Amphenol ICC 71918-140 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71918-140 is a rectangular connector header for through-hole mounting with 40 positions at 2.54mm pitch. This component is classified as obsolete, with limited inventory of 750 pieces. Due to its obsolete status and the availability of active product alternatives from both Amphenol ICC and TE Connectivity, equivalent substitute parts are necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Matching Criteria:

Connector type (Header)
Contact type (Male Pin)
Number of positions (40)
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)

Secondary Compatibility Factors:

Contact finish - mating (Gold or Gold-Palladium acceptable)
Material flammability rating (UL94 V-0)
Moisture sensitivity level (1 / Unlimited)

Parts are grouped into two categories:

Category A - Direct Amphenol ICC Substitutes: Parts maintaining the Quickie™ series designation with identical mechanical and electrical interfaces. The 71918-140LF is the active production equivalent with RoHS compliance.

Category B - TE Connectivity AMP-Latch Series: Parts from TE Connectivity's AMP-Latch series that meet all critical dimensional and functional parameters. These parts feature extended operating temperature range (-65°C to 105°C) and specified current/voltage ratings (1A per contact, 250VAC).

Category C - Limited Compatibility: The 71922-034LF differs in position count (34 vs. 40) and mounting orientation (right angle vs. vertical), making it unsuitable for direct substitution.

Engineering Selection Recommendations

Primary Recommendation - Amphenol ICC 71918-140LF

The 71918-140LF is the direct active production equivalent from Amphenol ICC. It maintains identical mechanical dimensions, electrical characteristics, and series designation (Quickie™) as the obsolete 71918-140. The primary distinction is RoHS compliance status. This part is suitable for new designs and ongoing production requiring Amphenol ICC components.

Secondary Recommendations - TE Connectivity AMP-Latch Series

The TE Connectivity parts (102321-9, 2-5499206-9, 499206-9, 499922-9, 5102321-9, 5499206-9, 5499922-9, 5499923-9) meet all critical dimensional and functional parameters. These parts offer:

Extended operating temperature range: -65°C to 105°C
Specified electrical ratings: 1A per contact, 250VAC
Multiple RoHS compliance options (ROHS3 Compliant, Not applicable, Non-compliant)
High inventory availability, particularly 5499922-9 (341,976 pieces) and 5499206-9 (62,598 pieces)

Selection among TE Connectivity variants depends on packaging requirements (Tray or Bulk) and RoHS compliance mandates for the end application.

Not Recommended for Direct Substitution

The 71922-034LF is not suitable as a direct substitute due to reduced position count (34 vs. 40) and right-angle mounting orientation, which alter the mechanical interface and board layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the 71918-140LF be used as a direct replacement for the 71918-140?

A: Yes. The 71918-140LF is the active production equivalent with identical mechanical and electrical specifications. The primary difference is RoHS compliance status. Both parts maintain the same 40-position, 2.54mm pitch configuration and Quickie™ series designation.

Q: What are the key differences between Amphenol ICC and TE Connectivity substitutes?

A: Amphenol ICC parts (71918-140LF) maintain the original Quickie™ series design. TE Connectivity parts use the AMP-Latch series platform with extended operating temperature range (-65°C to 105°C) and specified current/voltage ratings. Both meet the core dimensional and functional requirements for 40-position, 2.54mm pitch through-hole headers.

Q: Are TE Connectivity parts mechanically compatible with the original 71918-140?

A: Yes. All TE Connectivity AMP-Latch parts listed maintain identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), position count (40), row count (2), shrouding (4-wall), and termination method (solder). Mechanical compatibility is confirmed across all critical interface parameters.

Q: What packaging options are available?

A: Amphenol ICC 71918-140LF is supplied in Tube packaging. TE Connectivity parts are available in Tray packaging (102321-9, 2-5499206-9, 499206-9, 5102321-9, 5499206-9) or Bulk packaging (499922-9, 5499922-9, 5499923-9). Packaging selection depends on assembly process requirements and inventory management practices.

Q: Which substitute part has the highest inventory availability?

A: TE Connectivity 5499922-9 has the highest inventory with 341,976 pieces in stock. This part is ROHS3 compliant and supplied in Bulk packaging.

Q: Does the 71922-034LF work as a substitute?

A: No. The 71922-034LF has 34 positions instead of 40 and uses right-angle mounting instead of vertical. These differences alter the mechanical interface and are not compatible with designs specified for the 40-position vertical configuration.

Q: What RoHS compliance options are available?

A: Amphenol ICC 71918-140LF is RoHS Compliant. TE Connectivity options include ROHS3 Compliant (2-5499206-9, 5102321-9, 5499922-9, 5499923-9), RoHS Compliant (5499206-9), and Not applicable (102321-9, 499206-9, 499922-9). Selection depends on regulatory requirements for the end application.

Q: Are contact finish specifications identical across all substitutes?

A: The original 71918-140 and 71918-140LF specify Gold, GXT™ mating finish. TE Connectivity parts specify Gold or Gold-Palladium mating finish. Both finishes provide equivalent electrical performance and corrosion resistance for standard applications.
