Substitute Part Grouping Explanation

Substitute parts for the NL177C3R are qualified based on the following critical parameters that determine functional interchangeability:

• Voltage Rating: 250V (exact match required)
• Lamp Color: Red (exact match required)
• Lens Color: Red (exact match required)
• Lens Transparency: Diffused (exact match required)
• Panel Cutout Shape: Round (exact match required)
• Panel Cutout Dimensions: 0.50" (12.70mm) (exact match required)
• Lens Style: Round with Flat Top (exact match required)
• Product Type: Neon (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)

All substitute parts listed maintain identical electrical and mechanical specifications to the main part, ensuring direct replacement capability without modification to panel cutouts or electrical connections.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—NL180AAC3R, NL67C3R, and NL67H3R—are qualified equivalents for the NL177C3R based on identical electrical specifications, mechanical form factor, and regulatory compliance. Selection among these parts may be based on inventory availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can NL180AAC3R, NL67C3R, or NL67H3R be used as direct replacements for NL177C3R?

A: Yes. All three parts are parametric equivalents with identical voltage rating (250V), lamp color (Red), lens color (Red), lens transparency (Diffused), panel cutout dimensions (0.50" / 12.70mm), and lens style (Round with Flat Top). No panel modification or electrical reconfiguration is required.

Q: What determines whether a neon indicator light can substitute for the NL177C3R?

A: Substitution is determined by exact matching of voltage rating, lamp color, lens color, lens transparency, panel cutout shape, panel cutout dimensions, and lens style. All substitute parts listed meet these criteria.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. NL180AAC3R, NL67C3R, and NL67H3R are all ROHS3 compliant and REACH unaffected, matching the regulatory status of the NL177C3R.

Q: What is the difference between the substitute part numbers?

A: The substitute parts differ only in their base product numbers (NL180, NL67C3, NL67H3) and internal design variations. Electrical and mechanical specifications remain identical, ensuring functional equivalence in panel indicator applications.

Q: Is inventory availability a factor in part selection?

A: Inventory levels vary among substitute parts. NL67H3R maintains the highest inventory (1075 Pcs), followed by NL67C3R (985 Pcs) and NL180AAC3R (663 Pcs). Selection may be influenced by lead time and supply chain requirements.
