Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole
• Termination: Solder
• Contact Shape: Square
• Number of Rows: Single row configuration

Secondary Compatibility Criteria:

• Number of Positions: The substitute part 4-103321-0 contains 40 positions versus 19 positions in the main part. This difference permits substitution only when the application allows use of a longer header strip that can be mechanically separated or when the additional positions are not populated on the PCB.
• Contact Finish: Variations in mating contact finish (gold versus tin-lead) and post finish are acceptable provided the electrical interface requirements are met.
• Insulation Material: Both PBT and Thermoplastic materials satisfy UL94 V-0 flammability requirements.
• Operating Temperature: The substitute part operates at -65°C ~ 105°C, which is narrower than the main part's -55°C ~ 125°C range. Substitution is valid only when application temperatures remain within -65°C ~ 105°C.

Non-Substitutable Parameters:

• Contact Length - Mating and Overall Contact Length must remain within acceptable tolerance ranges for proper mating with corresponding receptacles.

Engineering Selection Recommendations

Primary Selection: TSW-119-14-F-S

The TSW-119-14-F-S remains the preferred component selection based on the following factors:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current regulatory requirements for new designs
• Operating temperature range of -55°C ~ 125°C accommodates extended environmental specifications
• Gold-plated mating contacts provide superior corrosion resistance and contact reliability
• Exact 19-position configuration matches typical application requirements without excess material

Substitute Selection: 4-103321-0

The TE Connectivity AMP Connectors part 4-103321-0 serves as an alternative only under specific conditions:

• Substitute is classified as Obsolete, indicating discontinued production status
• Narrower operating temperature range (-65°C ~ 105°C) restricts use to applications within this specification
• 40-position configuration requires mechanical separation or acceptance of unpopulated positions
• Tin-Lead contact finish is subject to RoHS restrictions in new designs; Not applicable RoHS status indicates this part predates current compliance requirements
• Lower insulation height (0.090" versus 0.100") may affect PCB layout compatibility
• Longer post length (0.125" versus 0.110") requires verification of solder joint clearance on PCB

Substitution of 4-103321-0 is acceptable only when all of the following conditions are met:

• Application operating temperature remains within -65°C ~ 105°C
• PCB design accommodates 40-position header or allows mechanical separation to 19 positions
• Tin-Lead contact finish meets application requirements or environmental restrictions do not apply
• Insulation height and post length variations are compatible with PCB layout and mating receptacle specifications
• Supply of TSW-119-14-F-S is unavailable and project timeline permits use of obsolete inventory

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0 substitute directly for the TSW-119-14-F-S without PCB modification?

A: Direct substitution without PCB modification is not recommended. The 4-103321-0 contains 40 positions versus 19 positions in the TSW-119-14-F-S. The substitute part features a breakaway design, allowing mechanical separation, but this requires manual processing. Additionally, the lower insulation height (0.090" versus 0.100") and longer post length (0.125" versus 0.110") may affect PCB layout compatibility. Verify mating receptacle clearance and solder joint spacing before substitution.

Q: What is the significance of the contact finish difference between gold and tin-lead?

A: The TSW-119-14-F-S uses gold-plated mating contacts, which provide superior corrosion resistance and lower contact resistance over extended service life. The 4-103321-0 uses tin-lead finish, which is acceptable for general applications but offers less corrosion protection. Gold plating is preferred for high-reliability applications, aerospace, and environments with corrosive atmospheres. Tin-lead finish is suitable for standard industrial and consumer applications with controlled environmental conditions.

Q: Why is the operating temperature range important for substitution?

A: The TSW-119-14-F-S operates from -55°C to 125°C, while the 4-103321-0 operates from -65°C to 105°C. The substitute part has a narrower upper temperature limit. If your application requires operation above 105°C, the substitute is not suitable. Conversely, if your application operates only within -65°C to 105°C, the substitute is acceptable from a thermal perspective. Always verify application temperature requirements before selecting a substitute component.

Q: What does "Obsolete" product status mean for the 4-103321-0?

A: Obsolete status indicates that TE Connectivity has discontinued production of the 4-103321-0. While existing inventory may be available from distributors, no new production runs are scheduled. This creates long-term supply risk and potential price volatility. The TSW-119-14-F-S, with Active status, is the recommended choice for new designs to ensure sustained availability and stable pricing throughout the product lifecycle.

Q: Are there any RoHS compliance concerns with substitution?

A: The TSW-119-14-F-S is ROHS3 compliant, meeting current regulatory requirements. The 4-103321-0 shows "Not applicable" RoHS status, indicating it was manufactured before RoHS regulations took effect or is not subject to these requirements. For new designs destined for markets with RoHS mandates (EU, China, and others), the TSW-119-14-F-S is the compliant choice. Use of the 4-103321-0 may violate regulatory requirements in certain jurisdictions.

Q: Can the 40-position 4-103321-0 be mechanically separated to create a 19-position header?

A: The 4-103321-0 features a breakaway design, which allows mechanical separation of individual positions. However, this requires manual processing and introduces labor costs and potential quality risks. Separation must be performed carefully to avoid damaging the insulation material or contact pins. This approach is suitable only for low-volume applications or emergency situations where the TSW-119-14-F-S is unavailable. For production quantities, use the exact 19-position TSW-119-14-F-S.

Q: What is the impact of the longer post length on PCB assembly?

A: The 4-103321-0 has a post length of 0.125" compared to 0.110" for the TSW-119-14-F-S. The longer post extends further through the PCB, which may affect solder joint formation and clearance to components on the opposite side of the board. Verify that PCB thickness and component placement accommodate the longer post. Excessive post length can create solder bridges or interfere with adjacent components. Consult PCB layout guidelines and perform clearance verification before substitution.

Q: Is the contact material difference between Phosphor Bronze and Copper Alloy significant?

A: Both Phosphor Bronze (TSW-119-14-F-S) and Copper Alloy (4-103321-0) are suitable contact materials for 0.100" pitch headers. Phosphor Bronze offers slightly better spring properties and fatigue resistance, making it preferred for high-cycle mating applications. Copper Alloy is adequate for standard applications with moderate mating cycles. For applications requiring frequent connector mating and unmating, the Phosphor Bronze contacts of the TSW-119-14-F-S are the better choice.

Q: What inventory considerations should guide substitution decisions?

A: The TSW-119-14-F-S has 777 units in stock, indicating strong availability. The 4-103321-0 has 980 units available but is classified as Obsolete, meaning inventory is finite and will not be replenished. For new designs or long-term production, prioritize the TSW-119-14-F-S to ensure sustained supply. Reserve the 4-103321-0 for legacy product support or emergency situations where the primary component is temporarily unavailable.
