Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 207541-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Voltage Rating: 600V
• Current Rating: 7.5A
• Operating Temperature Range: -55°C ~ 130°C

Mechanical Compatibility Parameters:

• Number of Positions: 3
• Pitch - Mating: 0.197" (5.00mm)
• Mounting Type: Through Hole, Right Angle
• Contact Type: Male Pin
• Shrouding: Shrouded - 4 Wall
• Connector Type: Header
• Insulation Material: Polyamide (PA), Nylon
• Contact Material: Brass
• Contact Shape: Circular
• Fastening Type: Latch Holder
• Features: Mounting Flange

Contact Finish Parameters:

• Contact Finish - Mating: Gold
• Contact Finish Thickness - Mating: 30.0µin (0.76µm)
• Contact Finish Thickness - Post: 150.0µin (3.81µm)

The substitute part 207541-7 maintains full equivalence across all critical electrical and mechanical parameters. The primary distinction is product status: 207541-7 is active and RoHS3 compliant, whereas 207541-3 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 207541-7 is the direct functional equivalent and substitute for the obsolete 207541-3. Both components share identical electrical ratings (600V, 7.5A), mechanical configuration (3-position, 5.00mm pitch, right-angle through-hole), and thermal operating range (-55°C ~ 130°C).

The primary distinction between these parts is product status and regulatory compliance. The 207541-3 is classified as obsolete and carries no RoHS designation. The 207541-7 is an active product with ROHS3 compliance certification, indicating conformance to current environmental and material restriction directives.

An additional technical distinction exists in the post contact finish: 207541-3 uses Tin-Lead plating, while 207541-7 uses Tin plating. This represents a lead-free upgrade aligned with modern manufacturing standards. Both finishes maintain the specified 150.0µin (3.81µm) thickness and are compatible with standard solder assembly processes.

For new designs, production continuity, and service applications requiring this connector type, the 207541-7 is the appropriate selection. The component is currently in stock with higher inventory availability (1093 pieces) compared to the obsolete variant.
