FTSH-115-01-F-D-K Equivalent & Substitute Parts

Part Overview

The FTSH-115-01-F-D-K is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This shrouded, cuttable header features 30 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing. The connector is actively produced and widely used in applications requiring reliable push-pull mating with keyed shroud protection. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in design and procurement scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTSH-115-01-F-D-K is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 30
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Shrouded
• Contact Length - Mating: 0.120" (3.05mm)
• Contact Length - Post: 0.090" (2.29mm)
• Overall Contact Length: 0.309" (7.86mm)
• Contact Shape: Square
• Insulation Material: Liquid Crystal Polymer (LCP)

The BD120-30-A-0305-0229-L-B from GCT meets these core electrical and mechanical requirements, enabling direct substitution in applications where the FTSH-115-01-F-D-K is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the FTSH-115-01-F-D-K and BD120-30-A-0305-0229-L-B are active products with ROHS3 compliance and UL94 V-0 flammability ratings. The primary differences between these parts are:

Contact material composition differs: the FTSH-115-01-F-D-K uses phosphor bronze with tin-plated posts, while the BD120-30-A-0305-0229-L-B uses brass with gold-plated posts. Contact finish on the post differs: tin versus gold plating.

Current rating differs: the FTSH-115-01-F-D-K is rated at 3.4A per contact, while the BD120-30-A-0305-0229-L-B is rated at 1A per contact. This represents a significant difference in current-carrying capacity.

Operating temperature range differs: the FTSH-115-01-F-D-K operates from -55°C to 125°C, while the BD120-30-A-0305-0229-L-B operates from -40°C to 105°C.

Connector type differs: the FTSH-115-01-F-D-K is cuttable, while the BD120-30-A-0305-0229-L-B is not.

Selection between these parts must account for application-specific requirements regarding current capacity, temperature extremes, and whether a cuttable connector is necessary.

Frequently Asked Questions (FAQ)

Q: Can the BD120-30-A-0305-0229-L-B directly replace the FTSH-115-01-F-D-K in all applications?

A: Direct substitution is possible only when the application does not require the higher current rating (3.4A per contact) of the FTSH-115-01-F-D-K, does not operate below -40°C or above 105°C, and does not require a cuttable connector design. The core electrical and mechanical interfaces are compatible.

Q: What is the significance of the contact material difference between phosphor bronze and brass?

A: Contact material affects electrical conductivity, spring characteristics, and durability under repeated mating cycles. Phosphor bronze provides superior spring properties and wear resistance compared to brass. This difference may influence connector longevity in high-cycle applications.

Q: Why is the current rating significantly lower for the BD120-30-A-0305-0229-L-B?

A: Current rating is determined by contact geometry, material composition, and thermal design. The BD120-30-A-0305-0229-L-B's lower 1A per contact rating reflects its design specifications. Applications requiring 3.4A per contact must use the FTSH-115-01-F-D-K.

Q: Does the difference in contact finish (tin versus gold on posts) affect compatibility?

A: Both tin and gold finishes are suitable for solder termination. Gold provides superior corrosion resistance and is preferred in high-reliability applications. Tin is cost-effective and adequate for standard industrial use. The choice depends on environmental exposure and reliability requirements.

Q: What does "cuttable" mean for the FTSH-115-01-F-D-K?

A: A cuttable connector allows the header to be separated into smaller segments after manufacturing, enabling custom pin counts. The BD120-30-A-0305-0229-L-B is not cuttable and must be used as a complete 30-position assembly.

Q: Are both parts suitable for pick-and-place assembly?

A: The BD120-30-A-0305-0229-L-B includes pick-and-place features. The FTSH-115-01-F-D-K specifications do not indicate pick-and-place capability. Packaging also differs: the FTSH-115-01-F-D-K is supplied in tubes, while the BD120-30-A-0305-0229-L-B is supplied in cut tape.
