Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTP-537G is determined by the following critical parameters:

• Display Configuration: 16-segment alphanumeric format with single character capacity
• Package Compatibility: 18-DIP (0.500", 12.70mm) footprint for direct PCB mounting
• Mechanical Fit: Identical physical dimensions (25.00mm x 16.00mm x 9.50mm) and character size (0.50")
• Electrical Interface: Common cathode configuration with 20mA test current
• Optical Properties: Green color with 565nm peak wavelength
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The PSC05-12GWA from Kingbright meets all substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the LTP-537G and PSC05-12GWA are active production parts with ROHS3 compliance and MSL 1 rating. Selection between these parts is based on application-specific requirements:

The LTP-537G operates at a typical forward voltage of 2.1V with a maximum power dissipation of 75mW and brightness of 2.2mcd.

The PSC05-12GWA operates at a typical forward voltage of 2.2V with a maximum power dissipation of 62.5mW and brightness of 10mcd.

Both parts share identical mechanical and electrical interface specifications, including package footprint, pin configuration, and test current. The PSC05-12GWA offers higher brightness output and lower power dissipation, while maintaining full compatibility with the LTP-537G pinout and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can PSC05-12GWA replace LTP-537G in existing designs?

A: Yes. Both parts feature identical 18-DIP package footprints, common cathode configuration, 20mA test current, and 565nm peak wavelength. Pin-for-pin compatibility is maintained.

Q: What are the differences in electrical performance?

A: The PSC05-12GWA has a forward voltage of 2.2V compared to 2.1V for the LTP-537G. The PSC05-12GWA provides 10mcd brightness versus 2.2mcd for the LTP-537G, and dissipates 62.5mW maximum versus 75mW for the LTP-537G.

Q: Are both parts RoHS compliant?

A: Yes. Both the LTP-537G and PSC05-12GWA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
