LTS-6860Y Equivalent & Substitute Parts

Part Overview

The LTS-6860Y is a 0.56" yellow 7-segment LED display module manufactured by Lite-On Inc., configured as a single character common anode display in a 10-DIP package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates at 2.1V forward voltage with 20mA test current and delivers 2.4mcd brightness at a 585nm peak wavelength.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTS-6860Y is determined by the following mandatory parameters:

• Display Type: 7-Segment configuration
• Character Count: Single character
• Digit Size: 0.56" (14.22mm)
• Color: Yellow
• Common Pin: Common Anode
• Package: 10-DIP (0.600", 15.24mm)
• Voltage - Forward (Typ): 2.1V nominal
• Current - Test: 20mA
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in physical dimensions (height/width within tolerance), brightness (millicandela rating), wavelength, and power dissipation do not preclude substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

HDSP-511Y (Broadcom Limited) is the manufacturer-recommended substitute. This part maintains active product status with ROHS3 compliance and REACH unaffected certification. The forward voltage is 2.15V, within acceptable tolerance of the original 2.1V specification. Power dissipation is reduced to 52mW, and brightness is comparable at 2.6mcd.

HDSP-5701 (Broadcom Limited) is a direct functional equivalent with active product status, ROHS3 compliance, and REACH unaffected certification. Forward voltage matches at 2.1V. Brightness is lower at 1.8mcd, and power dissipation is higher at 80mW. Physical height is reduced to 0.673" compared to the original 0.750".

SA56-11YWA (Kingbright) is an active substitute with ROHS3 compliance and REACH unaffected certification. Physical dimensions match the original LTS-6860Y closely (0.750" height). Brightness is elevated at 6.5mcd. Forward voltage and current specifications align with the original part.

All three substitutes are available in production quantities and carry equivalent compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can HDSP-5701 replace LTS-6860Y in existing designs? A: Yes. HDSP-5701 meets all core electrical parameters: 7-segment, single character, 0.56" digit size, yellow color, common anode, 10-DIP package, 2.1V forward voltage, and 20mA test current. Physical height differs (0.673" vs 0.750"), which may affect mechanical fit in constrained spaces.

Q: What is the difference between HDSP-511Y and HDSP-5701? A: Both are Broadcom products with active status. HDSP-511Y has a forward voltage of 2.15V and lower power dissipation (52mW). HDSP-5701 operates at 2.1V with higher power dissipation (80mW). HDSP-511Y is the manufacturer-recommended substitute.

Q: Is SA56-11YWA suitable for high-brightness applications? A: SA56-11YWA delivers 6.5mcd, which is higher than the original LTS-6860Y (2.4mcd). If brightness matching is critical to circuit design, this part may require current-limiting adjustments.

Q: Are all substitutes RoHS compliant? A: HDSP-511Y, HDSP-5701, and SA56-11YWA are all ROHS3 compliant. The original LTS-6860Y RoHS status is not specified in the provided data.

Q: Can these parts be used interchangeably in PCB designs? A: All substitutes use the 10-DIP (0.600", 15.24mm) package with identical pin spacing. PCB footprints are compatible. Physical height variations (0.673" to 0.750") may affect mechanical clearance in designs with tight vertical constraints.

Q: What is the wavelength difference between substitutes? A: Peak wavelengths range from 583nm (HDSP-5701) to 595nm (HDSP-511Y), with the original at 585nm. These variations represent normal manufacturing tolerances within the yellow LED spectrum and do not affect functional compatibility.
