5SR103MBJLA Equivalent & Substitute Parts
Part Overview
The 5SR103MBJLA is a 10000 pF ceramic capacitor rated at 1000V (1kV) with Y5U temperature coefficient, manufactured by KYOCERA AVX. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part is designed for general-purpose applications requiring high-voltage ceramic capacitance in a radial, disc configuration with through-hole mounting.

Substitute Part Grouping Explanation
Substitute parts for the 5SR103MBJLA are selected based on strict electrical and mechanical compatibility criteria. All substitute parts maintain the core electrical specifications: 10000 pF capacitance, ±20% tolerance, and 1000V voltage rating. The primary substitutes are manufactured by Vishay Beyschlag/Draloric/BC Components under the S-series designation.
The substitution logic is based on the following allowed parameters:
- Capacitance value (10000 pF)
- Voltage rating (1000V minimum)
- Tolerance (±20%)
- Mounting type (Through Hole)
- Package configuration (Radial, Disc)
- Temperature coefficient compatibility (Y5U to Z5U transition)
- Lead spacing variations (5.00mm to 10.00mm)
- Physical dimensions (0.472" Dia, 0.661" Height)
Temperature coefficient differs between the main part (Y5U) and substitutes (Z5U), with Z5U providing an extended operating temperature range of -30°C ~ 125°C compared to the original -30°C ~ 85°C specification.

Engineering Selection Recommendations
All listed substitute parts are active production components manufactured by Vishay Beyschlag/Draloric/BC Components and carry ROHS3 compliance certification. The original 5SR103MBJLA is obsolete, making these substitutes the appropriate selection for new designs and ongoing procurement.
Substitute selection should be based on lead spacing requirements for PCB layout compatibility. The available lead spacing options range from 0.197" (5.00mm) to 0.394" (10.00mm), with the most common spacing at 0.295" (7.50mm) represented by S103M47Z5UN63K7R and S103M47Z5UN64J7R.
All substitutes maintain electrical equivalence at the specified 10000 pF capacitance, ±20% tolerance, and 1000V voltage rating. The temperature coefficient change from Y5U to Z5U provides an extended operating range, which is beneficial for applications requiring operation above 85°C up to 125°C.
Frequently Asked Questions (FAQ)
Q: Can S-series parts directly replace the 5SR103MBJLA in existing designs?
A: Electrical substitution is direct for the specified capacitance, voltage, and tolerance values. Physical layout compatibility depends on lead spacing. The original part uses 0.295" (7.50mm) lead spacing; substitute parts with matching lead spacing (S103M47Z5UN63K7R, S103M47Z5UN64J7R, S103M47Z5UN6BJ7R) provide direct PCB compatibility without layout modification.
Q: What is the difference between Y5U and Z5U temperature coefficients?
A: Y5U (original) specifies -30°C ~ 85°C operating range. Z5U (substitutes) specifies -30°C ~ 125°C operating range. Z5U provides extended high-temperature capability, making it suitable for applications requiring operation above 85°C. Both maintain the same capacitance tolerance and voltage rating.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed Vishay Beyschlag/Draloric/BC Components substitutes carry ROHS3 compliance certification. The original 5SR103MBJLA is marked as REACH Unaffected; all substitutes maintain REACH Unaffected status.
Q: Which substitute part has the closest physical dimensions to the original?
A: The original 5SR103MBJLA measures 0.512" diameter with 0.236" seated height. All substitute parts measure 0.472" diameter with 0.661" seated height, representing a larger physical footprint. PCB layout must accommodate this dimensional change.
Q: What lead spacing options are available for the substitutes?
A: Lead spacing varies across the substitute range: 0.197" (5.00mm), 0.252" (6.40mm), 0.295" (7.50mm), and 0.394" (10.00mm). Selection should match the PCB hole pattern of the original design or be accommodated through layout modification.
