XA-Z16-CS3RL Equivalent & Substitute Parts

Part Overview

The XA-Z16-CS3RL is an RF Transceiver module from Digi's XBee® series, designed for ZigBee™ 2.4GHz wireless communication applications. This module operates at 2.4GHz using Direct Sequence Spread Spectrum (DSSS) modulation with RS-485 interface connectivity and achieves a maximum data rate of 250kbps. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, legacy system support, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The XA-Z14-CS3PH-A qualifies as a substitute for the XA-Z16-CS3RL based on the following core compatibility parameters:

Matching Parameters:

• Manufacturer: Digi (same manufacturer ecosystem)
• Frequency: 2.4GHz (identical operating frequency)
• Modulation/Protocol: DSSS (same modulation standard)
• Interface: RS-485 (same serial interface type)
• Data Rate (Max): 250kbps (identical maximum throughput)
• Function: Transceiver, ZigBee™ (same functional classification)
• MSL Rating: 1 (Unlimited) (identical moisture sensitivity level)

Substitution Basis: Both modules operate within the ZigBee™ 2.4GHz protocol framework with RS-485 interface connectivity. The XA-Z14-CS3PH-A belongs to the XBee-Pro® series, which maintains protocol and interface compatibility while offering enhanced performance characteristics. Substitution is valid where the enhanced specifications of the XA-Z14-CS3PH-A do not conflict with system design constraints.

Parameter Comparison

Engineering Selection Recommendations

Substitution Validity: The XA-Z14-CS3PH-A is a valid substitute for the XA-Z16-CS3RL where system design accommodates the following differences:

1. Power Supply Architecture: The XA-Z14-CS3PH-A requires 9V ~ 30V supply versus the XA-Z16-CS3RL's 3V ~ 6V range. System power delivery must be redesigned or verified to support the higher voltage requirement.

2. Performance Enhancement: The XA-Z14-CS3PH-A provides superior receiver sensitivity (-102dBm vs. -96dBm) and transmit power (17dBm vs. 1dBm). These enhancements are backward-compatible with systems designed for the lower-performance XA-Z16-CS3RL.

3. Compliance Status: The XA-Z14-CS3PH-A carries RoHS Compliant certification, providing regulatory advantage for new deployments or system updates.

4. Packaging: The XA-Z14-CS3PH-A is supplied in Bulk packaging, whereas the XA-Z16-CS3RL packaging is unspecified. Verify packaging requirements for your procurement process.

Obsolescence Consideration: Both modules are obsolete products. Substitution decisions should prioritize long-term component availability and supply chain stability through authorized Digi distributors.

Frequently Asked Questions (FAQ)

Q: Can the XA-Z14-CS3PH-A directly replace the XA-Z16-CS3RL in existing systems?

A: Direct replacement requires verification of power supply compatibility. The XA-Z14-CS3PH-A operates at 9V ~ 30V, while the XA-Z16-CS3RL operates at 3V ~ 6V. If your system power architecture supports the higher voltage range, the XA-Z14-CS3PH-A is functionally compatible. RS-485 interface pinout and protocol compatibility are maintained.

Q: What are the key differences between these two modules?

A: Both modules share identical frequency (2.4GHz), modulation (DSSS), interface (RS-485), and data rate (250kbps) specifications. The XA-Z14-CS3PH-A provides enhanced receiver sensitivity (-102dBm vs. -96dBm) and transmit power (17dBm vs. 1dBm), and requires higher supply voltage (9V ~ 30V vs. 3V ~ 6V).

Q: Are there any compliance differences between these parts?

A: The XA-Z14-CS3PH-A is RoHS Compliant, while the XA-Z16-CS3RL RoHS status is not specified. Both modules have identical MSL ratings (1 - Unlimited) and REACH Unaffected status.

Q: What is the impact of the higher power output on system design?

A: The XA-Z14-CS3PH-A's 17dBm output (versus 1dBm) extends transmission range and improves link margin. This enhancement does not negatively impact systems designed for lower power output; however, verify that your RF design and antenna configuration are appropriate for the higher transmit power.

Q: How does the improved sensitivity affect compatibility?

A: The XA-Z14-CS3PH-A's -102dBm sensitivity (versus -96dBm) improves receiver performance and extends communication range. This is a backward-compatible enhancement that does not create incompatibility with existing system designs.

Q: Are both modules still available for purchase?

A: Both modules are obsolete products. Availability is limited to authorized Digi distributors and inventory liquidation channels. Verify current stock status and lead times before finalizing procurement decisions.
