Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-422-SGT is determined by strict alignment of the following critical parameters:

Position Count and Pitch: The substitute part must have exactly 22 positions arranged in a 2 x 11 configuration with 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) post pitch. These parameters define mechanical compatibility with standard DIP packages.

Row Spacing: The 0.4" (10.16mm) row spacing is mandatory for physical fit and electrical performance in target applications.

Contact Finish - Mating: Gold plating on mating contacts is required to maintain signal integrity and corrosion resistance across the operating temperature range.

Mounting Configuration: Through-hole solder termination is the required mounting method for PCB integration.

Operating Temperature: The -55°C to 125°C range establishes the thermal envelope for industrial applications.

The identified substitute part, 110-93-422-41-001000 from Mill-Max Manufacturing Corp., meets all critical substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

ICO-422-SGT (Samtec Inc.): This part is RoHS3 compliant and carries a UL94 V-0 material flammability rating. It is the primary choice for applications requiring strict RoHS compliance and enhanced flammability performance. The part is active in production with established supply availability.

110-93-422-41-001000 (Mill-Max Manufacturing Corp.): This substitute part is RoHS non-compliant and does not specify a material flammability rating. However, it offers a higher current rating of 3 A compared to the 1 A rating of the primary part, and provides greater inventory availability (1373 units in stock versus 699 units). Selection of this substitute is appropriate only when RoHS compliance is not a design requirement and higher current capacity is beneficial.

Both parts share identical mechanical dimensions, pitch specifications, and operating temperature ranges, ensuring direct physical and electrical compatibility in DIP socket applications.

Frequently Asked Questions (FAQ)

Q: Can the 110-93-422-41-001000 be used as a direct replacement for the ICO-422-SGT?

A: Direct replacement is possible from a mechanical and electrical standpoint, as both parts share identical position counts, pitch specifications, row spacing, and operating temperature ranges. However, the substitute part is RoHS non-compliant, whereas the primary part is RoHS3 compliant. Design requirements and regulatory constraints must be evaluated before substitution.

Q: What are the differences in contact finish between these two parts?

A: Both parts feature gold-plated mating contacts with identical 30.0µin (0.76µm) thickness. The post contact finish differs: the ICO-422-SGT uses tin plating at 10.0µin (0.25µm), while the 110-93-422-41-001000 uses tin-lead plating at 200.0µin (5.08µm). The tin-lead finish on the substitute part provides thicker post plating.

Q: Why does the substitute part have a higher current rating?

A: The 110-93-422-41-001000 is rated for 3 A compared to the 1 A rating of the ICO-422-SGT. This difference reflects the design specifications of each manufacturer's socket construction. Applications requiring higher current capacity may benefit from the substitute part's increased rating.

Q: Are there any flammability or compliance differences?

A: The ICO-422-SGT carries a UL94 V-0 material flammability rating and is RoHS3 compliant. The 110-93-422-41-001000 does not specify a flammability rating and is RoHS non-compliant. Applications in regulated industries or those requiring flame-retardant materials should use the primary part.

Q: Do both parts use the same housing material?

A: Both parts use polyester-based housing materials. The ICO-422-SGT specifies polyester with glass filling, while the 110-93-422-41-001000 uses polycyclohexylenedimethylene terephthalate (PCT) combined with polyester. Both materials support the identical -55°C to 125°C operating temperature range.

Q: What is the termination post length difference?

A: The ICO-422-SGT does not specify a termination post length in the provided data. The 110-93-422-41-001000 specifies a post length of 0.125" (3.18mm). This parameter should be verified against PCB design requirements before substitution.
