Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SL485K-001 are identified based on the following critical parameters that determine functional equivalence:

• Base Product Number: SL485 (common across all variants)
• Manufacturer: Synapse Wireless (same manufacturer ensures protocol and interface consistency)
• Protocol: 802.15.4 (wireless standard compatibility)
• Interface: RS-485 (serial communication standard)
• Frequency Band: 2.4GHz (RF operating band)
• RoHS Compliance: RoHS Compliant (regulatory requirement match)
• MSL Rating: 1 (Unlimited) (moisture sensitivity consistency)

The substitute parts SL485-003 and SL485-004 share the same base product number and manufacturer, indicating they are variants within the same product family with maintained electrical and mechanical compatibility for RS-485 serial interface applications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the SL485K-001, substitution with SL485-003 or SL485-004 is supported based on the following criteria:

Product Status Consideration: Both substitute parts maintain Active product status, ensuring continued manufacturer support and availability compared to the discontinued SL485K-001.

Regulatory Compliance: All three parts share identical RoHS compliance status and export control classifications (ECCN 5A002A1), maintaining regulatory requirements for deployment in equivalent applications.

Manufacturer Consistency: All parts originate from Synapse Wireless, ensuring protocol implementation consistency and interface standardization across the SNAP Link series.

Inventory Availability: SL485-003 and SL485-004 demonstrate current stock levels (900 Pcs and 805 Pcs respectively), providing supply chain continuity for new production and replacement requirements.

Selection between SL485-003 and SL485-004 should be based on specific regional or certification requirements, as SL485-004 includes CE marking designation in its description.

Frequently Asked Questions (FAQ)

Q: Can SL485-003 or SL485-004 directly replace SL485K-001 in existing designs?

A: Yes. All three parts share the same base product number (SL485), manufacturer (Synapse Wireless), RS-485 interface, and regulatory compliance status. The substitute parts are active products from the same manufacturer, indicating design continuity within the SNAP Link series.

Q: What is the difference between SL485-003 and SL485-004?

A: Both parts maintain identical electrical specifications and interface standards. SL485-004 includes CE marking certification as indicated in its product description, making it suitable for European market deployments where CE compliance is required.

Q: Are there any packaging or mechanical differences between these parts?

A: Packaging information is not provided in the available technical parameters for any of the three parts. Mechanical compatibility should be verified through detailed datasheets or physical inspection before final design integration.

Q: What compliance certifications apply to all substitute options?

A: All three parts are RoHS Compliant with MSL Rating 1 (Unlimited), share ECCN classification 5A002A1, and fall under HTSUS code 8517.62.0090. These certifications ensure regulatory equivalence for industrial and commercial applications.

Q: Why is the SL485K-001 discontinued?

A: Product discontinuation at DiGi Electronics indicates end-of-life status for this specific variant. The active status of SL485-003 and SL485-004 suggests the manufacturer has consolidated product lines within the SNAP Link series, with these variants providing equivalent functionality for ongoing applications.
