Dialight 5510604F LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5510604F is an LED Circuit Board Indicator (CBI) designed for 3mm through-hole right-angle mounting applications. This single green diffused LED operates at 5V with a 10mA current rating and delivers 19 millicandela output at a 565nm peak wavelength. The component features a round domed top lens with a 60° viewing angle, making it suitable for status indication and visual feedback applications on circuit boards.

The 5510604F maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified to address inventory availability, supply chain continuity, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5510604F is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

• Color: Green
• Wavelength - Peak: 565nm
• Configuration: Single
• Current Rating: 10mA
• Millicandela Rating: 19mcd
• Viewing Angle: 60°
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Voltage Rating: 5V
• Mounting Type: Through Hole, Right Angle
• Series: 551
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The identified substitute parts 5510607F and 5510609F meet all these criteria and are therefore electrically and mechanically interchangeable with the 5510604F in circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5510604F, 5510607F, and 5510609F—are Active status components with identical electrical and mechanical specifications. Each maintains full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on inventory availability and supply chain requirements. The 5510609F offers the highest current inventory level at 1745 pieces, followed by 5510607F at 1524 pieces, and 5510604F at 1026 pieces. All parts are packaged in bulk format and are suitable for direct substitution in through-hole right-angle mounting applications requiring 5V green LED indicators with 19mcd output.

Frequently Asked Questions (FAQ)

Q: Can 5510607F and 5510609F be used interchangeably with 5510604F?

A: Yes. Both substitute parts are electrically and mechanically identical to the 5510604F across all specified parameters, including voltage rating, current consumption, light output, viewing angle, lens characteristics, and mounting configuration.

Q: What determines substitution eligibility for these LED indicators?

A: Substitution is based on exact equivalence of electrical parameters (voltage, current, wavelength, luminous intensity) and mechanical parameters (lens type, lens size, mounting style, form factor). All three parts meet these criteria.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All three parts carry identical RoHS3 compliance status, REACH unaffected classification, and Moisture Sensitivity Level 1 rating.

Q: Does packaging format differ between these parts?

A: All three parts are supplied in bulk packaging format with no packaging differences.

Q: Which part should be selected for new designs?

A: Any of the three parts is suitable for new designs. Selection may be based on current inventory availability or supplier preference, as all parts are functionally equivalent.
