Substitute Part Grouping Explanation

Substitution of the MPS6513_D74Z is determined by the following critical parameters:

Transistor Type: Must be NPN
Current Rating: Collector current must be rated at or above 200 mA
Voltage Rating: Collector-emitter breakdown voltage must be rated at or above 30 V
Package Type: Must be through-hole TO-92 or TO-226 configuration to maintain mechanical and thermal compatibility
Operating Temperature Range: Must encompass the -55°C to 150°C specification
Saturation Characteristics: Vce saturation performance at specified base and collector currents

The substitute part 500-00001 from Parallax Inc. meets all substitution criteria. It maintains NPN polarity, supports 200 mA collector current, provides 40 V breakdown voltage (exceeding the 30 V requirement), operates across the required temperature range, and uses an identical through-hole TO-92 package. The substitute part is classified as active product status, ensuring continued availability.

Frequently Asked Questions (FAQ)

Q: Can the 500-00001 be used as a direct replacement for the MPS6513_D74Z?

A: Yes. The 500-00001 meets all critical electrical parameters (NPN type, 200 mA collector current, 40 V breakdown voltage exceeding the 30 V requirement) and uses the identical TO-92 through-hole package. No circuit modifications are necessary.

Q: What is the primary reason for substitution?

A: The MPS6513_D74Z is classified as obsolete. The 500-00001 is an active product, ensuring continued availability and supply chain support.

Q: Are there any performance differences between the two parts?

A: The 500-00001 provides superior performance in several areas: lower saturation voltage (300 mV versus 500 mV), higher power dissipation capability (1.5 W versus 625 mW), and higher breakdown voltage (40 V versus 30 V). These differences are advantageous for circuit operation.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts use the TO-92-3 (TO-226AA) through-hole package with formed leads. PCB layout and component spacing remain unchanged.

Q: Are there any compliance or certification differences?

A: Both parts carry identical ECCN EAR99 classification. No compliance changes result from substitution.
