FTMH-105-03-F-DH Equivalent & Substitute Parts

Part Overview

The FTMH-105-03-F-DH is a rectangular connector header manufactured by Samtec Inc., designed for surface mount, right-angle board-to-board applications. This 10-position connector operates at 0.039" (1.00mm) pitch and is rated for 2.8A per contact across an operating temperature range of -55°C to 125°C. The part is currently active in production and maintains full RoHS3 compliance with UL94 V-0 flammability rating. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility is required.

Substitute Part Grouping Explanation

Substitution eligibility for the FTMH-105-03-F-DH is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.039" (1.00mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.039" (1.00mm)
• Mounting Type: Surface Mount, Right Angle
• Style: Board to Board
• Shrouding: Unshrouded
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Material: Liquid Crystal Polymer (LCP)

Parameter Comparison

Engineering Selection Recommendations

Both the FTMH-105-03-F-DH and BC057-10-A-A-0150-L-C are active production parts with full RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on application-specific requirements:

The FTMH-105-03-F-DH supports higher current capacity (2.8A per contact) and extended operating temperature range (-55°C to 125°C), making it suitable for demanding industrial and aerospace applications.

The BC057-10-A-A-0150-L-C provides a rated voltage specification (250VAC/DC) and is available in Tape & Reel packaging, which may be preferred for high-volume manufacturing environments. Its current rating of 1A per contact and operating temperature range of -40°C to 105°C are appropriate for standard commercial applications.

Both parts maintain identical mechanical and electrical interface specifications for the critical substitution parameters, ensuring PCB layout compatibility and mating connector interchangeability.

Frequently Asked Questions (FAQ)

Q: Are the FTMH-105-03-F-DH and BC057-10-A-A-0150-L-C mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.039" / 1.00mm), position count (10), row configuration (2 rows), mounting type (surface mount right-angle), and contact geometry (square male pins). PCB footprints and mating connector compatibility are identical.

Q: What are the differences in electrical performance between these parts?

A: The FTMH-105-03-F-DH is rated for 2.8A per contact with an operating temperature range of -55°C to 125°C. The BC057-10-A-A-0150-L-C is rated for 1A per contact with an operating temperature range of -40°C to 105°C and includes a specified voltage rating of 250VAC/DC. Application requirements determine which part is appropriate.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, and maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference in packaging between these parts?

A: The FTMH-105-03-F-DH is supplied in Tube packaging, while the BC057-10-A-A-0150-L-C is supplied in Tape & Reel (TR) packaging. Tape & Reel is typically preferred for automated assembly processes.

Q: Are there dimensional differences that could affect PCB layout?

A: Contact length and insulation height show minor variations. The FTMH-105-03-F-DH has a contact length of 0.065" (1.65mm) and insulation height of 0.125" (3.18mm), while the BC057-10-A-A-0150-L-C has a contact length of 0.059" (1.50mm) and insulation height of 0.122" (3.10mm). These differences are within typical manufacturing tolerances for board-to-board connectors and do not affect standard PCB design compatibility.
