Key Parameters

Substitute Part Grouping Explanation

Substitution of the DCMM-37S-X is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle, female sockets
• Position count: 37 positions
• Row configuration: 2 rows
• Shell size and layout: 4 (DC, C)
• Mounting method: Through hole capability
• Termination method: Solder
• Contact form: Machined
• Shell material and finish: Steel with yellow chromate plated zinc
• Contact finish: Gold plating at 50.0µin (1.27µm)

The substitute part M24308/23-4Z, manufactured by Cinch Connectivity Solutions, meets these core mechanical and electrical compatibility criteria. Both parts conform to the D-Sub connector standard and share identical position, row, and shell size specifications, enabling direct functional substitution in panel mount, through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DCMM-37S-X and M24308/23-4Z are active products with RoHS non-compliant status. Selection between these parts should be based on application-specific requirements:

The DCMM-37S-X supports a higher current rating of 7.5A and operates across a wider temperature range (-55°C to 150°C), making it suitable for applications requiring extended thermal performance and higher current capacity.

The M24308/23-4Z, conforming to MIL-C-24308 military specifications, operates at 5A current rating with a temperature range of -65°C to 125°C. This part is appropriate for applications where military-grade qualification and lower temperature extremes are required.

Both connectors maintain mechanical and electrical compatibility through identical shell size, position count, row configuration, and solder termination. The choice between contact materials (copper alloy versus phosphor bronze) and dielectric materials (PCT versus DAP glass-filled) should be determined by specific application environmental and performance requirements.

Frequently Asked Questions (FAQ)

Q: Can M24308/23-4Z directly replace DCMM-37S-X in existing designs?

A: Mechanical and electrical compatibility is established through identical shell size (4, DC, C), position count (37), row configuration (2), and solder termination. However, the M24308/23-4Z has a lower current rating (5A versus 7.5A) and narrower operating temperature range (-65°C to 125°C versus -55°C to 150°C). Substitution is valid only if the application does not exceed 5A current and operates within the -65°C to 125°C range.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical D-Sub shell size 4 (DC, C) configuration, 37-position layout in 2 rows, and through-hole mounting capability. Both feature unthreaded housing/shell flanges and machined contact forms, ensuring physical interchangeability in panel mount applications.

Q: How do the contact materials differ?

A: The DCMM-37S-X uses copper alloy contacts, while the M24308/23-4Z uses phosphor bronze contacts. Both are plated with gold at 50.0µin (1.27µm) thickness. Contact material selection should align with application corrosion resistance and mechanical durability requirements.

Q: Are there differences in dielectric materials?

A: Yes. The DCMM-37S-X uses polycyclohexylenedimethylene terephthalate (PCT), while the M24308/23-4Z uses diallyl phthalate (DAP) glass-filled material. Both are suitable for solder termination applications; selection depends on specific environmental exposure and thermal cycling requirements.

Q: What is the significance of the military specification designation?

A: The M24308/23-4Z conforms to MIL-C-24308 military connector specifications, indicating qualification for military and aerospace applications. The DCMM-37S-X does not carry this designation. Selection should reflect whether military-grade qualification is a requirement for the application.
