HARTING 09654237803 D-Sub Plug 37-Position Right Angle Solder Connector

Part Overview

The HARTING 09654237803 is a 37-position D-Sub plug connector with right-angle through-hole solder termination. This connector is designed for applications requiring robust signal transmission in industrial and commercial environments. The part is currently active in production with 718 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements necessitate alternative contact materials, flange configurations, or compliance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09654237803 is determined by the following critical parameters:

• Connector Type: Plug with male pins (37-position configuration)
• Mounting Configuration: Through-hole, right-angle orientation
• Termination Method: Solder attachment
• Shell Size and Layout: Size 4 (DC, C) D-Sub standard
• Number of Positions and Rows: 37 positions in 2-row configuration
• Operating Temperature Range: -55°C to 125°C minimum
• Material Flammability: UL94 V-0 compliance

The identified substitute parts from Amphenol ICC (FCI) maintain these core functional parameters. Variations in contact material finish, flange design, and RoHS compliance status are secondary considerations that do not affect mechanical or electrical interchangeability in standard D-Sub applications. The DCM37P500 and DCML37P500M are direct plug equivalents with identical connector type and orientation. The DCM37S300 is a receptacle variant and serves as a mating component rather than a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Direct Plug Substitutes (Functionally Equivalent)

The Amphenol ICC (FCI) DCM37P500 and DCML37P500M are functionally equivalent to the HARTING 09654237803 for applications requiring a 37-position D-Sub plug with right-angle solder termination. Both parts maintain identical connector geometry, pin configuration, and mounting orientation. The DCM37P500 is available in standard housing configuration, while the DCML37P500M includes M3 mounting brackets for panel-mount applications.

RoHS Compliance Consideration

The HARTING 09654237803 is ROHS3 compliant. The Amphenol substitute parts (DCM37P500 and DCML37P500M) are RoHS non-compliant due to yellow cadmium plating on the steel shell. Selection between these parts must account for end-product regulatory requirements. Applications subject to RoHS directives must retain the HARTING part or identify alternative suppliers offering RoHS-compliant 37-position D-Sub plugs.

Receptacle Variant (Mating Component)

The Amphenol DCM37S300 is a 37-position D-Sub receptacle with female sockets and vertical through-hole mounting. This part is not a direct substitute for the plug configuration but serves as the mating connector in cable and harness assemblies. The DCM37S300 is suitable for applications where a receptacle interface is required.

Current Rating

The Amphenol substitute parts are rated for 7.5A per contact, exceeding the HARTING part's 6.5A rating. This higher current capacity does not create compatibility issues and may provide additional design margin in power distribution applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol DCM37P500 directly replace the HARTING 09654237803 in existing designs?

A: Yes, the DCM37P500 is mechanically and electrically compatible. Both connectors share identical 37-position D-Sub geometry, right-angle solder termination, and -55°C to 125°C operating range. The primary difference is RoHS compliance status. If your application or end-product is not subject to RoHS regulations, the DCM37P500 is a direct substitute. If RoHS compliance is required, the HARTING part must be retained.

Q: What is the difference between DCM37P500 and DCML37P500M?

A: Both are 37-position D-Sub plugs with identical electrical and mechanical specifications. The DCML37P500M includes M3 mounting brackets integrated into the connector housing, enabling direct panel mounting. The DCM37P500 uses a standard unthreaded housing. Select DCML37P500M if panel-mount capability is required; otherwise, either part is suitable.

Q: Is the DCM37S300 a substitute for the HARTING 09654237803?

A: No. The DCM37S300 is a receptacle (female sockets) with vertical mounting, while the HARTING part is a plug (male pins) with right-angle mounting. These are complementary mating connectors, not substitutes. The DCM37S300 is used as the receiving end of a cable or harness assembly.

Q: What are the packaging differences among these parts?

A: The HARTING 09654237803 is supplied in bulk packaging. The Amphenol substitute parts (DCM37P500, DCML37P500M, and DCM37S300) are supplied in tray packaging. Tray packaging provides improved protection during storage and handling compared to bulk packaging.

Q: Are there any electrical performance differences between the HARTING and Amphenol parts?

A: Both maintain identical operating temperature range (-55°C to 125°C) and UL94 V-0 flammability rating. The Amphenol parts support higher current per contact (7.5A versus 6.5A), which is advantageous for power applications. Contact material differs (copper alloy versus brass/phosphor bronze), but this does not affect standard signal transmission applications.

Q: What should I consider when switching from HARTING to Amphenol parts?

A: Verify RoHS compliance requirements for your end-product. If RoHS compliance is mandatory, retain the HARTING part. If not required, the Amphenol parts offer equivalent performance with higher current capacity and greater inventory availability (809–1109 units in stock versus 718 units for HARTING).
