Amphenol ICC 68423-403 Rectangular Connector Header — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68423-403 is a through-hole, right-angle rectangular connector header with 3 positions at 0.100" (2.54mm) pitch, designed for board-to-board applications. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part features a male pin contact configuration with solder termination and push-pull fastening, suitable for applications requiring reliable low-voltage interconnection.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the 68423-403 is determined by strict alignment of the following core parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.100" / 2.54mm)
• Number of positions (3)
• Number of rows (1)
• Mounting type (Through Hole, Right Angle)
• Termination (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Material flammability rating (UL94 V-0)
• Insulation color (Black)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in contact length, contact finish, insulation height, and compliance status are secondary parameters that do not prevent functional substitution but may affect application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

68016-403HLF (Amphenol ICC) — Recommended primary substitute. Maintains the same manufacturer series (BERGSTIK® II) and operating temperature range (-65°C ~ 130°C). Active product status ensures long-term availability. RoHS compliant. Contact length variation (0.230" vs. 0.318") is the primary design consideration; verify PCB pad depth compatibility before implementation.

0022288031, 0022288033, 0022288035 (Molex KK254 Series) — Active alternatives from a different manufacturer. All three parts are ROHS3 compliant and feature breakaway connector capability. Contact length (0.324") is slightly longer than the original part. Molex parts feature polyamide insulation material versus unspecified material in the original. Operating temperature and current rating are not specified in the data; confirm application requirements before selection. Contact finish varies: 0022288031 uses tin finish; 0022288033 and 0022288035 use gold finish at different thicknesses (15.0µin and 30.0µin respectively).

87232-3 (TE Connectivity AMPMODU Mod II) — Active alternative with gold-plated contacts. Operating temperature range is reduced to -65°C ~ 105°C, which is lower than the original specification. Insulation height (0.138") is significantly larger than the original (0.095"), which may affect PCB layout compatibility. RoHS status is not applicable. Contact post length is slightly shorter (0.110" vs. 0.120").

Frequently Asked Questions (FAQ)

Q: Can I use 68016-403HLF as a direct replacement for 68423-403?

A: Yes, 68016-403HLF is the recommended substitute. Both are Amphenol ICC BERGSTIK® II series headers with identical pitch, position count, and operating temperature range. The primary difference is contact length (0.230" vs. 0.318"). Verify that your PCB pad depth accommodates the shorter contact length of the 68016-403HLF before implementation.

Q: What is the difference between the Molex parts (0022288031, 0022288033, 0022288035)?

A: All three Molex parts are functionally equivalent with identical core specifications. The differences are in contact finish: 0022288031 has tin finish (100.0µin), while 0022288033 and 0022288035 have gold finish at 15.0µin and 30.0µin thickness respectively. Gold finish provides enhanced corrosion resistance and is suitable for applications requiring higher reliability or extended shelf life.

Q: Why is the 87232-3 operating temperature range lower than the original part?

A: The 87232-3 (TE Connectivity AMPMODU Mod II) is rated for -65°C ~ 105°C, compared to the original -65°C ~ 130°C. If your application requires operation above 105°C, the 87232-3 is not suitable. Select 68016-403HLF or the Molex alternatives instead.

Q: Are all substitute parts RoHS compliant?

A: The original 68423-403 is RoHS non-compliant. The 68016-403HLF is RoHS compliant. The Molex parts (0022288031, 0022288033, 0022288035) are ROHS3 compliant. The 87232-3 has not applicable RoHS status. Confirm your application's RoHS requirements before final part selection.

Q: What is the significance of insulation height variation?

A: Insulation height affects the vertical profile of the connector on the PCB. The original part has 0.095" insulation height. The Molex parts have 0.098" (minimal difference), while the 87232-3 has 0.138" (significantly larger). If your PCB layout has height constraints or clearance requirements, verify that the substitute part's insulation height is compatible with your design.

Q: Can I mix and match these parts in the same assembly?

A: All substitute parts are functionally compatible with the same mating connector type (0.100" pitch, 3-position female receptacle). However, for consistency and to avoid potential contact resistance variations, use the same part number throughout an assembly or production run.

Q: What packaging options are available?

A: The 68016-403HLF is supplied in bag packaging. The Molex parts (0022288031, 0022288033, 0022288035) and 87232-3 are supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.
