Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSF-LXH555GD-5V is determined by the following critical parameters:

Optical Characteristics: Color (Green), wavelength range (peak 565nm), and lens type (Diffused) must be maintained for visual indication consistency.

Electrical Characteristics: Forward voltage (5.0V nominal) and current rating (12mA) establish the operating point. Substitute parts must operate within compatible voltage and current ranges to function in existing circuit designs without modification.

Mechanical Compatibility: Mounting type (Through Hole, Right Angle) and lens style (Round with Domed Top) ensure physical fit within the PCB layout and enclosure design.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for continued use in regulated applications.

The TLPG5600 from Vishay Semiconductor Opto Division is identified as a substitute part based on matching color, diffused lens type, through-hole right-angle mounting, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SSF-LXH555GD-5V is classified as Obsolete. The TLPG5600 is classified as Active, ensuring continued availability and supply chain support for new production or replacement requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component use in regulated markets.

Electrical Operating Point: The TLPG5600 operates at a forward voltage of 2.4V typical, which differs from the 5.0V rating of the SSF-LXH555GD-5V. Circuit designs utilizing the SSF-LXH555GD-5V must be evaluated to determine if the lower forward voltage of the TLPG5600 is compatible with existing current-limiting resistor values and power supply configurations.

Optical and Mechanical Compatibility: Both parts share identical peak wavelength (565nm), green diffused lens type, round domed top lens style, and through-hole right-angle mounting configuration. These parameters ensure functional equivalence for visual indication applications.

Viewing Angle Difference: The TLPG5600 provides a 160° viewing angle compared to the 60° viewing angle of the SSF-LXH555GD-5V. This wider viewing angle may affect the intended visual indication characteristics in applications where directional visibility is specified.

Frequently Asked Questions (FAQ)

Q: Can the TLPG5600 be used as a direct replacement for the SSF-LXH555GD-5V without circuit modification?

A: The TLPG5600 shares the same mounting type, lens style, and optical wavelength as the SSF-LXH555GD-5V. However, the forward voltage differs (2.4V vs. 5.0V). Direct substitution requires circuit evaluation to confirm that existing current-limiting resistor values and power supply configurations remain appropriate for the lower forward voltage of the TLPG5600.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: color and wavelength (green, 565nm peak), lens type (diffused), lens style (round with domed top), mounting configuration (through-hole, right-angle), and regulatory compliance status (ROHS3, REACH unaffected). Electrical parameters (forward voltage and current) must be evaluated for circuit compatibility.

Q: How does the viewing angle difference affect substitution?

A: The SSF-LXH555GD-5V provides a 60° viewing angle, while the TLPG5600 provides a 160° viewing angle. In applications where directional visibility is critical, the wider viewing angle of the TLPG5600 may alter the intended visual indication characteristics. Application requirements must be assessed to determine if this difference is acceptable.

Q: Are both parts compliant with current regulatory standards?

A: Both the SSF-LXH555GD-5V and TLPG5600 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.

Q: What is the significance of the Obsolete status of the SSF-LXH555GD-5V?

A: Obsolete status indicates that the SSF-LXH555GD-5V is no longer manufactured or supported by Lumex Opto/Components Inc. The TLPG5600, classified as Active, ensures continued availability and supply chain reliability for ongoing production or replacement applications.
