TSW-120-14-L-S Equivalent & Substitute Parts

Part Overview

The TSW-120-14-L-S is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This unshrouded, single-row header accommodates 20 positions at 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts and tin-plated posts. The connector is suitable for board-to-board or cable interconnection in applications requiring solder termination with push-pull fastening. Identifying equivalent substitute parts is necessary when the primary part is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component standardization across product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-120-14-L-S is determined by strict alignment of the following critical parameters:

• Connector Type: Header with male pin contact type
• Pitch - Mating: 0.100" (2.54mm) spacing
• Mounting Type: Through hole solder termination
• Fastening Type: Push-pull mechanism
• Insulation Material: Polymer-based (PBT or LCP acceptable)
• Operating Temperature Range: Must encompass or exceed -55°C ~ 125°C
• Material Flammability: UL94 V-0 rating
• RoHS Compliance: ROHS3 or equivalent

The substitute part 9-146274-0 (TE Connectivity AMP Connectors AMPMODU Mod II series) meets these criteria with the following considerations: it maintains identical pitch, mounting type, termination method, and fastening type. Both parts feature unshrouded single-row headers with male pins, solder termination, and push-pull fastening. The substitute accommodates 40 positions versus 20 positions in the main part, which represents a functional superset. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-120-14-L-S and 9-146274-0 maintain active product status and comply with RoHS and REACH requirements. The primary distinction lies in position count: the TSW-120-14-L-S provides 20 positions, while the substitute 9-146274-0 provides 40 positions with breakaway capability. The substitute's breakaway feature permits field configuration to 20 positions, making it functionally compatible for applications requiring exactly 20 positions.

Operating temperature ranges differ: the TSW-120-14-L-S operates from -55°C to 125°C, while the 9-146274-0 operates from -65°C to 105°C. Applications requiring the full upper temperature range of 125°C should retain the primary part. Contact finish differs (gold versus tin on mating surfaces), which may affect corrosion resistance and contact reliability in specific environments. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level, ensuring equivalent environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the 9-146274-0 substitute for the TSW-120-14-L-S in all applications?

A: The 9-146274-0 is functionally compatible for applications requiring 20 or fewer positions due to its breakaway design. However, applications requiring operation above 105°C must use the TSW-120-14-L-S, which operates to 125°C. Contact finish differences (gold versus tin) may affect performance in corrosive environments.

Q: What is the significance of the breakaway feature on the 9-146274-0?

A: The breakaway feature permits field separation of the connector into smaller position counts. A 40-position header can be configured to 20 positions by breaking away the unused section, providing design flexibility without requiring a separate 20-position part.

Q: Are the insulation materials interchangeable?

A: Both PBT (TSW-120-14-L-S) and LCP (9-146274-0) are polymer-based insulation materials with UL94 V-0 flammability ratings. LCP offers superior dimensional stability and lower moisture absorption. Material selection depends on specific application requirements for thermal stability and moisture resistance.

Q: How do the contact finishes affect substitution?

A: The TSW-120-14-L-S features gold-plated mating contacts, while the 9-146274-0 features tin-plated mating contacts. Gold provides superior corrosion resistance and lower contact resistance over extended service life. Tin is suitable for standard industrial applications with moderate environmental exposure.

Q: Are both parts RoHS compliant?

A: Yes. The TSW-120-14-L-S is ROHS3 compliant, and the 9-146274-0 is RoHS compliant. Both meet current regulatory requirements for hazardous substance restrictions.
