Key Parameters

Substitute Part Grouping Explanation

The substitute part 17281-3PG-300 (Conxall/Switchcraft Micro-Con-X® series) qualifies as an equivalent based on the following matching parameters:

• Connector type: Receptacle with male pins
• Position count: 3 positions
• Mounting configuration: Panel mount, through-hole with bulkhead front-side nut
• Termination method: Solder
• Fastening mechanism: Bayonet lock
• Orientation: Keyed
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP67 rating
• Shielding: Unshielded design

The substitute part exceeds the original specification in current rating (7.5A vs. 5A) and includes additional voltage and temperature ratings, making it suitable for direct replacement in applications previously using the A-CR-03PMMP-LC-WP.

Parameter Comparison

Engineering Selection Recommendations

The 17281-3PG-300 is the recommended substitute for the obsolete A-CR-03PMMP-LC-WP. Both connectors share identical mechanical and electrical interface specifications across all critical parameters. The substitute part offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The substitute meets ROHS3 compliance requirements, whereas the original part status is not specified. Both parts maintain equivalent REACH and ECCN classifications. The increased current rating of the substitute (7.5A versus 5A) provides additional design margin without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 17281-3PG-300 be used as a direct replacement for the A-CR-03PMMP-LC-WP?
