DX20M-20S Equivalent & Substitute Parts

Part Overview

The DX20M-20S is a 20-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 equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service requirements.

Key Parameters

Substitute Part Grouping Explanation

The DX20M-20S(50) qualifies as a direct substitute based on the following critical parameters:

• Identical connector type (Receptacle)
• Identical position count (20 positions, 2 rows)
• Identical mounting configuration (Panel Mount, Through Hole)
• Identical termination method (Solder)
• Identical connector style (Outer Shroud Contacts)
• Identical miniature HD classification
• Identical flange feature (Housing/Shell M2.6)
• Identical contact finish (Gold)
• Same manufacturer (Hirose Electric Co Ltd)
• Same series (DXM)

The primary distinction is product status and packaging configuration. The DX20M-20S(50) is an active product supplied in tray packaging, whereas the original DX20M-20S is obsolete with unspecified packaging.

Parameter Comparison

Engineering Selection Recommendations

The DX20M-20S(50) is the direct substitute for the obsolete DX20M-20S. All electrical and mechanical parameters are identical, ensuring form, fit, and function compatibility. The substitute part offers the additional advantage of ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and regulatory classifications (REACH Unaffected, ECCN EAR99).

The DX20M-20S(50) is supplied in tray packaging and maintains active product status with current inventory availability, making it the appropriate selection for new designs and component replenishment.

Frequently Asked Questions (FAQ)

Q: Are the DX20M-20S and DX20M-20S(50) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including panel mount configuration, through-hole solder termination, 20-position layout with 2-row arrangement, miniature HD form factor, and M2.6 housing/shell flange feature.

Q: What is the difference between DX20M-20S and DX20M-20S(50)?

A: The primary differences are product status (obsolete versus active), packaging format (unspecified versus tray), and RoHS compliance (non-compliant versus ROHS3 compliant). All functional and mechanical parameters are identical.

Q: Can I use DX20M-20S(50) in place of DX20M-20S in existing designs?

A: Yes. The DX20M-20S(50) is a direct substitute with identical electrical and mechanical characteristics. The improved RoHS3 compliance of the substitute part may provide additional regulatory benefits.

Q: What does the "(50)" designation indicate in DX20M-20S(50)?

A: The "(50)" designation indicates the packaging quantity or configuration. The DX20M-20S(50) is supplied in tray packaging format.

Q: Are there any compliance differences between these parts?

A: The DX20M-20S(50) is ROHS3 compliant, while the original DX20M-20S is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications.
