Molex 0022303073 Equivalent & Substitute Parts

Part Overview

The Molex 0022303073 is a vertical rectangular connector header designed for through-hole mounting applications. This 7-position, 2.54mm pitch connector is classified as active and widely used in board-to-board and cable interconnect applications across automotive, medical, telecommunications, and general purpose industries. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional equivalents.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022303073 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header, Breakaway with Male Pin contacts
• Position Count & Pitch: 7 positions at 0.100" (2.54mm) mating pitch
• Mounting Method: Through-hole solder termination
• Electrical & Mechanical Compatibility: Single-row, board-to-board or cable style, unshrouded design
• Compliance & Environmental: UL94 V-0 flammability rating, ROHS3 compliance, REACH unaffected status

The identified substitute parts (PBC07SFAN and PEC07SFAN) maintain these core parameters. Variations in contact length, insulation material composition, contact finish specifications, and operating temperature ranges are secondary parameters that do not prevent functional substitution when design margins permit.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full compliance with ROHS3 and REACH regulatory requirements. The Molex 0022303073 and both Sullins alternatives (PBC07SFAN and PEC07SFAN) are suitable for applications requiring UL94 V-0 flammability certification.

Molex 0022303073 remains the primary specification when exact dimensional and contact geometry matching is required, particularly for applications with tight mechanical tolerances or specific contact length requirements.

Sullins PBC07SFAN provides an alternative with gold-plated mating contacts, which may offer enhanced corrosion resistance in certain environmental conditions. This part is suitable when contact finish upgrade is beneficial.

Sullins PEC07SFAN provides a direct functional equivalent with tin-plated mating contacts matching the original specification. This part offers the closest electrical and material profile alignment with the Molex original.

Selection between substitute parts should be based on design-specific requirements regarding contact finish, insulation material composition, and mechanical envelope constraints.

Frequently Asked Questions (FAQ)

Q: Can PBC07SFAN and PEC07SFAN be used interchangeably with the Molex 0022303073?

A: Both Sullins parts maintain the critical parameters for functional substitution: 7-position, 2.54mm pitch, through-hole male pin header configuration, and UL94 V-0 compliance. Mechanical envelope differences (contact length and insulation height) must be evaluated against specific PCB layout and mating connector specifications.

Q: What is the primary difference between PBC07SFAN and PEC07SFAN?

A: The primary difference is the mating contact finish. PBC07SFAN features gold plating (10.0µin thickness) on mating contacts, while PEC07SFAN uses tin plating (100.0µin thickness). Both use phosphor bronze contact material and PBT insulation. Contact finish selection depends on application requirements for corrosion resistance and contact wear characteristics.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: Yes. The Molex 0022303073 has a mating contact length of 0.405" (10.29mm) and insulation height of 0.090" (2.29mm), while both Sullins alternatives have shorter mating contact lengths of 0.318" (8.08mm) and increased insulation height of 0.100" (2.54mm). These differences may affect mating depth and PCB stack-up. Verify compatibility with mating connector specifications and PCB design constraints.

Q: Do all three parts meet the same regulatory and compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability certification. They are suitable for applications requiring these compliance levels.

Q: What operating temperature range should be assumed for the Molex 0022303073?

A: The Molex 0022303073 does not specify an operating temperature range in the provided data. The Sullins alternatives specify -65°C ~ 125°C. For applications requiring confirmed temperature ratings, consult the Molex datasheet or contact the manufacturer directly.
