Key Parameters

Substitute Part Grouping Explanation

The Molex 0452801052 qualifies as a direct substitute for the 0452801002 based on the following critical parameters that determine functional and mechanical compatibility:

Matching Parameters:

• Identical series designation (Micro-Fit 3.0 BMI CPI 45280)
• Identical connector type (Header) and contact type (Male Pin)
• Identical position count (10 positions in 2 rows)
• Identical pitch specifications (0.118" / 3.00mm mating pitch and row spacing)
• Identical mounting method (Through Hole)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical termination options (Press-Fit, Solder)
• Identical fastening type (Push-Pull)
• Identical insulation material and physical dimensions
• Identical contact material (Copper Alloy)
• Identical mating contact finish (Gold)
• Identical flammability rating (UL94 V-0)

Distinguishing Differences:

• Product status: 0452801052 is Active (vs. Obsolete for 0452801002)
• Packaging: 0452801052 supplied in Tray (vs. unspecified for 0452801002)
• Contact finish - Post: 0452801052 uses Tin (vs. Tin-Lead for 0452801002)
• Contact finish thickness - Post: 0452801052 has 10.0µin (0.25µm) vs. 100.0µin (2.54µm) for 0452801002
• RoHS compliance: 0452801052 is ROHS3 Compliant (vs. RoHS non-compliant for 0452801002)

Parameter Comparison

Engineering Selection Recommendations

The Molex 0452801052 is the direct active equivalent for the obsolete 0452801002. Selection of the 0452801052 is appropriate for new designs and ongoing production support due to its active product status and ROHS3 compliance. The primary distinction is the post contact finish specification: the 0452801052 uses pure Tin plating versus the Tin-Lead plating of the original part. Both finishes are compatible with standard solder processes and provide equivalent electrical performance in the specified applications.

For applications requiring RoHS compliance, the 0452801052 is the mandated selection. For legacy systems currently using the 0452801002, the 0452801052 provides functional and mechanical interchangeability with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 0452801002 and 0452801052 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.118" / 3.00mm), position count (10 in 2 rows), mounting type (through-hole), shrouding configuration (4-wall), and overall dimensions. They are designed for the same mating interfaces and PCB footprints.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The 0452801002 uses Tin-Lead post plating while the 0452801052 uses pure Tin. Both finishes are compatible with standard solder reflow and wave soldering processes. The Tin finish in the 0452801052 reflects compliance with RoHS3 regulations that restrict lead content in electronic components.

Q: Can the 0452801052 be used as a direct replacement in existing assemblies?

A: Yes. The 0452801052 is functionally and mechanically equivalent to the 0452801002. No design modifications or PCB layout changes are required for substitution.

Q: Why is the 0452801002 listed as obsolete?

A: The 0452801002 is obsolete due to its RoHS non-compliant status. The 0452801052 represents the current active production equivalent that meets modern regulatory requirements.

Q: What packaging is supplied for the 0452801052?

A: The 0452801052 is supplied in Tray packaging, suitable for automated assembly processes and bulk procurement.

Q: Are both parts suitable for medical and military applications?

A: Yes. Both the 0452801002 and 0452801052 are specified for General Purpose, Medical, Military, and Telecommunications applications and carry the UL94 V-0 flammability rating.
