Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1618458 is the direct equivalent for applications currently using the 1618261. Selection is based on:

• Identical mechanical and electrical interface specifications (contact size, termination method, series compatibility)
• Active product status ensuring ongoing availability and supply chain support
• Enhanced regulatory compliance (ROHS3 Compliant with REACH Affected status)
• Expanded wire gauge compatibility (0.25 ~ 1.0mm²) providing broader application flexibility
• Identical MSL and export classification parameters

The transition from 1618261 to 1618458 presents no functional or compatibility constraints for existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 1618458 be used as a direct replacement for the 1618261 in existing assemblies?

A: Yes. Both components share identical contact size (1.0mm), termination method (crimp), series designation (ST), and signal pin configuration. The 1618458 is mechanically and electrically interchangeable.

Q: What is the significance of the expanded wire gauge range in the 1618458?

A: The 1618458 supports 0.25 ~ 1.0mm² wire gauges compared to the original 0.5 ~ 1.0mm² range. This expanded range provides compatibility with a broader selection of wire sizes without affecting applications using the original 0.5 ~ 1.0mm² specification.

Q: Why is the 1618261 listed as obsolete?

A: Product obsolescence reflects Phoenix Contact's lifecycle management. The 1618458 represents the current active equivalent within the ST series pin contact portfolio.

Q: Are there packaging differences between these components?

A: The 1618261 packaging specification is not provided. The 1618458 is supplied in bulk packaging, which is standard for individual contact pins in this category.

Q: Do compliance certifications differ between the two parts?

A: The 1618261 carries RoHS Compliant status. The 1618458 carries ROHS3 Compliant status with REACH Affected designation, reflecting current regulatory requirements. Both maintain identical MSL ratings and export classifications.
