Substitute Part Grouping Explanation

Substitution of the obsolete Molex 0452801403 is based on strict electrical and mechanical compatibility within the Micro-Fit 3.0 BMI CPI 45280 series. The substitute part must maintain identical specifications across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (14 positions)
• Row configuration (2 rows)
• Mating pitch (0.118" / 3.00mm)
• Row spacing (0.118" / 3.00mm)
• Mounting method (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Contact geometry (Square)
• Insulation material (Polyamide, Nylon, Glass Filled)
• Insulation height (0.457" / 11.60mm)
• Contact post length (0.193" / 4.90mm)
• Mating contact finish (Gold)
• Contact material (Copper Alloy)
• Flammability rating (UL94 V-0)

The Molex 0452801453 satisfies all these requirements and serves as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0452801453 is the appropriate substitute for the obsolete 0452801403. Both connectors maintain identical mechanical and electrical interface specifications within the Micro-Fit 3.0 BMI CPI 45280 series, ensuring direct functional compatibility in board-to-board and cable applications.

The 0452801453 offers the following advantages:

• Active product status with current manufacturing support and availability
• ROHS3 compliance, meeting modern regulatory requirements for new designs and production
• Identical connector geometry, pitch, and mating interface specifications
• Equivalent flammability rating (UL94 V-0) for safety-critical applications
• Suitable for general purpose, medical, military, and telecommunications applications

The differences in post contact finish (Tin versus Tin-Lead) and post finish thickness do not affect the mating interface or electrical performance of the connector. These variations relate to soldering characteristics and are compatible with standard through-hole assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 0452801453 directly replace the 0452801403 in existing designs?

A: Yes. The 0452801453 maintains identical mating interface specifications, including pitch (0.118" / 3.00mm), position count (14), row configuration (2 rows), shrouding (4-wall), and fastening mechanism (push-pull). No PCB redesign or connector housing modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 0452801403 is obsolete and no longer manufactured. The 0452801453 is an active product with current manufacturing support, ensuring long-term availability for production and maintenance applications.

Q: How do the RoHS compliance differences affect substitution?

A: The 0452801403 is RoHS non-compliant, while the 0452801453 is ROHS3 compliant. For new designs and applications subject to RoHS regulations, the 0452801453 is the required choice. For legacy systems, both parts are functionally equivalent.

Q: Are there differences in contact finish that affect performance?

A: The main part uses Tin-Lead post finish (100.0µin / 2.54µm), while the substitute uses Tin post finish (10.0µin / 0.25µm). Both finishes are compatible with standard through-hole soldering processes. The mating contact finish (Gold, 30.0µin / 0.76µm) is identical on both parts, ensuring equivalent electrical performance at the mating interface.

Q: What packaging is available for the 0452801453?

A: The 0452801453 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

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

A: Yes. Both the 0452801403 and 0452801453 are rated for general purpose, medical, military, and telecommunications applications and meet UL94 V-0 flammability requirements.
