Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 88921-101 is determined by the following critical parameters:

• Position Count & Pitch: The substitute must maintain 24 positions at 0.079" (2.00mm) pitch to ensure PCB footprint compatibility
• Connector Configuration: 4-row arrangement with male pins through-hole mounting
• Termination Method: Press-fit termination required for mechanical compatibility
• Contact Material & Finish: Gold-plated contacts for electrical performance and corrosion resistance
• Electrical Rating: Current capacity and operating temperature range must meet or exceed application requirements
• Compliance Status: RoHS compliance and regulatory certifications (UL94 V-0, REACH Unaffected, EAR99)

The 3M MP2-H024-41P1-S-LR qualifies as a direct substitute based on matching all critical mechanical and electrical parameters while offering improved product status and compliance profile.

Parameter Comparison

Engineering Selection Recommendations

The 3M MP2-H024-41P1-S-LR is the qualified substitute for the obsolete Amphenol ICC 88921-101. Selection is based on the following engineering criteria:

Mechanical Compatibility: Both connectors share identical position count (24), pitch (0.079"/2.00mm), row configuration (4), and through-hole press-fit termination, ensuring direct PCB footprint compatibility without layout modifications.

Electrical Performance: The 3M substitute provides higher current rating (1.5A vs. 1A), supporting applications with increased power delivery requirements. The operating temperature range of -55°C to 105°C covers the majority of industrial applications, with the Amphenol part's extended upper limit (125°C) applicable only to specialized high-temperature environments.

Regulatory Compliance: The 3M MP2-H024-41P1-S-LR holds active product status with RoHS compliance, addressing modern supply chain and environmental requirements. Both parts maintain UL94 V-0 flammability certification and EAR99 export classification.

Product Availability: The substitute is currently in active production with documented inventory (684 pcs), ensuring long-term supply continuity compared to the obsolete Amphenol part.

Frequently Asked Questions (FAQ)

Q: Will the 3M MP2-H024-41P1-S-LR fit the existing PCB designed for the Amphenol ICC 88921-101?

A: Yes. Both connectors maintain identical 24-position configuration, 0.079" (2.00mm) pitch, and 4-row arrangement. The through-hole press-fit termination is mechanically compatible without PCB redesign.

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

A: The Amphenol ICC 88921-101 is rated for 1A, while the 3M MP2-H024-41P1-S-LR is rated for 1.5A. The substitute supports higher current applications. If your design operates at or below 1A, both connectors are functionally equivalent for this parameter.

Q: Does the operating temperature range difference affect compatibility?

A: The Amphenol part operates from -55°C to 125°C, while the 3M substitute operates from -55°C to 105°C. For applications requiring sustained operation above 105°C, the original Amphenol specification must be maintained. For standard industrial temperature ranges (-55°C to 105°C), the substitute is fully compatible.

Q: Is the 3M substitute RoHS compliant?

A: Yes. The 3M MP2-H024-41P1-S-LR is RoHS compliant, meeting current environmental and regulatory requirements. The original Amphenol ICC 88921-101 is RoHS non-compliant.

Q: Are there any differences in contact finish between these connectors?

A: Both connectors feature gold-plated contacts. The Amphenol part specifies 30.0µin (0.76µm) thickness, while the 3M part specifies 3.00µin (0.076µm). Both thicknesses provide adequate corrosion resistance and electrical conductivity for standard applications.

Q: What packaging is available for the 3M substitute?

A: The 3M MP2-H024-41P1-S-LR is supplied in bulk packaging, suitable for production assembly and repair operations.
