Both connectors share identical core specifications: 3-position receptacle configuration, bayonet lock fastening, gold-plated contacts, and IP67 ingress protection. The substitute part offers superior electrical ratings (7.5A versus 5A) and defined operating temperature range (-40°C ~ 85°C), providing enhanced performance margins for existing applications.

The substitute part maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Both connectors are classified under HTSUS code 8536.69.4020 and carry EAR99 ECCN designation with REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 17281-3PG-300 directly replace the A-CR-03PMMS-LC-WP in existing designs?

A: Yes. Both connectors share identical mechanical and electrical interface specifications: 3-position bayonet lock receptacle with gold-plated contacts and IP67 protection. The substitute part accommodates the same panel mount configuration and solder termination method.

Q: What are the key differences between these two connectors?

A: The primary differences are product status and electrical specifications. The 17281-3PG-300 is an active product with defined voltage (600VAC/DC) and temperature ratings (-40°C ~ 85°C), compared to the obsolete A-CR-03PMMS-LC-WP. The substitute also provides higher current capacity (7.5A versus 5A) and ROHS3 compliance.

Q: Are there packaging considerations when switching to the substitute part?

A: The substitute part is supplied in bulk packaging, whereas the original part packaging is not specified. Verify bulk packaging compatibility with your assembly and inventory management processes.

Q: Does the substitute part maintain the same ingress protection rating?

A: Yes. Both connectors maintain IP67 ingress protection, ensuring equivalent dust-tight and waterproof performance in sealed applications.

Q: What compliance certifications apply to the substitute part?

A: The 17281-3PG-300 is ROHS3 compliant and carries REACH unaffected status. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications.
