Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1-1571986-2 is determined by the following critical parameters:

Circuit Configuration: Both the main part and substitute maintain SPDT topology with On-On switch function, ensuring identical logical switching behavior.

Actuator Design: Both components feature a concave standard V-type actuator in black, providing consistent user interface and mechanical engagement characteristics.

Termination Style: Both parts utilize PC pin termination, enabling direct connection compatibility in existing circuit board layouts.

Operating Temperature Range: Both components operate across -30°C to 85°C, maintaining thermal performance consistency.

Electrical Life: Both parts are rated for 6,000 cycles, providing equivalent mechanical durability.

Series Designation: Both components belong to the TE Connectivity ALCOSWITCH Series A family.

Epoxy Sealed Terminals: Both parts feature epoxy sealed terminals, providing equivalent environmental protection.

The substitute part 1-1571986-4 differs in mounting configuration (Through Hole versus Panel Mount Flange), current rating (0.4VA versus 5A), and voltage specifications (20V AC/DC versus 120V AC/28V DC). These differences require application-specific evaluation based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1-1571986-2 is classified as obsolete. The substitute part 1-1571986-4 is an active product within the same Series A family, offering continued availability and supply chain support.

Compliance Considerations: The substitute part 1-1571986-4 carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs and applications subject to environmental directives. The original part carries vendor-undefined REACH status and non-applicable RoHS classification.

Electrical Rating Differences: The substitute part operates at reduced current (0.4VA) and voltage (20V AC/DC) specifications compared to the main part (5A at 120V AC/28V DC). Component selection must verify that application circuit requirements do not exceed the substitute part's electrical ratings.

Mechanical Configuration: The substitute part utilizes Through Hole mounting, whereas the original employs Panel Mount Flange configuration. PCB layout and mechanical assembly requirements must accommodate this mounting type difference.

Functional Equivalence: Both components maintain identical SPDT On-On switching topology, actuator design, termination style, and thermal operating range, ensuring functional compatibility within electrical specification constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1-1571986-4 directly replace the 1-1571986-2 in existing applications?

A: Direct replacement requires verification of three critical factors: (1) circuit voltage and current requirements must not exceed 20V AC/DC and 0.4VA ratings; (2) PCB layout must accommodate Through Hole mounting instead of Panel Mount Flange configuration; (3) mechanical panel cutout dimensions are not applicable for the substitute part due to its through-hole design.

Q: What are the key electrical differences between these parts?

A: The main part is rated for 5A at 120V AC and 28V DC. The substitute part is rated for 0.4VA at 20V AC/DC. Applications requiring higher current or voltage must retain the original part specification or identify alternative components with appropriate electrical ratings.

Q: Are both parts functionally equivalent in terms of switching behavior?

A: Yes. Both components feature SPDT configuration with On-On switching function, identical actuator design (concave standard V-type, black), PC pin termination, and 6,000-cycle electrical life. Functional switching behavior is equivalent within their respective electrical rating limits.

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

A: The original part (1-1571986-2) is obsolete and no longer manufactured. The substitute part (1-1571986-4) is active and maintains current production and supply availability. New designs should specify the active part to ensure long-term component availability.

Q: How do the mounting types affect component selection?

A: The original part uses Panel Mount Flange configuration with a rectangular 17.96mm x 10.62mm panel cutout. The substitute uses Through Hole mounting without panel cutout requirements. PCB design and mechanical assembly must be evaluated to determine compatibility with the substitute mounting type.

Q: What compliance advantages does the substitute part offer?

A: The substitute part (1-1571986-4) is ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements. The original part carries vendor-undefined REACH status and non-applicable RoHS classification, which may present compliance challenges for new applications subject to environmental directives.

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across -30°C to 85°C, providing equivalent thermal performance and environmental operating capability.
