VOL6405I Equivalent & Substitute Parts

Part Overview

The VOL6405I is a laser diode operating at 640nm wavelength with 4.8mW output power and 70mA current rating in a 10.4mm diameter cylinder package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The primary reason for identifying alternatives is the obsolete product status, which restricts availability through standard distribution channels. Substitute parts must maintain compatibility across the critical electrical and mechanical parameters that define this laser diode's functional role.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VOL6405I is determined by the following parameters:

• Current Rating: Must match 70mA
• Power Output: Must match 4.8mW
• Package Type: Must match Cylinder (10.4mm Dia)
• Wavelength: Primary specification at 640nm; minor wavelength variations within the red laser spectrum may be acceptable depending on application requirements

The VOL6355I qualifies as a substitute based on matching current rating (70mA), power output (4.8mW), and package configuration (Cylinder 10.4mm Dia). The wavelength differs at 635nm versus the original 640nm specification.

Parameter Comparison

Engineering Selection Recommendations

The VOL6355I is available as an active product with ROHS3 compliance certification, providing a path forward from the obsolete VOL6405I. Both components share identical electrical specifications (70mA, 4.8mW) and mechanical packaging (Cylinder 10.4mm Dia), ensuring form-factor compatibility.

The wavelength difference of 5nm (640nm to 635nm) represents the primary technical distinction. Selection between these parts depends on whether the application can accommodate operation within the 635nm to 640nm range of the red laser spectrum.

Frequently Asked Questions (FAQ)

Q: Can VOL6355I directly replace VOL6405I in existing designs?

A: Direct replacement is possible from an electrical and mechanical standpoint. Both components operate at 70mA with 4.8mW output in identical 10.4mm cylinder packages. The 5nm wavelength difference (635nm vs 640nm) must be evaluated against specific application requirements.

Q: What is the significance of the wavelength difference?

A: The VOL6405I operates at 640nm while the VOL6355I operates at 635nm. Both fall within the red laser spectrum. Applications sensitive to specific wavelength performance must confirm compatibility within this 5nm variance.

Q: Why is VOL6405I listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by US-Lasers Inc. The VOL6355I, with active product status, represents the current alternative for equivalent laser diode functionality.

Q: Are there packaging differences between these parts?

A: No. Both the VOL6405I and VOL6355I use identical Cylinder (10.4mm Dia) packaging, ensuring mechanical compatibility in existing mechanical assemblies and sockets.

Q: What compliance certifications apply to the substitute?

A: The VOL6355I carries ROHS3 compliance certification. This environmental compliance status should be verified against system-level requirements.
