SECU180EC-SA Equivalent & Substitute Parts

Part Overview

The SECU180EC-SA is an amber 611nm surface-mount LED indicator manufactured by Sanken Electric USA Inc. This component is designed for discrete indication applications requiring a 2V forward voltage with 200 millicandela brightness output. The part is currently in active production status with 948 units available in new original inventory. Alternative part selection becomes necessary when addressing supply chain constraints, regional availability, or specific procurement requirements while maintaining identical electrical and mechanical performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the SECU180EC-SA is determined by strict equivalence across the following critical parameters:

Electrical Characteristics:

• Forward voltage (Vf): 2V nominal
• Test current: 20mA
• Wavelength dominant: 611nm amber spectrum
• Brightness output: 200 millicandela

Mechanical & Optical Characteristics:

• Lens style: Rectangle with flat top geometry
• Lens dimensions: 3.00mm length × 1.40mm width
• Maximum height: 1.40mm
• Viewing angle: 120°

Package & Environmental Specifications:

• Package type: 2-SMD, J-Lead configuration
• Mounting: Surface mount technology
• Packaging format: Tape & Reel (TR)
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 3 (168 hours)

Only components matching all specified parameters across these categories qualify as direct substitutes. No parameter relaxation or tolerance variation is permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

The SECU180EC-SA maintains active product status with confirmed inventory availability. Component selection should prioritize parts with identical electrical specifications (2V forward voltage, 20mA test current, 611nm wavelength, 200mcd output) and mechanical compatibility (2-SMD J-Lead package, 3.00mm × 1.40mm lens dimensions, 1.40mm maximum height).

All substitute candidates must maintain ROHS3 compliance and MSL 3 (168 hours) moisture sensitivity classification to ensure regulatory and environmental performance parity. Surface mount packaging in tape and reel format is required for automated assembly compatibility.

Active product status confirmation ensures long-term supply chain stability and continued manufacturer support for technical documentation and quality assurance.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the SECU180EC-SA?

A: A valid substitute must match all electrical parameters (2V Vf, 20mA test current, 611nm wavelength, 200mcd brightness), mechanical dimensions (3.00mm × 1.40mm lens, 1.40mm height), package configuration (2-SMD J-Lead), and compliance certifications (ROHS3, MSL 3).

Q: Can LEDs with different wavelengths substitute for the 611nm amber specification?

A: No. The 611nm dominant wavelength is a critical specification for color-matched indication applications. Wavelength substitution alters the perceived color and is not permitted.

Q: Are different lens styles compatible with this application?

A: No. The rectangle with flat top lens style is specified for this component. Alternative lens geometries (dome, diffused, or other shapes) are not compatible substitutes.

Q: What is the significance of the 2-SMD J-Lead package specification?

A: The 2-SMD J-Lead package defines the physical footprint, lead configuration, and PCB mounting pattern. This package type is required for compatibility with existing circuit board designs and automated assembly equipment.

Q: Does MSL 3 (168 Hours) affect component handling?

A: Yes. MSL 3 classification requires controlled storage conditions and limits the component's exposure to moisture before soldering. Handling procedures must comply with IPC-A-610 standards for MSL 3 components.

Q: Is the SECU180EC-SA suitable for applications requiring different brightness levels?

A: No. The 200mcd specification is fixed for this part number. Applications requiring different brightness levels require alternative part numbers with different millicandela ratings.

Q: Can this component be used in non-surface-mount applications?

A: No. The SECU180EC-SA is specified exclusively for surface mount technology. Through-hole or other mounting methods are not supported by this package configuration.
