Key Parameters

Substitute Part Grouping Explanation

The FTSH-104-04-L-D qualifies as a substitute for the FTS-104-04-L-D based on the following critical parameters:

Matching Parameters:

• Connector type: Header, Cuttable
• Contact type: Male Pin
• Number of positions: 8
• Number of rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row spacing - Mating: 0.050" (1.27mm)
• Mounting type: Through Hole
• Termination: Solder
• Contact shape: Square
• Contact finish - Mating: Gold
• Contact finish thickness - Mating: 10.0µin (0.25µm)
• Contact finish - Post: Tin
• Contact material: Phosphor Bronze
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• Current rating: 3.4A per Contact
• RoHS status: ROHS3 Compliant

Differences:

• Overall contact length: FTS-104-04-L-D is 0.274" (6.96mm); FTSH-104-04-L-D is 0.339" (8.60mm)
• Insulation height: FTS-104-04-L-D is 0.034" (0.86mm); FTSH-104-04-L-D is 0.099" (2.51mm)
• Moisture sensitivity level: FTS-104-04-L-D is Not Applicable; FTSH-104-04-L-D is 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

Both the FTS-104-04-L-D and FTSH-104-04-L-D are active products manufactured by Samtec Inc. and maintain identical electrical and thermal specifications. Both connectors are ROHS3 compliant and rated for -55°C to 125°C operation with 3.4A per contact current capacity.

The primary distinction between these parts is mechanical geometry. The FTSH-104-04-L-D features increased overall contact length (0.339" versus 0.274") and insulation height (0.099" versus 0.034"), resulting in a taller connector profile. This geometric difference may affect PCB layout compatibility and mating depth with corresponding receptacles.

Selection between these parts depends on board-to-board spacing requirements and mechanical clearance constraints. The FTSH-104-04-L-D offers greater availability with 2792 units in stock compared to 656 units for the FTS-104-04-L-D. Both parts carry identical compliance certifications and electrical ratings, making them functionally equivalent within their respective mechanical envelopes.

Frequently Asked Questions (FAQ)

Q: Can FTSH-104-04-L-D be used as a direct replacement for FTS-104-04-L-D?

A: Electrical and thermal compatibility is confirmed. However, the FTSH-104-04-L-D has a taller profile (0.339" overall contact length versus 0.274"). Substitution is valid only if PCB layout and mating receptacle clearance accommodate the increased height.

Q: What are the key differences between these two connectors?

A: The connectors share identical pitch (0.050"), contact configuration (8 positions, 2 rows), contact materials, and electrical ratings. The FTSH-104-04-L-D has greater overall contact length and insulation height, affecting mechanical fit and board spacing.

Q: Are both parts RoHS compliant?

A: Yes, both FTS-104-04-L-D and FTSH-104-04-L-D are ROHS3 compliant.

Q: What is the current rating for each contact?

A: Both connectors are rated for 3.4A per contact.

Q: Do these connectors have different operating temperature ranges?

A: No, both parts operate across the identical temperature range of -55°C to 125°C.

Q: Which part has better availability?

A: The FTSH-104-04-L-D has higher inventory availability with 2792 units in stock compared to 656 units for the FTS-104-04-L-D.
