VCC 4755 Green Snap-In Lens Cap - Equivalent & Substitute Parts

Part Overview

The VCC 4755 is a green snap-in lens cap designed for single LED applications. It features a round domed top lens with 9.65mm diameter and diffused transparency, constructed from polycarbonate material. The component is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, identifying equivalent substitute parts is essential for ongoing maintenance, repair, and component sourcing in legacy systems and equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 4755 is determined by the following critical parameters:

• Color: Green (must match)
• Lens Size: 9.65mm Dia (must match)
• Number of LEDs: 1 (must match)
• Mounting Type: Snap-In (must match)
• Material: Polycarbonate (must match)
• Lens Transparency: Diffused (must match)

The VCC 4745 qualifies as a substitute part because it maintains identical specifications across all critical parameters. The primary distinction between these parts is the lens style geometry: the 4755 features a domed top, while the 4745 features a convex top. Both lens geometries are compatible with single LED snap-in applications using 9.65mm diameter openings and provide equivalent optical diffusion characteristics.

Parameter Comparison

Engineering Selection Recommendations

The VCC 4745 is functionally equivalent to the VCC 4755 for applications requiring a green snap-in lens cap with 9.65mm diameter and diffused optical properties for single LED indicators.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in current manufacturing and assembly environments.

Product Status Consideration: The VCC 4755 is classified as obsolete, while the VCC 4745 is classified as not for new designs. For legacy system maintenance and repair applications, the VCC 4745 provides continued component availability with equivalent electrical and mechanical performance.

Lens Geometry Difference: The substitution involves a change from domed top to convex top lens geometry. Both geometries accommodate the same 9.65mm snap-in mounting interface and deliver identical diffused light transmission characteristics. The geometric variation does not affect functional compatibility in standard LED indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the VCC 4745 directly replace the VCC 4755 in existing assemblies?

A: Yes. Both parts share identical mounting type (snap-in), lens diameter (9.65mm), color (green), transparency (diffused), and material (polycarbonate). The lens geometry difference (domed versus convex top) does not affect mechanical fit or optical performance in standard single LED indicator circuits.

Q: What is the primary difference between these two parts?

A: The lens style geometry differs. The VCC 4755 features a round domed top, while the VCC 4745 features a round convex top. All other specifications, including size, color, transparency, and mounting method, are identical.

Q: Are there packaging differences between the VCC 4755 and VCC 4745?

A: Yes. The VCC 4755 is supplied in bulk packaging, while the VCC 4745 is supplied in bag packaging. This distinction affects inventory management and handling procedures but does not impact component performance or compatibility.

Q: Why is the VCC 4755 classified as obsolete?

A: The VCC 4755 is no longer manufactured by Visual Communications Company. The VCC 4745 remains available as a substitute for ongoing support of legacy equipment and systems.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the VCC 4755 and VCC 4745 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: Can the VCC 4745 be used in new product designs?

A: The VCC 4745 is classified as not for new designs. For new applications, consult VCC documentation for current production alternatives that meet modern design requirements.
