Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLM-650-26-LPA is determined by the following critical parameters:

• Wavelength: 650nm (red laser diode spectrum)
• Power output range: Functional equivalence within laser diode power classifications
• Manufacturer compatibility: Quarton Inc. product line
• Regulatory compliance: ECCN and HTSUS classifications
• Moisture sensitivity: MSL rating compatibility

The VLM-650-27-LPA qualifies as a substitute based on matching wavelength (650nm), identical manufacturer (Quarton Inc.), equivalent regulatory classifications (ECCN EAR99, HTSUS 8541.41.0000), and identical moisture sensitivity level (MSL 1). Power output differs (3mW vs. 5mW), representing a lower-power alternative within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The VLM-650-27-LPA is the designated substitute for the obsolete VLM-650-26-LPA. Both components share identical wavelength specifications (650nm) and regulatory classifications. The VLM-650-27-LPA offers the advantage of active product status, ensuring continued availability and supply chain support. The substitute operates at reduced power output (3mW versus 5mW), which must be evaluated against application requirements. The VLM-650-27-LPA provides ROHS3 compliance, addressing regulatory requirements not met by the original component. Electrical specifications (2.6V ~ 5V input, 40mA current rating) are documented for the substitute, enabling precise circuit integration.

Frequently Asked Questions (FAQ)

Q: Can the VLM-650-27-LPA directly replace the VLM-650-26-LPA?

A: The VLM-650-27-LPA shares the same wavelength (650nm) and manufacturer (Quarton Inc.), making it functionally compatible within the red laser diode category. The primary difference is reduced power output (3mW vs. 5mW). Substitution feasibility depends on whether the application can operate at the lower power specification.

Q: What is the significance of the power difference between these parts?

A: The VLM-650-26-LPA delivers 5mW output, while the VLM-650-27-LPA delivers 3mW. This 2mW reduction represents a 40% decrease in optical power. Applications requiring the full 5mW specification cannot use the substitute without performance degradation.

Q: Are there packaging differences between these laser diodes?

A: The VLM-650-27-LPA is specified as a cylinder package with 12.5mm diameter. The VLM-650-26-LPA package dimensions are not provided in available documentation. Physical compatibility must be confirmed against mechanical mounting requirements.

Q: What is the regulatory status of each component?

A: Both components carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The VLM-650-26-LPA is RoHS non-compliant, while the VLM-650-27-LPA is ROHS3 compliant. Applications subject to RoHS requirements must use the VLM-650-27-LPA.

Q: Why is the original part listed as obsolete?

A: The VLM-650-26-LPA carries obsolete status, indicating discontinued manufacturing and limited availability. The VLM-650-27-LPA maintains active status with documented inventory, ensuring procurement viability for new designs and ongoing support.
