Dialight 5923131813F LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5923131813F is a dual-level LED circuit board indicator featuring integrated green and yellow LEDs in a 2 High configuration. This component is designed for surface mount, right-angle applications requiring simultaneous dual-color indication at 2V and 30mA operating parameters. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Active alternatives with identical electrical specifications are available from the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5923131813F is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage Rating: 2V
• Current: 30mA
• Configuration: 2 High (dual-level LED)
• Color: Green and Yellow (x 2)
• Mounting Type: Surface Mount, Right Angle
• Series: 592 (Dialight)

Allowable Variations:

• Lens Type: Diffused to Round with Domed Top (both provide optical indication)
• Millicandela Rating: Reduction from 8mcd/6.5mcd to 3mcd/2mcd (lower brightness acceptable for indicator applications)
• Wavelength - Peak: Minor shifts within green (570nm to 572nm) and yellow (586nm to 587nm) ranges
• Packaging: Bulk to Tape & Reel (TR) (does not affect component function)
• MSL Rating: Increase from 1 to 2 (more restrictive storage conditions)
• Product Status: Obsolete to Active (ensures supply continuity)

The substitute parts 5923131302F and 5923131313F maintain electrical compatibility while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Both 5923131302F and 5923131313F are electrically and mechanically compatible with the 5923131813F. Selection between these two substitutes depends on procurement and assembly requirements:

• 5923131302F (Bulk Packaging): Suitable for applications requiring flexible order quantities and manual assembly processes.
• 5923131313F (Tape & Reel Packaging): Recommended for high-volume production and automated pick-and-place assembly operations.

Compliance Considerations: The substitute parts 5923131302F and 5923131313F carry ROHS3 compliance certification, whereas the main part does not specify this status. Both substitutes maintain REACH Unaffected and EAR99 ECCN classifications consistent with the original part.

Brightness Differential: The substitute parts operate at reduced millicandela ratings (3mcd/2mcd versus 8mcd/6.5mcd). This reduction is acceptable for circuit board indicator applications where visual confirmation rather than high-intensity illumination is the primary function. Verify that the reduced brightness meets the specific visibility requirements of the target application.

Optical Characteristics: The transition from diffused lens to round with domed top lens represents a change in light distribution pattern. Both lens types are suitable for indicator applications; however, the domed top design may provide slightly different viewing characteristics. Confirm that the optical properties align with the intended mounting orientation and viewing geometry.

Frequently Asked Questions (FAQ)

Q: Can 5923131302F and 5923131313F be used interchangeably with 5923131813F? A: Yes. Both substitute parts maintain identical electrical specifications (2V, 30mA, 2 High configuration, green/yellow colors) and mounting characteristics (surface mount, right angle). The primary differences are packaging format and optical lens design, neither of which affects electrical compatibility.

Q: What is the difference between the two substitute parts? A: 5923131302F is supplied in bulk packaging, while 5923131313F is supplied in Tape & Reel format on a 13-inch reel. Both parts are electrically and mechanically identical. Selection depends on assembly process requirements and order quantity needs.

Q: Why is the millicandela rating lower on the substitute parts? A: The substitute parts (3mcd/2mcd) provide reduced brightness compared to the original (8mcd/6.5mcd). For circuit board indicator applications, this reduction is functionally acceptable as the primary purpose is status indication rather than high-intensity illumination. Verify that the reduced brightness meets your specific application requirements.

Q: Are there any compliance differences between the main part and substitutes? A: The substitute parts carry ROHS3 compliance certification, while the main part does not specify this status. All three parts maintain REACH Unaffected and EAR99 ECCN classifications. If ROHS3 compliance is a requirement, the substitute parts provide this assurance.

Q: What is the impact of the lens design change from diffused to round with domed top? A: Both lens types are suitable for indicator applications. The diffused lens provides broader light scatter, while the domed top lens provides more focused light distribution. The choice depends on the specific viewing geometry and mounting orientation of your application. Both designs maintain adequate visibility for circuit board indicator functions.

Q: How does the MSL rating change affect storage and handling? A: The main part has MSL 1 (unlimited shelf life), while substitutes have MSL 2 (1-year shelf life). MSL 2 requires controlled storage conditions (≤30°C, ≤60% RH) and limits storage duration to one year from the date of manufacture. Ensure proper storage protocols are implemented for the substitute parts.

Q: Which substitute part should I select for automated assembly? A: 5923131313F in Tape & Reel packaging is optimized for automated pick-and-place assembly operations. This format provides consistent component spacing and orientation for high-volume production environments.

Q: Which substitute part should I select for manual assembly or low-volume production? A: 5923131302F in bulk packaging is suitable for manual assembly processes and applications with lower volume requirements, offering greater flexibility in order quantities.
