Replacing discontinued waterproof circular connectors: your guide to compatible in-stock alternatives

Sourcing waterproof circular connectors can be a challenge, especially when legacy parts are discontinued or phased out. For operations managers and procurement teams, finding reliable, compatible alternatives quickly is essential to avoid downtime and keep systems running smoothly. This guide outlines what to look for in a replacement and highlights trusted brands offering IP-rated circular connectors that meet industrial demands.

What to look for in a replacement waterproof circular connector

When replacing a discontinued connector, compatibility and durability are key. Consider the following:

• IP Rating: IP67 and IP68 are common for waterproof connectors. IP67 protects against temporary immersion, while IP68 handles prolonged submersion.
• Pin Configuration & Shell Size: Match the number of contacts and physical dimensions to avoid redesigns.
• Mounting Style: Panel-mount, cable-mount, and PCB-mount options should align with your existing setup.
• Electrical Ratings: Voltage and current ratings must meet system requirements.
• Material & Sealing: Look for corrosion-resistant materials and integrated sealing features like O-rings or gaskets.

These factors ensure the replacement connector performs reliably in harsh environments, from outdoor installations to industrial machinery.
