Dialight 5615501080 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5615501080 is a 5mm red LED circuit board indicator designed for through-hole mounting applications. This part operates at 2.2V with a 20mA forward current and delivers 125 millicandela brightness with a 24° viewing angle. The component features a clear lens with round domed top construction in the T-1 3/4 form factor.

The 5615501080 carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5615501080 is determined by strict alignment across the following critical parameters: color (red), wavelength peak (635nm), forward current (20mA), millicandela rating (125mcd), viewing angle (24°), lens type (clear), lens style (round with domed top), lens size (5mm T-1 3/4), forward voltage (2.2V), mounting type (through hole), and moisture sensitivity level (1 - Unlimited).

The substitute parts identified below maintain full electrical and mechanical compatibility with the original 5615501080 specification. All substitutes are manufactured by Dialight and share identical optical and electrical performance characteristics. The primary distinction among substitutes lies in product status (active versus obsolete) and RoHS compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain full electrical and mechanical compatibility with the 5615501080. Selection among substitutes should prioritize active product status and RoHS compliance requirements.

5615501100F and 5505504F are preferred substitutes. Both parts carry active product status and ROHS3 compliance certification. The 5615501100F remains within the original 561 series, while the 5505504F represents the 550 series equivalent. Both deliver identical optical and electrical performance.

5615501080F is an active-status variant within the 561 series with ROHS3 compliance. Lens style and lens size specifications are not provided for this part number variant, which may require verification against specific mechanical mounting requirements.

5505505010F is an active-status substitute with ROHS3 compliance within the 550 series. This part maintains full electrical and optical compatibility and is suitable for applications where series designation is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the 5615501080 be directly replaced with any of these substitute parts?

A: Yes. All four substitute parts maintain identical electrical characteristics (2.2V forward voltage, 20mA forward current), optical output (125mcd at 635nm peak wavelength, 24° viewing angle), and through-hole mounting configuration. Direct pin-for-pin substitution is supported.

Q: What is the difference between the 561 series and 550 series substitutes?

A: Both series are manufactured by Dialight and deliver identical electrical and optical performance for this application. The series designation reflects internal product line organization. Selection between series is not constrained by technical compatibility.

Q: Why do some substitute parts show incomplete lens specifications?

A: The 5615501080F does not include explicit lens style or lens size data in the provided specifications. However, this part maintains all critical electrical and optical parameters. Mechanical fit verification against specific PCB mounting requirements is recommended when lens geometry is critical to the application.

Q: Are all substitutes RoHS compliant?

A: The original 5615501080 is RoHS non-compliant. All four substitutes carry ROHS3 compliance certification. If RoHS compliance is required for your application, any of the four substitutes satisfy this requirement. If legacy RoHS non-compliant components are specifically required, the original 5615501080 remains the only option.

Q: What is the significance of the "F" suffix in part numbers?

A: The "F" suffix indicates bulk packaging format. All substitute parts with the "F" designation are supplied in bulk packaging, whereas the original 5615501080 carries a different packaging designation. Packaging format does not affect electrical or optical performance.

Q: Which substitute offers the best long-term availability?

A: All four substitutes carry active product status, indicating ongoing manufacturing and distribution. The 5615501100F and 5505504F represent the most established alternatives within their respective series lines.
