Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-1571926-5 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-Off-On
• Current rating must support minimum 6A at 125V AC
• Voltage ratings must meet or exceed 125V AC and 28V DC specifications
• Electrical life must be rated for 60,000 cycles or greater

Mechanical Equivalence Requirements:

• Mounting type must be panel mount
• Actuator type must be standard round
• Termination style must be solder lug
• Bushing thread must be 15/32-32
• Panel cutout dimensions must be compatible or unspecified

Environmental and Compliance Requirements:

• Operating temperature range must encompass or exceed -20°C to 80°C
• Epoxy sealed terminals required for environmental protection
• ECCN classification must be EAR99

The Electroswitch A221T11TXZQ meets all substitution criteria and is classified as an active product, providing a viable alternative for applications requiring DPDT toggle switch functionality with identical electrical ratings and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The Electroswitch A221T11TXZQ is a direct functional substitute for the obsolete TE Connectivity 2-1571926-5. Selection of this substitute is supported by the following engineering factors:

Electrical Performance: The substitute maintains identical DPDT circuit configuration, On-Off-On switching function, and meets or exceeds all voltage and current specifications. The DC current rating of 6A on the substitute exceeds the original 4A specification, providing additional operational margin.

Mechanical Interface: Panel mount configuration, standard round actuator geometry, solder lug termination, and 15/32-32 bushing thread are identical between the original and substitute parts, ensuring direct mechanical compatibility in existing panel cutouts and circuit board layouts.

Environmental Performance: The substitute operates across a wider temperature range (-30°C to 90°C) compared to the original (-20°C to 80°C), providing enhanced thermal performance for extended operating environments. Both parts feature epoxy sealed terminals for environmental protection. The substitute includes splash proof ingress protection, exceeding the original specification.

Product Availability and Compliance: The substitute is classified as an active product with current manufacturing status, ensuring long-term availability and supply chain continuity. Both parts carry identical EAR99 ECCN classification and HTSUS coding, maintaining regulatory equivalence. The substitute is RoHS compliant, meeting current environmental standards.

Electrical Life: Both parts are rated for 60,000 electrical cycles, ensuring equivalent operational longevity in switching applications.

Frequently Asked Questions (FAQ)

Q: Can the Electroswitch A221T11TXZQ be used as a direct replacement for the TE Connectivity 2-1571926-5 in existing applications?

A: Yes. The substitute part maintains identical electrical specifications (DPDT, On-Off-On, 6A at 125V AC, 4A at 28V DC), mechanical interface (panel mount, standard round actuator, solder lug termination, 15/32-32 bushing thread), and environmental protection (epoxy sealed terminals). Direct substitution is supported without circuit or mechanical redesign.

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

A: The primary differences are: (1) Product status—the substitute is active while the original is obsolete; (2) DC current rating—the substitute is rated 6A DC versus 4A DC on the original; (3) Operating temperature range—the substitute operates from -30°C to 90°C versus -20°C to 80°C on the original; (4) Ingress protection—the substitute includes splash proof rating; (5) Actuator length—the substitute has 11.89mm versus 17.40mm on the original. These differences represent improvements or expanded capabilities in the substitute part.

Q: Does the difference in actuator length affect mechanical compatibility?

A: Actuator length does not affect panel mount compatibility or electrical function. The actuator length difference (17.40mm versus 11.89mm) relates to the physical extension of the toggle lever above the panel surface. Both parts use identical bushing threads (15/32-32) and panel cutout specifications, ensuring mechanical fit. Actuator length selection depends on operator ergonomics and available panel space above the mounting surface.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. The substitute is RoHS compliant, meeting current environmental standards. The original part's REACH status is listed as unaffected. These classifications indicate regulatory equivalence for export and environmental compliance purposes.

Q: What is the significance of the substitute's splash proof ingress protection rating?

A: The splash proof rating on the substitute provides enhanced environmental protection compared to the original part, which has no specified ingress protection. This additional protection extends the substitute's suitability to applications with moisture exposure or washdown environments while maintaining full compatibility with dry applications where the original was used.

Q: Are the electrical life ratings equivalent?

A: Yes. Both parts are rated for 60,000 electrical cycles, indicating equivalent operational longevity and switching reliability in cyclic applications.

Q: What packaging format is available for the substitute part?

A: The Electroswitch A221T11TXZQ is supplied in bulk packaging, compared to the original part's unspecified packaging format. Bulk packaging is standard for component procurement and does not affect electrical or mechanical performance.
