TE Connectivity AMP Connectors 881545-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 881545-2 is a 2-position shunt connector from the AMPMODU series, designed for applications requiring female socket connections at 0.100" (2.54mm) pitch. This component features an open top grip design with gold-plated contacts rated for 3A current capacity. The part is actively manufactured and RoHS compliant, making it suitable for modern electronic assemblies. Substitute parts may be required due to inventory constraints, design modifications, or application-specific requirements for alternative housing configurations or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 881545-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 2 (1 x 2)
• Pitch: 0.100" (2.54mm)
• Gender: Female Sockets
• Contact Finish: Gold
• Current Rating: 3A
• Color: Black
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowable Differences):

• Housing Type: Open Top or Closed Top configurations
• Height: Varies by design
• Housing Material: Different thermoplastic or polyamide compositions
• Voltage Rating: Different ratings acceptable based on application requirements
• Contact Finish Thickness: Different specifications acceptable
• Manufacturer and Series designation

The Adam Tech MSBH-G qualifies as a substitute part based on matching all mandatory parameters while differing in housing configuration (closed top versus open top) and housing material composition.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 881545-2 and Adam Tech MSBH-G are active products with equivalent electrical specifications for 2-position, 0.100" pitch shunt connector applications. Selection between these parts is based on the following engineering considerations:

TE Connectivity 881545-2 Selection Criteria:

• Applications requiring open top grip housing configuration
• Designs with height constraints of 0.429" (10.90mm) or less
• Preference for glass-filled thermoplastic housing material
• RoHS compliance requirement (standard RoHS)

Adam Tech MSBH-G Selection Criteria:

• Applications requiring closed top grip housing configuration
• Designs accommodating height of 0.531" (13.50mm)
• Preference for polyamide (PA66) nylon housing material
• ROHS3 compliance requirement
• Applications requiring explicit 250VAC voltage rating specification

Both parts maintain identical current rating (3A), contact finish material (gold), flammability rating (UL94 V-0), and moisture sensitivity level (MSL 1). The primary differentiators are housing type, height, housing material composition, and voltage rating specification.

Frequently Asked Questions (FAQ)

Q: Can the Adam Tech MSBH-G directly replace the TE Connectivity 881545-2 in existing designs?

A: Direct replacement is possible if the application accommodates the height difference (0.531" versus 0.429") and the closed top housing configuration is compatible with the insertion method. The electrical specifications are equivalent.

Q: What is the significance of the housing type difference (open top versus closed top)?

A: Open top housings allow insertion from the top and are typically used in applications with vertical insertion. Closed top housings provide different insertion geometry and may offer improved contact retention in certain applications. Design verification is required to confirm compatibility with the specific insertion mechanism.

Q: Are there voltage rating implications when substituting these parts?

A: The TE Connectivity 881545-2 does not specify a voltage rating, while the Adam Tech MSBH-G specifies 250VAC. For applications requiring explicit voltage rating documentation, the Adam Tech part provides this specification. For applications without voltage rating requirements, both parts are functionally equivalent.

Q: How do the housing materials differ in performance characteristics?

A: The TE Connectivity 881545-2 uses glass-filled thermoplastic, while the Adam Tech MSBH-G uses polyamide (PA66) nylon 6/6. Both materials meet UL94 V-0 flammability requirements. Material selection depends on specific environmental and mechanical requirements of the application.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both parts are RoHS compliant. The TE Connectivity 881545-2 carries standard RoHS compliance, while the Adam Tech MSBH-G carries ROHS3 compliance, which represents the current iteration of RoHS regulations. Both are acceptable for modern applications requiring RoHS compliance.

Q: Are the contact finish specifications equivalent?

A: Both parts feature gold contact finish. The TE Connectivity 881545-2 specifies 30.0µin (0.76µm) thickness, while the Adam Tech MSBH-G specifies flash plating. Both provide gold contact surfaces suitable for 3A current applications. Flash plating is a thin gold layer applied over base metal.

Q: What is the moisture sensitivity level (MSL) and why is it important?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying inventory and assembly processes.
