TSW-111-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-111-14-L-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This connector features 11 vertical positions with 0.100" (2.54mm) pitch spacing and is classified as an unshrouded, board-to-board or cable connector with solder termination. The part maintains active product status with full inventory availability.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements necessitate alternative connector configurations. The identification of equivalent components requires strict alignment of electrical and mechanical parameters to ensure functional compatibility within the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TSW-111-14-L-S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Connector Type: Header with male pin contact configuration
• Mounting Type: Through Hole solder termination
• Number of Rows: Single row configuration
• Shrouding: Unshrouded design

Secondary Compatibility Factors:

• Contact Finish - Mating: Gold plating for signal integrity
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Minimum -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0 compliance
• RoHS Compliance: ROHS3 Compliant status

The substitute part 4-103321-0 (TE Connectivity AMP Connectors) shares the fundamental pitch, connector type, mounting method, and row configuration. However, critical parameter deviations exist that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (TSW-111-14-L-S): The TSW-111-14-L-S maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). This part is recommended for new designs and applications requiring current regulatory compliance. The gold contact finish provides superior corrosion resistance and signal integrity for demanding applications.

Substitute Part (4-103321-0): The 4-103321-0 is classified as obsolete and carries "Not applicable" RoHS status, indicating it does not meet current regulatory requirements for new product designs. This part should be considered only for legacy system maintenance or applications where regulatory compliance is not a requirement.

Critical Deviations:

• Position count differs (11 vs. 40 positions) — the substitute provides additional positions that may require PCB redesign
• Contact finish differs (Gold vs. Tin-Lead) — affects signal integrity and environmental resistance
• Operating temperature upper limit differs (-55°C ~ 125°C vs. -65°C ~ 105°C) — the main part supports higher temperature operation
• Insulation height differs (0.100" vs. 0.090") — may impact mechanical fit in constrained spaces
• Product status and compliance diverge significantly

Frequently Asked Questions (FAQ)

Q: Can the 4-103321-0 be used as a direct replacement for the TSW-111-14-L-S?

A: Direct replacement is not recommended. While both connectors share 0.100" (2.54mm) pitch and through-hole solder termination, the substitute part has 40 positions compared to 11 positions in the main part. This requires PCB footprint modification. Additionally, the substitute is obsolete and does not meet ROHS3 compliance requirements.

Q: What are the key compatibility criteria for substituting this connector?

A: Substitutes must maintain 0.100" (2.54mm) mating pitch, single-row unshrouded header configuration, through-hole solder termination, and male pin contact type. Contact finish, operating temperature range, and regulatory compliance status must be evaluated against specific application requirements.

Q: Does the difference in contact finish affect electrical performance?

A: Contact finish differences (Gold vs. Tin-Lead) impact corrosion resistance, signal integrity, and long-term reliability. Gold plating provides superior performance in high-reliability and high-frequency applications. Tin-Lead finishes are suitable for standard industrial applications but may exhibit oxidation over extended storage or operation in corrosive environments.

Q: Why is the substitute part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The part may still be available through inventory channels but receives no further design support, process improvements, or regulatory updates. New designs should utilize active-status components.

Q: Are there compliance implications when using the substitute part?

A: Yes. The main part is ROHS3 compliant, while the substitute carries "Not applicable" RoHS status. Applications subject to RoHS regulations, EU directives, or customer compliance requirements must use the main part or an alternative that meets current standards.

Q: What is the significance of the insulation height difference?

A: Insulation height (0.100" vs. 0.090") affects the connector's profile and mechanical fit within the PCB assembly. In space-constrained applications, the lower insulation height of the substitute may provide advantages, but this requires verification against specific board layout requirements.
