TSW-103-14-S-D-LL Equivalent & Substitute Parts

Part Overview

The TSW-103-14-S-D-LL is an active rectangular connector header manufactured by Samtec Inc. This through-hole vertical header features 6 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable interconnection applications. The connector utilizes kinked pin solder termination with push-pull fastening and operates across -55°C to 125°C. Finding equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative sourcing strategies while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-103-14-S-D-LL is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (6) and row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Style (Board to Board or Cable)
• Shrouding status (Unshrouded)
• Fastening mechanism (Push-Pull)
• Contact material (Phosphor Bronze)
• Flammability rating (UL94 V-0)

The substitute part 87227-3 (TE Connectivity AMP Connectors) meets these core substitution criteria. Both parts share identical mating pitch, row configuration, position count, mounting type, and fastening approach. Variations in secondary parameters such as contact length dimensions, insulation height, contact finish thickness, and operating temperature range are within acceptable tolerance for mechanical and electrical interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-103-14-S-D-LL and 87227-3 are active products with UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The TSW-103-14-S-D-LL carries ROHS3 compliance, while the 87227-3 is not applicable for RoHS but is REACH affected. Selection between these parts should be based on specific application requirements regarding operating temperature range, insulation material specifications, and regulatory compliance mandates. The TSW-103-14-S-D-LL supports a wider upper temperature limit (-55°C to 125°C versus -65°C to 105°C), making it suitable for higher-temperature environments. The 87227-3 offers extended lower temperature capability. Both parts maintain identical mating pitch, position count, and mechanical interface geometry, ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 87227-3 be used as a direct replacement for the TSW-103-14-S-D-LL on existing PCBs?

A: Yes, both connectors share identical mating pitch (0.100" / 2.54mm), position count (6), row configuration (2 rows), and row spacing (0.100" / 2.54mm). PCB footprints designed for the TSW-103-14-S-D-LL will accommodate the 87227-3 without modification. Minor dimensional variations in contact length and insulation height do not affect mechanical seating or electrical performance in standard applications.

Q: What are the key differences between these two connector models?

A: Primary differences include operating temperature range (TSW-103-14-S-D-LL: -55°C to 125°C; 87227-3: -65°C to 105°C), insulation material (PBT versus Thermoplastic), contact post finish (Tin versus Gold), and RoHS compliance status (ROHS3 Compliant versus Not Applicable). These differences may influence selection based on environmental conditions and regulatory requirements.

Q: Are there any compatibility concerns with mating connectors?

A: Both parts utilize identical 0.100" (2.54mm) mating pitch and push-pull fastening mechanisms. Mating connectors designed for standard 2.54mm pitch headers will interface with either part without compatibility issues.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 (Unlimited) indicates that both connectors have unlimited shelf life and do not require special moisture control during storage or handling. This simplifies inventory management and reduces procurement constraints.

Q: How do the contact finish specifications affect performance?

A: The TSW-103-14-S-D-LL features gold-plated mating contacts with tin-plated posts, while the 87227-3 uses gold plating on both mating and post contacts. Gold plating provides superior corrosion resistance and contact reliability. The TSW-103-14-S-D-LL's tin-plated posts are suitable for standard solder reflow processes. Both finishes are appropriate for typical through-hole soldering applications.
