Key Parameters

Substitute Part Grouping Explanation

Substitution of the CL31C681JHHNNNE is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 680 pF
• Tolerance: ±5%
• Voltage rating: 630V
• Temperature coefficient: C0G, NP0

Mechanical Parameters:

• Package format: 1206 (3216 Metric)
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All substitute parts listed maintain identical electrical specifications and package footprint compatibility. Thickness variations among substitute parts remain within acceptable mechanical tolerances for standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CL31C681JHHNNNE (Samsung Electro-Mechanics), C3216C0G2J681J085AA (TDK Corporation), and GRM31B5C2J681JW01L (Murata Electronics)—are functionally equivalent for direct substitution in applications requiring 680 pF, 630V ceramic capacitors with C0G/NP0 temperature stability.

Compliance Alignment: All substitute parts maintain identical RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility across all three manufacturers.

Product Status: All parts carry Active product status, confirming ongoing manufacturing support and supply availability.

Mechanical Compatibility: All parts share identical footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm) and 1206 (3216 Metric) package format, ensuring direct PCB layout compatibility. Thickness variations (1.00mm to 1.80mm) remain within standard assembly process tolerances and do not affect electrical performance or mechanical fit.

Electrical Equivalence: Identical capacitance (680 pF), tolerance (±5%), voltage rating (630V), temperature coefficient (C0G, NP0), and operating temperature range (-55°C ~ 125°C) confirm full electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can C3216C0G2J681J085AA (TDK) be used as a direct replacement for CL31C681JHHNNNE (Samsung)?

A: Yes. Both parts are electrically and mechanically equivalent, with identical capacitance (680 pF), voltage rating (630V), temperature coefficient (C0G, NP0), package format (1206 / 3216 Metric), and compliance certifications (RoHS3, REACH Unaffected, MSL 1).

Q: Are there thickness differences between the substitute parts, and do they affect PCB assembly?

A: Yes, thickness varies: Samsung CL31C681JHHNNNE is 1.80mm, TDK C3216C0G2J681J085AA is 1.00mm, and Murata GRM31B5C2J681JW01L is 1.25mm. These variations remain within standard surface-mount assembly process tolerances and do not affect electrical performance or mechanical fit on standard PCB designs.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related handling restrictions during storage, transport, or assembly.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CL31C681JHHNNNE (Samsung), C3216C0G2J681J085AA (TDK), and GRM31B5C2J681JW01L (Murata) are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -55°C to 125°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across this full temperature range.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. All parts are rated for 630V, making them suitable for high-voltage general-purpose applications within this voltage specification.

Q: Are packaging options different between manufacturers?

A: The main part (CL31C681JHHNNNE) is specified with standard packaging. TDK C3216C0G2J681J085AA and Murata GRM31B5C2J681JW01L are supplied in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly. Packaging format does not affect electrical or mechanical compatibility.
