Amphenol ICC 68705-104HLF Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68705-104HLF is a through-hole rectangular connector header from the BERGSTIK® II series, designed for board-to-board applications with 4 positions at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts, phosphor bronze contact material, and solder termination. The part is currently active in production with 797 units in stock.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative compliance certifications are required, or when design flexibility permits selection from equivalent connector families that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 68705-104HLF is determined by strict alignment with the following core parameters: connector type (header), contact type (male pin), mating pitch (0.100" / 2.54mm), number of positions (4), number of rows (1), mounting type (through hole), termination method (solder), fastening type (push-pull), and material flammability rating (UL94 V-0).

The substitute parts listed below maintain these critical parameters. Variations in contact finish (gold versus tin), contact material (phosphor bronze versus brass alloy versus copper alloy), insulation material, contact length dimensions, and compliance certifications (RoHS status, REACH status) are permitted within the substitute group, as these do not affect the fundamental mechanical and electrical compatibility of the connector header in standard board-to-board applications.

Engineering Selection Recommendations

For applications requiring active product status with current manufacturing support, the following parts are recommended: Molex 0423751246, TE Connectivity 5-146278-4, 5-146280-4, 5-146281-4, and 5-146282-4. These parts maintain UL94 V-0 flammability compliance and are currently in production.

For RoHS compliance requirements, select from: Amphenol ICC 68705-104HLF (original), Molex 0423751246, Mill-Max 350-10-104-00-006000, TE Connectivity 5-146278-4, 5-146280-4, 5-146281-4, 5-146282-4. Parts marked as RoHS non-compliant (TE Connectivity 4-103185-0-04, 4-103239-0-04, 4-103327-0-04) are obsolete and should not be selected for new designs.

The TE Connectivity AMPMODU Mod II series (5-146278-4, 5-146280-4, 5-146281-4, 5-146282-4) offers the highest inventory availability among active substitutes, with 4,766 to 24,407 units in stock. The Molex KK254 series (0423751246) provides an alternative from a different manufacturer with 23,912 units available.

Frequently Asked Questions (FAQ)

Q: Can the 68705-104HLF be directly replaced with any of the listed substitute parts?

A: Yes, all listed substitute parts maintain the critical mechanical and electrical parameters: 0.100" (2.54mm) pitch, 4-position single-row configuration, through-hole mounting, solder termination, and push-pull fastening. Physical board layout compatibility is ensured by these matching specifications.

Q: What is the difference between gold and tin contact finishes?

A: Contact finish is a surface treatment applied to the mating contact surfaces. Gold provides superior corrosion resistance and lower contact resistance over extended storage periods. Tin offers adequate performance for standard applications and is more cost-effective. Both finishes are electrically compatible in the same connector family.

Q: Are the obsolete TE Connectivity parts (4-103185-0-04, 4-103239-0-04, 4-103327-0-04, 5-146293-4) suitable for new designs?

A: Obsolete parts should not be selected for new designs. These parts are no longer manufactured and inventory is limited. For new applications, select from active product status parts: Molex 0423751246, Mill-Max 350-10-104-00-006000, or TE Connectivity 5-146278-4, 5-146280-4, 5-146281-4, 5-146282-4.

Q: What is the significance of RoHS compliance status?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the part does not contain restricted materials such as lead, cadmium, or hexavalent chromium. RoHS Compliant and ROHS3 Compliant parts meet current regulatory requirements. RoHS non-compliant parts may be restricted in certain markets and applications.

Q: Does the breakaway feature on some substitute parts affect compatibility?

A: The breakaway feature is a design characteristic that allows individual positions to be separated from the connector body. This feature does not affect electrical or mechanical compatibility with the original 68705-104HLF. Breakaway capability is an additional design option available on certain substitute models.

Q: What is the difference between contact materials (phosphor bronze, brass alloy, copper alloy)?

A: Contact material affects mechanical durability and electrical conductivity. Phosphor bronze (original part) provides excellent spring properties and corrosion resistance. Brass alloy and copper alloy alternatives offer similar electrical performance with variations in mechanical characteristics. All materials listed are suitable for the specified 5A current rating and 110V voltage rating.

Q: Can I use parts with different insulation materials?

A: Yes. The substitute parts use polyamide (PA), polycyclohexylenedimethylene terephthalate (PCT), or liquid crystal polymer (LCP) insulation materials. All materials meet UL94 V-0 flammability requirements and are compatible with the connector's electrical and thermal specifications.
