• DPDT circuit configuration
• 5A current rating (AC/DC)
• 120V AC voltage rating
• 28V DC voltage rating
• On-On switch function
• 6,000 cycle electrical life

Mechanical Equivalence Criteria:

• Through-hole, right-angle mounting design
• Concave (Standard V) actuator type
• PC pin termination style
• Epoxy-sealed terminal construction
• Operating temperature range of -30°C to 85°C

Compliance Equivalence:

• ROHS3 compliance
• EAR99 ECCN classification
• 8536.50.9065 HTSUS code

The substitute part 1571987-2 differs only in actuator color (black versus red) and product status (active versus obsolete), with no impact on electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1571987-2 is the direct functional equivalent for the obsolete 1571987-3. Selection of the substitute part is based on the following engineering criteria:

Product Status Justification: The 1571987-3 carries obsolete status, indicating discontinued production and limited availability. The 1571987-2 maintains active production status, ensuring reliable supply chain access and long-term component availability for new designs and field service replacements.

Compliance Alignment: Both parts maintain identical ROHS3 compliance certification and EAR99 ECCN classification, satisfying regulatory requirements for equivalent substitution in applications subject to environmental and export control standards.

Functional Equivalence: Electrical and mechanical parameters are identical across all critical specifications: DPDT circuit, 5A/120V AC rating, 28V DC rating, through-hole right-angle mounting, and 6,000-cycle electrical life. These parameters determine functional compatibility in the application circuit.

Cosmetic Differentiation: The actuator color difference (red to black) is a cosmetic variation with no impact on electrical performance or mechanical function. This difference may be considered in applications where actuator color carries operational or identification significance.

Packaging Consideration: The substitute part is available in bulk packaging, which may affect procurement strategy and inventory management compared to the original part's unspecified packaging format.

Frequently Asked Questions (FAQ)

Q: Can the 1571987-2 be used as a direct replacement for the 1571987-3 in existing circuit designs?

A: Yes. The 1571987-2 is electrically and mechanically equivalent to the 1571987-3. Both parts share identical DPDT circuit configuration, 5A/120V AC and 28V DC ratings, through-hole right-angle mounting, and PC pin termination. No circuit modifications are required for substitution.

Q: What is the significance of the different actuator colors between these parts?

A: The actuator color difference (red on 1571987-3 versus black on 1571987-2) is cosmetic and does not affect electrical performance or mechanical function. Color selection may be relevant only in applications where actuator color serves an operational or identification purpose.

Q: Why is the 1571987-3 classified as obsolete?

A: Obsolete status indicates that TE Connectivity has discontinued production of this part number. The 1571987-2 represents the active production equivalent, ensuring ongoing availability and supply chain continuity.
