Engineering Selection Recommendations

77313-170-26LF is the primary substitute for the obsolete 77313-170-26. Both parts are manufactured by Amphenol ICC within the BERGSTIK® series and share identical electrical and mechanical specifications. The 77313-170-26LF carries active product status and RoHS Compliant certification, addressing regulatory compliance requirements for new designs and production runs. This part is available in bulk packaging with 874 units in stock.

TD-113-T-B (Samtec Inc.) serves as a cross-manufacturer alternative when Amphenol ICC parts are unavailable. This connector maintains the same 26-position, 2-row configuration at 0.100" pitch and through-hole mounting. The primary distinction is the contact type: TD-113-T-B uses solder cup termination rather than male pins, and mating contact finish is tin instead of gold. This part is ROHS3 Compliant and currently active with 1149 units in stock. Selection of this alternative requires verification that solder cup termination is compatible with the mating connector interface.

Frequently Asked Questions (FAQ)

Q: Can 77313-170-26LF be used as a direct replacement for 77313-170-26?

A: Yes. Both parts are manufactured by Amphenol ICC with identical electrical and mechanical specifications. The primary difference is product status: 77313-170-26 is obsolete while 77313-170-26LF is active. The 77313-170-26LF also meets RoHS Compliance requirements.

Q: What is the key difference between 77313-170-26LF and TD-113-T-B?

A: Both maintain the same 26-position, 2-row configuration at 0.100" pitch. The 77313-170-26LF uses male pin contacts with gold mating finish, while TD-113-T-B uses solder cup contacts with tin finish. Contact type compatibility with the mating connector must be verified before selection.

Q: Are there packaging differences between the substitute parts?

A: 77313-170-26LF is supplied in bulk packaging. TD-113-T-B is also supplied in bulk packaging. Both are available in quantities suitable for production applications.

Q: Does the change from gold to tin contact finish affect electrical performance?

A: Contact finish selection is determined by application requirements and mating connector specifications. Both gold and tin finishes provide adequate electrical conductivity for standard applications. Verification against mating connector requirements is necessary when selecting TD-113-T-B.

Q: Are both substitute parts RoHS compliant?

A: Yes. 77313-170-26LF is RoHS Compliant. TD-113-T-B is ROHS3 Compliant. The original 77313-170-26 is RoHS non-compliant.
