Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1090DX1-28V is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 28V (exact match required)
• Lamp Type: Incandescent (functional technology)
• Lamp Color: Red (optical output specification)
• Lens Color: Red (visual consistency)
• Panel Cutout Shape and Dimensions: Round, 0.50" (12.70mm) (mechanical fit requirement)
• Lens Style: Round with Domed Top (form factor)
• Termination Style: Wire Leads - 4.6" (116.84mm) (electrical connection method)
• Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory requirement)

The 1090A1-28V meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The 1090A1-28V serves as a direct parametric equivalent for the 1090DX1-28V across all specified electrical, mechanical, and compliance parameters. Both components are legacy products: the main part is classified as obsolete, while the substitute is designated as not for new designs. Both maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for existing installations.

Selection of the 1090A1-28V is appropriate for replacement applications where the 1090DX1-28V is no longer available. The substitute maintains identical voltage rating, panel cutout dimensions, termination configuration, and optical characteristics, ensuring direct functional compatibility within existing panel assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 1090A1-28V replace the 1090DX1-28V in existing installations?

A: Yes. The 1090A1-28V is a parametric equivalent with identical voltage rating (28V), panel cutout dimensions (0.50" round), wire lead length (4.6"), lens style (round domed top), and lamp/lens color (red). Direct substitution is supported.

Q: What are the critical parameters that must match for substitution?

A: Voltage rating, lamp type, lamp color, lens color, panel cutout shape and dimensions, lens style, wire lead length, and compliance certifications must all match. The 1090A1-28V satisfies all these requirements.

Q: Are there packaging differences between these parts?

A: The 1090DX1-28V is supplied with standard packaging, while the 1090A1-28V is supplied in bulk packaging. This difference does not affect functional compatibility or electrical performance.

Q: What is the inventory status of these parts?

A: The 1090DX1-28V has 973 pieces in stock. The 1090A1-28V has 1040 pieces in stock. Both are available as new original components.

Q: Are both parts compliant with current regulations?

A: Yes. Both the 1090DX1-28V and 1090A1-28V are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
