DCMM-37S D-Sub Receptacle Connector Equivalent & Substitute Parts

Part Overview

The DCMM-37S is a 37-position D-Sub receptacle connector manufactured by ITT Cannon, LLC, designed for panel-mount applications with female socket contacts. This connector is actively produced and maintains an inventory of 1072 pieces in stock. The DCMM-37S serves as a standard interface component in applications requiring robust signal connectivity with solder cup termination.

Substitute parts become necessary when the primary part experiences supply constraints, when application requirements demand alternative mounting configurations, or when compliance specifications differ between design phases and production implementation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DCMM-37S is determined by strict alignment of the following core parameters:

Critical Matching Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 37
• Number of rows: 2
• Shell size and layout: 4 (DC, C)
• Termination type: Solder Cup
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold
• Flange feature: Housing/Shell (Unthreaded)
• Material flammability rating: UL94 V-0

The substitute part 5-747917-2 (TE Connectivity AMP Connectors, AMPLIMITE HD-20 series) satisfies all critical matching parameters. Variations in mounting type (panel mount versus free hanging), current rating, voltage rating, contact finish thickness, dielectric material composition, operating temperature maximum, and RoHS compliance status do not disqualify substitution when the core electrical and mechanical interface parameters align.

Engineering Selection Recommendations

DCMM-37S Selection Criteria:

• Applications requiring panel-mount configuration with fixed installation geometry
• Systems operating at temperatures exceeding 105°C, up to 150°C maximum
• Designs requiring current capacity of 7.5A per contact
• Applications where RoHS non-compliance is acceptable or required by legacy specifications
• Systems utilizing PCT dielectric material specifications

5-747917-2 Selection Criteria:

• Applications permitting free-hanging or in-line connector orientation
• Systems operating within -55°C to 105°C temperature range
• Designs where 3A current rating per contact satisfies electrical requirements
• New designs or production phases requiring ROHS3 compliance
• Applications where 250V voltage rating specification is required
• Systems utilizing PBT glass-filled dielectric material

Both parts maintain active product status and UL94 V-0 flammability certification. The selection between DCMM-37S and 5-747917-2 depends on specific application requirements regarding mounting method, thermal environment, current capacity, and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the 5-747917-2 directly replace the DCMM-37S in a panel-mount application?

A: The 5-747917-2 is configured for free-hanging (in-line) mounting, not panel mount. Physical installation geometry differs. Mechanical adaptation may be required depending on the application's mounting infrastructure.

Q: What is the significance of the current rating difference (7.5A versus 3A)?

A: The DCMM-37S supports 7.5A per contact, while the 5-747917-2 supports 3A per contact. Applications requiring current transmission exceeding 3A per contact cannot use the 5-747917-2 as a direct substitute without circuit redesign.

Q: Does the operating temperature range difference affect substitution?

A: The DCMM-37S operates to 150°C maximum; the 5-747917-2 operates to 105°C maximum. Applications requiring sustained operation above 105°C must use the DCMM-37S. The 5-747917-2 is unsuitable for high-temperature environments exceeding 105°C.

Q: What is the impact of RoHS compliance status on part selection?

A: The DCMM-37S is RoHS non-compliant; the 5-747917-2 is ROHS3 compliant. New product designs and production phases subject to RoHS regulations must use the 5-747917-2. Legacy systems or applications exempt from RoHS requirements may use either part.

Q: Are the contact finish thicknesses interchangeable?

A: Contact finish thickness differs: DCMM-37S has 50.0µin (1.27µm) gold plating; 5-747917-2 has 8.00µin (0.203µm) gold plating. Both provide gold contact finish for signal integrity. The thicker plating on DCMM-37S may provide extended contact life in high-cycle mating applications.

Q: What dielectric material differences exist between these parts?

A: DCMM-37S uses PCT (Polycyclohexylenedimethylene Terephthalate); 5-747917-2 uses PBT glass-filled (Polybutylene Terephthalate). Both materials meet UL94 V-0 flammability requirements. Material selection affects mechanical properties and thermal performance within their respective operating ranges.

Q: Can packaging format (Bulk versus Tray) affect substitution decisions?

A: Packaging format does not affect electrical or mechanical compatibility. DCMM-37S ships in Bulk packaging; 5-747917-2 ships in Tray packaging. Packaging selection depends on inventory management, handling procedures, and supply chain requirements, not connector functionality.
