FTSH-105-02-F-DH Equivalent & Substitute Parts

Part Overview

The FTSH-105-02-F-DH is a surface mount rectangular connector header manufactured by Samtec Inc. This right-angle header features 10 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing, designed for board-to-board or cable connections. The connector is actively produced and maintains full inventory availability. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the FTSH series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the FTSH-105 series is determined by the following critical parameters:

• Pitch and Position Count: Both main and substitute parts maintain 0.050" (1.27mm) mating pitch with 10 positions in 2 rows
• Mounting Configuration: Both are surface mount, right-angle headers
• Contact System: Both use male pin contacts with phosphor bronze material
• Electrical Rating: Both support 3.4A per contact
• Temperature Range: Both operate across -55°C ~ 125°C
• Compliance: Both are ROHS3 compliant with UL94 V-0 flammability rating
• Insulation Material: Both use Liquid Crystal Polymer (LCP)

The FTSH-105-02-L-DH differs from the main part only in contact finish thickness on the mating surface (10.0µin versus 3.00µin), which does not affect functional compatibility or electrical performance within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the FTSH-105-02-F-DH and FTSH-105-02-L-DH are active products with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on contact finish thickness requirements for specific application environments. The FTSH-105-02-L-DH provides increased gold plating thickness (10.0µin) compared to the FTSH-105-02-F-DH (3.00µin), which may be beneficial in high-cycle mating applications or corrosive environments. Both parts maintain identical electrical performance, mechanical compatibility, and temperature operating range. Inventory availability should be evaluated based on procurement lead time requirements.

Frequently Asked Questions (FAQ)

Q: Are FTSH-105-02-F-DH and FTSH-105-02-L-DH mechanically interchangeable?

A: Yes. Both connectors share identical mounting type (surface mount, right angle), position count (10), row configuration (2 rows), and pitch spacing (0.050"). They mount identically on PCBs and mate with the same receptacle connectors.

Q: What is the difference between these two parts?

A: The primary difference is contact finish thickness on the mating surface. FTSH-105-02-F-DH has 3.00µin gold plating, while FTSH-105-02-L-DH has 10.0µin gold plating. All other electrical and mechanical specifications are identical.

Q: Do both parts support the same current and voltage ratings?

A: Yes. Both parts are rated for 3.4A per contact and operate across the same temperature range of -55°C ~ 125°C.

Q: Are both parts RoHS compliant?

A: Yes. Both FTSH-105-02-F-DH and FTSH-105-02-L-DH are ROHS3 compliant with UL94 V-0 flammability rating.

Q: Can I use these connectors in high-cycle mating applications?

A: Both parts are suitable for board-to-board or cable connections. The increased gold plating thickness of the FTSH-105-02-L-DH may provide enhanced durability in high-cycle mating scenarios.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special storage requirements.
