ICA-322-SGT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-322-SGT is a 22-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated mating contacts. This socket accommodates dual inline packages with 0.3" row spacing and 0.100" pitch, operating across the industrial temperature range of -55°C to 125°C. The part maintains active product status with 861 units in current inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in circuit board designs without redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for DIP sockets is determined by strict alignment of critical electrical and mechanical parameters. The following parameters must match or be compatible:

Critical Matching Parameters:

• Number of positions: 22 (2 x 11)
• Row spacing: 0.3" (7.62mm)
• Pitch - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Contact finish - mating: Gold
• Operating temperature range: -55°C to 125°C minimum
• Termination: Solder

Allowable Variations:

• Contact finish thickness on mating contacts (within gold plating specifications)
• Post contact finish material and thickness (tin vs. tin-lead)
• Housing material composition (polyester variants)
• Current rating (substitute may exceed main part rating)
• Contact resistance (when not specified in main part)

The substitute part 110-93-322-41-001000 meets all critical matching parameters and qualifies as a functional equivalent.

Engineering Selection Recommendations

ICA-322-SGT Selection Criteria:

• Applications requiring ROHS3 compliance certification
• Designs specifying UL94 V-0 flammability rating
• Systems with strict RoHS material restrictions
• Tin post finish requirement for specific soldering processes

110-93-322-41-001000 Selection Criteria:

• Applications where RoHS compliance is not mandated
• Designs tolerating tin-lead post finish
• Systems benefiting from higher current rating (3 A vs. 1 A)
• Increased post contact finish thickness for enhanced durability
• Higher inventory availability (1220 units vs. 861 units)

Both parts maintain identical electrical and mechanical compatibility for DIP socket applications. Selection between these substitutes depends on regulatory compliance requirements and post finish specifications rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can 110-93-322-41-001000 directly replace ICA-322-SGT in existing PCB designs?

A: Yes, for applications not requiring ROHS3 compliance or UL94 V-0 certification. Both sockets share identical pin counts (22 positions), row spacing (0.3"), mating pitch (0.100"), and operating temperature range (-55°C to 125°C). PCB footprints and component placement remain unchanged.

Q: What is the significance of the post contact finish difference (Tin vs. Tin-Lead)?

A: Post finish affects solder joint formation during PCB assembly. Tin-lead finish (110-93-322-41-001000) provides enhanced wetting characteristics in traditional lead-containing solder processes. Tin finish (ICA-322-SGT) is compatible with lead-free solder systems. Selection depends on manufacturing process specifications.

Q: Why does 110-93-322-41-001000 have a higher current rating (3 A vs. 1 A)?

A: Current rating reflects the maximum continuous current the socket contacts can safely conduct. The Mill-Max part's higher rating indicates superior contact design or material properties. For applications requiring only 1 A, both parts perform identically. The higher rating provides additional design margin in the substitute part.

Q: Are there packaging differences between these two sockets?

A: Both parts are supplied in tube packaging. Tube packaging is standard for DIP sockets and ensures component protection during storage and handling. No functional or assembly differences result from this packaging method.

Q: What does the housing material difference (Polyester vs. PCT) mean for application performance?

A: Polycyclohexylenedimethylene Terephthalate (PCT) is a polyester variant offering enhanced thermal and chemical resistance compared to standard polyester. Both materials maintain the required operating temperature range (-55°C to 125°C) and provide adequate mechanical support for DIP socket applications. The difference is negligible for standard industrial applications.

Q: How does RoHS compliance affect part selection?

A: ROHS3 compliance (ICA-322-SGT) restricts hazardous substances in electrical equipment sold in the European Union and other regulated markets. RoHS non-compliance (110-93-322-41-001000) limits use in regulated applications but poses no technical performance difference. Selection depends on end-product regulatory requirements.
