TSW-119-14-F-D Equivalent & Substitute Parts

Part Overview

The TSW-119-14-F-D is a Classic PCB Header Strip manufactured by Samtec Inc., designed for through-hole board-to-board or cable connections. This unshrouded header features 38 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector utilizes male pins with gold-plated mating contacts and tin-plated posts, constructed from phosphor bronze with polybutylene terephthalate (PBT) insulation. The part maintains Active product status with full inventory availability.

Substitute parts become necessary when the original TSW-119-14-F-D reaches end-of-life, experiences supply constraints, or when design requirements necessitate alternative contact configurations or position counts while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the TSW-119-14-F-D is based on the following critical parameters that must align for functional compatibility:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) - determines PCB footprint compatibility
• Number of Rows: 2 - establishes physical layout and spacing
• Row Spacing - Mating: 0.100" (2.54mm) - defines center-to-center row distance
• Contact Type: Male Pin - specifies mating interface
• Mounting Type: Through Hole - confirms PCB assembly method
• Termination: Solder - establishes connection method

Secondary Compatibility Considerations:

• Connector Type: Header or Header Breakaway variants
• Shrouding: Unshrouded configuration
• Contact Finish - Mating: Gold or equivalent conductive finish
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Must encompass or match -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0 compliance

The substitute part 4-103322-0 (TE Connectivity AMP Connectors) shares the fundamental pitch, row configuration, and mounting characteristics. However, this part carries Obsolete product status and differs in position count (80 vs. 38), contact finish composition (Tin-Lead vs. Gold), and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

TSW-119-14-F-D (Primary Selection): The TSW-119-14-F-D maintains Active product status with confirmed ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs. The gold-plated mating contacts provide superior corrosion resistance and contact reliability compared to tin-lead finishes. The operating temperature range of -55°C ~ 125°C accommodates extended industrial and aerospace applications. Phosphor bronze contact material delivers consistent performance across thermal cycling. This part is the recommended selection for new designs and applications requiring current compliance certifications.

4-103322-0 (Conditional Substitute): The TE Connectivity 4-103322-0 carries Obsolete product status, indicating discontinued manufacturing and limited future availability. This part is suitable only for legacy system maintenance or replacement scenarios where the original TSW-119-14-F-D cannot be sourced. The 80-position configuration requires PCB redesign if the original 38-position layout is maintained. The tin-lead contact finish and lower maximum operating temperature (105°C vs. 125°C) present constraints for high-temperature applications. The Obsolete designation precludes this part from new design consideration.

Compliance Considerations: The TSW-119-14-F-D's ROHS3 compliance status ensures compatibility with current regulatory requirements across EU, China, and other jurisdictions implementing RoHS directives. The 4-103322-0's "Not applicable" RoHS status reflects its obsolete classification and historical manufacturing period predating current compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the 4-103322-0 directly replace the TSW-119-14-F-D in existing PCB designs?

A: Direct replacement is not possible without PCB redesign. The 4-103322-0 provides 80 positions versus the TSW-119-14-F-D's 38 positions. While both maintain 0.100" (2.54mm) pitch and 2-row configuration, the increased position count requires modified PCB footprints and connector placement. Additionally, the Obsolete product status of the 4-103322-0 makes it unsuitable for new applications.

Q: What are the key electrical differences between these connectors?

A: Both connectors share identical pitch (0.100"), row spacing (0.100"), and mounting characteristics. The primary electrical difference lies in contact finish: the TSW-119-14-F-D uses gold plating (3.00µin thickness) for superior conductivity and corrosion resistance, while the 4-103322-0 uses tin-lead plating (100.0µin thickness). Contact material differs as well: phosphor bronze versus copper alloy. These differences affect long-term reliability in corrosive environments and thermal cycling applications.

Q: Are there temperature-related constraints when considering substitution?

A: Yes. The TSW-119-14-F-D operates across -55°C to 125°C, while the 4-103322-0 operates across -65°C to 105°C. Applications requiring sustained operation above 105°C cannot use the 4-103322-0. The TSW-119-14-F-D's extended upper temperature limit makes it suitable for automotive, industrial, and aerospace environments with elevated thermal requirements.

Q: What does the Obsolete product status mean for the 4-103322-0?

A: Obsolete status indicates that TE Connectivity has discontinued manufacturing of the 4-103322-0. Existing inventory may be available through authorized distributors, but no new production is scheduled. This status makes the part unsuitable for new product designs requiring multi-year component availability and supply chain stability. The part is appropriate only for legacy system repairs where original specifications must be maintained.

Q: How do the insulation materials compare?

A: The TSW-119-14-F-D specifies polybutylene terephthalate (PBT), a high-performance thermoplastic with excellent dimensional stability and chemical resistance. The 4-103322-0 specifies generic thermoplastic material without specific polymer identification. PBT provides superior performance in moisture absorption resistance and maintains mechanical properties across the extended temperature range. Both achieve UL94 V-0 flammability rating.

Q: Can position count differences affect circuit design?

A: Yes. The TSW-119-14-F-D's 38-position configuration is fixed by PCB layout and connector footprint. The 4-103322-0's 80-position design requires either unused positions (wasting board space and cost) or complete PCB redesign to utilize the additional positions. Position count mismatch necessitates careful evaluation of actual circuit requirements before substitution.

Q: What compliance certifications should be verified for new designs?

A: The TSW-119-14-F-D's ROHS3 compliance ensures compatibility with current regulatory frameworks in the EU, China, and other regions. The part's UL94 V-0 flammability rating meets safety standards for consumer and industrial applications. For new designs, the TSW-119-14-F-D is the appropriate selection. The 4-103322-0's "Not applicable" RoHS status reflects its obsolete classification and historical manufacturing period, making it unsuitable for applications requiring current compliance documentation.
