TSW-108-08-L-S-NA Equivalent & Substitute Parts

Part Overview

The TSW-108-08-L-S-NA is an 8-position rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This unshrouded header features a 0.100" (2.54mm) pitch with male pin contacts, solder termination, and push-pull fastening. The part is Active status and ROHS3 compliant, making it suitable for standard electronic assembly applications requiring reliable interconnection in compact form factors.

Substitute parts are necessary when addressing inventory constraints, lead time requirements, or when design specifications allow for alternative insulation materials or contact configurations within the same electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-108-08-L-S-NA is determined by the following critical parameters:

• Connector Type, Contact Type, Number of Positions, Pitch: All substitute parts must maintain identical values (Header, Male Pin, 8 positions, 0.100" pitch)
• Mounting Type, Termination, Fastening Type: All substitute parts must match (Through Hole Right Angle, Solder, Push-Pull)
• Contact Finish - Mating, Contact Material: All substitute parts must maintain gold-plated mating surfaces with phosphor bronze material
• Operating Temperature Range: All substitute parts must support -55°C ~ 125°C
• Material Flammability Rating: All substitute parts must meet UL94 V-0
• RoHS Compliance: All substitute parts must be ROHS3 compliant

Variations permitted in substitute parts include insulation material composition (PBT versus LCP) and insulation height within specified tolerances, provided all other electrical and mechanical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The TSW-108-08-L-S-RA provides direct substitution with identical electrical and mechanical specifications, differing only in part number designation within the same TSW series.

The HTSW-108-08-L-S-RA and HTSW-108-08-LM-S-RA variants utilize Liquid Crystal Polymer (LCP) insulation material in place of PBT, with a corresponding increase in insulation height from 0.119" to 0.122". Both HTSW variants maintain all critical electrical parameters, contact specifications, and temperature ratings. The insulation material change from PBT to LCP provides enhanced dimensional stability and chemical resistance while maintaining UL94 V-0 flammability compliance.

Selection between PBT-based (TSW series) and LCP-based (HTSW series) variants depends on application-specific environmental and mechanical requirements. All parts are manufactured by Samtec Inc. and carry identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can TSW-108-08-L-S-NA be directly replaced with TSW-108-08-L-S-RA?

A: Yes. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, mounting orientation, termination method, contact materials, and operating temperature range. The parts are functionally equivalent.

Q: What is the difference between TSW and HTSW series headers?

A: The primary difference is insulation material composition. TSW series uses Polybutylene Terephthalate (PBT) with an insulation height of 0.119" (3.02mm), while HTSW series uses Liquid Crystal Polymer (LCP) with an insulation height of 0.122" (3.10mm). All other electrical and mechanical parameters remain identical. Both series maintain UL94 V-0 flammability rating and -55°C ~ 125°C operating temperature range.

Q: Are there compatibility concerns when substituting between PBT and LCP insulation materials?

A: The 0.003" (0.08mm) difference in insulation height between PBT and LCP variants must be evaluated against specific PCB layout and mating connector tolerances. Both materials maintain identical contact geometry, pitch, and electrical performance. Application-specific mechanical clearance requirements determine substitution feasibility.

Q: What does the "LM" designation in HTSW-108-08-LM-S-RA indicate?

A: The "LM" designation indicates a specific contact or configuration variant within the HTSW-108 base product family. The part maintains all critical specifications identical to HTSW-108-08-L-S-RA, including insulation material (LCP), dimensions, contact finish, and operating parameters.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TSW-108-08-L-S-NA, TSW-108-08-L-S-RA, HTSW-108-08-L-S-RA, and HTSW-108-08-LM-S-RA are all ROHS3 compliant. All parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code.

Q: What inventory considerations apply to these substitute parts?

A: Current inventory levels are: TSW-108-08-L-S-NA (768 pcs), TSW-108-08-L-S-RA (2073 pcs), HTSW-108-08-L-S-RA (706 pcs), and HTSW-108-08-LM-S-RA (686 pcs). All parts are listed as New Original In Stock from Samtec Inc.
