TE Connectivity ALCOSWITCH Switches 164SZ Panel Indicator Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH Switches 164SZ is a square pilot light panel indicator without color designation, classified as an obsolete product. This component functions as a panel-mounted indicator light with a round panel cutout measuring 0.59" (14.99mm). Due to its obsolete product status, identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and replacement requirements in existing installations and legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 164SZ is determined by alignment of the following critical parameters:

Panel Cutout Compatibility: The substitute part must accommodate a round panel cutout measuring 0.59" (14.99mm) to ensure mechanical fit within existing panel installations.

Manufacturer Consistency: Substitute parts are sourced from TE Connectivity ALCOSWITCH Switches to maintain design compatibility and performance characteristics within the established product family.

Product Classification: Both the main part and substitute parts function as panel indicators within the same product category.

Regulatory and Compliance Alignment: Substitute parts maintain equivalent RoHS status (Not applicable), Moisture Sensitivity Level (MSL 1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8541.41.0000) to ensure compliance consistency.

Electrical and Mechanical Specifications: Where electrical parameters (voltage, current) and additional mechanical specifications are not provided in the component documentation, substitution is based on the documented parameters that define the physical and functional interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criterion: The 164SZ remains the specified part number for direct replacement applications where original component specifications are required.

Substitute Selection Basis: The 165TZ serves as a parametric equivalent based on matching panel cutout dimensions (0.59" / 14.99mm round), identical regulatory compliance status, and equivalent moisture sensitivity classification. Both parts share the same ECCN and HTSUS classifications, confirming alignment in export control and tariff treatment.

Obsolescence Consideration: Both the 164SZ and 165TZ carry obsolete product status. Selection between these parts should account for current inventory availability, with the 165TZ currently showing higher stock levels (1087 Pcs versus 727 Pcs).

Compliance Alignment: No RoHS applicability applies to either component. Both parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements related to moisture exposure.

Frequently Asked Questions (FAQ)

Q: What makes the 165TZ a suitable substitute for the 164SZ?

A: The 165TZ matches the 164SZ across all documented critical parameters: round panel cutout shape, 0.59" (14.99mm) cutout dimensions, identical RoHS status, MSL rating, ECCN classification, and HTSUS code. Both components are TE Connectivity ALCOSWITCH Switches panel indicators.

Q: Are there mechanical compatibility concerns when substituting the 165TZ for the 164SZ?

A: No mechanical compatibility issues exist. Both parts feature identical round panel cutout dimensions of 0.59" (14.99mm), ensuring direct fit within existing panel installations.

Q: Does the obsolete status of both parts affect substitution decisions?

A: Both parts carry obsolete product status. This status does not prevent substitution but indicates that neither part is in active production. Current inventory availability should be evaluated based on project timelines and supply requirements.

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

A: No regulatory or compliance differences exist. Both parts share identical RoHS status (Not applicable), MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8541.41.0000).

Q: What parameters are not specified for these components?

A: Lamp color, lens color, lens transparency, voltage, current, lens size, lens style, millicandela rating, wavelength peak, viewing angle, termination style, and ingress protection specifications are not provided in the component documentation. Substitution decisions are based exclusively on the parameters documented above.

Q: Which part should be selected if both are available?

A: Selection should be based on application-specific requirements and current inventory status. The 165TZ currently shows higher inventory availability (1087 Pcs) compared to the 164SZ (727 Pcs). Consult original equipment specifications to confirm the required part number for your application.
