Dialight 5530311 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530311 is a 3mm bi-level red LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a diffused, tinted lens with a domed top, rated for 5V operation at 10mA with a peak wavelength of 635nm and 29mcd brightness output. The main part number 5530311 carries an obsolete product status, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives within the 553 series provide direct functional equivalence with improved availability and current manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5530311 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Voltage rating (5V), operating current (10mA), wavelength (635nm), and brightness output (29mcd) must remain identical
• Physical Configuration: Lens size (3mm, T-1), lens type (diffused, tinted), lens style (round with domed top), and mounting type (through-hole, right-angle) must match exactly
• Functional Classification: Bi-level red LED circuit board indicator configuration (2 High) must be preserved
• Environmental Compliance: MSL rating (1), REACH status, and ECCN classification must align

All substitute parts listed—5530311010F, 5530311200F, 5530311300F, 5530311306F, and 5530311F—maintain complete electrical and mechanical equivalence to the main part number. These alternatives differ only in packaging format (bulk) and product status (active vs. obsolete), with no functional or performance variations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the obsolete 5530311. Selection among the active alternatives should be based on the following factors:

Product Status: The main part number 5530311 is obsolete. All substitute parts (5530311010F, 5530311200F, 5530311300F, 5530311306F, 5530311F) carry active product status, ensuring continued manufacturing support and availability.

Compliance: All substitute parts are ROHS3 compliant, providing enhanced environmental compliance compared to the main part number. All maintain REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory alignment across jurisdictions.

Availability: Inventory levels vary across substitute options. Part 5530311F offers the highest stock level at 1241 pieces, followed by 5530311200F at 1009 pieces. Selection may be influenced by procurement lead time requirements and supply chain considerations.

Packaging: All substitute parts are supplied in bulk packaging format, differing from the main part number specification. Packaging format does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 5530311 with any of the listed substitute parts?

A: Yes. All substitute parts maintain complete electrical and mechanical equivalence. They are direct replacements with identical voltage ratings (5V), operating current (10mA), wavelength (635nm), brightness output (29mcd), lens specifications (3mm T-1 diffused tinted round domed top), and mounting configuration (through-hole right-angle). The only differences are product status (active vs. obsolete) and packaging format (bulk).

Q: What is the difference between 5530311F and the other substitute parts?

A: All substitute parts are functionally identical. Differences exist only in part number designation and packaging specifications. Part 5530311F serves as the base product number for the active series, while 5530311010F, 5530311200F, 5530311300F, and 5530311306F represent variant designations within the same functional family. Selection should be based on availability and procurement requirements rather than technical performance.

Q: Are the substitute parts ROHS compliant?

A: Yes. All substitute parts are ROHS3 compliant. The main part number 5530311 does not specify RoHS status. This represents an improvement in environmental compliance for new designs or production runs.

Q: Does the viewing angle specification affect substitution?

A: The main part number 5530311 does not specify a viewing angle. Substitute parts 5530311010F, 5530311200F, 5530311300F, and 5530311306F specify 60° viewing angle. Part 5530311F does not specify viewing angle, matching the main part number specification. All parts maintain identical optical performance characteristics (29mcd brightness, 635nm wavelength, diffused tinted lens).

Q: What is the MSL rating and does it affect substitution?

A: All parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. This specification is identical across the main part and all substitutes, confirming full compatibility for storage, handling, and assembly processes.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically identical. They can be used interchangeably within the same circuit board assembly without performance variation or compatibility issues.
