All three substitute parts meet these criteria and are electrically and mechanically interchangeable with the TSW-104-08-SS-D.

Parameter Comparison

Engineering Selection Recommendations

TSW-104-08-SS-D (Primary Part) Select this part for new designs requiring standard PBT insulation material with black color coding. The part is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating. Current inventory of 743 units supports immediate procurement.

HMTSW-104-08-S-D-230 (Flex Stack Series Alternative) This substitute offers Liquid Crystal Polymer (LCP) insulation material with superior thermal and mechanical properties compared to PBT. The Flex Stack series designation indicates enhanced flexibility for applications requiring repeated mating cycles. The part specifies a 3A current rating and carries Not Applicable MSL status. Select this variant when LCP material properties are required or when the Flex Stack mechanical design benefits the application. Active production status with 709 units in stock.

TSW-104-08-S-D (Standard TSW Series) This part maintains identical electrical and mechanical specifications to the primary TSW-104-08-SS-D but carries a Discontinued at DiGi Electronics status. Highest inventory availability at 1092 units. Use only when existing stock must be consumed or when design documentation specifically references this part number. Not recommended for new designs due to discontinued status.

TSW-104-08-S-D-LC (TSW Series with LCP) This variant combines the standard TSW series designation with LCP insulation material, offering a middle-ground option between the primary PBT-based part and the Flex Stack alternative. Maintains active production status with 758 units in stock. Select when LCP material benefits are desired while maintaining standard TSW series compatibility.

Frequently Asked Questions (FAQ)

Q: Are all four parts electrically interchangeable? A: Yes. All parts share identical electrical specifications including contact material (Phosphor Bronze), contact finish (Gold mating surface, Tin post), pitch (0.100" / 2.54mm), number of positions (8), and operating temperature range (-55°C to 125°C).

Q: What is the difference between PBT and LCP insulation materials? A: Both materials meet UL94 V-0 flammability requirements and RoHS3 compliance. LCP (Liquid Crystal Polymer) offers superior thermal stability and mechanical strength compared to PBT (Polybutylene Terephthalate). LCP variants are HMTSW-104-08-S-D-230 and TSW-104-08-S-D-LC.

Q: Why does HMTSW-104-08-S-D-230 specify a 3A current rating while others do not? A: The current rating specification is provided only for the HMTSW-104-08-S-D-230 part. This does not indicate reduced current capability in other variants; it reflects available datasheet information. Consult manufacturer documentation for current handling specifications of TSW-104-08-SS-D, TSW-104-08-S-D, and TSW-104-08-S-D-LC.

Q: What does "Discontinued at DiGi Electronics" mean for TSW-104-08-S-D? A: This status indicates the part is no longer actively distributed through DiGi Electronics but may remain available through other channels or existing inventory. For new designs, select TSW-104-08-SS-D, HMTSW-104-08-S-D-230, or TSW-104-08-S-D-LC.

Q: Can I substitute TSW-104-08-SS-D with HMTSW-104-08-S-D-230 in existing designs? A: Yes, provided the design does not depend on specific PBT material properties or black insulation color. The HMTSW variant uses LCP insulation (natural color) and belongs to the Flex Stack series, which may offer improved performance in applications requiring repeated mating cycles.

Q: What is the significance of Moisture Sensitivity Level (MSL)? A: MSL 1 (Unlimited) indicates the part has no moisture sensitivity restrictions and requires no special handling or storage conditions. HMTSW-104-08-S-D-230 carries Not Applicable MSL status, indicating LCP material is inherently moisture-resistant and does not require MSL classification.

Q: Are all parts RoHS3 compliant? A: Yes. All four parts meet ROHS3 Compliant status, confirming compliance with Restriction of Hazardous Substances regulations.

Q: Which part should I select for a new design? A: For new designs, select either TSW-104-08-SS-D (standard PBT insulation, active production) or HMTSW-104-08-S-D-230 (LCP insulation with Flex Stack benefits, active production). Avoid TSW-104-08-S-D due to discontinued status. TSW-104-08-S-D-LC is also acceptable if LCP material is preferred within the standard TSW series.
