ZSDA0254P Equivalent & Substitute Parts

Part Overview

The ZSDA0254P is a PIR (Passive Infrared) motion sensor manufactured by Zilog as part of the ZMOTION® series. This component is classified as obsolete, with 805 units available in new original stock. The sensor operates on a digital output architecture with a supply voltage range of 2.7V to 3.6V and features external trigger capability. Due to its obsolete status, identifying functionally compatible substitute components is essential for ongoing system design and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZSDA0254P is determined by the following critical parameters:

• Sensor Type: PIR (Passive Infrared) technology
• Manufacturer: Zilog ZMOTION® series
• RoHS Compliance: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The ZSBG323671 qualifies as a direct substitute based on shared sensor technology (PIR), identical manufacturer (Zilog), matching compliance certifications (ROHS3, REACH Unaffected), and equivalent moisture sensitivity rating. Both components operate within the ZMOTION® product family and maintain consistent regulatory compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

The ZSBG323671 is an active production component within the Zilog ZMOTION® family, providing continuity for applications currently using the obsolete ZSDA0254P. Both parts maintain identical RoHS3 compliance and REACH unaffected status, ensuring regulatory consistency across design transitions.

The substitute part operates across an extended supply voltage range (3V ~ 10V) compared to the main part (2.7V ~ 3.6V), providing greater flexibility in power supply design. The ZSBG323671 features dual-element PIR architecture with EMI compensation and high sensitivity characteristics, packaged in a TO-5 variant with three leads and lens top metal can construction.

Selection of the ZSBG323671 is supported by active product status, ensuring long-term availability and supply chain stability for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the ZSBG323671 directly replace the ZSDA0254P in existing designs?

A: Both components are PIR motion sensors within the Zilog ZMOTION® series with matching compliance certifications. However, design integration requires evaluation of output type differences (digital versus analog) and supply voltage range compatibility (2.7V ~ 3.6V versus 3V ~ 10V).

Q: What is the primary difference between these two motion sensors?

A: The ZSDA0254P provides digital output with a narrow supply voltage range, while the ZSBG323671 delivers analog output with extended voltage capability and dual-element PIR architecture with EMI compensation.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ZSDA0254P and ZSBG323671 are ROHS3 compliant and REACH unaffected, maintaining consistent environmental and regulatory compliance.

Q: What packaging format does the substitute part use?

A: The ZSBG323671 is packaged in a TO-5 variant with three leads and a lens top metal can configuration, suitable for through-hole mounting applications.

Q: Why is the ZSDA0254P listed as obsolete?

A: The ZSDA0254P has reached end-of-life status within Zilog's product portfolio. The ZSBG323671 represents the active production alternative within the ZMOTION® sensor family.
