Key Parameters

Substitute Part Grouping Explanation

Substitution for the MM6605I is based on the following critical parameters:

• Package compatibility: Cylinder (6.4mm Dia) form factor
• Power output: 5mW nominal specification
• Wavelength range: Red spectrum laser diodes (650nm–660nm)
• Regulatory compliance: ECCN EAR99 classification

The MM6505I qualifies as a substitute based on matching package geometry, power output, and regulatory classification. Wavelength variation from 660nm to 650nm represents a shift within the red spectrum suitable for applications tolerant of this spectral difference. Current rating and voltage specifications differ and must be evaluated against circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

The MM6505I is available in active production status with ROHS3 compliance certification, providing supply chain continuity for the obsolete MM6605I. Both components share identical package geometry and power output specifications. The 10nm wavelength difference (660nm to 650nm) and increased current requirement (40mA versus 30mA) require circuit-level evaluation to confirm compatibility with existing driver and optical system designs.

Frequently Asked Questions (FAQ)

Q: Can MM6505I directly replace MM6605I in existing assemblies?

A: Physical package compatibility is confirmed (both use 6.4mm diameter cylinder case). Electrical and optical parameters differ and must be validated against circuit specifications and application requirements before implementation.

Q: What is the wavelength difference impact?

A: The MM6505I operates at 650nm compared to the MM6605I at 660nm. Both wavelengths fall within the red spectrum. Application suitability depends on optical system design and wavelength-dependent performance criteria.

Q: Are there compliance differences between these parts?

A: Both parts carry EAR99 ECCN classification and 8541.41.0000 HTSUS code. The MM6505I includes ROHS3 compliance certification, while the MM6605I status is not specified.

Q: What is the current rating difference?

A: The MM6505I requires 40mA versus 30mA for the MM6605I. Driver circuit design must accommodate this increased current demand.

Q: Is the MM6505I the only substitute available?

A: Based on provided data, MM6505I is the documented substitute for MM6605I from US-Lasers Inc.
