TE Connectivity AMP Connectors 9-212437-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 9-212437-0 is a 5-position circular connector plug housing designed for male pins with free-hanging (in-line) mounting. This component features a DIN 180-degree shell size, push-pull fastening, and keyed orientation for secure mating. The connector is constructed with a brass shell finished in tin and incorporates a shielded design with a polyamide nylon glass-filled insert. The part is currently active in production status with 782 pieces available in new original inventory.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications requiring alternative fastening mechanisms or environmental protection ratings while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 9-212437-0 are identified based on the following core compatibility parameters:

Primary Matching Criteria:

• Number of Positions: 5
• Connector Type: Plug with Male Pins
• Mounting Type: Free Hanging (In-Line)
• Orientation: Keyed
• Contact Termination: Crimp-compatible
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitution Scope: The identified substitute parts (EN2C5M26G1 and EN2C5M26DCW) from Switchcraft Inc. maintain the core functional requirements of a 5-position circular connector plug with male pins, keyed orientation, and free-hanging mounting. Both substitutes support crimp or solder cup termination, ensuring compatibility with existing contact assemblies. The substitutes differ in fastening mechanism (bayonet lock versus push-pull), shell material composition, and environmental protection ratings, which may be advantageous in specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (9-212437-0): The TE Connectivity AMP Connectors 9-212437-0 remains the primary specification when push-pull fastening, shielded design, and extended operating temperature range (-55°C to 105°C) are required. This part is ROHS3 compliant and maintains unlimited moisture sensitivity rating, suitable for demanding industrial and aerospace applications.

Substitute Selection (EN2C5M26G1 or EN2C5M26DCW): The Switchcraft EN2™ series substitutes (EN2C5M26G1 and EN2C5M26DCW) are applicable when:

• Bayonet lock fastening is acceptable or preferred over push-pull mechanism
• Enhanced ingress protection (IP66/IP67/IP68) is required for marine, medical, or harsh environmental applications
• Unshielded design is compatible with the application circuit requirements
• Operating temperature range of -40°C to 85°C meets application specifications

Both Switchcraft substitutes are ROHS3 compliant with MSL 1 rating and support crimp or solder cup termination, ensuring compatibility with existing contact assemblies. The EN2C5M26G1 variant specifies cable opening dimensions (0.100" ~ 0.140"), while EN2C5M26DCW includes winged features for enhanced handling.

Frequently Asked Questions (FAQ)

Q: Can EN2C5M26G1 or EN2C5M26DCW directly replace 9-212437-0 in existing assemblies?

A: Direct mechanical replacement is possible due to matching 5-position configuration, keyed orientation, and free-hanging mounting. However, the fastening mechanism differs (bayonet lock versus push-pull), requiring mating connector compatibility verification. Unshielded design of Switchcraft parts may require circuit-level evaluation if EMI/RFI performance is critical.

Q: What is the primary difference between EN2C5M26G1 and EN2C5M26DCW?

A: Both parts are functionally equivalent 5-position circular connector plugs with identical electrical and mechanical specifications. EN2C5M26DCW includes winged features and coupling nut for enhanced assembly handling. EN2C5M26G1 specifies cable opening dimensions (0.100" ~ 0.140"). Selection depends on cable assembly requirements and handling preferences.

Q: Are the Switchcraft substitutes suitable for high-temperature applications?

A: The Switchcraft EN2™ series operates within -40°C to 85°C range, which is narrower than the TE Connectivity 9-212437-0 range (-55°C to 105°C). Applications requiring operation below -40°C or above 85°C must retain the primary TE Connectivity specification.

Q: Do the substitute parts maintain shielding characteristics?

A: No. The Switchcraft EN2C5M26G1 and EN2C5M26DCW are unshielded designs, whereas the 9-212437-0 features shielded construction. Applications requiring electromagnetic shielding must use the primary TE Connectivity part or verify circuit tolerance to unshielded configuration.

Q: What environmental protection does each part provide?

A: The 9-212437-0 does not specify ingress protection rating. The Switchcraft substitutes provide IP66/IP67/IP68 protection (dust tight, water resistant, waterproof), making them suitable for marine, medical, and harsh industrial environments where moisture and particulate ingress protection is required.

Q: Are all three parts RoHS compliant?

A: Yes. The 9-212437-0, EN2C5M26G1, and EN2C5M26DCW are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, suitable for regulated manufacturing environments.

Q: What termination options are available?

A: The 9-212437-0 supports crimp termination. Both Switchcraft substitutes support crimp or solder cup termination, providing additional flexibility for contact assembly methods.
