SD3410-002 without circuit modifications?

A: The OP830WSL is functionally equivalent for 880nm optical detection applications and operates across the same temperature range. However, circuit-level integration depends on the specific application design. The OP830WSL is a phototransistor (current amplification device), while the SD3410-002 is a photodiode (linear response device). Signal conditioning and biasing circuits may require adjustment to accommodate the different device characteristics.

Q: What is the significance of the different package types (TO-46 vs. TO-206AA)?

A: Package type affects physical dimensions, lead spacing, and PCB footprint. TO-46 and TO-206AA are both through-hole packages but have different mechanical profiles. PCB layout compatibility must be verified before component substitution. Lead-to-lead spacing and mounting hole diameter should be confirmed against the original design specifications.

Q: Are there any compliance differences between the two components?

A: Both components are RoHS compliant and classified as EAR99 for export purposes. The OP830WSL carries ROHS3 certification, which is the current standard, while the SD3410-002 is listed as RoHS Compliant. Both meet MSL 1 (Unlimited) moisture sensitivity requirements, indicating identical handling and storage protocols.

Q: Why is the SD3410-002 classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this component. This classification necessitates identification of active alternatives to ensure continued system support, maintenance, and future production capability.

Q: What inventory considerations apply to this substitution?

A: The SD3410-002 has 858 pieces in current stock (new original condition), while the OP830WSL has 1,714 pieces available. The OP830WSL's higher inventory level and active production status provide greater long-term availability assurance for ongoing procurement requirements.

Q: How do the electrical specifications compare for signal processing applications?

A: The OP830WSL specifies maximum collector current (50mA) and power dissipation (250mW), while the SD3410-002 specifies dark current (250nA) and response time (75µs). Both parameters are provided in the component datasheets and should be evaluated against specific application requirements for signal-to-noise ratio and temporal response characteristics.
