Dialight 5501107 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5501107 is a 5mm red LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a diffused lens with domed top, operating at 1.8V with 2mA current consumption and 2mcd brightness output. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. Active equivalent models from Dialight and cross-manufacturer alternatives are available to support design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5501107 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Configuration: Single
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole, Right Angle
• Lens Style: Round with Domed Top
• Lens Type: Diffused

Secondary Compatibility Parameters:

• Voltage Rating: 1.8V nominal
• Current: 2mA nominal
• Millicandela Rating: 2mcd nominal
• Viewing Angle: 50°

Substitute Categories:

Direct Equivalents (Dialight Series 550): Parts 5501105F and 5501107F maintain identical electrical specifications (1.8V, 2mA, 2mcd), mechanical form factor (5mm T-1 3/4 through-hole right-angle), and optical characteristics (50° viewing angle, diffused lens). Both are active products with ROHS3 compliance and bulk packaging availability.

Similar Alternative (Cross-Manufacturer): Part SSF-LXH100LID-01 from Lumex Opto/Components Inc. shares the same mechanical mounting configuration and lens form factor but operates at 2V with 20mA current consumption. This part functions as a substitute where circuit design accommodates the higher voltage and current requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

Parts 5501105F and 5501107F are the primary substitutes for the obsolete 5501107. Both maintain identical electrical and optical specifications, ensuring drop-in compatibility in existing circuit designs. Both parts carry active product status and ROHS3 compliance certification, supporting regulatory requirements for new production. Bulk packaging availability ensures supply chain continuity.

For Circuit Design Modifications:

The Lumex SSF-LXH100LID-01 serves as an alternative where circuit topology permits voltage and current adjustments. This part operates at 2V with 20mA consumption, requiring corresponding modifications to current-limiting resistor values and power supply considerations. Selection of this part is appropriate only when the host circuit design can accommodate the increased power requirements and voltage specification.

Compliance Considerations:

All active substitute parts maintain ROHS3 compliance and REACH unaffected status, aligning with current regulatory frameworks. The obsolete status of the original 5501107 necessitates transition to an active equivalent for new production and long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can 5501105F and 5501107F be used interchangeably with 5501107?

A: Yes. Both parts maintain identical voltage (1.8V), current (2mA), brightness (2mcd), viewing angle (50°), and mechanical form factor (5mm T-1 3/4 through-hole right-angle). Both are active products with ROHS3 compliance, making them direct functional equivalents.

Q: What are the key differences between the Dialight direct equivalents and the Lumex alternative?

A: The Dialight parts (5501105F, 5501107F) match the original 5501107 specifications exactly. The Lumex SSF-LXH100LID-01 operates at higher voltage (2V vs. 1.8V) and current (20mA vs. 2mA), requiring circuit modifications. Use the Lumex part only when your design can accommodate these electrical differences.

Q: Does the Lumex SSF-LXH100LID-01 have the same brightness as the original part?

A: The Lumex part does not specify millicandela rating or viewing angle in the provided data. While it shares the same 5mm T-1 3/4 form factor and diffused lens style, brightness characteristics cannot be confirmed as equivalent without additional technical documentation.

Q: Are all substitute parts available in bulk packaging?

A: Yes. Both Dialight direct equivalents (5501105F, 5501107F) and the Lumex alternative (SSF-LXH100LID-01) are available in bulk packaging, supporting production volume requirements.

Q: What is the MSL rating for these parts?

A: All parts, including the original 5501107 and all substitutes, carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.
