LTP-747E Equivalent & Substitute Parts

Part Overview

The LTP-747E is a 5 x 7 dot matrix display module manufactured by Lite-On Inc., featuring a common cathode row and common anode column configuration with orange-red color output. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The module operates at 2V forward voltage with a 2mcd brightness rating and is housed in a compact 0.50" L x 0.70" W x 0.25" H form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTP-747E are qualified based on the following critical parameters:

• Configuration: 5 x 7 dot matrix layout
• Internal Connection: Common cathode row, common anode column topology
• Size / Dimension: Physical form factor 0.50" L x 0.70" W x 0.25" H
• Voltage - Forward (Vf): Operating voltage range compatible with 2V specification
• Moisture Sensitivity Level: MSL 1 classification

The LTP-747E has two qualified substitutes: the LTP-747KA (direct manufacturer equivalent from Lite-On Inc.) and the TA07-11EWA (manufacturer-recommended alternative from Kingbright). Both maintain identical mechanical dimensions, electrical configuration, and moisture sensitivity ratings. Variations in millicandela rating and forward voltage represent acceptable parameter ranges within the 5 x 7 dot matrix display category.

Parameter Comparison

Engineering Selection Recommendations

The LTP-747KA serves as the primary direct substitute for the LTP-747E, sharing identical manufacturer lineage and maintaining full compatibility across all critical electrical and mechanical parameters. Both components carry MSL 1 classification and identical ECCN/HTSUS codes. The LTP-747KA is currently in active production status with ROHS3 compliance certification.

The TA07-11EWA from Kingbright is the manufacturer-recommended alternative, offering active product status and ROHS3 compliance. This substitute maintains the same 5 x 7 configuration, common cathode/anode topology, and MSL 1 rating. The TA07-11EWA operates at 2V forward voltage matching the LTP-747E specification. Physical dimensions are within acceptable tolerance (12.70mm x 17.80mm versus 12.66mm x 17.74mm). The increased millicandela rating (8.2mcd versus 2mcd) represents enhanced brightness performance.

Selection between LTP-747KA and TA07-11EWA depends on color matching requirements (orange-red versus red) and brightness performance needs. Both substitutes are qualified for direct replacement in applications where the LTP-747E is specified.

Frequently Asked Questions (FAQ)

Q: Can the LTP-747KA directly replace the LTP-747E without circuit modifications?

A: Yes. The LTP-747KA maintains identical electrical configuration (common cathode row, common anode column), forward voltage (2.05V versus 2V), and physical dimensions. No circuit modifications are required.

Q: What is the primary difference between the LTP-747KA and TA07-11EWA substitutes?

A: The LTP-747KA is a direct Lite-On Inc. equivalent with orange-red color matching. The TA07-11EWA is a Kingbright alternative with red color output and higher brightness (8.2mcd versus 3.4mcd). Both maintain identical mechanical configuration and electrical topology.

Q: Are there color compatibility considerations when selecting between substitutes?

A: Yes. The LTP-747E and LTP-747KA both produce orange-red output. The TA07-11EWA produces red output. Applications requiring specific color matching should select the LTP-747KA. Applications where increased brightness is acceptable may use the TA07-11EWA.

Q: Do both substitutes meet current compliance standards?

A: Yes. Both the LTP-747KA and TA07-11EWA carry ROHS3 compliance certification and MSL 1 moisture sensitivity rating. Both are classified under identical ECCN (EAR99) and HTSUS (8541.41.0000) codes.

Q: What are the physical dimension tolerances between substitutes?

A: The LTP-747E and LTP-747KA share identical dimensions (12.66mm x 17.74mm x 6.30mm). The TA07-11EWA dimensions are 12.70mm x 17.80mm x 6.30mm, representing a 0.04mm and 0.06mm variance in length and width respectively. These tolerances are within standard PCB mounting specifications for this component category.

Q: Is the increased brightness of the TA07-11EWA (8.2mcd) a concern for existing designs?

A: The TA07-11EWA brightness increase is a performance enhancement. Existing designs using the LTP-747E (2mcd) will display increased brightness with the TA07-11EWA (8.2mcd). Circuit current limiting resistors may require adjustment if brightness control is critical to application performance.
