LTP-2088AY Equivalent & Substitute Parts

Part Overview

The LTP-2088AY is an 8 x 8 dot matrix display module manufactured by LITEON, featuring a common cathode row and common anode column configuration with yellow LED output. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design requirements and production continuity. The module operates at a forward voltage of 2.1V with a brightness rating of 4.8mcd and physical dimensions of 2.37" L x 2.37" W x 0.36" H (60.20mm x 60.20mm x 9.10mm).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTP-2088AY is based on the following critical parameters that must remain consistent:

• Configuration: 8 x 8 matrix layout
• Color: Yellow LED output
• Internal Connection: Common Cathode Row, Common Anode Column topology
• Physical Dimensions: 2.37" L x 2.37" W (60.20mm x 60.20mm) footprint compatibility
• Forward Voltage Range: Nominal 2.0V to 2.1V operation
• Moisture Sensitivity Level: MSL 1 or equivalent

The GMA24Y88 from QT Brightek meets all substitution criteria within these allowed parameters.

Parameter Comparison

Engineering Selection Recommendations

The GMA24Y88 is the qualified substitute for the LTP-2088AY based on the following factors:

• Product Status: The GMA24Y88 is active and currently in production, whereas the LTP-2088AY is obsolete. This ensures long-term availability and supply chain continuity.
• Compliance: The GMA24Y88 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components.
• Electrical Compatibility: Both parts operate within compatible forward voltage ranges (2.0V vs. 2.1V) and share identical matrix configuration and internal connection topology.
• Physical Compatibility: Dimensions are equivalent within manufacturing tolerance (9.10mm vs. 9.20mm height difference is negligible for PCB mounting).
• Brightness Enhancement: The GMA24Y88 provides significantly higher brightness (90mcd vs. 4.8mcd), which may improve display visibility in applications without requiring circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the GMA24Y88 be used as a direct replacement for the LTP-2088AY?

A: Yes. Both parts share identical 8 x 8 configuration, common cathode row/common anode column topology, yellow color, and equivalent physical dimensions. Forward voltage is within compatible operating range (2.0V vs. 2.1V).

Q: What is the significance of the brightness difference (4.8mcd vs. 90mcd)?

A: The GMA24Y88 provides higher luminous intensity. This does not prevent substitution but may alter display brightness characteristics. Circuit current-limiting resistors may require adjustment if brightness uniformity is critical to the application.

Q: Are there packaging differences between these parts?

A: The LTP-2088AY packaging is specified as "-" (not detailed). The GMA24Y88 is supplied in Bulk packaging. Both parts maintain the same physical footprint for PCB mounting.

Q: Does the 0.1mm height difference (9.10mm vs. 9.20mm) affect compatibility?

A: No. This difference is within standard manufacturing tolerance and does not impact PCB assembly or mechanical fit.

Q: What compliance advantages does the GMA24Y88 offer?

A: The GMA24Y88 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The LTP-2088AY compliance status is not specified.

Q: Is the GMA24Y88 available in sufficient quantity?

A: Yes. Current inventory shows 1134 pieces in stock as new original components.
