MDSMT2ARATR Equivalent & Substitute Parts

Part Overview

The MDSMT2ARATR is a 2.5mm mono phone jack connector manufactured by Switchcraft Inc., designed for surface mount, right-angle solder applications. This connector features a single internal switch, unshielded design, and board guide for secure mounting. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDSMT2ARATR is determined by strict equivalence across the following parameters:

• Connector type (Phone Jack)
• Mating diameter (2.50mm)
• Signal configuration (Mono)
• Contact count (2 Conductors, 3 Contacts)
• Mounting type (Surface Mount, Right Angle)
• Termination method (Solder)
• Internal switch configuration (Single Switch)
• Current rating (3 A minimum)
• Operating temperature range (-25°C to 85°C minimum)
• Contact material and plating (Silver-plated Copper Alloy)
• Housing material (Thermoplastic)
• Shielding type (Unshielded)

The MDSMT2ARATRX meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MDSMT2ARATRX is the direct equivalent substitute for the MDSMT2ARATR. Both parts are manufactured by Switchcraft Inc. and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the MDSMT2ARATR is obsolete, while the MDSMT2ARATRX is active and currently in production.

The MDSMT2ARATRX offers an additional compliance advantage: it is ROHS3 compliant, whereas the MDSMT2ARATR is RoHS non-compliant. This compliance improvement makes the MDSMT2ARATRX suitable for applications subject to RoHS regulations.

Both parts maintain identical packaging (Tape & Reel), current rating (3 A), operating temperature range (-25°C to 85°C), and contact configuration. Footprint and PCB layout compatibility is assured due to identical mounting type and dimensions.

Frequently Asked Questions (FAQ)
