Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VCLB1104LS-TR are identified based on the following criteria:

Functional Category: Both the main part and substitute must operate as discrete LED indication components in surface-mount device (SMD) packaging.

Manufacturer Consistency: The substitute part VCHB1104LSE-TR is sourced from the same manufacturer (Stanley Electric Co), ensuring design compatibility and performance alignment with the original specification.

Discrete LED Indication Function: The substitute maintains the same functional classification as "LED Indication - Discrete," confirming equivalent operational purpose within electronic assemblies.

Key Differentiators: The substitute part is classified as "LED HIGH BRIGHT SMD," indicating enhanced luminous intensity compared to the standard indication variant. This represents a performance upgrade while maintaining functional compatibility.

Compliance and Environmental Status: Both parts share REACH Unaffected status, confirming equivalent regulatory compliance for international distribution and use.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The VCHB1104LSE-TR is the primary substitute for the VCLB1104LS-TR. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete original.

Compliance Advantage: The substitute part carries ROHS3 Compliant certification, providing enhanced environmental and regulatory compliance for applications requiring adherence to current international standards.

Moisture Handling Consideration: The main part (VCLB1104LS-TR) features MSL 1 (Unlimited moisture sensitivity), while the substitute (VCHB1104LSE-TR) is rated MSL 2A (4 Weeks). This difference requires evaluation based on storage and assembly environment conditions. MSL 2A components require controlled humidity storage and have a 4-week floor life after moisture barrier bag opening.

Performance Upgrade: The substitute part designation as "LED HIGH BRIGHT" indicates increased luminous output. This upgrade is compatible with standard indication circuit designs while providing enhanced visibility.

Inventory Availability: Both parts maintain adequate stock levels (797 Pcs original, 707 Pcs substitute), supporting immediate procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can VCHB1104LSE-TR directly replace VCLB1104LS-TR in existing designs?

A: Yes. Both parts are discrete LED indication components from Stanley Electric Co with identical functional classification. The substitute is electrically and mechanically compatible for direct substitution in standard indication applications.

Q: What is the significance of the "HIGH BRIGHT" designation in the substitute part?

A: The VCHB1104LSE-TR provides increased luminous intensity compared to the standard VCLB1104LS-TR. This enhancement is compatible with existing circuit designs and does not require modification to current limiting resistors or drive circuits in typical indication applications.

Q: How does the MSL rating difference affect component handling?

A: The original part (MSL 1) has unlimited moisture tolerance and requires no special storage precautions. The substitute (MSL 2A) requires storage in moisture barrier packaging and must be used within 4 weeks of bag opening. Assembly processes must account for this 4-week floor life limitation.

Q: Is the substitute part RoHS compliant?

A: Yes. The VCHB1104LSE-TR carries ROHS3 Compliant certification. The original part's RoHS status is not specified in available documentation.

Q: Are there packaging differences between these parts?

A: Both parts are specified as SMD (surface-mount device) components. Detailed package outline information is not provided in the available parameters. Physical package verification is recommended prior to PCB assembly if package-specific footprint data is required.

Q: What is the REACH compliance status for both parts?

A: Both the VCLB1104LS-TR and VCHB1104LSE-TR are REACH Unaffected, confirming equivalent regulatory status for international distribution and use.
