AT04-3P-RD01 Equivalent & Substitute Parts

Part Overview

The AT04-3P-RD01 is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the AT Series™ product line and is designed for applications requiring sealed, free-hanging inline connections with crimp termination. The part is currently in active production status with 1609 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are present, allowing for component interchangeability in applications where the original part number becomes unavailable or when alternative sourcing is required for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-3P-RD01 is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Connector type: Receptacle
• Contact type: Male Pin
• Number of positions: 3
• Contact termination method: Crimp

Mechanical Parameters:

• Number of rows: 2
• Mounting configuration: Free Hanging (In-Line)
• Fastening mechanism: Latch Holder
• Housing color: Gray

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 125°C
• RoHS3 compliance
• REACH unaffected status

The substitute part DT04-3P-C015 meets all critical electrical, mechanical, and environmental parameters required for direct substitution. Both parts share identical connector topology, contact configuration, mounting methodology, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-3P-RD01 and DT04-3P-C015 are active production components with full regulatory compliance. Selection between these parts is based on the following engineering criteria:

AT04-3P-RD01 Selection Factors:

• Primary sourcing option with 1609 units currently in inventory
• Amphenol Sine Systems Corp manufacturing
• Thermoplastic insulation material
• MSL rating of 1 (Unlimited moisture sensitivity)

DT04-3P-C015 Selection Factors:

• Alternative sourcing with 1212 units currently in inventory
• TE Connectivity Deutsch Connectors manufacturing
• Enhanced sealing features: IP68, IP6K9K rated with reduced wire seals
• Polyamide (PA) nylon glass-filled insulation material
• MSL not applicable (enhanced environmental protection)

Both parts satisfy identical electrical and mechanical requirements. The DT04-3P-C015 provides enhanced environmental protection through IP68 and IP6K9K ratings, making it suitable for applications requiring superior sealing performance. The AT04-3P-RD01 remains the standard specification when enhanced sealing is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can DT04-3P-C015 be used as a direct replacement for AT04-3P-RD01?

A: Yes. Both parts share identical connector topology, position count, row configuration, mounting type, contact termination method, and fastening mechanism. Operating temperature ranges and regulatory compliance are equivalent. The DT04-3P-C015 includes additional IP68 and IP6K9K sealing features not present in the AT04-3P-RD01.

Q: What is the difference in insulation material between these parts?

A: The AT04-3P-RD01 uses thermoplastic insulation, while the DT04-3P-C015 uses polyamide (PA) nylon with glass reinforcement. Both materials are suitable for the specified operating temperature range of -55°C to 125°C.

Q: Are contacts included with either part?

A: No. Both the AT04-3P-RD01 and DT04-3P-C015 are housing-only components. Contacts must be sourced separately and are not included in either package.

Q: What does the "Contacts Not Included" specification mean for application design?

A: This indicates that the receptacle housing is supplied without pre-installed contact pins. Contact selection and installation must be performed separately according to the connector series specifications and application requirements.

Q: How do the sealing features of DT04-3P-C015 affect substitution decisions?

A: The IP68 and IP6K9K ratings on the DT04-3P-C015 provide enhanced protection against dust ingress and high-pressure water jets. These features make the DT04-3P-C015 suitable for applications requiring superior environmental sealing. The AT04-3P-RD01 with sealed design remains appropriate for standard sealed connector applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AT04-3P-RD01 and DT04-3P-C015 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: What is the significance of the MSL rating difference?

A: The AT04-3P-RD01 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The DT04-3P-C015 lists MSL as not applicable, reflecting its enhanced environmental protection design that eliminates standard moisture sensitivity classifications.
