AT06-4S-EC01 Rectangular Connector Plug Housing - Equivalent & Substitute Parts

Part Overview

The AT06-4S-EC01 is a 4-position rectangular connector plug housing manufactured by Amphenol Sine Systems Corp, classified within the AT Series™ product line. This connector housing is designed for crimp-terminated female socket contacts with a latch lock fastening mechanism and operates across an industrial temperature range of -55°C to 125°C. The part is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). This connector housing is supplied without contacts; contacts must be procured separately and crimped into the housing. Substitute parts are identified when equivalent electrical and mechanical parameters are required but the original part becomes unavailable or inventory constraints necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector plug housings is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Plug)
• Contact type (Female Socket)
• Number of positions (4)
• Row configuration (2 rows)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Lock)

Environmental & Operational Parameters:

• Operating temperature range (-55°C to 125°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

Mechanical Parameters:

• Mounting configuration (Free Hanging In-Line)

The substitute part DT06-4S-E003 satisfies all critical substitution criteria. Both housings accommodate identical position counts, row arrangements, and termination methods. Both operate within the same temperature envelope and maintain equivalent regulatory compliance status. The primary distinction between the main part and substitute is the housing color (Gray versus Black) and the addition of IP68/IP6K9K ingress protection ratings on the substitute, which represent enhanced environmental sealing capabilities that do not preclude interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the AT06-4S-EC01 and DT06-4S-E003 are active production parts with current manufacturing status and full regulatory compliance. Selection between these two housings should be based on the following engineering considerations:

AT06-4S-EC01 Selection Criteria:

• Primary sourcing option when Amphenol AT Series™ standardization is required
• Gray housing color specification for visual identification or assembly documentation
• Standard environmental sealing requirements

DT06-4S-E003 Selection Criteria:

• Alternative sourcing when TE Connectivity Deutsch connector ecosystem is preferred
• Black housing color specification for visual identification or assembly documentation
• Enhanced environmental sealing (IP68, IP6K9K) required for applications with elevated moisture or pressure jet exposure
• Inventory availability or lead time advantages

Both parts maintain identical electrical and mechanical interface specifications, ensuring direct substitution capability without circuit redesign or connector pin reconfiguration. The choice between these housings does not affect contact compatibility, as both accept the same crimp-terminated female socket contacts and maintain identical position geometry and row spacing.

Frequently Asked Questions (FAQ)

Q: Can DT06-4S-E003 be used as a direct replacement for AT06-4S-EC01 in existing assemblies?

A: Yes. Both housings are mechanically and electrically equivalent across all critical parameters: 4-position, 2-row configuration, crimp termination, latch lock fastening, and identical operating temperature range. The housings accept the same contact types and maintain equivalent regulatory compliance. Housing color and enhanced ingress protection on the substitute do not preclude direct substitution.

Q: What is the significance of the IP68 and IP6K9K ratings on the DT06-4S-E003?

A: IP68 indicates dust-tight operation and continuous submersion capability. IP6K9K indicates resistance to high-pressure water jets. These ratings represent enhanced environmental sealing on the substitute part. If the application does not require these enhanced protections, the standard AT06-4S-EC01 remains functionally equivalent.

Q: Are contacts included with either housing?

A: No. Both AT06-4S-EC01 and DT06-4S-E003 are supplied as housings only. Contacts must be procured separately and crimped into the housing using appropriate crimp tooling. Contact specifications must match the 4-position, female socket configuration.

Q: Do these housings differ in pitch or row spacing?

A: No pitch or row spacing values are specified in the product data for either housing, indicating these parameters are standardized within their respective series. Both housings maintain identical mechanical geometry for the 2-row, 4-position configuration.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: AT06-4S-EC01 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. DT06-4S-E003 is listed as Not Applicable for MSL, consistent with its plastic housing construction. Both parts can be stored and handled without desiccant packaging requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both AT06-4S-EC01 and DT06-4S-E003 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations for industrial applications.
