LTL-2655HR LED Indicator Bar Equivalent & Substitute Parts

Part Overview

The LTL-2655HR is an active red LED circuit board indicator bar manufactured by Lite-On Inc. This through-hole mounted component features a diffused lens with square flat-top design and 8.89mm form factor. The part is designed for standard indicator applications requiring a 2V, 100mA red LED with 635nm peak wavelength output. Substitute parts are identified to address inventory availability, lead time requirements, or specific application performance needs while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

The KB2655EW from Kingbright is identified as a manufacturer-recommended substitute for the LTL-2655HR. Substitution compatibility is determined by the following critical parameters:

• Lens size: 8.89mm (identical)
• Lens style: Square with Flat Top (identical)
• Configuration: Bar - Single, DIP (identical)
• Mounting type: Through Hole (identical)
• Color: Red (identical)
• Voltage rating: 2V (identical)
• RoHS compliance: ROHS3 Compliant (identical)

The KB2655EW maintains mechanical and electrical compatibility through matching form factor, mounting interface, and voltage specification. Differences in current rating (30mA vs. 100mA), millicandela output (40mcd vs. 8mcd), and wavelength (625nm vs. 635nm) represent performance variations within the red LED indicator category and do not prevent functional substitution in standard indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LTL-2655HR and KB2655EW are active products with ROHS3 compliance and unlimited moisture sensitivity ratings, making either suitable for standard production applications. The KB2655EW offers higher luminous intensity (40mcd vs. 8mcd) at reduced current consumption (30mA vs. 100mA), which may provide advantages in power-constrained designs or applications requiring increased visibility. The LTL-2655HR operates at higher current and lower brightness, suitable for applications with specific brightness requirements or existing circuit designs optimized for 100mA operation. Both parts maintain identical mechanical compatibility and voltage specifications, enabling direct substitution at the board level without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can KB2655EW be used as a direct replacement for LTL-2655HR without PCB modification?

A: Yes. Both parts share identical lens size (8.89mm), lens style (square with flat top), configuration (bar single DIP), mounting type (through hole), and voltage rating (2V). No PCB layout changes are required for mechanical and electrical compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are current rating (LTL-2655HR: 100mA; KB2655EW: 30mA), millicandela output (LTL-2655HR: 8mcd; KB2655EW: 40mcd), and wavelength (LTL-2655HR: 635nm; KB2655EW: 625nm). These represent performance variations within the red LED indicator category.

Q: Does the lower current requirement of KB2655EW affect circuit design?

A: The KB2655EW operates at 30mA versus the LTL-2655HR at 100mA. Existing circuits designed for 100mA operation will function with the KB2655EW, though current-limiting resistor values may require adjustment to optimize brightness and power consumption for the specific application.

Q: Are both parts RoHS compliant?

A: Yes. Both LTL-2655HR and KB2655EW are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity), meeting standard environmental and regulatory requirements for production applications.

Q: What packaging formats are available?

A: LTL-2655HR packaging is not specified in available data. KB2655EW is supplied in tube packaging. Confirm packaging requirements with your procurement or supply chain team.
