Dialight 5530122 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5530122 is a 3mm LED circuit board indicator featuring a dual-level green configuration with diffused, tinted lens and right-angle through-hole mounting. Rated at 2.1V, 10mA with 16mcd brightness, this component is classified as obsolete. Due to its discontinued status, equivalent substitute parts from active product lines are necessary to maintain design continuity and ensure ongoing component availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5530122 is determined by the following critical parameters:

• Color and Configuration: Green (x 2) dual-level LED
• Current Rating: 10mA nominal operation
• Millicandela Rating: 16mcd brightness level
• Lens Characteristics: Diffused, tinted lens with round domed top
• Physical Package: 3mm T-1 form factor
• Mounting: Through-hole, right-angle orientation
• Voltage Tolerance: Operating voltage range 2.1V to 2.2V
• Wavelength Range: Peak wavelength 562nm to 563nm
• Regulatory Compliance: REACH Unaffected, EAR99 classification

All substitute parts maintain these core electrical and mechanical parameters, ensuring functional equivalence in circuit board indicator applications. Variations in viewing angle and lens specification details do not affect substitution validity when all primary parameters align.

Engineering Selection Recommendations

Primary Substitutes (Dialight Series 553):

The Dialight parts 5530122300F and 5530122F are direct substitutes with active product status and ROHS3 compliance. Both maintain identical electrical specifications (2.1V, 10mA, 16mcd, 563nm wavelength) and mechanical form factor. These parts are recommended as first-choice replacements due to manufacturer continuity and regulatory compliance certification.

Alternative Substitute (VCC 553-0122):

The Visual Communications Company part 553-0122 provides functional equivalence with active product status and ROHS3 compliance. This part operates at 2.2V (0.1V higher than the main part) and features a 90° viewing angle compared to the 45° specification of the Dialight active variants. The wavelength peak of 562nm remains within acceptable tolerance of the original 563nm specification. This part is suitable for applications where the increased viewing angle is beneficial or where voltage tolerance permits the 0.1V differential.

All substitute parts maintain MSL 1 rating, REACH Unaffected status, and EAR99 export classification, ensuring regulatory and environmental compliance equivalence with the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can I use 5530122300F or 5530122F as direct replacements for the obsolete 5530122?

A: Yes. Both Dialight parts 5530122300F and 5530122F are direct electrical and mechanical equivalents. They maintain identical voltage (2.1V), current (10mA), brightness (16mcd), wavelength (563nm), and physical form factor (3mm T-1 through-hole right-angle). The primary difference is product status: the original is obsolete while these are active production parts.

Q: What is the difference between 5530122300F and 5530122F?

A: Both parts are electrically and mechanically identical. The primary distinction is packaging designation. 5530122300F carries a bulk packaging code, while 5530122F includes a PC mount designation. Both are Dialight Series 553 components with active status and ROHS3 compliance. Selection between these two should be based on packaging and procurement requirements rather than technical performance.

Q: Can I substitute the VCC 553-0122 for the Dialight 5530122?

A: The VCC 553-0122 is functionally equivalent with the following considerations: it operates at 2.2V (0.1V higher than the 2.1V original), features a 90° viewing angle (versus unspecified on the original), and has a wavelength peak of 562nm (1nm lower than the 563nm original). These differences remain within acceptable tolerance for circuit board indicator applications. The part is ROHS3 compliant and maintains all regulatory equivalence.

Q: What parameters must remain constant for a part to be considered a valid substitute?

A: Valid substitutes must maintain: dual-level green configuration, 10mA current rating, 16mcd brightness, 3mm T-1 form factor, through-hole right-angle mounting, diffused tinted lens with round domed top, and operating voltage within 2.1V to 2.2V range. Wavelength peak must remain within 562nm to 563nm. Viewing angle and specific lens detail specifications may vary without affecting substitution validity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts (5530122300F, 5530122F, and 553-0122) carry ROHS3 compliance certification. The original obsolete part 5530122 does not specify RoHS status. All parts maintain REACH Unaffected status and EAR99 export classification.

Q: What is the inventory status of these substitute parts?

A: Current inventory levels are: 5530122300F (2,896 pcs), 5530122F (2,504 pcs), and 553-0122 (9,032 pcs). The VCC 553-0122 offers the highest available stock. All parts are listed as new original in stock.
