Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5111374-4 are identified based on strict alignment with core electrical and mechanical parameters. The substitution criteria are established through the following key parameters:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 20
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Latch Lock/Eject Hooks
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The Amphenol ICC (FCI) part number 71918-120LF satisfies all primary matching criteria and is classified as a direct substitute within the rectangular connectors category. Both connectors maintain identical mating pitch, row configuration, position count, and mounting methodology. The substitute part operates within compatible electrical and mechanical parameters suitable for equivalent board-to-cable/wire interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5111374-4 is supplied in tray packaging with 828 pieces in current inventory. The Amphenol ICC 71918-120LF is supplied in tube packaging with 1221 pieces in current inventory. Both parts are suitable for equivalent electrical and mechanical performance in board-to-cable/wire interconnection applications requiring 20-position, dual-row, 0.100" pitch through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Are the TE Connectivity 5111374-4 and Amphenol ICC 71918-120LF connectors mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), position count (20), row configuration (2), mounting type (through hole), shrouding (4 wall), and fastening mechanism (latch lock/eject hooks). The connectors are mechanically interchangeable in applications designed for standard 0.100" pitch dual-row headers.

Q: What are the differences in contact dimensions between these two parts?

A: The TE Connectivity 5111374-4 features a contact length - mating of 0.240" (6.10mm) and insulation height of 0.549" (13.94mm). The Amphenol ICC 71918-120LF features a contact length - mating of 0.228" (5.80mm) and insulation height of 0.685" (17.40mm). These dimensional variations may affect mating depth and connector stack height in specific applications.

Q: What packaging options are available for these connectors?

A: The TE Connectivity 5111374-4 is supplied in tray packaging. The Amphenol ICC 71918-120LF is supplied in tube packaging. Packaging selection depends on assembly process requirements and inventory management protocols.

Q: Do both connectors meet the same compliance standards?

A: Both connectors achieve UL94 V-0 material flammability rating and maintain unlimited moisture sensitivity level (MSL 1). The TE Connectivity part carries ROHS3 compliance, while the Amphenol ICC part carries RoHS compliance with REACH affected status. Application-specific compliance requirements determine which certification is appropriate.

Q: What is the difference in contact finish specifications?

A: The TE Connectivity 5111374-4 features gold or gold-palladium mating contact finish with flash thickness. The Amphenol ICC 71918-120LF features gold GXT™ mating contact finish with 30.0µin (0.76µm) thickness. Both parts use tin contact finish on the post. Contact finish selection affects corrosion resistance and electrical performance in specific environmental conditions.

Q: Are these connectors suitable for the same current and voltage ratings?

A: The TE Connectivity 5111374-4 is rated for 1A per contact at 250VAC. The Amphenol ICC 71918-120LF does not specify current and voltage ratings in the provided data. Applications requiring specific electrical performance ratings should reference the TE Connectivity part specifications.
