Engineering Selection Recommendations
ROHS3 Compliant Substitutes (Recommended for New Designs):
The following Mill-Max parts maintain ROHS3 compliance matching the ICO-314-SST and are suitable for direct substitution in applications where regulatory compliance is required:
- 110-13-314-41-001000 and 110-13-314-41-801000: Gold post finish, 3 A current rating
- 110-41-314-41-001000: Tin post finish, 3 A current rating
- 110-43-314-41-001000, 110-43-314-41-605000, and 110-43-314-41-801000: Tin post finish, 3 A current rating
- 110-44-314-41-001000: Tin mating finish, tin post finish, 3 A current rating
Non-Compliant Substitutes (Legacy Applications Only):
The following parts contain Tin-Lead post finishes and are RoHS non-compliant:
- 110-91-314-41-001000
- 110-93-314-41-001000
- 110-93-314-41-605000
These parts are suitable only for legacy systems or applications where RoHS compliance is not required.
Current Rating Consideration:
All Mill-Max substitutes provide 3 A current rating, exceeding the 1 A specification of the ICO-314-SST. This higher rating provides additional design margin and does not restrict compatibility.
Frequently Asked Questions (FAQ)
Q: Can Mill-Max 110-series sockets directly replace the Samtec ICO-314-SST?
A: Yes. All listed Mill-Max parts maintain the critical 14-position DIP configuration, 0.100" mating pitch, 0.3" row spacing, and through-hole solder termination. Mechanical and electrical compatibility is preserved across all ROHS3-compliant variants.
Q: What is the difference between gold and tin mating contact finishes?
A: Both finishes are compatible with standard DIP integrated circuits. Gold provides enhanced corrosion resistance and lower contact resistance. Tin is suitable for standard applications. Selection depends on environmental exposure and contact resistance requirements.
Q: Are the post finish variations (Tin, Gold, Tin-Lead) interchangeable?
A: Yes, for mechanical and electrical compatibility. Post finish affects solder joint formation and long-term reliability in specific environments. Tin and gold post finishes are ROHS3 compliant. Tin-Lead finishes are non-compliant with current regulations.
Q: What does the decoupling capacitor feature indicate?
A: Parts 110-13-314-41-801000 and 110-43-314-41-801000 include integrated decoupling capacitor functionality. This feature does not affect basic socket compatibility but provides additional circuit noise filtering when utilized.
Q: Why do some substitutes have higher current ratings?
A: Mill-Max parts are rated for 3 A versus the ICO-314-SST's 1 A rating. Higher current capacity indicates superior contact design and material selection. This does not restrict compatibility and provides additional design margin for applications requiring higher current handling.
Q: Which substitute should I select for new designs?
A: For new designs requiring regulatory compliance, select from ROHS3-compliant options: 110-13-314-41-001000, 110-41-314-41-001000, 110-43-314-41-001000, or 110-44-314-41-001000. Selection among these depends on specific post finish and contact material requirements for your application.
Q: Is inventory availability a factor in substitution?
A: Inventory levels are provided for reference. Mill-Max parts show higher stock levels across most variants, with 110-41-314-41-001000 offering the highest availability at 2438 pieces.
