Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5503609 is determined by the following critical parameters:

• Mounting Type: Through Hole, Right Angle (mechanical compatibility with PCB layout)
• Lens Size: 5.00mm diameter (physical form factor constraint)
• Color Capability: Green and Yellow wavelengths (functional requirement)
• Lens Type: Diffused (optical characteristic)
• Configuration: Single LED (electrical architecture)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental rating)
• Regulatory Compliance: REACH Unaffected, ECCN EAR99 (trade and environmental compliance)

The Lumex Opto/Components Inc. SSF-LXH139YGW meets these substitution criteria through matching mounting configuration, lens size, color options, and regulatory status. Voltage and current specifications are not provided for the substitute part; however, the mechanical and functional parameters align with the original component's design requirements.

• Environmental Rating: Matching MSL 1 (Unlimited) rating ensures equivalent moisture handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the Lumex SSF-LXH139YGW be used as a direct replacement for the Dialight 5503609?

A: Yes. Both components share identical mounting type (through hole, right angle), lens size (5.00mm), color options (green and yellow), and lens type (diffused). The mechanical and functional parameters required for PCB integration are equivalent.

Q: What are the key differences between these parts?

A: The primary difference is product status: the Dialight 5503609 is obsolete, while the Lumex SSF-LXH139YGW is active. The Lumex part additionally includes white color capability and ROHS3 Compliant certification. Voltage and current specifications are not provided for the Lumex part in the available data.

Q: Are there packaging considerations for substitution?

A: The Dialight 5503609 is specified with "-" packaging notation, while the Lumex SSF-LXH139YGW is supplied in Bulk packaging. Confirm bulk packaging compatibility with your procurement and assembly processes.

Q: Do both parts meet the same environmental and regulatory requirements?

A: Yes. Both components are REACH Unaffected, carry EAR99 classification, and maintain MSL 1 (Unlimited) moisture sensitivity rating. The Lumex part additionally meets ROHS3 Compliant standards.

Q: What parameters determine substitution eligibility for this LED indicator?

A: Substitution is determined by mounting type (through hole, right angle), lens size (5.00mm diameter), color capability (green and yellow), lens type (diffused), configuration (single), and regulatory compliance status (REACH and ECCN classification).
