Engineering Selection Recommendations
Primary Substitutes (Active Product Status):
The following parts are recommended as primary substitutes due to active product status and full compliance with regulatory requirements:
Samtec TSW-104-08-F-S-RA - This connector maintains identical pitch, position count, and mounting configuration. It features gold-plated mating contacts with tin-plated posts, matching the original contact finish specification. The extended operating temperature range of -55°C to 125°C exceeds the original specification. ROHS3 compliance and REACH unaffected status align with current regulatory standards. Current inventory of 1,466 units supports production requirements.
Samtec HTSW-104-08-F-S-RA - This alternative provides equivalent electrical and mechanical characteristics with gold mating contacts and tin posts. The operating temperature range of -55°C to 125°C provides thermal margin beyond the original -65°C to 105°C specification. ROHS3 compliance and active product status ensure long-term availability. Inventory of 959 units is available.
Samtec HTSW-104-08-G-S-RA - This variant offers gold plating on both mating contacts and posts, providing enhanced corrosion resistance compared to the original tin-plated posts. Operating temperature range of -55°C to 125°C and ROHS3 compliance support modern design requirements. Inventory of 1,108 units is available.
Secondary Substitutes (Active Status with Parameter Variations):
Molex 0901210764 - This connector meets all critical electrical and mechanical parameters with active product status. The C-Grid III 90121 series provides equivalent functionality. Contact length variations (0.266" mating vs. 0.228" original) and insulation height differences (0.142" vs. 0.120" original) remain within acceptable connector interface tolerances. ROHS3 compliance and REACH unaffected status are confirmed. Inventory of 5,101 units provides substantial availability.
3M 929835-01-04-RK - This connector maintains core compatibility with 4-position, 2.54mm pitch configuration. The tin mating contact finish differs from the original gold specification, which may affect signal integrity in high-frequency applications. Operating temperature range of -40°C to 105°C provides reduced low-temperature margin compared to the original -65°C specification. Current rating of 2.5A is lower than the original 5A specification. Active product status and RoHS compliance are confirmed. Inventory of 1,427 units is available.
Tertiary Substitutes (Obsolete Status):
Amphenol ICC 75168-101-04LF - This BERGSTIK® series connector is classified as obsolete, limiting long-term availability. Contact length and insulation height parameters differ from the original specification. RoHS compliance is confirmed, but REACH status indicates affected substances. This part is suitable only for legacy system maintenance where new production is not anticipated.
Samtec TSW-104-08-F-S-RA-001 and TSW-104-08-F-S-RA-004 - These variants are loaded with only 3 positions instead of the full 4-position configuration of the original part. These are not suitable as direct substitutes for applications requiring all 4 positions.
Frequently Asked Questions (FAQ)
Q: Can the Molex 0901210764 be used as a direct replacement for the TE Connectivity 826652-4?
A: The Molex 0901210764 is electrically and mechanically compatible as a substitute. Both connectors share identical pitch (0.100"), position count (4), mounting type (through-hole right-angle), and termination method (solder). Contact length and insulation height variations fall within acceptable connector interface tolerances. The Molex part features active product status, ensuring ongoing availability, whereas the original TE part is obsolete. ROHS3 compliance is confirmed for both parts.
Q: What is the difference between the Samtec HTSW-104-08-F-S-RA and HTSW-104-08-G-S-RA?
A: Both Samtec HTSW variants maintain identical electrical and mechanical specifications with 4-position, 2.54mm pitch configuration and through-hole right-angle mounting. The primary difference is contact finish: the HTSW-104-08-F-S-RA features gold mating contacts with tin posts, matching the original TE part specification. The HTSW-104-08-G-S-RA features gold plating on both mating contacts and posts, providing enhanced corrosion resistance. Both operate across -55°C to 125°C and carry ROHS3 compliance.
Q: Why is the 3M 929835-01-04-RK listed as a secondary substitute despite lower current rating?
A: The 3M part maintains core connector compatibility with 4-position, 2.54mm pitch, through-hole right-angle mounting, and push-pull fastening. However, the 2.5A current rating is lower than the original 5A specification, and the operating temperature range of -40°C to 105°C provides reduced low-temperature margin. The tin mating contact finish differs from the original gold specification. This part is suitable only for applications where current requirements do not exceed 2.5A and low-temperature operation below -40°C is not required.
Q: Are there packaging differences between substitute parts?
A: Yes. The TE Connectivity 826652-4 packaging is not specified in available documentation. Molex 0901210764 is supplied in bulk packaging. Amphenol ICC 75168-101-04LF is supplied in bag packaging. Samtec parts (HTSW and TSW series) are supplied in bulk packaging. These packaging differences do not affect electrical or mechanical compatibility but may influence procurement and handling procedures.
Q: Can TSW-104-08-F-S-RA-001 or TSW-104-08-F-S-RA-004 substitute for the original 826652-4?
A: No. These Samtec variants are loaded with only 3 positions instead of the full 4-position configuration required by the original part. These parts are not suitable as direct substitutes for applications requiring all 4 connector positions.
Q: What is the significance of ROHS3 compliance versus RoHS compliance?
A: ROHS3 compliance indicates conformance to the most current Restriction of Hazardous Substances directive, including restrictions on phthalates and additional substances beyond earlier RoHS versions. Parts marked ROHS3 compliant (Samtec TSW and HTSW series, Molex 0901210764) meet the most stringent regulatory requirements. Parts marked only as RoHS compliant (Amphenol ICC 75168-101-04LF, 3M 929835-01-04-RK) meet earlier directive versions. For new designs, ROHS3 compliant parts are preferred.
Q: How do contact material differences affect substitution?
A: The original TE Connectivity 826652-4 uses brass contacts, while most substitute parts use phosphor bronze. Both materials provide adequate electrical conductivity and mechanical durability for 2.54mm pitch connectors. Phosphor bronze offers superior spring characteristics and wear resistance. Contact finish (gold or tin plating) is more significant than base material for signal integrity and corrosion resistance in typical applications.
Q: What is the impact of operating temperature range differences?
A: The original TE part operates from -65°C to 105°C. Samtec HTSW and TSW series parts operate from -55°C to 125°C, providing extended high-temperature capability but reduced low-temperature margin. The 3M 929835-01-04-RK operates from -40°C to 105°C, providing reduced low-temperature capability. For applications requiring operation below -55°C, the original TE part or equivalent parts with -65°C minimum rating must be specified. For applications requiring operation above 105°C, Samtec parts with 125°C maximum rating are required.
