Substitute Part Grouping Explanation

Substitution eligibility for the ICO-648-SGT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

  • Number of Positions: 48 (2 x 24)
  • 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 minimum
  • Termination: Solder

Allowable Variations:

  • Contact Finish Thickness - Post: May vary within industry standards
  • Contact Material - Post: Brass or Brass Alloy acceptable
  • Housing Material: Polyester or equivalent thermoplastic polymers
  • Current Rating: Substitute may exceed original specification
  • Contact Resistance: Substitute performance acceptable if not specified as limiting factor

The substitute part 110-93-648-41-001000 from Mill-Max Manufacturing Corp. satisfies all mandatory matching parameters and is therefore classified as a direct equivalent.

Engineering Selection Recommendations

ICO-648-SGT Selection Criteria:

  • Active product status with established supply chain
  • ROHS3 compliance required for regulated applications
  • Specified contact resistance of 10mOhm meets defined electrical requirements
  • Glass-filled polyester housing provides enhanced mechanical stability

110-93-648-41-001000 Selection Criteria:

  • Higher current rating (3 A) accommodates applications exceeding 1 A requirements
  • Increased post contact finish thickness (200.0µin) provides extended service life in high-cycle insertion applications
  • RoHS non-compliance restricts use in regulated markets and restricted substance environments
  • Tin-Lead post finish may require process compatibility assessment in lead-free manufacturing environments
  • Higher inventory availability (1,244 units) supports immediate procurement needs

Compliance Considerations: Selection between these parts must account for regulatory requirements. Applications subject to ROHS3 mandates require the ICO-648-SGT. Applications operating in unrestricted markets may utilize the 110-93-648-41-001000 based on performance and availability requirements.

Frequently Asked Questions (FAQ)

Q: Can the 110-93-648-41-001000 directly replace the ICO-648-SGT in all applications?

A: Direct mechanical and electrical replacement is supported for applications not subject to ROHS3 compliance requirements. The substitute part matches all critical mating parameters, row spacing, pitch, and operating temperature range. However, the RoHS non-compliance status of the Mill-Max part restricts its use in regulated applications.

Q: What is the significance of the different post contact finish specifications?

A: The ICO-648-SGT specifies 10.0µin tin finish on brass posts, while the 110-93-648-41-001000 specifies 200.0µin tin-lead finish on brass alloy posts. The thicker finish on the substitute part provides enhanced durability in high-cycle insertion environments. Both finishes are suitable for solder termination. The tin-lead composition of the substitute may require compatibility assessment in lead-free manufacturing processes.

Q: Are the housing materials functionally equivalent?

A: Yes. The ICO-648-SGT uses glass-filled polyester, while the 110-93-648-41-001000 uses polycyclohexylenedimethylene terephthalate (PCT) polyester. Both materials provide adequate mechanical support, thermal stability across the -55°C to 125°C operating range, and UL94 V-0 or equivalent flammability ratings. Material selection does not affect socket functionality or package compatibility.

Q: Why does the substitute part have a higher current rating?

A: The 110-93-648-41-001000 is rated for 3 A compared to the ICO-648-SGT's 1 A rating. This reflects design differences in contact geometry and material composition. The higher rating does not affect compatibility; applications requiring only 1 A operation remain fully supported by the substitute part.

Q: What inventory considerations apply to these parts?

A: The ICO-648-SGT maintains 950 units in stock, while the 110-93-648-41-001000 has 1,244 units available. Both parts are classified as new original stock. Procurement decisions should account for lead time requirements and supply chain stability for long-term production planning.

Q: Are there any electrical performance differences between these sockets?

A: The ICO-648-SGT specifies 10mOhm contact resistance. The 110-93-648-41-001000 does not provide a specified contact resistance value. Both parts utilize beryllium copper mating contacts with gold finish, ensuring equivalent electrical performance for standard DIP package insertion applications. Contact resistance differences, if any, fall within acceptable tolerances for this socket category.
