Parameter Comparison

Engineering Selection Recommendations

The Dialight 5640100320F is the direct substitute for the obsolete 5640100320. Both parts share identical electrical specifications, optical characteristics, and mounting configuration. The 5640100320F offers two significant advantages:

1. Active Product Status: The 5640100320F is actively manufactured and supported by Dialight, ensuring long-term availability and supply chain reliability.

2. Regulatory Compliance: The 5640100320F meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. This distinction is critical for applications subject to RoHS directives or customer compliance mandates.

Both parts maintain equivalent MSL ratings, REACH status, and export classification. Selection between these parts should be based on regulatory requirements and supply availability rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Are the 5640100320 and 5640100320F electrically interchangeable?

A: Yes. Both parts operate at identical voltage ratings (2.1V Green, 2.1V Yellow), current ratings (30mA Green, 20mA Yellow), and produce equivalent light output (12.6mcd Green, 10mcd Yellow) with identical viewing angles (60°).

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

A: The 5640100320F is the active production variant with ROHS3 compliance, while the 5640100320 is obsolete and RoHS non-compliant. Functionally and electrically, they are equivalent.

Q: Can the 5640100320F be used as a direct replacement in existing designs?

A: Yes. The 5640100320F maintains the same through-hole, right-angle mounting configuration, diffused lens type, and three-position LED arrangement (Green, Yellow, Blank). No circuit or mechanical modifications are required.

Q: Are there packaging differences between these parts?

A: The 5640100320F is supplied in bulk packaging, whereas the original part packaging specification is not detailed. Confirm packaging requirements with your procurement process.

Q: What compliance certifications apply to both parts?

A: Both parts share REACH Unaffected status and EAR99 export classification. The 5640100320F additionally meets ROHS3 compliance requirements.
