ICO-316-STT Equivalent & Substitute Parts

Part Overview

The ICO-316-STT is a 16-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring low-profile screw machine construction. This socket accommodates 0.3" (7.62mm) row spacing with 0.100" (2.54mm) pitch mating contacts. The part is currently in active production status with 703 units available in inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design revisions require alternative sourcing options that maintain electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 110-99-316-41-001000 qualifies as a substitute for the ICO-316-STT based on the following matched parameters:

Matched Electrical and Mechanical Parameters:

• 16-position DIP socket configuration (2 x 8 arrangement)
• 0.3" (7.62mm) row spacing
• 0.100" (2.54mm) pitch for both mating and post contacts
• Through-hole solder termination
• Open frame design
• Beryllium copper mating contacts
• Brass alloy post contacts
• Polyester-based housing material

Substitution Validity: Both parts maintain identical mechanical footprints, contact pitch, and mounting interfaces. The substitute part accommodates the same DIP package family and printed circuit board hole patterns. Contact material composition and housing material families remain compatible within the DIP socket category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (ICO-316-STT): The ICO-316-STT is the preferred selection for applications requiring ROHS3 compliance. This part maintains active production status and meets regulatory requirements for restricted substance compliance. The specified contact resistance of 10 mOhm and 1 A current rating define the electrical performance envelope for this socket family.

Substitute Part Selection (110-99-316-41-001000): The Mill-Max 110-99-316-41-001000 serves as a functional substitute when ICO-316-STT availability is constrained. This part provides higher current capacity (3 A) and extended operating temperature range (-55°C to 125°C). However, this substitute is RoHS non-compliant and incorporates tin-lead contact finish rather than tin finish. Selection of this substitute requires confirmation that the application does not mandate RoHS compliance and that tin-lead contact finish is acceptable for the intended circuit environment.

Both parts share identical mechanical interfaces, pitch specifications, and DIP socket configuration, ensuring PCB compatibility and component interchangeability at the physical level.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 110-99-316-41-001000 be used as a direct replacement for the Samtec ICO-316-STT?

A: Yes, from a mechanical and electrical interface perspective. Both parts maintain 16-position DIP configuration with 0.100" (2.54mm) pitch and 0.3" (7.62mm) row spacing. However, regulatory compliance differs: the ICO-316-STT is ROHS3 compliant while the Mill-Max part is RoHS non-compliant. Contact finish differs (tin versus tin-lead). Substitution is valid only when RoHS compliance is not a design requirement.

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

A: The primary differences are: (1) Contact finish composition—ICO-316-STT uses tin finish; 110-99-316-41-001000 uses tin-lead finish; (2) RoHS compliance status—ICO-316-STT is ROHS3 compliant; 110-99-316-41-001000 is non-compliant; (3) Current rating—ICO-316-STT rated at 1 A; 110-99-316-41-001000 rated at 3 A; (4) Operating temperature—ICO-316-STT operates -55°C to 105°C; 110-99-316-41-001000 operates -55°C to 125°C.

Q: Are the PCB footprints identical between these parts?

A: Yes. Both parts maintain identical 16-position DIP configuration with 0.100" (2.54mm) pitch spacing and 0.3" (7.62mm) row spacing. PCB hole patterns and mounting interfaces are identical, ensuring direct physical interchangeability.

Q: Which part should be selected for new designs?

A: For new designs, the ICO-316-STT is the recommended selection due to active production status and ROHS3 compliance alignment with current regulatory standards. The Mill-Max substitute should be considered only when supply constraints on the primary part occur or when application requirements specifically permit RoHS non-compliant components.

Q: Does the higher current rating of the Mill-Max part affect compatibility?

A: No. The higher 3 A current rating of the 110-99-316-41-001000 does not create compatibility issues. Applications designed for the 1 A ICO-316-STT will operate within the electrical envelope of the 3 A substitute. The substitute provides additional current capacity margin without affecting circuit function.
