VCC 4752 Lens Clear Snap-In: Equivalent & Substitute Parts

Part Overview

The VCC 4752 is a clear snap-in lens cap designed for single LED applications. This component features a round domed polycarbonate lens with a 9.65mm diameter and diffused transparency characteristics. The part is classified as obsolete, making identification of equivalent alternatives essential for ongoing production support and component sourcing.

The obsolete status necessitates evaluation of available substitute components to maintain design compatibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 4752 is determined by the following critical parameters:

Primary Substitution Criteria:

• Mounting Type: Snap-In
• Lens Size: 9.65mm Diameter
• Lens Style: Round with Domed Top
• Material: Polycarbonate
• Color: Clear
• Number of LEDs: 1
• Lens Transparency: Diffused

The identified substitute part (Adafruit Industries LLC 4742) has been listed in the original manufacturer's substitution field. However, evaluation of this substitute against the primary substitution criteria reveals significant functional differences that must be considered during component selection.

Parameter Comparison

Engineering Selection Recommendations

Critical Compatibility Assessment:

The Adafruit 4742 listed as a substitute part is functionally distinct from the VCC 4752. The VCC 4752 is a passive optical lens cap component, while the Adafruit 4742 is an active ultrasonic distance sensor. These components serve fundamentally different functions and cannot be considered direct mechanical or electrical equivalents.

Compliance Considerations:

Both components share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited) and ECCN classification (EAR99), indicating compatible handling and export compliance profiles. The VCC 4752 maintains ROHS3 compliance and REACH unaffected status; the Adafruit 4742 compliance certifications are not specified in available documentation.

Sourcing Recommendation:

For applications requiring the specific optical and mechanical characteristics of the VCC 4752 (clear snap-in lens cap, 9.65mm diameter, domed polycarbonate construction), direct equivalent components from active manufacturers should be prioritized. The listed substitute should be evaluated only if application requirements permit functional substitution with an ultrasonic sensor component.

Frequently Asked Questions (FAQ)

Q: Can the Adafruit 4742 directly replace the VCC 4752 in existing designs?

A: No. The Adafruit 4742 is an ultrasonic distance sensor, not a lens cap. Direct substitution is not possible without significant circuit and mechanical redesign.

Q: What makes the VCC 4752 difficult to source?

A: The VCC 4752 is classified as obsolete, meaning the manufacturer has discontinued production. Alternative sourcing requires identification of equivalent lens cap components from active manufacturers with matching mechanical and optical specifications.

Q: Are there compliance differences between these parts?

A: Both components share EAR99 classification and MSL 1 ratings. The VCC 4752 specifies ROHS3 compliance and REACH unaffected status. The Adafruit 4742 compliance documentation does not specify these certifications.

Q: What parameters must match for a valid substitute lens cap?

A: Valid substitutes must match: mounting type (snap-in), lens diameter (9.65mm), lens style (round domed), material (polycarbonate), color (clear), and transparency (diffused).

Q: Is the MSL 1 rating important for this component?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions during storage or handling. This rating is consistent across both components and does not present a substitution barrier.
