Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTS-118-04-L-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header, cuttable design with male pin contacts
• Position & Row Configuration: 36 positions arranged in 2 rows
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Electrical Performance: 3.4A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating and ROHS3 compliance
• Operating Range: -55°C to 125°C temperature specification

The FTSH-118-04-L-D qualifies as a substitute part because it maintains identical specifications across all critical electrical and mechanical parameters. Variations in overall contact length and insulation height do not affect functional compatibility in standard board-to-board applications, as these dimensions remain within acceptable tolerances for the connector interface.

Parameter Comparison

Engineering Selection Recommendations

Both FTS-118-04-L-D and FTSH-118-04-L-D are active products from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on specific application requirements regarding overall connector height and insulation profile. The FTS-118-04-L-D features a lower profile (0.274" overall contact length, 0.034" insulation height), while the FTSH-118-04-L-D provides an extended profile (0.339" overall contact length, 0.099" insulation height). Both maintain identical electrical performance, contact configuration, and environmental operating specifications. Inventory availability and lead time considerations may also influence part selection, with current stock levels at 982 units for FTS-118-04-L-D and 761 units for FTSH-118-04-L-D.

Frequently Asked Questions (FAQ)

Q: Can FTSH-118-04-L-D be used as a direct replacement for FTS-118-04-L-D?

A: Yes, FTSH-118-04-L-D qualifies as a functional substitute for FTS-118-04-L-D in applications where the increased overall contact length (0.339" versus 0.274") and insulation height (0.099" versus 0.034") do not create physical constraints on the PCB or enclosure. Both parts maintain identical electrical specifications, contact pitch, and environmental ratings.

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

A: The primary differences are dimensional. FTS-118-04-L-D is a low-profile variant, while FTSH-118-04-L-D is a higher-profile variant. All electrical parameters, contact configurations, and compliance certifications are identical.

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

A: Yes, both FTS-118-04-L-D and FTSH-118-04-L-D operate across the full -55°C to 125°C temperature range and carry UL94 V-0 flammability certification, making them suitable for demanding thermal environments.

Q: What is the significance of the series designation (FTS versus FTSH)?

A: The series designation indicates the connector profile family within Samtec's product line. FTS represents the standard low-profile header series, while FTSH represents the higher-profile variant. Both series share identical electrical and contact specifications for this 36-position configuration.

Q: Are both parts RoHS compliant?

A: Yes, both FTS-118-04-L-D and FTSH-118-04-L-D are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What current capacity should be considered for circuit design?

A: Both parts are rated for 3.4A per contact. Total circuit current capacity depends on the number of contacts utilized and the specific application's current distribution across the connector pins.
