Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICO-628-AGT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 28 (2 x 14)
• Row Spacing: 0.6" (15.24mm)
• Pitch - Mating: 0.100" (2.54mm)
• Contact Finish - Mating: Gold
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 125°C

Allowable Variations:

• Contact Finish - Post: Tin or Tin-Lead (both acceptable for solder termination)
• Contact Finish Thickness - Post: Variations permitted (10.0µin to 200.0µin)
• Contact Material - Post: Brass or Brass Alloy (both acceptable)
• Housing Material: Polyester or PCT-based polymers (both acceptable)
• Current Rating: Substitute may exceed main part rating (1A minimum required)
• Contact Resistance: Variations permitted if not specified as critical
• RoHS Compliance: Not a substitution barrier for functional equivalence

The identified substitute part 111-93-628-41-001000 (Mill-Max Manufacturing Corp.) meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (ICO-628-AGT): The ICO-628-AGT remains the primary choice for applications requiring ROHS3 compliance certification. This part carries active product status with confirmed UL94 V-0 flammability rating and specified contact resistance of 10mOhm. Current inventory of 667 pieces supports standard procurement timelines.

Substitute Selection (111-93-628-41-001000): The Mill-Max 111-93-628-41-001000 is functionally equivalent for applications where RoHS3 compliance is not a contractual or regulatory requirement. This substitute provides higher current rating capacity (3A versus 1A) and greater post contact finish thickness (200.0µin versus 10.0µin), which may offer enhanced durability in high-cycle insertion applications. Inventory availability of 1277 pieces provides extended supply security. The Tin-Lead post finish is compatible with standard solder reflow processes.

Compliance Considerations: Selection between these parts must account for end-product regulatory requirements. The ICO-628-AGT is specified for applications requiring documented RoHS3 compliance. The Mill-Max substitute is suitable for applications where RoHS compliance is not mandated or where RoHS non-compliance is acceptable.

Mechanical Compatibility: Both parts are mechanically interchangeable at the PCB level. Identical row spacing (0.6"), pitch (0.100"), and position count (28) ensure direct footprint compatibility. No PCB redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 111-93-628-41-001000 be used as a direct replacement for the Samtec ICO-628-AGT?

A: Yes, for applications where RoHS3 compliance is not required. Both parts share identical mechanical footprints, pin counts, row spacing, and mating contact specifications. The substitute provides equivalent electrical performance with higher current rating capacity.

Q: What is the significance of the different post contact finishes (Tin versus Tin-Lead)?

A: Both finishes are compatible with standard solder reflow assembly processes. Tin-Lead finish (Mill-Max) provides thicker coating (200.0µin) compared to Tin finish (Samtec, 10.0µin), which may extend contact life in high-insertion-cycle applications. Selection depends on assembly process compatibility and end-product requirements.

Q: Are these parts physically interchangeable on the PCB?

A: Yes. Both parts have identical row spacing (0.6"), mating pitch (0.100"), and 28-position configuration. No PCB layout modifications are required when substituting between these parts.

Q: What is the difference in current rating between these parts?

A: The Samtec ICO-628-AGT is rated for 1A, while the Mill-Max 111-93-628-41-001000 is rated for 3A. For applications requiring current handling above 1A, the Mill-Max substitute provides additional capacity margin.

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

A: The Samtec ICO-628-AGT carries ROHS3 compliance certification. The Mill-Max substitute is RoHS non-compliant and should not be used in applications with RoHS compliance requirements.

Q: Is contact resistance specified for the Mill-Max substitute?

A: No. The Mill-Max 111-93-628-41-001000 does not provide contact resistance specification in the available data. The Samtec ICO-628-AGT specifies 10mOhm contact resistance. Applications with critical contact resistance requirements should use the Samtec part.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent environmental conditions.

Q: Are both parts currently in production?

A: Yes. Both the Samtec ICO-628-AGT and Mill-Max 111-93-628-41-001000 carry active product status with confirmed current inventory availability.
