Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3-1571986-1 with the 3-1571986-4 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH Series A product line. Both parts maintain identical electrical specifications: SPDT circuit configuration, 5A current rating at 120V AC and 28V DC, On-On switch function, and 6,000-cycle electrical life. Both employ concave black actuators, epoxy sealed terminals, and operate across the same temperature range of -30°C to 85°C.

The primary distinction between these parts lies in termination style and product status. The 3-1571986-1 uses Quick Connect 0.062" (1.5mm) termination and is obsolete, while the 3-1571986-4 features Solder Lug termination and maintains active product status. Panel cutout dimensions differ marginally (15.75mm x 12.70mm versus 15.24mm x 12.70mm), and the 3-1571986-4 is RoHS3 compliant with MSL 1 rating, whereas the 3-1571986-1 is not RoHS applicable.

Substitution is valid when termination style compatibility and panel cutout accommodation are confirmed in the target application.

Parameter Comparison

Engineering Selection Recommendations

The 3-1571986-4 is the designated active equivalent for the obsolete 3-1571986-1. Selection of the substitute part is appropriate for new designs and production continuity where the following conditions are met:

Termination Compatibility: The 3-1571986-4 employs Solder Lug termination, whereas the original part uses Quick Connect 0.062" (1.5mm) termination. Circuit board or wiring harness design must accommodate solder lug connection methodology.

Panel Cutout Accommodation: The 3-1571986-4 panel cutout dimension is 15.24mm x 12.70mm compared to the original 15.75mm x 12.70mm. Panel mounting holes and cutouts must be verified for dimensional compatibility. The 0.51mm reduction in width may require panel modification or confirmation that existing cutouts provide adequate clearance.

Regulatory Compliance: The 3-1571986-4 is RoHS3 compliant with MSL 1 rating, providing enhanced environmental and moisture handling characteristics suitable for modern manufacturing and storage environments. The original part carries no RoHS applicability designation.

Electrical and Functional Equivalence: Both parts maintain identical electrical performance across all specified parameters, including current rating, voltage rating, circuit configuration, operating temperature range, and electrical life cycle rating.

Frequently Asked Questions (FAQ)

Q: Can the 3-1571986-4 directly replace the 3-1571986-1 in existing applications?

A: Electrical and functional replacement is direct. However, termination style and panel cutout dimensions must be verified for mechanical compatibility. The 3-1571986-4 uses Solder Lug termination instead of Quick Connect, and panel cutout width is 0.51mm narrower. Confirm that circuit board or panel design accommodates these differences before implementation.

Q: What is the significance of the termination style difference?

A: The 3-1571986-1 features Quick Connect 0.062" (1.5mm) termination, which uses push-on connectors. The 3-1571986-4 uses Solder Lug termination, requiring direct soldering to circuit board pads or wire connections. This affects assembly methodology and requires compatible connection infrastructure.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated for 5A at 120V AC and 28V DC, feature SPDT On-On configuration, operate across -30°C to 85°C, and provide 6,000 electrical life cycles. Electrical performance is equivalent.

Q: What does RoHS3 compliance mean for the 3-1571986-4?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting use of specified hazardous materials. This is relevant for applications subject to environmental regulations and is standard for modern component procurement.

Q: Why is the panel cutout dimension different?

A: The 3-1571986-4 has a panel cutout width of 15.24mm compared to the original 15.75mm. This 0.51mm difference may require panel modification or confirmation that existing cutouts provide adequate clearance. Measure panel openings before substitution.

Q: Is the 3-1571986-4 available in higher quantities than the original part?

A: Yes. The 3-1571986-4 is an active product with 1,195 pieces in stock, compared to the obsolete 3-1571986-1 with 762 pieces. Active status ensures ongoing availability for production requirements.

Q: What is the MSL 1 rating on the 3-1571986-4?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. This provides flexibility in storage and handling compared to higher MSL ratings that require controlled humidity environments.
