Sourcing an EOL Murata Ceramic Capacitor for a US Medical Equipment Manufacturer

Customer Profile

A US-based medical device company specializing in next-generation patient monitoring equipment. Their designs require extremely stable and reliable passive components to meet strict regulatory, safety, and long-lifecycle performance requirements.

The Challenge

The customer needed the CGJ2B2X7R1C102K050BA, a 1000 pF ±10% 16V X7R multilayer ceramic capacitor in 0402 package — a part that went EOL in 2022.

They faced several obstacles:

• No active production or authorized stock remaining

• Demand concentrated in medical and aerospace applications

• Open-market availability: extremely limited and inconsistent

• High risk of counterfeit or reclaimed passives due to small footprint components

• Redesigning the board would trigger requalification and FDA validation overhead

For medical devices, even a simple 0402 capacitor cannot be substituted without extensive reliability testing and compliance checks, delays were not an option.

The Product

Murata CGJ2B2X7R1C102K050BA

• 1000 pF, ±10% tolerance

• 16V rating

• X7R dielectric for stable temperature performance

• 0402 (1005 metric) compact footprint

• Commonly used in filtering, timing, and power stability circuits in medical electronics

Maketronics’ Solution

Leveraging its vetted obsolete component network, Maketronics sourced:

• New, unused, original Murata stock

• Perfect condition with no signs of prior use or soldering

• Stored correctly to prevent microcracks or moisture exposure

• Traceable packaging and supplier documentation

To ensure absolute reliability, Maketronics arranged for the components to be tested at a certified independent laboratory, following industry best practices for passive components

Every piece passed, confirming they would perform flawlessly in the customer's regulated medical application.

The Outcome

• Customer received high-integrity, authenticated Murata stock

• No redesign, requalification, or certification delays

• Production continuity secured for a medically critical device

• Supply chain gap resolved despite global scarcity of the part

Key Takeaway

Even with small-form-factor passives, where authenticity and reliability are hardest to guarantee. Maketronics delivers genuine, fully tested, EOL components to keep medical devices compliant, safe, and on schedule.

When your application cannot fail, Maketronics ensures your components won’t either.
