SMS18PDH1NA Equivalent & Substitute Parts Reference

Part Overview

The SMS18PDH1NA is an 18-position rectangular connector housing manufactured by Souriau-Sunbank by Eaton. This plug housing is designed for applications requiring a 0.200" (5.08mm) pitch configuration with three rows of contacts. The part is currently in active production status with 1,015 units available in inventory.

Substitute parts are identified when they maintain identical electrical and mechanical parameters within the SMS series, ensuring direct functional equivalence without design modification. The SMS18PDH1NA operates across an industrial temperature range of -40°C to 105°C and complies with ROHS3 and REACH regulations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMS18PDH1NA are identified based on strict equivalence of the following critical parameters:

• Series Designation: SMS series only
• Number of Positions: 18 positions
• Pitch Configuration: 0.200" (5.08mm)
• Number of Rows: 3 rows
• Row Spacing: 0.200" (5.08mm)
• Connector Type: Plug housing
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Latch Lock
• Insulation Material: Polyamide (PA66), Nylon 6/6

The SMS18PDH1 is classified as a parametric equivalent within the SMS rectangular connector family. This substitute maintains all critical electrical and mechanical parameters required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

SMS18PDH1NA is the primary specification part with confirmed ROHS3 compliance and active product status. This part number is recommended for new designs and applications where regulatory compliance documentation is required.

SMS18PDH1 is available as a parametric equivalent with 965 units in stock. This substitute maintains all critical electrical and mechanical parameters. Selection between SMS18PDH1NA and SMS18PDH1 should be based on inventory availability, delivery requirements, and specific compliance documentation needs for the end application.

Both parts are manufactured by Souriau-Sunbank by Eaton within the SMS series and are suitable for applications operating within the -40°C to 105°C temperature range. The choice between these parts does not affect mechanical fit, electrical performance, or functional compatibility within the connector system.

Frequently Asked Questions (FAQ)

Q: Can SMS18PDH1 be used as a direct replacement for SMS18PDH1NA?

A: Yes. Both parts maintain identical electrical and mechanical parameters including 18 positions, 0.200" (5.08mm) pitch, 3-row configuration, crimp termination, and latch lock fastening. The primary difference is the packaging designation suffix and inventory availability.

Q: What does the "NA" suffix in SMS18PDH1NA indicate?

A: The "NA" suffix indicates the specific packaging or regional designation variant. The core SMS18PDH1 base number identifies the fundamental connector housing design. Both SMS18PDH1NA and SMS18PDH1 share the same mechanical and electrical specifications.

Q: Are contacts included with these connector housings?

A: No. Both SMS18PDH1NA and SMS18PDH1 are housings only. Contacts must be ordered separately and crimped into the housing according to the connector system design.

Q: What is the significance of the 3-row configuration with 0.200" (5.08mm) row spacing?

A: The 3-row arrangement with 0.200" (5.08mm) row spacing defines the physical layout of the 18 contact positions. This configuration is fixed for both substitute parts and cannot be altered. Any connector system designed for SMS18PDH1NA will accommodate SMS18PDH1 without modification.

Q: Are there any temperature or environmental limitations for these parts?

A: Both parts operate across -40°C to 105°C. The polyamide (PA66) nylon 6/6 insulation material and moisture sensitivity level 1 (unlimited) rating indicate suitability for standard industrial environments without special environmental protection requirements.

Q: What is the difference between "Bulk" and unspecified packaging?

A: SMS18PDH1NA is specified with "Bulk" packaging, while SMS18PDH1 packaging is not specified in the available data. This distinction relates to order quantity and delivery format but does not affect the connector housing specifications or performance characteristics.
