TE Connectivity 212437-4 Circular Connector Plug Housing: Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 212437-4 is a 6-position circular connector plug housing designed for male pins with free-hanging (in-line) mounting configuration. This component features a DIN 240-degree shell size, push-pull fastening, and shielded construction with tin-plated brass shell material. The part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing procurement and system integration requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TE Connectivity 212437-4 is based on the following critical parameters that determine functional and mechanical compatibility:

Direct Equivalent Criteria:

• Connector type (plug housing for male pins)
• Number of positions (6)
• Shell size specification (DIN 240 Degree)
• Mounting configuration (free-hanging, in-line)
• Fastening mechanism (push-pull)
• Orientation (keyed)
• Contact type (crimp)
• Shielding requirement (shielded)
• Operating temperature range (-55°C ~ 105°C)

Part 9-212437-1 qualifies as a direct equivalent substitute. This TE Connectivity AMP Connectors component maintains identical specifications across all critical parameters while offering active product status and RoHS3 compliance, distinguishing it from the obsolete 212437-4.

Part 1170000000 (Weidmüller SAI series) represents a similar component with functional overlap but operates under different design specifications. This insert-only component features a different shell size designation (M23-6), unshielded construction, and extended operating temperature range (-40°C ~ 125°C). This part requires a separate shell assembly and does not provide direct plug housing functionality equivalent to the 212437-4.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 9-212437-1

The 9-212437-1 is the recommended substitute for the obsolete 212437-4. This component provides complete functional equivalence across all critical parameters: identical connector type, position count, shell size, mounting configuration, fastening mechanism, and operating temperature range. The 9-212437-1 maintains active product status and achieves RoHS3 compliance, addressing regulatory requirements that the obsolete 212437-4 does not satisfy. Both components are manufactured by TE Connectivity AMP Connectors, ensuring design continuity and compatibility with existing connector ecosystems.

Alternative Component: Weidmüller 1170000000

The Weidmüller 1170000000 is classified as a similar component rather than a direct equivalent. This insert-only component operates under different mechanical specifications: M23-6 shell size designation versus DIN 240 Degree, unshielded versus shielded construction, and extended operating temperature range (-40°C ~ 125°C). The 1170000000 requires separate shell procurement and assembly, introducing additional design and procurement complexity. This component is suitable only for applications where the specific M23-6 form factor and unshielded configuration are acceptable design modifications.

Frequently Asked Questions (FAQ)

Q: Can the 9-212437-1 be used as a direct replacement for the 212437-4 in existing assemblies?

A: Yes. The 9-212437-1 maintains identical specifications across all critical functional and mechanical parameters: 6-position DIN 240-degree plug housing, male pin configuration, free-hanging in-line mounting, push-pull fastening, keyed orientation, shielded construction, and -55°C to 105°C operating temperature range. The primary distinction is product status (active versus obsolete) and regulatory compliance (RoHS3 compliant versus non-compliant).

Q: What are the key differences between the 9-212437-1 and the 1170000000?

A: The 9-212437-1 is a complete plug housing assembly, while the 1170000000 is an insert-only component requiring separate shell procurement. The 9-212437-1 features DIN 240-degree shell size and shielded construction; the 1170000000 uses M23-6 shell size and unshielded construction. The 1170000000 operates across an extended temperature range (-40°C to 125°C) compared to the 9-212437-1 (-55°C to 105°C). These differences preclude direct substitution without design modification.

Q: Are there packaging considerations when transitioning from 212437-4 to 9-212437-1?

A: The 9-212437-1 is supplied in bulk packaging, whereas the 212437-4 packaging specification is not provided in available documentation. Bulk packaging typically accommodates standard procurement workflows. Inventory availability differs: 1717 pieces of 9-212437-1 are in stock compared to 699 pieces of the obsolete 212437-4.

Q: Does the 1170000000 require additional components for installation?

A: Yes. The 1170000000 is an insert-only component that requires a separate shell assembly for complete connector functionality. This introduces additional procurement, assembly, and integration steps not required with the 9-212437-1 plug housing assembly.

Q: What regulatory compliance differences exist between these components?

A: The 212437-4 is RoHS non-compliant. The 9-212437-1 achieves RoHS3 compliance. The 1170000000 is RoHS compliant. For applications subject to RoHS regulations, the 9-212437-1 or 1170000000 are required; the obsolete 212437-4 does not meet current regulatory standards.
