Substitute Part Grouping Explanation

Substitution of the MP6KE39AE3 is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 33.3V
• Voltage - Breakdown (Min): 37.1V
• Voltage - Clamping (Max) @ Ipp: 53.9V
• Current - Peak Pulse (10/1000µs): 11.2A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Type: Zener

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Base Product Number: P6KE39

The substitute part P6KE39A, manufactured by Taiwan Semiconductor Corporation, satisfies all electrical equivalence criteria and maintains through-hole mounting compatibility. Substitution is valid where packaging format differences (T-18 versus DO-15) are accommodated by circuit board design and assembly processes.

Engineering Selection Recommendations

MP6KE39AE3 (Microchip Technology):

• Select this part for applications requiring military-grade qualification under MIL-PRF-19500
• Suitable for designs with established temperature operating range requirements of -65°C to 150°C
• Appropriate where RoHS non-compliance is acceptable or required by specification
• T-18 axial package format is specified for existing circuit board layouts

P6KE39A (Taiwan Semiconductor Corporation):

• Select this part where ROHS3 compliance is a design requirement
• Suitable for applications where DO-15 axial package format is compatible with circuit board design
• Appropriate where military-grade qualification is not required
• Higher inventory availability (17,985 units) supports rapid procurement timelines
• Cut Tape packaging format accommodates automated assembly processes

Both parts maintain identical electrical performance across all critical transient voltage suppression parameters and are functionally interchangeable from an electrical standpoint, provided packaging and compliance requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can P6KE39A be used as a direct replacement for MP6KE39AE3?

A: P6KE39A is electrically equivalent to MP6KE39AE3 across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power. Substitution is valid provided the DO-15 package format is compatible with the circuit board layout and the ROHS3 compliance status meets design requirements. Military-grade qualification is not transferred with this substitution.

Q: What are the package format differences between these parts?

A: MP6KE39AE3 uses a T-18 axial package, while P6KE39A uses a DO-15 (DO-204AC) axial package. Both are through-hole axial configurations, but physical dimensions and lead spacing differ. Circuit board design must accommodate the specific package format selected.

Q: Are there operating temperature differences between these parts?

A: MP6KE39AE3 specifies an operating temperature range of -65°C to 150°C. P6KE39A does not provide an operating temperature specification in the available data. For applications requiring defined temperature performance, MP6KE39AE3 is the specified choice.

Q: What compliance differences exist between these parts?

A: MP6KE39AE3 is RoHS non-compliant and carries military-grade qualification under MIL-PRF-19500. P6KE39A is ROHS3 compliant and does not carry military qualification. Design requirements for environmental compliance and military specifications determine which part is appropriate.

Q: How do packaging formats affect component selection?

A: MP6KE39AE3 is supplied in Bulk packaging, while P6KE39A is supplied in Cut Tape (CT) format. Bulk packaging is typical for manual assembly or small-quantity procurement. Cut Tape format supports automated pick-and-place assembly processes. Selection depends on assembly methodology and procurement volume requirements.

Q: Are the electrical performance specifications identical?

A: Yes. Both parts share identical specifications for reverse standoff voltage (33.3V), breakdown voltage (37.1V), clamping voltage (53.9V), peak pulse current (11.2A), and peak pulse power (600W). Electrical performance in transient voltage suppression applications is equivalent.
