Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 532903-6 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 180
• Pitch: 0.100" (2.54mm)
• Number of Rows: 4
• Mounting Type: Through Hole, Right Angle
• Connector Style: High Density (HDC, HDI, HPC)
• Contact Finish: Gold with 30.0µin (0.76µm) thickness
• Operating Temperature Range: -65°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Termination Method: Solder
• Housing Color: Brown
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5532903-6 meets all mandatory matching parameters and is therefore classified as a direct equivalent. The primary distinction between the main part and its substitute relates to regulatory compliance status, which does not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 532903-6 and 5532903-6 are electrically and mechanically interchangeable for PCB-level backplane connector applications. Selection between these parts should be based on the following criteria:

532903-6 (Main Part): Select this part number when RoHS non-compliant components are acceptable within the design specification or when existing inventory and procurement channels are optimized for this variant. This part maintains Active product status with 950 pieces currently in stock.

5532903-6 (Substitute): Select this part number when ROHS3 compliance is a mandatory requirement for the end application or when regulatory frameworks require adherence to RoHS directives. This variant is ROHS3 compliant and maintains Active product status with 977 pieces currently in stock. All electrical and mechanical characteristics remain identical to the main part.

Both parts are suitable for operating environments spanning -65°C to 125°C and meet UL94 V-0 flammability standards. The choice between these variants does not impact circuit performance, signal integrity, or mechanical fit within the PCB assembly.

Frequently Asked Questions (FAQ)

Q: Are the 532903-6 and 5532903-6 connectors mechanically interchangeable?

A: Yes. Both connectors feature identical mechanical specifications including 180 positions, 0.100" (2.54mm) pitch, 4-row configuration, through-hole right-angle mounting, and brown housing. They are direct mechanical substitutes.

Q: What is the primary difference between these two part numbers?

A: The primary difference is regulatory compliance status. The 532903-6 is RoHS non-compliant, while the 5532903-6 is ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Can I use the 5532903-6 as a replacement for the 532903-6 in an existing design?

A: Yes. The 5532903-6 is a direct substitute with identical electrical and mechanical characteristics. The ROHS3 compliance of the substitute part does not create any incompatibility with designs originally specified for the 532903-6.

Q: Do these connectors require any special handling or storage considerations?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What is the contact finish specification for these connectors?

A: Both connectors feature gold-plated contacts with a thickness of 30.0µin (0.76µm), providing reliable electrical contact and corrosion resistance.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both connectors are rated for operating temperatures from -65°C to 125°C, making them suitable for industrial and telecommunications applications across extended temperature ranges.

Q: What termination method is used for these connectors?

A: Both connectors use solder termination for through-hole PCB mounting, requiring standard wave or reflow soldering processes.

Q: Is there a difference in availability between these two part numbers?

A: Current inventory shows 950 pieces of the 532903-6 and 977 pieces of the 5532903-6 in stock. Both parts maintain Active product status.
