Key Parameters

Substitute Part Grouping Explanation

The 77319-804-36LF qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Identical connector type (Header, Breakaway)
• Identical contact type (Male Pin)
• Identical number of positions (36) and row configuration (2 rows)
• Identical pitch specifications (0.100" / 2.54mm mating pitch and row spacing)
• Identical mounting type (Through Hole, Right Angle)
• Identical termination method (Solder)
• Identical contact shape (Square) and material (Phosphor Bronze)
• Identical insulation material (Thermoplastic) and color (Black)
• Identical flammability rating (UL94 V-0)

The 77319-804-36LF represents the active production equivalent within the same BERGSTIK® series, with the "LF" suffix indicating lead-free compliance.

Parameter Comparison

Engineering Selection Recommendations

The 77319-804-36LF is the appropriate substitute for the obsolete 77319-804-36. Both parts maintain identical mechanical and electrical interface specifications, ensuring direct compatibility in board-to-board connector applications.

The primary distinction is product status and regulatory compliance. The 77319-804-36LF is an active production part with RoHS compliance, whereas the original 77319-804-36 is obsolete and RoHS non-compliant. For new designs or component replenishment, the 77319-804-36LF is the specified equivalent.

Both parts carry UL94 V-0 flammability certification and are manufactured within the same BERGSTIK® series by Amphenol ICC (FCI), ensuring consistent quality and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 77319-804-36LF be used as a direct replacement for the 77319-804-36?

A: Yes. Both parts share identical connector type, contact configuration, pitch specifications, mounting method, and termination characteristics. The 77319-804-36LF is the active production equivalent.

Q: What does the "LF" suffix indicate?

A: The "LF" designation indicates lead-free compliance, reflecting the part's RoHS compliance status. The 77319-804-36 is RoHS non-compliant, while the 77319-804-36LF is RoHS compliant.

Q: Are there differences in contact finish between these parts?

A: Both parts feature gold-plated mating contacts with GXT™ finish at 15.0µin (0.38µm) thickness. The 77319-804-36LF includes tin finish on the post contacts at 78.7µin (2.00µm) thickness, whereas the original part does not specify post contact finish.

Q: What is the pitch specification for this connector?

A: The mating pitch is 0.100" (2.54mm), with row spacing also at 0.100" (2.54mm). This is a standard spacing for rectangular header connectors in the 0.100" pitch family.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both parts are designed for through-hole, right-angle mounting with solder termination, making them suitable for standard PCB assembly processes.

Q: What is the position count and row configuration?

A: Both parts feature 36 total positions arranged in 2 rows, providing a 18-position-per-row configuration at 0.100" pitch.
