SR325E684MAT Equivalent & Substitute Parts Reference

Part Overview

The SR325E684MAT is a 0.68 µF ceramic capacitor rated at 50V with Z5U temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications and is currently in active production status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, procurement lead times, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR325E684MAT is determined by strict equivalence across the following parameters:

• Electrical Equivalence: Capacitance value (0.68 µF), tolerance (±20%), voltage rating (50V), and temperature coefficient (Z5U) must be identical
• Mechanical Compatibility: Through-hole radial mounting with 0.200" (5.08mm) lead spacing ensures PCB footprint compatibility
• Compliance Alignment: RoHS3 compliance and REACH unaffected status must be maintained
• Operating Conditions: Temperature coefficient Z5U and operating range 10°C ~ 85°C define functional equivalence

The identified substitute parts meet all these criteria and are direct functional equivalents suitable for component selection.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SR325E684MAT, SR305E684MAATR1, and C330C684M5U5TA—are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on the following factors:

SR325E684MAT (Primary): KYOCERA AVX SkyCap® SR series with kinked formed leads and maximum seated height of 0.390" (9.91mm). Suitable for applications where lead style and height clearance are not constrained.

SR305E684MAATR1 (KYOCERA AVX Alternative): Same manufacturer and series as the primary part with straight lead style and reduced maximum seated height of 0.360" (9.14mm). Provides lower profile option while maintaining identical electrical specifications and footprint compatibility.

C330C684M5U5TA (Cross-Manufacturer Alternative): KEMET GoldMax 300 Comm Z5U series with formed leads and 0.360" (9.14mm) maximum seated height. Offers cross-manufacturer sourcing flexibility with slightly different physical dimensions (0.280" L x 0.160" W versus 0.300" L x 0.150" W) while maintaining lead spacing and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can SR305E684MAATR1 replace SR325E684MAT directly on the PCB?

A: Yes. Both parts share identical capacitance (0.68 µF), voltage rating (50V), temperature coefficient (Z5U), lead spacing (0.200"), and radial through-hole mounting. The primary difference is lead style (straight versus kinked) and maximum seated height (0.360" versus 0.390"). Verify PCB clearance requirements before substitution.

Q: Is C330C684M5U5TA electrically equivalent to SR325E684MAT?

A: Yes. The C330C684M5U5TA provides identical electrical specifications: 0.68 µF capacitance, ±20% tolerance, 50V rating, and Z5U temperature coefficient. Physical dimensions differ slightly (0.280" L x 0.160" W versus 0.300" L x 0.150" W), but lead spacing remains 0.200" (5.08mm), ensuring PCB footprint compatibility.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging (SR325E684MAT, C330C684M5U5TA) is supplied in loose quantities suitable for high-volume assembly. Cut tape packaging (SR305E684MAATR1) is supplied on carrier tape and is typically used for automated pick-and-place equipment. Electrical and mechanical specifications are identical; packaging choice depends on assembly process requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. SR325E684MAT, SR305E684MAATR1, and C330C684M5U5TA are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use these parts interchangeably in my design?

A: All three parts meet the same electrical specifications and lead spacing requirements. Verify physical dimensions and lead style compatibility with your PCB layout and assembly process before finalizing component selection.
