Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 76383-402 is based on strict equivalence of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count and row configuration (4 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting style (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 2 Wall)
• Termination method (Solder)
• Fastening mechanism (Friction Lock)
• Contact material (Phosphor Bronze)
• Insulation material (Polyester, Glass Filled)
• Flammability rating (UL94 V-0)

The substitute part 76383-402LF maintains all these core parameters while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 76383-402LF serves as the direct active equivalent to the obsolete 76383-402. Both parts share identical mechanical and electrical interface specifications, ensuring form-fit-function compatibility.

Key distinctions between the parts are:

• The 76383-402LF carries active product status, ensuring long-term availability and manufacturing support.
• The 76383-402LF is RoHS compliant, meeting current regulatory requirements for electronic components in most markets.
• The 76383-402LF features lead-free tin plating (Tin) versus the tin-lead finish of the original part, reducing contact finish thickness from 150.0µin to 78.7µin while maintaining electrical performance.
• The 76383-402LF provides specified operating temperature range (-40°C ~ 125°C) and current rating (3A), enabling complete electrical characterization for design validation.

For new designs or component refresh cycles, the 76383-402LF is the appropriate selection. For legacy systems requiring exact historical equivalence, the mechanical and electrical interface remains unchanged.

Frequently Asked Questions (FAQ)

Q: Are the 76383-402 and 76383-402LF mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.100" / 2.54mm), row spacing, mounting type (through-hole right-angle), shrouding configuration, and contact geometry. PCB footprints and mating connector interfaces are identical.

Q: What is the difference between the contact finishes?

A: The 76383-402 uses tin-lead plating at 150.0µin thickness. The 76383-402LF uses lead-free tin plating at 78.7µin thickness. Both finishes provide equivalent electrical conductivity and contact reliability for standard applications. The lead-free finish aligns with RoHS compliance requirements.

Q: Why is the 76383-402 listed as obsolete?

A: The original part number reflects legacy manufacturing and regulatory status. The 76383-402LF represents the current active production equivalent, incorporating modern lead-free plating and RoHS compliance.

Q: Can the 76383-402LF be used in applications originally designed for the 76383-402?

A: Yes. The electrical and mechanical specifications are equivalent. The 76383-402LF provides additional performance data (operating temperature: -40°C ~ 125°C; current rating: 3A) that supports design validation for the original application parameters.

Q: What packaging is available for the 76383-402LF?

A: The 76383-402LF is supplied in bulk packaging, with 5837 pieces currently in stock.

Q: Are there any compliance differences between these parts?

A: The 76383-402LF is RoHS compliant and REACH affected, reflecting current regulatory frameworks. The 76383-402 is RoHS non-compliant and REACH unaffected, reflecting its legacy status. Both parts carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.
