Dialight 5530233 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530233 is a 3mm bi-level yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a diffused, tinted lens with a domed top and operates at 1.8V with a 2mA current rating. The part is currently listed as obsolete, making identification of suitable equivalent components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5530233 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Configuration: 2 High (bi-level)
• Color: Yellow (x 2)
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused
• Current Rating: 2mA

Allowable Variation Parameters:

• Voltage Rating: ±0.2V tolerance acceptable (1.8V nominal)
• Wavelength - Peak: ±10nm tolerance acceptable (583nm nominal)
• Millicandela Rating: ±0.5mcd tolerance acceptable (1.6mcd nominal)
• Viewing Angle: Variation acceptable if not specified in original design
• Product Status: Active substitutes preferred for obsolete parts

Two substitute parts meet these criteria: the Dialight 5530233F (direct manufacturer variant) and the Bivar Inc. H201CYDL (cross-manufacturer equivalent).

Parameter Comparison

Engineering Selection Recommendations

Dialight 5530233F is the primary substitute for the obsolete Dialight 5530233. This part maintains identical electrical specifications (1.8V, 2mA, 1.6mcd) and mechanical form factor while offering active product status and ROHS3 compliance. The wavelength variance of 2nm (585nm vs. 583nm) and viewing angle specification of 60° fall within acceptable tolerances for bi-level indicator applications. Packaging differs (bulk vs. original specification), which may require supply chain adjustment.

Bivar Inc. H201CYDL serves as a cross-manufacturer equivalent when Dialight 5530233F availability is constrained. This part maintains the 2 High bi-level configuration, 2mA current rating, and 3mm T-1 form factor. The voltage rating increases to 2V (0.2V above nominal), wavelength shifts to 590nm (7nm above nominal), and millicandela rating increases to 2mcd. These variations remain within acceptable engineering tolerances for indicator applications. ROHS3 compliance is confirmed; REACH status is not specified in available documentation.

Both substitutes are suitable for production use based on product status and regulatory compliance. Selection between them should be based on supply availability, packaging requirements, and circuit design voltage tolerance.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5530233F directly replace the obsolete 5530233 without circuit modification?

A: Yes. The 5530233F maintains identical voltage (1.8V), current (2mA), and brightness (1.6mcd) specifications. The 2nm wavelength difference and 60° viewing angle specification do not require circuit redesign for standard indicator applications.

Q: What is the voltage tolerance when using the Bivar H201CYDL as a substitute?

A: The H201CYDL operates at 2V nominal, compared to the original 1.8V specification. This 0.2V increase is within standard engineering tolerance for LED indicator circuits. Circuit design must accommodate this voltage rating; no modification is required if the original design includes appropriate current-limiting resistors.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Dialight 5530233F and Bivar H201CYDL are ROHS3 compliant. The original 5530233 RoHS status is not specified in available documentation.

Q: How do the viewing angles differ between the main part and substitutes?

A: The original 5530233 does not specify a viewing angle. The 5530233F provides 60° viewing angle, and the H201CYDL provides 40° viewing angle. Both are suitable for standard circuit board indicator applications where viewing angle is not a critical design parameter.

Q: What packaging differences exist between these parts?

A: The original 5530233 packaging is not specified. The 5530233F is supplied in bulk packaging, and the H201CYDL is supplied in tray packaging. Packaging selection may affect procurement, handling, and assembly processes.

Q: Is the lens tint difference between 5530233F and H201CYDL significant?

A: The 5530233F maintains the diffused, tinted lens of the original part. The H201CYDL uses a diffused lens without tint specification. For applications where lens tint affects light transmission or color perception, the 5530233F is the preferred substitute.

Q: Can these parts be used interchangeably in existing inventory?

A: The 5530233F is the direct equivalent and can be used interchangeably. The H201CYDL is a functional equivalent suitable for new designs or applications where the 5530233F is unavailable. Existing designs should be evaluated for voltage tolerance before substituting the H201CYDL.
