Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The following parts are recommended as direct functional equivalents to the TE Connectivity 1-104427-2:

77311-822-14LF and 77311-846-14LF (Amphenol ICC BERGSTIK®) These parts provide the closest electrical and mechanical compatibility. Both maintain the 14-position, 2.54mm pitch configuration with identical contact mating length (0.318" for 77311-846-14LF) and post length specifications. Both are RoHS Compliant and rated for -65°C to 125°C operating temperature, exceeding the original part's temperature range. Current rating of 3A per contact matches the original specification. These parts are available in bulk packaging with high inventory levels (785 and 1050 units respectively).

77311-122-14LF (Amphenol ICC BERGSTIK®) This variant offers equivalent performance with slightly reduced contact mating length (0.305" versus 0.318"). It maintains 3A per contact current rating and -65°C to 125°C operating temperature. RoHS Compliant status and bulk packaging availability (1066 units in stock) make this a viable alternative.

54101-G3014LF (Amphenol ICC BERGSTIK®) This part meets all primary matching criteria with identical contact mating length (0.318") and post length (0.120"). It provides 3A per contact current rating and -65°C to 125°C operating temperature range. RoHS Compliant with 769 units in stock. Insulation height is increased to 0.100" (2.54mm) compared to the original 0.090" (2.29mm), which is acceptable for board-level applications.

Secondary Alternative:

68004-114HLF (Amphenol ICC BERGSTIK® II) This part offers enhanced current rating of 5A and maintains the 14-position, 2.54mm pitch configuration. It is RoHS Compliant with 883 units in stock. The reduced contact post length (0.107" versus 0.120") and increased insulation height (0.100") represent minor dimensional variations suitable for applications where additional current capacity is beneficial.

Compliance Considerations:

All substitute parts are RoHS Compliant, addressing regulatory requirements that the original obsolete part does not meet. The original TE Connectivity 1-104427-2 uses Tin-Lead contact finish on posts, whereas all substitutes employ Tin finish, aligning with modern manufacturing standards. All substitute parts maintain UL94 V-0 flammability rating and REACH Affected status consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC BERGSTIK® parts directly replace the TE Connectivity 1-104427-2 in existing designs?

A: Yes. All identified substitute parts maintain the critical functional parameters: 14 positions, 0.100" (2.54mm) pitch, male pin contacts, through-hole mounting, and unshrouded configuration. The dimensional variations in contact length and insulation height are within acceptable tolerances for board-level interconnect applications. Solder termination compatibility is maintained across all substitutes.

Q: What is the significance of the RoHS Compliant status of the substitute parts?

A: The original TE Connectivity 1-104427-2 is RoHS non-compliant due to its Tin-Lead contact finish. All substitute parts are RoHS Compliant, meeting current regulatory requirements for electronic components in many jurisdictions. This compliance status is essential for new production and applications subject to RoHS directives.

Q: Are there differences in contact material between the original and substitute parts?

A: Yes. The original part uses Copper Alloy contacts, while all Amphenol ICC substitutes employ Phosphor Bronze contacts. Phosphor Bronze provides superior spring characteristics and contact reliability, making it a preferred material for modern connector designs. This material change does not affect electrical compatibility.

Q: How do the operating temperature ranges compare?

A: The original TE Connectivity 1-104427-2 operates from -65°C to 105°C. All Amphenol ICC substitutes extend this range to -65°C to 125°C, providing enhanced thermal performance. This extended range is beneficial for applications subject to elevated ambient temperatures or thermal cycling.

Q: What is the difference between the BERGSTIK® and BERGSTIK® II series?

A: The BERGSTIK® II series (68004-114HLF) offers enhanced current rating of 5A compared to the standard BERGSTIK® series 3A rating. The BERGSTIK® II also features slightly reduced contact post length (0.107" versus 0.120"). Both series maintain the same pitch, position count, and mounting characteristics. Selection between series depends on application current requirements.

Q: Are there packaging differences among the substitute parts?

A: Yes. The 54101-G3014LF is supplied in Bag packaging, while 77311-822-14LF, 77311-122-14LF, and 77311-846-14LF are supplied in Bulk packaging. Packaging selection may affect handling, storage, and inventory management but does not impact electrical or mechanical performance.

Q: What is the significance of the contact finish thickness variations?

A: The original part specifies 15.0µin (0.38µm) gold finish thickness on mating contacts. Substitute parts 77311-822-14LF and 77311-846-14LF maintain this thickness, while 54101-G3014LF and 68004-114HLF provide 30.0µin (0.76µm) thickness. The increased thickness in some substitutes provides enhanced wear resistance and contact durability without affecting electrical compatibility.

Q: Can the 68004-114HLF be used in applications designed for 3A current rating?

A: Yes. The 68004-114HLF is rated for 5A per contact, which exceeds the 3A requirement of the original part. Using a higher-rated component in a lower-current application presents no compatibility issues and provides design margin for future current increases.

Q: What inventory availability should be considered for production planning?

A: Current inventory levels are: 77311-822-14LF (1050 units), 77311-122-14LF (1066 units), 68004-114HLF (883 units), 77311-846-14LF (785 units), and 54101-G3014LF (769 units). All parts are listed as New Original In Stock with active product status, ensuring reliable supply for ongoing production requirements.
