Key Parameters

Substitute Part Grouping Explanation

Substitution of the DEBF33D103ZA2B is determined by the following critical parameters:

• Capacitance Value: 10000 pF (exact match required)
• Voltage Rating: 2000V (2kV) minimum (equal or higher acceptable)
• Mounting Configuration: Through Hole, Radial, Disc (physical compatibility)
• Tolerance: Acceptable range for circuit function (-20%, +80% or tighter)
• Temperature Coefficient: F or Z5U (functional equivalence in high-voltage applications)
• Compliance: RoHS3 compliance maintained

The substitute part S103M69Z5UP63K7R meets these criteria with matching capacitance, voltage rating, mounting type, and compliance status. The Z5U temperature coefficient provides broader operating temperature range (-30°C ~ 125°C) compared to the F coefficient of the original part.

Parameter Comparison

Engineering Selection Recommendations

The S103M69Z5UP63K7R is a direct functional substitute for the obsolete DEBF33D103ZA2B based on electrical equivalence. Both components maintain identical capacitance (10000 pF) and voltage rating (2000V), with RoHS3 compliance preserved. The substitute part features a Z5U temperature coefficient with extended operating range (-30°C ~ 125°C) compared to the original F coefficient (-25°C ~ 85°C), providing enhanced thermal performance for applications requiring broader temperature operation.

Physical dimensions differ, with the substitute part measuring 0.689" diameter and 0.878" height compared to 0.472" diameter and 0.591" height of the original. PCB layout and mechanical clearance verification is required prior to implementation. The substitute part is currently in active production status with established supply availability (6560 pcs in stock), ensuring long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can S103M69Z5UP63K7R be used as a direct replacement for DEBF33D103ZA2B?

A: Electrical substitution is valid. Both parts share identical capacitance (10000 pF) and voltage rating (2000V). Physical dimensions differ; the substitute is larger (0.689" diameter vs. 0.472" diameter). PCB layout compatibility must be verified before implementation.

Q: What is the difference between F and Z5U temperature coefficients?

A: F coefficient specifies capacitance change over -25°C to 85°C operating range. Z5U coefficient specifies change over -30°C to 125°C range. Z5U provides broader temperature operation with tighter tolerance (±20% vs. -20%, +80%).

Q: Are both parts RoHS3 compliant?

A: Yes. Both DEBF33D103ZA2B and S103M69Z5UP63K7R are RoHS3 compliant, meeting environmental and regulatory requirements.

Q: What is the lead spacing difference?

A: DEBF33D103ZA2B lead spacing is not specified. S103M69Z5UP63K7R has 0.295" (7.50mm) lead spacing with formed leads - kinked configuration. Physical board layout must accommodate this spacing.

Q: Why is the substitute part larger?

A: The S103M69Z5UP63K7R achieves equivalent electrical performance with different internal construction and dielectric material (Z5U vs. F). Physical size increase is inherent to the substitute design and manufacturing process.

Q: Is the substitute part currently available?

A: Yes. S103M69Z5UP63K7R is in active production status with 6560 pcs in current inventory, ensuring reliable procurement compared to the obsolete original part.
