ICO-632-LGT Equivalent & Substitute Parts

Part Overview

The ICO-632-LGT is a 32-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated mating contacts. This component is classified as an active product with full inventory availability. The socket accommodates dual inline package (DIP) integrated circuits with 0.6" row spacing and 0.100" pitch contacts.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across critical specifications including pin count, pitch dimensions, contact materials, and operating temperature range. Identifying qualified substitutes ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-632-LGT is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pin count: 32 positions (2 x 16 configuration)
• Pitch spacing: 0.100" (2.54mm) mating pitch
• Row spacing: 0.6" (15.24mm)
• Contact finish material: Gold plating on mating contacts
• Mating contact material: Beryllium Copper
• Operating temperature range: -55°C ~ 125°C minimum

Mechanical Compatibility Parameters:

• Socket type: DIP configuration
• Mounting method: Through-hole solder termination
• Housing material: Polyester or equivalent thermoplastic
• Features: Open frame design

The substitute part 115-93-632-41-001000 (Mill-Max Manufacturing Corp.) maintains equivalence across all critical electrical and mechanical parameters, enabling direct functional substitution in applications where the ICO-632-LGT is specified.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ICO-632-LGT (Samtec Inc.)

The ICO-632-LGT is the specified component and maintains active product status with ROHS3 compliance certification. This part is recommended for new designs and applications where RoHS3 compliance is a contractual or regulatory requirement.

Substitute Selection: 115-93-632-41-001000 (Mill-Max Manufacturing Corp.)

The 115-93-632-41-001000 provides functional equivalence across all critical electrical and mechanical parameters. This substitute is suitable for applications where:

• Identical pin count, pitch, and row spacing are required
• Gold-plated mating contacts with beryllium copper material are specified
• Through-hole mounting with solder termination is required
• Operating temperature range of -55°C ~ 125°C is maintained

Compliance Considerations:

The ICO-632-LGT carries ROHS3 compliance certification. The 115-93-632-41-001000 is identified as RoHS non-compliant. Selection between these parts must account for end-product regulatory requirements and customer specifications regarding RoHS compliance status.

Current Rating Differential:

The Mill-Max substitute (115-93-632-41-001000) is rated for 3 A continuous current, compared to 1 A for the Samtec ICO-632-LGT. This higher current rating in the substitute does not create incompatibility and may provide additional design margin in applications requiring elevated current handling.

Frequently Asked Questions (FAQ)

Q: Can the 115-93-632-41-001000 be used as a direct replacement for the ICO-632-LGT?

A: Yes. Both parts maintain equivalent pin count (32 positions), pitch spacing (0.100"), row spacing (0.6"), contact materials (gold-plated beryllium copper mating contacts), and operating temperature range (-55°C ~ 125°C). Mechanical and electrical compatibility is established across all critical parameters.

Q: What is the primary difference between these two socket parts?

A: The primary differences are manufacturer identity and regulatory compliance status. The ICO-632-LGT is ROHS3 compliant, while the 115-93-632-41-001000 is RoHS non-compliant. The Mill-Max part also carries a higher current rating (3 A versus 1 A). Both parts are functionally equivalent for DIP socket applications.

Q: Are the contact materials identical between the two parts?

A: Mating contacts are identical: both use gold plating (30.0µin thickness) over beryllium copper. Post contacts differ slightly in material designation (Brass versus Brass Alloy) and finish thickness (10.0µin tin versus 200.0µin tin-lead), but both maintain equivalent electrical performance for through-hole solder termination.

Q: Which part should be selected for RoHS-compliant applications?

A: The ICO-632-LGT (Samtec) is ROHS3 compliant and is the appropriate selection for applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance.

Q: Are there any temperature or current limitations when using the substitute part?

A: Both parts operate across the identical temperature range (-55°C ~ 125°C). The 115-93-632-41-001000 is rated for higher continuous current (3 A versus 1 A), which does not create a limitation for substitution. Applications requiring the full 3 A rating would benefit from the Mill-Max part.

Q: What is the packaging format for both parts?

A: Both the ICO-632-LGT and 115-93-632-41-001000 are supplied in tube packaging, suitable for automated assembly and manual component handling.

Q: Can these sockets accommodate different DIP package sizes?

A: No. Both sockets are configured specifically for 32-position DIP packages with 0.6" row spacing and 0.100" pitch. They are not compatible with DIP packages of different pin counts or spacing configurations.
