Equivalent & Substitute Parts for 77319-804-72

Part Overview

The 77319-804-72 is a rectangular connector header manufactured by Amphenol ICC (FCI) from the BERGSTIK® series. This through-hole, right-angle connector features 72 positions at 0.100" (2.54mm) pitch with male pin contacts and board-to-board connectivity. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution for the 77319-804-72 is determined by strict equivalence across the following critical parameters:

• Number of positions: 72
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Connector type: Header
• Contact type: Male pin
• Mounting type: Through hole, right angle
• Termination: Solder
• Style: Board to board
• Shrouding: Unshrouded
• Contact shape: Square
• Insulation material: Thermoplastic
• Material flammability rating: UL94 V-0
• Insulation color: Black

Two substitute parts meet these criteria:

1. 77319-804-72LF (Amphenol ICC / FCI) - Direct manufacturer equivalent with active product status and RoHS compliance
2. 2372-5121-TG (3M) - Cross-manufacturer equivalent from the 2300 series with active product status

Parameter Comparison

Engineering Selection Recommendations

77319-804-72LF is the primary substitute for the obsolete 77319-804-72. Both parts are from the same manufacturer and BERGSTIK® series, ensuring mechanical and electrical compatibility. The 77319-804-72LF carries active product status and RoHS compliance, making it suitable for new designs and applications requiring regulatory adherence. The addition of operating temperature range (-65°C ~ 130°C) and current rating (3A) specifications provides enhanced documentation for the active variant.

2372-5121-TG from 3M serves as a cross-manufacturer alternative when Amphenol ICC components are unavailable. This part maintains all critical dimensional and electrical parameters while offering active product status. The 2300 series connector provides equivalent functionality with glass-filled thermoplastic insulation. Operating temperature range (-55°C ~ 105°C) is narrower than the Amphenol variant, and RoHS compliance status differs; these factors should be evaluated against specific application requirements.

Selection between these substitutes depends on supply availability, regulatory compliance mandates, and operating environment specifications.

Frequently Asked Questions (FAQ)

Q: Can 77319-804-72LF be used as a direct replacement for 77319-804-72?

A: Yes. Both parts share identical connector type, position count, pitch, row spacing, mounting configuration, and contact specifications. The primary difference is product status (active vs. obsolete) and RoHS compliance. Mechanical and electrical compatibility is maintained.

Q: What are the key differences between the Amphenol and 3M substitutes?

A: Both maintain the critical parameters of 72 positions, 2 rows, 0.100" pitch, and right-angle through-hole mounting. Differences include manufacturer series (BERGSTIK® vs. 2300), contact material (Phosphor Bronze vs. Copper Alloy), insulation composition (standard vs. glass-filled thermoplastic), operating temperature range (-65°C to 130°C vs. -55°C to 105°C), and RoHS compliance status.

Q: Does the packaging format affect substitution compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The 77319-804-72LF is available in bulk packaging, while the original part number does not specify packaging. Packaging selection is a procurement consideration independent of functional equivalence.

Q: Are there any contact finish differences that affect performance?

A: The 77319-804-72 and 77319-804-72LF both feature gold mating contact finish with GXT™ specification. The 2372-5121-TG uses standard gold finish without the GXT™ designation. All three parts meet UL94 V-0 flammability requirements. Contact finish differences do not prevent functional substitution in standard applications.

Q: What is the significance of the "LF" designation in 77319-804-72LF?

A: The "LF" suffix indicates lead-free compliance, reflecting RoHS regulatory requirements. This designation distinguishes the active, compliant variant from the obsolete original part number.
