Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLM-650-14-SPA is determined by the following critical parameters:

• Wavelength: 650nm (exact match required)
• Power Output: 2.5mW (exact match required)
• Current Rating: 40mA (exact match required)
• Voltage Input Range: Must accommodate or exceed the 4V requirement

The VLM-650-03 LPA qualifies as a direct substitute based on matching wavelength, power output, and current rating specifications. The substitute part features an expanded voltage input range (2.6V ~ 5V) that encompasses the original 4V specification, providing operational compatibility within the same electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

The VLM-650-03 LPA is the qualified substitute for the obsolete VLM-650-14-SPA. Selection is based on:

• Identical optical and electrical performance specifications (wavelength, power, current)
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance, addressing regulatory requirements not met by the original part
• Voltage input range compatibility with the original 4V specification
• Matching export classification and tariff codes

Frequently Asked Questions (FAQ)

Q: Can the VLM-650-03 LPA directly replace the VLM-650-14-SPA in existing designs?

A: Yes. Both parts share identical wavelength (650nm), power output (2.5mW), and current rating (40mA) specifications. The substitute part's expanded voltage input range (2.6V ~ 5V) is compatible with the original 4V requirement.

Q: What is the primary difference between these two parts?

A: The VLM-650-03 LPA is an active product with ROHS3 compliance, while the VLM-650-14-SPA is obsolete and RoHS non-compliant. Both maintain identical optical and electrical performance parameters.

Q: Are there packaging differences between the main part and substitute?

A: The VLM-650-03 LPA is supplied in bulk packaging, whereas the original part packaging specification is not provided in the technical data.

Q: Do both parts share the same export classification?

A: Yes. Both parts are classified under ECCN EAR99 and HTSUS code 8541.41.0000.
