Substitute Part Grouping Explanation

Substitution of the obsolete 5-1571986-9 is based on electrical and mechanical compatibility within the TE Connectivity ALCOSWITCH Series A product line. The substitute part 5-1571986-6 maintains functional equivalence through identical electrical specifications: SPDT circuit, Mom-Off-Mom switch function, 5A current rating at 120V AC and 28V DC, solder lug termination, and epoxy sealed terminals. Both parts share the same base product number (1571986), series designation (A), and operating temperature range (-30°C to 85°C).

The primary differences between the main part and substitute are:

• Actuator Type: Main part uses concave (standard V) actuator; substitute uses paddle actuator
• Panel Cutout Dimensions: Main part requires 27.81mm x 16.46mm rectangular cutout; substitute requires 17.96mm x 10.62mm rectangular cutout
• Product Status: Main part is obsolete; substitute is active
• Packaging: Main part uses standard packaging; substitute uses bulk packaging
• RoHS Compliance: Main part is not applicable; substitute is ROHS3 compliant

These differences establish the substitution relationship: the 5-1571986-6 provides electrical and functional equivalence with updated compliance status and active manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The 5-1571986-6 is the active equivalent substitute for the obsolete 5-1571986-9. Both components deliver identical electrical performance: SPDT circuit topology, 5A current capacity at 120V AC and 28V DC, Mom-Off-Mom switching function, and 6,000-cycle electrical life. Solder lug termination and epoxy sealed terminals are common to both parts, ensuring equivalent circuit integration.

The substitute part 5-1571986-6 provides superior compliance status with ROHS3 certification, addressing modern regulatory requirements. The active product status ensures continued manufacturing support, spare parts availability, and technical documentation access.

Panel cutout dimensions differ between the two parts. The substitute requires a smaller rectangular opening (17.96mm x 10.62mm versus 27.81mm x 16.46mm), necessitating mechanical redesign of panel mounting fixtures. The actuator type change from concave to paddle affects user interface ergonomics and may require operational procedure updates.

For new designs and production applications, the 5-1571986-6 is the specified selection. For field service and legacy system maintenance where the original concave actuator geometry is required, mechanical adaptation or custom panel modifications may be necessary to accommodate the substitute part's smaller cutout dimensions.

Frequently Asked Questions (FAQ)

Q: Are the electrical specifications identical between 5-1571986-9 and 5-1571986-6?

A: Yes. Both parts are rated for 5A at 120V AC and 28V DC with SPDT circuit configuration and Mom-Off-Mom switching function. Electrical life is 6,000 cycles for both components. Solder lug termination and epoxy sealed terminals are identical.

Q: What is the primary reason for substitution?

A: The 5-1571986-9 is classified as obsolete. The 5-1571986-6 is an active product with ongoing manufacturing support, ensuring component availability and compliance with current regulatory standards including ROHS3.

Q: Can the 5-1571986-6 be used as a direct replacement in existing equipment?

A: Electrical and functional compatibility is confirmed. However, the panel cutout dimensions differ: the substitute requires 17.96mm x 10.62mm versus the original 27.81mm x 16.46mm. Panel mounting fixtures must be mechanically adapted or redesigned. The actuator type change from concave to paddle may affect user interface characteristics.

Q: What are the compliance differences?

A: The 5-1571986-9 has not applicable RoHS status. The 5-1571986-6 is ROHS3 compliant. Both parts are REACH affected and classified as EAR99 for export control purposes.

Q: Is the actuator type change functionally significant?

A: Both actuator types (concave standard V and paddle) support the same Mom-Off-Mom switching function and operate within identical electrical parameters. The change affects physical ergonomics and panel aesthetics but not electrical performance or circuit behavior.

Q: What packaging options are available?

A: The 5-1571986-9 uses standard packaging. The 5-1571986-6 is supplied in bulk packaging, suitable for high-volume production environments.
