Engineering Selection Recommendations

Samtec Flex Stack Series (HTST-113-02-G-D, TST-113-02-G-D): These parts maintain full mechanical and electrical compatibility with the TSS-113-02-G-D. Both are ROHS3 compliant and active in production. HTST-113-02-G-D uses Liquid Crystal Polymer (LCP) insulation material and carries a 3.4A per contact current rating. TST-113-02-G-D uses glass-filled polybutylene terephthalate (PBT) insulation and also carries a 3.4A per contact current rating. Selection between these three Samtec parts depends on insulation material requirements and specific application thermal or mechanical constraints.

TE Connectivity AMP-Latch Series (103308-6, 103309-6, 5103308-6, 5103309-6): These parts provide functional equivalence but differ in compliance status and contact geometry. Parts 103308-6 and 103309-6 are RoHS non-compliant and packaged in bulk. Parts 5103308-6 and 5103309-6 are ROHS3 compliant and packaged in tubes. The primary distinction between 103308-6 and 103309-6 (and their 5103xxx counterparts) is contact finish thickness on the mating surface: 15.0µin (0.38µm) versus 30.0µin (0.76µm) respectively. Contact post finish differs between bulk packaging (Tin-Lead) and tube packaging (Tin). Operating temperature range is -65°C to 105°C, which is narrower than the Samtec parts. These parts are suitable for applications where RoHS compliance is not required or where the narrower temperature range is acceptable.

For applications requiring ROHS3 compliance and the full -55°C to 125°C operating range, Samtec Flex Stack series parts are the appropriate selection. For applications with RoHS compliance requirements and standard temperature ranges, TE Connectivity 5103308-6 or 5103309-6 are suitable alternatives.

Frequently Asked Questions (FAQ)

Q: Can TSS-113-02-G-D be directly replaced with TE Connectivity AMP-Latch parts?

A: Yes, mechanically and electrically. However, contact length differences exist: TSS-113-02-G-D has 0.250" mating contact length versus 0.240" for AMP-Latch parts. This 0.010" difference may affect mating force and contact engagement depth in applications with tight tolerance requirements. Verify PCB design accommodates the shorter contact length before substitution.

Q: What is the difference between 103308-6 and 103309-6?

A: Both are TE Connectivity AMP-Latch 26-position headers with identical mechanical specifications. The difference is contact finish thickness on the mating surface: 103308-6 has 15.0µin (0.38µm) gold or gold-palladium finish, while 103309-6 has 30.0µin (0.76µm). Thicker finish provides enhanced wear resistance and contact durability in high-cycle mating applications.

Q: What is the difference between bulk and tube packaging for TE Connectivity parts?

A: 103308-6 and 103309-6 are bulk packaged and RoHS non-compliant. 5103308-6 and 5103309-6 are tube packaged and ROHS3 compliant. Contact post finish also differs: bulk parts use Tin-Lead, while tube parts use Tin. Tube packaging is preferred for applications requiring RoHS compliance and lead-free soldering processes.

Q: Are Samtec HTST-113-02-G-D and TST-113-02-G-D interchangeable with TSS-113-02-G-D?

A: Yes. All three Samtec parts share identical connector type, position count, pitch, mounting type, and fastening mechanism. Primary differences are insulation material (HTST uses LCP, TST uses glass-filled PBT, TSS uses standard PBT) and current rating (HTST and TST are rated 3.4A per contact). All three are ROHS3 compliant and operate across -55°C to 125°C.

Q: Which substitute part has the highest current rating?

A: HTST-113-02-G-D and TST-113-02-G-D both carry 3.4A per contact current rating. TE Connectivity AMP-Latch parts carry 1A per contact. For high-current applications, Samtec Flex Stack series parts are required.

Q: Can I use TSS-113-02-G-D in applications requiring RoHS compliance?

A: Yes. TSS-113-02-G-D is ROHS3 compliant. All Samtec Flex Stack series parts (TSS, HTST, TST) are ROHS3 compliant. TE Connectivity 103308-6 and 103309-6 are RoHS non-compliant; use 5103308-6 or 5103309-6 for RoHS-compliant applications.

Q: What is the operating temperature difference between Samtec and TE Connectivity parts?

A: Samtec Flex Stack series (TSS, HTST, TST) operate across -55°C to 125°C. TE Connectivity AMP-Latch series operate across -65°C to 105°C. Samtec parts support higher maximum temperature; TE Connectivity parts support lower minimum temperature. Application thermal requirements determine which series is appropriate.
