AT04-4P-EC01BLK Equivalent & Substitute Parts

Part Overview

The AT04-4P-EC01BLK is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the AT Series™ product line and is classified as an active product. The housing accommodates male pin contacts with crimp termination and features a latch holder fastening mechanism. This connector is designed for free-hanging, in-line mounting applications requiring a sealed, covered receptacle interface.

Substitute parts are identified when equivalent rectangular connector housings share identical or compatible electrical and mechanical specifications, including connector type, position count, contact termination method, fastening mechanism, operating temperature range, and compliance certifications. Availability of substitute parts ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-EC01BLK are identified based on strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Male Pin)
• Number of positions (4)
• Contact termination method (Crimp)
• Operating temperature range (-55°C ~ 125°C)

Mechanical Compatibility Parameters:

• Number of rows (2)
• Mounting type (Free Hanging, In-Line)
• Fastening type (Latch Holder)
• Color (Black)

Regulatory Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status
• ECCN classification (EAR99)

The substitute part DT04-4P-E005 manufactured by TE Connectivity Deutsch Connectors meets all critical electrical and mechanical parameters. This part maintains identical position count, contact configuration, termination method, fastening mechanism, and operating temperature specifications. Both parts are active products with current manufacturing status and equivalent regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-EC01BLK and DT04-4P-E005 are active products with current manufacturing status and equivalent regulatory compliance. Selection between these parts is based on application-specific requirements and availability.

AT04-4P-EC01BLK (Amphenol Sine Systems Corp):

• Primary specification for AT Series™ applications
• Thermoplastic insulation material
• Standard environmental protection via cap cover
• Current inventory: 1372 pieces

DT04-4P-E005 (TE Connectivity Deutsch Connectors):

• Enhanced environmental protection with IP68 and IP6K9K ratings
• Polyamide (PA) nylon with glass-filled insulation material
• Improved mechanical durability characteristics
• Current inventory: 1650 pieces

Both parts maintain identical electrical performance across the specified operating temperature range (-55°C ~ 125°C) and support crimp contact termination with latch holder fastening. The DT04-4P-E005 provides additional environmental sealing specifications suitable for applications requiring enhanced protection against moisture and pressure jets. Selection should be based on environmental exposure requirements and connector series standardization within the target application.

Frequently Asked Questions (FAQ)

Q: Can DT04-4P-E005 be used as a direct replacement for AT04-4P-EC01BLK?

A: Yes. Both parts share identical electrical and mechanical specifications including 4-position configuration, male pin contact type, crimp termination, latch holder fastening, and operating temperature range of -55°C ~ 125°C. Both are ROHS3 compliant and REACH unaffected. The DT04-4P-E005 includes additional IP68 and IP6K9K environmental protection ratings.

Q: What are the key compatibility parameters for rectangular connector substitution?

A: Critical parameters include connector type (receptacle), contact type (male pin), number of positions (4), number of rows (2), mounting type (free hanging in-line), contact termination method (crimp), fastening type (latch holder), and operating temperature range (-55°C ~ 125°C). Regulatory compliance status (RoHS3, REACH) must also be equivalent.

Q: Are contacts included with these connector housings?

A: No. Both AT04-4P-EC01BLK and DT04-4P-E005 are connector housings only. Male pin contacts must be sourced separately and are not included with the housing.

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

A: The AT04-4P-EC01BLK uses thermoplastic insulation, while the DT04-4P-E005 uses polyamide (PA) nylon with glass-filled composition. Both materials support the identical operating temperature range and are suitable for crimp contact applications.

Q: Do both parts support the same environmental protection level?

A: The AT04-4P-EC01BLK provides standard environmental protection via a cap cover. The DT04-4P-E005 provides enhanced environmental protection with IP68 and IP6K9K ratings, indicating higher resistance to moisture ingress and pressure jet exposure.

Q: What is the pitch specification for these connectors?

A: Pitch specification is not provided for either part in the available technical documentation.

Q: Are there any differences in regulatory compliance between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Compliance status is equivalent.
