Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDMH37SS is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: D-Type, Micro-D
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 37
• Number of Rows: 2
• Mounting Type: Panel Mount
• Shell Size, Connector Layout: 0.050 Pitch x 0.043 Row to Row
• Contact Type: Signal
• Flange Feature: Mating Side, Female Screwlock (2-56)
• Termination: Solder Cup
• Current Rating: 3A
• Features: Shielded
• Contact Material: Copper Alloy
• Operating Temperature Range: -55°C ~ 125°C

The substitute part MDM-37SSP meets all mandatory matching parameters. Variations in shell material finish, dielectric material composition, and packaging format do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both MDMH37SS and MDM-37SSP are active products manufactured by ITT Cannon, LLC, and are functionally equivalent for applications requiring 37-position Micro-D receptacle connectors with panel mount configuration and solder cup termination.

Selection Criteria:

The MDMH37SS features a steel shell with tin-lead plating and diallyl phthalate dielectric material with a Moisture Sensitivity Level of 1 (Unlimited). This configuration is suitable for general industrial and commercial applications without MSL-related storage constraints.

The MDM-37SSP features an aluminum shell with yellow chromate cadmium plating and liquid crystal polymer dielectric material. This variant is classified as RoHS non-compliant. Selection of MDM-37SSP is appropriate for applications where RoHS compliance is not a requirement and where aluminum shell construction is acceptable.

Both parts maintain identical electrical performance characteristics, including 3A current rating, shielded configuration, and -55°C to 125°C operating temperature range. Substitution between these parts is permissible based on material availability, packaging requirements, and regulatory compliance needs of the end application.

Frequently Asked Questions (FAQ)

Q: Are MDMH37SS and MDM-37SSP mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 37-position configuration, 0.050 pitch x 0.043 row-to-row spacing, panel mount design, and female screwlock flange feature (2-56). Physical mating and mounting are fully compatible.

Q: What is the difference in shell material between these two parts?

A: The MDMH37SS uses a steel shell with tin-lead plating. The MDM-37SSP uses an aluminum shell with yellow chromate cadmium plating. Both materials provide shielding functionality and support the specified 3A current rating. Material selection may depend on application-specific requirements for weight, corrosion resistance, or environmental exposure.

Q: Do these connectors have different electrical performance?

A: No. Both connectors maintain identical electrical specifications: 3A current rating, shielded configuration, copper alloy contacts with gold finish, and -55°C to 125°C operating temperature range. Electrical performance is equivalent.

Q: What is the significance of the different dielectric materials?

A: The MDMH37SS uses diallyl phthalate (DAP) glass-filled dielectric material. The MDM-37SSP uses liquid crystal polymer (LCP) dielectric material. Both materials are suitable for the specified operating temperature range and signal contact applications. Material selection reflects manufacturing process variations and does not affect functional compatibility.

Q: Is RoHS compliance a factor in selecting between these parts?

A: The MDMH37SS RoHS status is not specified in the provided data. The MDM-37SSP is explicitly RoHS non-compliant. If RoHS compliance is required for the end application, this factor must be evaluated during part selection.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: The MDMH37SS has MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. The MDM-37SSP has MSL listed as Not Applicable. MSL 1 classification provides maximum flexibility for inventory management and storage conditions.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, for applications where the specified electrical and mechanical parameters are the only design constraints. However, if the original design specifies material composition, RoHS compliance, or MSL requirements, these factors must be verified before substitution.

Q: What is the current inventory status for each part?

A: The MDMH37SS has 910 pieces in stock. The MDM-37SSP has 1188 pieces in stock. Both are listed as active products with new original inventory available.
