Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTP-2757AA is determined by the following critical parameters:

• Configuration Match: 5 x 7 dot matrix format
• Internal Connection Architecture: Common anode row, common cathode column topology
• Physical Footprint Compatibility: Dimensions within acceptable tolerance (1.50" L x 2.09" W, height ≤ 0.34")
• Color Availability: Green and red/orange-red LED options
• Forward Voltage Compatibility: Green ≤ 2.2V, Red/Orange-Red ≤ 2.0V
• Regulatory Compliance: ROHS3 compliant, MSL 1 rating

The TBC20-11EGWA from Kingbright meets all substitution criteria. It maintains identical configuration, connection architecture, and physical footprint compatibility. The part is currently in active production status, ensuring supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The TBC20-11EGWA is a direct functional substitute for the LTP-2757AA. Both components maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory requirements for equivalent component selection.

The TBC20-11EGWA is currently in active production status, providing supply chain continuity for applications requiring 5x7 dot matrix display modules with common anode row and common cathode column architecture. The substitute part delivers higher luminous intensity (15mcd green, 10mcd red) while maintaining compatible forward voltage specifications and identical physical footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TBC20-11EGWA replace the LTP-2757AA in existing designs without circuit modification?

A: Yes. Both components share identical internal connection architecture (common anode row, common cathode column), compatible forward voltage specifications, and matching physical footprints. No circuit redesign is required for direct substitution.

Q: What is the significance of the higher millicandela rating in the TBC20-11EGWA?

A: The TBC20-11EGWA delivers 15mcd green and 10mcd red compared to 4.8mcd for both colors in the LTP-2757AA. This represents increased luminous intensity. Applications requiring the original brightness specification should incorporate appropriate current-limiting resistor adjustments to maintain equivalent display brightness.

Q: Are there dimensional compatibility concerns between these two parts?

A: The physical footprints are compatible. The LTP-2757AA measures 0.34" H (8.60mm), while the TBC20-11EGWA measures 0.33" H (8.50mm). This 0.1mm height difference does not affect PCB mounting or mechanical assembly compatibility.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the LTP-2757AA and TBC20-11EGWA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Regulatory requirements are satisfied for either component selection.

Q: Why is the LTP-2757AA classified as obsolete?

A: The LTP-2757AA is no longer in active production. The TBC20-11EGWA from Kingbright is the recommended substitute, offering active production status and supply chain availability for ongoing applications.
