Parameter Comparison

Engineering Selection Recommendations

The LT Y1SG-BACB-35-1-20-R18-Z serves as the active equivalent for the obsolete LT Y87S-P2R1-35-0-10-R18-Z. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments.

Selection Basis:

The substitute part is classified as active product status, ensuring ongoing availability and manufacturing support from ams-OSRAM USA INC. The obsolete status of the original part necessitates transition to the substitute for new designs and production continuity.

Both components share identical viewing angle (120°), mounting configuration (Surface Mount, Right Angle), and 2-SMD package architecture. The substitute operates at lower forward voltage (2.85V versus 3.4V) and higher test current (20mA versus 10mA), delivering significantly higher luminous intensity (3150mcd versus 98mcd).

Physical dimensions differ: the substitute measures 2.45mm L x 1.20mm W with 0.90mm maximum height, compared to the original 2.20mm L x 1.20mm W with 1.20mm maximum height. Lead type transitions from flat lead to J-lead configuration. These dimensional and lead-type differences require PCB layout and footprint verification during design transition.

Wavelength-dominant specification shifts from 528nm to 523nm, representing a 5nm variation within the green spectrum range.

Frequently Asked Questions (FAQ)

Q: Can the LT Y1SG-BACB-35-1-20-R18-Z directly replace the LT Y87S-P2R1-35-0-10-R18-Z without circuit modifications?

A: Direct replacement requires circuit evaluation. The substitute operates at 2.85V forward voltage versus 3.4V, and requires 20mA test current versus 10mA. Forward voltage reduction of 0.55V and current increase of 10mA necessitate driver circuit and current-limiting resistor recalculation. PCB footprint changes due to dimensional differences and J-lead versus flat-lead configuration require layout verification.

Q: What are the key differences in optical performance?

A: The substitute delivers 3150mcd compared to the original 98mcd, representing a 32-fold increase in luminous intensity. Both components maintain 120° viewing angle. Wavelength-dominant shifts from 528nm to 523nm. The higher luminous intensity may require optical design adjustment if brightness control is critical to the application.

Q: Are both parts compliant with current regulatory standards?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the product status difference?

A: The original part is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute is active product status, ensuring ongoing manufacturing support, availability, and supply chain continuity from ams-OSRAM USA INC.

Q: How do the package differences affect PCB design?

A: The original part uses 2-SMD flat lead configuration measuring 2.20mm L x 1.20mm W with 1.20mm maximum height. The substitute uses 2-SMD J-lead configuration measuring 2.45mm L x 1.20mm W with 0.90mm maximum height. These differences require footprint redesign, solder pad adjustment, and clearance verification for the J-lead geometry.

Q: What moisture sensitivity level applies to each part?

A: The original part specifies MSL 2 (1 Year), while the substitute specifies MSL 4 (72 Hours). The substitute requires more stringent moisture control during storage and handling, with a 72-hour floor life limitation after moisture exposure.
