Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-BLU are identified based on strict parametric equivalence within the AT Series™ rectangular connector family. All substitute parts maintain identical electrical and mechanical specifications with the exception of housing color. The substitution logic is based on the following key parameters that remain constant across all equivalent parts:

• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 4
• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Features: Sealed
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Base Product Number: AT04-4P
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The only variable parameter across the substitute family is the housing color. Color variants are provided to support circuit identification schemes, wire harness organization standards, and system-level design requirements where color coding is used to distinguish signal types or functional groups.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by Amphenol Sine Systems Corp and maintain full compliance with ROHS3 and REACH regulations. Each part carries identical electrical and mechanical specifications, with color differentiation as the sole variable. Selection among these equivalent parts should be based on application-specific color coding requirements or circuit identification standards.

All substitute parts are packaged in boxes and carry unlimited moisture sensitivity level (MSL 1), indicating no special storage or handling requirements beyond standard component management practices. The sealed feature is consistent across all variants, providing equivalent environmental protection for all color options.

Inventory availability varies across color options, with AT04-4P-BRN maintaining the highest stock level at 1929 pieces and AT04-4P-YEL the lowest at 1065 pieces. The primary part AT04-4P-BLU maintains 1657 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Are all AT04-4P color variants electrically and mechanically identical?

A: Yes. All AT04-4P color variants maintain identical electrical and mechanical specifications. The housing color is the only differentiating parameter. All variants feature 4 positions, 2 rows, crimp termination, latch holder fastening, sealed construction, and identical operating temperature ranges.

Q: Can AT04-4P-BLU be directly replaced with any other AT04-4P color variant?

A: Yes, from an electrical and mechanical standpoint. All AT04-4P variants are parametrically equivalent. Selection of a specific color variant should be based on application requirements for circuit identification, wire harness organization, or system design standards that utilize color coding.

Q: What is the significance of the base product number AT04-4P?

A: The base product number AT04-4P identifies the core connector housing design. The suffix (such as -BLU, -RED, -GRN) designates the color variant. All parts sharing the AT04-4P base number are functionally equivalent within the AT Series™ rectangular connector family.

Q: Are contacts included with these connector housings?

A: No. All AT04-4P variants are housings only. Contacts are not included and must be sourced separately. The crimp termination type indicates that contacts are designed for crimp-style wire attachment.

Q: What compliance certifications apply to all AT04-4P variants?

A: All variants are ROHS3 compliant and REACH unaffected. These certifications are consistent across the entire color family, ensuring regulatory compliance for applications subject to these standards.

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

A: All AT04-4P variants carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special dry storage or handling procedures related to moisture exposure.

Q: How does the sealed feature affect connector performance?

A: The sealed feature provides environmental protection by preventing moisture and contaminants from entering the connector housing. This sealed construction is consistent across all color variants and supports applications requiring environmental protection.
