HARTING 21038822425 Equivalent & Substitute Parts

Part Overview

The HARTING 21038822425 is a 4-position circular connector receptacle housing in the Han® M12 series, designed for free hanging (in-line) and panel mount applications. This component features a shielded design with IP65/IP67 ingress protection, operating across -40°C to 85°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this connector type is specified.

Substitute Part Grouping Explanation

The HARTING 21038812425 qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: HARTING (same manufacturer ensures design compatibility)
• Category: Circular Connectors
• Number of Positions: 4
• Shell Size - Insert: M12-4
• Mounting Type: Free Hanging (In-Line); Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Threaded
• Orientation: D
• Housing Color: Silver
• Ingress Protection: IP65/IP67
• Shielding: Shielded
• Operating Temperature: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Contact Type: Crimp
• Type: For Female Sockets

Key Difference: The substitute part is a plug housing (connector type) rather than a receptacle housing. This represents a mating pair relationship within the Han® M12 series ecosystem, where the plug and receptacle housings are designed to interface with each other. The substitute maintains all electrical and mechanical interface specifications required for M12-4 connectivity.

Parameter Comparison

Engineering Selection Recommendations

The HARTING 21038812425 is the designated substitute for the obsolete 21038822425. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across applications. The substitute part carries active product status, providing supply chain continuity and ongoing manufacturer support.

The primary distinction—plug housing versus receptacle housing—reflects the complementary nature of these components within the Han® M12 connector system. Selection between these parts depends on the specific application requirement: receptacle housings for fixed panel-mount installations receiving mating plugs, or plug housings for cable-mounted or removable connector applications.

Both parts share identical electrical and mechanical interface specifications (M12-4 shell size, 4-position configuration, threaded fastening, D-orientation), ensuring seamless integration within systems designed for Han® M12 connectivity.

Frequently Asked Questions (FAQ)

Q: Why is the substitute part listed as a plug housing when the main part is a receptacle housing?

A: The substitute represents the mating connector type within the Han® M12 series. Both components are designed to interface with each other and share all critical electrical and mechanical parameters (shell size M12-4, 4-position, orientation D, IP65/IP67 protection, operating temperature range). The connector type difference reflects the complementary roles these parts play in complete connector assemblies.

Q: Are the operating temperature ranges identical?

A: Yes. Both the main part (21038822425) and substitute (21038812425) operate across -40°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: What is the significance of the "Slim Design" designation in the substitute part series?

A: The Han® M12 Slim Design variant maintains all specified interface parameters and performance characteristics of the standard Han® M12 series. The design optimization does not affect the electrical or mechanical compatibility criteria used for substitution determination.

Q: Are both parts RoHS compliant?

A: Yes. Both the main part and substitute are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the difference in product status, and why does it matter?

A: The main part (21038822425) is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute (21038812425) maintains active product status, ensuring ongoing availability, manufacturer support, and supply chain reliability for new designs and system maintenance.

Q: Do both parts require contacts to be purchased separately?

A: Yes. Both the main part and substitute are supplied without contacts included. Contacts must be sourced separately and crimped according to HARTING specifications for the M12-4 connector system.
