MRS2-10-U-SMT Equivalent & Substitute Parts

Part Overview

The MRS2-10-U-SMT is a 10-position header connector manufactured by Adam Tech, designed for board-to-board applications with 1.0mm pitch surface mount configuration. This connector features female socket contacts with gold plating and is rated for 1A per contact at 250VAC. The product is currently active and widely used in general-purpose applications requiring compact, reliable interconnection solutions.

Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, while maintaining electrical and mechanical compatibility within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MRS2-10-U-SMT is determined by strict alignment of the following critical parameters:

• Connector Configuration: 10-position, 2-row layout with 1.0mm pitch mating and row spacing
• Contact Specification: Female socket contacts with gold flash finish
• Electrical Performance: 1A current rating per contact, 250VAC voltage rating
• Mounting & Termination: Surface mount with solder termination
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1 rating
• Operating Range: -40°C to 105°C temperature specification

The substitute part BC085-10-A-0390-L-C from GCT meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical pitch, row configuration, contact type, current and voltage ratings, temperature range, and compliance certifications. Packaging differences (Tube vs. Tape & Reel) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MRS2-10-U-SMT and BC085-10-A-0390-L-C are active products with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Availability and Lead Time: Inventory levels and supplier delivery schedules may influence part selection. The BC085-10-A-0390-L-C currently has higher stock availability (5221 pcs vs. 775 pcs).

Packaging Requirements: The MRS2-10-U-SMT is supplied in Tube packaging, while the BC085-10-A-0390-L-C is supplied in Tape & Reel format. Tape & Reel packaging is optimized for automated assembly processes, while Tube packaging is suitable for manual or lower-volume applications.

Compliance Certification: Both parts meet identical environmental and regulatory requirements, including REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Are MRS2-10-U-SMT and BC085-10-A-0390-L-C electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications: 10-position configuration, 1.0mm pitch, 1A per contact current rating, and 250VAC voltage rating. They are suitable for the same circuit applications.

Q: What is the difference between Header and Receptacle connector types in this context?

A: The MRS2-10-U-SMT is classified as a Header connector, while the BC085-10-A-0390-L-C is a Receptacle with bottom or top entry capability. Both are female socket contact types designed for board-to-board mating. The functional difference relates to mounting orientation and entry direction, not electrical performance.

Q: Does packaging format affect connector performance?

A: No. Tube and Tape & Reel packaging formats do not affect electrical or mechanical performance. Packaging selection is driven by assembly process requirements: Tape & Reel is standard for automated pick-and-place assembly, while Tube packaging is common for manual assembly or lower-volume production.

Q: Are both parts suitable for the full -40°C to 105°C operating temperature range?

A: Yes. Both the MRS2-10-U-SMT and BC085-10-A-0390-L-C are rated for continuous operation across the -40°C to 105°C temperature range.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 indicates the lowest moisture sensitivity classification. Components with this rating require no special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: Are both parts RoHS compliant?

A: Yes. Both connectors are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
