Dialight 5510601F LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5510601F is an active LED Circuit Board Indicator designed for through-hole, right-angle mounting applications. This single green diffused LED operates at 5V with a 10mA current rating and delivers 19 millicandela brightness output. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial circuit board applications. Substitute parts are identified to provide design flexibility when primary inventory is unavailable or when alternative mounting configurations are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5510601F are qualified based on strict electrical and mechanical parameter matching within the Dialight 551 series. All substitute parts maintain identical specifications across the following critical parameters: green color output at 565nm peak wavelength, single configuration, 5V voltage rating, 10mA current draw, 19mcd brightness output, 60° viewing angle, diffused tinted lens type, round domed top lens style, 3mm T-1 lens size, through-hole right-angle mounting, ROHS3 compliance, and MSL 1 rating.

The identified substitutes are:

• 5510607F: Dialight 551 series green LED with matching electrical and optical specifications
• 5510609F: Dialight 551 series green LED with matching electrical and optical specifications

All three parts (5510601F, 5510607F, 5510609F) are functionally equivalent for circuit board indicator applications requiring these exact parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5510601F, 5510607F, and 5510609F—are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and specific application requirements. The 5510607F and 5510609F maintain higher current stock levels (1524 and 1745 units respectively) compared to the 5510601F (728 units). All parts carry identical electrical ratings, optical characteristics, and environmental compliance certifications, ensuring direct functional interchangeability in circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can 5510607F or 5510609F be used as direct replacements for 5510601F? A: Yes. All three parts share identical electrical specifications (5V, 10mA), optical output (19mcd at 565nm), mechanical form factor (3mm T-1 through-hole right-angle), and compliance certifications (ROHS3, MSL 1). They are functionally equivalent for circuit board indicator applications.

Q: What are the differences between these three part numbers? A: The provided specifications indicate these parts are electrically and mechanically identical. Differences in part numbering reflect Dialight's internal product designation system.
