Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT16-18PE-EK02 are identified based on strict parametric equivalence within the AT Series™ connector family. The following parameters must remain constant for a part to qualify as a direct substitute:

• Connector Type: Receptacle
• Contact Type: Male Pin
• Number of Positions: 18
• Number of Rows: 3
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts may vary in color designation, which does not affect electrical or mechanical compatibility. All identified substitutes maintain identical functional specifications and environmental ratings, ensuring interchangeability in applications where the AT16-18PE-EK02 is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AT16-18PE-EK02, AT16-18PA-EK02, and AT16-18PC-EK02—are Active products manufactured by Amphenol Sine Systems Corp within the AT Series™ connector family. Each part maintains full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

The primary distinction between these parts is color designation: AT16-18PE-EK02 and AT16-18PA-EK02 are gray housings, while AT16-18PC-EK02 is a green housing. This color variation does not affect electrical performance, mechanical compatibility, or environmental operating specifications. Selection between these parts should be based on application-specific color coding requirements or inventory availability.

All three parts are currently in active production with substantial inventory levels (1100–1115 pieces), ensuring supply chain reliability for component procurement and replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can AT16-18PA-EK02 and AT16-18PC-EK02 be used interchangeably with AT16-18PE-EK02?

A: Yes. All three parts maintain identical electrical and mechanical specifications, including connector type, position count, row configuration, termination method, and operating temperature range. The only difference is housing color, which does not affect functional compatibility.

Q: Does the color difference between gray and green housings affect performance?

A: No. Color is a visual identifier only and does not impact electrical performance, mechanical fit, or environmental ratings. Selection should be based on application color-coding standards or design requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AT16-18PE-EK02, AT16-18PA-EK02, and AT16-18PC-EK02 are all ROHS3 compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -55°C to 125°C, providing thermal stability for industrial and commercial applications requiring extended temperature performance.

Q: Are contacts included with these connector housings?

A: No. All three parts are housings only. Contacts must be procured separately and installed via crimp termination.

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

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these connectors be used in sealed applications?

A: Yes. All three parts feature sealed, covered designs suitable for applications requiring environmental protection against moisture and contaminants.
