DCM37P500N D-Sub Connector Equivalent & Substitute Parts

Part Overview

The DCM37P500N is a 37-position D-Sub plug connector manufactured by Amphenol ICC (FCI) with right-angle through-hole solder termination. This connector is classified as obsolete, which necessitates identification of functionally equivalent active alternatives for ongoing design support and procurement.

The DCM37P500N serves as a signal connector in applications requiring 37-position D-Sub connectivity with the specified electrical and mechanical characteristics. Due to its obsolete status, equivalent active parts must be evaluated to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DCM37P500N is based on strict equivalence across the following critical parameters:

Electrical Compatibility:

• 37-position configuration with 2-row layout
• Shell size 4 (DC, C) D-Sub format
• 7.5A per contact current rating
• 300V voltage rating
• Gold-plated brass contacts
• Thermoplastic dielectric material

Mechanical Compatibility:

• Right-angle through-hole mounting orientation
• Solder termination method
• Steel shell with yellow cadmium plating
• Unthreaded housing/shell flange feature

Environmental & Compliance:

• UL94 V-0 flammability rating
• MSL 1 (Unlimited) moisture sensitivity
• RoHS non-compliant status

The substitute part DCM37P500 maintains all critical electrical and mechanical parameters. The primary distinction is product status: DCM37P500N is obsolete, while DCM37P500 is active. Both parts share the same base product number (DCM37) and belong to the DM HE series of D-Sub connectors.

Parameter Comparison

Engineering Selection Recommendations

DCM37P500 is the direct active equivalent for DCM37P500N. Both parts are manufactured by Amphenol ICC (FCI) and maintain identical electrical and mechanical specifications across all critical parameters including connector configuration, pin count, current and voltage ratings, material composition, and flammability certification.

The primary consideration for selection is the operating temperature range. DCM37P500N supports -55°C to 155°C, while DCM37P500 supports -55°C to 125°C. Applications requiring operation above 125°C must retain DCM37P500N or identify alternative solutions. For applications operating within the -55°C to 125°C range, DCM37P500 provides equivalent functionality with the advantage of active product status and current manufacturing availability.

Both parts maintain RoHS non-compliant status and identical compliance certifications. Packaging differs, with DCM37P500 supplied in Tray format. Design compatibility is assured for direct substitution within the specified temperature operating window.

Frequently Asked Questions (FAQ)

Q: Can DCM37P500 directly replace DCM37P500N in existing designs?

A: Yes, for applications operating within -55°C to 125°C. Both connectors are electrically and mechanically identical across all critical parameters: 37-position D-Sub configuration, 7.5A per contact current rating, 300V voltage rating, solder termination, and identical material specifications. If your application requires operation above 125°C, DCM37P500N must be retained.

Q: What is the difference between the DM HE508 and DM HE501 series designations?

A: Both series are D-Sub connector lines from Amphenol ICC (FCI). The series designation reflects internal product line organization. The functional and electrical specifications are equivalent for these specific part numbers.

Q: Why is DCM37P500N listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. DCM37P500 is the active equivalent maintained in current manufacturing and inventory.

Q: Are there packaging differences between these parts?

A: DCM37P500 is specified as supplied in Tray packaging. Original packaging specification for DCM37P500N is not provided in the technical data. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts carry UL94 V-0 flammability rating, MSL 1 (Unlimited) moisture sensitivity level, and RoHS non-compliant status. Compliance certifications are identical.

Q: What is the backset spacing for these connectors?

A: Both DCM37P500N and DCM37P500 have a backset spacing of 0.406" (10.30mm).

Q: Can I use these connectors in high-temperature applications above 125°C?

A: DCM37P500 is rated to 125°C maximum. If your application requires operation above 125°C, DCM37P500N with its 155°C rating must be used. Verify temperature requirements against your application specifications before final part selection.
