Parameter Comparison

Engineering Selection Recommendations

The 76383-413LF is the direct active equivalent for the obsolete 76383-413. Selection of the 76383-413LF is supported by the following factors:

• Identical mechanical interface: All dimensional, pitch, and mounting specifications are identical, ensuring direct PCB compatibility without layout modifications.
• Identical electrical interface: Contact configuration, material composition, and fastening mechanism are unchanged.
• Improved compliance status: The 76383-413LF is RoHS Compliant and carries active product status, whereas the 76383-413 is RoHS non-compliant and obsolete.
• Lead-free contact finish: The transition from Tin-Lead to Tin finish aligns with modern manufacturing and environmental standards while maintaining equivalent electrical performance.
• Specified operating parameters: The 76383-413LF provides documented operating temperature range (-40°C ~ 125°C) and current rating (3A), enabling complete system design validation.

For new designs or component replenishment, the 76383-413LF is the appropriate selection. Existing assemblies using the 76383-413 may be transitioned to the 76383-413LF without design changes.

Frequently Asked Questions (FAQ)

Q: Can the 76383-413LF be used as a direct replacement for the 76383-413 in existing designs?

A: Yes. The 76383-413LF maintains identical mechanical and electrical interface specifications. No PCB layout, connector housing, or mating component modifications are required. The primary difference is the lead-free contact finish and active product status.

Q: What is the significance of the "LF" designation in the part number?

A: The "LF" suffix indicates lead-free contact finish. The 76383-413LF uses Tin plating instead of Tin-Lead plating on both mating and post contacts, meeting RoHS compliance requirements.

Q: Are there any performance differences between the Tin-Lead and Tin contact finishes?

A: Both finishes are suitable for the specified electrical and mechanical requirements. The Tin finish in the 76383-413LF provides equivalent contact reliability and conductivity for this connector application.

Q: What is the packaging difference between these parts?

A: The 76383-413 packaging is not specified in the available data. The 76383-413LF is supplied in Tube packaging, which is standard for high-volume connector distribution.

Q: Why is the 76383-413 classified as obsolete?

A: The 76383-413 has been superseded by the 76383-413LF. Amphenol ICC has transitioned this product line to lead-free variants to meet regulatory compliance standards and modern manufacturing requirements.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: What compliance certifications apply to the 76383-413LF?

A: The 76383-413LF is RoHS Compliant and REACH Affected. Both parts carry UL94 V-0 material flammability rating and are classified under ECCN EAR99 for export purposes.
