MS2B-T Mini Shunt 2.0mm 2-Position Connector - Equivalent & Substitute Parts

Part Overview

The MS2B-T is a 2-position mini shunt connector manufactured by Adam Tech, featuring a 2.0mm pitch and tin contact finish. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement. The MS2B-T serves as a jumper connector for low-voltage signal routing and configuration applications in electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS2B-T is determined by strict equivalence across the following critical parameters:

• Connector Series & Base Design: Both parts belong to the Adam Tech MS series with identical base product number MS2B
• Position Count & Pitch: 2-position configuration with 0.079" (2.00mm) pitch maintained
• Physical Dimensions: Height of 0.138" (4.60mm) and connector type (Open Top, Female Sockets) identical
• Electrical Ratings: Voltage (250VAC) and current (1A) ratings unchanged
• Housing Material & Flammability: Polybutylene Terephthalate (PBT), Glass Filled with UL94 V-0 rating preserved
• Compliance Standards: ROHS3 compliance and MSL 1 rating maintained

The primary difference between MS2B-T and its substitute is the contact finish material: tin versus gold plating. This distinction does not affect mechanical compatibility or electrical performance within the specified ratings.

Parameter Comparison

Engineering Selection Recommendations

The MS2B-G serves as the direct substitute for the obsolete MS2B-T. Both components maintain identical mechanical compatibility and electrical performance specifications. The MS2B-G is currently in active production status with significantly higher inventory availability (16,006 units versus 641 units for the MS2B-T).

From a compliance perspective, both parts satisfy ROHS3 requirements and carry equivalent environmental ratings. The MS2B-G is classified under ECCN EAR99 with HTSUS code 8536.69.4040, whereas the MS2B-T is marked as OBSOLETE for export classification purposes.

The contact finish difference (tin versus gold flash) does not alter the electrical or mechanical interface. Selection between these parts should be based on component availability and procurement timeline, with the MS2B-G recommended for new designs and ongoing production due to its active status and superior stock position.

Frequently Asked Questions (FAQ)

Q: Are MS2B-T and MS2B-G mechanically interchangeable? A: Yes. Both connectors share identical pitch (2.00mm), position count (2), height (4.60mm), and connector type (Open Top, Female Sockets). They are direct mechanical replacements.

Q: Does the contact finish difference affect electrical performance? A: No. Both tin and gold flash finishes meet the specified voltage (250VAC) and current (1A) ratings. Contact finish does not alter the electrical interface within these parameters.

Q: Why is MS2B-T marked as obsolete? A: The MS2B-T has been discontinued by the manufacturer. The MS2B-G represents the current production equivalent and is the recommended substitute for procurement and design purposes.

Q: Are there any compliance differences between the two parts? A: Both parts are ROHS3 compliant with identical MSL ratings (1 - Unlimited). The MS2B-G carries active ECCN classification (EAR99) while MS2B-T is marked OBSOLETE for export purposes.

Q: What is the inventory status for each part? A: MS2B-T has 641 units available as new original stock. MS2B-G has 16,006 units available, providing significantly greater availability for production requirements.

Q: Can MS2B-G be used in existing designs originally specified for MS2B-T? A: Yes. The MS2B-G is a direct substitute with no design modifications required. Existing PCB layouts, mating connectors, and assembly processes remain compatible.
