AT16-18PC-PM11 Equivalent & Substitute Parts
Part Overview
The AT16-18PC-PM11 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 green thermoplastic insulation material, integrated cap cover, mounting flange, and sealed design. The connector accommodates male pin contacts via crimp termination and operates across the temperature range of -55°C to 125°C. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are necessary when specific color requirements, inventory availability, or application-specific housing aesthetics differ from the primary green specification while maintaining identical electrical and mechanical functionality.

Substitute Part Grouping Explanation
The AT16-18PC-PM11 and its substitute parts form a parametric equivalent group within the PanelMate™ AT series. Substitution is valid based on the following criteria:
All substitute parts maintain identical specifications across the following critical parameters:
- 18-position receptacle housing configuration
- 3-row arrangement
- Male pin contact accommodation
- Panel mount installation method
- Crimp contact termination
- Latch holder fastening mechanism
- Thermoplastic insulation material
- Operating temperature range of -55°C to 125°C
- Cap cover, mounting flange, and sealed features
- ROHS3 compliance and MSL 1 rating
The substitute parts differ only in housing color: AT16-18PB-PM11 (Black), AT16-18PD-PM11 (Brown), and AT16-18PE-PM11 (Gray) versus the primary AT16-18PC-PM11 (Green). Color variation does not affect electrical performance, mechanical compatibility, or environmental ratings. All parts are manufactured by Amphenol Sine Systems Corp and share the same base product number AT16.

Engineering Selection Recommendations
All four parts within this equivalent group maintain Active product status and full ROHS3 compliance with REACH Unaffected designation. Selection between AT16-18PC-PM11, AT16-18PB-PM11, AT16-18PD-PM11, and AT16-18PE-PM11 is determined by application-specific color requirements and inventory availability rather than electrical or mechanical performance criteria.
The AT16-18PE-PM11 (Gray) variant currently maintains the highest inventory level at 1215 pieces. The AT16-18PB-PM11 (Black) variant provides 1078 pieces in stock. The AT16-18PC-PM11 (Green) primary specification maintains 896 pieces available. The AT16-18PD-PM11 (Brown) variant has 842 pieces in inventory.
All parts are suitable for applications requiring 18-position panel-mount receptacle housings with thermoplastic construction, sealed design, and operation across -55°C to 125°C temperature ranges. No performance degradation occurs when substituting between color variants within this group.
Frequently Asked Questions (FAQ)
Q: Can AT16-18PB-PM11, AT16-18PD-PM11, and AT16-18PE-PM11 be used interchangeably with AT16-18PC-PM11?
A: Yes. These parts are parametric equivalents that differ only in housing color. All electrical, mechanical, and environmental specifications are identical. Substitution is valid when color requirements permit.
Q: Are contacts included with these connector housings?
A: No. All parts in this group are housings only. Male pin contacts must be sourced separately and installed via crimp termination.
Q: What is the temperature operating range for all substitute parts?
A: All parts operate across -55°C to 125°C. This range is consistent across AT16-18PC-PM11, AT16-18PB-PM11, AT16-18PD-PM11, and AT16-18PE-PM11.
Q: Do all substitute parts meet the same compliance standards?
A: Yes. All four parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance status is identical across the group.
Q: What is the mounting configuration for these receptacle housings?
A: All parts feature panel mount installation with a mounting flange. The fastening mechanism is a latch holder design. Configuration is consistent across all substitute parts.
Q: How many positions and rows does each housing accommodate?
A: All parts accommodate 18 positions arranged in 3 rows. Position count and row configuration are identical across AT16-18PC-PM11, AT16-18PB-PM11, AT16-18PD-PM11, and AT16-18PE-PM11.
Q: What contact termination method is used?
A: All parts use crimp contact termination. This termination method is standard across the entire substitute group.
Q: Are these housings sealed?
A: Yes. All parts feature sealed design with integrated cap cover and mounting flange. Sealing characteristics are identical across all variants.
