AT16-18PD-PM15 Equivalent & Substitute Parts

Part Overview

The AT16-18PD-PM15 is an 18-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp as part of the PanelMate™ AT series. This panel-mount receptacle housing features a brown thermoplastic insulation material, three-row configuration, and is designed for crimp contact termination with latch holder fastening. The part is Active in product status and ROHS3 compliant.

Substitute parts are necessary when specific color requirements, inventory availability, or application-specific housing aesthetics differ from the primary specification while maintaining identical electrical and mechanical functionality.

Substitute Part Grouping Explanation

All substitute parts for the AT16-18PD-PM15 maintain identical electrical and mechanical specifications across the following critical parameters:

Number of positions: 18
Number of rows: 3
Connector type: Receptacle
Contact type: Male Pin
Mounting type: Panel Mount
Contact termination: Crimp
Fastening type: Latch Holder
Insulation material: Thermoplastic
Operating temperature range: -55°C ~ 125°C

Engineering Selection Recommendations

All substitute parts listed are Active in product status and maintain ROHS3 compliance and REACH Unaffected certification status. Selection between the AT16-18PD-PM15 and its substitutes should be based on:

Color Requirement: Choose the part number corresponding to the required housing color. Brown (AT16-18PD-PM15), Gray (AT16-18PA-PM15 or AT16-18PE-PM15), Black (AT16-18PB-PM15), or Green (AT16-18PC-PM15).
Inventory Availability: All substitute parts are in stock. AT16-18PA-PM15 offers the highest inventory level at 1273 pieces.
Regulatory Compliance: All parts meet identical compliance requirements (ROHS3, REACH Unaffected, EAR99 ECCN classification).
Environmental Performance: All parts operate across the identical temperature range of -55°C to 125°C with MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to the AT16-18PD-PM15?

A: Yes. All substitute parts maintain identical electrical specifications including 18-position configuration, three-row layout, male pin contact type, crimp termination, and operating temperature range of -55°C to 125°C.

Q: What is the only difference between the AT16-18PD-PM15 and its substitutes?

A: Housing color is the only difference. The AT16-18PD-PM15 features brown insulation, while substitutes are available in gray (AT16-18PA-PM15, AT16-18PE-PM15), black (AT16-18PB-PM15), and green (AT16-18PC-PM15).

Q: Can I use AT16-18PA-PM15 in place of AT16-18PD-PM15 in my application?
