AT04-2P-MM01 Equivalent & Substitute Parts Reference

Part Overview

The AT04-2P-MM01 is a 2-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp, part of the AT Series™ product line. This connector is designed for applications requiring free-hanging, in-line mounting with crimp termination and latch holder fastening. The housing is gray thermoplastic with sealed design and cap cover features. The part is currently active in production with 1495 units in stock inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to supply constraints, inventory availability, or design standardization across multiple connector families.

Substitute Part Grouping Explanation

The AT04-2P-MM01 and DT04-2P-CE01 are classified as direct substitutes based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Connector Type: Both are receptacle housings
• Contact Type: Both accept male pins
• Number of Positions: Both accommodate 2 positions
• Number of Rows: Both feature single-row configuration
• Mounting Type: Both are free-hanging, in-line designs
• Contact Termination: Both use crimp termination
• Fastening Type: Both employ latch holder fastening
• Color: Both are gray
• Operating Temperature Range: Both operate -55°C ~ 125°C
• RoHS Compliance: Both are ROHS3 compliant
• REACH Status: Both are REACH unaffected

These parameters establish the substitution basis. The DT04-2P-CE01 provides enhanced sealing features (IP68, IP6K9K, Reduced Wire Seals) compared to the standard sealed design of the AT04-2P-MM01, making it suitable for applications requiring higher environmental protection while maintaining all core functional requirements.

Parameter Comparison

Engineering Selection Recommendations

AT04-2P-MM01 Selection Criteria:

• Primary choice when standard sealed design meets application requirements
• Preferred for applications with unlimited moisture sensitivity tolerance (MSL 1)
• Suitable for standard environmental conditions within -55°C to 125°C operating range
• ROHS3 compliance satisfies regulatory requirements for restricted substance control
• Active product status ensures continued availability and supply chain stability

DT04-2P-CE01 Selection Criteria:

• Alternative selection when enhanced environmental sealing is required (IP68, IP6K9K ratings)
• Applicable for applications requiring reduced wire seals for improved moisture ingress protection
• Maintains identical electrical and mechanical interface compatibility
• ROHS3 compliance and REACH unaffected status provide equivalent regulatory compliance
• Active product status with 990 units in inventory supports production requirements

Both parts satisfy identical core functional requirements and are interchangeable at the housing level. Selection between AT04-2P-MM01 and DT04-2P-CE01 depends on specific environmental protection requirements and sealing specifications demanded by the end application.

Frequently Asked Questions (FAQ)

Q: Are AT04-2P-MM01 and DT04-2P-CE01 directly interchangeable?

A: Yes, both parts are direct substitutes. They share identical connector type, position count, mounting configuration, termination method, and fastening mechanism. The primary difference is enhanced sealing features in the DT04-2P-CE01 (IP68, IP6K9K ratings), which provides superior environmental protection while maintaining full mechanical and electrical compatibility.

Q: What does the "2POS" designation indicate?

A: The "2POS" designation specifies that the connector housing accommodates 2 contact positions. Both the AT04-2P-MM01 and DT04-2P-CE01 are configured for 2-position applications.

Q: Are contacts included with these housings?

A: No. Both the AT04-2P-MM01 and DT04-2P-CE01 are supplied as housings only. Contacts must be sourced separately and installed using the crimp termination method.

Q: What is the significance of the "Sealed" and "IP68/IP6K9K" features?

A: The AT04-2P-MM01 provides standard sealing with cap cover protection. The DT04-2P-CE01 provides enhanced sealing with IP68 rating (protection against temporary immersion) and IP6K9K rating (protection against high-pressure water jets), plus reduced wire seals for improved moisture barrier performance. Selection depends on environmental exposure requirements.

Q: Do both parts support the same operating temperature range?

A: Yes. Both AT04-2P-MM01 and DT04-2P-CE01 operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: What is the difference between "Thermoplastic" and "Plastic" insulation materials?

A: Both materials serve the insulation function in these connector housings. The AT04-2P-MM01 specifies thermoplastic material, while the DT04-2P-CE01 specifies plastic. Both materials are suitable for the specified operating temperature range and provide equivalent electrical insulation properties for this connector category.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AT04-2P-MM01 and DT04-2P-CE01 are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for restricted substance control and chemical safety.

Q: What does MSL 1 (Unlimited) mean for the AT04-2P-MM01?

A: MSL 1 indicates Moisture Sensitivity Level 1, which means unlimited floor life. The component can be stored indefinitely without special moisture control measures before assembly, making it suitable for standard warehouse and manufacturing environments without requiring desiccant packaging or controlled humidity storage.
