TSW-104-08-F-S-LL Equivalent & Substitute Parts

Part Overview

The TSW-104-08-F-S-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This vertical header features 4 positions with 0.100" (2.54mm) pitch spacing and is classified as an unshrouded, board-to-board or cable connector. The part maintains active product status and is RoHS3 compliant with UL94 V-0 flammability rating. Substitute parts are identified to address inventory availability, extended lead times, or specific application requirements while maintaining electrical and mechanical compatibility within defined parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-104-08-F-S-LL is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Contact Type: Male Pin — electrical interface requirement
• Mounting Type: Through Hole — assembly process compatibility
• Insulation Material: Polybutylene Terephthalate (PBT) — mechanical and thermal stability
• Contact Material: Phosphor Bronze — electrical conductivity and durability
• Contact Finish - Mating: Gold — corrosion resistance and signal integrity
• Operating Temperature Range: minimum -55°C, maximum 125°C — thermal envelope
• Material Flammability Rating: UL94 V-0 — safety compliance
• RoHS Status: ROHS3 Compliant — regulatory requirement

The substitute part PBC04DABN shares these core parameters but differs in position count (8 vs. 4) and row configuration (2 rows vs. 1 row). This part is suitable for applications where the increased position capacity and dual-row layout do not conflict with PCB design constraints and where the connector footprint can accommodate the larger form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-104-08-F-S-LL and PBC04DABN maintain active product status and meet RoHS3 compliance requirements. Selection between these parts is determined by application-specific position and row requirements rather than compliance or reliability factors.

The TSW-104-08-F-S-LL is the primary selection for applications requiring exactly 4 positions in a single-row configuration. The PBC04DABN serves as a substitute only when the application design accommodates 8 positions arranged in 2 rows and when the increased overall contact length (0.560" vs. 0.530") does not create clearance conflicts on the PCB or in the assembly.

Both parts operate within overlapping temperature ranges, with PBC04DABN offering extended low-temperature capability (-65°C vs. -55°C). Both employ identical contact materials, finishes, and insulation specifications, ensuring equivalent electrical performance within their respective position configurations.

Frequently Asked Questions (FAQ)

Q: Can PBC04DABN be used as a direct replacement for TSW-104-08-F-S-LL?

A: PBC04DABN is not a direct pin-for-pin replacement due to differences in position count (8 vs. 4) and row configuration (2 vs. 1). Substitution is only valid when the PCB design and application requirements accommodate the 8-position, 2-row layout and the increased overall contact length.

Q: Are the mating pitch specifications identical?

A: Yes. Both parts maintain 0.100" (2.54mm) pitch spacing, which is the primary parameter determining PCB footprint compatibility. The PBC04DABN adds a second row with identical 0.100" (2.54mm) row spacing.

Q: What is the difference in contact post length?

A: The TSW-104-08-F-S-LL has a contact post length of 0.200" (5.08mm), while the PBC04DABN has 0.230" (5.84mm). This difference affects solder joint depth and PCB hole sizing. Verify PCB design specifications before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, UL94 V-0 rated, and classified under the same HTSUS code (8536.69.4040). Both carry EAR99 ECCN classification.

Q: What is the operating temperature difference?

A: The TSW-104-08-F-S-LL operates from -55°C to 125°C. The PBC04DABN operates from -65°C to 125°C, providing 10°C additional low-temperature capability. Both share the same maximum operating temperature.

Q: Are the contact materials and finishes equivalent?

A: Yes. Both parts use phosphor bronze contact material with gold mating finish and tin post finish, ensuring equivalent electrical conductivity and corrosion resistance.

Q: What does "Breakaway" mean for the PBC04DABN?

A: The breakaway feature allows individual connector positions to be separated from the main header assembly. This does not affect electrical or mechanical compatibility when used as a complete 8-position header.
