Equivalent & Substitute Parts for 5SR103MBJAE

Part Overview

The 5SR103MBJAE is a 10000 pF ceramic capacitor rated at 1000V with Y5U temperature coefficient, manufactured by KYOCERA AVX. This radial disc capacitor is designed for general-purpose applications requiring high voltage performance. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitution for the 5SR103MBJAE is based on the following critical parameters that must remain constant:

Capacitance value: 10000 pF
Tolerance: ±20%
Voltage rating: 1000V (1kV)
Mounting type: Through Hole
Package type: Radial, Disc
Lead style: Straight

The substitute parts listed are Vishay Beyschlag/Draloric/BC Components S-series ceramic capacitors that maintain these core electrical and mechanical specifications. While the temperature coefficient differs from Y5U to Z5U, and the operating temperature range extends to 125°C (versus 85°C for the original), these substitutes provide equivalent or superior performance for the specified capacitance, voltage, and tolerance requirements. The primary variation among substitutes is lead spacing, which affects PCB layout compatibility.

Engineering Selection Recommendations

All listed Vishay Beyschlag/Draloric/BC Components substitutes maintain the critical electrical specifications: 10000 pF capacitance, ±20% tolerance, and 1000V voltage rating. All substitute parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment.

The primary selection criterion is lead spacing compatibility with existing PCB layouts. For direct footprint compatibility with the original 5SR103MBJAE (0.295" lead spacing), select S103M47Z5UN63K7R or S103M47Z5UN6BJ7R. For applications requiring alternative lead spacing, the full range of options accommodates 5.00mm, 6.40mm, 7.50mm, and 10.00mm pitch requirements.

Physical dimensions differ from the original part. The substitute parts have reduced diameter (0.472" versus 0.512") but increased height (0.661" versus 0.236"). Verify PCB clearance and component placement constraints before final selection.

Frequently Asked Questions (FAQ)

Q: Can S103M47Z5UN63K7R directly replace 5SR103MBJAE in existing designs?

A: S103M47Z5UN63K7R matches the critical electrical specifications and lead spacing (0.295" / 7.50mm) of the original part. However, the increased height (0.661" versus 0.236") requires verification of available vertical clearance on the PCB assembly.

Q: What is the difference between Y5U and Z5U temperature coefficients?

A: Both are Class II ceramic dielectric materials with ±20% capacitance tolerance. Y5U operates from -30°C to 85°C, while Z5U extends to -30°C to 125°C. Z5U provides a wider operating range suitable for higher temperature environments.

Q: Which substitute part offers the closest physical footprint match?

A: S103M47Z5UN63K7R and S103M47Z5UN6BJ7R both provide 0.295" (7.50mm) lead spacing matching the original part. S103M47Z5UN63K7R has the highest inventory availability (12,551 pcs).

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed Vishay Beyschlag/Draloric/BC Components substitutes are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What lead spacing options are available among the substitutes?

A: Five lead spacing configurations are available: 0.197" (5.00mm), 0.252" (6.40mm), 0.295" (7.50mm), and 0.394" (10.00mm). Select based on PCB hole pattern requirements.
