SL485K-002 Equivalent & Substitute Parts

Part Overview

The SL485K-002 is a SNAP Link Serial Adapter for RS485 communications, manufactured by Synapse Wireless. This RF adapter operates at 2.4GHz using the 802.15.4 SNAP protocol and supports serial interfaces including RS-232, RS-422, and RS-485 with a maximum data rate of 2Mbps. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, upgrades, and new deployments requiring compatible functionality.

Substitute Part Grouping Explanation

Substitute parts for the SL485K-002 are identified based on the following critical parameters that determine functional compatibility:

• Base Product Number: SL485 (common platform)
• Manufacturer: Synapse Wireless (same manufacturer ecosystem)
• Protocol Support: 802.15.4 and SNAP compatibility
• Serial Interface: RS-485 capability
• Frequency Band: 2.4GHz operation
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• ECCN and HTSUS Classification: Identical regulatory codes

The substitute parts SL485-003 and SL485-004 share the same base product number and maintain compatibility with the core SL485 platform. Both substitutes are active products with current manufacturing status, providing viable alternatives to the obsolete SL485K-002.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the SL485K-002, the following selection criteria apply:

SL485-003 is the primary substitute option. It maintains active product status with current manufacturing support and is RoHS compliant, meeting modern environmental and regulatory requirements.

SL485-004 is an alternative substitute with identical core specifications to SL485-003. The designation includes CE marking compliance, indicating conformance to European Union regulatory requirements. This variant is suitable for deployments requiring explicit CE certification documentation.

Both substitutes share identical regulatory classifications (ECCN and HTSUS codes) with the original part, ensuring consistent export and import compliance. The transition from obsolete to active product status ensures long-term supply chain stability and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can SL485-003 or SL485-004 directly replace SL485K-002 in existing systems?

A: Yes. Both substitutes share the same base product number (SL485) and maintain compatibility with the SNAP Link platform. They support identical serial interfaces (RS-485) and operate under the same protocol specifications (802.15.4, SNAP).

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

A: Both parts are functionally equivalent. SL485-004 includes CE marking compliance, indicating certification for European Union regulatory requirements. Selection between them depends on regional deployment requirements and certification documentation needs.

Q: Are there packaging differences between these parts?

A: Packaging information is not specified in the available technical data for any of these part numbers. Contact the manufacturer for specific packaging details if this is a critical requirement for your application.

Q: Why is RoHS compliance listed for substitutes but not the original part?

A: The SL485K-002 is obsolete and predates current RoHS compliance documentation standards. The active substitutes (SL485-003 and SL485-004) are manufactured to current RoHS requirements.

Q: Are the electrical specifications identical across all three parts?

A: The detailed electrical specifications (frequency, data rate, sensitivity, power output, and supply voltage) are not provided for the substitute parts in the available technical documentation. Verify these parameters with the manufacturer if they are critical to your application requirements.

Q: What is the inventory status for these parts?

A: SL485K-002 has 960 pieces in stock (obsolete status). SL485-003 has 900 pieces available. SL485-004 has 805 pieces available. Inventory levels are subject to change; confirm current availability with your supplier.
