MPY534LD Equivalent & Substitute Parts

Part Overview

The MPY534LD is a precision analog multiplier manufactured by Texas Instruments, designed for 4-quadrant multiplication operations in linear signal processing applications. The device is packaged in a 14-CDIP configuration with unlimited moisture sensitivity rating. As an obsolete product, identifying functionally equivalent alternatives is essential for system redesign, legacy equipment maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPY534LD is determined by the following critical parameters:

• Function: Analog Multiplier or Analog Multiplier/Divider capability
• Number of Bits/Stages: 4-Quadrant operation
• Package / Case: 14-CDIP (0.300", 7.62mm) form factor
• Supplier Device Package: 14-CDIP pin configuration
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• HTSUS Code: 8542.39.0001 (commodity classification alignment)

The AD534LD meets all substitution criteria, providing functional equivalence with identical package specifications and moisture sensitivity characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AD534LD is the direct substitute for the obsolete MPY534LD. Both devices share identical package specifications (14-CDIP), moisture sensitivity ratings (MSL 1), and regulatory classifications (ECCN EAR99, HTSUS 8542.39.0001). The AD534LD offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and systems requiring modern regulatory alignment. The AD534LD's extended functionality as an Analog Multiplier/Divider provides operational flexibility beyond the MPY534LD's multiplier-only capability while maintaining full pin-compatible substitution.

Frequently Asked Questions (FAQ)

Q: Can the AD534LD directly replace the MPY534LD in existing designs?

A: Yes. Both devices use the 14-CDIP package with identical pin configurations and MSL 1 moisture sensitivity ratings. Direct socket substitution is supported.

Q: What is the primary reason for substituting the MPY534LD?

A: The MPY534LD is obsolete. The AD534LD is an active product from Analog Devices Inc. with equivalent 4-quadrant analog multiplication capability and identical packaging.

Q: Are there compliance differences between these parts?

A: The AD534LD is ROHS3 compliant, while the MPY534LD is RoHS non-compliant. Both share identical REACH and ECCN classifications.

Q: Does the AD534LD's divider function affect compatibility?

A: No. The AD534LD's additional divider capability does not impact multiplier operation. The device remains fully compatible with circuits designed for the MPY534LD's multiplication function.

Q: Are moisture sensitivity levels identical?

A: Yes. Both the MPY534LD and AD534LD carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions for storage or handling.
