KAPPA-T868-SO RF Transceiver Module Equivalent & Substitute Parts

Part Overview

The KAPPA-T868-SO is a General ISM < 1GHz transceiver module operating at 868MHz, designed for surface mount applications. This module is classified as Obsolete product status, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations. The KAPPA-T868-SO provides integrated transmit and receive functionality with a data rate of 9.6kbps and operates across a supply voltage range of 1.8V to 3.6V. Due to its obsolete classification, alternative components with compatible electrical and mechanical parameters are necessary for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KAPPA-T868-SO is determined by the following critical parameters:

Frequency Compatibility: The substitute part must operate at 868MHz to maintain ISM band compliance and system interoperability.

Voltage Supply Range: The substitute must support the 1.8V to 3.6V supply voltage range to ensure compatibility with existing power delivery systems.

Mounting and Package: The substitute must utilize Surface Mount technology with a 12-SMD Module package configuration to maintain PCB layout compatibility.

RF Performance Characteristics: The substitute must provide comparable power output and sensitivity specifications to ensure equivalent link budget and system performance.

Regulatory Compliance: The substitute must maintain RoHS compliance status and appropriate ECCN/HTSUS classifications for the ISM transceiver category.

The ZPT-8TS is identified as a manufacturer-recommended substitute based on these parameters. While the ZPT-8TS functions as a transmitter-only module (versus the transceiver functionality of the KAPPA-T868-SO), it meets the core electrical and mechanical compatibility criteria for 868MHz ISM band applications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The KAPPA-T868-SO is classified as Obsolete, while the ZPT-8TS is Active. Selection of the ZPT-8TS provides access to an actively manufactured component with ongoing supplier support and availability.

Compliance and Certification: Both components maintain RoHS compliance. The ZPT-8TS carries ROHS3 Compliant status, representing the current RoHS standard revision, whereas the KAPPA-T868-SO carries RoHS Compliant status. Both components are classified under HTSUS 8517.62.0090 for ISM transceiver modules.

Electrical Performance: The ZPT-8TS provides 15dBm output power compared to the KAPPA-T868-SO's 13dBm, representing a 2dBm improvement in transmit capability. The ZPT-8TS demonstrates significantly reduced transmit current consumption at 24mA versus 200mA, resulting in improved power efficiency for battery-powered applications.

Operating Temperature Range: The ZPT-8TS supports an extended operating temperature range of -20°C to 85°C, compared to the KAPPA-T868-SO's -20°C to 55°C range, providing broader environmental compatibility.

Functional Scope: The ZPT-8TS is a transmitter-only module, whereas the KAPPA-T868-SO provides integrated transceiver functionality. System designs requiring receive capability must evaluate alternative solutions or implement separate receive modules.

Frequently Asked Questions (FAQ)

Q: Can the ZPT-8TS directly replace the KAPPA-T868-SO in existing designs?

A: Direct replacement is possible only for applications requiring transmit-only functionality at 868MHz. The KAPPA-T868-SO provides integrated transceiver capability (transmit and receive), while the ZPT-8TS functions as a transmitter module only. Designs requiring bidirectional communication must implement alternative receive solutions.

Q: Are the supply voltage requirements identical between these components?

A: Yes. Both the KAPPA-T868-SO and ZPT-8TS operate across the 1.8V to 3.6V supply voltage range, ensuring compatibility with existing power delivery circuits.

Q: What are the package compatibility implications?

A: Both components utilize 12-SMD Module surface mount packaging, maintaining identical PCB footprint and mounting requirements. No layout modifications are necessary for package compatibility.

Q: How do the power output specifications compare?

A: The ZPT-8TS provides 15dBm output power versus the KAPPA-T868-SO's 13dBm. This 2dBm increase in transmit power improves link budget by approximately 58% in linear terms, enhancing communication range and reliability.

Q: What is the significance of the reduced current consumption in the ZPT-8TS?

A: The ZPT-8TS transmit current of 24mA represents a 88% reduction compared to the KAPPA-T868-SO's 200mA. This substantial reduction in power consumption is critical for battery-powered and energy-constrained applications, extending operational lifetime.

Q: Are there regulatory or compliance differences between these components?

A: Both components maintain RoHS compliance. The ZPT-8TS carries ROHS3 Compliant status (current standard), while the KAPPA-T868-SO carries RoHS Compliant status. Both are classified under HTSUS 8517.62.0090. The ZPT-8TS ECCN classification is 5A991G, while the KAPPA-T868-SO is EAR99.

Q: What is the availability status of each component?

A: The KAPPA-T868-SO is Obsolete with 1110 pieces in stock. The ZPT-8TS is Active with 886 pieces in stock, providing ongoing manufacturing availability and supply chain continuity.
