Key Parameters

Substitute Part Grouping Explanation

The VLM-650-02 LPA qualifies as a direct substitute based on the following matching parameters:

• Wavelength: 650nm (identical)
• Power Output: 3mW (identical)
• Current Rating: 40mA (identical)
• Package Type: Cylinder (10.5mm Dia) (identical)
• Manufacturer: Quarton Inc. (same manufacturer)

The VLM-650-02 LPA operates within an expanded voltage range of 2.6V to 5V, which encompasses the original 3V to 5V specification. This extended lower voltage limit provides additional operational flexibility while maintaining full compatibility with systems designed for the VLM-650-09-LPT.

Parameter Comparison

Engineering Selection Recommendations

The VLM-650-02 LPA is the qualified substitute for the obsolete VLM-650-09-LPT. Key selection factors include:

• The substitute maintains identical optical and electrical specifications across wavelength, power output, current rating, and mechanical form factor
• The VLM-650-02 LPA is currently in active production status, ensuring availability for procurement and supply chain continuity
• The substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant, providing environmental and regulatory advantages for new designs and system updates
• The expanded voltage operating range (2.6V to 5V) of the substitute provides additional design margin and operational flexibility

Frequently Asked Questions (FAQ)

Q: Can the VLM-650-02 LPA be used as a direct replacement for the VLM-650-09-LPT?

A: Yes. Both devices share identical wavelength (650nm), power output (3mW), current rating (40mA), and mechanical package (10.5mm diameter cylinder). The substitute operates across a wider voltage range that fully encompasses the original specification.

Q: What is the significance of the expanded voltage range in the VLM-650-02 LPA?

A: The VLM-650-02 LPA operates from 2.6V to 5V, compared to the original 3V to 5V range. This extended lower voltage limit allows operation in systems with lower supply voltages while maintaining full compatibility with designs specified for 3V to 5V operation.

Q: Why is RoHS compliance important when selecting a substitute?

A: The VLM-650-02 LPA achieves ROHS3 compliance, whereas the VLM-650-09-LPT is RoHS non-compliant. For new designs, system updates, and applications subject to environmental regulations, the compliant substitute is the appropriate choice.

Q: Are there any mechanical or dimensional differences between these parts?

A: No. Both parts use identical 10.5mm diameter cylinder packaging, ensuring mechanical compatibility in existing mechanical assemblies and mounting configurations.

Q: What is the availability status of each part?

A: The VLM-650-09-LPT is obsolete and no longer in active production. The VLM-650-02 LPA is in active production status with current inventory availability.
