Parameter Comparison

Engineering Selection Recommendations

Both LTL1CHUBJ-UA and LTL1CHUBJS-UA are direct parametric equivalents to the obsolete LTL1CHUBJS. Selection between these active alternatives should be based on:

• Product Status: Both substitute parts maintain active manufacturing status, ensuring long-term availability and supply chain continuity.
• Compliance: All three parts maintain ROHS3 compliance, satisfying environmental and regulatory requirements.
• Inventory Availability: LTL1CHUBJS-UA offers 788 pieces in stock, while LTL1CHUBJ-UA provides 688 pieces, both supporting immediate procurement needs.

For applications currently using LTL1CHUBJS, either substitute part provides direct functional and mechanical compatibility without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can LTL1CHUBJ-UA and LTL1CHUBJS-UA be used interchangeably with LTL1CHUBJS?

A: Yes. Both substitute parts maintain identical electrical parameters (3.8V forward voltage, 20mA test current, 25mcd brightness), optical specifications (466nm dominant wavelength, 60° viewing angle, diffused lens), and mechanical dimensions (3.10mm lens diameter, 5.20mm maximum height, radial through-hole mounting). Direct substitution is supported without circuit modification.

Q: What is the difference between LTL1CHUBJ-UA and LTL1CHUBJS-UA?

A: Both parts are parametrically identical across all electrical, optical, and mechanical specifications. The difference lies in part number designation only. Both are active products manufactured by Lite-On Inc. with current inventory availability.

Q: Why is the original LTL1CHUBJS classified as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Lite-On Inc. The active equivalent parts LTL1CHUBJ-UA and LTL1CHUBJS-UA provide continued access to the same functional specification through current production lines.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts maintain identical ROHS3 compliance status, ECCN classification (EAR99), and HTSUS code (8541.41.0000), ensuring regulatory equivalence for procurement and deployment.

Q: Can these parts be used in new designs?

A: Yes. The active substitute parts LTL1CHUBJ-UA and LTL1CHUBJS-UA are suitable for new design implementations. Their active product status ensures manufacturing availability and supply chain support for production volumes.
