DCM37SH D-Sub 37 Position Receptacle Connector

Part Overview

The DCM37SH is a 37 position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel mount, through-hole solder applications. This connector features female sockets in a 2-row configuration with shell size 4 (DC, C) layout. The part is currently active in production with 700 units in stock. Alternative equivalent parts are available from other manufacturers to support procurement flexibility, supply chain continuity, and specific application requirements such as RoHS compliance or military specification adherence.

Key Parameters

Substitute Part Grouping Explanation

Equivalent substitution for the DCM37SH is determined by strict adherence to the following core parameters:

• Connector Configuration: 37 position, 2-row D-Sub receptacle with female sockets
• Shell Size and Layout: Size 4 (DC, C) configuration
• Mounting and Termination: Panel mount, through-hole solder termination
• Electrical Performance: 5.0A to 7.5A current rating, gold-plated contacts, signal contact type
• Environmental Compliance: Operating temperature -55°C ~ 125°C, UL94 V-0 flammability rating

The three substitute parts listed below meet these core substitution criteria. Variations in shell material finish (chromate plated zinc versus cadmium plated), dielectric material composition, and RoHS compliance status do not prevent functional equivalence in applications where these specific finishes or compliance certifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

DCM37SH (ITT Cannon, LLC) — Primary selection for applications requiring RoHS compliance and chromate plating. Active product status with 700 units in stock. Suitable for commercial and industrial applications where lead-free and halogen-free requirements are mandated.

M24308/23-10F (Amphenol Interconnect India) — Military specification equivalent (MIL-C-24308) with active product status and 665 units in stock. Recommended for defense, aerospace, and high-reliability applications. Cadmium plating provides enhanced corrosion resistance in harsh environments. RoHS non-compliant; verify compliance requirements before selection. Contact finish thickness specified at 10.0µin (0.25µm).

M24308/23-4F (TE Connectivity Aerospace, Defense and Marine) — Military specification equivalent (MIL-DTL-24308) with active product status and highest inventory availability (1314 units). Suitable for military and aerospace applications. Current rating reduced to 5A; verify adequacy for application requirements. Cadmium plating and brass contact material. RoHS non-compliant; REACH affected. Contact finish thickness specified at 10.0µin (0.25µm).

628-037-220-041 (Mercury United Electronics, Inc.) — Commercial equivalent with 991 units in stock. Metal shell construction. Limited technical specification data available; recommend verification of dielectric material, flammability rating, and current rating before final selection.

Frequently Asked Questions (FAQ)

Q: Can M24308/23-4F substitute for DCM37SH in a commercial application?

A: Functional substitution is possible based on connector configuration, position count, and operating temperature range. However, M24308/23-4F has a reduced current rating of 5A versus DCM37SH at 7.5A. Verify that your application current requirements do not exceed 5A. Additionally, M24308/23-4F is RoHS non-compliant; confirm that your application does not mandate RoHS compliance.

Q: What is the difference between chromate and cadmium plating on the shell?

A: Both finishes provide corrosion resistance on steel shells. Chromate plating (DCM37SH) is RoHS-compliant and suitable for commercial applications. Cadmium plating (M24308 series) offers enhanced corrosion resistance in harsh environments and is specified in military standards but is RoHS non-compliant due to cadmium content restrictions.

Q: Are all substitute parts suitable for panel mount applications?

A: DCM37SH, M24308/23-10F, and M24308/23-4F are specified for panel mount or through-hole mounting. 628-037-220-041 is specified as vertical mount; confirm mechanical compatibility with your panel mounting requirements before selection.

Q: What is the significance of the contact finish thickness specification?

A: Contact finish thickness (10.0µin / 0.25µm) specified for M24308/23-10F and M24308/23-4F indicates gold plating depth. This specification ensures consistent electrical contact resistance and durability over the connector's operational life. DCM37SH does not specify thickness; contact the manufacturer for this parameter if critical to your application.

Q: Can I use M24308/23-4F if my application requires 7.5A current?

A: No. M24308/23-4F is rated for 5A maximum current. Using it in a 7.5A application exceeds the rated current capacity and may result in connector overheating, contact degradation, or failure. Select DCM37SH or M24308/23-10F, both rated at 7.5A.

Q: What inventory quantities are available for each part?

A: DCM37SH: 700 units; 628-037-220-041: 991 units; M24308/23-10F: 665 units; M24308/23-4F: 1314 units. Verify current availability with your supplier before finalizing procurement.
