Substitute Part Grouping Explanation

Substitution eligibility for the C327C681KAG5TA is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 680 pF
• Voltage Rating: 250V
• Temperature Coefficient: C0G/NP0
• Mounting Type: Through Hole Radial
• Lead Spacing: 0.200" (5.08mm)
• Operating Temperature Range: -55°C to 125°C

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (lower tolerance value indicates improved precision)
• Physical Height: Minor variations acceptable if within standard radial package envelope
• Inventory Availability: Does not affect electrical compatibility

The substitute part C325C681JAG5TA meets all critical parameters and offers improved tolerance specification (±5% versus ±10%), making it functionally equivalent with enhanced precision capability.

Parameter Comparison

Engineering Selection Recommendations

C327C681KAG5TA Selection Criteria:

• Applications where ±10% tolerance specification is acceptable
• Standard general-purpose ceramic capacitor requirements
• Cost-optimized designs where tighter tolerance is not required
• Current inventory availability of 909 units supports immediate procurement

C325C681JAG5TA Selection Criteria:

• Applications requiring improved capacitance precision with ±5% tolerance
• Designs where tighter tolerance reduces circuit performance variation
• Higher inventory availability (2849 units) supports larger production runs
• Slightly reduced seated height (0.300" vs 0.320") may benefit space-constrained layouts

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Both maintain active production status within the GoldMax 300 Comm C0G series. Selection between these parts depends on tolerance requirements and inventory availability rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can C325C681JAG5TA replace C327C681KAG5TA in existing designs?

A: Yes. Both parts share identical capacitance (680 pF), voltage rating (250V), temperature coefficient (C0G/NP0), mounting type (through-hole radial), and lead spacing (0.200"). The substitute offers tighter tolerance (±5% vs ±10%) and is electrically and mechanically compatible. The 0.02" difference in seated height does not affect standard PCB layouts.

Q: What is the difference between ±10% and ±5% tolerance?

A: Tolerance specifies the allowable deviation from the nominal 680 pF capacitance value. C327C681KAG5TA allows deviation between 612 pF and 748 pF. C325C681JAG5TA allows deviation between 646 pF and 714 pF. Tighter tolerance (±5%) provides more predictable circuit performance in applications sensitive to capacitance variation.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.200" / 5.08mm) and radial package configuration. The substitute part is 0.02" shorter in seated height, which does not affect standard through-hole PCB designs.

Q: What does C0G/NP0 temperature coefficient mean?

A: C0G and NP0 are equivalent designations for temperature coefficient indicating negligible capacitance change across the operating temperature range (-55°C to 125°C). Both parts maintain stable capacitance performance across this range.

Q: Are both parts RoHS compliant?

A: Yes. Both C327C681KAG5TA and C325C681JAG5TA are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications where ±5% tolerance provides measurable benefit, C325C681JAG5TA is preferred. For general-purpose applications where ±10% tolerance is acceptable, either part is suitable. Inventory availability (2849 units for C325C681JAG5TA vs 909 units for C327C681KAG5TA) may influence procurement decisions for high-volume production.
