Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTP-3784JD-01 is determined by the following critical parameters:

• Display Configuration: 2-character, 14-segment alphanumeric format with common cathode topology
• Physical Package: 18-DIP (0.600", 15.24mm) form factor with matching dimensional envelope
• Electrical Compatibility: Forward voltage within acceptable operating range, test current at 20mA
• Character Size: 0.54" (13.72mm) alphanumeric digit height
• Color Specification: Red wavelength in the 645–650nm range
• Compliance: ROHS3 compliance and EAR99 classification

The substitute part PDC54-11SURKWA from Kingbright meets these criteria through identical package geometry, matching character count and display type, common cathode configuration, and compatible electrical parameters within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the LTP-3784JD-01 and PDC54-11SURKWA maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The PDC54-11SURKWA operates at a lower forward voltage (1.95V versus 2.1V) while maintaining identical test current specifications, resulting in reduced power dissipation per segment. Dimensional tolerances between the two units remain within 0.02" across all axes, ensuring mechanical interchangeability within standard PCB footprint tolerances. Both components carry EAR99 export classification and fall under the same HTSUS commodity code, supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can PDC54-11SURKWA replace LTP-3784JD-01 in existing designs?

A: Yes. Both components share identical 18-DIP package geometry, 2-character 14-segment alphanumeric display configuration, common cathode topology, and 20mA test current specification. Dimensional differences are negligible (less than 0.02" variance), and both operate within compatible voltage ranges for standard LED display applications.

Q: What are the electrical differences between these parts?

A: The PDC54-11SURKWA operates at 1.95V forward voltage compared to the LTP-3784JD-01 at 2.1V. This 0.15V difference reduces power dissipation from 70mW to 75mW maximum. The PDC54-11SURKWA exhibits higher luminous intensity (68mcd versus 0.52mcd), while wavelength peaks differ slightly (645nm versus 650nm), both within the red spectrum range.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry EAR99 export classification. The LTP-3784JD-01 specifies Moisture Sensitivity Level (MSL) 1 (Unlimited), while the PDC54-11SURKWA lists MSL as Not Applicable. Both components fall under HTSUS code 8541.41.0000.

Q: What is the physical footprint compatibility?

A: Both components use 18-DIP (0.600", 15.24mm) package format with matching pin spacing. Overall dimensions are nearly identical: LTP-3784JD-01 measures 0.833" H x 0.989" W x 0.307" D, while PDC54-11SURKWA measures 0.835" H x 0.992" W x 0.307" D. These tolerances are within standard PCB design margins.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The PDC54-11SURKWA offers higher brightness (68mcd) and lower forward voltage operation, making it suitable for battery-powered or low-power applications. The LTP-3784JD-01 maintains established design history with Lite-On manufacturing. Both are Active products with equivalent compliance profiles.
