FTS-120-03-FM-DV Equivalent & Substitute Parts

Part Overview

The FTS-120-03-FM-DV is a surface mount rectangular connector header manufactured by Samtec Inc., featuring 40 positions arranged in 2 rows with 0.050" (1.27mm) pitch. This cuttable header connector is designed for board-to-board or cable applications with push-pull fastening and solder termination. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory optimization, or specific mechanical or electrical parameter adjustments within the same connector family.

Substitute Part Grouping Explanation

Substitute parts for the FTS-120-03-FM-DV are identified based on strict electrical and mechanical parameter compatibility within the Samtec connector family. The substitution logic is based on the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 40
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Length - Mating: 0.065" (1.65mm)
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Current Rating: 3.4A per Contact
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Identified Substitutes:

1. FTS-120-03-F-DV - Differs only in contact finish thickness specification documentation; all functional and mechanical parameters are identical to the main part.

2. FTSH-120-03-F-DV - Differs in series designation (FTSH vs. FTS) and insulation height (0.099" vs. 0.034"); all other critical parameters including pitch, position count, contact specifications, and electrical ratings remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts—FTS-120-03-FM-DV, FTS-120-03-F-DV, and FTSH-120-03-F-DV—are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by specific design requirements:

FTS-120-03-FM-DV is the primary specification when standard insulation height of 0.034" (0.86mm) is required for compact board layouts.

FTS-120-03-F-DV provides identical functionality and mechanical compatibility to FTS-120-03-FM-DV and serves as a direct substitute when inventory or sourcing conditions favor this variant.

FTSH-120-03-F-DV is selected when increased insulation height of 0.099" (2.51mm) is necessary for design clearance or mechanical robustness. The FTSH series designation reflects this dimensional difference while maintaining all electrical and contact specifications.

All three parts maintain identical electrical performance with 3.4A per contact current rating, -55°C to 125°C operating temperature range, and gold-plated mating contacts on phosphor bronze material. Compliance certifications and moisture sensitivity levels are equivalent across all variants.

Frequently Asked Questions (FAQ)

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

A: Yes. FTS-120-03-F-DV is functionally and mechanically equivalent to FTS-120-03-FM-DV. All critical parameters including pitch, position count, contact specifications, electrical ratings, and compliance certifications are identical.

Q: What is the primary difference between FTS-120-03-FM-DV and FTSH-120-03-F-DV?

A: The primary difference is insulation height. FTS-120-03-FM-DV has an insulation height of 0.034" (0.86mm), while FTSH-120-03-F-DV has an insulation height of 0.099" (2.51mm). All other electrical and mechanical parameters remain equivalent.

Q: Can FTSH-120-03-F-DV be used in place of FTS-120-03-FM-DV in existing designs?

A: FTSH-120-03-F-DV can be used as a substitute only if the increased insulation height of 0.099" (2.51mm) does not conflict with board layout or mechanical constraints. The connector maintains identical electrical performance and contact specifications.

Q: Are all three parts RoHS compliant?

A: Yes. FTS-120-03-FM-DV, FTS-120-03-F-DV, and FTSH-120-03-F-DV are all ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the current rating for these connectors?

A: All three parts are rated for 3.4A per contact with an operating temperature range of -55°C to 125°C.

Q: Are these connectors suitable for high-reliability applications?

A: Yes. All three parts feature gold-plated mating contacts on phosphor bronze material, UL94 V-0 flammability certification, and ROHS3 compliance, making them suitable for industrial and high-reliability applications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.
