3M 10236-55H4VC D-Sub 36-Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The 3M 10236-55H4VC is a 36-position Mini D Ribbon (MDR) receptacle connector designed for panel mount, through-hole applications with right-angle solder termination. This connector features an outer shroud contact design with gold-plated contacts and board lock functionality. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10236-55H4VC is determined by the following critical parameters that must remain consistent:

• Connector Series & Type: Must remain 3M 102 Mini D Ribbon (MDR) series, 36-position receptacle
• Electrical Configuration: 36 positions in 2-row arrangement
• Mounting Interface: Panel mount, through-hole compatibility
• Contact System: Outer shroud contacts with gold plating (30.0µin minimum)
• Shielding: Shielded design requirement
• Mechanical Compatibility: Housing/shell fastening system

The primary substitute, 3M 10236-R21TS, maintains all critical electrical and mechanical parameters while offering an active product status. The key difference is the termination method transition from solder to press-fit, which represents a modernization of the connector interface while preserving form factor and functional compatibility within the 102 series platform.

Engineering Selection Recommendations

The 3M 10236-R21TS is the manufacturer-recommended substitute for the obsolete 10236-55H4VC. Selection of this substitute is supported by:

• Product Status: The substitute maintains active product status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The 10236-R21TS is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements
• Electrical Equivalence: Both parts maintain identical 36-position configuration, 2-row arrangement, gold contact finish (30.0µin), and shielded design
• Mechanical Compatibility: Both connectors use the same 102 series platform with panel mount, through-hole interface
• Termination Transition: The shift from solder to press-fit termination represents a standard modernization path within the 102 series, offering improved assembly reliability and reduced thermal stress on PCB substrates

Frequently Asked Questions (FAQ)

Q: Can the 10236-R21TS directly replace the 10236-55H4VC in existing designs?

A: The 10236-R21TS maintains electrical and mechanical compatibility as a 36-position, 2-row receptacle connector within the 102 series. The primary design consideration is the termination method change from solder to press-fit, which requires PCB layout modifications to accommodate press-fit contact holes rather than solder pads.

Q: What is the difference between the flange features (4-40 vs. M2.6)?

A: The flange feature specifies the fastening system for panel mounting. The 10236-55H4VC uses 4-40 UNC threaded holes, while the 10236-R21TS uses M2.6 metric threads. Panel cutout and mounting hardware must be selected accordingly for each connector variant.

Q: Are the contact finishes equivalent between these parts?

A: Both connectors feature gold-plated contacts with 30.0µin (0.76µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: Why is the 10236-55H4VC listed as obsolete?

A: The 10236-55H4VC has been superseded by the 10236-R21TS within the 3M product portfolio. The substitute offers active product status, improved regulatory compliance (ROHS3), and press-fit termination technology.

Q: Does the substitute maintain the board lock feature?

A: The 10236-R21TS is specified with shielded design and outer shroud contacts. The board lock feature is not listed for the substitute; design verification is required if board lock functionality is a critical system requirement.

Q: What are the packaging differences?

A: The 10236-55H4VC packaging is not specified in available data. The 10236-R21TS is supplied in tray packaging, which is standard for press-fit connector distribution.
