FTMH-110-02-F-DV Equivalent & Substitute Parts

Part Overview

The FTMH-110-02-F-DV is a rectangular connector header manufactured by Samtec Inc., designed for surface mount board-to-board applications. This 20-position connector operates across a wide temperature range of -55°C to 125°C and is classified as Active product status.

Substitute Part Grouping Explanation

The BC050-20A-K0-0200-0160-0480-LB qualifies as a substitute for the FTMH-110-02-F-DV based on the following critical parameters:

Connector Type & Contact Configuration: Both are male pin headers with identical 20-position, 2-row configuration
Pitch Specifications: Both maintain 0.039" (1.00mm) mating pitch and row spacing
Mounting & Termination: Both are surface mount, solder-terminated connectors with push-pull fastening
Insulation Material: Both utilize Liquid Crystal Polymer (LCP)
Contact Finish: Both feature gold-plated mating contacts
Compliance: Both are ROHS3 compliant with UL94 V-0 flammability rating
Moisture Sensitivity: Both rated MSL 1 (Unlimited)

Substitution is valid where the operating temperature range and current rating requirements of the application fall within the overlapping specifications of both components.

Engineering Selection Recommendations

Both the FTMH-110-02-F-DV and BC050-20A-K0-0200-0160-0480-LB are Active status products with ROHS3 compliance and UL94 V-0 flammability certification, qualifying them for equivalent use in applications meeting the following conditions:

Operating temperature range must not exceed -40°C to 105°C (the overlapping specification window)
Current per contact must not exceed 1A (the lower rating of the substitute)
Packaging format (Tube vs. Tape & Reel) should align with manufacturing and assembly requirements

The FTMH-110-02-F-DV provides superior current handling (2.8A per contact) and extended temperature range (-55°C to 125°C), making it the preferred choice for high-current or extreme-temperature applications. The BC050-20A-K0-0200-0160-0480-LB is suitable for standard industrial applications within its specified operating parameters.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if BC050-20A-K0-0200-0160-0480-LB can substitute for FTMH-110-02-F-DV?

A: The substitute must match the following: 20-position, 2-row configuration; 0.039" (1.00mm) pitch and row spacing; male pin header; surface mount, solder-terminated; push-pull fastening; LCP insulation; gold-plated mating contacts; and UL94 V-0 flammability rating. Both parts meet these criteria.

Q: Are there any parameter differences that limit substitution?

A: Yes. The BC050-20A-K0-0200-0160-0480-LB has a lower current rating (1A per contact vs. 2.8A) and a narrower operating temperature range (-40°C to 105°C vs. -55°C to 125°C). Applications requiring higher current or extended temperature operation must use the FTMH-110-02-F-DV.

Q: How do the physical dimensions compare?

A: The contact length at mating differs slightly (0.075" for FTMH-110-02-F-DV vs. 0.079" for BC050-20A-K0-0200-0160-0480-LB). The insulation height is notably different (0.059" vs. 0.039"), which may affect board layout and mating connector selection.

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

A: The FTMH-110-02-F-DV is supplied in Tube packaging, while the BC050-20A-K0-0200-0160-0480-LB is supplied in Tape & Reel (TR) format. Packaging choice depends on manufacturing volume and assembly line requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the FTMH-110-02-F-DV and BC050-20A-K0-0200-0160-0480-LB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
