ICO-308-SST Equivalent & Substitute Parts

Part Overview

The ICO-308-SST is an 8-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring low-profile screw machine construction. This socket accommodates 8-pin (2 x 4) DIP packages with 0.3" row spacing and 0.100" pitch. The part is currently active in production with 949 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across critical specifications including pin count, pitch, row spacing, contact materials, mounting type, and operating temperature range. Alternative sources become necessary for supply chain continuity, inventory management, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-308-SST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 8 (2 x 4)
• Type: DIP with 0.3" (7.62mm) Row Spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 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
• Features: Open Frame

The substitute part 110-91-308-41-001000 (Mill-Max Manufacturing Corp.) meets all mandatory matching parameters and is classified as a direct electrical and mechanical equivalent for the ICO-308-SST.

Parameter Comparison

Engineering Selection Recommendations

ICO-308-SST (Samtec Inc.):

• Active product status with established supply chain
• ROHS3 compliant for regulated applications
• 1 A current rating with 10mOhm contact resistance specification
• Suitable for applications requiring RoHS compliance and documented contact resistance

110-91-308-41-001000 (Mill-Max Manufacturing Corp.):

• Active product status with 910 units in stock
• RoHS non-compliant; not suitable for applications with RoHS requirements
• 3 A current rating provides higher current capacity
• Tin-Lead post finish (200.0µin) versus tin post finish on main part
• Termination post length: 0.125" (3.18mm)
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Selection between these parts depends on regulatory compliance requirements and current rating specifications. The ICO-308-SST is required for RoHS-compliant applications. The 110-91-308-41-001000 is suitable for non-regulated applications where higher current capacity is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 110-91-308-41-001000 be used as a direct replacement for the ICO-308-SST in all applications?

A: The 110-91-308-41-001000 is electrically and mechanically equivalent for socket functionality. However, the ICO-308-SST is ROHS3 compliant while the 110-91-308-41-001000 is RoHS non-compliant. Applications subject to RoHS regulations must use the ICO-308-SST.

Q: What are the key electrical differences between these two parts?

A: The ICO-308-SST has a 1 A current rating with 10mOhm contact resistance. The 110-91-308-41-001000 has a 3 A current rating. Contact resistance for the Mill-Max part is not specified. Both parts maintain identical mating contact finish (gold, 10.0µin thickness) and beryllium copper contact material.

Q: Are the physical dimensions identical?

A: Both parts share identical pitch specifications (0.100" mating and post), 0.3" row spacing, and 8-position (2 x 4) DIP configuration. The Mill-Max part specifies a termination post length of 0.125" (3.18mm), which should be verified against PCB design requirements.

Q: What is the significance of the post finish difference?

A: The ICO-308-SST uses tin post finish, while the 110-91-308-41-001000 uses tin-lead post finish with 200.0µin thickness. This difference affects soldering characteristics and may impact lead-free assembly processes.

Q: Are there any moisture sensitivity considerations?

A: The 110-91-308-41-001000 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The ICO-308-SST does not specify an MSL rating.
