3M 10220-55H3VC D-Sub Receptacle Connector: Equivalent & Substitute Parts

Part Overview

The 3M 10220-55H3VC is a 20-position Mini D Ribbon (MDR) receptacle connector designed for panel mount, through-hole, right-angle solder termination applications. This connector features an outer shroud contact design with board lock and shielding capabilities. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the 10220-55H3VC are identified based on strict electrical and mechanical parameter alignment:

Primary Substitution Criteria:

• Connector type: Receptacle
• Position count: 20 positions
• Row configuration: 2 rows
• Mounting: Panel mount, through-hole, right-angle orientation
• Termination: Solder
• Connector style: Outer shroud contacts
• Features: Board lock capability

Identified Substitutes:

1. 3M 10220-55H3PC — Direct manufacturer equivalent with identical electrical and mechanical specifications. Differs only in packaging (bulk vs. original) and product status (active vs. obsolete). RoHS compliant.

2. TE Connectivity 5178240-2 — Functionally equivalent receptacle connector from CHAMP .050 II series. Meets all core electrical and mechanical requirements. Flange feature differs (M2.6 vs. 4-40) but maintains compatibility for panel mount applications. RoHS3 compliant with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 3M 10220-55H3PC is the primary substitute for the obsolete 10220-55H3VC. Both parts share identical electrical and mechanical specifications, including contact finish thickness and shielding features. The 10220-55H3PC is active in production with RoHS compliance, making it suitable for new designs and legacy system support.

For Alternative Selection: The TE Connectivity 5178240-2 provides a functionally equivalent option with active product status and significantly higher inventory availability (8106 units). This part meets all core connector requirements and is ROHS3 compliant. The contact finish thickness is thinner (11.8µin vs. 30.0µin), and shielding is limited to board lock only. This alternative is appropriate when supply constraints exist or when the reduced contact finish thickness is acceptable for the application.

Compliance Considerations: The original 10220-55H3VC is RoHS non-compliant. Both substitute parts offer RoHS compliance, with the 10220-55H3PC matching the original specification more closely and the 5178240-2 providing ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can the 3M 10220-55H3PC directly replace the 10220-55H3VC without design modification? A: Yes. The 10220-55H3PC is electrically and mechanically identical to the 10220-55H3VC. Packaging differs (bulk vs. original), but connector specifications are equivalent. No PCB or assembly changes are required.

Q: What are the key differences between the 3M 10220-55H3PC and TE Connectivity 5178240-2? A: Both are 20-position, 2-row receptacle connectors with panel mount, right-angle solder termination. The primary differences are: (1) flange feature specification (4-40 vs. M2.6), (2) contact finish thickness (30.0µin vs. 11.8µin), and (3) shielding features (shielded with board lock vs. board lock only). The TE part offers higher inventory availability.

Q: Is the TE Connectivity 5178240-2 suitable for applications requiring full shielding? A: The 5178240-2 includes board lock but does not specify shielding equivalent to the 3M parts. If electromagnetic shielding is a critical requirement, the 3M 10220-55H3PC is the preferred substitute.

Q: What is the impact of different contact finish thicknesses on connector performance? A: Contact finish thickness affects durability and wear resistance. The 3M parts (30.0µin) provide thicker gold plating than the TE part (11.8µin). For high-cycle mating applications or extended service life requirements, the thicker finish is preferable.

Q: Are there packaging considerations when selecting between these substitutes? A: The 3M 10220-55H3PC is supplied in bulk packaging, while the original 10220-55H3VC and TE 5178240-2 use different packaging formats. Verify packaging compatibility with your procurement and assembly processes.
