LED Circuit Board Indicator SSF-LXH340GYID Equivalent & Substitute Parts

Part Overview

The SSF-LXH340GYID is a tri-color LED circuit board indicator manufactured by Lumex Opto/Components Inc. This component integrates three individual LEDs (green, red, and yellow) in a single 3mm T-1 package with right-angle through-hole mounting. The device is designed for applications requiring compact multi-color status indication on printed circuit boards.

The SSF-LXH340GYID maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary for supply chain continuity, design flexibility, and procurement optimization when the primary part experiences extended lead times or inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSF-LXH340GYID are identified based on strict equivalence across the following critical parameters:

Physical & Mechanical Compatibility:

• Configuration: 3 High (three individual LEDs in single package)
• Color arrangement: Green, Red, Yellow
• Lens size: 3mm, T-1 standard
• Lens style: Round with Domed Top
• Mounting type: Through Hole, Right Angle

Electrical Compatibility:

• Voltage ratings within specified ranges for each color
• Current capability sufficient for 20mA operation
• Color wavelengths consistent with standard tri-color LED specifications

Regulatory & Environmental:

• RoHS3 compliance
• MSL 1 rating
• REACH unaffected status
• ECCN EAR99 classification

The substitute part 5640100132F from Dialight meets all these criteria, maintaining identical physical form factor, mounting configuration, and regulatory compliance while providing equivalent functional performance in tri-color LED indication applications.

Engineering Selection Recommendations

Primary Part: SSF-LXH340GYID

The SSF-LXH340GYID remains the primary selection when available. This part carries Active product status with established supply channels and full technical documentation from Lumex Opto/Components Inc.

Substitute Part: 5640100132F

The Dialight 5640100132F serves as a direct functional equivalent when SSF-LXH340GYID availability is constrained. Both parts maintain identical physical dimensions, mounting configuration, and regulatory compliance profiles. The substitute part is available in higher inventory quantities (5000 pcs vs. 677 pcs), providing supply chain advantages.

Regulatory & Compliance Alignment:

Both parts satisfy identical compliance requirements:

• RoHS3 Directive compliance
• REACH unaffected classification
• EAR99 export control status
• HTSUS commodity code 8541.41.0000
• MSL 1 moisture sensitivity rating

Voltage Compatibility Note:

The SSF-LXH340GYID specifies 2.2V for green operation, while the 5640100132F specifies 2.1V for green operation. Both values fall within acceptable operating ranges for standard green LED applications. Circuit designs accommodating the SSF-LXH340GYID specification will operate the 5640100132F substitute without functional degradation.

Selection Criteria:

Use SSF-LXH340GYID when:

• Established design validation exists for this specific part number
• Supply is available within required lead time
• Design documentation references Lumex specifications

Use 5640100132F when:

• SSF-LXH340GYID experiences extended lead times or allocation
• Higher inventory availability is required for production volume
• Dialight supply chain relationships provide procurement advantage
• Physical form factor and mounting configuration are the primary design constraints

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5640100132F directly replace the Lumex SSF-LXH340GYID without PCB modification?

A: Yes. Both parts share identical physical dimensions (3mm T-1), lens style (round domed top), and right-angle through-hole mounting configuration. No PCB layout changes are required for mechanical compatibility.

Q: Are there electrical differences between these parts that affect circuit design?

A: Both parts operate at equivalent voltage levels for red (2V) and yellow (2.1V) LEDs. The green LED voltage differs slightly (2.2V vs. 2.1V), but this difference is within standard LED operating tolerances and does not require circuit redesign. Current-limiting resistor values calculated for the SSF-LXH340GYID will function correctly with the 5640100132F.

Q: What is the significance of the millicandela ratings provided for the Dialight part?

A: The Dialight 5640100132F specifies brightness levels (12.6mcd green, 10mcd red, 10mcd yellow) with a 60° viewing angle. These values define the luminous intensity and visibility characteristics. If the original design does not specify brightness requirements, these ratings indicate the substitute part provides adequate indication visibility for standard circuit board applications.

Q: Are both parts suitable for high-temperature or harsh environment applications?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating they are not moisture-sensitive and suitable for standard manufacturing and storage conditions. Temperature and environmental specifications beyond MSL rating are not provided in the available data. Consult detailed datasheets for specific thermal or environmental operating limits.

Q: What packaging differences exist between these parts?

A: The SSF-LXH340GYID is supplied in standard packaging (not specified), while the Dialight 5640100132F is supplied in Bulk packaging. Both are suitable for through-hole assembly processes. Bulk packaging typically accommodates higher-volume production requirements.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Both parts meet identical regulatory compliance standards (RoHS3, REACH, EAR99) and share the same physical form factor and mounting type. Designs validated for the SSF-LXH340GYID will function with the 5640100132F substitute. However, design teams should verify that brightness levels and color wavelengths align with application requirements before production implementation.

Q: What is the base product number significance?

A: The base product number identifies the core product family. SSF-LXH340 (Lumex) and 5640100 (Dialight) represent the tri-color 3mm LED indicator family from each manufacturer. The suffix characters (-GYID and -F) denote specific color configurations and packaging variants within each family.
