Key Parameters

Substitute Part Grouping Explanation

The Keystone Electronics 577 qualifies as a direct substitute for the 572 based on matching electrical and mechanical parameters. Both connectors share identical specifications across all critical substitution criteria: 3.20mm ID, 9.00mm OD RCA mating diameter, female gender, mono signal configuration, 2-contact arrangement, through-hole mounting, kinked pin termination, unshielded design, tin-plated brass contacts, and ROHS3 compliance. The primary distinction is product status: the 572 is obsolete while the 577 maintains active production status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 577 is the appropriate selection for applications currently specified with the 572. Both connectors maintain identical electrical and mechanical compatibility across all functional parameters. The 577 offers the advantage of active product status, ensuring reliable procurement and supply chain continuity. Both parts satisfy ROHS3 compliance and MSL 1 requirements, making them suitable for standard PCB assembly processes without moisture sensitivity constraints. The body material difference (steel versus brass) does not affect electrical performance or mechanical fit for standard RCA phono jack applications.

Frequently Asked Questions (FAQ)

Q: Can the 577 be used as a direct replacement for the 572 in existing designs?

A: Yes. The 577 and 572 share identical specifications for connector type, mating diameter, contact configuration, mounting method, and termination style. No design modifications are required.

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

A: The 572 is classified as obsolete, indicating discontinued production. The 577 maintains active status, ensuring ongoing availability and supply chain support for new procurement and production runs.

Q: Are there packaging differences between these parts?

A: The 572 is supplied in standard packaging, while the 577 is available in bulk packaging. Both configurations contain identical connector components.

Q: Do both connectors meet current compliance standards?

A: Yes. Both the 572 and 577 are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, meeting standard PCB assembly and storage requirements.

Q: Is the body material change from steel to brass significant?

A: For standard RCA phono jack applications, the body material difference does not affect electrical performance, mechanical fit, or signal integrity. Both materials provide adequate structural support and contact reliability.
