Dialight 5611101050 LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5611101050 is a 5mm red LED circuit board indicator with through-hole mounting, designed for single-color indicator applications. This part operates at 1.8V with 2mA current consumption and features a diffused lens with domed top for 50° viewing angle. The main part is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. Active equivalent models from Dialight provide direct functional replacement while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the Dialight 5611101050 is determined by strict equivalence across all electrical and mechanical parameters. The allowed substitution criteria are:

• Color: Red (635nm peak wavelength)
• Configuration: Single LED
• Current: 2mA
• Voltage: 1.8V
• Millicandela: 2mcd
• Viewing Angle: 50°
• Lens Type: Diffused
• Lens Style: Round with Domed Top
• Lens Size: 5mm, T-1 3/4
• Mounting: Through Hole

All substitute parts listed meet these exact specifications. Substitutes differ only in product status (active vs. obsolete), packaging format (tape and reel vs. bulk), and RoHS compliance level.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts provide direct functional equivalence to the Dialight 5611101050. Selection should be based on the following factors:

Product Status: The original part 5611101050 is obsolete. All substitute parts (5501104F, 5611101050F, 5611101100F) are active products with ongoing manufacturer support and availability.

RoHS Compliance: The original part is RoHS non-compliant. All substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Series Continuity: Parts 5611101050F and 5611101100F maintain the 561 series designation, providing direct series-level compatibility. Part 5501104F belongs to the 550 series but maintains identical electrical and mechanical specifications.

Packaging: All substitutes are supplied in bulk packaging. If tape and reel packaging is required, consult with the manufacturer regarding availability of equivalent parts in alternative packaging formats.

Frequently Asked Questions (FAQ)

Q: Can 5501104F be used as a direct replacement for 5611101050? A: Yes. The 5501104F meets all electrical and mechanical specifications of the original part. The difference in series designation (550 vs. 561) reflects manufacturing evolution but does not affect functional compatibility. Both parts are identical in color, wavelength, current, voltage, brightness, viewing angle, lens type, and mounting configuration.

Q: What is the difference between 5611101050F and 5611101100F? A: Both parts maintain the 561 series and are electrically and mechanically identical to the original 5611101050. The difference lies in the base product number suffix (050 vs. 100), which reflects internal Dialight product line organization. Both are active products with ROHS3 compliance and bulk packaging.

Q: Why is the original 5611101050 marked as obsolete? A: Product obsolescence reflects manufacturer discontinuation of the specific packaging or production variant. The active substitute parts provide equivalent functionality and are recommended for new designs and ongoing production.

Q: Are there any compatibility concerns when switching from 5611101050 to a substitute part? A: No. All substitute parts are pin-compatible, electrically equivalent, and mechanically identical. They can be used interchangeably in existing circuit board designs without modification to PCB layout, component footprint, or electrical schematic.

Q: Does RoHS3 compliance affect electrical performance? A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical characteristics. All parts deliver identical performance in terms of voltage, current, brightness, and optical properties.

Q: What packaging format should I specify for production orders? A: All active substitute parts are available in bulk packaging. Confirm packaging requirements with your supplier, as tape and reel formats may require special order or alternative part numbers.
