DX40M-36P Equivalent & Substitute Parts Reference

Part Overview

The DX40M-36P is a 36-position miniature high-density D-Sub plug connector manufactured by Hirose Electric Co., Ltd. This connector features center strip contacts, free-hanging (in-line) mounting, and solder eyelet termination. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained while offering alternative termination methods or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

The DX40M-36P qualifies for substitution with the DX30AM-36P based on the following matching electrical and mechanical parameters:

• Connector Type & Style: Both are plug connectors with center strip contacts
• Position Count & Row Configuration: Both feature 36 positions arranged in 2 rows
• Mounting Configuration: Both are free-hanging (in-line) connectors
• Connector Classification: Both are miniature high-density D-Sub connectors
• Contact Finish: Both utilize gold-plated contacts
• Series Family: Both belong to the DXM series
• Compliance Standards: Both maintain ROHS3 compliance and REACH unaffected status
• Moisture Sensitivity: Both rated at MSL 1 (Unlimited)

The primary difference between these parts is the termination method: DX40M-36P uses solder eyelet termination, while DX30AM-36P uses IDC (Insulation Displacement Contact) termination. This distinction allows selection based on assembly process requirements and PCB design specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the DX40M-36P and DX30AM-36P are active production parts with identical compliance certifications (ROHS3 and REACH unaffected status). Selection between these parts depends on termination method requirements:

• DX40M-36P (Solder Eyelet Termination): Select when solder-based PCB assembly is specified or when eyelet termination is required for mechanical or electrical design constraints.

• DX30AM-36P (IDC Termination): Select when insulation displacement contact termination is compatible with assembly processes or when IDC-based connection methods are preferred.

Both parts maintain identical electrical performance characteristics, contact finish specifications, and environmental compliance ratings. Packaging differences (bulk versus tray) may influence procurement and inventory management decisions but do not affect functional equivalency.

Frequently Asked Questions (FAQ)

Q: Can DX30AM-36P replace DX40M-36P in existing designs?

A: Functional replacement is possible when the design accommodates IDC termination instead of solder eyelet termination. The electrical and mechanical interfaces are equivalent for all other parameters.

Q: What is the primary difference between these two connectors?

A: The termination method differs. DX40M-36P uses solder eyelet termination for wave or reflow soldering processes, while DX30AM-36P uses IDC termination for crimp-based connection methods.

Q: Are both parts RoHS3 compliant?

A: Yes, both DX40M-36P and DX30AM-36P are ROHS3 compliant and REACH unaffected.

Q: Do packaging differences affect connector performance?

A: No. DX40M-36P is supplied in bulk packaging while DX30AM-36P is supplied in tray packaging. Packaging affects logistics and storage but not electrical or mechanical performance.

Q: Are both connectors rated for unlimited moisture exposure?

A: Yes, both parts carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these connectors be used interchangeably in the same socket?

A: Yes, both are plug connectors with identical position counts, row configurations, and miniature high-density form factors, making them mechanically compatible with equivalent socket designs.
