Molex 0452802002 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0452802002 is a Micro-Fit 3.0 BMI CPI rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This connector features 20 positions arranged in 2 rows with 0.118" (3.00mm) pitch and shrouded 4-wall construction. The part is currently classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0452802002 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating interface (Header, Male Pin)
• Position count and row configuration (20 positions, 2 rows)
• Pitch specifications (0.118" / 3.00mm mating pitch and row spacing)
• Mounting method (Through Hole)
• Shrouding design (Shrouded - 4 Wall)
• Termination capability (Press-Fit, Solder)
• Fastening mechanism (Push-Pull)
• Series compatibility (Micro-Fit 3.0 BMI CPI 45280)
• Insulation material and flammability rating (Polyamide/Nylon Glass Filled, UL94 V-0)

The substitute part Molex 0452802052 maintains full equivalence across all these parameters. Differences exist only in product status (Active vs. Obsolete), packaging format (Tray vs. standard), contact finish post composition (Tin vs. Tin-Lead), and regulatory compliance status (RoHS3 Compliant vs. non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0452802052 is the direct active equivalent for the obsolete Molex 0452802002. Both connectors are functionally identical across all electrical and mechanical parameters critical to board-to-board connectivity in the Micro-Fit 3.0 series.

Selection of the 0452802052 is supported by its Active product status, ensuring ongoing availability and manufacturer support. The part achieves ROHS3 compliance, meeting current regulatory requirements for new designs and procurement cycles. The change in contact finish post composition from Tin-Lead to Tin reflects modern manufacturing standards and does not affect mating interface performance, as the mating contact finish remains Gold at identical thickness specifications.

For applications requiring the original Tin-Lead post finish specification, the 0452802002 remains available in current inventory (920 pieces). However, for new designs and long-term supply chain continuity, the 0452802052 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Are the 0452802002 and 0452802052 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.118" / 3.00mm), row configuration (2 rows, 20 positions), mounting type (Through Hole), shrouding design (4-wall), and overall dimensions. They are direct mechanical substitutes.

Q: What is the difference in contact finish between these parts?

A: The primary difference is the post finish: the 0452802002 uses Tin-Lead, while the 0452802052 uses Tin. The mating contact finish is Gold at identical thickness (15.0µin / 0.38µm) for both parts. This post finish change does not affect mating interface performance or electrical characteristics.

Q: Why is the 0452802002 classified as obsolete?

A: The 0452802002 has been superseded by the 0452802052, which offers improved regulatory compliance (ROHS3) and modern manufacturing standards. Molex continues to support the Micro-Fit 3.0 series through the active 0452802052 variant.

Q: Can I use the 0452802052 in a design originally specified for the 0452802002?

A: Yes. The 0452802052 is a direct functional and mechanical equivalent. The change to Tin post finish and improved RoHS compliance make it suitable for all applications previously using the 0452802002.

Q: What is the difference in packaging between these parts?

A: The 0452802002 is supplied in standard packaging, while the 0452802052 is supplied in Tray packaging. This affects handling and storage but does not impact connector performance or compatibility.

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

A: Both connectors are specified for General Purpose, Medical, Military, and Telecommunications applications. The 0452802052's improved compliance status makes it the preferred choice for new medical and military designs.
