Parameter Comparison

Engineering Selection Recommendations

The H131CSGD-120 is the designated substitute for the obsolete H131CSGT-120 based on the following factors:

1. Active Product Status: The H131CSGD-120 is classified as Active, ensuring current availability and ongoing manufacturing support from Bivar Inc.

2. Regulatory Compliance: The H131CSGD-120 carries ROHS3 Compliance certification, meeting current environmental and material restriction standards required for new component sourcing.

3. Shared Classification: Both components are manufactured by Bivar Inc. and classified under the same ECCN (EAR99) and HTSUS (8541.41.0000) codes, confirming equivalent regulatory treatment.

4. Environmental Rating Consistency: Both parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating identical moisture handling requirements and suitability for standard storage and assembly processes.

For designs currently using the H131CSGT-120, transition to the H131CSGD-120 is supported by the manufacturer's substitution documentation and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the H131CSGD-120 directly replace the H131CSGT-120 in existing designs? A: The H131CSGD-120 is the manufacturer-specified substitute for the H131CSGT-120. Both components share the same base product line (H131) and regulatory classifications. Component selection should reference the actual circuit requirements for voltage, current, wavelength, and optical characteristics to confirm compatibility.

Q: What is the difference between packaging types for these components? A: The H131CSGT-120 is specified with packaging type "-" while the H131CSGD-120 uses Tray packaging. Tray packaging is standard for automated assembly processes. This difference does not affect electrical or optical performance but impacts material handling and processing workflows.

Q: Does the H131CSGD-120 meet the same environmental standards as the original part? A: Both the H131CSGT-120 and H131CSGD-120 share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). The H131CSGD-120 additionally carries ROHS3 Compliance certification, which meets stricter current environmental material restriction requirements.

Q: Why is the original part marked as Obsolete? A: Product discontinuation by manufacturers is standard in component lifecycle management. The H131CSGD-120, as the active substitute, ensures continued access to functionally equivalent components for system maintenance and new production requirements.
