Substitute Part Grouping Explanation

Substitution of the 1206J1000100GCT is determined by strict equivalence in the following electrical and mechanical parameters:

• Capacitance value: 10 pF (exact match required)
• Voltage rating: 100V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: C0G/NP0 (mandatory for stability)
• Package format: 1206 (3216 Metric) (physical and footprint compatibility)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)
• Operating temperature range: -55°C to 125°C (functional envelope)
• Compliance standards: ROHS3, REACH Unaffected, EAR99 classification

Tolerance variations (±2% vs. ±1%) are permitted when the substitute part offers equal or tighter tolerance specifications, as this represents an improvement in capacitance accuracy without compromising circuit performance.

Engineering Selection Recommendations

The KGM31BCG2A100FT from KYOCERA AVX is a direct substitute for the 1206J1000100GCT. Both parts meet identical electrical specifications for capacitance, voltage rating, and temperature coefficient. The substitute part offers improved tolerance performance (±1% vs. ±2%), which provides enhanced capacitance accuracy without introducing any compatibility concerns.

Both parts maintain full compliance with ROHS3 and REACH regulations, carry identical moisture sensitivity ratings (MSL 1), and share the same ECCN classification (EAR99). Physical dimensions and package footprints are equivalent, ensuring seamless integration into existing PCB designs and assembly processes.

Selection between these parts may be based on inventory availability, lead time, cost considerations, or established supplier relationships, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the KGM31BCG2A100FT replace the 1206J1000100GCT in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (10 pF), voltage rating (100V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 1206 package format. The substitute part offers tighter tolerance (±1%), which is an improvement over the original specification (±2%).

Q: Are there physical dimension differences between these parts?

A: Both parts conform to the 1206 (3216 Metric) package standard with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). The substitute part has a maximum thickness of 0.037" (0.94mm) compared to the original specification, which does not affect PCB assembly or circuit performance.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the 1206J1000100GCT and KGM31BCG2A100FT are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements.

Q: What is the primary advantage of the substitute part?

A: The KGM31BCG2A100FT provides tighter capacitance tolerance (±1% vs. ±2%), resulting in improved accuracy and consistency in circuit performance. This represents a specification upgrade with no trade-offs in electrical or mechanical compatibility.

Q: Are there any application limitations when using the substitute part?

A: No. The substitute part is rated for the same general purpose applications and maintains identical operating temperature range and voltage specifications. It is suitable for all applications where the original part is specified.
