Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0873401822 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (18)
• Pitch specification (0.079" / 2.00mm)
• Row configuration (2 rows with 0.079" spacing)
• Mounting method (Surface Mount)
• Fastening mechanism (Push-Pull)
• Electrical ratings (1A current, 125VAC voltage)
• Operating temperature range (-55°C ~ 105°C)
• Series compatibility (Milli-Grid 87340)

The substitute part must maintain identical mechanical and electrical characteristics to ensure direct compatibility in existing designs without circuit modification or mechanical rework.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0873401824 serves as the direct substitute for the obsolete 0873401822. Both parts maintain identical mechanical and electrical specifications across all critical parameters, ensuring functional interchangeability in existing circuit designs.

The primary distinction between the parts is product status and regulatory compliance. The 0873401822 is obsolete and RoHS non-compliant, while the 0873401824 is an active product with ROHS3 compliance. The contact finish on the post differs (Tin-Lead versus Tin), reflecting the RoHS transition in manufacturing standards.

For new designs or component replenishment, the 0873401824 is the appropriate selection due to its active status and regulatory compliance. For legacy system maintenance where the original part specification must be preserved, the 0873401824 provides equivalent performance with improved compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the 0873401824 be used as a direct replacement for the 0873401822 in existing assemblies?

A: Yes. Both parts are mechanically and electrically identical across all functional parameters. The 0873401824 maintains the same 18-position configuration, 0.079" pitch, surface mount design, and electrical ratings (1A, 125VAC). No circuit modification or mechanical rework is required.

Q: What is the difference between the contact finishes on these parts?

A: The 0873401822 uses Tin-Lead post finish, while the 0873401824 uses Tin post finish. This difference reflects RoHS compliance requirements. Both maintain identical gold mating contact finish at 15.0µin thickness. The post finish change does not affect electrical performance or mating compatibility.

Q: Why is the 0873401822 listed as obsolete?

A: The 0873401822 has been superseded by the 0873401824 as part of Molex's product line transition to RoHS-compliant components. The 0873401824 provides equivalent functionality with improved regulatory compliance.

Q: Are there packaging differences between these parts?

A: The 0873401822 packaging is not specified in available documentation. The 0873401824 is supplied in Tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the 0873401822 and 0873401824 are rated for -55°C to 105°C operating temperature, ensuring equivalent thermal performance in all specified applications.
