ICO-316-LGT Equivalent & Substitute Parts

Part Overview

The ICO-316-LGT is a 16-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated mating contacts and tin-plated brass posts. This component is classified as an active product with full inventory availability. Equivalent and substitute parts are identified to support procurement flexibility, design redundancy, and supply chain continuity when the primary part becomes unavailable or when alternative specifications better suit specific application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for DIP sockets is determined by strict alignment of mechanical and electrical parameters. The following criteria establish functional equivalence:

Critical Parameters for Substitution:

Number of positions and grid configuration (16 positions, 2 x 8 arrangement)
Row spacing (0.3" / 7.62mm)
Mating pitch (0.100" / 2.54mm)
Post pitch (0.100" / 2.54mm)
Contact finish on mating surface (Gold)
Mounting type (Through Hole)
Operating temperature range (-55°C ~ 125°C)

The substitute part 115-93-316-41-001000 (Mill-Max Manufacturing Corp.) satisfies all critical mechanical parameters and maintains functional compatibility with the ICO-316-LGT within the specified operating envelope.

Engineering Selection Recommendations

ICO-316-LGT Selection Criteria:

Applications requiring ROHS3 compliance
Designs with strict regulatory requirements for hazardous substance restrictions
Systems where compliance documentation is mandatory

115-93-316-41-001000 Selection Criteria:

Applications where RoHS compliance is not a requirement
Designs requiring higher current capacity (3 A vs. 1 A rating)
Legacy systems or non-regulated applications
Supply chain scenarios where Samtec inventory is unavailable

Both parts maintain identical mechanical compatibility and operate within the same temperature envelope. Selection between these parts should be based on regulatory compliance requirements and current rating specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 115-93-316-41-001000 be used as a direct replacement for the ICO-316-LGT?

A: Yes, from a mechanical and thermal standpoint. Both sockets accommodate 16-position DIP packages with 0.3" row spacing and 0.100" pitch. However, the RoHS compliance status differs. The ICO-316-LGT is ROHS3 compliant, while the 115-93-316-41-001000 is RoHS non-compliant. Selection depends on regulatory requirements for your application.

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

A: The current rating indicates the maximum continuous current the socket contacts can safely carry. The 115-93-316-41-001000 has a higher rating (3 A), which provides greater margin for high-current applications. The ICO-316-LGT is rated at 1 A. Both are suitable for standard DIP package applications; selection should reflect actual circuit current requirements.

Q: Are the contact finishes identical?

A: Both parts feature gold-plated mating contacts (30.0µin thickness). The post finishes differ: ICO-316-LGT uses tin plating (10.0µin), while 115-93-316-41-001000 uses tin-lead plating (200.0µin). This difference does not affect functional compatibility for standard through-hole soldering applications.

Q: What does "Open Frame" mean in the Features field?

A: Open Frame indicates the socket lacks a full plastic housing around the contact array. Both the ICO-316-LGT and 115-93-316-41-001000 use this design, which reduces material cost and allows direct access to contacts for inspection and cleaning.

Q: Can these sockets be used in high-temperature applications?

A: Both sockets operate across the -55°C to 125°C temperature range. This specification covers standard industrial and commercial applications. Verify that your specific application does not exceed these limits.
