ICO-624-STT Equivalent & Substitute Parts

Part Overview

The ICO-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 contacts, tin-plated beryllium copper mating contacts, and brass posts. The product is currently active in production with 1070 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-624-STT is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Positions: 24 (2 x 12)
• Type: DIP with 0.6" (15.24mm) row spacing
• Pitch - Mating: 0.100" (2.54mm)
• Pitch - Post: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Material - Mating: Beryllium Copper
• Contact Material - Post: Brass or Brass Alloy

Secondary Compatibility Parameters:

• Operating Temperature Range
• Current Rating
• Contact Finish specifications
• RoHS compliance status

The substitute part 110-99-624-41-001000 (Mill-Max Manufacturing Corp.) meets all primary matching criteria and is therefore classified as a direct functional equivalent for the ICO-624-STT.

Parameter Comparison

Engineering Selection Recommendations

ICO-624-STT (Samtec Inc.) is the primary specification. This part is ROHS3 compliant and suitable for applications requiring RoHS compliance. The operating temperature range of -55°C to 105°C and current rating of 1 A define the baseline performance envelope.

110-99-624-41-001000 (Mill-Max Manufacturing Corp.) serves as a functional substitute with the following considerations:

• Mechanical Compatibility: Identical pin count (24), pitch (0.100"), and row spacing (0.6") ensure direct PCB footprint compatibility.
• Electrical Performance: Higher current rating (3 A) and extended operating temperature range (-55°C to 125°C) provide expanded operational capability.
• Contact Finish Difference: Tin-Lead finish on the Mill-Max part differs from the Samtec tin finish. Both finishes are suitable for solder termination applications.
• Compliance Status: The Mill-Max part is RoHS non-compliant. Selection of this substitute requires confirmation that the application does not mandate RoHS compliance.
• Product Status: Both parts are active in production.

Selection between these parts depends on compliance requirements and operational temperature/current specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 110-99-624-41-001000 be used as a direct replacement for the ICO-624-STT on existing PCBs?

A: Yes. Both parts share identical pin counts (24), pitch spacing (0.100"), and row spacing (0.6"), ensuring mechanical and electrical compatibility at the PCB level. No PCB redesign is required.

Q: What is the primary difference between these two socket types?

A: The primary differences are contact finish (Tin vs. Tin-Lead), current rating (1 A vs. 3 A), operating temperature range (-55°C to 105°C vs. -55°C to 125°C), and RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Q: Which part should be selected for RoHS-compliant applications?

A: The ICO-624-STT (Samtec) is ROHS3 compliant and must be used for applications requiring RoHS compliance. The 110-99-624-41-001000 is RoHS non-compliant and is not suitable for such applications.

Q: Does the higher current rating of the Mill-Max part affect compatibility?

A: No. A higher current rating indicates greater capability and does not affect compatibility. The substitute part can safely handle applications designed for the 1 A rating of the primary part.

Q: Are there any thermal considerations when selecting between these parts?

A: The Mill-Max part operates to 125°C compared to 105°C for the Samtec part. For applications operating near or above 105°C, the Mill-Max part provides extended thermal capability. For applications below 105°C, both parts are suitable.

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

A: Tin-Lead finish is a traditional plating specification that provides reliable solder wetting and contact performance. The difference from pure Tin finish does not affect mechanical or electrical compatibility in standard through-hole solder applications.
