Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 4371 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Number of LEDs: 1
• Material: Polycarbonate
• Mounting Type: Snap-In capability
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Lens Size: 9.9mm diameter represents the primary form factor; substitute parts with different lens sizes may require mechanical redesign of mounting interfaces

The CLB_300_RTP meets the primary compatibility criteria as a red, single-LED polycarbonate lens cap with snap-in mounting and equivalent environmental compliance ratings. Differences in lens style (convex vs. domed), optical pattern (Fresnel Ring vs. Wide), and lens size (7.11mm vs. 9.9mm) represent functional variations that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The CLB_300_RTP is classified as an active product with current manufacturing support, providing supply chain continuity for applications currently using the obsolete VCC 4371. Both components maintain equivalent environmental compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1).

Selection Considerations:

The CLB_300_RTP differs from the VCC 4371 in three functional parameters: lens diameter (7.11mm vs. 9.9mm), lens transparency (clear vs. diffused), and optical pattern (Fresnel Ring vs. Wide). These differences directly affect light distribution characteristics and mechanical fit within existing assemblies. Component selection must account for these variations relative to specific application requirements.

Both components utilize polycarbonate construction with snap-in mounting and are suitable for general-purpose LED applications. The CLB_300_RTP supports both panel mount and snap-in configurations, providing additional mounting flexibility.

Frequently Asked Questions (FAQ)

Q: Can the CLB_300_RTP directly replace the VCC 4371 in existing assemblies?

A: Direct mechanical replacement requires verification of lens diameter compatibility. The CLB_300_RTP features a 7.11mm diameter lens compared to the VCC 4371's 9.9mm diameter. Mounting interfaces designed for the larger diameter may require modification.

Q: What are the optical differences between these components?

A: The VCC 4371 provides a wide optical pattern through a diffused domed lens, while the CLB_300_RTP uses a Fresnel Ring pattern with a clear convex lens. These configurations produce different light distribution characteristics suitable for different viewing angle requirements.

Q: Are both components compliant with current environmental regulations?

A: Both the VCC 4371 and CLB_300_RTP are ROHS3 Compliant and REACH Unaffected, meeting current environmental standards. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the availability status of each component?

A: The VCC 4371 is classified as obsolete with 951 pieces in current inventory. The CLB_300_RTP is an active product with 2153 pieces in inventory, providing ongoing supply availability.

Q: Are there packaging differences between these components?

A: The VCC 4371 is supplied with standard packaging, while the CLB_300_RTP is supplied in bulk packaging format.
