Dialight 5530333 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530333 is a dual-level LED circuit board indicator featuring a 3mm T-1 through-hole right-angle package with yellow (585nm peak wavelength) diffused, tinted lens. Designed for 5V applications at 10mA operating current, this component delivers 12.6mcd brightness in a round domed-top configuration suitable for PCB mounting.

The 5530333 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5530333 is determined by strict equivalence across the following critical parameters:

• Color and wavelength (Yellow, 585nm peak)
• Electrical specifications (5V, 10mA, 12.6mcd)
• Physical form factor (3mm T-1, round domed-top lens, diffused tinted)
• Mounting configuration (through-hole, right-angle orientation)
• Moisture sensitivity classification (MSL 1)

The substitute parts 5530333F and 5530333300F maintain identical electrical and optical characteristics. Both are active-status components manufactured by Dialight within the 553 series, ensuring direct functional compatibility with the obsolete 5530333.

Parameter Comparison

Engineering Selection Recommendations

Both 5530333F and 5530333300F are direct functional equivalents to the obsolete 5530333. Selection between these active-status alternatives is based on the following criteria:

5530333F is suitable for applications where viewing angle specification is not critical. This part maintains full electrical and optical compatibility with the original design.

5530333300F provides an additional specification parameter with a defined 60° viewing angle, offering enhanced clarity on optical performance characteristics. This part is recommended for applications where viewing angle documentation is required for compliance or design verification purposes.

Both substitute parts carry ROHS3 compliance certification, ensuring alignment with current environmental and regulatory standards. Packaging availability differs between the two options; verify packaging requirements against your procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can 5530333F and 5530333300F be used interchangeably with the original 5530333?

A: Yes. Both parts maintain identical electrical specifications (5V, 10mA), optical output (12.6mcd, 585nm yellow), physical form factor (3mm T-1 through-hole right-angle), and lens characteristics (diffused, tinted, round domed-top). Direct substitution is supported without circuit modification.

Q: What is the difference between 5530333F and 5530333300F?

A: The primary difference is the documented viewing angle specification. 5530333300F specifies a 60° viewing angle, while 5530333F does not include this parameter. Both parts are electrically and optically identical. The difference reflects packaging or documentation variants within the Dialight 553 series.

Q: Why is the original 5530333 marked as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation by the supplier. Active-status equivalents (5530333F and 5530333300F) ensure continued availability and supply chain continuity for this component category.

Q: Are there any compliance differences between the substitute parts and the original?

A: The substitute parts carry explicit ROHS3 compliance certification. Both maintain REACH Unaffected status and EAR99 export classification consistent with the original part. MSL rating (1 - Unlimited) and HTSUS classification (8541.41.0000) remain unchanged.

Q: What packaging options are available for the substitute parts?

A: Both 5530333F and 5530333300F are supplied in bulk packaging. Confirm packaging requirements with your procurement department to ensure compatibility with your assembly process.
