Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DCMM37SB is determined by the following critical parameters that must match or be compatible with the main part:

• Connector Type: Must be D-Sub receptacle with female sockets
• Position Count: Must be 37 positions
• Row Configuration: Must be 2 rows
• Shell Size: Must be size 4 (DC, C)
• Mounting Method: Must support panel mount, through-hole installation
• Termination Method: Must be solder-compatible
• Contact Finish: Gold plating required for signal integrity
• Operating Temperature: Must support -55°C minimum; upper limit may vary by application

The three substitute parts listed below meet these core electrical and mechanical requirements. Variations in shell finish material, RoHS compliance status, and current rating specifications are noted in the parameter comparison table and must be evaluated against specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

DCMM37SB (ITT Cannon, LLC) — Primary specification. RoHS compliant. Supports full operating temperature range of -55°C to 150°C. Current rating of 7.5A. UL94 V-0 flammability rating. Recommended for applications requiring RoHS compliance and extended temperature performance.

M24308/23-10F (Amphenol Interconnect India) — Military specification MIL-C-24308 compliance. Matches current rating (7.5A) and temperature range (-55°C to 125°C). RoHS non-compliant. Suitable for military or defense applications where MIL-DTL specifications are required. Highest inventory availability (665 units).

M24308/23-4F (TE Connectivity Aerospace, Defense and Marine) — Military specification MIL-DTL-24308 compliance. Current rating reduced to 5A; operating temperature limited to -55°C to 125°C. RoHS non-compliant. Largest inventory (1314 units). Suitable for military applications where MIL-DTL-24308 specification is mandated, provided 5A current rating meets application requirements.

628-037-220-041 (Mercury United Electronics, Inc.) — Limited technical specification data provided. Metal shell construction. Highest inventory (991 units). Substitution feasibility requires verification of unlisted parameters against application requirements.

Frequently Asked Questions (FAQ)

Q: Can M24308/23-4F substitute for DCMM37SB in all applications?

A: M24308/23-4F meets core mechanical and electrical compatibility requirements (37 positions, 2 rows, size 4 shell, solder termination, gold contact finish). However, the current rating is reduced to 5A versus 7.5A on the DCMM37SB. Applications requiring 7.5A current capacity must use DCMM37SB or M24308/23-10F. Additionally, M24308/23-4F is RoHS non-compliant and operates to 125°C maximum versus 150°C on the DCMM37SB.

Q: What is the difference between the military-specification parts and the commercial DCMM37SB?

A: M24308/23-10F and M24308/23-4F are manufactured to military specifications MIL-C-24308 and MIL-DTL-24308 respectively, which impose stricter manufacturing, testing, and quality control requirements. The DCMM37SB is a commercial-grade connector. Both meet the core 37-position, 2-row, size 4 D-Sub receptacle requirements. Military parts are RoHS non-compliant due to cadmium plating; the DCMM37SB uses chromate plating and is RoHS compliant.

Q: Is the 628-037-220-041 from Mercury a direct replacement?

A: The 628-037-220-041 meets the fundamental connector type, position count, row configuration, and shell size requirements. However, critical parameters including current rating, contact finish thickness, operating temperature range, and material specifications are not provided in available documentation. Detailed specification verification is necessary before confirming substitution eligibility.

Q: What mounting differences exist between these parts?

A: DCMM37SB and M24308/23-10F are specified for panel mount, through-hole installation. M24308/23-4F is specified for through-hole mounting without explicit panel mount designation. The 628-037-220-041 is specified as vertical mount. Mounting configuration must be verified against PCB layout and mechanical assembly requirements.

Q: Which substitute part has the best inventory availability?

A: M24308/23-4F has the highest inventory with 1314 units in stock, followed by 628-037-220-041 with 991 units and M24308/23-10F with 665 units. The primary DCMM37SB has 787 units available.
