AT04-3P-EC01 Equivalent & Substitute Parts

Part Overview

The AT04-3P-EC01 is a 3-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component belongs to the AT Series™ product line and is classified as an active product with full availability. The connector is designed for free-hanging, in-line applications with crimp termination and latch holder fastening. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the primary part is unavailable, discontinued, or when design flexibility permits alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-3P-EC01 are qualified based on strict equivalence of the following critical parameters:

• Connector Type: Receptacle housing
• Contact Type: Male Pin
• Number of Positions: 3-position configuration
• Number of Rows: 2-row arrangement
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Operating Temperature Range: -55°C ~ 125°C minimum
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected status

The DT04-3P-E003 manufactured by TE Connectivity Deutsch Connectors meets all critical substitution criteria. Both parts share identical functional specifications for connector type, position count, row configuration, mounting method, termination style, and fastening mechanism. Both operate within the same temperature range and maintain equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-3P-EC01 and DT04-3P-E003 are active products with current manufacturing status and full regulatory compliance. Selection between these parts is based on application requirements and supply chain considerations:

AT04-3P-EC01 (Amphenol Sine Systems Corp): Select this part when the AT Series™ product line is specified in design documentation or when Amphenol sourcing is required for supply chain continuity. Current inventory: 1192 pieces.

DT04-3P-E003 (TE Connectivity Deutsch Connectors): Select this part as a direct substitute when equivalent functionality is acceptable and TE Connectivity sourcing is preferred. This part provides additional environmental protection ratings (IP68, IP6K9K) beyond the base specification. Current inventory: 1504 pieces.

Both parts satisfy ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The choice between manufacturers does not compromise electrical or mechanical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can DT04-3P-E003 be used as a direct replacement for AT04-3P-EC01?

A: Yes. Both parts are 3-position rectangular connector receptacles with identical contact type, mounting configuration, termination method, and operating temperature range. All critical functional parameters match, enabling direct substitution in applications where the AT04-3P-EC01 is specified.

Q: What is the difference between the insulation materials listed for each part?

A: AT04-3P-EC01 specifies thermoplastic insulation, while DT04-3P-E003 specifies plastic insulation. Both materials are compatible for this connector class and do not affect substitution eligibility. Material selection reflects manufacturer design choices and does not impact electrical or mechanical performance within the stated operating range.

Q: Does DT04-3P-E003 offer additional capabilities?

A: DT04-3P-E003 includes IP68 and IP6K9K environmental protection ratings, which are not listed for AT04-3P-EC01. These ratings indicate enhanced sealing and water resistance. If these protection levels are required by the application, DT04-3P-E003 provides additional environmental performance. If not required, both parts are functionally equivalent.

Q: Are contacts included with either part?

A: No. Both AT04-3P-EC01 and DT04-3P-E003 are connector housings only. Contacts must be sourced separately and are not included with either part.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: AT04-3P-EC01 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. DT04-3P-E003 lists MSL as Not Applicable, which is consistent with connector housing components that do not require moisture-sensitive device precautions. This difference does not affect substitution compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AT04-3P-EC01 and DT04-3P-E003 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for restricted substances in electrical and electronic equipment.

Q: What is the pitch specification for these connectors?

A: Pitch is not specified (listed as "-") for both parts in the provided data. Contact spacing and pin arrangement are determined by the connector series design and the specific contact set used with the housing.
