TE Connectivity 1-104351-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-104351-6 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole connector features 34 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable applications. The connector utilizes male pins with gold-plated mating contacts and tin-lead plated posts for solder termination.

The 1-104351-6 is classified as obsolete product status. Equivalent and substitute parts are necessary to maintain design compatibility in applications where original stock is depleted or long-term availability cannot be assured. Active alternative connectors from Amphenol ICC (FCI) and Samtec Inc. provide functional equivalence while offering improved availability and compliance certifications.

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 1-104351-6 is classified as obsolete. All four substitute parts—67996-134HLF, 67996-234HLF, 67997-734HLF, and TSW-117-07-L-D—maintain active product status, ensuring continued availability and manufacturer support.

Compliance and Certification: The original 1-104351-6 is RoHS non-compliant. All substitute parts are RoHS compliant (either RoHS Compliant or ROHS3 Compliant), meeting current regulatory requirements for new designs and procurement in regulated markets.

Amphenol ICC (FCI) BERGSTIK® II Series Selection: The three Amphenol ICC parts (67996-134HLF, 67996-234HLF, 67997-734HLF) represent the most direct functional equivalents. These parts share identical connector geometry, pitch spacing, and contact configuration. The BERGSTIK® II series offers enhanced operating temperature ranges (-65°C to 125°C or -65°C to 130°C) compared to the original part (-65°C to 105°C).

67996-134HLF and 67996-234HLF differ only in contact finish thickness (30.0µin versus 15.0µin respectively). Both feature shorter post lengths (0.095") compared to the original.
67997-734HLF matches the original post length (0.120") and offers the highest operating temperature range (-65°C to 130°C).

Samtec Inc. TSW Series Selection: The TSW-117-07-L-D provides an alternative from a different manufacturer with equivalent electrical and mechanical specifications. This part features the lowest contact finish thickness (10.0µin) and operates across -55°C to 125°C. The TSW series uses polybutylene terephthalate (PBT) insulation material and achieves ROHS3 compliance.

Recommendation Logic: Selection between substitute parts depends on specific application requirements:

For applications requiring maximum post length retention, select 67997-734HLF.
For applications with extended high-temperature operation, select 67997-734HLF (-65°C to 130°C).
For applications prioritizing contact finish thickness matching the original specification (15.0µin), select 67996-234HLF.
For applications requiring alternative manufacturer sourcing, select TSW-117-07-L-D.

All four substitutes maintain mechanical and electrical compatibility with the original 1-104351-6 within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 67996-134HLF directly replace the TE Connectivity 1-104351-6?

A: Yes. The 67996-134HLF meets all mandatory matching parameters: 34 positions, 2 rows, 0.100" pitch, male pins, through-hole mounting, solder termination, square contacts, push-pull fastening, UL94 V-0 rating, and black insulation. The contact post length differs (0.095" versus 0.120"), which falls within allowable variation for board-to-board applications.

Q: What is the difference between 67996-134HLF and 67996-234HLF?

A: Both parts are functionally equivalent with identical geometry and electrical ratings. The primary difference is contact finish thickness on the mating surface: 67996-134HLF features 30.0µin (0.76µm) while 67996-234HLF features 15.0µin (0.38µm), matching the original 1-104351-6 specification.

Q: Why does 67997-734HLF have a different part number prefix?

A: The 67997 prefix indicates a different product line within the BERGSTIK® II series. The 67997-734HLF maintains identical connector specifications but offers extended operating temperature range (-65°C to 130°C) and matches the original post length (0.120").

Q: Is the Samtec TSW-117-07-L-D compatible with the same mating connectors?

A: Yes. The TSW-117-07-L-D maintains identical pitch spacing (0.100"), position count (34), row configuration (2 rows), and contact geometry (square male pins). It mates with standard 0.100" pitch receptacles designed for the original 1-104351-6.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: RoHS compliance is mandatory for products sold into European markets and many regulated industries. The original 1-104351-6 is RoHS non-compliant. All substitute parts are RoHS compliant, enabling use in new designs and procurement cycles subject to RoHS regulations.

Q: Does contact material difference (Copper Alloy versus Phosphor Bronze) affect compatibility?

A: No. Both materials provide equivalent electrical conductivity and mechanical performance for this connector class. Phosphor Bronze, used in all substitute parts, offers enhanced spring characteristics and durability compared to copper alloy.

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

A: Yes. All four substitute parts are mechanically and electrically interchangeable within the same assembly. However, for consistency in manufacturing and quality control, using a single part number across an assembly is recommended.

Q: What is the impact of insulation height variation (0.090" to 0.100")?

A: The insulation height variation is within acceptable tolerance for board-to-board connector applications. The 0.010" (0.254mm) difference does not affect mating performance or board layout compatibility.

Q: Which substitute part offers the best long-term availability?

A: All four substitute parts maintain active product status. Amphenol ICC and Samtec are established manufacturers with extensive distribution networks. For critical applications, verify current inventory levels with authorized distributors.

Q: Are there packaging differences between substitute parts?

A: The TE Connectivity 1-104351-6 packaging is not specified in available data. All substitute parts are supplied in bag packaging, which is standard for this connector category and does not affect functional performance.
