Substitute Part Grouping Explanation

Substitution for the 77319-803-32 is determined by strict equivalence across the following critical parameters:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Number of positions: 32
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole, Right Angle
• Termination: Solder
• Fastening type: Push-Pull
• Contact finish - mating: Gold, GXT™
• Contact material: Phosphor Bronze
• Insulation material: Thermoplastic
• Material flammability rating: UL94 V-0
• Insulation color: Black

The substitute part 77319-803-32LF maintains all these critical parameters, ensuring mechanical and electrical compatibility. The primary distinction is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 77319-803-32LF is the direct substitute for the obsolete 77319-803-32. Both components share identical mechanical and electrical specifications across all critical mating and mounting parameters. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• RoHS compliance aligns with current regulatory requirements for new designs and procurement
• Specified operating temperature range (-65°C ~ 130°C) and current rating (3A) provide documented performance parameters
• Tin finish on post contacts (78.7µin / 2.00µm) complements the gold-plated mating contacts

Selection of the 77319-803-32LF is appropriate for both replacement applications and new designs requiring this connector configuration.

Frequently Asked Questions (FAQ)

Q: Are the 77319-803-32 and 77319-803-32LF mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), contact geometry, and mounting configuration. They are mechanically interchangeable in board-to-board applications.

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

A: The "LF" designation indicates lead-free compliance. The 77319-803-32LF is RoHS compliant, whereas the original 77319-803-32 is RoHS non-compliant.

Q: Can the 77319-803-32LF be used in applications originally designed for the 77319-803-32?

A: Yes. The substitute part maintains all critical electrical and mechanical parameters. The primary difference is regulatory compliance and product status.

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

A: Both parts feature gold-plated mating contacts (15.0µin / 0.38µm). The 77319-803-32LF additionally specifies tin finish on post contacts (78.7µin / 2.00µm), whereas the original part does not specify post contact finish.

Q: Is the 77319-803-32 still available for purchase?

A: The 77319-803-32 is listed as obsolete. The 77319-803-32LF is the active substitute and is the recommended part for procurement.

Q: What packaging options are available?

A: The 77319-803-32LF is supplied in bulk packaging. The original part packaging is not specified.
