Key Parameters

Substitute Part Grouping Explanation

The LE177SC39028 qualifies as a direct parametric equivalent to the LE177C39028 based on the following critical parameters:

• Identical voltage rating (24V DC) and current consumption (20mA)
• Matching lamp color, lens color, and lens transparency (green diffused)
• Identical lens style (round with flat top) and panel cutout specifications (0.50" round)
• Equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected)
• Same moisture sensitivity level (MSL 1 - Unlimited)

Both parts share the same base product number (LE177C) and maintain identical electrical performance characteristics and mechanical form factors required for panel mounting applications.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, the LE177C39028 is the recommended primary selection due to its active product status and higher inventory availability. This part maintains full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment for current and future applications.

The LE177SC39028 remains a valid functional equivalent for replacement or repair scenarios where the primary part is unavailable. Both parts deliver identical electrical performance and mechanical compatibility within 24V DC indicator light applications. Selection between these parts should be based on availability and project timeline requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can LE177SC39028 be used as a direct replacement for LE177C39028?

A: Yes. Both parts share identical electrical ratings (24V, 20mA), lens specifications (green diffused, round flat-top), and panel cutout dimensions (0.50" round). They are mechanically and electrically interchangeable.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. LE177C39028 is currently active in production, while LE177SC39028 has been discontinued at DiGi Electronics. All electrical and mechanical specifications remain identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both LE177C39028 and LE177SC39028 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What panel cutout size is required for installation?

A: Both parts require a 0.50" (12.70mm) round panel cutout. The lens style is round with a flat top, and the panel cutout shape is round.

Q: What is the moisture sensitivity level for these components?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which part should I specify for a new design?

A: Specify LE177C39028 for new designs. It is the active production part with established supply availability. LE177SC39028 should be reserved for legacy system replacements or when primary availability is constrained.
