MDSMT2BRATR Equivalent & Substitute Parts

Part Overview

The MDSMT2BRATR is a 2.5mm stereo phone jack connector manufactured by Switchcraft Inc., designed for surface mount, right-angle applications with solder termination. This connector features a 3-conductor TRS (Tip-Ring-Sleeve) configuration and is rated for 3A current capacity. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDSMT2BRATR is determined by strict equivalence across the following critical parameters:

• Connector Type & Signal Configuration: Must be Phone Jack, Stereo (3 Conductor, TRS)
• Mating Diameter: Must be 2.50mm (0.094", 3/32", Sub Mini, Miniature)
• Mounting & Termination: Must be Surface Mount, Right Angle with Solder termination
• Electrical Ratings: Current rating of 3A minimum; operating temperature range -25°C ~ 85°C minimum
• Contact & Housing Materials: Silver plating on Copper Alloy contacts; Thermoplastic housing

The MDSMT2BRATRX qualifies as a direct substitute based on identical alignment across all these parameters. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The MDSMT2BRATRX is the direct substitute for the obsolete MDSMT2BRATR. Both parts share identical electrical and mechanical specifications, including connector type, mating diameter, signal configuration, mounting orientation, and current rating.

The MDSMT2BRATRX offers two significant advantages:

1. Product Status: Active production status ensures ongoing availability and supply chain reliability, eliminating obsolescence risk.
2. Regulatory Compliance: ROHS3 compliance versus non-compliance of the original part aligns with current environmental and regulatory requirements for new designs and production runs.

The packaging difference (Tape & Reel for MDSMT2BRATRX versus standard packaging for MDSMT2BRATR) does not affect functional compatibility and is a procurement consideration only.

Frequently Asked Questions (FAQ)

Q: Can MDSMT2BRATRX be used as a direct replacement for MDSMT2BRATR in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 2.5mm stereo phone jack, 3-conductor TRS configuration, surface mount right-angle orientation, solder termination, and 3A current rating. No circuit or layout modifications are required.

Q: What is the significance of the packaging difference between these parts?

A: MDSMT2BRATR uses standard packaging, while MDSMT2BRATRX is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact electrical or mechanical performance. Tape & Reel packaging is standard for high-volume surface mount production.

Q: Why is RoHS compliance status different between the two parts?

A: The MDSMT2BRATR is RoHS non-compliant, while MDSMT2BRATRX is ROHS3 compliant. For new designs or applications subject to RoHS regulations, MDSMT2BRATRX is the appropriate selection. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: Are there any temperature or current rating differences that would affect substitution?

A: No. Both parts operate across the identical temperature range (-25°C ~ 85°C) and are rated for 3A current. Substitution does not introduce any electrical performance limitations.

Q: What is the base product number relationship?

A: MDSMT2BRATRX references base product number MDSMT2, indicating it is part of the same product family. The MDSMT series designation confirms design and functional equivalence.
