ICA-624-STT DIP Socket Equivalent & Substitute Parts

Part Overview

The ICA-624-STT is a 24-position DIP socket manufactured by Samtec Inc., designed for through-hole mounting applications. This socket features a 0.6" (15.24mm) row spacing with 0.100" (2.54mm) pitch, tin-plated beryllium copper mating contacts, and brass post contacts. The component is classified as Active product status with ROHS3 compliance and UL94 V-0 flammability rating. Equivalent and substitute parts are identified for applications requiring alternative sourcing, inventory availability, or specific performance characteristics within the defined electrical and mechanical parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICA-624-STT are classified based on strict alignment with the following critical parameters: 24-position DIP configuration, 0.6" row spacing, 0.100" pitch (both mating and post), through-hole mounting, and solder termination. All substitute candidates maintain beryllium copper mating contacts and brass-based post contacts with tin contact finish on mating surfaces.

Direct Equivalents share identical mechanical and electrical specifications within acceptable tolerance ranges:

• 110-44-624-41-001000 (Mill-Max Manufacturing Corp.)
• AR 24-HZL-TT (Assmann WSW Components)

Similar Substitutes maintain core mechanical compatibility but differ in specific electrical or material characteristics:

• 110-99-624-41-001000 (Mill-Max Manufacturing Corp.) — Tin-Lead finish variant

Substitution eligibility is determined by: (1) matching position count and row spacing, (2) identical pitch specifications, (3) compatible contact materials, (4) through-hole mounting configuration, and (5) solder termination method.

Parameter Comparison

Engineering Selection Recommendations

110-44-624-41-001000 (Mill-Max Manufacturing Corp.) is a direct equivalent suitable for applications requiring ROHS3 compliance. This part maintains identical mechanical configuration and contact materials. The higher current rating (3 A versus 1 A) and extended operating temperature range (-55°C to 125°C) provide additional performance margin. ROHS3 compliance aligns with the main part specification.

AR 24-HZL-TT (Assmann WSW Components) is a direct equivalent with ROHS3 compliance and UL94 V-0 flammability rating matching the main part. The beryllium copper post contacts provide superior contact resistance (4mOhm) compared to the main part (10mOhm). Operating temperature range is -40°C to 105°C, which covers the main part specification. Current rating of 3 A exceeds the main part requirement.

110-99-624-41-001000 (Mill-Max Manufacturing Corp.) is a similar substitute with tin-lead contact finish on both mating and post surfaces. This part is RoHS non-compliant and should be selected only for applications where tin-lead finish is required and RoHS compliance is not mandated. Mechanical configuration and position count remain identical. Current rating and operating temperature range match the direct equivalents.

All three substitute parts maintain the 24-position DIP configuration, 0.6" row spacing, and 0.100" pitch required for mechanical and electrical compatibility with the ICA-624-STT.

Frequently Asked Questions (FAQ)

Q: Can 110-44-624-41-001000 be used as a direct replacement for ICA-624-STT?

A: Yes. Both parts share identical mechanical configuration (24-position DIP, 0.6" row spacing, 0.100" pitch), contact materials (beryllium copper mating, brass post), and through-hole solder termination. Both are ROHS3 compliant. The Mill-Max part offers higher current rating (3 A) and extended temperature range (-55°C to 125°C).

Q: What is the difference between AR 24-HZL-TT and 110-44-624-41-001000?

A: Both are direct equivalents with identical position count and pitch. Key differences: AR 24-HZL-TT uses beryllium copper post contacts (versus brass alloy in Mill-Max), provides lower contact resistance (4mOhm), and carries UL94 V-0 flammability rating. Operating temperature range for AR 24-HZL-TT is -40°C to 105°C.

Q: When should 110-99-624-41-001000 be selected?

A: This part is suitable only when tin-lead contact finish is specifically required and RoHS compliance is not a design constraint. Mechanical compatibility is identical to other substitutes. The part is RoHS non-compliant due to tin-lead finish composition.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts maintain 24-position DIP configuration with 0.6" row spacing and 0.100" pitch on both mating and post contacts. PCB footprint compatibility is assured across all listed substitutes.

Q: What is the significance of contact resistance differences?

A: Contact resistance values (10mOhm for ICA-624-STT, 4mOhm for AR 24-HZL-TT) indicate electrical performance characteristics. Lower contact resistance reduces voltage drop and heat generation. Both values are within acceptable ranges for standard DIP socket applications.

Q: Do all substitute parts meet the same compliance standards?

A: ICA-624-STT and direct equivalents (110-44-624-41-001000 and AR 24-HZL-TT) are ROHS3 compliant. The similar substitute 110-99-624-41-001000 is RoHS non-compliant due to tin-lead finish. UL94 V-0 flammability rating is specified for ICA-624-STT and AR 24-HZL-TT.

Q: What is the inventory availability for each part?

A: ICA-624-STT: 1040 pcs; 110-44-624-41-001000: 2240 pcs; AR 24-HZL-TT: 1576 pcs; 110-99-624-41-001000: 1073 pcs. All parts are listed as new original stock.
