Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1571219-2 is the direct substitute for the obsolete 1571219-1. Selection of the 1571219-2 is based on the following engineering criteria:

Functional Equivalence: All electrical and mechanical parameters are identical between the main part and substitute. The 1571219-2 maintains the same SPST-NO circuit configuration, 0.05A @ 24VDC contact rating, momentary switch function, and physical form factor.

Product Status: The 1571219-1 is classified as obsolete, creating supply chain risk. The 1571219-2 carries active product status, ensuring ongoing availability and manufacturer support.

Compliance Enhancement: The 1571219-2 is ROHS3 compliant, whereas the 1571219-1 status is not applicable. This compliance upgrade aligns with current regulatory requirements for electronic components in many jurisdictions.

Design Compatibility: The 1571219-2 includes a board guide feature in addition to the sealed design present in the main part. This enhancement improves mechanical stability during assembly without affecting electrical performance or physical footprint.

Inventory Availability: Both parts are currently in stock. The 1571219-2 maintains sufficient inventory (740 pieces) to support production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1571219-2 be used as a direct replacement for the 1571219-1 in existing designs?

A: Yes. The 1571219-2 is electrically and mechanically equivalent to the 1571219-1 across all specified parameters. No design modifications are required for substitution. The component maintains identical contact ratings, actuator specifications, mounting type, and environmental performance.

Q: What is the difference between the 1571219-1 and 1571219-2?

A: The primary differences are product status and compliance. The 1571219-1 is obsolete, while the 1571219-2 is active. The 1571219-2 is ROHS3 compliant and includes a board guide feature. All electrical and mechanical specifications remain identical.

Q: Does the board guide feature on the 1571219-2 affect PCB layout or footprint?

A: No. The board guide is an internal mechanical feature that does not alter the external outline dimensions (12.00mm x 12.00mm) or the PC pin termination pattern. PCB layouts designed for the 1571219-1 are fully compatible with the 1571219-2.

Q: Are there packaging differences between these parts?

A: Yes. The 1571219-1 is supplied in bulk packaging, while the 1571219-2 is supplied in bag packaging. This difference does not affect component performance or compatibility. Packaging selection should be based on production workflow and inventory management requirements.

Q: What is the operating force specification, and does it differ between parts?

A: Both parts specify an operating force of 160gf (gram-force). This parameter defines the actuation pressure required to engage the switch and remains constant across both part numbers.

Q: Are these switches suitable for sealed or waterproof applications?

A: Yes. Both the 1571219-1 and 1571219-2 are rated IP67 (Dust Tight, Waterproof) with fully sealed construction. They are suitable for applications requiring protection against dust ingress and temporary water immersion.

Q: What is the mechanical life expectancy?

A: Both parts are rated for 1,000,000 mechanical cycles. This specification defines the expected operational lifespan under normal switching conditions.

Q: Do these switches require special handling or storage conditions?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage practices are sufficient.
