68405-134HLF Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 68405-134HLF is a through-hole, right-angle rectangular connector header manufactured by Amphenol ICC (FCI) in the BERGSTIK® II series. This 34-position, 2-row connector with 0.100" (2.54mm) pitch is designed for board-to-board applications requiring solder termination and push-pull fastening. The part is currently active in production with 816 units in stock. Substitute parts are necessary when BERGSTIK® II series availability is limited, when alternative compliance certifications are required, or when design specifications allow for compatible connector geometries from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 68405-134HLF is determined by strict equivalence in the following critical parameters:

• Pitch and Position Count: All substitute parts maintain 0.100" (2.54mm) mating pitch with 34 positions in 2 rows
• Mounting Configuration: All substitutes are through-hole, right-angle headers suitable for board-to-board applications
• Termination Method: All substitutes use solder termination with push-pull fastening
• Electrical Performance: All substitutes meet or exceed the 5A current rating requirement
• Compliance: All substitutes maintain UL94 V-0 flammability rating and RoHS compliance

The three qualified substitutes represent different manufacturers (TE Connectivity, Sullins Connector Solutions, and Samtec) with variations in contact geometry, material composition, and operating temperature ranges. These variations are acceptable within the substitution criteria as they do not affect the fundamental board-to-board interconnection function.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 1-826634-7 (TE Connectivity AMPMODU Mod II)

The 1-826634-7 is the preferred substitute for the 68405-134HLF. Both parts maintain identical pitch, position count, and mounting configuration. The TE Connectivity part is currently active in production with 4200 units in stock, ensuring long-term availability. It carries ROHS3 compliance and meets the same UL94 V-0 flammability requirement. The 5A current rating matches the original specification. Minor geometric variations in contact length and insulation height are within acceptable tolerances for standard board-to-board interconnection applications.

Secondary Substitute: TSW-117-08-G-D-RA-018 (Samtec TSW Series)

The TSW-117-08-G-D-RA-018 maintains full electrical and mechanical compatibility with identical mating pitch and position count. This part is active in production with 662 units in stock and carries ROHS3 compliance with UL94 V-0 rating. The contact geometry closely matches the original part with identical mating contact length of 0.230" (5.84mm). Operating temperature range extends to 125°C, providing broader thermal performance. Note that 33 of 34 positions are loaded; verify application requirements before selection.

Tertiary Substitute: PEC17DGAN (Sullins Connector Solutions)

The PEC17DGAN maintains the required pitch and position count but is discontinued at DiGi Electronics. This part carries ROHS3 compliance and UL94 V-0 rating. The current rating is specified at 3A, which is lower than the original 5A specification. The extended operating temperature range of -65°C to 125°C may be beneficial for specific applications. This substitute should be selected only when the 3A current rating is acceptable and when inventory availability from alternative sources is confirmed.

Frequently Asked Questions (FAQ)

Q: Can the 1-826634-7 be used as a direct replacement for the 68405-134HLF?

A: Yes. Both parts share identical mating pitch (0.100"), position count (34), row configuration (2 rows), mounting type (through-hole right-angle), and termination method (solder). The 5A current rating and UL94 V-0 compliance are equivalent. Minor differences in contact geometry and insulation height do not affect functional compatibility in standard board-to-board applications.

Q: What is the difference between the breakaway and non-breakaway connector types?

A: The 1-826634-7 and PEC17DGAN are specified as "Header, Breakaway" connectors, meaning individual positions can be separated if required. The 68405-134HLF and TSW-117-08-G-D-RA-018 are standard headers without this feature. This difference does not affect compatibility when the full 34-position connector is used as designed.

Q: Why does the PEC17DGAN have a lower current rating of 3A?

A: The PEC17DGAN is rated for 3A per contact, compared to 5A for the original part. This specification difference reflects the contact material and geometry design of the Sullins connector. Applications requiring the full 5A rating should use the 68405-134HLF, 1-826634-7, or TSW-117-08-G-D-RA-018.

Q: Are there any compliance differences between these substitutes?

A: All four parts meet UL94 V-0 flammability requirements and carry RoHS compliance. The 68405-134HLF is RoHS Compliant; the three substitutes are ROHS3 Compliant, which represents a more recent revision of the RoHS standard. All parts are suitable for applications requiring these certifications.

Q: What should I consider regarding contact finish when selecting a substitute?

A: The 68405-134HLF uses gold or gold GXT™ finish on mating contacts. The 1-826634-7 and TSW-117-08-G-D-RA-018 use gold finish. The PEC17DGAN uses tin finish on mating contacts. Gold-finished contacts generally provide superior corrosion resistance and contact reliability. If the application environment is corrosive or requires extended shelf life, gold-finished substitutes are preferred.

Q: Can I use the TSW-117-08-G-D-RA-018 if only 33 of 34 positions are loaded?

A: The TSW-117-08-G-D-RA-018 specification indicates 33 positions loaded out of 34 total positions. Verify that your application design accommodates this configuration. If all 34 positions must be populated, select the 68405-134HLF, 1-826634-7, or PEC17DGAN, which specify all positions loaded.

Q: What is the significance of the operating temperature range differences?

A: The 68405-134HLF does not specify an operating temperature range. The 1-826634-7 operates from -65°C to 105°C, while the PEC17DGAN and TSW-117-08-G-D-RA-018 extend to 125°C. For applications requiring operation above 105°C, the PEC17DGAN or TSW-117-08-G-D-RA-018 are appropriate selections.

Q: Is the PEC17DGAN still available despite being discontinued at DiGi Electronics?

A: The PEC17DGAN is listed as discontinued at DiGi Electronics but may remain available through alternative distributors. Verify current inventory and lead times before committing to this substitute. The 1-826634-7 and TSW-117-08-G-D-RA-018 are active products with confirmed stock availability.
