HC-D 25-SML-57/O2M25 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact HC-D 25-SML-57/O2M25 is a heavy duty base connector for box mount applications with side entry configuration, M25 thread size, and D25 connector size. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across -40°C to 125°C. The part is currently obsolete, making identification of equivalent substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC-D 25-SML-57/O2M25 is determined by the following critical parameters:

• Connector Type: Base - Box Mount
• Style: Side Entry
• Size: D25
• Thread Size: M25
• Lock Location: Locking Clip (1) on Base Bottom
• Series: HEAVYCON® D
• Housing Material: Aluminum, Die Cast
• Operating Temperature Range: -40°C ~ 125°C
• RoHS Compliance: Required

The substitute part 1424393 maintains all core mechanical and electrical compatibility parameters. The primary difference is enhanced ingress protection (IP66/IP67 versus IP65) and improved environmental resistance (salt water resistant), which represents a functional upgrade rather than a deviation from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact part number 1424393 is the direct substitute for the obsolete HC-D 25-SML-57/O2M25. Both components are RoHS compliant and maintain identical mechanical interfaces, connector sizing, and thermal operating ranges. The substitute part 1424393 is currently in active production status with 1058 units in stock, ensuring supply chain continuity.

The upgrade from IP65 to IP66/IP67 ingress protection and the addition of salt water resistance in part 1424393 provide enhanced environmental durability without compromising mechanical or electrical compatibility. This represents a specification improvement suitable for applications requiring extended environmental protection.

Frequently Asked Questions (FAQ)

Q: Can part 1424393 directly replace the obsolete HC-D 25-SML-57/O2M25?

A: Yes. Both parts share identical connector type, style, size, thread size, lock mechanism, housing material, and operating temperature range. The mechanical interface is fully compatible.

Q: What is the difference in ingress protection between these parts?
