Dialight 5660307 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5660307 is a yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a 5mm round lens with domed top, operating at 2.1V with 20mA current consumption and 4.6mcd brightness output. The part is currently obsolete, making identification of suitable substitutes essential for ongoing production support and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

The Dialight 5660307F qualifies as a direct substitute based on the following critical parameters that remain constant across both parts:

• Color: Yellow (583nm peak wavelength)
• Configuration: Single LED
• Current Rating: 20mA
• Brightness: 4.6mcd
• Viewing Angle: 110°
• Lens Type: Diffused, Tinted
• Voltage Rating: 2.1V
• Mounting Type: Through Hole, Right Angle

The primary difference between the main part and substitute is the lens geometry: the 5660307 features a round lens with domed top (5mm, T-1 3/4), while the 5660307F uses a rectangle lens with flat top. Both maintain identical electrical performance and optical characteristics. The 5660307F is currently in active production status, providing ongoing availability for applications requiring these electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5660307F is the designated substitute for the obsolete 5660307. Selection of the 5660307F is supported by:

• Identical electrical specifications (2.1V, 20mA, 4.6mcd)
• Matching optical characteristics (yellow, 583nm, 110° viewing angle, diffused tinted lens)
• Same mounting configuration (through-hole, right-angle)
• Active production status ensuring supply continuity
• Enhanced RoHS3 compliance compared to the non-compliant main part

The lens geometry difference (round domed versus rectangular flat) represents a mechanical variation that may affect physical fit within specific PCB cutouts or mechanical assemblies. Verification of mechanical compatibility with the target application's physical constraints is necessary prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the 5660307F be used as a direct replacement for the 5660307?

A: The 5660307F matches all electrical and optical specifications of the 5660307. However, the lens geometry differs: the 5660307 has a round domed lens while the 5660307F has a rectangular flat lens. Mechanical compatibility with the PCB mounting hole and surrounding assembly must be confirmed.

Q: What is the primary reason for substitution?

A: The 5660307 is obsolete. The 5660307F provides equivalent electrical performance with active production status and improved RoHS3 compliance.

Q: Are the brightness and color characteristics identical?

A: Yes. Both parts deliver 4.6mcd brightness at 583nm peak wavelength with identical 110° viewing angles and diffused tinted lens properties.

Q: What is the difference in lens design?

A: The 5660307 features a 5mm round lens with domed top. The 5660307F uses a 2mm × 5mm rectangular lens with flat top. Both maintain the same optical diffusion and tinting characteristics.

Q: Does the 5660307F offer better compliance?

A: Yes. The 5660307F is ROHS3 compliant, whereas the 5660307 is RoHS non-compliant. Both maintain REACH Unaffected status.

Q: What mounting considerations apply?

A: Both parts use through-hole, right-angle mounting. The rectangular lens geometry of the 5660307F may require PCB cutout modifications if the original design accommodated the round lens of the 5660307.
