Dialight 5510307 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5510307 is a 3mm yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This part operates at 2.1V with a 10mA current rating and delivers 6.3mcd luminous intensity at a 45° viewing angle. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Active alternatives from Dialight and compatible manufacturers provide functional equivalency while maintaining compliance with current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5510307 is determined by strict electrical and mechanical compatibility across the following parameters:

Primary Substitution Criteria (Direct Equivalents):

• Color: Yellow
• Wavelength - Peak: 585nm
• Configuration: Single
• Current Rating: 10mA
• Voltage Rating: 2.1V
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle
• Viewing Angle: 45°

Direct Dialight Substitutes (5510302803F, 5510303F, 5510307010F, 5510307F, 5510311F) maintain all primary electrical parameters and mechanical form factors. These parts are manufactured by Dialight within the 551 series and are classified as active products with current RoHS3 compliance.

Similar Cross-Manufacturer Substitutes (H101CYD from Bivar Inc., WP934EW/YD from Kingbright) provide functional equivalency in yellow LED circuit board indicator applications. These parts share the same lens size (3mm, T-1), mounting configuration (through-hole), and color specification. However, they exhibit variations in current rating, voltage rating, millicandela output, and viewing angle that must be evaluated against specific circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

Preferred Direct Substitutes (Dialight 551 Series):

The Dialight parts 5510307F, 5510311F, 5510307010F, 5510302803F, and 5510303F are the primary substitution options. All five parts are active products with ROHS3 compliance and maintain the complete electrical and mechanical specification set of the obsolete 5510307. These parts are manufactured by the original equipment supplier and carry identical regulatory certifications (REACH Unaffected, EAR99 ECCN classification). Selection among these five Dialight alternatives should be based on packaging requirements and current inventory availability.

Cross-Manufacturer Alternatives:

The Bivar Inc. H101CYD and Kingbright WP934EW/YD provide functional yellow LED circuit board indicator solutions with the same 3mm T-1 form factor and through-hole mounting configuration. These parts are suitable for applications where the higher current ratings (20mA for H101CYD, 30mA for WP934EW/YD) and increased luminous intensity (20mcd and 15mcd respectively) are compatible with circuit design parameters. Both cross-manufacturer options maintain ROHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can I directly replace Dialight 5510307 with any of the Dialight 551 series substitutes?

A: Yes. The parts 5510307F, 5510311F, 5510307010F, 5510302803F, and 5510303F maintain identical electrical ratings (2.1V, 10mA), color specification (yellow, 585nm peak wavelength), and mechanical form factor (3mm T-1 through-hole right-angle mount). All are active products with current RoHS3 compliance.

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

A: The Dialight 551 series substitutes maintain the exact 10mA current rating and 6.3mcd luminous intensity of the original 5510307. The Bivar H101CYD operates at 20mA with 20mcd output, while the Kingbright WP934EW/YD operates at 30mA with 15mcd output. These differences require circuit design evaluation to ensure compatibility with existing current-limiting resistor networks and brightness requirements.

Q: Are there mounting differences between the Dialight substitutes and cross-manufacturer options?

A: The Dialight 551 series and Kingbright WP934EW/YD all feature through-hole right-angle mounting. The Bivar H101CYD features through-hole mounting without the right-angle specification. PCB layout compatibility must be confirmed for the Bivar option.

Q: Do all substitute parts meet the same regulatory requirements as the original 5510307?

A: All substitute parts listed are ROHS3 compliant and carry REACH Unaffected status. The original 5510307 RoHS status is not specified in available documentation. All parts share the same ECCN classification (EAR99) and HTSUS code (8541.41.0000).

Q: What packaging options are available for these substitutes?

A: The Dialight 551 series substitutes are available in bulk packaging. The Bivar H101CYD is supplied in tray packaging. The Kingbright WP934EW/YD is supplied in bulk packaging. Packaging selection should align with procurement and assembly process requirements.
