TSS-120-02-F-D Equivalent & Substitute Parts

Part Overview

The TSS-120-02-F-D is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 40-position, 2-row connector operates across the industrial temperature range of -55°C to 125°C and features shrouded 4-wall construction with push-pull fastening. The part is ROHS3 compliant and carries UL94 V-0 flammability certification. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in board-to-board or cable interconnect applications.

Substitute Part Grouping Explanation

The HTST-120-02-F-D qualifies as a substitute based on alignment of critical electrical and mechanical parameters. Both parts share identical specifications for connector type (header), contact type (male pin), position count (40), row configuration (2 rows), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting method (through hole), shrouding design (shrouded 4-wall), fastening mechanism (push-pull), contact material (phosphor bronze), mating contact finish (gold), and operating temperature range (-55°C to 125°C). Both parts maintain UL94 V-0 flammability certification and ROHS3 compliance.

Substitution is valid where the following parameters are equivalent:

• Mating pitch and row spacing
• Position count and row configuration
• Through-hole mounting compatibility
• Contact material and mating finish specifications
• Operating temperature range
• Regulatory compliance certifications

Parameter Comparison

Engineering Selection Recommendations

Both TSS-120-02-F-D and HTST-120-02-F-D are active products from Samtec Inc. with identical electrical and mechanical specifications for mating interface, contact configuration, and operating conditions. Selection between these parts should be based on application-specific requirements regarding insulation material properties. The TSS series uses polybutylene terephthalate (PBT) insulation, while the HTST series employs liquid crystal polymer (LCP) insulation. Both materials satisfy UL94 V-0 flammability requirements and ROHS3 compliance. The HTST-120-02-F-D provides current rating specification of 3.4A per contact, whereas the TSS-120-02-F-D does not specify this parameter in the provided data. Both parts are suitable for board-to-board or cable interconnect applications with identical through-hole mounting and push-pull fastening characteristics.

Frequently Asked Questions (FAQ)

Q: Can HTST-120-02-F-D directly replace TSS-120-02-F-D in existing designs?

A: Yes, for applications where the mating interface, position count, pitch, row spacing, mounting method, and operating temperature range are the primary design constraints. Both parts share identical specifications for these parameters. Insulation material differences (PBT versus LCP) may affect thermal or chemical resistance in specific environments; review application requirements accordingly.

Q: What are the key differences between these substitute parts?

A: The primary differences are insulation material composition (PBT in TSS-120-02-F-D versus LCP in HTST-120-02-F-D) and moisture sensitivity level classification. The HTST-120-02-F-D specifies 3.4A per contact current rating, while the TSS-120-02-F-D does not provide this specification in available data. Both parts maintain identical electrical and mechanical interface specifications.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both connectors share identical mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), contact length specifications, and through-hole mounting configuration. PCB footprints designed for either part are interchangeable.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both TSS-120-02-F-D and HTST-120-02-F-D are ROHS3 compliant, carry UL94 V-0 flammability certification, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C, supporting industrial and extended temperature applications.
