HARTING 21038222425 Equivalent & Substitute Parts

Part Overview

The HARTING 21038222425 is a 4-position circular connector receptacle housing from 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the 21038222425 is constrained by critical mechanical and electrical parameters that define functional compatibility within the Han® M12 connector ecosystem. The primary limiting factors are:

Position Count & Shell Size: The main part specifies 4 positions with M12-4 shell size. Substitute parts must accommodate the same contact count and mating interface to ensure mechanical fit within existing panel cutouts and backshell assemblies.

Connector Type Polarity: The main part is a receptacle housing (female socket type). Substitutes must maintain this polarity to mate with existing plug connectors in the field.

Mounting Configuration: Both free hanging (in-line) and panel mount capability are required parameters. Substitutes must support identical mounting flexibility.

Environmental Sealing: IP65/IP67 rating is mandatory for the intended application environment. Substitutes must maintain this ingress protection level.

Temperature Range: Operating range of -40°C to 85°C establishes the thermal envelope. Substitutes must support this full range.

Shielding & Compliance: Shielded construction and ROHS3 compliance are non-negotiable specifications.

The identified substitute (21038212525) does not meet the position count requirement (5 positions vs. 4 positions) and uses a different shell size (M12-5 vs. M12-4), making it mechanically incompatible as a direct substitute. This part represents a different connector configuration within the same series and cannot be used as a replacement without redesign of the mating interface.

Parameter Comparison

Engineering Selection Recommendations

The 21038222425 is classified as obsolete. While the listed substitute (21038212525) shares the Han® M12 series platform and maintains equivalent environmental ratings and compliance certifications, it is not a direct mechanical substitute due to fundamental differences in connector type (plug vs. receptacle), position count (5 vs. 4), and shell size (M12-5 vs. M12-4).

For applications currently using the 21038222425, component selection must prioritize:

Existing Inventory: 902 units of the main part remain in stock as new original components, providing immediate availability for current production or maintenance requirements.

Functional Equivalence: Direct substitution requires a 4-position receptacle housing with M12-4 shell size, threaded fastening, and identical mounting flexibility. The listed part does not meet these criteria.

Compliance Continuity: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment regardless of substitution path.

Active vs. Obsolete Status: The substitute part carries active product status, indicating ongoing manufacturer support and availability. However, this advantage is negated by mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the 21038212525 be used in place of the 21038222425?

A: No. The 21038212525 is a 5-position plug housing with M12-5 shell size, while the 21038222425 is a 4-position receptacle housing with M12-4 shell size. These are mechanically incompatible and cannot mate with the same backshell or panel cutout configurations.

Q: Why is the main part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. However, existing inventory (902 units) remains available as new original stock for current applications.

Q: Are there environmental or compliance differences between these parts?

A: Both parts maintain identical ingress protection (IP65/IP67), operating temperature range (-40°C to 85°C), and regulatory compliance (ROHS3, REACH unaffected). Environmental performance is equivalent.

Q: What is the difference between threaded and push-twist fastening?

A: The main part uses threaded fastening (screw-on connection), while the substitute uses push-twist (bayonet-style connection). These are distinct mechanical interfaces and are not interchangeable.

Q: If I need a substitute for the 21038222425, what parameters must match?

A: Any substitute must be a 4-position receptacle housing with M12-4 shell size, support both free hanging and panel mount configurations, maintain IP65/IP67 sealing, and operate across -40°C to 85°C. Fastening type (threaded) and shielding must also be preserved.

Q: Is the substitute part more current than the main part?

A: Yes, the 21038212525 carries active product status, indicating ongoing manufacturer support. However, active status does not establish functional equivalence for this application.
