APB3025ESGC Equivalent & Substitute Parts

Part Overview

The APB3025ESGC is an active-status, surface-mount LED indicator manufactured by Kingbright, featuring independent green and red light-emitting elements in a compact 4-SMD, no-lead package. This dual-color LED is designed for applications requiring simultaneous or alternating green/red indication with a clear, colorless lens and 120° viewing angle. The part is RoHS3 compliant and carries MSL 3 moisture sensitivity rating.

Substitute parts are identified to address inventory availability, regional sourcing requirements, or specific application constraints while maintaining functional equivalence within defined electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APB3025ESGC is determined by the following criteria:

Electrical Compatibility Parameters:

• Forward voltage (Vf) tolerance: ±0.2V maximum deviation per color channel
• Test current: 10mA to 20mA operating range
• Wavelength dominant: ±5nm tolerance for color matching (Green 563–573nm, Red 620–630nm)

Mechanical Compatibility Parameters:

• Mounting type: Surface Mount required
• Lens configuration: Independent dual-color, clear/colorless lens
• Package footprint: Maximum 3.20mm L x 2.70mm W (allows smaller or equal dimensions)
• Height: Maximum 1.10mm (allows equal or lesser height)
• Viewing angle: Minimum 120° (allows equal or greater angles)

Regulatory & Environmental Parameters:

• RoHS3 compliance mandatory
• MSL 3 rating or better
• REACH Unaffected status required

The LTST-C155GEKT from Lite-On Inc. meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

APB3025ESGC Selection Criteria:

• Primary choice when 12mcd brightness per color is required
• Preferred for applications with space constraints (3.00mm x 2.50mm footprint)
• Recommended when higher luminous intensity is specified in design requirements
• Active product status with 3100 units in stock ensures supply continuity

LTST-C155GEKT Selection Criteria:

• Acceptable substitute when lower brightness (6–7mcd per color) meets application requirements
• Suitable for applications tolerating slightly larger footprint (3.20mm x 2.70mm)
• Provides wider viewing angle (130° versus 120°), beneficial for broader visibility requirements
• Active product status with 1743 units in stock provides alternative sourcing
• Forward voltage compatibility (2.1V Green, 2.0V Red) allows direct circuit integration with minimal design adjustment

Both parts maintain identical RoHS3 compliance, MSL 3 rating, and REACH Unaffected status, ensuring regulatory equivalence for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can LTST-C155GEKT replace APB3025ESGC in existing PCB designs without layout modification?

A: The LTST-C155GEKT has a slightly larger footprint (3.20mm L x 2.70mm W versus 3.00mm L x 2.50mm W). PCB pad patterns designed for APB3025ESGC may require verification for LTST-C155GEKT compatibility. Both parts maintain identical 1.10mm maximum height and 4-SMD surface-mount configuration.

Q: What is the brightness difference between these two parts?

A: APB3025ESGC provides 12mcd per color (green and red). LTST-C155GEKT provides 7mcd green and 6mcd red. The APB3025ESGC is approximately 100% brighter for green and 100% brighter for red. Application visibility requirements determine acceptability of the lower brightness substitute.

Q: Are the forward voltages compatible with the same circuit design?

A: Forward voltages are within acceptable tolerance. APB3025ESGC operates at 2.2V green and 2.0V red; LTST-C155GEKT operates at 2.1V green and 2.0V red. The 0.1V variance in green channel is within standard LED circuit design margins and does not require circuit redesign.

Q: What is the difference in viewing angle between these parts?

A: APB3025ESGC provides 120° viewing angle; LTST-C155GEKT provides 130° viewing angle. The wider angle of LTST-C155GEKT allows visibility across a broader spatial range, beneficial for applications requiring wider indicator visibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both APB3025ESGC and LTST-C155GEKT are RoHS3 compliant with identical MSL 3 (168 Hours) moisture sensitivity ratings and REACH Unaffected status.

Q: What is the test current difference, and does it affect substitution?

A: APB3025ESGC is tested at 20mA per color; LTST-C155GEKT is tested at 10mA per color. Both parts operate within the 10–20mA range. The lower test current of LTST-C155GEKT indicates lower power consumption characteristics, which may be advantageous in battery-powered applications.

Q: Can I use LTST-C155GEKT if my design requires 12mcd brightness?

A: No. LTST-C155GEKT provides only 6–7mcd per color, which is insufficient for applications specifying 12mcd minimum brightness. APB3025ESGC is the required choice for this specification.
