DX20M-68S Equivalent & Substitute Parts

Part Overview

The DX20M-68S is a 68-position miniature high-density (HD) receptacle connector manufactured by Hirose Electric Co Ltd, designed for panel mount, through-hole solder termination applications. This connector features an outer shroud contact design with gold-plated contacts and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing system maintenance, repair, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DX20M-68S is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 68 positions (non-negotiable)
• Row Configuration: 2 rows (non-negotiable)
• Connector Type: Receptacle (non-negotiable)
• Mounting Configuration: Panel Mount, Through Hole (non-negotiable)
• Termination Method: Solder (non-negotiable)
• Connector Classification: Miniature High Density (HD) (non-negotiable)
• Contact Finish: Gold (non-negotiable)
• Connector Style: Outer Shroud Contacts (non-negotiable)
• Flange Feature: Housing/Shell (M2.6) (non-negotiable)

The substitute part DX20M-68S(50) maintains identical electrical and mechanical specifications across all critical parameters, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The DX20M-68S(50) serves as the direct functional equivalent to the obsolete DX20M-68S. Selection between these parts should be based on the following criteria:

Product Status: The DX20M-68S(50) maintains active product status with Hirose Electric Co Ltd, ensuring continued availability and support. The original DX20M-68S is classified as obsolete and subject to supply discontinuation.

Regulatory Compliance: The DX20M-68S(50) is RoHS Compliant, whereas the DX20M-68S is RoHS non-compliant. For applications requiring RoHS compliance, the DX20M-68S(50) is the appropriate selection.

Packaging Consideration: The DX20M-68S(50) is supplied in tray packaging, which may differ from the original bulk packaging format. Procurement and assembly processes should account for this packaging difference.

Electrical and Mechanical Equivalence: Both parts are electrically and mechanically identical across all functional parameters, including connector position count, row configuration, mounting type, termination method, contact finish, and flange specifications.

Frequently Asked Questions (FAQ)

Q: Are the DX20M-68S and DX20M-68S(50) electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications, including 68-position configuration, 2-row layout, gold contact finish, and solder termination. They are functionally equivalent for circuit applications.

Q: What is the significance of the "(50)" designation in DX20M-68S(50)?

A: The "(50)" designation indicates the packaging format. DX20M-68S(50) is supplied in tray packaging containing 50 units per tray, whereas the original DX20M-68S uses bulk packaging.

Q: Can I use DX20M-68S(50) as a direct replacement for DX20M-68S in existing designs?

A: Yes, provided that the application does not have specific packaging requirements. The connector itself is mechanically and electrically identical. Verify that tray packaging is compatible with your assembly and procurement workflow.

Q: Why is the DX20M-68S classified as obsolete?

A: Obsolescence is determined by the manufacturer based on market demand and product lifecycle decisions. The DX20M-68S(50) is the active equivalent and is the recommended selection for new designs and ongoing procurement.

Q: Does RoHS compliance status affect connector performance?

A: RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs) in the connector construction. For applications subject to RoHS regulations or customer requirements, the DX20M-68S(50) is the compliant option.

Q: Are there any mechanical differences between these connectors?

A: No. Both connectors share identical mechanical specifications, including panel mount configuration, through-hole solder termination, M2.6 housing/shell flange, and outer shroud contact design.

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

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
