FTSH-105-04-F-DH-C Equivalent & Substitute Parts

Part Overview

The FTSH-105-04-F-DH-C is a surface mount, right-angle rectangular connector header manufactured by Samtec Inc. This 10-position connector operates at 3.4A per contact and maintains performance across -55°C to 125°C. The part is Active status and ROHS3 compliant, making it suitable for applications requiring board-to-board or cable interconnection with push-pull fastening. Substitute parts are identified when mounting type, contact configuration, or environmental requirements differ from the original specification.

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
• Contact Type and Material: Male pin contacts with phosphor bronze material and gold mating finish
• Electrical Performance: Identical 3.4A per contact current rating and -55°C to 125°C operating temperature range
• Fastening and Style: Push-pull fastening with board-to-board or cable connection capability
• Compliance: Both parts are ROHS3 compliant with UL94 V-0 flammability rating

The primary difference between the main part and substitute is the mounting type: the FTSH-105-04-F-DH-C uses surface mount right-angle termination, while the FTSH-105-04-L-D uses through-hole vertical mounting. This distinction allows selection based on PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FTSH-105-04-F-DH-C and FTSH-105-04-L-D maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by PCB assembly method and board layout constraints:

• FTSH-105-04-F-DH-C is specified for surface mount assembly with right-angle orientation, suitable for applications requiring low-profile board-to-board connections or cable interfaces on the PCB edge.

• FTSH-105-04-L-D is specified for through-hole assembly with vertical orientation, suitable for applications requiring mechanical stability through plated holes or where surface mount assembly is not feasible.

Both parts deliver identical electrical performance, contact reliability, and environmental operating range. The choice between them depends solely on the PCB design and manufacturing process capability.

Frequently Asked Questions (FAQ)

Q: Can FTSH-105-04-L-D replace FTSH-105-04-F-DH-C in the same application?

A: Substitution is possible only if the PCB layout and assembly process support through-hole mounting. The vertical orientation and post length of the FTSH-105-04-L-D differ from the surface mount right-angle configuration of the FTSH-105-04-F-DH-C. PCB footprint redesign is required.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts maintain 3.4A per contact current rating, -55°C to 125°C operating temperature, gold-plated mating contacts, and phosphor bronze contact material. Electrical performance is equivalent.

Q: What is the difference in contact finish thickness?

A: The FTSH-105-04-F-DH-C has 3.00µin (0.076µm) gold finish thickness on mating contacts, while the FTSH-105-04-L-D has 10.0µin (0.25µm). Both meet the same contact reliability and durability requirements for the specified applications.

Q: Do both parts support the same fastening method?

A: Yes. Both parts use push-pull fastening and are classified as cuttable headers within the FTSH series, allowing customization of position count if required.

Q: Are there inventory considerations for these parts?

A: The FTSH-105-04-F-DH-C has 1145 pcs in stock, while the FTSH-105-04-L-D has 1202 pcs in stock. Both are available as new original components in tube packaging.
