Amphenol ICC 71918-020 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71918-020 is an active-status vertical rectangular connector header designed for through-hole mounting applications. This 20-position, 2-row shrouded header with 0.100" (2.54mm) pitch serves board-to-cable/wire interconnection requirements. The part features gold-plated mating contacts, phosphor bronze material, and UL94 V-0 flammability rating. Substitute parts are identified to address RoHS compliance requirements, inventory availability, or alternative manufacturer sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 71918-020 is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (20), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting type (through hole), shrouding configuration (shrouded - 4 wall), termination method (solder), and fastening type (push-pull). All identified substitutes maintain these core electrical and mechanical specifications.

The 71918-020LF is a direct manufacturer equivalent from Amphenol ICC with identical core specifications and RoHS-compliant status. The 102153-4 from TE Connectivity AMP Connectors represents a cross-manufacturer substitute that meets all critical dimensional and functional parameters while offering alternative sourcing and compliance profiles.

Engineering Selection Recommendations

The 71918-020LF is the primary substitute for the 71918-020, offering identical electrical and mechanical specifications with the addition of RoHS compliance. Both parts maintain active product status and are sourced from the same manufacturer. Selection of the 71918-020LF is appropriate when RoHS-compliant components are required for the application.

The 102153-4 from TE Connectivity AMP Connectors provides cross-manufacturer substitution with equivalent core functionality. This part maintains all critical mating and mounting parameters while offering alternative sourcing. The 102153-4 includes operating temperature specification (-55°C ~ 105°C) and current rating (1A per contact) not provided for the primary part. Dimensional variations exist in contact length and insulation height; these differences do not preclude functional compatibility in standard through-hole applications but should be evaluated against specific PCB layout and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the 71918-020LF be used as a direct replacement for the 71918-020?

A: Yes. The 71918-020LF maintains identical electrical and mechanical specifications including connector type, contact configuration, pitch, mounting method, and shrouding. The primary difference is RoHS compliance status.

Q: What are the key differences between the 71918-020 and the 102153-4?

A: Both parts share identical mating pitch (0.100"/2.54mm), row configuration (2 rows, 20 positions), mounting type (through hole), and shrouding (4-wall). Differences include manufacturer (Amphenol ICC versus TE Connectivity), series designation (Quickie™ versus AMP-Latch), contact length specifications, and insulation height. The 102153-4 provides operating temperature and current rating specifications.

Q: Are there packaging differences between these substitutes?

A: Yes. The 71918-020 and 71918-020LF are supplied in tube packaging, while the 102153-4 is supplied in tray packaging. Packaging selection may affect inventory handling and component placement processes.

Q: Which substitute should be selected for RoHS-compliant applications?

A: The 71918-020LF is RoHS compliant and maintains all specifications of the original 71918-020. This part is the appropriate selection for applications requiring RoHS compliance.

Q: Can the 102153-4 be used in applications originally designed for the 71918-020?

A: The 102153-4 maintains all critical mating and mounting parameters required for through-hole board-to-cable/wire interconnection. Dimensional variations in contact length and insulation height exist; compatibility should be confirmed against specific mating connector and PCB layout requirements for the application.
