TSW-119-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-119-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 19-position, single-row header operates at 0.100" (2.54mm) pitch and is classified as an unshrouded, board-to-board or cable connector with solder termination and push-pull fastening. The part maintains active product status with 981 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this connector category, enabling component interchangeability in applications where the original part becomes unavailable or when design requirements permit alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-119-14-L-S is determined by alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header with Male Pin contacts
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Material: Thermoplastic or PBT
• Material Flammability Rating: UL94 V-0

The substitute part 4-103321-0-15 (TE Connectivity AMP Connectors) shares these core electrical and mechanical parameters. However, this substitute differs in position count (15 vs. 19), contact finish specifications, operating temperature range, and RoHS compliance status. Position count variance permits substitution only in applications where the reduced pin count meets functional requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSW-119-14-L-S maintains active product status with ROHS3 compliance and a wider operating temperature range (-55°C to 125°C). Selection of this part is appropriate for applications requiring RoHS3 compliance, extended temperature operation, or where 19-position connectivity is mandatory.

The substitute part 4-103321-0-15 is discontinued at DiGi Electronics and carries RoHS non-compliant status. This substitute is suitable only for legacy system maintenance or applications where RoHS compliance is not required. The reduced position count (15 vs. 19) and narrower operating temperature range (-65°C to 105°C) further restrict its applicability. The tin-lead contact finish and copper alloy material differ from the main part's gold-plated phosphor bronze contacts, affecting contact resistance and corrosion resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0-15 directly replace the TSW-119-14-L-S in new designs?

A: No. The substitute part is discontinued and RoHS non-compliant. New designs should specify the TSW-119-14-L-S or identify alternative active-status headers meeting equivalent electrical and mechanical parameters.

Q: What is the primary difference between these two connectors?

A: The main difference is position count: TSW-119-14-L-S provides 19 positions, while 4-103321-0-15 provides 15 positions. Secondary differences include contact finish (gold vs. tin-lead), operating temperature range, and RoHS compliance status.

Q: Are the pitch and mounting characteristics identical?

A: Yes. Both connectors share 0.100" (2.54mm) pitch, through-hole mounting, solder termination, and push-pull fastening. Both are single-row, unshrouded headers with square male pin contacts.

Q: Does the operating temperature difference affect substitution?

A: The TSW-119-14-L-S operates from -55°C to 125°C, while the substitute operates from -65°C to 105°C. Applications requiring operation above 105°C or below -65°C must use the main part. The substitute's narrower upper temperature limit is the primary constraint.

Q: Is RoHS compliance a factor in selecting between these parts?

A: Yes. The TSW-119-14-L-S is ROHS3 compliant; the substitute is RoHS non-compliant. Applications subject to RoHS regulations must use the main part or identify alternative compliant headers.

Q: Can I use the 4-103321-0-15 in a legacy system originally designed for the TSW-119-14-L-S?

A: Only if the application uses 15 or fewer of the 19 available positions and does not require RoHS compliance or extended temperature operation. Verify that the reduced pin count does not compromise system functionality.
