AT04-2P-SS01 Equivalent & Substitute Parts

Part Overview

The AT04-2P-SS01 is a 2-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 free-hanging, in-line mounting with crimp contact termination. The part is actively produced and maintains full RoHS3 compliance with REACH unaffected status.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate access to alternative manufacturers' equivalent products. Substitutes maintain functional and mechanical compatibility through matching electrical specifications, connector geometry, and environmental performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-2P-SS01 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Matching Criteria:

• Connector type (Receptacle)
• Contact type (Male Pin)
• Number of positions (2)
• Number of rows (1)
• Mounting configuration (Free Hanging, In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Latch Holder)
• Housing color (Gray)
• Operating temperature range (-55°C ~ 125°C)
• Regulatory compliance (RoHS3, REACH Unaffected)

The DT04-2P-C017 manufactured by TE Connectivity Deutsch Connectors satisfies all substitution criteria. Both parts maintain identical connector architecture, electrical interface specifications, and environmental performance ratings. The substitute part is actively produced and maintains equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-2P-SS01 and DT04-2P-C017 are active production parts with full regulatory compliance. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

AT04-2P-SS01 (Amphenol Sine Systems Corp): Primary selection when Amphenol sourcing is specified or preferred. Current inventory: 1697 pieces. Maintains RoHS3 compliance and REACH unaffected status. Moisture sensitivity level MSL 1 (Unlimited).

DT04-2P-C017 (TE Connectivity Deutsch Connectors): Direct substitute when Amphenol supply is constrained. Current inventory: 2437 pieces. Maintains RoHS3 compliance and REACH unaffected status. Enhanced sealing specifications (IP68, IP6K9K) with sealed gasket design. Insulation material specified as glass-filled polyamide (PA66/Nylon 6/6).

Both parts are classified under ECCN EAR99 for export control purposes. Selection does not require design modification or re-qualification when substituting between these part numbers within the same application.

Frequently Asked Questions (FAQ)

Q: Can DT04-2P-C017 be used as a direct replacement for AT04-2P-SS01?

A: Yes. Both parts are 2-position rectangular connector receptacles with identical connector type, contact configuration, mounting method, and operating temperature range. No design changes are required for substitution.

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

A: The primary differences are in insulation material composition and sealing specifications. The DT04-2P-C017 features glass-filled polyamide (PA66) insulation and enhanced sealing with IP68 and IP6K9K ratings plus sealed gasket design, compared to the AT04-2P-SS01 thermoplastic insulation with cap cover and sealed design.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AT04-2P-SS01 and DT04-2P-C017 are RoHS3 compliant and REACH unaffected.

Q: Do these parts require contacts to be purchased separately?

A: Yes. Both part numbers are connector housings only. Contacts are not included and must be ordered separately according to your application requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C.

Q: Are there any moisture sensitivity considerations?

A: The AT04-2P-SS01 has MSL 1 (Unlimited) rating. The DT04-2P-C017 has MSL Not Applicable. Both parts are suitable for standard handling and storage without special moisture control requirements.

Q: What fastening method do these connectors use?

A: Both parts use latch holder fastening type for secure connection and disconnection.

Q: Can these parts be used in sealed or IP-rated applications?

A: Both parts feature sealed designs. The DT04-2P-C017 provides additional specification with IP68 and IP6K9K ratings and sealed gasket design, making it suitable for higher-protection-level applications.
