Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5510607 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Color: Green
• Wavelength - Peak: 565nm nominal (568nm acceptable within LED manufacturing tolerance)
• Configuration: Single
• Voltage Rating: 5V
• Mounting Type: Through Hole, Right Angle
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top

Secondary Compatibility Parameters:

• Current Rating: 10mA to 17.5mA (within typical circuit design margins)
• Millicandela Rating: 19mcd to 80mcd (brightness variation acceptable based on application requirements)
• Viewing Angle: 40° to 60° (application-dependent)
• Lens Size: 2.90mm to 3.00mm (mechanical fit consideration)

Substitutes are grouped into two categories: Direct manufacturer variants and cross-manufacturer equivalents. All identified substitutes maintain the core electrical and mechanical specifications required for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Dialight 5510607F is the primary direct substitute. This part maintains identical electrical specifications (10mA, 19mcd, 60° viewing angle) and is manufactured by the original supplier. Product status is Active with RoHS3 compliance, ensuring long-term availability and regulatory alignment. Mechanical compatibility is confirmed through matching lens configuration and mounting type.

Lumex Opto/Components Inc. SSF-LXH103GD-5V provides an alternative cross-manufacturer option. This part operates at 12mA with increased brightness (80mcd) and narrower viewing angle (8°). Selection of this substitute requires circuit design review to accommodate the higher current draw and modified optical characteristics. Product status is Active with RoHS3 compliance.

Kingbright WP934EW/GD5V offers a secondary cross-manufacturer alternative with slightly reduced lens diameter (2.90mm versus 3.00mm). Current rating is elevated to 17.5mA with moderate brightness increase (25mcd). Wavelength peak is 568nm, within acceptable LED manufacturing tolerance. Product status is Active with RoHS3 compliance. Mechanical fit verification is required due to lens size variance.

All substitute parts maintain compliance with REACH regulations, EAR99 export classification, and HTSUS tariff code 8541.41.0000.

Frequently Asked Questions (FAQ)

Q: Can Dialight 5510607F be used as a direct replacement for the obsolete 5510607?

A: Yes. The 5510607F is a direct manufacturer equivalent with identical electrical ratings (5V, 10mA, 19mcd), matching wavelength (565nm), and equivalent optical characteristics (60° viewing angle, diffused tinted lens, round domed top). Both parts are manufactured by Dialight and share the same series designation (551). The primary difference is product status: 5510607F is Active, ensuring continued availability.

Q: What are the key differences between the Dialight and cross-manufacturer substitutes?

A: The Lumex SSF-LXH103GD-5V operates at 12mA (versus 10mA) with significantly higher brightness (80mcd versus 19mcd) and a narrower viewing angle (8° versus 60°). The Kingbright WP934EW/GD5V operates at 17.5mA with moderate brightness increase (25mcd) and a slightly smaller lens diameter (2.90mm versus 3.00mm). Both cross-manufacturer options require circuit design evaluation to confirm compatibility with existing current-limiting resistor values and optical requirements.

Q: Are there mechanical compatibility concerns with the substitute parts?

A: The Dialight 5510607F and Lumex SSF-LXH103GD-5V maintain the same 3mm lens diameter specification and Through Hole, Right Angle mounting configuration. The Kingbright WP934EW/GD5V has a 2.90mm lens diameter, which may require mechanical fit verification in applications with tight tolerance requirements. All three substitutes use identical mounting type and lens style (round with domed top).

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All substitute parts are REACH Unaffected, classified as EAR99 for export purposes, and assigned HTSUS code 8541.41.0000. The Dialight 5510607F and both cross-manufacturer substitutes are RoHS3 compliant. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: What is the impact of different current ratings on circuit design?

A: The original 5510607 and its direct substitute 5510607F are rated at 10mA. The Lumex SSF-LXH103GD-5V requires 12mA, and the Kingbright WP934EW/GD5V requires 17.5mA. If substituting with higher-current parts, the series current-limiting resistor must be recalculated to maintain proper LED operation and prevent exceeding maximum ratings. The voltage rating remains 5V across all parts.

Q: Which substitute is recommended for new designs?

A: For new designs requiring a green 5V LED circuit board indicator with Through Hole, Right Angle mounting, the Dialight 5510607F is the preferred choice due to identical electrical specifications and direct manufacturer equivalence. Cross-manufacturer substitutes (Lumex and Kingbright) are suitable alternatives if specific optical or current characteristics align with application requirements.
