TSW-114-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-114-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 14-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The connector is classified as Active product status and is fully RoHS3 compliant with UL94 V-0 flammability rating.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct functional replacement in board-to-board or cable connection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-114-14-L-S is determined by the following critical parameters:

• Connector Type: Header with male pin contacts
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Shape: Square
• Shrouding: Unshrouded
• Style: Board to Board or Cable

The identified substitute part 4-103321-8 (TE Connectivity AMP Connectors) shares these core electrical and mechanical characteristics. However, this part differs in position count (40 positions versus 14 positions) and product status (Obsolete versus Active). The 40-position configuration allows for breakaway functionality, enabling users to extract individual 14-position segments for applications requiring the TSW-114-14-L-S footprint and electrical interface.

Parameter Comparison

Engineering Selection Recommendations

The TSW-114-14-L-S remains the preferred selection for new designs due to its Active product status, ensuring long-term availability and manufacturer support. The part meets current RoHS3 compliance requirements and UL94 V-0 flammability standards.

The substitute part 4-103321-8 is classified as Obsolete. While it shares core electrical and mechanical compatibility parameters, its obsolete status indicates discontinued manufacturing and potential supply constraints. Selection of this substitute should be limited to legacy system maintenance or applications where breakaway functionality provides specific design advantages.

Key differences affecting selection include:

• Operating temperature range: TSW-114-14-L-S supports -55°C ~ 125°C; 4-103321-8 supports -65°C ~ 105°C
• Contact finish: TSW-114-14-L-S features gold-plated mating contacts; 4-103321-8 uses tin plating
• Position count: 4-103321-8 provides 40 positions with breakaway capability versus 14 fixed positions

Both parts maintain UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 40-position 4-103321-8 directly replace the 14-position TSW-114-14-L-S?

A: The 4-103321-8 shares compatible pitch (0.100"), contact type (male pin), mounting method (through-hole solder), and contact geometry (square). The 40-position configuration with breakaway design allows extraction of 14-position segments. However, PCB footprint compatibility must be verified, as the overall connector length differs.

Q: What are the key electrical compatibility factors?

A: Both connectors operate at 0.100" (2.54mm) pitch with square male pin contacts, solder termination, and unshrouded design. Contact material differs (phosphor bronze versus copper alloy) and contact finish varies (gold mating versus tin mating), which may affect electrical performance in specific applications.

Q: Why is the TSW-114-14-L-S preferred over the substitute?

A: The TSW-114-14-L-S maintains Active product status, ensuring ongoing manufacturer support and supply availability. The substitute 4-103321-8 is Obsolete, indicating discontinued production. For new designs, the Active part is the recommended selection.

Q: Are there temperature rating differences?

A: Yes. The TSW-114-14-L-S operates across -55°C ~ 125°C, while the 4-103321-8 operates across -65°C ~ 105°C. Applications requiring the full upper temperature range of 125°C must use the TSW-114-14-L-S.

Q: Do both parts meet current compliance standards?

A: Both parts are ROHS3 compliant, UL94 V-0 rated, and classified as MSL 1 (Unlimited moisture sensitivity). Both meet current regulatory requirements for new applications.
