Key Parameters

Substitute Part Grouping Explanation

The 76383-322LF qualifies as a direct substitute based on identical electrical and mechanical parameters: connector type, contact configuration, position count, pitch spacing, mounting orientation, shrouding design, and termination method are unchanged. Both parts belong to the Amphenol ICC Dubox™ series and maintain the same contact material, insulation composition, and flammability rating.

The substitution is valid across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Position Configuration: 44 positions, 2 rows
• Pitch: 0.100" (2.54mm) mating and row spacing
• Mounting: Through Hole, Right Angle
• Shrouding: Shrouded - 2 Wall
• Termination: Solder
• Contact Material: Phosphor Bronze
• Insulation Material: Polyester, Glass Filled
• Flammability: UL94 V-0

Parameter Comparison

Engineering Selection Recommendations

The 76383-322LF is the active equivalent for the obsolete 76383-322. Selection between these parts should be based on regulatory and compliance requirements:

The 76383-322LF is RoHS compliant and REACH affected, making it suitable for applications subject to European Union environmental directives. The 76383-322 is RoHS non-compliant and REACH unaffected, appropriate only for legacy systems or applications exempt from these regulations.

Both parts maintain identical mechanical and electrical interfaces. The contact finish on the post differs: the 76383-322 uses tin-lead while the 76383-322LF uses tin. This difference reflects the RoHS compliance transition and does not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 76383-322LF directly replace the 76383-322 in existing designs?

A: Yes, the 76383-322LF is mechanically and electrically compatible. Both connectors share identical pitch, position count, mounting type, and contact configuration. The primary consideration is regulatory compliance: the 76383-322LF is RoHS compliant, while the 76383-322 is not.

Q: What is the difference between the tin-lead and tin post finishes?

A: The 76383-322 uses tin-lead post finish (150.0µin / 3.81µm thickness), while the 76383-322LF uses tin post finish (78.7µin / 2.00µm thickness). Both finishes provide adequate solder joint reliability for standard through-hole applications. The tin finish in the 76383-322LF reflects RoHS compliance requirements.

Q: Are there any packaging differences between these parts?

A: The 76383-322LF is supplied in tube packaging, while the 76383-322 packaging is not specified. This affects handling and storage but does not impact electrical or mechanical performance.

Q: What is the operating temperature range for these connectors?

A: The 76383-322LF operates from -40°C to 125°C. Operating temperature for the 76383-322 is not specified in the available data.

Q: What current rating applies to these connectors?

A: The 76383-322LF is rated for 3A per contact. Current rating for the 76383-322 is not specified in the available data.

Q: Are both parts suitable for new designs?

A: The 76383-322LF is the appropriate choice for new designs, as it carries active product status and RoHS compliance. The 76383-322 is obsolete and should be used only for legacy system maintenance or replacement applications.
