LE177WL5G LED Panel Indicator - Equivalent & Substitute Parts

Part Overview

The LE177WL5G is an LED panel indicator light manufactured by Bulgin, designed for AC applications in the 125V to 250V range. This component features a green diffused lens with round flat-top styling and 8-inch wire leads for direct panel mounting through a 0.50-inch round cutout. The part operates at 3mA and is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory depletion, or when design flexibility allows for functionally equivalent alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The LE67WL5G qualifies as a parametric equivalent to the LE177WL5G based on strict alignment across all critical electrical and mechanical parameters. Substitution eligibility is determined by matching the following specifications:

• Identical lamp color (Green) and lens color (Green)
• Identical lens transparency (Diffused) and lens style (Round with Flat Top)
• Identical voltage rating (125V ~ 250V AC) and current rating (3mA)
• Identical panel cutout shape (Round) and dimensions (0.50" / 12.70mm)
• Identical termination style (Wire Leads - 8" / 203.20mm)
• Equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected)

The LE67WL5G maintains full functional and physical compatibility with the LE177WL5G in all applications where these parameters are specified.

Parameter Comparison

Engineering Selection Recommendations

The LE177WL5G is the recommended primary selection for new designs and procurement due to its active product status and current availability. This part maintains full ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

The LE67WL5G serves as a direct functional substitute when the LE177WL5G is unavailable or when existing inventory of the LE67WL5G is present in supply chains. Although discontinued at DiGi Electronics, the LE67WL5G maintains identical electrical performance, mechanical compatibility, and compliance certifications. Selection between these parts should be based on availability and supply chain considerations rather than technical performance differences.

Both parts are suitable for AC-rated panel indicator applications requiring green illumination in the 125V to 250V operating range with 3mA current consumption.

Frequently Asked Questions (FAQ)

Q: Can the LE67WL5G replace the LE177WL5G in existing applications?

A: Yes. The LE67WL5G is a parametric equivalent with identical electrical ratings (125V ~ 250V AC, 3mA), mechanical dimensions (0.50-inch round cutout, 8-inch wire leads), and optical properties (green diffused lens, round flat-top style). Direct substitution is valid for all applications where the LE177WL5G is specified.

Q: What is the difference between these two parts?

A: The LE177WL5G and LE67WL5G differ only in product status. The LE177WL5G is currently active in production, while the LE67WL5G is discontinued at DiGi Electronics. All electrical, mechanical, and compliance specifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the LE177WL5G and LE67WL5G carry ROHS3 compliance certification and REACH unaffected status, meeting regulatory requirements for industrial applications.

Q: What panel cutout dimensions are required for installation?

A: Both parts require a 0.50-inch (12.70mm) round cutout for panel mounting. The wire leads extend 8 inches (203.20mm) for connection to external circuitry.

Q: Can these parts be used in DC applications?

A: No. Both the LE177WL5G and LE67WL5G are rated for AC applications only at 125V ~ 250V. They are not suitable for DC circuits.
