Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following core parameters:

• Number of Positions: 24 (2 x 12)
• DIP Type and Row Spacing: 0.3" (7.62mm)
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Through Hole
• Termination: Solder
• Pitch - Post: 0.100" (2.54mm)
• Termination Post Length: 0.125" (3.18mm)

Substitutes are classified into two categories:

Direct Substitutes: Parts meeting all core parameters with variations only in housing material, contact finish thickness on posts, or current rating specifications. These parts are suitable for direct replacement without design modification.

• 110-41-324-41-001000 (Mill-Max Manufacturing Corp.)
• 110-43-324-41-001000 (Mill-Max Manufacturing Corp.)
• 111-43-324-41-001000 (Mill-Max Manufacturing Corp.)
• 24-3518-10 (Aries Electronics)

Similar Parts: Parts meeting all core parameters but with compliance or material composition differences that may require design review.

• 110-93-324-41-001000 (Mill-Max Manufacturing Corp., RoHS non-compliant)

Engineering Selection Recommendations

For RoHS3 Compliant Applications:

110-43-324-41-001000, 111-43-324-41-001000, and 24-3518-10 are suitable direct substitutes. All three maintain ROHS3 compliance and match the operating temperature range of -55°C to 125°C. The primary differences are housing material composition and post contact finish thickness. 110-43-324-41-001000 and 111-43-324-41-001000 are functionally equivalent, with 111-43-324-41-001000 using a different housing material formulation (PCT/Polyester versus Thermoplastic). 24-3518-10 uses polyamide housing with glass fill and is supplied in bulk packaging rather than tube.

For Applications with Specified Current Rating:

110-43-324-41-001000, 111-43-324-41-001000, and 24-3518-10 are rated for 3 A, exceeding the 1 A specification of the ICA-324-SGT. 110-41-324-41-001000 does not specify a current rating and should be evaluated against application requirements.

For Flammability-Rated Applications:

ICA-324-SGT and 24-3518-10 both carry UL94 V-0 flammability ratings. Substitute parts 110-41-324-41-001000, 110-43-324-41-001000, and 111-43-324-41-001000 do not specify flammability ratings.

For Non-RoHS Applications:

110-93-324-41-001000 is available as a substitute for applications not requiring RoHS compliance. This part uses Tin-Lead post finish and is otherwise equivalent to the RoHS-compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can 110-43-324-41-001000 be used as a direct replacement for ICA-324-SGT?

A: Yes. Both parts share identical pin count (24), DIP type, row spacing (0.3"), mating pitch (0.100"), gold mating contact finish, beryllium copper mating contact material, through-hole mounting, solder termination, post pitch (0.100"), and termination post length (0.125"). Both are ROHS3 compliant and operate across -55°C to 125°C. The housing material differs (PCT/Polyester versus Polyester/Glass Filled), and the post contact finish thickness is thicker on the substitute (200.0µin versus 10.0µin), which does not affect compatibility.

Q: What is the difference between 110-43-324-41-001000 and 111-43-324-41-001000?

A: Both parts are functionally equivalent for socket applications. The primary difference is the housing material: 110-43-324-41-001000 uses PCT/Polyester, while 111-43-324-41-001000 uses PCT/Polyester as well. Both maintain identical electrical and mechanical specifications, ROHS3 compliance, and operating temperature range. Selection between these parts may be based on inventory availability or supplier preference.

Q: Why does 24-3518-10 come in bulk packaging instead of tube?

A: 24-3518-10 is supplied by Aries Electronics in bulk packaging, whereas Samtec and Mill-Max parts are supplied in tube packaging. This is a packaging format difference only and does not affect the socket's electrical or mechanical performance. Bulk packaging may require additional handling or reel management during assembly.

Q: Can I use 110-93-324-41-001000 if my application requires RoHS compliance?

A: No. 110-93-324-41-001000 is RoHS non-compliant due to its Tin-Lead post finish. For RoHS3 compliant applications, use 110-43-324-41-001000, 111-43-324-41-001000, or 24-3518-10.

Q: What is the significance of the contact finish thickness difference on the mating contacts?

A: ICA-324-SGT specifies 30.0µin (0.76µm) gold mating contact finish, while 110-41-324-41-001000 and 24-3518-10 specify 10.0µin (0.25µm). Both thicknesses provide adequate gold plating for electrical contact and corrosion resistance in standard applications. The thicker finish on ICA-324-SGT may provide extended contact life in high-cycle insertion applications.

Q: Are there operating temperature differences between the substitutes?

A: ICA-324-SGT, 110-43-324-41-001000, 111-43-324-41-001000, and 110-93-324-41-001000 all specify -55°C to 125°C operating temperature. 110-41-324-41-001000 and 24-3518-10 do not specify operating temperature ranges and should be evaluated against application thermal requirements.

Q: What is the current rating difference, and does it matter?

A: ICA-324-SGT is rated for 1 A, while 110-43-324-41-001000, 111-43-324-41-001000, and 24-3518-10 are rated for 3 A. Higher current rating indicates greater current-carrying capacity. For applications requiring only 1 A or less, all parts are suitable. For applications exceeding 1 A, the 3 A rated substitutes are required.
