Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 2-1571926-1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-Off-Mom
• AC current rating must be 6A minimum
• AC voltage rating must be 125V minimum
• DC voltage rating must be 28V minimum
• Electrical life must be 60,000 cycles minimum

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
• Features must include epoxy sealed terminals

The Electroswitch A231T1TZQ satisfies all electrical and mechanical equivalence criteria. Both parts share identical circuit configuration, switch function, current and voltage ratings, termination style, bushing thread specification, and terminal sealing features. Both are rated for 60,000 electrical cycles and feature standard round actuators suitable for panel-mount applications.

Parameter Comparison

Engineering Selection Recommendations

The Electroswitch A231T1TZQ is a direct functional equivalent for the obsolete TE Connectivity ALCOSWITCH 2-1571926-1. Both parts meet identical electrical specifications for DPDT switching at 6A/125V AC and 28V DC with 60,000-cycle electrical life ratings.

Compliance Advantages of the Substitute: The Electroswitch A231T1TZQ carries active product status with RoHS compliance certification, whereas the original part is obsolete with unspecified RoHS status. Both parts share EAR99 ECCN classification and identical HTSUS codes, indicating equivalent regulatory treatment for export and trade purposes.

Physical Considerations: The substitute part features a longer actuator length (17.45mm versus 11.50mm). This difference requires verification against panel cutout geometry and actuator clearance envelopes in the target application. The substitute's wider operating temperature range (-30°C to 90°C versus -20°C to 80°C) provides enhanced thermal performance margin.

Performance Characteristics: The Electroswitch A231T1TZQ provides equal or superior electrical performance with DC current rating of 6A compared to the original 4A DC rating. Identical electrical life, termination style, bushing thread specification, and terminal sealing features ensure functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the Electroswitch A231T1TZQ directly replace the TE Connectivity 2-1571926-1 in existing applications?

A: The Electroswitch A231T1TZQ is electrically and mechanically equivalent for DPDT switching applications at the specified voltage and current ratings. The primary consideration is the longer actuator length (17.45mm versus 11.50mm), which must be verified against panel cutout dimensions and actuator travel space in the specific installation.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by equivalence in circuit configuration (DPDT), switch function (On-Off-Mom), current ratings (6A AC minimum), voltage ratings (125V AC and 28V DC), mounting type (panel mount), actuator type (standard round), termination style (solder lug), bushing thread (15/32-32), and terminal sealing features (epoxy sealed).

Q: Does the substitute part meet modern compliance standards?

A: The Electroswitch A231T1TZQ carries RoHS compliance certification and active product status. Both the original and substitute parts share identical EAR99 ECCN and HTSUS classifications, indicating equivalent regulatory treatment.

Q: Are there any electrical performance differences between the two parts?

A: Both parts are rated for 6A at 125V AC and 28V DC with 60,000-cycle electrical life. The Electroswitch A231T1TZQ provides a higher DC current rating (6A versus 4A), representing equal or superior performance for DC applications.

Q: What packaging considerations apply to the substitute part?

A: The Electroswitch A231T1TZQ is supplied in bulk packaging, whereas the original part packaging specification is not provided. Bulk packaging is standard for industrial toggle switch distribution and does not affect electrical or mechanical performance.

Q: How does the operating temperature range differ?

A: The Electroswitch A231T1TZQ operates across -30°C to 90°C, compared to the original part's -20°C to 80°C range. The substitute provides a 10°C lower minimum and 10°C higher maximum operating temperature, offering expanded thermal performance margin for temperature-sensitive applications.
