Dialight 5611101080 LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5611101080 is a 5mm red LED circuit board indicator designed for through-hole mounting applications. This component features a single red diffused lens with a domed top, operating at 1.8V with a 2mA current rating and 2mcd millicandela output. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives from the same manufacturer provide identical electrical and mechanical specifications with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5611101080 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

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

All qualified substitutes maintain identical electrical performance characteristics and physical form factors. The primary distinction between the main part and substitutes is product status and RoHS compliance level. Substitute parts 5611101100F, 5611101050F, and 5611101080F are classified as active products with ROHS3 compliance, while 5501104F represents an alternative series designation within the same electrical specification range.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (5611101100F, 5611101050F, 5611101080F, and 5501104F) provide direct functional equivalence to the obsolete 5611101080. Selection among these alternatives should be based on the following factors:

Product Status Consideration: Parts 5611101100F, 5611101050F, and 5611101080F are classified as active products with current manufacturing support and availability. Part 5501104F is also active but represents a different series designation (550 versus 561).

Compliance Status: All substitute parts carry ROHS3 compliance certification, whereas the original 5611101080 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements.

Inventory Availability: Substitute parts demonstrate higher stock levels (1,028 to 2,492 units) compared to the original part (888 units), supporting supply chain continuity.

Packaging: All substitutes are supplied in bulk packaging format, consistent with production requirements.

Frequently Asked Questions (FAQ)

Q: Can 5611101100F, 5611101050F, 5611101080F, and 5501104F be used interchangeably with 5611101080?

A: Yes. All four parts maintain identical electrical specifications (1.8V, 2mA, 2mcd, 635nm red wavelength) and mechanical form factors (5mm through-hole, diffused lens, 50° viewing angle). They are direct functional equivalents.

Q: What is the primary difference between the original part and the substitutes?

A: The original 5611101080 is classified as obsolete and RoHS non-compliant. All substitute parts are active products with ROHS3 compliance certification, ensuring regulatory alignment for new designs and ongoing production.

Q: Are there differences between the 561 series substitutes (5611101100F, 5611101050F, 5611101080F) and the 550 series substitute (5501104F)?

A: All parts share identical electrical and optical specifications. The series designation reflects internal Dialight product categorization but does not affect functional performance or compatibility.

Q: What packaging format are the substitute parts supplied in?

A: All substitute parts are supplied in bulk packaging, suitable for production assembly operations.

Q: Do the substitute parts have the same moisture sensitivity rating?

A: Yes. All parts, including the original 5611101080, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.
