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

Part Overview

The TSW-120-14-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical header features 40 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is currently in active product status with 1038 units in stock. Substitute parts are identified when the main part becomes unavailable, discontinued, or when design requirements necessitate alternative connector configurations with compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-120-14-S-D is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Connector Type: Header with male pin contacts
• Mounting Type: Through Hole solder termination
• Contact Finish - Mating: Gold plating for signal integrity
• Insulation Material: PBT or equivalent thermoplastic
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Material Flammability Rating: UL94 V-0 compliance required

The substitute part 4-102977-0-10 (TE Connectivity AMP Connectors) shares the same mating pitch, connector type, mounting method, and contact finish specifications. However, this substitute has a reduced position count (20 positions versus 40 positions) and operates within a narrower temperature range (-65°C ~ 105°C). The substitute is classified as obsolete product status.

Parameter Comparison

Engineering Selection Recommendations

The TSW-120-14-S-D is the preferred component for new designs due to its active product status and ROHS3 compliance. The substitute part 4-102977-0-10 is classified as obsolete and does not meet RoHS compliance requirements, making it unsuitable for applications subject to environmental regulations or long-term supply chain requirements.

The substitute part differs in position count (20 versus 40), which restricts its application to designs requiring only 20 connection points. The operating temperature range of the substitute (-65°C ~ 105°C) does not extend to the upper temperature limit of the main part (125°C), limiting its use in high-temperature applications.

For applications requiring 40-position connectivity with extended temperature performance and regulatory compliance, the TSW-120-14-S-D remains the appropriate selection. The substitute should only be considered for legacy system maintenance where the original 20-position configuration is functionally equivalent and environmental compliance is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can the 4-102977-0-10 substitute be used in place of the TSW-120-14-S-D in new designs?

A: No. The substitute is obsolete and RoHS non-compliant. New designs must use the TSW-120-14-S-D or identify an alternative active-status connector with equivalent specifications.

Q: What is the primary difference between these two connectors?

A: The main difference is position count: the TSW-120-14-S-D provides 40 positions while the substitute provides 20 positions. The substitute also operates within a narrower temperature range (-65°C ~ 105°C versus -55°C ~ 125°C) and lacks RoHS3 compliance.

Q: Are the mating pitch and row spacing identical?

A: Yes. Both connectors use 0.100" (2.54mm) pitch for mating and row spacing, ensuring mechanical compatibility at the contact interface level.

Q: Does the substitute meet current environmental compliance standards?

A: No. The substitute is RoHS non-compliant, while the main part is ROHS3 compliant. Applications subject to environmental regulations must use the TSW-120-14-S-D.

Q: Can I use the substitute for applications operating above 105°C?

A: No. The substitute's maximum operating temperature is 105°C. Applications requiring operation up to 125°C must use the TSW-120-14-S-D.

Q: Are the contact materials equivalent?

A: No. The main part uses Phosphor Bronze contacts while the substitute uses Copper Alloy. Both materials support the specified gold mating finish and solder termination, but material composition differs.
