FTS-142-04-L-D Equivalent & Substitute Parts

Part Overview

The FTS-142-04-L-D is an 84-position rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This cuttable header features a 0.050" (1.27mm) pitch with dual rows and unshrouded design, utilizing phosphor bronze contacts with gold mating finish. The connector maintains Active product status and is ROHS3 compliant, making it suitable for applications requiring reliable interconnection across a wide temperature range of -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTS-142-04-L-D is determined by strict alignment of the following critical parameters:

• Number of Positions: 84 positions (non-negotiable)
• Pitch - Mating: 0.050" (1.27mm) (non-negotiable)
• Number of Rows: 2 rows (non-negotiable)
• Connector Type: Header, Cuttable (non-negotiable)
• Contact Type: Male Pin (non-negotiable)
• Mounting Type: Through Hole (non-negotiable)
• Termination: Solder (non-negotiable)
• Contact Material: Phosphor Bronze (non-negotiable)
• Contact Finish - Mating: Gold (non-negotiable)
• Insulation Material: Liquid Crystal Polymer (LCP) (non-negotiable)
• Operating Temperature Range: -55°C ~ 125°C (non-negotiable)
• Current Rating: 3.4A per Contact (non-negotiable)
• RoHS Status: ROHS3 Compliant (non-negotiable)

The FTSH-142-04-L-D qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. Variations in Overall Contact Length and Insulation Height do not affect functional compatibility within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the FTS-142-04-L-D and FTSH-142-04-L-D maintain Active product status with full ROHS3 compliance and UL94 V-0 material flammability certification. Selection between these parts should be based on PCB layout requirements and available board space. The FTS-142-04-L-D features a lower overall contact length of 0.274" (6.96mm) with minimal insulation height of 0.034" (0.86mm), suitable for applications with space constraints. The FTSH-142-04-L-D provides increased overall contact length of 0.339" (8.60mm) and insulation height of 0.099" (2.51mm), offering enhanced mechanical stability and clearance for densely populated boards. Both parts deliver identical electrical performance with 3.4A per contact current rating across the full -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the FTSH-142-04-L-D be used as a direct replacement for the FTS-142-04-L-D?

A: Yes. Both connectors share identical electrical specifications, pitch, position count, contact material, and finish specifications. The primary difference is mechanical profile. Verify PCB layout accommodates the increased insulation height of 0.099" (2.51mm) on the FTSH variant before substitution.

Q: What is the significance of the different Overall Contact Length values?

A: The FTS-142-04-L-D has an Overall Contact Length of 0.274" (6.96mm), while the FTSH-142-04-L-D measures 0.339" (8.60mm). This difference affects board-to-board spacing and mating depth. Confirm your application's mechanical envelope supports the selected variant.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the FTS-142-04-L-D and FTSH-142-04-L-D operate across -55°C to 125°C, with identical current ratings of 3.4A per contact and UL94 V-0 material certification.

Q: What does the "Cuttable" designation mean?

A: Both connectors feature cuttable header design, allowing the connector strip to be cut to the required number of positions while maintaining electrical and mechanical integrity at the cut points.

Q: Are these connectors RoHS compliant?

A: Yes. Both the FTS-142-04-L-D and FTSH-142-04-L-D are ROHS3 compliant, meeting current environmental and material restriction requirements.

Q: What is the pitch specification, and why is it critical?

A: Both connectors feature a 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing. This pitch is fundamental to PCB footprint design and mating connector compatibility. Substitution requires identical pitch specifications.
