Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 4336 is based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Color: Blue
• Lens Style: Round with Flat Top
• Material: Polycarbonate
• Mounting Type: Snap-In
• RoHS Compliance: ROHS3 Compliant
• Regulatory Status: REACH Unaffected, ECCN EAR99

Secondary Compatibility Considerations:

• Lens Size: 4.83mm Dia (main part) versus 4.9mm Dia (substitute)
• Optical Pattern: Wide (main part) versus Fresnel Ring (substitute)
• Mounting Configuration: Snap-In only (main part) versus Panel Mount, Snap-In (substitute)

The substitute part SML_190_BTP maintains core compatibility through identical color, lens style, material, and primary mounting method. Variations in lens size, optical pattern, and mounting configuration options represent design differences that must be evaluated within the specific application context.

Engineering Selection Recommendations

VCC 4336 to SML_190_BTP Substitution Assessment:

The SML_190_BTP represents an active equivalent for the obsolete VCC 4336 based on the following engineering factors:

Compliance Alignment: Both components maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification, ensuring regulatory continuity in applications requiring these certifications.

Mechanical Compatibility: Both components feature identical lens style (round with flat top), material composition (polycarbonate), and primary mounting method (snap-in). The SML_190_BTP provides expanded mounting flexibility through additional panel mount capability, which does not preclude snap-in installation.

Dimensional Considerations: The lens diameter increases from 4.83mm to 4.9mm, representing a 0.07mm increase. This dimensional variance requires verification against specific mechanical envelope constraints in the target application.

Optical Pattern Variance: The optical pattern differs between components: the VCC 4336 provides wide distribution, while the SML_190_BTP employs Fresnel ring pattern. This optical characteristic difference directly affects light distribution and viewing angle performance and must be evaluated against application requirements.

Product Status: The SML_190_BTP maintains active product status with documented inventory availability, ensuring long-term supply chain continuity compared to the obsolete VCC 4336.

Frequently Asked Questions (FAQ)

Q: Can the SML_190_BTP directly replace the VCC 4336 in existing designs?

A: The SML_190_BTP shares core compatibility parameters including color, lens style, material, and snap-in mounting. However, the optical pattern difference (wide versus Fresnel ring) and lens diameter variance (4.83mm versus 4.9mm) require evaluation against specific application optical and mechanical requirements before implementation.

Q: What are the key differences between these two lens caps?

A: The primary differences are optical pattern (wide versus Fresnel ring), lens diameter (4.83mm versus 4.9mm), lens transparency specification (not specified versus clear), and mounting options (snap-in only versus panel mount and snap-in). Both maintain identical color, lens style, material, and regulatory compliance.

Q: Does the SML_190_BTP maintain the same regulatory compliance as the VCC 4336?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory continuity is maintained between these components.

Q: What is the significance of the Fresnel ring optical pattern in the SML_190_BTP?

A: The Fresnel ring pattern in the SML_190_BTP produces a different light distribution characteristic compared to the wide pattern in the VCC 4336. The specific optical performance impact depends on the LED source characteristics and application viewing angle requirements.

Q: Is the 0.07mm lens diameter increase from 4.83mm to 4.9mm significant?

A: The dimensional increase must be evaluated within the mechanical envelope constraints of the specific application. In applications with tight tolerance requirements or specific mounting cavity dimensions, this variance may require design verification.

Q: What packaging options are available for the SML_190_BTP?

A: The SML_190_BTP is supplied in bulk packaging, with documented inventory of 1696 pieces available. Packaging configuration should be confirmed against procurement requirements.
