Amphenol ICC 71918-014 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71918-014 is a shrouded rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 14-position, 2-row connector with 0.100" (2.54mm) pitch operates in the Quickie™ series and features gold-plated mating contacts with phosphor bronze material. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71918-014 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (14 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact shape (Square)
• Flammability rating (UL94 V-0)

The three substitute parts listed—71918-014LF, 102154-2, and 3314-6002—meet these core electrical and mechanical requirements. Variations in contact length, insulation height, contact finish thickness, and product status are secondary considerations that do not prevent functional substitution in applications designed for the 71918-014.

Parameter Comparison

Engineering Selection Recommendations

71918-014LF is the primary substitute for the obsolete 71918-014. Both parts are from Amphenol ICC's Quickie™ series and share identical mating contact length, post length, and insulation height. The 71918-014LF is currently active in production and carries RoHS Compliant status, making it suitable for new designs and ongoing procurement. The only material difference is the addition of tin finish on the post contacts in the LF variant.

102154-2 from TE Connectivity AMP Connectors is an active alternative that meets all core substitution criteria. This part operates across a specified temperature range of -65°C to 105°C and carries a 1A per contact current rating. The insulation height is notably lower (0.549" vs. 0.685"), and the contact lengths are slightly longer. This part is suitable for applications where the dimensional and thermal specifications align with design requirements.

3314-6002 from 3M is an obsolete part from the 3000 series. While it meets all fundamental electrical and mechanical substitution parameters, its obsolete status and RoHS non-compliant classification limit its use to legacy system support or applications where RoHS compliance is not required. The contact finish thickness on the post is significantly higher (200.0µin vs. 30.0µin), and the operating temperature range extends to -55°C.

Frequently Asked Questions (FAQ)

Q: Can 71918-014LF be used as a direct replacement for 71918-014?

A: Yes. Both parts are Amphenol ICC Quickie™ series headers with identical pitch, position count, row configuration, shrouding, and contact dimensions. The LF variant adds RoHS compliance and tin post finish, making it functionally equivalent for board-to-cable/wire applications.

Q: What are the key dimensional differences between these substitutes?

A: The 71918-014 and 71918-014LF share identical contact and insulation dimensions. The 102154-2 has a lower insulation height (0.549" vs. 0.685") and longer mating contacts (0.240" vs. 0.228"). The 3314-6002 has similar insulation height to the main part but longer mating contacts. These differences may affect mechanical fit in constrained board layouts.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is a regulatory requirement for products sold in the European Union and certain other markets. The 71918-014LF is RoHS Compliant, while the main part and 3314-6002 are non-compliant. The 102154-2 carries "Not applicable" status. Select based on your market and regulatory requirements.

Q: Are there temperature or current rating differences I should consider?

A: The 102154-2 and 3314-6002 specify operating temperature ranges (-65°C to 105°C and -55°C to 105°C respectively) and current ratings (1A per contact or 1A). The main part and 71918-014LF do not specify these parameters. If your application requires defined thermal or current specifications, the TE Connectivity or 3M alternatives provide explicit ratings.

Q: What is the difference between the contact finishes?

A: All parts feature gold mating contact finish at 30.0µin thickness. The main part does not specify post finish, while 71918-014LF adds tin post finish. The 102154-2 uses tin-lead post finish (100.0µin), and 3314-6002 uses tin-lead post finish (200.0µin). These variations do not affect mating compatibility but may influence soldering characteristics and long-term reliability in specific environments.

Q: Can I mix these parts in the same assembly?

A: All four parts are mechanically and electrically compatible for mating with standard 0.100" (2.54mm) pitch connectors. However, mixing parts with different insulation heights or contact lengths in the same assembly may create mechanical inconsistencies. Standardize on a single part number per design for optimal assembly and field serviceability.
