Key Parameters

Substitute Part Grouping Explanation

The 76385-417LF serves as a direct functional equivalent to the 76385-417. Substitution eligibility is determined by the following critical parameters that must remain constant:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (34)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 2 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Insulation material (Thermoplastic, Glass Filled)
• Flammability rating (UL94 V-0)
• Fastening type (Friction Lock)

The 76385-417LF maintains all these critical parameters, establishing it as a valid substitute. Differences in contact finish composition, finish thickness, insulation color, and compliance status do not affect mechanical or electrical interchangeability for standard through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The 76385-417LF is the appropriate substitute for the obsolete 76385-417 based on the following factors:

Product Status: The 76385-417LF maintains active production status, ensuring long-term availability and supply chain continuity. The original 76385-417 is classified as obsolete, making the LF variant the designated replacement.

Compliance and Certifications: The 76385-417LF achieves RoHS compliance, meeting current regulatory requirements for new designs and manufacturing. The original part is RoHS non-compliant. Both parts maintain UL94 V-0 flammability certification and share identical mechanical and electrical interface specifications.

Mechanical and Electrical Interchangeability: All critical dimensional parameters, contact configurations, and mounting specifications are identical between the two parts. The 76385-417LF provides specified operating temperature range (-40°C ~ 125°C) and current rating (3A), whereas the original part does not document these parameters.

Contact Finish Differences: The 76385-417LF uses pure tin plating (2.00µm thickness) on both mating and post contacts, replacing the tin-lead finish of the original part. This change aligns with RoHS compliance requirements and does not affect mechanical interchangeability in standard through-hole applications.

For new designs and production applications, the 76385-417LF is the specified equivalent. For legacy system maintenance where the original 76385-417 is currently installed, the 76385-417LF provides direct functional replacement without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the 76385-417LF be used as a direct replacement for the 76385-417 in existing assemblies?

A: Yes. The 76385-417LF maintains identical mechanical dimensions, contact pitch, row spacing, mounting type, and electrical interface specifications. No PCB redesign or connector housing modifications are required.

Q: What is the significance of the "LF" suffix in the part number 76385-417LF?

A: The "LF" designation indicates lead-free construction, reflecting the transition from tin-lead plating to pure tin plating. This change ensures compliance with RoHS regulations while maintaining functional equivalence.

Q: Are there any thermal or electrical performance differences between these parts?

A: The 76385-417LF provides documented operating temperature range (-40°C ~ 125°C) and current rating (3A). The original 76385-417 does not specify these parameters. Both parts are constructed from identical materials and maintain the same contact geometry, indicating equivalent thermal and electrical performance within the specified operating range.

Q: What packaging options are available for the 76385-417LF?

A: The 76385-417LF is supplied in tube packaging. Verify packaging requirements for your procurement process.

Q: Does the change from tin-lead to tin plating affect solder joint reliability?

A: Both contact finishes are suitable for solder termination. The tin finish on the 76385-417LF is compatible with standard lead-free and lead-containing solder processes used in through-hole assembly.

Q: Are both parts certified to the same flammability standards?

A: Yes. Both the 76385-417 and 76385-417LF maintain UL94 V-0 material flammability certification.

Q: What is the inventory status for these parts?

A: The 76385-417 (obsolete) has 667 pieces in stock. The 76385-417LF (active) has 793 pieces in stock. For new production, source the 76385-417LF to ensure continued availability.
