Substitute Part Grouping Explanation

Substitution eligibility for the AT04-4P-SR02GRN is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Connector type (Receptacle), contact type (Male Pin), number of positions (4), number of rows (2), contact termination method (Crimp), and fastening mechanism (Latch Holder) must remain identical.

Environmental & Mechanical Specifications: Operating temperature range (-55°C ~ 125°C), protective features (Cap/Cover, IP68, IP69K ratings, Reduced Wire Seals, Strain Relief), insulation material (Thermoplastic), and mounting configuration (Free Hanging In-Line) must be preserved.

Compliance & Regulatory: RoHS3 compliance, REACH unaffected status, and ECCN classification (EAR99) must match.

Variable Parameters: Housing color is the only parameter permitted to vary among substitute parts within this grouping. All substitute parts maintain the same base product number (AT04-4P) and series designation (ATSeries™SR02).

Engineering Selection Recommendations

Both the AT04-4P-SR02GRN and AT04-4P-SR02GRY maintain Active product status with full regulatory compliance. Selection between these parts should be based on application requirements and availability:

AT04-4P-SR02GRN (Green Housing): Current inventory of 1092 pieces. Select this part when green color coding is specified for circuit identification, wiring harness organization, or system documentation standards.

AT04-4P-SR02GRY (Gray Housing): Current inventory of 1482 pieces. Select this part when gray color coding is required or when higher stock availability is a priority. Note that contacts are not included with this substitute part.

Both parts deliver identical electrical performance, environmental protection (IP68/IP69K), and operational reliability across the full temperature range (-55°C to 125°C). The choice between green and gray housing does not affect functional compatibility or system performance.

Frequently Asked Questions (FAQ)

Q: Are AT04-4P-SR02GRN and AT04-4P-SR02GRY electrically interchangeable?

A: Yes. Both parts are electrically identical with 4 positions, 2 rows, male pin contacts, crimp termination, and latch holder fastening. Housing color is the only difference.

Q: Do these parts maintain the same environmental protection ratings?

A: Yes. Both parts feature identical IP68 and IP69K ratings, cap/cover protection, reduced wire seals, and strain relief. Operating temperature range is -55°C to 125°C for both.

Q: What is the significance of the housing color difference?

A: Housing color serves application-specific purposes such as circuit identification, wiring harness organization, or compliance with system color-coding standards. The color variation does not affect electrical or mechanical performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AT04-4P-SR02GRN and AT04-4P-SR02GRY are ROHS3 compliant and REACH unaffected.

Q: What is the difference in inventory availability?

A: AT04-4P-SR02GRN has 1092 pieces in stock, while AT04-4P-SR02GRY has 1482 pieces in stock. The gray variant offers higher current availability.

Q: Are contacts included with both parts?

A: The AT04-4P-SR02GRN specification indicates contacts are included. The AT04-4P-SR02GRY specification notes that contacts are not included. Verify contact requirements for your application.

Q: Can these parts be used in the same mounting configuration?

A: Yes. Both parts use identical free-hanging in-line mounting with latch holder fastening. They are mechanically interchangeable in this regard.

Q: What is the base product number for both parts?

A: Both parts share the base product number AT04-4P and belong to the ATSeries™SR02 product line.
