Engineering Selection Recommendations

The LTL1CHJSDNN-032A is the direct substitute for the obsolete LTL-1CHY-032A based on the following engineering factors:

Compliance and Regulatory Alignment: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited), ensuring compatibility with existing regulatory requirements and environmental specifications.

Manufacturer and Product Family Continuity: Both components are manufactured by Lite-On Inc. and share the same base product family (LTL-1/LTL1), ensuring design consistency and manufacturing quality standards.

Functional Equivalence: The substitute part provides specified electrical and optical parameters (2.05V forward voltage, 20mA test current, 590nm dominant wavelength, 310mcd brightness) that define yellow LED indication functionality. The diffused lens transparency and through-hole mounting type maintain mechanical and optical compatibility with the original part's intended application.

Supply Chain Availability: The LTL1CHJSDNN-032A is currently active in production with 1115 pieces in stock, providing immediate availability compared to the obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Why is the LTL-1CHY-032A obsolete and what does this mean for my design?

A: The LTL-1CHY-032A has reached end-of-life status and is no longer manufactured. The LTL1CHJSDNN-032A serves as the active production equivalent from the same manufacturer and product family, ensuring continued availability for new designs and production runs.

Q: Are the LTL-1CHY-032A and LTL1CHJSDNN-032A mechanically compatible?

A: Both parts are through-hole mounted yellow diffused LEDs from Lite-On Inc. The substitute part features a 3.10mm diameter round lens with domed top and 5.50mm maximum height. Verify that these physical dimensions align with your PCB layout and mechanical assembly requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the LTL-1CHY-032A and LTL1CHJSDNN-032A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What are the electrical specifications of the substitute part?

A: The LTL1CHJSDNN-032A operates at 2.05V forward voltage with a 20mA test current. The dominant wavelength is 590nm with peak wavelength at 591nm, providing standard yellow LED indication with 310mcd brightness and 45° viewing angle.

Q: Can I use the LTL1CHJSDNN-032A as a direct replacement in existing assemblies?

A: The LTL1CHJSDNN-032A is functionally equivalent and shares the same mounting type (through-hole) and optical characteristics (yellow diffused). Confirm that the specified dimensions (3.10mm diameter, 5.50mm height) and electrical parameters (2.05V, 20mA) are compatible with your circuit design and PCB layout before implementation.

Q: What is the current inventory status for the substitute part?

A: The LTL1CHJSDNN-032A has 1115 pieces in stock as new original components, providing immediate availability for production requirements.
