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

Part Overview

The TSW-111-14-S-S is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 11-position, single-row header operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts for reliable solder termination. The connector maintains an active product status with full inventory availability. Substitute parts become necessary when addressing obsolescence concerns, sourcing constraints, or specific application requirements that demand alternative connector configurations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical and electrical compatibility
• Contact Type: Male Pin — determines mating interface requirements
• Mounting Type: Through Hole — establishes PCB assembly compatibility
• Termination: Solder — defines connection method to printed circuit board
• Contact Finish - Mating: Gold — ensures signal integrity and corrosion resistance
• Insulation Material: PBT or equivalent thermoplastic — maintains structural and thermal properties
• Operating Temperature Range: Must encompass or match the -55°C ~ 125°C specification
• Material Flammability Rating: UL94 V-0 — required for safety compliance

The substitute part 4-102972-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) shares the same 0.100" pitch, male pin contact type, through-hole mounting, solder termination, gold mating finish, and UL94 V-0 flammability rating. However, this part is listed as obsolete and features a 40-position configuration compared to the 11-position main part. The substitute maintains core electrical and mechanical compatibility parameters but differs in position count and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TSW-111-14-S-S remains the primary selection for new designs due to its active product status and ROHS3 compliance. This ensures long-term availability and regulatory alignment for modern applications.

The substitute part 4-102972-0 presents compatibility considerations that require careful evaluation:

Advantages of the substitute:

• Identical 0.100" (2.54mm) pitch enables direct mechanical interface compatibility
• Matching male pin contact type and through-hole solder termination
• Gold-plated mating contacts and UL94 V-0 flammability rating maintain electrical and safety standards
• Breakaway feature provides design flexibility for modular applications
• Extended lower operating temperature range (-65°C vs. -55°C) supports colder environments

Limitations of the substitute:

• Obsolete product status restricts future availability and sourcing reliability
• 40-position configuration requires design modification for 11-position applications
• Lower mating contact finish thickness (15.0µin vs. 30.0µin) may affect long-term contact reliability
• Tin-Lead post finish conflicts with RoHS3 compliance requirements
• Operating temperature upper limit (105°C vs. 125°C) restricts high-temperature applications
• Not applicable RoHS status indicates non-compliance with modern regulatory standards

Substitution with 4-102972-0 is appropriate only when the 40-position breakaway configuration aligns with application requirements and when RoHS3 compliance is not mandated. For applications requiring the 11-position configuration, active product status, or RoHS3 compliance, the TSW-111-14-S-S is the required selection.

Frequently Asked Questions (FAQ)

Q: Can the 4-102972-0 substitute directly replace the TSW-111-14-S-S in existing designs?

A: Direct replacement is not recommended. While both connectors share the same 0.100" (2.54mm) pitch and male pin contact type, the substitute features a 40-position configuration compared to the main part's 11-position design. PCB layout and connector footprint modifications would be required. Additionally, the substitute's obsolete status and non-RoHS3 compliance present long-term sourcing and regulatory risks.

Q: What are the key compatibility parameters between these connectors?

A: Compatibility is established through matching pitch (0.100"), contact type (male pin), mounting method (through-hole), termination (solder), and mating contact finish (gold). Both connectors maintain UL94 V-0 flammability ratings and operate within overlapping temperature ranges. However, the position count difference (11 vs. 40) is a critical design parameter that prevents direct substitution without layout modification.

Q: Does the substitute part meet RoHS3 requirements?

A: No. The 4-102972-0 has a "Not applicable" RoHS status and features tin-lead post finish, which does not comply with RoHS3 standards. The TSW-111-14-S-S is ROHS3 compliant and is the appropriate selection for applications requiring regulatory compliance.

Q: What is the significance of the contact finish thickness difference?

A: The main part features 30.0µin (0.76µm) gold plating on mating contacts, while the substitute provides 15.0µin (0.38µm). Thicker plating generally provides enhanced durability and corrosion resistance over extended operational life and repeated mating cycles. For applications with high mating cycle requirements, the main part's thicker finish is preferable.

Q: Can the substitute be used in high-temperature applications?

A: The substitute's operating temperature range (-65°C ~ 105°C) has a lower upper limit than the main part (-55°C ~ 125°C). Applications requiring sustained operation above 105°C must use the TSW-111-14-S-S to ensure reliable performance within specified thermal parameters.

Q: Why is the substitute listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for the 4-102972-0. This restricts future availability, extends lead times, and may result in higher costs. For new designs and long-term production requirements, the active TSW-111-14-S-S is the appropriate selection.
