The substitute parts 115-43-316-41-001000 and 115-93-316-41-001000 (Mill-Max Manufacturing Corp.) satisfy all mechanical compatibility requirements and maintain equivalent electrical performance through identical position counts, row spacing, pitch specifications, and contact materials. Both substitute parts exceed the operating temperature range of the original component and provide enhanced current rating capacity.

Parameter Comparison

Engineering Selection Recommendations

115-43-316-41-001000 (Mill-Max Manufacturing Corp.): This substitute part maintains full ROHS3 compliance matching the original ICO-316-LTT specification. The gold contact finish on mating surfaces provides enhanced corrosion resistance compared to the tin finish of the original component. The extended operating temperature range (-55°C to 125°C) and increased current rating (3 A versus 1 A) represent performance enhancements suitable for applications requiring higher thermal or electrical margins. Product status is active with equivalent moisture sensitivity and REACH compliance.

115-93-316-41-001000 (Mill-Max Manufacturing Corp.): This substitute part provides identical mechanical and electrical compatibility with the original component. The tin-lead post finish and brass alloy post material maintain functional equivalence. However, this part carries RoHS non-compliant status, making it unsuitable for applications subject to RoHS3 regulatory requirements. The extended operating temperature range (-55°C to 125°C) and increased current rating (3 A) are equivalent to the 115-43 variant. Product status is active with equivalent moisture sensitivity and REACH compliance.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 115-43-316-41-001000 be used as a direct replacement for the Samtec ICO-316-LTT?

A: Yes. Both components share identical mechanical dimensions, position counts, row spacing, pitch specifications, and contact materials. The 115-43 variant maintains ROHS3 compliance and provides enhanced performance through gold mating contacts, extended temperature range, and higher current rating.

Q: What is the primary difference between the two Mill-Max substitute parts?

A: The 115-43-316-41-001000 maintains ROHS3 compliance with gold mating contacts, while the 115-93-316-41-001000 is RoHS non-compliant with tin-lead post finish. Both share identical mechanical compatibility and enhanced electrical performance specifications.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist for mechanical or electrical performance. All three parts maintain identical position counts, row spacing, pitch specifications, and contact materials. Selection should be based on regulatory compliance requirements and performance margin needs.

Q: How do the current ratings compare across these components?

A: The original ICO-316-LTT is rated for 1 A, while both Mill-Max substitutes are rated for 3 A. This represents a performance enhancement and does not create compatibility issues in applications designed for the original 1 A specification.

Q: What is the significance of the contact finish differences?

A: The original ICO-316-LTT uses tin mating contacts, while both Mill-Max substitutes use gold mating contacts. Gold provides superior corrosion resistance and lower contact resistance over extended service life, particularly in environments with moisture or thermal cycling.

Q: Are the operating temperature ranges compatible?

A: Yes. The original component operates from -55°C to 105°C, while both substitutes operate from -55°C to 125°C. The extended upper temperature limit of the substitutes provides additional thermal margin without creating compatibility issues.
