ICA-624-SST Equivalent & Substitute Parts Reference

Part Overview

The ICA-624-SST is a 24-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications requiring gold-plated beryllium copper contacts. This component is classified as an active product with full RoHS3 compliance and is suitable for applications operating across the -55°C to 125°C temperature range. The socket features a 0.6" row spacing with 0.100" pitch mating contacts and tin-plated brass posts for solder termination.

Equivalent and substitute parts are identified when design requirements, supply chain constraints, or manufacturing discontinuations necessitate component alternatives that maintain functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICA-624-SST are classified based on strict adherence to the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Number of positions: 24 (2 x 12)
• Row spacing: 0.6" (15.24mm)
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Contact material - Mating: Beryllium Copper
• Material Flammability Rating: UL94 V-0

Direct Substitutes maintain all primary compatibility criteria with identical or equivalent electrical performance characteristics. These parts are interchangeable in applications where the original ICA-624-SST specification is called out.

Similar Substitutes maintain all primary compatibility criteria but may differ in secondary parameters such as contact finish material, post finish composition, or RoHS compliance status. These parts are suitable for applications where the specific secondary parameter difference does not impact circuit performance or regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Fully Compatible):

The parts 110-41-624-41-001000 (Mill-Max Manufacturing Corp.) and 24-6518-10 (Aries Electronics) are direct substitutes for the ICA-624-SST. Both maintain identical primary compatibility parameters, including 24-position DIP configuration, 0.6" row spacing, 0.100" pitch, beryllium copper mating contacts with gold finish, and UL94 V-0 flammability rating. Both are RoHS3 compliant and suitable for applications requiring the full -55°C to 125°C operating temperature range. These parts provide higher current ratings (3 A versus 1 A) and enhanced post finish thickness (200.0µin), making them suitable for applications with increased current demands.

Similar Substitute (Conditional Compatibility):

The part AR 24-HZL-TT (Assmann WSW Components) is a similar substitute with the following distinctions: mating contact finish is tin rather than gold, and the operating temperature range is limited to -40°C to 105°C. This part is suitable for applications where the reduced temperature range is acceptable and where tin-plated contacts meet circuit requirements. The part maintains RoHS3 compliance and UL94 V-0 flammability rating. Contact resistance is superior at 4mOhm compared to the main part specification of 10mOhm.

Non-Recommended Substitute:

The part 110-91-624-41-001000 (Mill-Max Manufacturing Corp.) is classified as a similar substitute but is not recommended for new designs. This part is RoHS non-compliant, which disqualifies it from applications subject to RoHS3 regulatory requirements. The post finish composition (Tin-Lead) indicates legacy manufacturing processes. This part is suitable only for legacy system maintenance or applications where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can I use 110-41-624-41-001000 as a direct replacement for ICA-624-SST in my PCB design?

A: Yes. The 110-41-624-41-001000 maintains all critical compatibility parameters: 24-position DIP configuration, 0.6" row spacing, 0.100" pitch, beryllium copper mating contacts with gold finish, and identical operating temperature range (-55°C to 125°C). Both are RoHS3 compliant. The footprint and electrical characteristics are identical. No PCB redesign is required.

Q: What is the difference between the gold-plated and tin-plated versions?

A: The ICA-624-SST and most direct substitutes feature gold-plated mating contacts (10.0µin thickness), which provide superior corrosion resistance and lower contact resistance over extended service life. The AR 24-HZL-TT features tin-plated mating contacts, which are suitable for applications with shorter service life or lower environmental stress. Gold plating is preferred for high-reliability applications and extended storage periods.

Q: Why does the 24-6518-10 not specify an operating temperature range?

A: The operating temperature range is not provided in the available technical documentation for the 24-6518-10. When this parameter is not specified by the manufacturer, the part should be evaluated against application requirements through direct consultation with Aries Electronics or through independent testing if the application requires operation outside standard industrial temperature ranges (-40°C to 85°C).

Q: Is the 110-91-624-41-001000 suitable for new product designs?

A: No. The 110-91-624-41-001000 is RoHS non-compliant and uses Tin-Lead post finish, indicating legacy manufacturing. This part is suitable only for maintenance of existing systems or applications where RoHS compliance is not required. For new designs, use 110-41-624-41-001000 or 24-6518-10, both of which are RoHS3 compliant.

Q: What does the higher current rating (3 A) on substitute parts mean for my application?

A: The substitute parts 110-41-624-41-001000, 24-6518-10, and AR 24-HZL-TT are rated for 3 A per contact, compared to 1 A for the ICA-624-SST. This higher rating indicates enhanced current-carrying capacity and does not require any design changes. If your application requires only 1 A, any of these substitutes will operate safely with additional margin. If your application requires higher current, the substitutes provide the necessary capacity.

Q: Are all these parts available in the same packaging?

A: Yes. All listed parts are supplied in tube packaging, consistent with the ICA-624-SST. Tube packaging is standard for DIP socket components and ensures proper component protection during storage and handling.

Q: What is the significance of contact resistance specifications?

A: Contact resistance directly affects signal integrity and power dissipation in the socket. The ICA-624-SST specifies 10mOhm contact resistance. The 110-41-624-41-001000 and 24-6518-10 maintain this specification. The AR 24-HZL-TT provides superior contact resistance at 4mOhm, which reduces voltage drop and heat generation. For applications with tight power budgets or high-frequency signals, the lower contact resistance of the AR 24-HZL-TT may provide performance advantages.
