1206J2002P70DCT Equivalent & Substitute Parts

Part Overview

The 1206J2002P70DCT is a 2.7 pF ceramic capacitor manufactured by Knowles Syfer, rated for 200V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope.

Substitute Part Grouping Explanation

Substitution eligibility for the 1206J2002P70DCT is determined by the following critical parameters:

• Capacitance value: 2.7 pF (exact match required)
• Voltage rating: 200V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: C0G/NP0 (mandatory for stability requirements)
• Package footprint: 1206 (3216 Metric) (physical compatibility requirement)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)
• Moisture sensitivity: MSL 1 (unlimited shelf life requirement)
• Compliance: ROHS3 and REACH Unaffected status

The substitute part KGM31BCG2D2R7CT from KYOCERA AVX meets all substitution criteria while offering improved tolerance specification (±0.25pF versus ±0.5pF) and reduced physical thickness.

Parameter Comparison

Engineering Selection Recommendations

Both the 1206J2002P70DCT and KGM31BCG2D2R7CT are active production parts with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). The KGM31BCG2D2R7CT substitute offers tighter capacitance tolerance (±0.25pF) and reduced thickness (0.037" versus 0.063"), which may provide advantages in space-constrained applications. Selection between these parts should be based on design requirements for tolerance specification and available board height clearance. Both parts maintain equivalent electrical performance across the specified operating temperature range and voltage rating.

Frequently Asked Questions (FAQ)

Q: Can KGM31BCG2D2R7CT be used as a direct replacement for 1206J2002P70DCT?

A: Yes. Both parts share identical capacitance (2.7 pF), voltage rating (200V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package footprint (1206/3216 Metric), and compliance status. The substitute offers improved tolerance and reduced thickness.

Q: What is the significance of the tolerance difference (±0.5pF versus ±0.25pF)?

A: Tolerance defines the acceptable deviation from the nominal 2.7 pF value. The KGM31BCG2D2R7CT provides tighter tolerance, resulting in more precise capacitance values. Applications requiring strict capacitance accuracy benefit from the ±0.25pF specification.

Q: Are there physical compatibility concerns with the reduced thickness of KGM31BCG2D2R7CT?

A: No. The reduced thickness (0.037" versus 0.063") is a dimensional improvement that provides greater board clearance. The 1206 package footprint and mounting type remain identical, ensuring mechanical compatibility with existing PCB designs.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture sensitivity concerns. Standard surface-mount component handling procedures apply to both parts.

Q: Are there supply or availability differences between these parts?

A: Inventory levels differ. The 1206J2002P70DCT has 678 pieces in stock, while KGM31BCG2D2R7CT has 1066 pieces available. Availability should be confirmed with the supplier for specific project timelines.
