Amphenol ICC 47437-000 Socket Contact Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 47437-000 is a socket contact for rectangular connectors, designed for 28-32 AWG wire gauges with gold plating and crimp termination. This component is classified as obsolete, making it necessary to identify equivalent or substitute parts for new designs and ongoing production requirements. The part belongs to the Mini-PV™ and Basics+ series and is non-compliant with RoHS standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 47437-000 is determined by the following critical parameters:

• Contact Type: Socket configuration
• Wire Gauge Compatibility: 28-32 AWG range
• Contact Finish: Gold plating
• Moisture Sensitivity: MSL 1 rating
• Electrical Classification: HTSUS 8536.90.4000

Two substitute parts are identified based on these parameters:

1. 47437-000LF (Direct Amphenol ICC substitute): Maintains identical electrical and mechanical specifications with updated RoHS compliance and active product status.

2. 86477-2 (TE Connectivity alternative): Provides equivalent socket contact functionality with gold finish and MSL 1 rating, though with different termination method (solder/PCB vs. crimp).

Parameter Comparison

Engineering Selection Recommendations

For RoHS-compliant applications: The 47437-000LF is the direct replacement for the obsolete 47437-000. It maintains identical electrical and mechanical specifications while achieving RoHS compliance and active product status. This part is the preferred choice for new designs and production transitions.

For alternative connector systems: The 86477-2 from TE Connectivity provides equivalent socket contact functionality with gold finish and MSL 1 rating. However, this part uses solder/PCB termination instead of crimp termination, requiring design modification to the connector interface. Selection of this alternative depends on system-level compatibility with the AMPMODU Mod I series and solder-based assembly processes.

For legacy system maintenance: If the original 47437-000 must be retained for existing assemblies, inventory of 706 pieces is currently available. However, transition to 47437-000LF is recommended for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can 47437-000LF be used as a direct replacement for 47437-000?

A: Yes. The 47437-000LF maintains identical wire gauge (28-32 AWG), contact finish (gold), contact termination (crimp), and MSL rating (1). The primary differences are active product status and RoHS compliance, making it suitable for direct substitution in new and existing designs.

Q: What is the key difference between 47437-000LF and 86477-2?

A: The 47437-000LF uses crimp termination for wire attachment, while the 86477-2 uses solder/PCB termination. This fundamental difference in assembly method requires design-level evaluation. The 47437-000LF is the preferred substitute if crimp termination is required. The 86477-2 is an alternative only if the system can accommodate PCB-mounted solder connections.

Q: Does the contact finish thickness difference between 47437-000LF (40.0µin) and 86477-2 (30.0µin) affect compatibility?

A: Both finishes meet MSL 1 requirements and provide gold plating for corrosion resistance. The 40.0µin thickness of the 47437-000LF matches the original specification exactly. The 30.0µin thickness of the 86477-2 is acceptable for equivalent electrical performance but represents a design change requiring evaluation.

Q: What packaging options are available for these parts?

A: The 47437-000LF is supplied in Bulk packaging. The 86477-2 is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly line requirements.

Q: Are there any compliance or certification differences between these parts?

A: The 47437-000 is RoHS non-compliant. The 47437-000LF is RoHS Compliant. The 86477-2 has RoHS status listed as Not applicable. For applications requiring RoHS compliance, the 47437-000LF is the appropriate selection.
