Substitute Part Grouping Explanation

The TSAL6400 qualifies as a direct substitute for the TSAL7600 based on the following alignment of critical electrical and mechanical parameters:

• Wavelength: Both operate at 940nm, ensuring compatibility with existing receiver circuits and optical system designs
• Forward Current Rating: Both rated at 100mA maximum DC forward current
• Forward Voltage: Both specify 1.35V typical forward voltage, maintaining circuit design compatibility
• Operating Temperature Range: Both support -40°C ~ 85°C operating range
• Mounting Type & Package: Both use through-hole radial mounting in 5mm diameter (T 1 3/4) packages
• RoHS Compliance: Both meet ROHS3 compliance requirements

The TSAL6400 is an active product with higher radiant intensity (25mW/sr @ 100mA versus 15mW/sr @ 100mA) and a narrower viewing angle (50° versus 60°), representing an enhanced specification variant suitable for applications requiring increased optical output within a more focused beam pattern.

Parameter Comparison

Engineering Selection Recommendations

The TSAL6400 is the recommended substitute for the obsolete TSAL7600. Both components maintain identical electrical specifications for wavelength, forward current, and forward voltage, ensuring direct circuit compatibility. The TSAL6400 is an active product with current manufacturing support and supply availability, eliminating obsolescence risk.

The TSAL6400 provides enhanced radiant intensity (25mW/sr versus 15mW/sr), which represents improved optical output performance. The narrower viewing angle (50° versus 60°) concentrates this output within a tighter beam pattern. These specification differences are advantageous for applications requiring higher signal strength or more directional optical transmission.

Both components meet ROHS3 and REACH compliance requirements, supporting modern regulatory standards for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the TSAL6400 be used as a direct replacement for the TSAL7600 in existing circuit designs?

A: Yes. Both components share identical wavelength (940nm), forward current rating (100mA), forward voltage (1.35V), operating temperature range (-40°C ~ 85°C), and package configuration (radial, 5mm through-hole). Circuit-level compatibility is maintained.

Q: What are the differences between the TSAL7600 and TSAL6400?

A: The primary differences are product status and optical output characteristics. The TSAL7600 is obsolete; the TSAL6400 is active. The TSAL6400 provides higher radiant intensity (25mW/sr versus 15mW/sr @ 100mA) and a narrower viewing angle (50° versus 60°). These represent performance enhancements rather than incompatibilities.

Q: Will the increased radiant intensity of the TSAL6400 affect my circuit design?

A: The increased radiant intensity is an enhancement that improves optical signal strength. Receiver circuits designed for the TSAL7600 will function with the TSAL6400. If your design includes automatic gain control or receiver sensitivity adjustment, the higher output may require recalibration to maintain optimal signal levels.

Q: Are both components available in the same packaging?

A: Yes. Both the TSAL7600 and TSAL6400 use radial, 5mm diameter (T 1 3/4) through-hole packages, ensuring identical mechanical fit and PCB mounting compatibility.

Q: What compliance certifications apply to both parts?

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