50 positions in 2-row configuration
0.100" (2.54mm) mating pitch and row spacing
Male pin contact type
Through-hole mounting
Unshrouded design
Square contact shape
Push-pull fastening type
UL94 V-0 flammability rating
MSL 1 moisture sensitivity

Secondary Compatibility Factors:

Contact finish material (gold or tin acceptable for mating surfaces)
Overall contact length tolerance (11.10mm to 12.12mm range)
Insulation height (2.29mm to 2.79mm range)
Current rating (2A to 3A per contact)
Operating temperature range (-65°C minimum to 105°C minimum)

Substitute parts are grouped based on adherence to these parameters. Parts with matching pitch, position count, row configuration, and mounting type are considered functionally equivalent. Variations in contact finish, insulation material, and contact geometry are acceptable provided they maintain electrical and mechanical compatibility within the specified ranges.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The following parts provide direct functional equivalence to the TE Connectivity 1-104350-8:

Molex 0702871023 and Molex 0702871219 (C-Grid 70287 Series) are active components with matching 50-position, 2-row, 0.100" pitch configuration. Both feature kinked pin solder termination and square contact geometry. The 0702871219 variant includes gold mating contact finish matching the original part. Both are ROHS3 compliant and maintain UL94 V-0 flammability rating.

Amphenol ICC 54102-S0625LF (BERGSTIK® Series) provides equivalent electrical and mechanical specifications with gold-plated mating contacts, 3A current rating, and -65°C to 125°C operating temperature range. This part is RoHS compliant and maintains all critical dimensional parameters.

Samtec TD-125-G-A-1 and TD-125-T-A-1 (TD Series) offer active alternatives with 50-position, 2-row configuration and 0.100" pitch. The TD-125-G-A-1 features gold contact finish; the TD-125-T-A-1 provides tin finish. Both are ROHS3 compliant and through-hole mounted.

Secondary Substitutes (Acceptable with Design Verification):

Molex 0010897501 (C-Grid 70280 Series) matches core specifications but features tin mating contact finish and solder-only termination. Operating temperature range is not specified; design verification is required for temperature-critical applications.

Preci-Dip 450-80-250-00-001101 (450 Series) provides equivalent 50-position, 2-row configuration with extended operating temperature range (-55°C to 125°C) and higher voltage rating (150VDC). Contact shape is circular rather than square; mechanical compatibility with existing mating connectors must be confirmed.

3M 961250-6404-AR (961 Series) offers 50-position, 2-row configuration with gold mating finish but reduced current rating (2A versus 3A). Operating temperature range is -25°C to 105°C, which may limit use in low-temperature applications.

Amphenol ICC 94654-150HLF (BERGSTIK® II Series) features kinked pin termination and gold mating contacts but has reduced overall contact length (10.54mm) compared to the original specification (11.18mm). This dimensional difference requires verification for PCB stack-up compatibility.

Compliance Considerations:

The original TE Connectivity 1-104350-8 is RoHS non-compliant. All recommended active substitutes are RoHS compliant or ROHS3 compliant, supporting transition to current regulatory requirements. All substitute parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 1-104350-8?

A: The following parameters must match or be compatible: 50 positions in 2-row configuration, 0.100" (2.54mm) mating pitch and row spacing, male pin contact type, through-hole mounting, unshrouded design, square contact shape, and push-pull fastening. Operating temperature range must support the application minimum of -65°C, and current rating must meet or exceed 3A per contact.

Q: Can I use a substitute part with a different contact finish (tin instead of gold)?

A: Yes, provided the mating connector is compatible with the alternate finish. Tin-plated contacts (Molex 0010897501, 0702871023) are acceptable substitutes for gold-plated contacts in applications where the mating connector accepts tin finish. However, if the existing mating connector requires gold plating, gold-finished substitutes (Molex 0702871219, Amphenol ICC 54102-S0625LF, 3M 961250-6404-AR, Samtec TD-125-G-A-1) must be selected.

Q: What is the difference between the Molex C-Grid 70280 and C-Grid 70287 series?

A: Both series provide 50-position, 2-row headers with 0.100" pitch. The primary difference is termination type: C-Grid 70280 (part 0010897501) uses solder-only termination, while C-Grid 70287 (parts 0702871023 and 0702871219) uses kinked pin solder termination. The kinked pin design provides improved mechanical retention during soldering.

Q: Are Samtec TD series connectors fully compatible with the original TE part?

A: Samtec TD-125-G-A-1 and TD-125-T-A-1 match the core specifications (50 positions, 2 rows, 0.100" pitch, through-hole mounting, square contacts, push-pull fastening). However, detailed dimensional specifications for insulation height and contact length are not provided in the available data. Physical verification is recommended before production implementation.

Q: Why does the Preci-Dip 450 series have circular contacts instead of square?

A: The Preci-Dip 450 series uses circular contact geometry, which differs from the square contact design of the original TE part. While the 50-position, 2-row, 0.100" pitch configuration is identical, the circular contact shape may affect mating with existing connectors designed for square contacts. Mechanical compatibility must be confirmed with the mating connector specification.

Q: What is the significance of the current rating difference between the 3M 961250-6404-AR (2A) and the original part (3A)?

A: The 3M part is rated for 2A per contact, while the original TE part is rated for 3A per contact. If the application requires 3A per contact, the 3M part is not suitable. For applications requiring 2A or less, the 3M part is acceptable. Current rating must be verified against actual application requirements.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are either RoHS compliant or ROHS3 compliant. The original TE Connectivity 1-104350-8 is RoHS non-compliant. Substitution with any of the listed active parts supports compliance with current RoHS regulations.

Q: What packaging options are available for these substitute parts?

A: Packaging varies by manufacturer and part number. Molex parts are supplied in bulk packaging. Amphenol ICC parts are supplied in bag packaging. Preci-Dip parts are supplied in bulk packaging. Samtec parts are supplied in tube packaging. Packaging selection should be based on assembly process requirements and inventory management practices.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: Yes, provided each part meets the application requirements independently. However, using parts from a single manufacturer within an assembly simplifies supply chain management and reduces the risk of subtle compatibility issues. If multiple manufacturers are used, each part must be individually verified for compatibility with its mating connector.

Q: What is the operating temperature range consideration for substitute selection?

A: The original TE part operates from -65°C to 105°C. Substitute parts with equal or wider temperature ranges are preferred. The Preci-Dip 450 series (-55°C to 125°C) and Amphenol ICC 54102-S0625LF (-65°C to 125°C) offer extended ranges. The 3M 961250-6404-AR (-25°C to 105°C) has a narrower low-temperature range and is unsuitable for applications requiring -65°C operation.
