Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-320-NGT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 20 (2 x 10)
• Row Spacing: 0.3" (7.62mm)
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C to 125°C

The substitute part 115-93-320-41-003000 (Mill-Max Manufacturing Corp.) satisfies all mandatory parameters. Both components feature identical DIP socket configurations with matching contact geometry, gold mating surfaces, and through-hole solder termination. Both operate across the full -55°C to 125°C temperature range, ensuring functional equivalence in standard IC socket applications.

Parameter Comparison

Engineering Selection Recommendations

ICO-320-NGT Selection Criteria:

• Applications requiring ROHS3 compliance
• Designs with RoHS-compliant supply chain requirements
• Specifications explicitly calling for Samtec manufacturing

115-93-320-41-003000 Selection Criteria:

• Applications where RoHS compliance is not mandated
• Designs tolerating higher current ratings (3 A vs. 1 A)
• Supply scenarios where Mill-Max inventory availability is advantageous
• Applications compatible with Tin-Lead post finishes

Both components are active products with confirmed inventory availability. The primary differentiation factor is regulatory compliance status: the ICO-320-NGT maintains ROHS3 certification, while the 115-93-320-41-003000 is RoHS non-compliant. Selection between these parts depends on whether the end application or customer requirements mandate RoHS compliance. All other electrical and mechanical parameters support direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the 115-93-320-41-003000 directly replace the ICO-320-NGT on a PCB?

A: Yes, from a mechanical and electrical standpoint. Both sockets feature identical 20-position DIP configurations with 0.3" row spacing, 0.100" pitch, gold mating contacts, and through-hole solder termination. PCB footprints are interchangeable. However, RoHS compliance status differs; verify regulatory requirements before substitution.

Q: What is the significance of the different post finishes (Tin vs. Tin-Lead)?

A: Post finish affects solder joint formation during PCB assembly. Tin finish (ICO-320-NGT) is RoHS-compliant and suitable for lead-free solder processes. Tin-Lead finish (115-93-320-41-003000) is compatible with traditional lead-containing solder. Both finishes support reliable solder connections; selection depends on assembly process specifications.

Q: Why does the Mill-Max part have a higher current rating (3 A vs. 1 A)?

A: Current rating reflects the maximum continuous current the socket contacts can safely carry. The Mill-Max 115-93-320-41-003000 demonstrates higher current capacity, making it suitable for applications requiring greater current handling. For standard IC socket applications operating within 1 A limits, both parts perform equivalently.

Q: Are the housing materials functionally equivalent?

A: Yes. The ICO-320-NGT uses polyester with glass filler; the 115-93-320-41-003000 uses polycyclohexylenedimethylene terephthalate (PCT) polyester. Both materials provide adequate mechanical support, thermal stability across the -55°C to 125°C operating range, and UL94 V-0 flammability ratings. Housing material differences do not affect socket functionality in standard applications.

Q: What does "Open Frame" feature mean?

A: Open Frame indicates the socket lacks a protective shroud or cover. Both the ICO-320-NGT and 115-93-320-41-003000 feature open frame construction, allowing direct access to contact positions. This design is standard for DIP sockets and does not affect substitution compatibility.

Q: Can I use the 115-93-320-41-003000 in a design requiring ROHS3 certification?

A: No. The 115-93-320-41-003000 is RoHS non-compliant. For applications or products requiring ROHS3 certification, the ICO-320-NGT must be specified. Substitution with a non-compliant part would violate regulatory requirements.

Q: Are both parts suitable for -55°C to 125°C operating environments?

A: Yes. Both the ICO-320-NGT and 115-93-320-41-003000 are rated for -55°C to 125°C operation. This identical temperature range ensures functional equivalence across standard industrial and commercial temperature environments.
