Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 3-1571986-0 is based on electrical and mechanical parameter equivalence within the ALCOSWITCH Series A product line. The primary substitute, part number 3-1571986-4, maintains identical electrical specifications including SPDT circuit configuration, 5A current rating, 120V AC and 28V DC voltage ratings, and On-On switch function. Both components share the same actuator type (concave standard V), color (black), operating temperature range (-30°C to 85°C), and electrical life rating (6,000 cycles).

The key differentiating parameters between the main part and its substitute are:

• Termination style (Quick Connect 0.062" versus Solder Lug)
• Panel cutout dimensions (15.75mm x 12.70mm versus 15.24mm x 12.70mm)
• Product status (Obsolete versus Active)
• Packaging configuration (unspecified versus Bulk)
• RoHS compliance status (Not applicable versus ROHS3 Compliant)
• Moisture sensitivity level (Not Applicable versus 1 - Unlimited)

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 3-1571986-4 serves as the manufacturer-recommended substitute for the obsolete 3-1571986-0. Both components are electrically and functionally equivalent across all critical parameters: SPDT circuit configuration, 5A current capacity, 120V AC and 28V DC voltage ratings, concave black actuator, snap-in panel mounting, and 6,000-cycle electrical life.

Selection between these parts depends on application-specific requirements:

Choose 3-1571986-0 (Original Part) when legacy system compatibility requires Quick Connect 0.062" (1.5mm) termination and the larger panel cutout dimension of 15.75mm x 12.70mm. This part remains available in inventory (636 pieces) despite obsolete status.

Choose 3-1571986-4 (Substitute Part) for new designs, system upgrades, or replacements where solder lug termination is acceptable and the smaller panel cutout dimension of 15.24mm x 12.70mm accommodates the installation. This active product offers ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), providing enhanced environmental and regulatory alignment for modern applications. Inventory availability is higher (1,195 pieces) in bulk packaging.

Both parts share identical electrical performance characteristics and operating parameters, ensuring functional equivalence in SPDT switching applications within the specified voltage and current ranges.

Frequently Asked Questions (FAQ)

Q: Are the 3-1571986-0 and 3-1571986-4 electrically interchangeable?

A: Yes. Both components are electrically identical with SPDT configuration, 5A current rating, 120V AC and 28V DC voltage ratings, and 6,000-cycle electrical life. Electrical performance and switching characteristics are equivalent.

Q: What is the primary difference between these two parts?

A: The main differences are termination style (Quick Connect 0.062" versus Solder Lug) and panel cutout dimensions (15.75mm x 12.70mm versus 15.24mm x 12.70mm). The substitute part is also active and ROHS3 compliant, whereas the original is obsolete.

Q: Can I use 3-1571986-4 as a direct replacement for 3-1571986-0 in an existing system?

A: Mechanical compatibility depends on your panel cutout dimensions and termination requirements. If your panel is designed for the 15.75mm x 12.70mm cutout and Quick Connect termination, the substitute's 15.24mm x 12.70mm cutout and solder lug termination require panel modification or rewiring. Verify panel specifications before substitution.

Q: Why is the original part obsolete?

A: The 3-1571986-0 is classified as obsolete by TE Connectivity. The 3-1571986-4 represents the current active product line continuation with improved compliance and environmental ratings.

Q: Does the substitute part meet RoHS requirements?

A: Yes. The 3-1571986-4 is ROHS3 compliant. The original 3-1571986-0 has RoHS status listed as "Not applicable" due to its obsolete classification.

Q: Are there any performance differences in switching speed or response time?

A: No performance differences are specified in the provided parameters. Both components maintain identical electrical life (6,000 cycles) and operating temperature range (-30°C to 85°C).

Q: What termination style should I choose for my application?

A: Quick Connect 0.062" (1.5mm) termination (3-1571986-0) is suitable for quick-disconnect applications. Solder lug termination (3-1571986-4) is appropriate for permanent soldered connections. Select based on your circuit board or wiring harness design requirements.

Q: Is the panel cutout dimension difference significant?

A: Yes. The 0.51mm difference in the horizontal dimension (15.75mm versus 15.24mm) may affect fit in existing panel cutouts. Verify your panel specifications before selecting the substitute part.
