Substitute Part Grouping Explanation

Substitution of the 76385-303 with the 76385-303LF is based on electrical and mechanical parameter equivalence within the Dubox™ series. Both parts maintain identical specifications for:

• Connector type, contact type, and pin configuration (6-position, 2-row header)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Shrouding design (Shrouded - 2 Wall)
• Mounting methodology (Through Hole, Solder Termination)
• Contact geometry and material composition (Square, Copper Alloy)
• Insulation material and flammability rating (Thermoplastic Glass Filled, UL94 V-0)
• Base product number (76385)

The 76385-303LF represents the active production equivalent with enhanced compliance status and improved contact finish specifications. The substitution is valid for applications requiring identical mechanical and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 76385-303LF is the direct active equivalent for the obsolete 76385-303. Selection of the 76385-303LF is appropriate for new designs and component replenishment based on the following factors:

Product Status: The 76385-303LF maintains active production status, ensuring long-term availability and supply chain continuity. The 76385-303 is obsolete and subject to inventory depletion.

Compliance and Regulatory Status: The 76385-303LF is RoHS Compliant and REACH Affected, meeting current environmental and regulatory requirements. The 76385-303 is RoHS non-compliant and REACH Unaffected, reflecting legacy compliance standards.

Contact Finish Specifications: The 76385-303LF incorporates GXT™ gold plating technology on mating contacts with tin-only post finish (78.7µin / 2.00µm), eliminating lead content. The 76385-303 uses tin-lead post finish (150.0µin / 3.81µm), which is restricted under RoHS regulations.

Mechanical and Electrical Equivalence: Both parts maintain identical connector geometry, pitch spacing, shrouding design, and mounting methodology. The 76385-303LF provides documented operating temperature range (-40°C ~ 125°C) and current rating (3A), enabling precise application verification.

Packaging Consideration: The 76385-303LF is supplied in bulk packaging, while the 76385-303 was supplied in tube packaging. Procurement processes should account for this packaging difference.

Frequently Asked Questions (FAQ)

Q: Are the 76385-303 and 76385-303LF mechanically interchangeable?

A: Yes. Both parts maintain identical connector geometry, pitch spacing (0.100" / 2.54mm), row configuration (2-row, 6-position), shrouding design (Shrouded - 2 Wall), and through-hole mounting specifications. They are mechanically interchangeable in board-to-cable/wire applications.

Q: What is the primary difference between these two parts?

A: The 76385-303LF is the active production equivalent with RoHS compliance, lead-free contact finish, and documented operating specifications. The 76385-303 is obsolete with legacy tin-lead finish and non-compliant status.

Q: Can I use the 76385-303LF as a direct replacement in existing designs?

A: Yes. The 76385-303LF is electrically and mechanically equivalent to the 76385-303. The lead-free contact finish and RoHS compliance of the 76385-303LF make it suitable for direct substitution in new production and repair applications.

Q: What is the significance of the "LF" designation in the part number?

A: The "LF" suffix indicates lead-free composition, specifically referring to the elimination of lead from the contact finish. This designation aligns with RoHS compliance requirements.

Q: Are there any temperature or current rating differences?

A: The 76385-303LF provides documented specifications: operating temperature range of -40°C ~ 125°C and current rating of 3A. The 76385-303 does not specify these parameters in available documentation. Both parts are suitable for standard low-voltage signal applications within the specified temperature range.

Q: How does the packaging difference affect component selection?

A: The 76385-303 was supplied in tube packaging, while the 76385-303LF is supplied in bulk packaging. This affects procurement quantities and handling procedures but does not impact electrical or mechanical performance.

Q: Is the GXT™ gold plating technology on the 76385-303LF significant?

A: GXT™ represents an enhanced gold plating process on mating contacts. Both parts maintain 30.0µin (0.76µm) gold thickness on mating surfaces. The GXT™ designation indicates improved contact reliability and corrosion resistance characteristics.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage or handling.
