Key Parameters

Substitute Part Grouping Explanation

The FTS-120-03-L-DV qualifies as a substitute for the FTSH-120-02-F-DV based on the following critical parameters:

• Pitch - Mating: Both parts maintain 0.050" (1.27mm) pitch
• Number of Positions: Both parts provide 40 positions
• Number of Rows: Both parts feature 2 rows
• Row Spacing - Mating: Both parts maintain 0.050" (1.27mm) spacing
• Contact Type: Both are male pin headers
• Mounting Type: Both are surface mount
• Termination: Both use solder termination
• Current Rating: Both support 3.4A per contact
• Operating Temperature: Both operate across -55°C ~ 125°C
• Material Flammability Rating: Both meet UL94 V-0
• Insulation Material: Both use Liquid Crystal Polymer (LCP)
• Contact Material: Both use Phosphor Bronze
• Contact Finish - Mating: Both feature gold plating
• Contact Finish - Post: Both feature tin plating
• RoHS Status: Both are ROHS3 Compliant
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)

Differences exist in contact length dimensions and packaging format, which do not affect electrical compatibility in applications where these dimensional variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both the FTSH-120-02-F-DV and FTS-120-03-L-DV are active products manufactured by Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on:

Packaging Format: The FTSH-120-02-F-DV is supplied in tube packaging, while the FTS-120-03-L-DV is supplied in bulk packaging. Choose based on procurement and assembly requirements.

Physical Dimensions: The FTS-120-03-L-DV features a lower insulation height (0.034" vs. 0.099") and shorter mating contact length (0.065" vs. 0.075"). These dimensional differences may affect PCB layout and mating depth requirements. Verify compatibility with your specific application geometry.

Contact Finish Thickness: The FTS-120-03-L-DV provides thicker gold plating on mating contacts (10.0µin vs. 3.00µin), which may offer enhanced durability in high-cycle mating applications.

Both parts maintain identical electrical performance, current ratings, temperature ranges, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can FTS-120-03-L-DV be used as a direct replacement for FTSH-120-02-F-DV?

A: Electrical compatibility is maintained. However, the dimensional differences in contact length and insulation height require verification against your PCB layout and mating connector specifications. Confirm that the lower profile of the FTS-120-03-L-DV is compatible with your application.

Q: What is the difference between tube and bulk packaging?

A: Tube packaging (FTSH-120-02-F-DV) provides individual component protection and is suitable for lower-volume or manual assembly operations. Bulk packaging (FTS-120-03-L-DV) is optimized for high-volume automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes, both FTSH-120-02-F-DV and FTS-120-03-L-DV are ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: Do both parts support the same current rating?

A: Yes, both parts support 3.4A per contact and operate across the same temperature range of -55°C to 125°C.

Q: What is the significance of the contact finish thickness difference?

A: The FTS-120-03-L-DV features thicker gold plating (10.0µin) compared to the FTSH-120-02-F-DV (3.00µin). Thicker plating may provide improved wear resistance in applications with frequent mating cycles, though both meet the same electrical specifications.
