Equivalent & Substitute Parts for VCC 4311 Red Lens Cap

Part Overview

The VCC 4311 is a red lens cap designed for general-purpose LED applications with a 180° wide viewing angle. This component features a round flat-top design with a 7.11mm diameter snap-in mounting interface and is constructed from polycarbonate material. The 4311 is classified as obsolete, necessitating identification of active substitute components that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 4311 is determined by the following critical parameters that must align between the main part and substitute components:

Primary Compatibility Criteria:

• Color: Red
• Lens Size: 7.11mm Dia
• Lens Style: Round with Flat Top
• Material: Polycarbonate
• Mounting Type: Snap-In (primary interface requirement)
• RoHS Compliance: ROHS3 Compliant

The CLF_280_RTP qualifies as a substitute based on matching these core parameters. While the CLF_280_RTP features a Fresnel Ring optical pattern compared to the 4311's wide pattern, and includes panel mount capability in addition to snap-in mounting, the fundamental mechanical and electrical compatibility is maintained through identical lens diameter, material composition, color specification, and snap-in interface.

Parameter Comparison

Engineering Selection Recommendations

The CLF_280_RTP serves as the active substitute for the obsolete VCC 4311 based on the following engineering criteria:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental standards.

Mechanical Compatibility: The CLF_280_RTP retains the identical 7.11mm lens diameter and snap-in mounting interface, enabling direct mechanical substitution in existing snap-in socket designs without modification to the host assembly.

Material and Construction: Polycarbonate material specification is maintained across both components, preserving optical and thermal characteristics of the original design.

Product Availability: The CLF_280_RTP is classified as active with substantial inventory availability (21,827 pcs), whereas the 4311 is obsolete. Selection of the CLF_280_RTP ensures long-term supply continuity and eliminates obsolescence risk.

Optical Characteristics: The CLF_280_RTP incorporates a Fresnel Ring optical pattern with clear lens transparency, differing from the 4311's wide pattern specification. Applications requiring the specific 180° wide viewing angle characteristic of the 4311 should evaluate whether the Fresnel Ring pattern meets optical performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the CLF_280_RTP directly replace the VCC 4311 in existing assemblies?

A: The CLF_280_RTP is mechanically compatible with snap-in socket interfaces designed for the 4311 due to matching lens diameter (7.11mm) and snap-in mounting type. However, the optical pattern differs (Fresnel Ring vs. Wide), which may affect light distribution characteristics in the application.

Q: What is the primary reason for substituting the 4311?

A: The VCC 4311 is classified as obsolete. The CLF_280_RTP is an active product with reliable supply availability, making it the appropriate choice for new designs and ongoing production requiring red lens caps with 7.11mm snap-in interfaces.

Q: Are there compliance differences between the two parts?

A: Both components maintain identical regulatory compliance: ROHS3 compliant, REACH unaffected, and EAR99 export classification. No compliance barriers exist to substitution.

Q: What mounting options does the CLF_280_RTP provide?

A: The CLF_280_RTP supports both panel mount and snap-in mounting types, providing greater flexibility than the 4311's snap-in-only configuration. Applications using snap-in interfaces will function identically to the original design.

Q: How do the optical patterns differ between these components?

A: The 4311 features a wide optical pattern with a 180° viewing angle specification. The CLF_280_RTP incorporates a Fresnel Ring optical pattern with clear lens transparency. The specific viewing angle for the CLF_280_RTP is not specified in the component data. Applications with critical viewing angle requirements should evaluate whether the Fresnel Ring pattern meets performance specifications.

Q: Is the CLF_280_RTP available in the same packaging as the 4311?

A: The CLF_280_RTP is supplied in bulk packaging, whereas the 4311 packaging specification is not detailed in the component data. Packaging format should be confirmed with the supplier based on production volume requirements.
