MS2H-2-T Mini Shunt 2.0mm 2-Position Connector Equivalent & Substitute Parts

Part Overview

The MS2H-2-T is a 2-position mini shunt connector manufactured by Adam Tech, featuring a closed-top design with pull handle grip and 2.0mm pitch. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The MS2H-2-T serves as a jumper connector for low-voltage signal routing and configuration applications. Due to its obsolete status, equivalent active-production alternatives must be evaluated based on electrical and mechanical compatibility parameters.

Substitute Part Grouping Explanation

Substitution of the MS2H-2-T is determined by strict equivalence across the following critical parameters:

Position Configuration: 2-position (1 x 2) grid layout
Pitch Spacing: 0.079" (2.00mm) center-to-center
Connector Type: Closed-top design with pull handle grip
Gender: Female sockets
Physical Dimensions: 0.429" (10.90mm) height
Current Capacity: 3A rating
Housing Material: Polyamide (PA66), Nylon 6/6
Flammability: UL94 V-2 compliance
Color: Black

The MS2H-2-G qualifies as a direct substitute based on identical mechanical and electrical parameters. The primary difference is the contact finish material (gold flash versus tin), which does not affect functional compatibility for standard signal-routing applications within the specified current and voltage parameters.

Engineering Selection Recommendations

The MS2H-2-G is the direct active-production equivalent for the obsolete MS2H-2-T. Selection is based on the following engineering criteria:

Product Status: The MS2H-2-G maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete MS2H-2-T.

Regulatory Compliance: Both parts maintain ROHS3 compliance and UL94 V-2 flammability certification, meeting current environmental and safety standards.

Mechanical Compatibility: Identical pitch spacing (2.00mm), position configuration (2-position), and physical dimensions (0.429" height) ensure direct mechanical interchangeability without PCB redesign or mechanical rework.

Electrical Equivalence: Both parts share identical current rating (3A) and housing material specifications, maintaining electrical performance within the same operational envelope.

Contact Finish Consideration: The MS2H-2-G uses gold flash contact finish compared to tin on the MS2H-2-T. Gold plating provides enhanced corrosion resistance and contact reliability, particularly in environments with moisture exposure or extended storage periods. This represents a performance improvement over the original tin finish.

Frequently Asked Questions (FAQ)

Q: Can the MS2H-2-G be used as a direct replacement for MS2H-2-T without PCB modification?

A: Yes. The MS2H-2-G is mechanically and electrically equivalent. Identical pitch spacing (2.00mm), position count (2-position), and physical dimensions (0.429" height) enable direct substitution without PCB redesign.

Q: What is the difference between the tin and gold contact finishes?

A: The MS2H-2-T uses tin contact finish, while the MS2H-2-G uses gold flash finish. Gold plating provides superior corrosion resistance and contact reliability, particularly in high-humidity or long-term storage applications. Both finishes support the 3A current rating.

Q: Are both parts RoHS compliant?

A: Yes. Both the MS2H-2-T and MS2H-2-G are ROHS3 compliant and meet current environmental regulations.

Q: Why is the MS2H-2-T classified as obsolete?

A: The MS2H-2-T has been discontinued by Adam Tech. The MS2H-2-G serves as the active-production replacement within the MS series.

Q: What is the MSL rating, and does it affect storage?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard component storage conditions apply without special moisture-control requirements.

Q: Are there packaging differences between the two parts?

A: The MS2H-2-T was available in standard packaging, while the MS2H-2-G is supplied in bulk packaging. Functional specifications remain identical regardless of packaging format.
