Substitute Part Grouping Explanation

Substitution eligibility for the 1206Y1000331FCT is determined by strict alignment of the following parameters:

• Capacitance value: 330 pF (exact match required)
• Tolerance: ±1% (exact match required)
• Voltage rating: 100V (exact match or higher acceptable)
• Temperature coefficient: C0G or NP0 (equivalent designations)
• Operating temperature range: -55°C to 125°C (exact match or wider range acceptable)
• Package: 1206 (3216 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

The identified substitute part KGM31BCG2A331FT from KYOCERA AVX meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 1206Y1000331FCT and KGM31BCG2A331FT are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability, lead time, and supply chain requirements. The KGM31BCG2A331FT from KYOCERA AVX currently has higher inventory availability (4663 units) compared to the Knowles Syfer part (922 units). Both components carry identical electrical specifications, mechanical dimensions, and regulatory certifications, making them functionally interchangeable in circuit applications. The thickness specification differs slightly (1.60mm maximum for the main part versus 0.94mm maximum for the substitute), with the substitute offering a thinner profile that may provide layout advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can KGM31BCG2A331FT be used as a direct replacement for 1206Y1000331FCT?

A: Yes. Both parts share identical capacitance (330 pF), tolerance (±1%), voltage rating (100V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), package dimensions (1206/3216 Metric), and compliance certifications (ROHS3, REACH unaffected). They are functionally equivalent for circuit applications.

Q: Are there any dimensional differences between these parts?

A: Both parts have identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). The maximum thickness differs: the 1206Y1000331FCT specifies 0.063" (1.60mm) while the KGM31BCG2A331FT specifies 0.037" (0.94mm). The thinner profile of the substitute may provide layout flexibility in height-constrained applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS code (8532.24.0020) classifications.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts have Moisture Sensitivity Level 1 (MSL 1), indicating unlimited shelf life without moisture control requirements.

Q: Are there supply chain considerations for selecting between these parts?

A: The KGM31BCG2A331FT currently has significantly higher inventory availability (4663 units) compared to the 1206Y1000331FCT (922 units), which may influence lead time and procurement decisions.
