Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 4375 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: Visual Communications Company - VCC
• Type: Lens Cap
• Color: Green
• Number of LEDs: 1
• Material: Polycarbonate
• Mounting Type: Snap-In
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute part CLB_300_GTP shares all primary compatibility criteria with the main part. Both components are manufactured by VCC, feature green polycarbonate construction, support single LED applications, utilize snap-in mounting, and maintain identical RoHS and MSL ratings. Variations in lens diameter (9.9mm vs. 7.11mm), lens style (round domed vs. round convex), optical pattern (wide vs. Fresnel ring), and transparency (diffused vs. clear) represent secondary design parameters that may influence optical performance characteristics but do not preclude functional substitution in general-purpose applications.

Engineering Selection Recommendations

CLB_300_GTP as Primary Substitute:

The CLB_300_GTP is the designated substitute for the obsolete VCC 4375. This part maintains active product status with VCC, ensuring ongoing availability and supply chain continuity. Both components satisfy identical regulatory requirements, including ROHS3 compliance and MSL Level 1 rating, confirming compatibility within environmentally controlled storage and handling protocols.

The CLB_300_GTP supports panel mount and snap-in mounting configurations, providing mechanical flexibility for retrofit applications. The smaller lens diameter (7.11mm vs. 9.9mm) and alternative optical characteristics (Fresnel ring vs. wide pattern, clear vs. diffused transparency) represent design trade-offs that must be evaluated against specific application requirements. These differences do not compromise the fundamental functional equivalence of the components within general-purpose LED indicator applications.

Selection of CLB_300_GTP is appropriate for new designs and component replenishment where the obsolete 4375 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can CLB_300_GTP directly replace VCC 4375 in existing assemblies?

A: CLB_300_GTP shares core functional characteristics with the 4375, including green color, single LED support, polycarbonate construction, snap-in mounting, and identical compliance ratings. The smaller lens diameter (7.11mm vs. 9.9mm) and different optical patterns (Fresnel ring vs. wide) may require mechanical and optical validation in specific applications. Panel mount capability of the CLB_300_GTP provides additional mounting flexibility.

Q: What are the key differences between these parts?

A: Primary differences include lens diameter, lens geometry, optical transparency, and optical pattern. The 4375 features a 9.9mm domed lens with wide diffused optics, while the CLB_300_GTP provides a 7.11mm convex lens with Fresnel ring clear optics. Both parts maintain identical electrical and compliance specifications.

Q: Are both parts RoHS compliant?

A: Both the VCC 4375 and CLB_300_GTP are ROHS3 compliant, confirming restriction of hazardous substances in accordance with applicable regulations.

Q: What is the MSL rating for these components?

A: Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage and handling.

Q: Why is the 4375 listed as obsolete?

A: The VCC 4375 has reached end-of-life status. The CLB_300_GTP remains in active production and serves as the current equivalent offering from VCC for green lens cap applications.

Q: Are there packaging differences between these parts?

A: The 4375 is available in standard packaging, while the CLB_300_GTP is supplied in bulk packaging format.
