Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-320-LGT 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
• Contact Material - Mating: Beryllium Copper
• Mounting Type: Through Hole
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C

The substitute part 115-93-320-41-001000 (Mill-Max Manufacturing Corp.) satisfies all mandatory matching parameters, establishing functional equivalence for direct component replacement in DIP socket applications.

Parameter Comparison

Engineering Selection Recommendations

ICO-320-LGT (Samtec Inc.) is the primary component selection for applications requiring RoHS3 compliance. This part maintains active product status and meets all regulatory requirements for restricted substance compliance.

115-93-320-41-001000 (Mill-Max Manufacturing Corp.) provides functional equivalence for DIP socket applications where RoHS compliance is not a design requirement. This substitute offers higher current rating (3 A versus 1 A) and increased inventory availability. However, this part is RoHS non-compliant and contains tin-lead solder finish on posts, which may restrict use in regulated industries or applications with lead-free soldering requirements.

Selection between these parts depends on regulatory compliance mandates and current rating requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can 115-93-320-41-001000 replace ICO-320-LGT in all applications?

A: Functional replacement is possible for applications where RoHS compliance is not mandated. Both parts share identical mating contact specifications, row spacing, pitch, and operating temperature range. However, the substitute part is RoHS non-compliant and contains tin-lead post finish, which may violate design requirements in regulated markets.

Q: What are the key differences between these two DIP sockets?

A: The primary differences are RoHS compliance status (ICO-320-LGT is compliant; 115-93-320-41-001000 is non-compliant), current rating (1 A versus 3 A), and post contact finish (tin versus tin-lead). Mating contact specifications, position count, row spacing, and operating temperature range are identical.

Q: Are the housing materials interchangeable?

A: Both parts use polyester-based housing materials with glass or PCT reinforcement. The housing materials differ in composition but serve equivalent mechanical and thermal functions for DIP socket applications. No functional impact on socket performance is introduced by this material variation.

Q: Does the higher current rating of 115-93-320-41-001000 affect compatibility?

A: The higher current rating (3 A) of the Mill-Max part does not create incompatibility. Current rating represents maximum allowable current; a part rated for higher current can be used in applications requiring lower current without performance degradation.

Q: What is the significance of tin-lead versus tin post finish?

A: Tin-lead finish (115-93-320-41-001000) contains lead and is restricted in RoHS-regulated applications. Tin finish (ICO-320-LGT) is lead-free and compliant with RoHS3 requirements. This distinction is critical for applications subject to environmental or regulatory restrictions on hazardous substances.
