D-Sub 20 Position Receptacle Connector D10220-55H3VC Equivalent & Substitute Parts

Part Overview

The D10220-55H3VC is a 20 position receptacle connector from 3M's 102 Mini D Ribbon (MDR) series, configured for panel mount through-hole right-angle solder termination. This connector features board lock and shielding with gold-plated contacts. The part is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D10220-55H3VC is determined by the following core parameters:

• Connector Type & Position Count: All substitutes must be 20 position receptacle connectors
• Mounting Configuration: Panel mount, through-hole, right-angle orientation required
• Termination Method: Solder termination only
• Connector Style: Outer shroud contacts with board lock feature
• Contact Material: Gold plating for electrical compatibility

The two identified substitutes meet these core electrical and mechanical requirements. The primary difference between substitutes lies in manufacturer series designation, flange specifications, and compliance certifications rather than functional connector characteristics.

Parameter Comparison

Engineering Selection Recommendations

10220-55H3PC (3M) is the primary substitute for D10220-55H3VC. Both connectors are from the same 3M 102 Mini D Ribbon series with identical electrical and mechanical specifications. The 10220-55H3PC maintains the same 20 position configuration, right-angle solder termination, board lock, shielding, and gold contact finish with matching thickness. The primary distinction is product status: 10220-55H3PC is active with RoHS compliance and defined moisture sensitivity rating, whereas D10220-55H3VC is obsolete. This substitute provides direct functional equivalence with improved compliance documentation.

5178240-2 (TE Connectivity) is a secondary substitute from the CHAMP .050 II series. It maintains all core functional requirements: 20 position receptacle, panel mount through-hole right-angle solder termination, outer shroud contacts, and board lock. The connector differs in flange specification (M2.6 versus 4-40) and contact finish thickness (11.8µin versus 30.0µin). The 5178240-2 is active with ROHS3 compliance. Selection of this substitute requires mechanical compatibility verification for the flange mounting interface and assessment of whether reduced contact finish thickness meets application requirements.

Frequently Asked Questions (FAQ)

Q: Can 10220-55H3PC directly replace D10220-55H3VC without design modification?

A: Yes. Both connectors are from the 3M 102 Mini D Ribbon series with identical position count, mounting configuration, termination method, and contact specifications. No design modification is required.

Q: What are the key differences between the 3M and TE Connectivity substitutes?

A: The primary differences are manufacturer series (102 MDR versus CHAMP .050 II), flange mounting specification (4-40 versus M2.6), and contact finish thickness (30.0µin versus 11.8µin). All three connectors maintain the same 20 position receptacle configuration and right-angle solder termination.

Q: Does the reduced contact finish thickness of 5178240-2 affect electrical performance?

A: Contact finish thickness is provided in the specification data. Selection of 5178240-2 requires assessment of whether 11.8µin gold plating meets the electrical and environmental requirements of the application.

Q: Are both substitutes RoHS compliant?

A: Yes. 10220-55H3PC is RoHS Compliant, and 5178240-2 is ROHS3 Compliant. Both meet current RoHS requirements.

Q: What is the inventory status of these substitutes?

A: 10220-55H3PC has 901 pieces in stock (Bulk packaging). 5178240-2 has 8106 pieces in stock (Box packaging). Availability should be confirmed with the supplier for production requirements.

Q: Can I use 5178240-2 if my design uses 4-40 mounting holes?

A: No. The 5178240-2 uses M2.6 flange specification, which is not compatible with 4-40 mounting holes. Mechanical compatibility must be verified before selection.
