MD-30S Equivalent & Substitute Parts

Part Overview

The MD-30S is a 3-position circular connector receptacle manufactured by CUI Devices, featuring female sockets with solder termination and right-angle through-hole mounting. This Mini DIN connector is designed for applications requiring push-pull fastening with keyed orientation and board lock functionality. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MD-30S is determined by strict alignment across the following critical parameters:

• Connector type and gender (Receptacle, Female Sockets)
• Position count (3 positions)
• Shell size classification (Mini DIN)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Keyed orientation requirement
• Current and voltage ratings (minimum 1A/2A at 100VAC/12VDC)
• Operating temperature range (-40°C ~ 85°C)

The 2MJ-0001A110 meets all core electrical and mechanical compatibility criteria for direct substitution in applications previously specified for the MD-30S.

Parameter Comparison

Engineering Selection Recommendations

The 2MJ-0001A110 provides functional equivalence to the obsolete MD-30S across all critical mechanical and electrical parameters. The substitute part maintains identical connector geometry, contact ratings, and thermal operating range.

Compliance consideration: The MD-30S carries RoHS Compliant certification, while the 2MJ-0001A110 is RoHS non-compliant. Selection between these parts must account for regulatory requirements in the target application and end-market jurisdiction. The 2MJ-0001A110 is listed as discontinued at DiGi Electronics, requiring verification of current availability through alternative distribution channels.

The voltage rating differential (12VDC for MD-30S versus 24VDC for 2MJ-0001A110) indicates the substitute part is rated for higher voltage operation, making it suitable for applications within the original MD-30S specification envelope.

Frequently Asked Questions (FAQ)

Q: Can the 2MJ-0001A110 be used as a direct replacement for the MD-30S?

A: Yes, the 2MJ-0001A110 meets all core mechanical and electrical compatibility requirements. Both connectors share identical position count, shell size, mounting configuration, termination method, and current/voltage ratings within the specified operating range.

Q: What is the primary difference between these two parts?

A: The primary differences are manufacturer origin and regulatory compliance status. The MD-30S is RoHS Compliant, while the 2MJ-0001A110 is RoHS non-compliant. The 2MJ-0001A110 also carries a higher voltage rating (24VDC versus 12VDC), which does not restrict its use in lower-voltage applications.

Q: Are there packaging differences between the MD-30S and 2MJ-0001A110?

A: The MD-30S is supplied in standard packaging, while the 2MJ-0001A110 is packaged in bulk. Both are suitable for through-hole solder assembly processes.

Q: What should be verified before implementing the 2MJ-0001A110 as a substitute?

A: Verify current availability through authorized distributors, confirm RoHS compliance requirements for your application and target market, and validate that the substitute part's higher voltage rating does not introduce unintended design changes.

Q: Is the operating temperature range identical between both parts?

A: Yes, both the MD-30S and 2MJ-0001A110 operate across the identical temperature range of -40°C to 85°C.
