Parameter Comparison

Engineering Selection Recommendations

The 5558872-1 serves as a direct functional equivalent to the obsolete 558872-1 across all electrical and mechanical parameters. Both connectors are manufactured by TE Connectivity AMP Connectors and maintain identical specifications for connector type, contact configuration, mounting method, termination approach, and operating characteristics.

Product Status Consideration: The 558872-1 is classified as obsolete, while the 5558872-1 maintains active product status. This distinction is significant for long-term supply chain planning and component availability.

Regulatory Compliance Advantage: The 5558872-1 provides improved regulatory positioning through RoHS compliance and REACH unaffected status, compared to the non-compliant and REACH-affected status of the 558872-1. This compliance improvement supports current manufacturing standards and regulatory requirements without requiring design modifications.

Packaging Difference: The 5558872-1 is supplied in tray packaging, whereas the main part packaging specification is not provided. This packaging difference does not affect electrical or mechanical compatibility and relates only to handling and storage logistics.

Frequently Asked Questions (FAQ)

Q: Can the 5558872-1 be used as a direct replacement for the 558872-1 in existing designs?

A: Yes. The 5558872-1 maintains identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, mounting method, termination approach, shielding, ratings, contact materials, housing material, and operating temperature range. Pin-for-pin and footprint compatibility is assured.

Q: What is the significance of the product status difference between the two parts?

A: The 558872-1 is classified as obsolete, indicating it is no longer in active production. The 5558872-1 maintains active product status, ensuring ongoing availability, supply chain support, and manufacturing continuity. For new designs or ongoing production requirements, the active substitute is the appropriate selection.

Q: How do the RoHS and REACH compliance differences affect component selection?

A: The 5558872-1 is RoHS compliant and REACH unaffected, while the 558872-1 is RoHS non-compliant and REACH affected. If your application or manufacturing location requires RoHS compliance or REACH compliance, the 5558872-1 is the appropriate selection. The compliance improvement does not alter electrical or mechanical performance.

Q: Are there any differences in contact specifications between these connectors?

A: No. Both connectors use phosphor bronze contacts with identical gold plating specifications (50.0µin / 1.27µm thickness). Contact material, finish, and electrical performance are identical.

Q: Does the tray packaging of the 5558872-1 affect its functionality compared to the 558872-1?

A: No. Packaging format affects only handling, storage, and logistics. The tray packaging of the 5558872-1 does not alter electrical performance, mechanical compatibility, or functional characteristics. The connector itself is identical.

Q: What is the operating temperature range for both connectors?

A: Both the 558872-1 and 5558872-1 operate across the identical temperature range of -40°C to 85°C, ensuring equivalent thermal performance in all specified applications.

Q: Are both connectors suitable for Cat3 rated applications?

A: Yes. Both connectors carry Cat3 ratings and are suitable for telecommunications and data communication applications requiring this category specification.

Q: What mounting and termination methods are used for these connectors?

A: Both connectors use through-hole mounting with solder termination. They are designed for vertical orientation and include board lock functionality for secure PCB mounting.
