Substitute Part Grouping Explanation

Substitution eligibility for the 76382-304 is determined by the following critical parameters: 4-position count, 2.54mm mating pitch, through-hole right-angle mounting, shrouded construction, solder termination, 3A current rating, and operating temperature range compatibility. Parts meeting these core electrical and mechanical specifications are classified as direct substitutes.

The substitute parts identified fall into two categories:

Category 1: Direct Form-Fit-Function Substitutes

76382-304LF (Amphenol ICC, Dubox™ series)
5-103361-2 (TE Connectivity, AMPMODU Mod II series)

These parts maintain identical position count, pitch, mounting orientation, shrouding type, and current rating as the original 76382-304.

Category 2: Functional Equivalent with Design Differences

77317-112-24LF (Amphenol ICC, BERGSTIK® series)

This part differs in position count (24 vs. 4) and row configuration (2 rows vs. 1 row), making it unsuitable for direct mechanical substitution in existing designs. It is listed as a reference only for applications requiring higher-density interconnection at the same 2.54mm pitch.

Engineering Selection Recommendations

76382-304LF is the primary direct substitute for the obsolete 76382-304. Both parts share identical mechanical dimensions, electrical ratings, and shrouded 4-position configuration. The 76382-304LF is actively manufactured and RoHS Compliant, addressing regulatory requirements that the original part does not meet. The only material difference is the contact finish post composition (Tin vs. Tin-Lead), which does not affect functional compatibility. This part is suitable for direct replacement in existing designs without PCB layout modifications.

5-103361-2 (TE Connectivity AMPMODU Mod II) is an alternative direct substitute meeting the same 4-position, 2.54mm pitch, and 3A current specifications. This part features a different fastening mechanism (Push-Pull vs. Friction Lock) and slightly different contact lengths. The operating temperature range is narrower (-65°C to 105°C vs. -40°C to 125°C), which may be a limiting factor for applications requiring the full original temperature range. This part is ROHS3 Compliant and actively produced. Selection of this part requires verification that the Push-Pull fastening mechanism is compatible with the mating connector design.

77317-112-24LF is not recommended as a direct substitute due to fundamental design differences: 24-position count and 2-row configuration versus the original 4-position, 1-row layout. This part is listed for reference only in applications where higher-density interconnection at 2.54mm pitch is required.

Frequently Asked Questions (FAQ)

Q: Can the 76382-304LF be used as a direct replacement for the 76382-304 in existing designs?

A: Yes. The 76382-304LF maintains identical mechanical and electrical specifications, including 4-position count, 2.54mm pitch, through-hole right-angle mounting, shrouded construction, and 3A current rating. No PCB layout changes are required. The part is actively manufactured and RoHS Compliant.

Q: What is the difference between the Friction Lock and Push-Pull fastening types?

A: Friction Lock fastening (76382-304 and 76382-304LF) relies on mechanical friction to secure the mated connector. Push-Pull fastening (5-103361-2 and 77317-112-24LF) uses a locking mechanism that requires deliberate action to disconnect. The choice depends on the mating connector design and application requirements for connection security.

Q: Why is the 76382-304 listed as obsolete?

A: The original part is no longer in active production. The 76382-304LF, manufactured by the same company in the same series, is the active replacement and is recommended for new designs and ongoing procurement.

Q: Are there temperature range limitations when substituting with the 5-103361-2?

A: The 5-103361-2 operates from -65°C to 105°C, which is narrower than the original 76382-304 range of -40°C to 125°C. Applications requiring operation above 105°C or below -65°C must use the 76382-304LF or original part specifications.

Q: What is the significance of RoHS Compliance for these parts?

A: RoHS Compliance indicates the part meets restrictions on hazardous substances in electrical and electronic equipment. The original 76382-304 is RoHS non-compliant, while both 76382-304LF and 5-103361-2 are RoHS Compliant, making them suitable for applications with regulatory requirements for lead-free and restricted substance compliance.

Q: Can the 77317-112-24LF be used if only 4 positions are needed?

A: The 77317-112-24LF is a 24-position, 2-row connector and is not mechanically compatible with designs requiring a 4-position, 1-row header. It is not suitable for direct substitution and should only be considered for applications requiring higher-density interconnection.

Q: What packaging options are available for these substitute parts?

A: The 76382-304LF is available in Bulk packaging. The 5-103361-2 is supplied in Tube packaging. Packaging selection may affect procurement quantities and handling requirements for manufacturing operations.
