Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-4P-MM01 is determined by the following critical parameters:

Core Compatibility Parameters:

• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 4
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Compliance: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute part DT04-4P-CE01 manufactured by TE Connectivity Deutsch Connectors meets all core compatibility parameters. Both parts are 4-position receptacle housings with identical mounting, termination, and environmental specifications. The primary difference lies in enhanced sealing features and insulation material composition in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both AT04-4P-MM01 and DT04-4P-CE01 are Active products with full regulatory compliance. Selection between these parts should be based on the following criteria:

AT04-4P-MM01 Selection:

• Standard sealed rectangular connector applications
• Thermoplastic insulation material requirements
• Moisture Sensitivity Level 1 (Unlimited) handling capability
• ROHS3 and REACH compliance required

DT04-4P-CE01 Selection:

• Applications requiring enhanced environmental sealing (IP68, IP6K9K ratings)
• Polyamide (PA) nylon glass-filled insulation material compatibility
• Reduced wire seal configurations
• ROHS3 and REACH compliance required

Both parts maintain identical core electrical and mechanical specifications, including 4-position configuration, crimp termination, latch holder fastening, and -55°C to 125°C operating temperature range. The choice between manufacturers and specific feature sets depends on application-specific environmental and material requirements.

Frequently Asked Questions (FAQ)

Q: Can DT04-4P-CE01 be used as a direct replacement for AT04-4P-MM01?

A: Yes. Both parts share identical core specifications: 4-position receptacle housing, male pin contacts, crimp termination, latch holder fastening, free-hanging in-line mounting, and -55°C to 125°C operating temperature range. Both are ROHS3 compliant and REACH unaffected.

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

A: The primary differences are insulation material composition (Thermoplastic versus Polyamide/Nylon Glass Filled) and sealing features. The DT04-4P-CE01 includes IP68 and IP6K9K ratings with reduced wire seals, while the AT04-4P-MM01 provides standard sealed design.

Q: Are contacts included with these connector housings?

A: No. Both AT04-4P-MM01 and DT04-4P-CE01 are supplied as housings only. Contacts must be sourced separately and are not included in the package.

Q: What is the significance of the 2-row configuration?

A: The 2-row configuration indicates the internal arrangement of the 4 positions within the housing. This affects the physical layout and mating interface of the connector assembly.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both AT04-4P-MM01 and DT04-4P-CE01 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for industrial and commercial applications.

Q: What wire gauge range is supported?

A: The AT04-4P-MM01 supports 14-20 AWG wire gauges. This specification applies to the housing design and crimp termination capability.

Q: Can these parts be used interchangeably in existing assemblies?

A: Interchangeability depends on specific application requirements regarding insulation material, sealing performance, and environmental exposure. Both parts maintain identical connector interface specifications and mounting characteristics.
