Key Parameters

Substitute Part Grouping Explanation

Substitution of the 165TZ panel indicator is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Panel cutout shape classification (Round)
• Panel cutout dimensional specification (0.59" / 14.99mm)
• Product category (Panel Indicator)
• Manufacturer source (TE Connectivity ALCOSWITCH Switches)
• Moisture sensitivity level (MSL 1 - Unlimited)
• Regulatory compliance classification (ECCN EAR99, HTSUS 8541.41.0000)

The 164SZ qualifies as a parametric equivalent based on matching panel cutout geometry and dimensions, enabling direct mechanical substitution in panel mounting applications. Both components share identical environmental ratings and regulatory classifications, confirming compatibility within the same application context.

Parameter Comparison

Engineering Selection Recommendations

Both the 165TZ and 164SZ components are classified as obsolete products. Selection between these parts should be based on the following engineering considerations:

Inventory Availability: The 165TZ maintains higher stock levels (1087 units) compared to the 164SZ (727 units), providing greater availability for immediate procurement requirements.

Regulatory Compliance: Both components share identical regulatory classifications (ECCN EAR99, HTSUS 8541.41.0000) and RoHS status (Not applicable), confirming equivalent compliance posture for export and supply chain documentation.

Environmental Specifications: Both parts maintain MSL 1 (Unlimited) moisture sensitivity ratings, indicating equivalent performance in standard industrial environments without specialized moisture control requirements.

Mechanical Compatibility: Identical panel cutout specifications (0.59" / 14.99mm round) ensure direct mechanical interchangeability in existing panel mounting designs without modification to enclosure geometry.

Frequently Asked Questions (FAQ)

Q: Can the 164SZ directly replace the 165TZ in existing applications?

A: The 164SZ provides mechanical compatibility through matching panel cutout dimensions and shape. Both components are classified as panel indicators with identical environmental and regulatory specifications. Direct substitution is supported by the aligned critical parameters.

Q: What are the key differences between the 165TZ and 164SZ?

A: The primary distinction lies in the product descriptions: the 165TZ is designated as a rectangular pilot light with splash-proof design, while the 164SZ is described as a square pilot light without color specification. Both maintain identical panel cutout geometry and environmental ratings.

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

A: No. Both the 165TZ and 164SZ share identical RoHS status (Not applicable), ECCN classification (EAR99), and HTSUS codes (8541.41.0000), confirming equivalent regulatory and compliance standing.

Q: Which part should be selected for new designs?

A: Both components are classified as obsolete. For new design applications, consultation with TE Connectivity ALCOSWITCH Switches is necessary to identify current-production panel indicator alternatives that may offer enhanced availability and extended product lifecycle support.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 (Unlimited) indicates that both components have no moisture sensitivity restrictions and do not require specialized moisture control during storage, handling, or installation. This classification applies to standard industrial environments.

Q: Are there inventory considerations for part selection?

A: The 165TZ maintains higher current inventory (1087 units) relative to the 164SZ (727 units). For applications requiring immediate availability, the 165TZ presents a more favorable procurement position.
