Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMARTALPHA-868 are identified from the RF Solutions ZETAPLUS series. Substitution logic is based on the following allowed parameters:

Mounting Type Compatibility: Both substitute parts maintain through-hole or surface-mount configurations, allowing for form-factor selection based on PCB design requirements.

Manufacturer Consistency: All substitute parts are manufactured by RF Solutions, ensuring design philosophy and integration compatibility with existing RF Solutions component ecosystems.

ISM Band Operation: Substitute parts operate within ISM frequency bands, maintaining regulatory compliance for unlicensed spectrum applications.

Supply Voltage Range: Substitute parts feature wider supply voltage ranges (1.8V ~ 3.6V) compared to the fixed 3.3V requirement of SMARTALPHA-868, providing greater design flexibility.

Product Status: Substitute parts are classified as Active, ensuring ongoing availability and long-term supply chain stability.

RoHS Compliance: All substitute parts maintain RoHS compliance status, meeting environmental and regulatory requirements.

Engineering Selection Recommendations

ZETAPLUS-868-D Selection Criteria:

The ZETAPLUS-868-D is suitable for through-hole PCB designs requiring pin-compatible or footprint-compatible replacement. This part maintains Active product status, ensuring supply chain continuity. ROHS3 compliance exceeds the RoHS Compliant status of the original part. The 12-DIP Module package differs from the 16-DIP Module of SMARTALPHA-868, requiring PCB layout verification. Operating temperature range extends to -40°C ~ 85°C, providing enhanced thermal performance. Current consumption is reduced in both receiving (10mA) and transmitting (18mA) modes.

ZETAPLUS-868-SO Selection Criteria:

The ZETAPLUS-868-SO is appropriate for surface-mount PCB designs or new designs not constrained by through-hole mounting requirements. This part provides identical electrical performance to ZETAPLUS-868-D with surface-mount packaging (12-SMD Module). Active product status and ROHS3 compliance ensure regulatory alignment and supply availability. The surface-mount configuration enables higher PCB density and automated assembly processes.

Frequency Band Consideration:

Both substitute parts operate at 433MHz rather than 868MHz. Application-specific frequency requirements must be evaluated against regulatory compliance for target markets and system design specifications.

Frequently Asked Questions (FAQ)

Q: Can ZETAPLUS-868-D directly replace SMARTALPHA-868 on existing PCBs?

A: Direct replacement requires PCB layout verification. The ZETAPLUS-868-D uses a 12-DIP Module package compared to the 16-DIP Module of SMARTALPHA-868. Pin count and pinout differences necessitate design review before implementation.

Q: What is the primary advantage of selecting ZETAPLUS-868-D over ZETAPLUS-868-SO?

A: ZETAPLUS-868-D maintains through-hole mounting compatibility, suitable for existing through-hole PCB designs. ZETAPLUS-868-SO provides surface-mount packaging for new designs or high-density applications.

Q: Are the substitute parts compatible with the 3.3V supply voltage of SMARTALPHA-868?

A: Yes. Both ZETAPLUS substitute parts operate within the voltage range 1.8V ~ 3.6V, which includes the 3.3V supply voltage of the original part. The wider voltage range provides additional design flexibility.

Q: How do the current consumption specifications compare?

A: ZETAPLUS substitute parts consume less current in both receiving (10mA versus 13mA) and transmitting (18mA versus 24mA) modes, resulting in improved power efficiency.

Q: What is the significance of the frequency difference between SMARTALPHA-868 (868MHz) and ZETAPLUS substitutes (433MHz)?

A: Frequency selection depends on application requirements and regional regulatory compliance. Both frequencies operate within ISM bands. System design, antenna specifications, and regulatory certifications must align with the selected frequency band.

Q: Do the substitute parts include serial interface support?

A: Yes. Both ZETAPLUS-868-D and ZETAPLUS-868-SO include SPI and UART serial interfaces. The original SMARTALPHA-868 does not specify serial interface support, representing an enhancement in the substitute parts.

Q: What is the operating temperature range difference?

A: SMARTALPHA-868 operates from -20°C ~ 80°C. Both ZETAPLUS substitutes extend the lower limit to -40°C and upper limit to 85°C, providing enhanced thermal performance for demanding environments.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ZETAPLUS-868-D and ZETAPLUS-868-SO are ROHS3 Compliant, exceeding the RoHS Compliant status of SMARTALPHA-868.
