Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FTS-105-04-L-D are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Current Rating: 3.4A per Contact
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze

Mechanical Parameters:

• Connector Type: Header, Cuttable
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Liquid Crystal Polymer (LCP)

Environmental & Compliance Parameters:

• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Product Status: Active

The identified substitutes (FTSH-105-04-L-D and FTSH-105-04-LM-D) maintain all critical electrical and mechanical parameters. Variations in Overall Contact Length and Insulation Height do not affect functional compatibility in standard through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FTS-105-04-L-D, FTSH-105-04-L-D, and FTSH-105-04-LM-D—are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. They share identical electrical specifications, contact configurations, and environmental ratings.

The primary differences are dimensional: the FTSH series parts feature increased Overall Contact Length (0.339" vs. 0.274") and Insulation Height (0.099" vs. 0.034"). These dimensional variations do not affect electrical performance or standard PCB mounting compatibility. Selection between these parts depends on specific board layout requirements and available PCB through-hole depth.

All parts are suitable for applications requiring reliable solder termination, push-pull fastening, and operation across the -55°C to 125°C temperature range with 3.4A per-contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can FTSH-105-04-L-D and FTSH-105-04-LM-D be used interchangeably with FTS-105-04-L-D?

A: Yes. All three parts maintain identical electrical specifications, pitch, position count, contact type, and current rating. The dimensional differences in Overall Contact Length and Insulation Height do not affect functional compatibility in standard through-hole applications.

Q: What is the difference between FTS-105-04-L-D and FTSH-105-04-L-D?

A: The primary differences are dimensional. FTS-105-04-L-D has an Overall Contact Length of 0.274" (6.96mm) and Insulation Height of 0.034" (0.86mm). FTSH-105-04-L-D has an Overall Contact Length of 0.339" (8.60mm) and Insulation Height of 0.099" (2.51mm). Electrical performance and contact specifications are identical.

Q: Are all three parts RoHS compliant?

A: Yes. FTS-105-04-L-D, FTSH-105-04-L-D, and FTSH-105-04-LM-D are all ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What is the current rating for these connectors?

A: All three parts are rated for 3.4A per contact, suitable for standard low-to-medium current applications.

Q: Do these connectors require any special handling or storage?

A: FTS-105-04-L-D has Moisture Sensitivity Level (MSL) listed as Not Applicable. FTSH-105-04-L-D and FTSH-105-04-LM-D have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the operating temperature range?

A: All three parts operate across -55°C to 125°C, suitable for industrial and commercial applications.

Q: Can these connectors be cut to reduce the number of positions?

A: Yes. All three parts are designated as "Cuttable" headers, allowing modification of the connector to accommodate fewer positions as required by specific circuit designs.
