Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NSD-1202 is determined by strict parametric matching across the following critical criteria:

Electrical Parameters: Supply voltage range (2.8V ~ 5.5V), load voltage range (24V ~ 40V), output current (25mA), and interface protocol (I2C) must be identical.

Functional Parameters: Motor type (Piezo), output configuration (Half Bridge with 4 outputs), and integrated control and power stage functionality must match exactly.

Physical Parameters: Package type (16-VQFN Exposed Pad), mounting method (Surface Mount), and device package designation (16-QFN 4x4) must be identical.

Environmental Parameters: Operating temperature range (-40°C ~ 125°C) and moisture sensitivity level (MSL 3) must be maintained.

Technology: CMOS technology platform must be consistent.

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The NSD-1202-ASST is a direct parametric equivalent to the NSD-1202 across all electrical, functional, physical, and environmental specifications. All critical parameters match exactly, including supply voltage range, load voltage range, output current, I2C interface, piezoelectric motor control function, half-bridge output configuration, CMOS technology, and package designation.

The primary distinction between these parts is product status: the NSD-1202 is classified as obsolete, while the NSD-1202-ASST maintains active product status. Additionally, the NSD-1202-ASST carries RoHS Compliance certification, providing enhanced environmental and regulatory alignment for new designs and long-term production continuity.

Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8542.39.0001), ensuring consistent regulatory treatment in supply chain operations.

For applications currently using the NSD-1202, the NSD-1202-ASST provides a direct drop-in replacement with no circuit redesign required. The active product status and RoHS compliance of the NSD-1202-ASST make it the appropriate selection for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the NSD-1202-ASST be used as a direct replacement for the NSD-1202 in existing designs?

A: Yes. The NSD-1202-ASST is a parametric equivalent with identical electrical specifications, functional characteristics, and package configuration. No circuit modifications are required for substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: supply voltage range (2.8V ~ 5.5V), load voltage range (24V ~ 40V), output current (25mA), I2C interface, piezoelectric motor type, half-bridge output configuration (4 outputs), CMOS technology, operating temperature range (-40°C ~ 125°C), package type (16-VQFN Exposed Pad), and device package (16-QFN 4x4).

Q: Why is the NSD-1202 classified as obsolete?

A: The NSD-1202 has reached end-of-life status. The NSD-1202-ASST is the active equivalent that maintains all functional and electrical specifications while providing ongoing availability and RoHS compliance.

Q: Are there any differences in pin configuration or footprint between these parts?

A: No. Both parts use the 16-QFN (4x4) package with 16-VQFN Exposed Pad configuration, ensuring identical PCB footprints and pin assignments.

Q: What is the significance of RoHS Compliance on the NSD-1202-ASST?

A: RoHS Compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. This is relevant for designs targeting markets with environmental compliance requirements.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have MSL 3 (168 Hours) rating, indicating identical moisture handling and storage requirements.

Q: Can inventory of NSD-1202 be used interchangeably with NSD-1202-ASST in production?

A: Yes, from a technical standpoint. However, inventory management should account for the obsolete status of the NSD-1202 and transition to the active NSD-1202-ASST for long-term supply chain stability.
