AT04-3P-RJ120 Equivalent & Substitute Parts

Part Overview

The AT04-3P-RJ120 is a 3-position rectangular receptacle connector manufactured by Amphenol Sine Systems Corp. This connector features crimp termination for 14-20 AWG wire, gold-plated contacts, and is designed for free-hanging in-line applications. The part is currently active in production with 1,974 units in stock. Substitute parts are identified when equivalent functional performance is required due to inventory constraints, supply chain considerations, or application-specific requirements while maintaining compatibility with the original design specifications.

Key Parameters

Substitute Part Grouping Explanation

The AT04-3P-RJ120 has been identified as substitutable with the DT04-3P-P006 based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 3
• Contact Type: Male Pin
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Cable Termination: Crimp
• Fastening Type: Latch Holder
• Color: Gray
• RoHS Status: ROHS3 Compliant

These parameters establish the core mechanical and electrical compatibility required for direct substitution in applications designed for the AT04-3P-RJ120.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-3P-RJ120 and DT04-3P-P006 are active products with ROHS3 compliance and identical ECCN and HTSUS classifications. Selection between these parts is based on the following criteria:

AT04-3P-RJ120 Selection:

• Primary choice when Amphenol Sine Systems Corp connector ecosystem is specified
• Preferred when contact finish specifications require gold plating as a primary design requirement
• Suitable for applications requiring discrete wire termination

DT04-3P-P006 Selection:

• Alternative when TE Connectivity Deutsch Connectors supply chain is preferred
• Applicable when additional environmental protection features (IP68, IP6K9K ratings) are required
• Suitable for applications where polyamide nylon glass-filled insulation material is specified
• Operating temperature range of -55°C to 125°C supports extended thermal applications
• Note: Contacts are not included with this housing; contacts must be sourced separately

Both parts maintain identical core mechanical and electrical compatibility for 3-position rectangular receptacle applications with crimp termination and latch holder fastening.

Frequently Asked Questions (FAQ)

Q: Can the DT04-3P-P006 be used as a direct replacement for the AT04-3P-RJ120?

A: The DT04-3P-P006 is mechanically and electrically compatible based on matching connector type, position count, contact type, mounting configuration, termination method, and fastening type. However, the DT04-3P-P006 is a housing-only component with contacts not included, whereas the AT04-3P-RJ120 is a complete connector assembly. Compatibility requires sourcing appropriate contacts separately for the DT04-3P-P006.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Manufacturer source—Amphenol Sine Systems Corp versus TE Connectivity Deutsch Connectors; (2) Contact finish—AT04-3P-RJ120 specifies gold plating while DT04-3P-P006 housing finish is not specified; (3) Environmental ratings—DT04-3P-P006 includes IP68 and IP6K9K protection ratings; (4) Insulation material—DT04-3P-P006 uses polyamide nylon glass-filled material; (5) Assembly status—AT04-3P-RJ120 is a complete assembly while DT04-3P-P006 is housing only.

Q: Are both parts RoHS compliant?

A: Yes, both the AT04-3P-RJ120 and DT04-3P-P006 are ROHS3 compliant.

Q: What wire gauges are supported?

A: The AT04-3P-RJ120 supports 14-20 AWG wire with crimp termination. Wire gauge specifications for the DT04-3P-P006 are not provided in the available data.

Q: What is the operating temperature range?

A: The AT04-3P-RJ120 operating temperature range is not specified in the available data. The DT04-3P-P006 operates from -55°C to 125°C.

Q: Are contacts included with both parts?

A: The AT04-3P-RJ120 is a complete connector assembly with contacts included. The DT04-3P-P006 is a housing component only; contacts are not included and must be sourced separately.
