Dialight 5505312F LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505312F is a 5mm LED Circuit Board Indicator with yellow diffused lens and right-angle through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The original part operates at 60mA with a 34mcd brightness rating and features a round domed-top lens configuration in the 550 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5505312F is based on the following critical parameters that must remain consistent:

• Physical Form Factor: 5mm lens size (T-1 3/4), round domed-top diffused lens
• Mounting Configuration: Through-hole, right-angle orientation
• Color: Yellow wavelength emission
• Regulatory Compliance: ROHS3 and REACH status maintained
• Series Compatibility: Dialight 550 series

The Dialight 5502312F qualifies as a manufacturer-recommended substitute. While electrical characteristics differ (10mA vs. 60mA current, 6.3mcd vs. 34mcd brightness), the mechanical and optical properties remain compatible. The substitute maintains identical lens geometry, mounting style, and physical dimensions, enabling direct board-level replacement where circuit design accommodates the reduced current draw and brightness output.

Parameter Comparison

Engineering Selection Recommendations

The 5502312F is the manufacturer-recommended substitute for the obsolete 5505312F. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in production environments.

Selection of the 5502312F requires circuit-level evaluation of the reduced electrical specifications: 10mA operating current versus the original 60mA, and 6.3mcd brightness versus 34mcd. Applications requiring the original brightness output or current characteristics must conduct functional validation before implementation.

The active product status of the 5502312F provides supply chain stability and long-term availability compared to the obsolete 5505312F.

Frequently Asked Questions (FAQ)

Q: Can the 5502312F directly replace the 5505312F on existing circuit boards?

A: Physical and mechanical compatibility is confirmed. The 5mm T-1 3/4 lens size, round domed-top diffused configuration, and right-angle through-hole mounting are identical. Circuit design must accommodate the reduced current draw (10mA vs. 60mA) and lower brightness output (6.3mcd vs. 34mcd).

Q: What are the key differences between these parts?

A: The primary differences are electrical: the 5502312F operates at 10mA with 2.1V rating and produces 6.3mcd brightness, while the 5505312F operates at 60mA with 34mcd brightness. Optical and mechanical properties remain consistent.

Q: Why is the 5505312F obsolete?

A: The 5505312F is classified as obsolete by Dialight. The 5502312F represents the active product line continuation within the 550 series for yellow diffused 5mm right-angle LED indicators.

Q: Are there compliance differences between the parts?

A: Both parts maintain identical ROHS3 compliance and REACH unaffected status. No regulatory divergence exists between the original and substitute.

Q: What packaging is available for the 5502312F?

A: The 5502312F is supplied in bulk packaging configuration.
