AT06-4S-MM01 Equivalent & Substitute Parts

Part Overview

The AT06-4S-MM01 is a 4-position rectangular connector plug housing manufactured by Amphenol Sine Systems Corp as part of the AT Series™ product line. This connector housing is designed for free-hanging, in-line applications with crimp-terminated female socket contacts and latch lock fastening. The part is currently Active in product status with 1512 pieces available in new original inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative configurations—such as housing color or connector variants—are necessary due to design constraints, availability, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT06-4S-MM01 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 4
• Contact Termination: Crimp
• Fastening Type: Latch Lock

Mechanical Parameters:

• Number of Rows: 2
• Mounting Type: Free Hanging (In-Line)
• Insulation Material: Thermoplastic
• Features: Cap (Cover), Sealed

Environmental & Compliance Parameters:

• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Variable Parameters (Non-Critical for Substitution):

• Housing Color: Gray (main part) vs. Black (substitute)

The identified substitute part AT06-4S-EC01BLK maintains all critical electrical, mechanical, and environmental parameters while differing only in housing color. This substitution is valid when color differentiation is not a functional requirement of the application.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The AT06-4S-MM01 is the specified part number and remains the first choice when gray housing color is required or when no color constraint exists. This part is Active in product status with robust inventory availability (1512 pieces).

Substitute Part Selection: The AT06-4S-EC01BLK is a valid substitute when black housing color is required or preferred. Both parts are Active in product status, ROHS3 Compliant, and REACH Unaffected. The substitute maintains identical electrical and mechanical specifications, ensuring functional compatibility in applications where housing color does not impact circuit performance or system identification requirements.

Compliance Basis: Both parts meet ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. The Moisture Sensitivity Level of 1 (Unlimited) indicates no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can AT06-4S-EC01BLK be used as a direct replacement for AT06-4S-MM01?

A: Yes, AT06-4S-EC01BLK is a direct functional substitute. All electrical, mechanical, and environmental parameters are identical. The only difference is housing color (black versus gray). Substitution is valid when color differentiation is not a functional or identification requirement.

Q: Are the contact positions and pin assignments identical between these parts?

A: Yes. Both parts have 4 positions arranged in 2 rows with identical mounting type (free hanging, in-line), contact type (female socket), and termination method (crimp). Pin assignments and contact spacing are equivalent.

Q: Do both parts require the same contacts?

A: Yes. Both the AT06-4S-MM01 and AT06-4S-EC01BLK are connector housings only. Contacts are not included with either part and must be sourced separately. The same contact specifications apply to both housings.

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, making them suitable for the same thermal environments.

Q: Are there any moisture sensitivity concerns with these parts?

A: No. Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both AT06-4S-MM01 and AT06-4S-EC01BLK are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for restricted substances and environmental compliance.

Q: What is the difference between the base product number AT06-4S and the full part numbers?

A: The base product number AT06-4S identifies the core connector housing design. The full part numbers (AT06-4S-MM01 and AT06-4S-EC01BLK) include suffix codes that specify housing color and connector variant. The base number is used for design reference, while full part numbers are used for procurement and inventory management.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical and mechanical interchangeability is confirmed. If the design specifies gray color for identification or aesthetic purposes, the original AT06-4S-MM01 should be used. If color is not a design constraint, AT06-4S-EC01BLK provides equivalent functionality.
