Amphenol ICC 94265-044 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 94265-044 is an active rectangular connector header designed for through-hole board-to-board or cable applications. This 44-position, 2-row connector operates at 2A current and 200V voltage ratings with a 0.079" (2.00mm) pitch configuration. The connector features gold-plated square contacts, unshrouded design, and push-pull fastening. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 94265-044 must maintain compatibility across the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — determines physical alignment and mating compatibility
• Number of Positions: 44 — ensures equivalent contact count
• Number of Rows: 2 — maintains row configuration
• Row Spacing - Mating: 0.079" (2.00mm) — preserves inter-row distance
• Connector Type: Header — functional classification
• Contact Type: Male Pin — gender compatibility
• Mounting Type: Through Hole — PCB assembly method
• Termination: Solder — connection method
• Fastening Type: Push-Pull — mechanical engagement mechanism
• Contact Shape: Square — contact geometry
• Insulation Material: Plastic — housing material category

The Samtec Inc. MTMM-122-06-T-D-070 meets these core substitution criteria. Variations in contact finish material (tin vs. gold), contact length specifications, and operating temperature range represent acceptable engineering trade-offs within the rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

The Samtec Inc. MTMM-122-06-T-D-070 serves as a direct substitute for the 94265-044 based on matching core electrical and mechanical parameters. Both connectors maintain identical pitch, position count, row configuration, and through-hole solder termination specifications.

The MTMM-122-06-T-D-070 offers ROHS3 compliance, whereas the 94265-044 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements. The substitute part's current rating of 3A exceeds the 2A specification of the main part, providing additional capacity margin. The Samtec connector features Liquid Crystal Polymer (LCP) insulation material and phosphor bronze contacts with tin finish, compared to the plastic insulation and gold-plated copper alloy contacts of the Amphenol part. Both connectors maintain UL94 V-0 flammability certification.

Selection between these parts should be based on regulatory compliance requirements, material specifications, and contact finish preferences for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the MTMM-122-06-T-D-070 directly replace the 94265-044 in existing designs?

A: Yes, provided the application does not require the specific contact finish or material properties of the original part. Both connectors share identical pitch (0.079"), position count (44), row configuration (2), and through-hole solder termination. Physical and electrical compatibility is maintained.

Q: What is the significance of the contact finish difference (gold vs. tin)?

A: Contact finish affects corrosion resistance and mating force characteristics. Gold provides superior corrosion resistance and lower contact resistance over extended service life. Tin finish is cost-effective and suitable for standard industrial applications with adequate environmental protection.

Q: Does the higher current rating of the MTMM-122-06-T-D-070 (3A vs. 2A) affect compatibility?

A: No. A substitute part with higher current capacity is acceptable for applications designed for the lower rating. The substitute can safely handle the original design's current requirements with additional margin.

Q: Why is RoHS compliance status different between the two parts?

A: RoHS compliance depends on material composition and manufacturing processes. The MTMM-122-06-T-D-070 meets ROHS3 standards, making it suitable for applications requiring RoHS-compliant components. The 94265-044 does not meet these standards and should be selected only when RoHS compliance is not a requirement.

Q: Are there differences in insulation material properties?

A: The 94265-044 uses plastic insulation, while the MTMM-122-06-T-D-070 uses Liquid Crystal Polymer (LCP). LCP offers superior thermal stability, dimensional consistency, and chemical resistance compared to standard plastic, making it suitable for demanding environmental conditions.

Q: What packaging differences exist between these parts?

A: The 94265-044 is supplied in bag packaging, while the MTMM-122-06-T-D-070 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility but may influence handling and storage procedures.
