Key Parameters

Substitute Part Grouping Explanation

Substitution of the A-CR-04PMMP-LC-WP is based on strict equivalence across the following critical parameters:

• Connector type and pin configuration (Receptacle, Male Pins, 4-position)
• Mechanical interface (Panel Mount, Through Hole, Bulkhead mounting, Bayonet Lock fastening)
• Electrical termination method (Solder)
• Contact material and finish (Copper Alloy with Gold plating)
• Keyed orientation for polarization
• Unshielded configuration

The substitute part EN3P4MPX from Switchcraft Inc. meets all these core requirements. While the substitute offers enhanced specifications in certain areas (higher current rating, extended ingress protection, operating temperature range, and active product status), these improvements do not preclude functional equivalence. The substitute maintains mechanical and electrical compatibility with the original part's interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The EN3P4MPX circular connector from Switchcraft Inc. serves as the primary equivalent for the obsolete A-CR-04PMMP-LC-WP. Selection of this substitute is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance aligns with current regulatory requirements
• Mechanical and electrical interface compatibility with the original part
• Enhanced specifications (higher current rating, extended ingress protection, defined operating temperature range, and voltage rating) provide performance margin without introducing incompatibility
• Both parts maintain REACH Unaffected status and EAR99 ECCN classification

Frequently Asked Questions (FAQ)

Q: Can EN3P4MPX be used as a direct replacement for A-CR-04PMMP-LC-WP?

A: Yes. Both connectors share identical mechanical interfaces (4-position, panel mount, through-hole, bulkhead mounting, bayonet lock), electrical termination (solder), contact material and finish (copper alloy with gold plating), and keyed orientation. The substitute maintains full compatibility with existing mating connectors and PCB layouts.

Q: What are the key differences between these parts?

A: The EN3P4MPX offers enhanced specifications including higher current rating (7.5A vs. 5A), extended ingress protection (IP66/IP68 vs. IP67), defined operating temperature range (-40°C to 65°C), specified voltage rating (250VAC/DC), and ROHS3 compliance. These improvements do not affect mechanical or electrical compatibility.

Q: Why is the original part obsolete?

A: The A-CR-04PMMP-LC-WP is listed as obsolete by the manufacturer. The EN3P4MPX remains in active production, ensuring long-term component availability and support.

Q: Are there packaging differences?

A: The original part packaging is not specified. The EN3P4MPX is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts meet the same compliance standards?

A: Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The EN3P4MPX additionally carries ROHS3 compliance certification, meeting current regulatory requirements.
