DX20M-26S Equivalent & Substitute Parts

Part Overview

The DX20M-26S is a 26-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 active alternatives is essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the DX20M-26S is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 26 positions in 2 rows
• Physical Form Factor: Miniature high-density (HD) D-Sub connector with outer shroud contacts
• Mounting & Termination: Panel mount through-hole solder termination
• Mechanical Interface: Housing/shell with M2.6 flange feature
• Electrical Properties: Gold contact finish with MSL 1 rating

The substitute part DX20M-26S(50) maintains identical electrical and mechanical specifications while offering improved product status and compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The DX20M-26S(50) is the direct functional equivalent of the DX20M-26S, offering identical electrical and mechanical specifications with the following advantages:

Product Status: The substitute part maintains active product status, ensuring long-term availability and manufacturer support compared to the obsolete main part.

Compliance: DX20M-26S(50) achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

Packaging: The substitute is supplied in tray packaging, which may offer improved handling and storage characteristics compared to bulk packaging.

For applications requiring the 26-position miniature HD D-Sub receptacle connector with panel mount through-hole solder termination, DX20M-26S(50) provides full functional compatibility with enhanced compliance and availability.

Frequently Asked Questions (FAQ)

Q: Are DX20M-26S and DX20M-26S(50) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 26-position configuration, 2-row layout, miniature HD form factor, M2.6 housing/shell flange, and panel mount through-hole mounting interface.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), and packaging format (bulk vs. tray). Electrical and mechanical performance are equivalent.

Q: Can DX20M-26S(50) be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical contact finish (gold), termination method (solder), connector style (outer shroud contacts), and MSL rating (1 - Unlimited), enabling direct substitution in PCB designs and panel mount applications.

Q: Does packaging format affect connector performance?

A: No. Tray packaging in DX20M-26S(50) provides the same connector performance as bulk packaging in the original part. Packaging differences relate only to handling, storage, and supply chain logistics.

Q: Are there compliance considerations for design transitions?

A: Yes. If RoHS3 compliance is required for new designs or procurement, DX20M-26S(50) is the appropriate selection. Both parts maintain REACH Unaffected status and identical HTSUS classification (8536.69.4040).
