Key Parameters

Substitute Part Grouping Explanation

Substitution of the 114990002 is determined by strict adherence to the following core parameters: RF standard (802.15.4), protocol (Zigbee®), frequency band (2.4GHz), antenna configuration (integrated trace), and serial interface availability. All substitute parts listed maintain these mandatory criteria.

The substitute parts are grouped into two categories based on mounting technology:

Surface Mount Substitutes: ATSAMR21B18-MZ210PA, MRF24J40MA-I/RM, MRF24J40MAT-I/RM, and ZICM357SP2-1-R replace the through-hole mounting with surface mount technology. These parts are active products with current manufacturing status, addressing the obsolescence of the original part.

Substitution Criteria:

• RF Family/Standard: 802.15.4 (mandatory)
• Protocol: Zigbee® (mandatory)
• Frequency: 2.4GHz (mandatory)
• Antenna Type: Integrated, Trace (mandatory)
• Serial Interfaces: Minimum SPI support (required for core functionality)
• Voltage Supply Range: Must accommodate 3.3V operation
• RoHS Compliance: ROHS3 or equivalent (mandatory for current production)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Path: All four substitute parts satisfy the mandatory 802.15.4 Zigbee® 2.4GHz requirements with integrated trace antennas. Selection between substitutes depends on specific application requirements and PCB assembly capabilities.

ATSAMR21B18-MZ210PA (Microchip Technology): This substitute provides the closest feature alignment to the original 114990002, maintaining 256kB Flash memory and supporting both SPI and UART interfaces. Supply voltage range of 2.7V to 3.6V accommodates the original 3.3V specification. Active product status ensures long-term availability. Surface mount packaging requires PCB redesign from through-hole configuration.

MRF24J40MA-I/RM and MRF24J40MAT-I/RM (Microchip Technology): These variants are functionally identical, differing only in packaging format (Tray versus Cut Tape & Digi-Reel®). Both offer 250kbps data rate and -94dBm sensitivity, exceeding the original module's performance. SPI-only interface requires application compatibility verification. Supply voltage range of 2.4V to 3.6V provides broader operational margin. Operating temperature range of -40°C to 85°C matches industrial specifications.

ZICM357SP2-1-R (CEL MeshConnect™ Series): This substitute delivers the highest performance specifications with 20dBm power output and -103dBm sensitivity. Extended serial interface support (JTAG, SPI, UART) provides maximum flexibility. Supply voltage range of 2.1V to 3.6V offers the widest operational margin. Memory configuration differs (192kB Flash, 12kB SRAM versus 256kB Flash, 4kB EEPROM, 32kB RAM), requiring firmware assessment. Higher current consumption (58mA to 150mA transmitting) impacts power budget calculations.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. ECCN classifications vary between substitutes; verify export control requirements for specific applications.

Frequently Asked Questions (FAQ)

Q: Can the 114990002 be directly replaced with any of these substitute parts without PCB modification?

A: No. The original 114990002 uses through-hole 20-DIP packaging, while all substitute parts employ surface mount technology. PCB redesign is required to accommodate the different mounting footprints. However, all substitutes maintain electrical compatibility with 802.15.4 Zigbee® protocol and 2.4GHz frequency operation.

Q: Which substitute part offers the best performance upgrade?

A: The ZICM357SP2-1-R provides the highest performance specifications with 20dBm power output (versus -1dBm to 0dBm in other substitutes) and -103dBm sensitivity (versus -94dBm). However, this comes with increased current consumption and different memory architecture. Selection depends on application power budget and firmware compatibility requirements.

Q: Are all substitute parts suitable for industrial temperature applications?

A: The MRF24J40MA-I/RM and MRF24J40MAT-I/RM support -40°C to 85°C operating temperature. The ATSAMR21B18-MZ210PA supports -40°C to 125°C, providing extended high-temperature capability. The ZICM357SP2-1-R supports -40°C to 85°C. Verify specific application temperature requirements before selection.

Q: What is the primary difference between MRF24J40MA-I/RM and MRF24J40MAT-I/RM?

A: These parts are electrically and functionally identical. The difference is packaging format: MRF24J40MA-I/RM is supplied in Tray packaging, while MRF24J40MAT-I/RM is supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly line equipment and volume requirements.

Q: Does the ATSAMR21B18-MZ210PA support I2C interface like the original 114990002?

A: No. The ATSAMR21B18-MZ210PA supports SPI and UART interfaces only. If I2C communication is required for the application, this substitute is not suitable. The ZICM357SP2-1-R supports JTAG, SPI, and UART but not I2C.

Q: What are the memory differences between substitutes?

A: The 114990002 and ATSAMR21B18-MZ210PA both provide 256kB Flash memory. The ZICM357SP2-1-R provides 192kB Flash with 12kB SRAM. The MRF24J40 series does not specify memory size. Firmware size and data storage requirements must be evaluated against available memory in each substitute.

Q: Are all substitute parts currently in active production?

A: Yes. All four substitute parts have Active product status, ensuring long-term availability and manufacturing support. The original 114990002 is classified as Obsolete, making substitution necessary for new designs and ongoing production.

Q: What is the impact of different supply voltage ranges on system design?

A: All substitutes accept 3.3V operation. The ZICM357SP2-1-R offers the widest range (2.1V to 3.6V), allowing operation at lower voltages. The MRF24J40 series (2.4V to 3.6V) and ATSAMR21B18-MZ210PA (2.7V to 3.6V) provide narrower ranges. Verify power supply design compatibility with selected substitute.

Q: Which substitute requires the least firmware modification?

A: The ATSAMR21B18-MZ210PA maintains the closest feature set to the original 114990002, including 256kB Flash memory and dual serial interface support (SPI, UART). However, loss of I2C interface may require application code changes. Firmware assessment is necessary for all substitutes.
