Amphenol ICC 47736-000LF Socket Contact Rectangular Connector

Part Overview

The Amphenol ICC 47736-000LF is an active rectangular connector socket contact designed for 18-20 AWG wire applications with tin contact finish. This component is part of the Maxi-PV™ and Basics+ series and is RoHS compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical specifications (wire gauge, contact termination method, contact finish) and mechanical compatibility within the rectangular connector category.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Wire Gauge: 18-20 AWG (primary electrical compatibility criterion)
Contact Termination: Crimp (mechanical attachment method)
Contact Finish: Tin (corrosion resistance and solderability)
Pin or Socket: Socket (form factor requirement)
RoHS and MSL Compliance: Regulatory and environmental compatibility

Substitute parts are grouped into two categories:

Category A: Direct Rectangular Connector Substitutes — Parts maintaining socket contact configuration, 18-20 AWG wire gauge, crimp termination, and tin finish within the rectangular connector category.

Category B: Cross-Category Substitutes — Parts with matching electrical specifications (18-20 AWG, crimp termination, tin finish) but different mechanical form factors (blade-type connectors) or contact material variations.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

Parts 1393366-1 (TE Connectivity) and 0334680003, 0334680004 (Molex) maintain identical socket contact configuration, 18-20 AWG wire gauge, crimp termination, and tin finish. All are active products with ROHS3 compliance and MSL 1 rating, ensuring direct functional equivalence.

Secondary Substitutes (Electrical Equivalence with Form Factor Variation):

Part 0008520112 (Molex KK Trifurcon 6838) provides electrical compatibility through matching wire gauge, crimp termination, and tin finish but uses non-gendered contact configuration rather than socket-specific design.

Contact Finish Alternatives:

Parts 0008580187 (Molex) and 1326028-1 (TE Connectivity) maintain 18-20 AWG wire gauge and crimp termination but feature gold contact finish instead of tin. Gold finish provides enhanced corrosion resistance and is suitable for applications requiring superior contact reliability.

Cross-Category Substitute:

Part 0945180101 (Molex High Normal Force blade connector) matches electrical specifications (18-20 AWG, crimp, tin finish) but represents a different mechanical form factor (female blade socket versus rectangular socket). This substitute is applicable only when connector housing compatibility permits blade-type integration.

All recommended substitutes maintain active product status and regulatory compliance (ROHS3, MSL 1, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can 0334680003 directly replace 47736-000LF in existing assemblies?

A: Yes. Both parts are socket contacts with 18-20 AWG wire gauge, crimp termination, and tin finish. Compatibility depends on connector housing and mating interface specifications, which are not provided in this reference.

Q: What is the difference between tin and gold contact finishes?

A: Tin finish (100.0µin / 2.54µm) provides standard corrosion resistance and solderability. Gold finish (3.00µin to 30.0µin) offers enhanced contact reliability and is preferred in high-reliability or high-cycle applications. Both finishes are RoHS compliant.

Q: Are Molex 0008520112 and Amphenol 47736-000LF interchangeable?

A: Both parts meet 18-20 AWG, crimp termination, and tin finish specifications. However, 0008520112 uses non-gendered contact configuration while 47736-000LF is socket-specific. Interchangeability depends on connector housing design and mating requirements.

Q: Why is 0945180101 listed as a substitute if it is a blade connector?

A: Part 0945180101 matches critical electrical parameters (18-20 AWG wire gauge, crimp termination, tin finish) but uses a different mechanical form factor (female blade socket). It is a substitute only for applications where blade-type connector housing is compatible with the assembly design.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 indicates unlimited shelf life and no moisture sensitivity restrictions. These parts do not require special storage conditions or baking procedures prior to assembly.

Q: Are all listed substitutes RoHS compliant?

A: Yes. The main part (47736-000LF) is RoHS Compliant. All substitute parts are ROHS3 Compliant, meeting current RoHS Directive requirements.
