Equivalent & Substitute Parts for VCC 4312 Lens Cap

Part Overview

The VCC 4312 is a clear lens cap designed for single LED applications with a 180° wide viewing angle. This component features a round flat-top design with a 7.11mm diameter and snap-in mounting configuration. The part is classified as obsolete, necessitating identification of active equivalent components to maintain supply chain continuity for applications requiring this lens cap specification.

Substitute Part Grouping Explanation

The CLF_280_CTP qualifies as a substitute for the VCC 4312 based on the following critical parameters:

Matching Parameters:

• Lens size: 7.11mm diameter (identical)
• Lens style: Round with flat top (identical)
• Color: Clear (identical)
• Material: Polycarbonate (identical)
• Number of LEDs: 1 (identical)
• Mounting type: Snap-In (compatible)
• RoHS compliance: ROHS3 Compliant (equivalent regulatory status)
• Manufacturer: Visual Communications Company - VCC (same manufacturer)

Differing Parameters:

• Optical pattern: Wide (4312) versus Fresnel Ring (CLF_280_CTP)
• Viewing angle: 180° (4312) versus not specified (CLF_280_CTP)
• Product status: Obsolete (4312) versus Active (CLF_280_CTP)
• Mounting configuration: Snap-In only (4312) versus Panel Mount and Snap-In (CLF_280_CTP)

The substitution is valid for applications where the Fresnel Ring optical pattern and panel mount capability of the CLF_280_CTP are compatible with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The CLF_280_CTP is an active equivalent component manufactured by the same supplier (VCC) and maintains identical physical dimensions and material specifications as the obsolete VCC 4312. Both components satisfy ROHS3 compliance requirements and are constructed from polycarbonate material suitable for general-purpose LED applications.

The primary distinction between these components is the optical pattern specification. The 4312 features a wide optical pattern with a 180° viewing angle, while the CLF_280_CTP incorporates a Fresnel Ring optical pattern. The CLF_280_CTP additionally provides panel mount capability in addition to snap-in mounting, offering greater installation flexibility.

Selection of the CLF_280_CTP as a replacement for the VCC 4312 is appropriate for applications where the Fresnel Ring optical characteristics are functionally compatible with the original design. The active product status and substantially higher inventory availability (48431 units) of the CLF_280_CTP support its use as a long-term supply solution for the obsolete 4312 component.

Frequently Asked Questions (FAQ)

Q: What are the critical physical parameters that determine compatibility between the VCC 4312 and CLF_280_CTP?

A: The lens diameter (7.11mm), lens style (round with flat top), material (polycarbonate), and mounting type (snap-in) are identical between both components. These parameters establish the mechanical and dimensional compatibility required for direct substitution in existing assemblies.

Q: How do the optical patterns differ between these two lens caps?

A: The VCC 4312 features a wide optical pattern with a 180° viewing angle specification. The CLF_280_CTP incorporates a Fresnel Ring optical pattern. The Fresnel Ring design uses concentric rings to modify light distribution characteristics compared to the wide pattern of the 4312.

Q: Are both components RoHS compliant?

A: Yes. Both the VCC 4312 and CLF_280_CTP are ROHS3 compliant, meeting equivalent regulatory requirements for hazardous substance restrictions.

Q: What is the difference in mounting configuration between these parts?

A: The VCC 4312 provides snap-in mounting only. The CLF_280_CTP offers both panel mount and snap-in mounting options, providing additional installation flexibility for different circuit board configurations.

Q: Why is the CLF_280_CTP recommended despite the optical pattern difference?

A: The CLF_280_CTP is an active product with substantial inventory availability (48431 units), whereas the VCC 4312 is obsolete. The identical physical dimensions, material composition, and snap-in mounting capability make the CLF_280_CTP functionally compatible for applications where the Fresnel Ring optical pattern is acceptable.

Q: What is the packaging difference between these components?

A: The VCC 4312 packaging specification is not detailed in the available data. The CLF_280_CTP is supplied in bulk packaging format.
