AT04-4P-SR01ORG Equivalent & Substitute Parts

Part Overview

The AT04-4P-SR01ORG is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp. This component is part of the ATSeries™SR01 product line and is classified as an active product. The housing features a thermoplastic insulation material with integrated strain relief, sealed design meeting IP68 and IP69K ratings, and a protective cap cover. This connector is designed for free-hanging, in-line mounting applications with crimp-type contact termination and latch holder fastening.

Substitute parts are identified when equivalent rectangular connector housings share identical electrical and mechanical specifications while differing only in non-functional attributes such as color. Identifying equivalent parts ensures design flexibility and supply chain continuity without compromising connector performance or system compatibility.

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-SR01ORG are identified based on strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Equivalence:

• Identical connector type (Receptacle)
• Identical number of positions (4)
• Identical number of rows (2)
• Identical contact type (Male Pin)
• Identical contact termination method (Crimp)

Mechanical Equivalence:

• Identical mounting type (Free Hanging, In-Line)
• Identical fastening type (Latch Holder)
• Identical insulation material (Thermoplastic)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical protective features (Cap, IP68, IP69K, Sealed, Strain Relief)

Series and Compliance Equivalence:

• Same series designation (ATSeries™SR01)
• Same base product number (AT04-4P)
• Identical RoHS compliance status (ROHS3 Compliant)

Parts that differ only in housing color are classified as parametric equivalents. The AT04-4P-SR01ORG (orange housing) and AT04-4P-SR01GRY (gray housing) meet all substitution criteria and are functionally interchangeable in applications where housing color is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

Both the AT04-4P-SR01ORG and AT04-4P-SR01GRY are active products with identical electrical and mechanical specifications. Selection between these parts is determined by application requirements and design constraints.

AT04-4P-SR01ORG (Orange Housing):

• 944 units in stock
• Suitable for applications where orange housing color is specified or preferred for visual identification
• Maintains full compliance with ROHS3 and REACH requirements

AT04-4P-SR01GRY (Gray Housing):

• 1094 units in stock
• Suitable for applications where gray housing color is specified or preferred for visual identification
• Maintains full compliance with ROHS3 and REACH requirements
• Note: Contacts not included in this variant

Both parts are rated for operating temperatures from -55°C to 125°C and provide sealed, IP68/IP69K-rated protection with integrated strain relief. The choice between orange and gray housing does not affect electrical performance, mechanical compatibility, or environmental protection ratings.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-SR01ORG and AT04-4P-SR01GRY electrically interchangeable?

A: Yes. Both parts are electrically identical. They share the same 4-position receptacle configuration, male pin contact type, crimp termination method, and operating temperature range of -55°C to 125°C.

Q: What is the primary difference between these two connector housings?

A: The primary difference is housing color. The AT04-4P-SR01ORG features an orange housing, while the AT04-4P-SR01GRY features a gray housing. All other specifications, including electrical performance, mechanical design, and environmental ratings, are identical.

Q: Can I substitute AT04-4P-SR01GRY for AT04-4P-SR01ORG in my application?

A: Substitution is possible if housing color is not a design requirement. Both parts provide identical connector functionality, IP68/IP69K sealing, strain relief, and latch holder fastening. Verify that your application does not specify a particular housing color for identification or compliance purposes.

Q: Are both parts ROHS3 compliant?

A: Yes. Both AT04-4P-SR01ORG and AT04-4P-SR01GRY are ROHS3 compliant and REACH unaffected.

Q: What does "Contacts Not Included" mean for the AT04-4P-SR01GRY?

A: This notation indicates that the gray housing variant is supplied as a housing component only, without pre-installed crimp contacts. Contacts must be sourced separately and installed using the crimp termination method specified for this connector series.

Q: Do both parts support the same mounting configuration?

A: Yes. Both parts are designed for free-hanging, in-line mounting with latch holder fastening. The mechanical mounting interface and fastening mechanism are identical.

Q: What environmental protection do these connectors provide?

A: Both parts provide IP68 and IP69K ratings with sealed design and integrated strain relief. These ratings ensure protection against dust ingress and high-pressure water jets, making them suitable for harsh industrial environments.
