Amphenol CONEC 42-00004 Circular Connector Plug - Equivalent & Substitute Parts

Part Overview

The Amphenol CONEC 42-00004 is a 4-position circular connector plug featuring female sockets with spring-type termination. This connector is designed for free-hanging, in-line applications requiring IP67-rated dust and moisture ingress protection. The product carries an Obsolete status, making identification of equivalent substitute components essential for system continuity and ongoing maintenance applications. The 42-00008 represents the direct active-status alternative within the same connector series.

Key Parameters

Substitute Part Grouping Explanation

The 42-00008 qualifies as a functional substitute for the 42-00004 based on the following critical electrical and mechanical parameters:

Matched Parameters:

• Manufacturer: Amphenol CONEC (same manufacturer)
• Connector Type: Plug, Female Sockets (identical)
• Number of Positions: 4 (identical)
• Shell Size - Insert: M8-4 (identical)
• Current Rating: 3A (identical)
• Voltage Rating: 30V (identical)
• Operating Temperature Range: -30°C ~ 85°C (identical)
• Ingress Protection: IP67 - Dust Tight, Waterproof (identical)
• Fastening Type: Threaded (identical)
• Mounting Type: Free Hanging (In-Line) (identical)

Primary Difference: The termination method differs between the parts: the 42-00004 uses spring-type termination, while the 42-00008 uses solder-cup termination. This substitution is valid only when the application can accommodate solder-cup connections in place of spring-type connections. Both termination types provide equivalent electrical and mechanical performance within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol CONEC 42-00008 serves as the functional equivalent for the obsolete 42-00004 across all critical electrical and mechanical parameters. Both connectors maintain identical performance specifications for current handling (3A), voltage rating (30V), operating temperature range (-30°C to 85°C), and IP67 ingress protection classification.

The primary consideration for selection between these parts is termination method. The 42-00004 employs spring-type termination for quick-connect applications, while the 42-00008 uses solder-cup termination for permanent soldered connections. Both approaches provide equivalent electrical reliability within the specified parameter envelope.

The 42-00008 carries Active product status with RoHS3 compliance and Unlimited moisture sensitivity level rating (MSL 1), providing assurance of continued manufacturing availability and regulatory alignment. The 42-00004, designated as Obsolete, should be replaced with the 42-00008 for new designs and maintenance applications where termination method compatibility can be accommodated.

Frequently Asked Questions (FAQ)

Q: Can the 42-00008 directly replace the 42-00004 in existing assemblies?

A: Electrical and mechanical compatibility is confirmed across all critical parameters (current, voltage, temperature range, ingress protection, shell size, and connector type). However, replacement feasibility depends on the application's termination requirements. The 42-00004 uses spring-type termination while the 42-00008 uses solder-cup termination. Both methods provide equivalent performance but require different cable/assembly preparation techniques.

Q: What are the key parameters that define substitutability for these connectors?

A: Substitution eligibility is determined by the following parameters: connector type (Plug, Female Sockets), number of positions (4), shell size (M8-4), current rating (3A), voltage rating (30V), operating temperature range (-30°C to 85°C), IP67 ingress protection classification, mounting type (Free Hanging, In-Line), and fastening type (Threaded). All these parameters match between the two connectors.

Q: Are there compliance or regulatory differences between the 42-00004 and 42-00008?

A: Both connectors maintain identical compliance certifications: RoHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), and UL94 flammability rating. Both parts carry the same ECCN (EAR99) and HTSUS classifications. Compliance status does not affect substitution eligibility.

Q: What inventory and product status considerations apply to this substitution?

A: The 42-00004 is designated Obsolete with 678 pieces in current inventory. The 42-00008 is in Active production status with 1,156 pieces available. For ongoing applications, the 42-00008 provides assurance of continued component availability and manufacturing support.

Q: Does packaging format affect the substitution decision?

A: The 42-00004 packaging is not specified in the documentation (marked as "-"). The 42-00008 is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility for the connector function itself but should be considered for procurement and inventory management workflows.
