Amphenol CONEC 42-00002 Circular Connector Plug - Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 42-00002 is a 3-position circular connector plug with female sockets and spring-type termination. This connector is designed for free-hanging, in-line applications requiring IP67 ingress protection in dust and moisture environments. The part is classified as obsolete, making identification of equivalent substitute components essential for system maintenance, repair, and redesign applications where continued supply from original inventory is limited.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 42-00002 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug with female sockets
• Number of positions: 3
• Shell size and insert designation: M8-3
• Fastening type: Threaded
• Orientation: A
• Current rating: 3A
• Voltage rating: 60V
• Ingress protection: IP67
• Operating temperature range: -30°C to 85°C
• Series designation: 42

Variable Parameter (Allows Substitution):

• Termination type: The 42-00002 uses spring-type termination. Substitute parts may employ alternative termination methods (such as solder cup) provided all other parameters remain identical.

The 42-00006 qualifies as a direct substitute because it maintains equivalence across all mandatory parameters while differing only in termination technology, which is an acceptable variation for connector substitution within the same series and shell size.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The 42-00002 is classified as obsolete, while the 42-00006 maintains active product status. For applications requiring long-term component availability and manufacturer support, the 42-00006 is the appropriate selection.

Compliance and Certification Equivalence

Both parts maintain identical compliance certifications:

• ROHS3 Compliant
• REACH Unaffected
• EAR99 ECCN classification
• HTSUS code 8536.69.4020

These certifications are maintained across the substitution, ensuring regulatory equivalence for applications subject to environmental and trade compliance requirements.

Termination Technology Difference

The 42-00002 employs spring-type termination, while the 42-00006 uses solder cup termination. This difference affects cable connection methodology but does not alter electrical performance, mechanical fit, or environmental protection characteristics. Selection between these termination types depends on the specific cable assembly and connection process requirements of the application.

Electrical and Environmental Performance

Both connectors deliver identical electrical performance (3A at 60V) and environmental protection (IP67). Operating temperature ranges are equivalent (-30°C to 85°C), ensuring functional equivalence across specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the 42-00006 directly replace the 42-00002 in existing applications?

A: The 42-00006 is electrically and mechanically equivalent to the 42-00002 across all critical parameters. However, the difference in termination type (solder cup versus spring type) requires assessment of the cable assembly connection method. If the application uses spring-type cable terminations, the connection interface differs and may require cable assembly modification.

Q: Why is the 42-00002 classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The 42-00006 represents the active equivalent within the same series, offering identical performance with updated termination technology.

Q: Are there compliance differences between the two parts?

A: No. Both parts maintain identical RoHS3, REACH, ECCN, and HTSUS classifications. Regulatory compliance is equivalent for both components.

Q: What is the primary difference between spring-type and solder cup termination?

A: Spring-type termination uses mechanical spring contacts for cable connection, while solder cup termination requires soldering the cable conductors into the connector cup. The choice depends on the cable assembly process and connection methodology specified for the application.

Q: Is the 42-00006 available in the same packaging as the 42-00002?

A: The 42-00002 is supplied in standard packaging, while the 42-00006 is supplied in bulk packaging. Packaging format may affect procurement and inventory management but does not alter component functionality.

Q: Can both parts be used interchangeably in new designs?

A: The 42-00006 is recommended for new designs due to its active product status and assured long-term availability. The 42-00002, being obsolete, should be reserved for legacy system maintenance where existing cable assemblies with spring-type terminations are already in use.

Q: What is the cable opening specification for both connectors?

A: Both the 42-00002 and 42-00006 accommodate cable diameters of 0.157" to 0.217" (4.00mm to 5.50mm), ensuring equivalent cable compatibility.
