Engineering Selection Recommendations

Primary Substitutes for Direct Replacement:

The Amphenol ICC (FCI) BERGSTIK® II series components 68691-126HLF and 78548-226HLF provide the closest functional equivalence to the TE Connectivity 1-104432-3. Both parts maintain identical pitch specifications, position counts, and contact mating lengths. These components are currently in active production status with RoHS compliance certification, addressing the obsolescence of the original part. The 78548-226HLF offers additional compliance advantage with ROHS3 certification and is available in higher inventory quantities.

Secondary Substitutes with Minor Parameter Variations:

The Amphenol ICC BERGSTIK® series parts 77313-422-26LF and 77313-822-26LF are functionally equivalent with active product status and RoHS compliance. These components feature slightly shorter contact mating lengths (0.305" versus 0.318") and increased insulation height (0.100" versus 0.090"), which remain within acceptable tolerances for standard board-to-board interconnection applications. The 77313-822-26LF provides gold-plated mating contacts with reduced finish thickness (15.0µin), suitable for applications requiring enhanced corrosion resistance.

Alternative Substitutes with Extended Temperature Range:

The Preci-Dip 892-18-026-10-002101 and Amphenol ICC BERGSTIK® II series components offer extended operating temperature ranges (-55°C to 125°C or higher) compared to the original part specification. These components maintain 3A current ratings and UL94 V-0 flammability compliance. The Preci-Dip component features ROHS3 compliance and is suitable for applications requiring broader thermal operating windows.

Compliance-Driven Selection:

For applications requiring RoHS compliance, all listed substitute parts except the original TE Connectivity 1-104432-3 meet current regulatory requirements. The 3M 929665-01-13-I and Hirose Electric A1-26PA-2.54DSA(71) components provide RoHS compliance with active product status, though the 3M component operates at a reduced current rating of 2.5A and the Hirose component has a narrower operating temperature range (-55°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 78548-226HLF directly replace the TE Connectivity 1-104432-3 in existing designs?

A: Yes. The 78548-226HLF maintains identical pitch (0.100"), position count (26 in 2 rows), contact mating length (0.318"), and fastening type (push-pull). Both components feature square male pin contacts with UL94 V-0 flammability rating and unshrouded design. The primary difference is the kinked pin termination option in the substitute, which is compatible with standard solder processes. The substitute is RoHS compliant and in active production.

Q: What are the key differences between the Amphenol ICC BERGSTIK® II and BERGSTIK® series substitutes?

A: The BERGSTIK® II series (68691-126HLF, 78548-226HLF, 78548-626) features kinked pin termination and phosphor bronze contact material. The BERGSTIK® series (77313-422-26LF, 77313-822-26LF) offers standard solder termination with the same contact material. Both series maintain identical pitch and position specifications. The BERGSTIK® II components provide slightly longer contact mating lengths (0.318" versus 0.305") and are available in both bag and bulk packaging options.

Q: Are there current rating differences between substitute options?

A: Most substitutes maintain the 3A current rating of the original part. The 3M 929665-01-13-I operates at 2.5A, which is suitable for applications not requiring the full 3A capacity. The Amphenol ICC 78548-226HLF and 78548-626 do not specify current ratings in available documentation but are mechanically and electrically compatible with 3A applications based on contact geometry and material specifications.

Q: Which substitute offers the best compliance profile for new designs?

A: The Amphenol ICC 78548-226HLF provides optimal compliance for new designs, combining RoHS compliance, ROHS3 certification, active product status, and high inventory availability (1039 pieces). The component features kinked pin solder termination, polycyclohexylenedimethylene terephthalate (PCT) insulation material, and gold-plated mating contacts with 15.0µin finish thickness. This part is suitable for both legacy replacement and new design implementation.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: bag packaging (68691-126HLF, 77313-422-26LF, 77313-822-26LF, 78548-226HLF), bulk packaging (78548-126, 78548-626, 892-18-026-10-001101, 892-18-026-10-002101, 929665-01-13-I), and tray packaging (A1-26PA-2.54DSA(71)). Selection depends on production volume requirements and inventory management protocols.

Q: Are there operating temperature considerations when selecting a substitute?

A: The original TE Connectivity 1-104432-3 operates from -65°C to 105°C. Most substitutes offer extended temperature ranges: Amphenol ICC BERGSTIK® series components operate to -65°C to 130°C, Preci-Dip 892 series to -55°C to 125°C, and 3M 929665-01-13-I to -40°C to 105°C. The Hirose A1-26PA-2.54DSA(71) operates to -55°C to 85°C, which is narrower than the original specification. For applications requiring the full -65°C lower temperature limit, Amphenol ICC BERGSTIK® series components are recommended.

Q: What is the significance of contact finish variations among substitutes?

A: Contact finish thickness affects corrosion resistance and contact reliability. The original part features 30.0µin (0.76µm) gold plating on mating contacts. Substitutes range from 8.00µin to 78.7µin thickness. Higher finish thickness (78.7µin) provides enhanced corrosion resistance for harsh environments. Lower thickness (8.00µin to 15.0µin) is suitable for standard indoor applications. Gold-plated contacts (all substitutes except 77313-422-26LF) provide superior performance compared to tin-plated alternatives.

Q: Can the Preci-Dip 892-18-026-10-002101 be used as a substitute despite different contact material?

A: Yes. The Preci-Dip component uses brass contact material instead of copper alloy or phosphor bronze. Brass provides equivalent electrical conductivity and mechanical properties for standard interconnection applications. The component maintains identical pitch, position count, and fastening specifications. The 3A current rating and 150VDC voltage rating exceed the original part's 30VAC specification, confirming electrical compatibility.

Q: What are the inventory implications when selecting a substitute?

A: Current inventory levels vary significantly among substitutes. The 3M 929665-01-13-I offers the highest availability (7386 pieces), followed by Amphenol ICC 78548-626 (1059 pieces) and 78548-226HLF (1039 pieces). The Hirose A1-26PA-2.54DSA(71) has the lowest availability (682 pieces). For high-volume production requirements, the 3M or Amphenol ICC BERGSTIK® II series components are recommended based on inventory levels and active production status.
