ICA-314-STT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-314-STT is a 14-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring 0.3" (7.62mm) row spacing. This socket features tin-plated beryllium copper mating contacts and brass posts, rated for 1 A continuous current with a contact resistance of 10 mOhm. The component operates across the temperature range of -55°C to 105°C and maintains UL94 V-0 flammability compliance.

Equivalent and substitute parts are identified to address inventory availability, extended lead times, or specific application requirements while maintaining electrical and mechanical compatibility within the DIP socket category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICA-314-STT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Type: DIP with 0.3" (7.62mm) row spacing
• Number of Positions: 14 (2 x 7)
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Contact Material - Mating: Beryllium Copper
• Termination: Solder
• Features: Open Frame

Allowable Variation Parameters:

• Contact Finish - Mating: Tin or Tin-Lead
• Contact Material - Post: Brass or Brass Alloy
• Operating Temperature Range: Equal to or exceeding -55°C to 105°C
• Current Rating: Equal to or exceeding 1 A
• Contact Resistance: Equal to or lower than 10 mOhm
• Housing Material: Polyester-based compounds (Polyester, Glass Filled; Polycyclohexylenedimethylene Terephthalate)

The substitute part 110-99-314-41-001000 (Mill-Max Manufacturing Corp.) meets all mandatory parameters and exceeds performance specifications in current rating (3 A vs. 1 A) and operating temperature range (-55°C to 125°C vs. -55°C to 105°C).

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ICA-314-STT (Samtec Inc.)

The ICA-314-STT remains the specified component when original part availability is confirmed and inventory meets project timelines. This part is Active status with 799 units in stock and carries UL94 V-0 flammability certification.

Substitute Selection: 110-99-314-41-001000 (Mill-Max Manufacturing Corp.)

The 110-99-314-41-001000 is a qualified substitute when the ICA-314-STT is unavailable or subject to extended lead times. This part is Active status with 2276 units in stock. The substitute provides enhanced electrical performance (3 A current rating vs. 1 A) and extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C), making it suitable for applications requiring higher thermal or current margins.

Both parts are RoHS non-compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, indicating equivalent regulatory treatment for export and tariff purposes.

The contact finish difference (Tin vs. Tin-Lead) does not affect mechanical or electrical compatibility in standard through-hole soldering applications. The Tin-Lead finish on the Mill-Max substitute provides established solderability characteristics consistent with legacy PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 110-99-314-41-001000 be used as a direct replacement for the ICA-314-STT on existing PCBs?

A: Yes. Both parts share identical pitch specifications (0.100" mating and post), identical 14-position DIP configuration with 0.3" row spacing, and identical through-hole termination. The physical footprint and electrical interface are compatible. No PCB redesign is required.

Q: What is the significance of the Tin-Lead finish on the Mill-Max part versus the Tin finish on the Samtec part?

A: Both finishes are acceptable for through-hole solder applications. Tin-Lead (Pb/Sn) provides established solderability and is commonly used in legacy designs. Tin provides lead-free compliance for RoHS-compliant applications. For this product category, both finishes deliver equivalent contact performance and reliability. The choice depends on your assembly process and compliance requirements.

Q: Does the higher current rating (3 A) of the Mill-Max part affect compatibility?

A: No. A higher current rating indicates the substitute can safely handle greater current loads without degradation. If your application requires only 1 A, the 3 A rating of the Mill-Max part provides additional design margin and does not compromise compatibility or performance.

Q: Are there any temperature-related compatibility concerns?

A: No. The Mill-Max substitute operates from -55°C to 125°C, which encompasses the -55°C to 105°C range of the Samtec part. The extended upper temperature limit provides additional thermal margin and does not introduce compatibility issues.

Q: What is the difference between Brass and Brass Alloy post materials?

A: Both are brass-based materials suitable for through-hole post applications. Brass Alloy may contain additional elements for enhanced mechanical or electrical properties. For DIP socket applications, both materials deliver equivalent performance in contact retention, solderability, and electrical conductivity.

Q: Are both parts subject to the same regulatory classifications?

A: Yes. Both the ICA-314-STT and 110-99-314-41-001000 share identical ECCN (EAR99), HTSUS (8536.69.4040), and RoHS non-compliant status. They are treated equivalently for export control and tariff purposes.

Q: What is the Moisture Sensitivity Level (MSL) difference between the parts?

A: The Samtec part lists MSL as Not Applicable, while the Mill-Max part specifies MSL 1 (Unlimited). MSL 1 indicates the component has no moisture sensitivity restrictions and requires no special storage or handling precautions. This difference does not affect compatibility or performance.

Q: Can I mix Samtec and Mill-Max sockets on the same PCB?

A: Yes. Both parts are mechanically and electrically compatible. Mixing manufacturers on the same board is acceptable from a functional standpoint. However, standard procurement and quality practices typically favor consistency within a single design to simplify inventory management and traceability.
