Frequently Asked Questions (FAQ)

Q: Why is the TE Connectivity 1551962-3 classified as obsolete?

A: The TE Connectivity 1551962-3 has reached end-of-life status within the manufacturer's product portfolio. Obsolete classification indicates discontinued production and limited availability of new inventory. The Mill-Max 1578-3-57-15-00-00-03-0 provides functional continuity for applications requiring single-position, surface mount gold-plated connectors.

Q: Are the TE Connectivity 1551962-3 and Mill-Max 1578-3-57-15-00-00-03-0 mechanically interchangeable?

A: Both components share identical mounting type (surface mount) and termination method (solder). Mechanical interchangeability is determined by PCB pad layout and footprint compatibility. The Mill-Max part features a circular pad layout dimension of 0.078" (1.98mm) diameter with 0.055" (1.40mm) height. PCB design review is required to confirm footprint alignment with existing layouts.

Q: What is the difference between a header spacer and a contact spring target?

A: The TE Connectivity 1551962-3 functions as a header spacer connector, providing structural positioning for single-position connections. The Mill-Max 1578-3-57-15-00-00-03-0 operates as a contact spring target, utilizing spring-loaded contact technology for reliable mating cycles. Both components achieve equivalent electrical and mechanical function within single-position, surface mount applications.

Q: Do both parts meet the same regulatory compliance standards?

A: Both components maintain ROHS3 compliance and MSL 1 (Unlimited) classification. The Mill-Max substitute provides enhanced regulatory status with REACH Unaffected designation, compared to the TE Connectivity original part's REACH Affected status. This represents an improvement in regulatory compliance profile.

Q: What is the operating temperature range for the substitute part?

A: The Mill-Max 1578-3-57-15-00-00-03-0 operates across the temperature range of -55°C to 125°C. This specification is provided for the substitute component; the original TE Connectivity part's operating temperature range was not specified in available documentation.

Q: Is the gold contact finish thickness specified for both parts?

A: The Mill-Max substitute specifies gold contact finish thickness of 10.0µin (0.25µm). The TE Connectivity original part does not provide contact finish thickness specification. The Mill-Max specification ensures consistent gold plating quality and corrosion resistance performance.

Q: What packaging format is available for the Mill-Max substitute?

A: The Mill-Max 1578-3-57-15-00-00-03-0 is supplied in Tape & Reel (TR) packaging format, suitable for automated surface mount assembly processes. This packaging format supports high-volume production environments and component handling efficiency.
