Key Parameters

Substitute Part Grouping Explanation

Substitution of the PLT5 450B is based on strict equivalence across all critical electrical and optical parameters. The substitute part PLT5 450GB maintains identical specifications for wavelength (450nm), optical power output (120mW), input voltage (5.2V), and operating current (145mA). Both parts utilize the same TO-56-3 Lens Top Metal Can package, ensuring mechanical and thermal compatibility. The substitution is valid because the substitute part meets or exceeds all compliance requirements (ROHS3 Compliant, REACH Unaffected) and maintains the same moisture sensitivity classification. The primary distinction is product status: PLT5 450B is Obsolete while PLT5 450GB is Active, providing improved long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The PLT5 450GB serves as the direct equivalent for the obsolete PLT5 450B. Selection of the substitute part is appropriate for all applications requiring a 450nm blue laser diode with 120mW output power in TO-56-3 packaging. Both parts carry identical RoHS3 compliance certification and REACH Unaffected status, ensuring regulatory alignment across manufacturing jurisdictions. The PLT5 450GB is the recommended selection for new designs and replacement applications due to its Active product status, which provides assured long-term availability and manufacturing support from ams-OSRAM USA INC. No electrical, optical, or mechanical redesign is required when transitioning from PLT5 450B to PLT5 450GB.
