Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Parallax Inc. 32398 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Frequency: 125kHz (must match exactly)
• Memory Type: Read/Write (must match exactly)
• Style: Coin form factor (must match exactly)
• Series: World Tag (same product family)

Secondary Considerations:

• Manufacturer: Parallax Inc. (same manufacturer ensures design consistency)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (environmental tolerance compatibility)
• Regulatory Compliance: REACH Unaffected, ECCN EAR99 (trade and environmental alignment)

The substitute part Parallax Inc. 32399 maintains identical frequency, memory type, style classification, and series designation. The primary dimensional difference is the increased coin diameter (30.00mm versus 20.00mm), which represents a mechanical variation within the same product category. This dimensional change may affect physical integration into existing designs and must be evaluated against specific application space constraints.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The Parallax Inc. 32398 carries Obsolete status, indicating manufacturer discontinuation. The substitute part 32399 maintains Active status, ensuring ongoing availability and manufacturer support. Selection of the 32399 provides access to current production inventory and sustained supply chain viability.

Compliance and Certification Alignment: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory consistency. The 32399 includes explicit RoHS Compliance certification, providing enhanced environmental compliance documentation compared to the main part specification.

Functional Equivalence: The 32399 maintains identical electrical specifications: 125kHz frequency, Read/Write memory type, and World Tag series classification. These parameters ensure functional interchangeability at the component level for RFID tag operations.

Mechanical Integration: The dimensional difference (30.00mm versus 20.00mm coin diameter) represents the primary substitution constraint. Physical integration feasibility depends on available mounting space and mechanical design tolerances in the target application. This parameter must be evaluated against specific enclosure and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can Parallax Inc. 32399 directly replace Parallax Inc. 32398 in existing designs?

A: Electrical and functional replacement is supported. The 32399 maintains identical 125kHz frequency, Read/Write memory type, and World Tag series specifications. Mechanical compatibility requires verification of available space for the larger 30.00mm diameter coin form factor.

Q: What is the primary difference between these two parts?

A: The primary difference is the coin diameter: 32398 measures 20.00mm, while 32399 measures 30.00mm. All electrical and functional parameters remain identical.

Q: Why is the 32398 listed as Obsolete?

A: Obsolete status indicates manufacturer discontinuation. The 32399 serves as the active production equivalent within the World Tag series.

Q: Are there any compliance differences between the parts?

A: Both parts maintain REACH Unaffected and EAR99 ECCN status. The 32399 includes explicit RoHS Compliance certification. Both share identical HTSUS classification (8543.70.9860).

Q: What packaging options are available?

A: The 32399 is available in Bulk packaging. Packaging specification for the 32398 is not provided in the technical data.

Q: Are both parts suitable for unlimited moisture exposure?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: What inventory status should be considered for procurement?

A: The 32399 shows 881 Pcs New Original In Stock, providing immediate availability. The 32398, being Obsolete, has limited procurement viability despite 703 Pcs listed in inventory.
