Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RP19-PC-121 is determined by strict alignment of the following critical parameters:

• Wire gauge compatibility: 24-30 AWG range
• Contact termination method: Crimp
• Contact material: Phosphor bronze
• Series designation: RP13
• Base product number: RP19
• Contact type: Pin
• Insulation support feature presence

The RP19-PC-122 qualifies as a direct substitute based on matching all mandatory electrical and mechanical parameters. The primary distinction between the main part and its substitute is the contact finish specification: gold versus silver. Both finishes are applied to the same phosphor bronze substrate and maintain equivalent electrical and mechanical performance within the defined wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The RP19-PC-122 is the manufacturer-recommended substitute for the obsolete RP19-PC-121. Both parts maintain identical electrical and mechanical specifications across all critical parameters including wire gauge range, termination method, contact material, and series designation.

The RP19-PC-122 offers the advantage of active product status, ensuring continued availability and manufacturing support. It carries ROHS3 compliance certification, representing current regulatory alignment. The silver contact finish provides equivalent performance to the gold finish of the original part while maintaining full compatibility with the RP13 series connector system.

Selection between these parts should be based on application-specific requirements regarding contact finish material properties and regulatory compliance timelines. Both parts are suitable for direct substitution in 24-30 AWG crimp pin contact applications within circular connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can RP19-PC-122 be used as a direct replacement for RP19-PC-121?

A: Yes. Both parts share identical wire gauge range (24-30 AWG), contact termination method (crimp), contact material (phosphor bronze), series designation (RP13), and insulation support features. The contact finish differs (silver versus gold) but does not affect mechanical or electrical compatibility within the specified parameters.

Q: What is the significance of the product status difference?

A: The RP19-PC-121 is classified as obsolete, indicating discontinued manufacturing. The RP19-PC-122 maintains active status, ensuring ongoing availability, manufacturing support, and compliance with current regulatory standards. For new designs or long-term supply chain planning, the active part is the appropriate selection.

Q: Are there compliance differences between the two parts?

A: The RP19-PC-121 carries RoHS Compliant certification. The RP19-PC-122 carries ROHS3 Compliant certification, representing alignment with the most current regulatory requirements. Both parts meet their respective compliance frameworks.

Q: Does the contact finish change affect electrical performance?

A: Both gold and silver finishes are applied to the same phosphor bronze substrate. Within the specified 24-30 AWG wire gauge range and crimp termination application, both finishes deliver equivalent electrical performance.

Q: What packaging considerations apply to these parts?

A: The RP19-PC-121 is supplied in standard packaging. The RP19-PC-122 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
