TE Connectivity AMP Connectors 3-103336-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 3-103336-9 is an active rectangular connector header designed for through-hole mounting applications. This unshrouded, 7-position connector operates at 0.100" (2.54mm) pitch and supports board-to-board or cable interconnection with a rated current capacity of 3A. The connector features gold-plated mating contacts and tin-lead plated posts, with an operating temperature range of -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative manufacturer selections.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 3-103336-9 are identified based on strict equivalence of critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must align across all equivalent parts:

Critical Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 7
• Number of Rows: 1
• Mounting Type: Through Hole
• Shrouding: Unshrouded
• Style: Board to Board or Cable
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Color: Black
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The Molex 0022284074 connector meets all critical matching parameters and is classified as a direct substitute. Both connectors share identical pitch spacing, position count, mounting methodology, and environmental compliance ratings. Differences in contact post length, overall contact length, and insulation material composition do not preclude substitution when mechanical envelope constraints and electrical performance requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 3-103336-9 and Molex 0022284074 connectors are active products with confirmed RoHS compliance status. The TE Connectivity part carries RoHS Compliant certification, while the Molex substitute carries ROHS3 Compliant certification, indicating compliance with the most current regulatory requirements. Both parts maintain UL94 V-0 flammability ratings and unlimited moisture sensitivity levels (MSL 1), confirming suitability for general industrial and commercial applications without special handling requirements.

Selection between these parts should be based on:

Availability and Inventory: The Molex 0022284074 currently maintains higher inventory levels (1167 pieces) compared to the TE Connectivity part (797 pieces), providing supply chain flexibility.

Packaging Format: The TE Connectivity part is supplied in tray packaging, while the Molex substitute is supplied in bulk packaging. Packaging selection depends on assembly line requirements and component handling procedures.

Contact Post Specifications: The TE Connectivity part features 0.250" (6.35mm) contact post length with tin-lead plating, while the Molex substitute features 0.120" (3.05mm) contact post length with tin plating. These differences require verification against PCB design specifications and solder joint requirements.

Insulation Material: The TE Connectivity part uses thermoplastic insulation, while the Molex substitute uses polyamide (PA) nylon with glass filling. Both materials meet UL94 V-0 requirements and are suitable for the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022284074 be used as a direct replacement for the TE Connectivity 3-103336-9?

A: The Molex 0022284074 qualifies as a substitute part based on matching critical parameters including connector type, contact type, pitch spacing, position count, mounting type, and environmental compliance ratings. However, differences in contact post length (0.250" versus 0.120") and insulation material composition require verification against specific PCB design and assembly requirements before implementation.

Q: What are the key differences between these two connector models?

A: The primary differences are contact post length, overall contact length, insulation material composition, and packaging format. The TE Connectivity part features longer contact posts (0.250") with tin-lead plating, while the Molex part features shorter contact posts (0.120") with tin plating. The TE Connectivity part uses thermoplastic insulation, while the Molex part uses glass-filled polyamide. These differences do not affect mating interface compatibility but may impact PCB design and assembly considerations.

Q: Are both connectors suitable for the same applications?

A: Both connectors are designed for board-to-board or cable interconnection applications with identical pitch spacing and position configuration. The Molex part documentation identifies specific applications including automotive, general purpose, medical, and telecommunications. Application suitability depends on specific design requirements, environmental conditions, and regulatory compliance needs for the target application.

Q: What is the significance of the different RoHS compliance statuses?

A: The TE Connectivity part carries RoHS Compliant certification, while the Molex substitute carries ROHS3 Compliant certification. ROHS3 represents the most current regulatory standard and includes additional restricted substances beyond the original RoHS directive. Both certifications confirm compliance with hazardous substance restrictions, with ROHS3 providing compliance with the most stringent current requirements.

Q: How do the packaging differences affect component selection?

A: The TE Connectivity part is supplied in tray packaging, while the Molex substitute is supplied in bulk packaging. Tray packaging typically provides better component protection and organization for automated assembly processes, while bulk packaging may offer cost advantages for high-volume applications. Selection depends on assembly line capabilities and component handling procedures.

Q: Are the contact finish specifications compatible between these parts?

A: Both parts feature gold-plated mating contacts with identical mating contact length (0.320"). The TE Connectivity part uses tin-lead plating on posts, while the Molex part uses tin plating. Both finishes are suitable for solder joint formation, though tin-lead plating may provide different wetting characteristics compared to tin plating during reflow soldering processes.
