ICO-320-SGG DIP Socket Equivalent & Substitute Parts

Part Overview

The ICO-320-SGG is a 20-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated beryllium copper contacts. This component is classified as an IC socket with 0.3" (7.62mm) row spacing and 0.100" (2.54mm) pitch mating contacts. The part maintains active product status with 899 units in current inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in circuit designs without functional degradation. Substitution becomes necessary when primary part availability is limited, supply chain constraints occur, or design flexibility is required across multiple qualified component sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for DIP socket components is determined by strict alignment of critical electrical and mechanical parameters. The following parameters establish substitution validity:

Primary Substitution Criteria:

• Number of positions and grid configuration (20 positions, 2 x 10 arrangement)
• Row spacing (0.3" / 7.62mm)
• Mating pitch (0.100" / 2.54mm)
• Contact finish material (Gold plating on mating contacts)
• Mounting type (Through Hole)
• Operating temperature range (-55°C ~ 125°C minimum)
• Contact material for mating surface (Beryllium Copper)

Compliance Requirements:

• RoHS3 compliance status
• ECCN classification (EAR99)
• HTSUS commodity code alignment

The substitute part 110-13-320-41-001000 (Mill-Max Manufacturing Corp.) satisfies all primary substitution criteria and maintains equivalent compliance certifications, establishing it as a direct functional equivalent for the ICO-320-SGG.

Parameter Comparison

Engineering Selection Recommendations

Both the ICO-320-SGG and 110-13-320-41-001000 maintain active product status with confirmed ROHS3 compliance and identical ECCN/HTSUS classifications, establishing them as qualified alternatives for procurement and design applications.

Selection Basis:

The ICO-320-SGG (Samtec) is the primary specified component with documented UL94 V-0 flammability certification and 1 A current rating. This part is suitable for applications requiring certified flammability performance and standard current loads.

The 110-13-320-41-001000 (Mill-Max) provides equivalent mechanical and electrical interface compatibility with identical mating contact specifications, operating temperature range, and compliance certifications. The Mill-Max part carries a 3 A current rating, providing additional margin for higher-current applications. The post contact finish thickness specification (10.0µin vs. 30.0µin) represents a variance in plating thickness that does not affect substitution validity for standard through-hole solder termination applications.

Selection between these parts is determined by availability, supply chain requirements, and application-specific current demands. Both parts are suitable for direct substitution in DIP socket applications requiring 20-position, 0.3" row spacing configurations with gold-plated beryllium copper mating contacts.

Frequently Asked Questions (FAQ)

Q: Can the 110-13-320-41-001000 directly replace the ICO-320-SGG in existing PCB designs?

A: Yes. Both parts share identical mechanical footprints (20 positions, 0.3" row spacing, 0.100" pitch), identical mating contact materials (beryllium copper with gold plating), and equivalent through-hole solder termination specifications. No PCB layout modifications are required.

Q: What is the significance of the different current ratings (1 A vs. 3 A)?

A: The current rating indicates the maximum continuous current each contact can safely carry. The ICO-320-SGG is rated for 1 A per contact, while the 110-13-320-41-001000 is rated for 3 A per contact. For applications requiring currents below 1 A, both parts are equivalent. For applications requiring 1-3 A per contact, the Mill-Max part provides additional capacity.

Q: Are there differences in contact plating thickness between these parts?

A: Yes. The ICO-320-SGG specifies 30.0µin (0.76µm) gold plating on both mating and post contacts. The 110-13-320-41-001000 specifies 30.0µin on mating contacts and 10.0µin (0.25µm) on post contacts. Both thicknesses meet industry standards for through-hole solder applications and do not affect substitution validity.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the ICO-320-SGG and 110-13-320-41-001000 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C, ensuring equivalent thermal performance in standard industrial and commercial applications.

Q: Is the UL94 V-0 flammability rating available for the Mill-Max part?

A: The UL94 V-0 flammability rating is specified for the ICO-320-SGG but is not documented in the provided specifications for the 110-13-320-41-001000. Applications requiring certified flammability performance should specify the ICO-320-SGG or confirm flammability certification with Mill-Max Manufacturing Corp. directly.
