Substitute Part Grouping Explanation

Substitution eligibility for the 76385-403 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (6) and rows (2)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 2 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)
• Contact material (Copper Alloy)
• Insulation material (Thermoplastic, Glass Filled)
• Flammability rating (UL94 V-0)

The direct substitute 76385-403LF maintains identical mechanical and electrical interface specifications while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 76385-403LF is the direct substitute for the obsolete 76385-403. Both components share identical mechanical and electrical interface specifications, ensuring pin-for-pin compatibility in through-hole PCB applications.

The 76385-403LF offers the following advantages:

• Active product status with continuous manufacturing support
• RoHS compliance, meeting current environmental regulations
• Specified operating temperature range (-40°C ~ 125°C) and current rating (3A)
• REACH compliance status for regulated substance management

For applications requiring the 76385-403, the 76385-403LF provides a direct replacement path without design modification. The difference in contact finish (Tin-Lead vs. Tin) and finish thickness reflects modern manufacturing standards while maintaining functional equivalence.

Frequently Asked Questions (FAQ)

Q: Is the 76385-403LF a direct pin-for-pin replacement for the 76385-403?

A: Yes. Both parts maintain identical connector geometry, pitch spacing (0.100" / 2.54mm), position count (6 positions, 2 rows), mounting method (through-hole), and shrouding configuration. PCB layouts and mating connectors require no modification.

Q: What is the difference between the contact finishes?

A: The 76385-403 uses Tin-Lead finish (196.9µin / 5.00µm mating, 150.0µin / 3.81µm post), while the 76385-403LF uses Tin finish (78.7µin / 2.00µm for both mating and post). Both finishes provide equivalent electrical performance and solderability for through-hole applications.

Q: Why is the 76385-403 listed as obsolete?

A: The 76385-403 has been superseded by the 76385-403LF, which offers improved compliance status (RoHS compliant) and active manufacturing support. Amphenol ICC continues to produce the 76385-403LF as the current product offering.

Q: Are there packaging differences between these parts?

A: The 76385-403 packaging is not specified in available documentation. The 76385-403LF is supplied in Bulk packaging. Confirm packaging requirements with your procurement department.

Q: What is the current rating for these connectors?

A: The 76385-403LF is rated for 3A per contact. The 76385-403 current rating is not specified in available documentation.

Q: Can I use the 76385-403LF in existing designs specified for the 76385-403?

A: Yes. The 76385-403LF is a direct functional equivalent. No design changes are required. The improved compliance status (RoHS) and active product availability make it the recommended choice for new and ongoing production.
