Key Parameters

Substitute Part Grouping Explanation

Substitution of the 42-00003 is determined by equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 4
• Shell size: M8-4
• Fastening type: Threaded
• Current rating: 3A
• Voltage rating: 30V
• Ingress protection: IP67
• Operating temperature range: -30°C to 85°C
• Mounting type: Free Hanging (In-Line)
• Shell material and finish: Zinc die cast with nickel finish
• Contact finish: Gold
• Shielding: Unshielded
• Backshell material: Polyamide (PA6), Nylon 6, Glass Filled
• RoHS and REACH compliance status

Variable Parameter:

• Termination type: The primary distinction between the main part and its substitute is the termination method. The 42-00003 uses spring-type termination, while the 42-00007 substitute uses solder cup termination. Both termination types are functionally equivalent for establishing electrical connections within the specified electrical parameters.

The 42-00007 is an active product, providing continued availability and supply chain stability compared to the obsolete 42-00003.

Parameter Comparison

Engineering Selection Recommendations

The 42-00007 serves as the direct substitute for the obsolete 42-00003. Both components maintain identical electrical and mechanical specifications across all critical parameters including connector type, pin count, shell size, current and voltage ratings, ingress protection, and operating temperature range.

The primary distinction is termination methodology: the 42-00003 employs spring-type termination while the 42-00007 uses solder cup termination. Both termination approaches deliver equivalent electrical performance within the specified 3A current and 30V voltage parameters.

The 42-00007 holds active product status, ensuring ongoing manufacturer support, availability, and compliance maintenance. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The 42-00007 is available in bulk packaging, supporting production-scale deployments.

Selection of the 42-00007 eliminates obsolescence risk while preserving full functional compatibility with existing system designs utilizing the 42-00003.

Frequently Asked Questions (FAQ)

Q: Can the 42-00007 directly replace the 42-00003 in existing applications?

A: Yes. The 42-00007 maintains identical electrical ratings (3A, 30V), mechanical dimensions (M8-4 shell size), connector configuration (4-position receptacle with male pins), and environmental specifications (IP67, -30°C to 85°C operating range). The termination method differs (solder cup versus spring type), but both deliver equivalent electrical performance.

Q: What is the primary reason for substituting the 42-00003?

A: The 42-00003 is classified as obsolete. The 42-00007 is an active product, providing assured supply chain continuity, manufacturer support, and compliance maintenance.

Q: Are there compatibility concerns with the different termination types?

A: No. Spring-type and solder cup terminations are functionally equivalent connection methods. Selection between them depends on assembly process requirements and cable attachment methodology, not electrical performance.

Q: Do both parts meet current regulatory standards?

A: Yes. Both the 42-00003 and 42-00007 are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory requirements.

Q: What packaging options are available for the 42-00007?

A: The 42-00007 is supplied in bulk packaging, suitable for production-scale component procurement.

Q: Are the mechanical dimensions identical between the two parts?

A: Yes. Both parts feature M8-4 shell size, threaded fastening, free-hanging in-line mounting, and identical cable opening specifications (0.157" to 0.217" / 4.00mm to 5.50mm).

Q: Do both parts provide the same ingress protection rating?

A: Yes. Both the 42-00003 and 42-00007 provide IP67 ingress protection, delivering dust-tight and waterproof performance.
