Substitute Part Grouping Explanation

The 76383-330LF qualifies as a direct substitute based on the following critical parameters:

Identical connector type, contact type, and position count (60 positions, 2 rows)
Matching pitch specifications (0.100" / 2.54mm mating pitch and row spacing)
Identical mounting configuration (through hole, right angle)
Matching shrouding design (shrouded 2-wall construction)
Identical contact geometry and mating contact length (0.197" / 5.00mm)
Equivalent insulation material and flammability rating (UL94 V-0)
Same series designation (Dubox™)

The primary distinction is product status: 76383-330 is obsolete, while 76383-330LF is active production. The suffix "LF" indicates lead-free compliance in the 76383-330LF variant.

Engineering Selection Recommendations

The 76383-330LF is the direct active equivalent for the obsolete 76383-330. Selection of the 76383-330LF is appropriate for new designs and replacement applications based on the following factors:

All mechanical and electrical mating characteristics are identical, ensuring direct form-fit-function compatibility
The 76383-330LF achieves RoHS compliance, meeting current regulatory requirements for electronic components in most jurisdictions
Active production status ensures long-term availability and supply chain stability
The lead-free post finish (Tin) on the 76383-330LF is compatible with modern soldering processes and environmental standards
Operating temperature range (-40°C ~ 125°C) and current rating (3A) are specified for the active variant, providing documented performance parameters

For applications requiring the original tin-lead post finish or non-compliant status, the 76383-330 remains available in existing inventory (689 pcs), but sourcing is limited to stock depletion.

Frequently Asked Questions (FAQ)

Q: Can the 76383-330LF be used as a direct replacement for the 76383-330?

A: Yes. The 76383-330LF is mechanically and electrically identical to the 76383-330 in all mating and mounting characteristics. The primary differences are product status (active vs. obsolete), RoHS compliance, and post finish material. These differences do not affect form-fit-function compatibility in the connector interface.

Q: What does the "LF" suffix indicate?

A: The "LF" suffix indicates lead-free compliance. The 76383-330LF uses tin-based post finish instead of tin-lead, meeting RoHS and lead-free soldering requirements.

Q: Are there differences in contact finish that affect performance?

A: The mating contact finish is identical (Gold, GXT™ at 30.0µin thickness) for both parts. The post finish differs: 76383-330 uses tin-lead (150.0µin), while 76383-330LF uses tin (78.7µin). Both finishes are suitable for solder termination and do not affect the mating interface performance.

Q: What is the packaging difference?

A: The 76383-330LF is supplied in tube packaging, while packaging information for the 76383-330 is not specified. Tube packaging is standard for active production components and does not affect component functionality.

Q: Is the 76383-330LF suitable for high-temperature applications?

A: The 76383-330LF is rated for -40°C to 125°C operating temperature. Applications requiring operation outside this range require evaluation against specific environmental requirements.

Q: What is the current-carrying capacity?

A: The 76383-330LF is rated at 3A per contact. Total system current capacity depends on the number of loaded positions and application circuit design.
