Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 4335 is based on alignment across the following critical parameters:

Mandatory Compatibility Parameters:

• Color: Green
• Type: Lens Cap
• Number of LEDs: 1
• Lens Style: Round with Flat Top
• Material: Polycarbonate
• Mounting Type: Snap-In (primary or secondary mounting capability)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Allowable Variations:

• Lens Size: 4.83mm (original) to 4.9mm (substitute) — within acceptable tolerance for general-purpose applications
• Optical Pattern: Wide (original) to Fresnel Ring (substitute) — both patterns provide light distribution suitable for indicator applications
• Lens Transparency: Not specified (original) to Clear (substitute) — transparency specification does not restrict substitution
• Mounting Type: Snap-In (original) to Panel Mount, Snap-In (substitute) — substitute supports both mounting methods

The substitute part SML_190_GTP maintains functional equivalence through shared core parameters while offering active product status and expanded mounting flexibility.

Parameter Comparison

Engineering Selection Recommendations

The VCC 4335 is obsolete and no longer in active production. The SML_190_GTP serves as the direct substitute for new designs and replacement applications.

Selection Basis:

The SML_190_GTP maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. The substitute is currently active in production with confirmed inventory availability (1957 pcs), providing supply continuity for ongoing applications.

Lens size variation from 4.83mm to 4.9mm represents a 0.07mm increase, which is within standard mechanical tolerance for snap-in lens cap applications. The Fresnel Ring optical pattern provides equivalent light distribution functionality compared to the Wide pattern of the original component.

The SML_190_GTP supports both Panel Mount and Snap-In mounting configurations, offering enhanced installation flexibility while maintaining backward compatibility with snap-in mounting requirements of the original 4335.

Frequently Asked Questions (FAQ)

Q: Can the SML_190_GTP directly replace the VCC 4335 in existing designs?

A: Yes. The SML_190_GTP maintains compatibility across all critical parameters: green color, single LED configuration, round flat-top lens style, polycarbonate material, snap-in mounting capability, and equivalent regulatory compliance (ROHS3, REACH Unaffected).

Q: What is the significance of the lens size difference between 4335 and SML_190_GTP?

A: The lens diameter increases from 4.83mm to 4.9mm, a difference of 0.07mm. This variation is within standard mechanical tolerance for snap-in lens cap assemblies and does not affect functional compatibility in general-purpose LED indicator applications.

Q: How do the optical patterns differ between Wide and Fresnel Ring?

A: Both patterns are designed to distribute light across a viewing area suitable for indicator applications. The Wide pattern of the 4335 and the Fresnel Ring pattern of the SML_190_GTP provide equivalent light distribution functionality for general-purpose use.

Q: Does the SML_190_GTP support snap-in mounting like the original 4335?

A: Yes. The SML_190_GTP supports both Panel Mount and Snap-In mounting types, providing compatibility with snap-in mounting requirements while offering additional Panel Mount capability.

Q: Are there any regulatory compliance differences between the two parts?

A: No. Both the VCC 4335 and SML_190_GTP are ROHS3 Compliant and REACH Unaffected, ensuring equivalent regulatory status for applications requiring these certifications.

Q: Why is the VCC 4335 listed as obsolete?

A: The 4335 has been discontinued by the manufacturer. The SML_190_GTP is the active production equivalent that fulfills the same functional requirements.
