Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTSH-120-01-L-D-FC is determined by strict alignment of the following critical parameters:

• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• 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

Substitute parts are grouped into two categories:

Category 1: Direct Electrical and Mechanical Equivalents (FTSH Series)

• FTSH-120-01-L-D
• FTSH-120-01-LM-D
• FTSH-120-01-L-D-K

These parts maintain identical electrical specifications, contact geometry, pitch, and thermal ratings. Variations exist only in shrouding design or moisture sensitivity classification.

Category 2: Functional Equivalent with Design Variation (FTS Series)

• FTS-120-01-L-D-P

This part maintains core electrical parameters and contact specifications but differs in overall contact length and insulation height due to series design differences. It includes Pick and Place features for automated assembly applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original FTSH-120-01-L-D-FC specification.

FTSH-120-01-L-D is the primary direct substitute, offering identical electrical and mechanical specifications with higher inventory availability (2000 units). This part is suitable for applications requiring unshrouded connector geometry.

FTSH-120-01-L-D-K provides an alternative with keying shroud features, maintaining all electrical parameters while adding mechanical polarization. This variant is appropriate for applications requiring connector orientation control.

FTSH-120-01-LM-D maintains full electrical equivalence with the original part and is suitable where moisture sensitivity classification differences are acceptable.

FTS-120-01-L-D-P is a functional equivalent from the FTS series with reduced overall contact length (0.244" versus 0.309") and lower insulation height (0.034" versus 0.099"). This part includes Pick and Place features for automated assembly. Selection of this variant requires verification that reduced contact length and insulation height are compatible with the target PCB design and mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can FTSH-120-01-L-D replace FTSH-120-01-L-D-FC directly?

A: Yes. FTSH-120-01-L-D is electrically and mechanically equivalent. Both parts share identical pitch (0.050"), position count (40), row configuration (2), contact material (Phosphor Bronze), contact finish (Gold), operating temperature range (-55°C to 125°C), and current rating (3.4A per contact). The primary difference is inventory availability.

Q: What is the difference between FTSH-120-01-L-D-K and FTSH-120-01-L-D?

A: FTSH-120-01-L-D-K includes a keying shroud feature, providing mechanical polarization to prevent incorrect connector mating. All electrical specifications remain identical. The shrouded design adds physical protection to the contact area.

Q: Can FTS-120-01-L-D-P be used in place of FTSH-120-01-L-D-FC?

A: FTS-120-01-L-D-P maintains electrical compatibility but differs in physical dimensions. Overall contact length is reduced from 0.309" to 0.244", and insulation height is reduced from 0.099" to 0.034". These dimensional differences may affect PCB layout and mating connector compatibility. Verification against specific board design requirements is necessary before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the regulatory status of FTSH-120-01-L-D-FC.

Q: What does the "Cuttable" connector type mean?

A: Cuttable connectors can be separated into individual positions or smaller groups through mechanical cutting, allowing customization of the final connector configuration for specific application requirements.

Q: Do all substitute parts support the same current rating?

A: Yes. All substitute parts support 3.4A per contact, identical to the original FTSH-120-01-L-D-FC specification.
