Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76384-409 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 9 positions in single row
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Mechanical Interface: Shrouded 2-wall design with friction lock fastening
• Contact Geometry: Square contact shape
• Insulation Properties: Thermoplastic, glass-filled material with UL94 V-0 rating

The substitute part 76384-409LF maintains full electrical and mechanical compatibility with the original specification while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The 76384-409LF serves as the direct functional equivalent to the obsolete 76384-409. Both parts share identical electrical and mechanical specifications within the Dubox™ series, ensuring pin-for-pin and footprint compatibility.

Compliance Considerations: The 76384-409LF offers RoHS compliance status, whereas the original 76384-409 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 76384-409LF is the appropriate selection. The substitute part carries REACH Affected status compared to the original's REACH Unaffected designation.

Contact Finish Difference: The 76384-409LF employs pure tin plating (78.7µin / 2.00µm) on both mating and post contacts, replacing the tin-lead finish (150.0µin / 3.81µm) of the original part. This change aligns with lead-free manufacturing standards and does not affect functional compatibility for standard through-hole solder applications.

Product Availability: The 76384-409LF maintains active product status with current inventory availability, whereas the 76384-409 is classified as obsolete. For new designs and ongoing procurement, the 76384-409LF is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Are the 76384-409 and 76384-409LF mechanically interchangeable?

A: Yes. Both parts maintain identical mechanical specifications including 9-position single-row configuration, 0.100" (2.54mm) pitch, shrouded 2-wall design, through-hole mounting, and friction lock fastening. PCB footprints and mating interface dimensions are equivalent.

Q: What is the significance of the "LF" designation in the 76384-409LF part number?

A: The "LF" suffix indicates lead-free construction. The 76384-409LF uses pure tin contact plating instead of the tin-lead finish found in the original 76384-409, aligning with RoHS compliance requirements.

Q: Can the 76384-409LF be used as a direct replacement in existing designs using the 76384-409?

A: Yes, the 76384-409LF is a direct functional replacement. The change from tin-lead to pure tin plating does not affect electrical performance or solder joint reliability in standard through-hole applications. Designs using the original part can transition to the 76384-409LF without modification.

Q: What is the difference in contact finish thickness between these parts?

A: The 76384-409 features 150.0µin (3.81µm) tin-lead plating, while the 76384-409LF has 78.7µin (2.00µm) pure tin plating. Both thicknesses meet industry standards for connector durability and electrical performance.

Q: Why is the 76384-409 classified as obsolete?

A: The original part's obsolete status reflects the industry-wide transition to lead-free and RoHS-compliant components. The 76384-409LF represents the current active equivalent within the Dubox™ series.

Q: Are there any temperature or current rating differences?

A: The 76384-409LF specifies an operating temperature range of -40°C to 125°C and a current rating of 3A. The original 76384-409 does not provide these specifications in the available documentation. For applications requiring defined thermal and current performance, the 76384-409LF provides explicit ratings.

Q: What packaging options are available?

A: The 76384-409LF is supplied in tube packaging. The original 76384-409 packaging specification is not documented.
