0603J2000910GUT Equivalent & Substitute Parts

Part Overview

The 0603J2000910GUT is a 91 pF ceramic capacitor manufactured by Knowles Syfer, designed for RF and microwave applications requiring high Q, low loss, and ultra-low ESR characteristics. This surface mount MLCC operates across -55°C to 125°C with a rated voltage of 200V and C0G/NP0 temperature coefficient stability. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to address inventory availability, extended voltage ratings, or improved tolerance specifications while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0603J2000910GUT is determined by the following mandatory parameters:

• Capacitance Value: Must be 91 pF (no tolerance variation)
• Temperature Coefficient: Must be C0G or NP0 (interchangeable designations for the same characteristic)
• Package / Case: Must be 0603 (1608 Metric) for PCB footprint compatibility
• Mounting Type: Must be Surface Mount MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• RoHS Compliance: Must maintain ROHS3 status

The substitute part CBR06C910FAGAC meets all mandatory substitution criteria. Variations in voltage rating (250V vs. 200V), tolerance (±1% vs. ±2%), and thickness (0.90mm vs. 0.80mm) are within acceptable engineering parameters for this application category and do not prevent substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the 0603J2000910GUT and CBR06C910FAGAC are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings, making either suitable for RF and microwave applications. The CBR06C910FAGAC offers a higher voltage rating (250V vs. 200V) and tighter tolerance (±1% vs. ±2%), providing enhanced performance margins in high-frequency circuits. The 0.10mm thickness difference (0.90mm vs. 0.80mm) is within standard PCB assembly tolerances for 0603 packages. Selection between these parts should be based on circuit voltage requirements, tolerance specifications, and component availability.

Frequently Asked Questions (FAQ)

Q: Can CBR06C910FAGAC replace 0603J2000910GUT in existing designs?

A: Yes. Both parts share identical capacitance (91 pF), temperature coefficient (C0G/NP0), package footprint (0603), and operating temperature range (-55°C ~ 125°C). The higher voltage rating and tighter tolerance of the KEMET part are compatible with applications designed for the Knowles Syfer part.

Q: What is the significance of the voltage rating difference (200V vs. 250V)?

A: The CBR06C910FAGAC operates at a higher maximum voltage (250V) compared to the 0603J2000910GUT (200V). This provides additional voltage margin in circuits operating near the 200V threshold. Circuits designed for 200V operation remain fully compatible with the 250V-rated substitute.

Q: Does the thickness difference (0.80mm vs. 0.90mm) affect PCB assembly?

A: The 0.10mm thickness difference falls within standard manufacturing tolerances for 0603 MLCC packages and does not require PCB layout modifications. Both parts use identical length and width dimensions (1.60mm x 0.80mm).

Q: Are both parts suitable for RF and microwave applications?

A: Yes. Both the 0603J2000910GUT and CBR06C910FAGAC feature high Q, low loss, and ultra-low ESR characteristics specified for RF and microwave frequency applications.

Q: What packaging formats are available for the substitute part?

A: The CBR06C910FAGAC is supplied in Tape & Reel (TR) format, standard for automated PCB assembly processes.
