Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VCC 4376 is determined by the following critical parameters:

Primary Compatibility Criteria:

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

Secondary Consideration Parameters:

• Lens Size (9.9mm diameter for 4376)
• Lens Transparency (Diffused for 4376)
• Optical Pattern (Wide for 4376)
• Product Status (Active preferred for obsolete parts)

The substitute part CLB_300_BTP shares the core compatibility criteria of manufacturer, color, material, snap-in mounting, and compliance certifications. Variations in lens size, lens transparency, and optical pattern represent design trade-offs acceptable within the general-purpose LED indicator application category.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The VCC 4376 is classified as obsolete. The CLB_300_BTP is an active product from the same manufacturer and meets all primary compatibility requirements: identical color (blue), material (polycarbonate), mounting interface (snap-in), LED count (1), and compliance certifications (ROHS3, MSL 1).

Mechanical Considerations:

The CLB_300_BTP features a smaller lens diameter (7.11mm versus 9.9mm) and different lens transparency and optical characteristics. These differences require mechanical and optical validation within the specific application context. The substitute part supports both panel mount and snap-in configurations, providing mounting flexibility.

Compliance Status:

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The CLB_300_BTP carries active product status, supporting long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CLB_300_BTP directly replace VCC 4376 in existing designs?

A: CLB_300_BTP shares the core compatibility parameters (manufacturer, color, material, snap-in mounting, compliance certifications). However, the smaller lens diameter (7.11mm versus 9.9mm), different lens transparency (clear versus diffused), and different optical pattern (Fresnel Ring versus Wide) require mechanical and optical validation for the specific application.

Q: What are the key differences between these parts?

A: The primary differences are lens size, lens transparency, and optical pattern. The 4376 features a 9.9mm diffused lens with wide optical pattern, while the CLB_300_BTP features a 7.11mm clear lens with Fresnel Ring pattern. Both use polycarbonate material and snap-in mounting.

Q: Is CLB_300_BTP available for procurement?

A: CLB_300_BTP is classified as active product status with 2273 units in stock, supporting immediate procurement. The VCC 4376 is obsolete with limited remaining inventory.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating, meeting standard environmental and moisture sensitivity requirements.

Q: What mounting configurations does CLB_300_BTP support?

A: CLB_300_BTP supports both panel mount and snap-in mounting types, providing greater mounting flexibility compared to the 4376 snap-in configuration.
