Amphenol ICC 77311-118-07 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77311-118-07 is a rectangular connector header in the BERGSTIK® series, designed for through-hole board-to-board applications. This 7-position, single-row connector operates at a 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts and tin-lead post finishes. The part maintains Active product status and is widely used in applications requiring reliable solder-terminated connections with push-pull fastening.

Substitute parts are identified when they maintain electrical and mechanical compatibility across critical parameters including connector type, pitch, position count, contact material, and termination method, while potentially offering improvements in compliance status or environmental ratings.

• Connector Type: Header (identical)
• Contact Type: Male Pin (identical)
• Number of Positions: 7 (identical)
• Pitch - Mating: 0.100" (2.54mm) (identical)
• Mounting Type: Through Hole (identical)
• Termination: Solder (identical)
• Contact Material: Phosphor Bronze (identical)
• Insulation Material: Thermoplastic (identical)
• Material Flammability Rating: UL94 V-0 (identical)
• Insulation Color: Black (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The 77311-118-07LF variant differs in RoHS compliance status (RoHS Compliant versus non-compliant) and includes additional environmental specifications not present in the base part, making it suitable for applications with stricter regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

The 77311-118-07LF serves as the primary substitute for the 77311-118-07 in applications where RoHS compliance is required. Both parts maintain identical mechanical and electrical interface specifications, ensuring direct compatibility in board-to-board through-hole applications.

The 77311-118-07LF provides additional value through RoHS Compliant status and REACH Unaffected designation, making it suitable for regulated markets and applications subject to environmental compliance requirements. The LF variant also specifies operating temperature range (-65°C ~ 125°C) and current rating (3A per Contact), providing explicit environmental performance data.

The primary difference in post finish composition (Tin-Lead versus Tin) reflects the RoHS compliance transition. Both finishes are compatible with standard solder assembly processes and provide equivalent electrical performance for the specified application.

Frequently Asked Questions (FAQ)

Q: Are the 77311-118-07 and 77311-118-07LF mechanically interchangeable?

A: Yes. Both parts share identical connector type, pitch (0.100" / 2.54mm), position count (7), mounting method (through-hole), and contact material (Phosphor Bronze). They are mechanically and electrically interchangeable in board-to-board applications.

Q: What is the primary difference between these two part numbers?

A: The 77311-118-07LF is RoHS Compliant with Tin post finish, while the 77311-118-07 is RoHS non-compliant with Tin-Lead post finish. The LF variant also provides specified operating temperature range and current rating specifications.

Q: Can I use the 77311-118-07LF as a direct replacement for the 77311-118-07?

A: Yes, the 77311-118-07LF is a direct substitute. It maintains all critical electrical and mechanical parameters while offering improved compliance status for regulated applications.

Q: What does the "LF" designation indicate?

A: The "LF" suffix indicates Lead-Free composition, reflecting RoHS compliance requirements. This designation applies to the post finish material specification.

Q: Are there any assembly process differences between these parts?

A: Both parts use solder termination and are compatible with standard through-hole assembly processes. The post finish composition difference (Tin-Lead versus Tin) does not require process modifications.

Q: What is the moisture sensitivity level for both parts?

A: Both the 77311-118-07 and 77311-118-07LF carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
