MPY634KP Equivalent & Substitute Parts

Part Overview

The MPY634KP is a 4-quadrant analog multiplier manufactured by Texas Instruments in a 14-DIP package. This linear integrated circuit performs analog multiplication operations and is classified as an active product with full production support. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPY634KP is determined by the following critical parameters:

• Function: Both parts must perform 4-quadrant analog multiplication
• Quadrant Operation: 4-quadrant capability is mandatory for functional equivalence
• Package Compatibility: 14-pin DIP-based packages (14-DIP or 14-CDIP) with 0.300" (7.62mm) pitch are acceptable for PCB layout compatibility
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be maintained
• Product Status: Active status ensures ongoing manufacturer support and availability

The AD632BD meets all substitution criteria as a 4-quadrant analog multiplier/divider in a 14-CDIP package with equivalent pin pitch and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The AD632BD is a direct substitute for the MPY634KP based on the following criteria:

• Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment
• Both parts are classified as active products with ongoing manufacturer support
• Both parts operate as 4-quadrant analog multipliers with identical quadrant functionality
• Package compatibility is maintained through equivalent 14-pin DIP-based form factors with identical 0.300" (7.62mm) pitch
• Both parts share identical ECCN classification (EAR99), confirming export control equivalence

Selection between these parts is determined by availability, supply chain requirements, and design flexibility needs rather than functional or electrical constraints.

Frequently Asked Questions (FAQ)

Q: Can the AD632BD directly replace the MPY634KP in existing designs?

A: Yes. Both parts are 4-quadrant analog multipliers in mechanically compatible 14-pin DIP packages with 0.300" (7.62mm) pitch. Pin configuration compatibility must be verified against your specific schematic.

Q: What is the difference between 14-DIP and 14-CDIP packaging?

A: Both are 14-pin dual inline packages with identical 0.300" (7.62mm) pitch and footprint. The primary difference is material composition and thermal characteristics. Both are suitable for standard DIP sockets and PCB layouts designed for 14-pin DIP components.

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) codes. Regulatory requirements are equivalent.

Q: What does 4-quadrant operation mean?

A: 4-quadrant operation indicates the multiplier functions correctly when both input signals are positive, negative, or mixed polarity. This is the standard operating mode for analog multiplier integrated circuits.

Q: Is the AD632BD's divider function relevant for MPY634KP substitution?

A: The divider function is an additional capability of the AD632BD. For MPY634KP substitution, only the 4-quadrant multiplier function is required. The divider capability does not affect compatibility or substitution validity.
