Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR325E105MAT is determined by the following criteria:

Primary Electrical Match Requirements:

• Capacitance: 1 µF
• Tolerance: ±20%
• Voltage Rating: 50V (minimum)
• Temperature Coefficient: Z5U
• Operating Temperature: 10°C ~ 85°C

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.200" (5.08mm)
• Lead Style: Formed Leads - Kinked or Straight (both acceptable)

Direct Substitutes maintain identical electrical specifications and compatible mechanical dimensions. These parts are interchangeable in applications designed for SR325E105MAT.

Upgrade Substitutes provide higher voltage ratings (100V) while maintaining all other electrical parameters. These parts are suitable for applications where increased voltage margin is acceptable or beneficial.

Cross-Manufacturer Substitutes from KEMET (C330C105M5U5TA series) match all electrical specifications and mechanical requirements, offering alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (50V Rating): SR215E105MAA, SR215E105MAR, SR215E105MARTR1, SR305E105MAR, SR305E105MARTR1, C330C105M5U5TA, and C330C105M5U5TA7301 are direct electrical equivalents to SR325E105MAT. All maintain 1 µF capacitance, ±20% tolerance, 50V rating, Z5U temperature coefficient, and 10°C ~ 85°C operating range. Selection among these parts depends on packaging format (Bulk vs. Cut Tape) and mechanical fit within the PCB layout. SR305E105MARTR1 provides the closest dimensional match to the original part with identical lead spacing and compatible height specifications.

Upgrade Substitutes (100V Rating): SR301E105MAR and SR651E105MAATR1 provide increased voltage rating (100V) while maintaining all other electrical parameters. These parts are suitable for applications where higher voltage margin is required or where circuit redesign permits voltage rating increase. Both parts maintain ROHS3 compliance and identical operating temperature range.

Cross-Manufacturer Option: C330C105M5U5TA and C330C105M5U5TA7301 (KEMET GoldMax 300 Comm Z5U series) are functionally equivalent to SR325E105MAT with matching electrical specifications. Dimensional variations are minor and within acceptable tolerance for standard through-hole PCB applications. Both variants are ROHS3 compliant.

All listed parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can SR215E105MAA replace SR325E105MAT directly? A: SR215E105MAA matches all electrical specifications (1 µF, ±20%, 50V, Z5U) and lead spacing (0.200"). However, it has smaller overall dimensions (0.200" L x 0.125" W vs. 0.300" L x 0.150" W). Verify PCB layout accommodates the smaller footprint before substitution.

Q: What is the difference between SR305E105MAR and SR305E105MARTR1? A: Both parts are electrically identical with matching dimensions and lead spacing. The primary difference is packaging: SR305E105MAR is supplied in Bulk format, while SR305E105MARTR1 is supplied in Cut Tape (CT) format. Lead style differs slightly (Straight vs. Straight), but both are compatible with standard through-hole assembly.

Q: Can I use SR301E105MAR (100V) instead of SR325E105MAT (50V)? A: Yes. SR301E105MAR maintains identical capacitance (1 µF), tolerance (±20%), temperature coefficient (Z5U), and operating range (10°C ~ 85°C). The higher voltage rating (100V vs. 50V) provides additional safety margin and is suitable for applications where circuit voltage does not exceed 50V. Verify PCB layout accommodates the 0.300" L x 0.125" W dimensions.

Q: Are KEMET C330C105M5U5TA parts compatible with KYOCERA AVX SR325E105MAT? A: Yes. C330C105M5U5TA and C330C105M5U5TA7301 match all electrical specifications and lead spacing (0.200"). Dimensional differences are minor (0.280" L x 0.160" W vs. 0.300" L x 0.150" W). Both are ROHS3 compliant and suitable for general-purpose applications requiring 1 µF, 50V, Z5U ceramic capacitors.

Q: What does the "TR1" suffix in part numbers like SR215E105MARTR1 indicate? A: The "TR1" suffix indicates Cut Tape (CT) packaging format, typically used for automated assembly processes. Parts without this suffix are supplied in Bulk format. Electrical and mechanical specifications remain identical between TR1 and non-TR1 variants.

Q: Can I substitute parts with different lead styles (Formed Leads - Kinked vs. Straight)? A: Both lead styles are compatible with standard through-hole PCB assembly. Formed Leads - Kinked provide slight mechanical retention during insertion, while Straight leads offer standard through-hole compatibility. Selection depends on assembly equipment and PCB design preferences. Both styles maintain identical electrical performance and lead spacing (0.200").
