Key Parameters

Substitute Part Grouping Explanation

The VLM-650-27-LPA qualifies as a substitute based on the following critical parameters:

• Wavelength: 650nm (identical)
• Power Output: 3mW (identical)
• Current Rating: 40mA (identical)
• Package / Case: Cylinder (12.5mm Dia) (mechanically similar, minor diameter increase)
• Voltage - Input: 2.6V ~ 5V (encompasses the 4V requirement of the original part)

The VLM-650-27-LPA maintains functional equivalence across all primary electrical specifications while offering improved voltage tolerance and active product status.

Parameter Comparison

Engineering Selection Recommendations

The VLM-650-27-LPA is the designated substitute for the obsolete VLM-650-17-LPA. Selection is based on:

• Electrical parameter equivalence across wavelength, power output, and current rating
• Voltage input specification of 2.6V ~ 5V provides operational compatibility with the original 4V requirement
• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance addresses regulatory requirements not met by the original part
• Cylindrical package geometry remains consistent with minor diameter tolerance (12.0mm to 12.5mm)

Frequently Asked Questions (FAQ)

Q: Can the VLM-650-27-LPA directly replace the VLM-650-17-LPA?

A: Yes. Both components share identical wavelength (650nm), power output (3mW), and current rating (40mA) specifications. The voltage input range of the VLM-650-27-LPA (2.6V ~ 5V) encompasses the 4V requirement of the original part. The cylindrical package diameter increases from 12.0mm to 12.5mm, requiring mechanical fit verification in the application.

Q: What is the significance of the voltage input difference?

A: The VLM-650-17-LPA operates at a fixed 4V input. The VLM-650-27-LPA accepts a voltage range of 2.6V ~ 5V, providing greater operational flexibility while maintaining compatibility with the original 4V specification.

Q: Does the package diameter change affect compatibility?

A: The package diameter increases from 12.0mm to 12.5mm. Mechanical fit must be verified in the specific application. If the mounting cavity or socket is designed for 12.0mm diameter components, the 0.5mm increase may require mechanical accommodation.

Q: What is the impact of RoHS compliance differences?

A: The VLM-650-17-LPA is RoHS non-compliant, while the VLM-650-27-LPA is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the VLM-650-27-LPA provides regulatory alignment.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The VLM-650-27-LPA represents the active equivalent within the Quarton Inc. VLM-650 series, ensuring continued component availability.
