ICA-314-SGT 14-Position DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-314-SGT is a 14-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting of dual inline package integrated circuits. This connector features gold-plated beryllium copper mating contacts with tin-plated brass posts, operating across -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting identical or superior electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ICA-314-SGT is determined by strict equivalence across the following critical parameters:

14-position configuration with 2 x 7 arrangement
0.3" (7.62mm) row spacing
0.100" (2.54mm) mating and post pitch
Gold-plated mating contacts with beryllium copper material
Through-hole solder termination
0.125" (3.18mm) post length
Operating temperature range of -55°C to 125°C minimum

Substitute parts must maintain these specifications without deviation. Secondary parameters including contact finish thickness, post material composition, current rating, and compliance certifications may vary within acceptable engineering tolerances while preserving functional interchangeability.

Engineering Selection Recommendations

110-43-314-41-001000 (Mill-Max Manufacturing Corp.) is the primary direct substitute. This part maintains full electrical and mechanical equivalence with the ICA-314-SGT, including identical operating temperature range (-55°C to 125°C), ROHS3 compliance, and all critical mating specifications. The higher current rating (3 A versus 1 A) provides additional design margin without compromising compatibility. This part is currently in active production status with 797 units in stock.

110-93-314-41-001000 (Mill-Max Manufacturing Corp.) is functionally equivalent across all critical mechanical and electrical parameters. However, this part carries RoHS non-compliant status, making it unsuitable for applications requiring RoHS certification. Selection of this part should be limited to legacy systems or applications with explicit non-compliance allowances. Current production status is active with 1764 units available.

4-1571552-2 (TE Connectivity AMP Connectors) meets all mechanical substitution criteria but carries obsolete product status. The operating temperature range is limited to -55°C to 105°C, which is 20°C below the primary part specification. This temperature limitation may restrict use in high-temperature applications. This part should be considered only when supply of active alternatives is exhausted and application thermal requirements do not exceed 105°C.

Frequently Asked Questions (FAQ)

Q: Can 110-43-314-41-001000 be used as a direct replacement for ICA-314-SGT without PCB modifications?

A: Yes. Both parts share identical pitch specifications (0.100" mating and post), 0.3" row spacing, 0.125" post length, and through-hole solder termination. No PCB layout changes are required.

Q: What is the significance of the higher current rating in the Mill-Max substitutes?

A: The 110-43-314-41-001000 and 110-93-314-41-001000 are rated for 3 A compared to the ICA-314-SGT's 1 A rating. This higher rating does not affect compatibility; it indicates the substitute can safely handle greater current loads without performance degradation.

Q: Why is the 4-1571552-2 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While the part may remain available through inventory channels, future procurement cannot be guaranteed. This part should be used only when active alternatives are unavailable.

Q: Does the 110-93-314-41-001000 RoHS non-compliance affect electrical performance?

A: RoHS non-compliance relates to material composition restrictions, not electrical performance. The part functions identically to compliant alternatives. However, regulatory requirements in target markets may prohibit its use in end applications.

Q: Are there differences in contact finish thickness between these parts?

A: Yes. The ICA-314-SGT specifies 30.0µin (0.76µm) gold on mating contacts, while the 4-1571552-2 specifies 20.0µin (0.51µm). Both thicknesses are within acceptable engineering tolerances for DIP socket applications and do not affect interchangeability.

Q: What is the maximum operating temperature for each substitute?

A: ICA-314-SGT, 110-43-314-41-001000, and 110-93-314-41-001000 all operate to 125°C. The 4-1571552-2 is limited to 105°C. Applications requiring operation above 105°C must use one of the 125°C-rated alternatives.
