Key Parameters

Substitute Part Grouping Explanation

Substitution of the C1608JB1C225K080AB is determined by strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following parameters:

• Capacitance: 2.2 µF ±10%
• Package / Case: 0603 (1608 Metric)
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Voltage rating may be equal or higher than the original 16V specification. Temperature coefficient may differ (JB, X5R, X6S, X7S) provided the operating temperature range meets or exceeds the original -25°C to 85°C requirement. All substitute parts are manufactured by TDK Corporation and maintain identical physical dimensions and electrical tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of C1608JB1C225K080AB in existing designs, C1608X5R1C225K080AB is the primary recommendation. This part maintains identical voltage rating (16V) and package specification while offering Active product status, ensuring long-term availability. The X5R temperature coefficient provides extended operating range (-55°C to 85°C) compared to the original JB specification, delivering improved thermal stability without design modification.

C1608X6S1C225K080AC and C1608X7S1C225K080AC provide alternative solutions with higher temperature coefficient ratings (X6S and X7S respectively), suitable for applications requiring extended upper temperature limits to 105°C and 125°C. Both maintain 16V rating and Active status.

For applications permitting voltage derating, C1608X5R1E225K080AB (25V) and C1608X5R1V225K080AC (35V) offer higher voltage margins with Active product status and extended temperature range. These parts are suitable when circuit design allows for higher voltage-rated components.

C1608JB1V225K080AC provides voltage upgrade (35V) while maintaining JB temperature coefficient, though this part retains Last Time Buy status and should not be selected for new designs requiring long-term supply assurance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical physical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm).

Frequently Asked Questions (FAQ)

Q: Can C1608X5R1C225K080AB replace C1608JB1C225K080AB directly?

A: Yes. Both parts share identical capacitance (2.2 µF), tolerance (±10%), voltage rating (16V), package (0603), and physical dimensions. The X5R temperature coefficient provides extended operating range (-55°C to 85°C versus -25°C to 85°C), making it a direct functional replacement. C1608X5R1C225K080AB is Active status, ensuring supply continuity.

Q: What is the difference between JB, X5R, X6S, and X7S temperature coefficients?

A: Temperature coefficient designates the capacitance change across the operating temperature range. JB provides ±10% capacitance change over -25°C to 85°C. X5R provides ±15% change over -55°C to 85°C. X6S provides ±15% change over -55°C to 105°C. X7S provides ±15% change over -55°C to 125°C. Selection depends on application temperature requirements and acceptable capacitance variation.

Q: Can I use a 35V rated capacitor in place of a 16V rated capacitor?

A: Yes, provided circuit design permits. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. C1608JB1V225K080AC (35V) and C1608X5R1V225K080AC (35V) are valid substitutes. Verify that board layout and component placement accommodate any dimensional variations, though all listed parts maintain identical 0603 package dimensions.

Q: Why is C1608JB1C225K080AB marked Last Time Buy?

A: Last Time Buy status indicates TDK Corporation has discontinued production. Existing inventory is available but will not be replenished. For new designs or long-term production requirements, selection of Active status parts (C1608X5R1C225K080AB, C1608X5R1E225K080AB, C1608X5R1V225K080AC, C1608X6S1C225K080AC, C1608X7S1C225K080AC) is required to ensure supply chain continuity.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specification.

Q: What packaging options are available?

A: C1608JB1C225K080AB is supplied in Tape & Reel (TR). Substitute parts are available in Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats. Verify packaging compatibility with procurement and assembly processes before selection.
