Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 63489-1 terminal is determined by strict equivalence across the following critical parameters:

• Series and Style: Both parts belong to the Mag-Mate 300 series, ensuring mechanical and electrical compatibility within the connector system
• Terminal Type and Configuration: Box IDC terminal type with tab termination must remain consistent
• Size Designation: Size 2 specification must be maintained for proper mating and contact integrity
• Wire Gauge Range: 23-27 AWG specification ensures correct current-carrying capacity and contact pressure
• Moisture Sensitivity Level: MSL 1 (Unlimited) classification indicates no moisture sensitivity constraints during storage or handling
• Regulatory Compliance: RoHS compliance status ensures environmental and regulatory alignment

The substitute part 63973-1 meets all these parameters and is classified as active product status, providing continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can 63973-1 be used as a direct replacement for 63489-1 in existing designs?

A: Yes. The 63973-1 terminal is electrically and mechanically equivalent to 63489-1 across all specified parameters, including wire gauge, terminal type, series designation, and size classification. No design modifications are required.

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

A: The 63489-1 is classified as obsolete, meaning the manufacturer no longer produces or supports this part number. The 63973-1 is classified as active, indicating current production and manufacturer support. For new designs and ongoing production, the active part number 63973-1 is the appropriate selection.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are RoHS compliant. The 63489-1 carries ROHS3 compliance designation, while 63973-1 carries RoHS compliance designation. Both meet current environmental and regulatory requirements. The MSL rating of 1 (Unlimited) is identical for both parts, indicating no moisture sensitivity constraints.

Q: Does the packaging format affect compatibility?

A: No. The packaging format difference (unspecified for 63489-1 versus Tape & Reel for 63973-1) does not affect electrical or mechanical compatibility. Tape & Reel packaging is the standard distribution format for terminal components and is compatible with automated assembly equipment.

Q: What wire gauge range does this terminal accommodate?

A: Both the 63489-1 and 63973-1 terminals are rated for 23-27 AWG wire gauges. This range must be strictly observed during application to ensure proper contact pressure and current-carrying capacity.

Q: Are these terminals suitable for high-moisture environments?

A: Yes. Both terminals carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity. These components can be stored and operated without moisture-related constraints.
