Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VSMS3700-GS08 is determined by the following critical parameters:

• Package Compatibility: 2-PLCC surface mount package required for mechanical and electrical interface compatibility
• Current Rating: 100mA DC forward current maximum
• Viewing Angle: 120° optical field of view
• Operating Temperature Range: -40°C to 85°C
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The VSML3710-GS08 qualifies as a substitute based on matching package type, current rating, viewing angle, temperature range, and compliance certifications. Wavelength variation (940nm vs 950nm) and radiant intensity differences are within the allowable parameter set for this product category and do not preclude substitution in applications where the specific wavelength is not a critical design constraint.

Parameter Comparison

Engineering Selection Recommendations

The VSML3710-GS08 is the designated manufacturer-recommended substitute for the obsolete VSMS3700-GS08. Both components maintain identical mechanical compatibility through the 2-PLCC package specification and equivalent electrical operating parameters including current rating, temperature range, and viewing angle. The substitute part carries Active product status, ensuring continued availability and supply chain support. Both components satisfy ROHS3 compliance and REACH requirements, maintaining regulatory alignment for applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can the VSML3710-GS08 be used as a direct replacement for the VSMS3700-GS08?

A: Yes. Both components share identical package type (2-PLCC), current rating (100mA), viewing angle (120°), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3, REACH unaffected). The substitute part is manufacturer-recommended.

Q: What are the differences between these two parts?

A: The primary differences are wavelength (950nm vs 940nm), forward voltage (1.3V vs 1.35V typical), and radiant intensity (1.6mW/sr vs 4mW/sr @ 100mA). The VSML3710-GS08 provides higher radiant intensity output.

Q: Does the wavelength difference affect compatibility?

A: Wavelength compatibility depends on application-specific requirements. Both 940nm and 950nm operate in the near-infrared spectrum. Applications with wavelength-dependent optical filters or detectors require evaluation of the 10nm difference.

Q: Are there packaging differences between these parts?

A: The main part uses Cut Tape (CT) & Digi-Reel® packaging, while the substitute uses Tape & Reel (TR) packaging. Both are suitable for surface mount assembly processes.

Q: What is the product status significance?

A: The VSMS3700-GS08 is Obsolete, indicating discontinued production. The VSML3710-GS08 is Active, ensuring ongoing availability and manufacturer support for new designs and production runs.
