3M 8237-6003 D-Sub 37-Position Panel Mount IDC Connector - Equivalent & Substitute Parts

Part Overview

The 3M 8237-6003 is a 37-position D-Sub plug connector with male pins, designed for panel mount applications using insulation displacement contact (IDC) termination with ribbon cable. This connector is classified as active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when design requirements permit variations in mounting configuration, current rating, or manufacturer while maintaining core electrical and mechanical compatibility within the D-Sub 37-position connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3M 8237-6003 are qualified based on the following core parameters that determine functional interchangeability:

Critical Parameters (Must Match):

• Connector style: D-Sub
• Connector type: Plug with male pins
• Number of positions: 37
• Shell size and layout: 4 (DC, C)
• Termination method: IDC, Ribbon Cable
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Mounting type: Panel mount (main part) may be substituted with free hanging (in-line) configurations when application design permits
• Current rating: 1A (main part) may be substituted with higher ratings (1.25A, 2A) as these provide equal or greater capacity
• Contact finish: Gold or unspecified finishes are acceptable substitutes
• Shell material finish: Steel with tin plate or steel without specified finish are acceptable
• Contact material: Copper alloy or phosphor bronze are acceptable
• Manufacturer: 3M, HARTING, or TE Connectivity AMP Connectors

Parameter Comparison

Engineering Selection Recommendations

Panel Mount Configuration (Direct Substitutes): HARTING 09664286700 and HARTING 09664287700 maintain the panel mount configuration of the 3M 8237-6003. Both parts are ROHS3 compliant, active status, and rated for 2A current capacity, which exceeds the 1A requirement of the main part. These substitutes are suitable for applications where panel mount geometry is required and higher current capacity is acceptable.

Free Hanging (In-Line) Configuration (Functional Substitutes): TE Connectivity AMPLIMITE HDF-20 series parts (1658608-1, 1658613-1, 1658615-1) provide functional equivalence with free hanging (in-line) mounting configuration. These parts are rated for 1.25A current capacity and operate across the same temperature range (-55°C to 105°C) as the main part. All three TE parts maintain RoHS compliance and MSL 1 rating. Selection among these three TE variants depends on specific flange feature and shell material requirements for the application.

Compliance Considerations: All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 moisture sensitivity level. HARTING parts are ROHS3 compliant. TE parts carry RoHS compliance designation. All parts are classified as active product status.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09664286700 or 09664287700 be used as direct replacements for 3M 8237-6003? A: Yes, both HARTING parts are direct substitutes for panel mount applications. They maintain the same 37-position D-Sub configuration, shell size 4 (DC, C), IDC ribbon cable termination, and UL94 V-0 flammability rating. The HARTING parts are rated for 2A current, which exceeds the 1A requirement of the 3M part.

Q: What is the primary difference between the 3M 8237-6003 and the TE Connectivity AMPLIMITE HDF-20 series parts? A: The primary difference is mounting configuration. The 3M part is panel mount, while the TE parts (1658608-1, 1658613-1, 1658615-1) are free hanging (in-line). All other core parameters—37 positions, shell size 4 (DC, C), IDC termination, and operating temperature range—are identical. Selection depends on whether the application requires panel mount or in-line mounting geometry.

Q: Are there differences among the three TE Connectivity substitute parts (1658608-1, 1658613-1, 1658615-1)? A: The three TE parts differ in flange feature configuration. Part 1658608-1 features housing/shell with 4-40 threading. Part 1658613-1 features unthreaded housing/shell. Part 1658615-1 also features unthreaded housing/shell. All three maintain identical electrical specifications (1.25A current rating, -55°C to 105°C operating temperature) and are AMPLIMITE HDF-20 series connectors.

Q: Can I use a substitute part with higher current rating than the 3M 8237-6003? A: Yes. The HARTING parts (09664286700, 09664287700) are rated for 2A, and the TE parts are rated for 1.25A. Higher current ratings provide equal or greater capacity and are acceptable substitutes when all other parameters match the application requirements.

Q: What packaging differences exist among these parts? A: The 3M 8237-6003 is supplied in tray packaging. All HARTING and TE substitute parts are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Are all substitute parts ROHS compliant? A: Yes. The 3M main part and HARTING substitutes are ROHS3 compliant. The TE Connectivity parts carry RoHS compliance designation. All parts meet regulatory compliance requirements.
