Equivalent & Substitute Parts for 61V102MCECT

Part Overview

The KYOCERA AVX 61V102MCECT is a 1000 pF ceramic capacitor rated for 400VAC with X1, Y1 safety ratings, designed for through-hole radial mounting in safety-critical applications. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. Substitute parts must maintain identical electrical specifications (capacitance, voltage rating, tolerance) and safety certifications while accommodating available alternatives from active manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance: Must be 1000 pF (no tolerance variation)
Voltage Rating: Must be 400VAC minimum
Safety Ratings: Must include X1 and Y1 certifications
Tolerance: ±20% or tighter (±10% acceptable)
Mounting: Through-hole radial configuration required
Lead Spacing: 0.394" (10.00mm) standard
Operating Temperature Range: -40°C ~ 125°C minimum

All KEMET substitute parts listed maintain these core electrical and mechanical parameters. Variations in temperature coefficient (Y5V, Y5U, Y5P) and physical diameter do not affect functional substitutability for this application, as these parameters remain within acceptable ranges for safety-rated capacitor applications.

Engineering Selection Recommendations

All listed KEMET substitutes are active products with ROHS3 compliance and REACH unaffected status, providing long-term availability and regulatory compliance advantages over the obsolete 61V102MCECT. Selection between substitute options depends on physical space constraints and lead form requirements:

For direct form-factor compatibility (0.315" diameter matching original): Select from C911U102 series (Y5U temperature coefficient) with either 20° or 45° lead angles. These parts maintain identical physical dimensions to the original while providing active product status.

For compact PCB layouts (smaller 0.276" diameter): Select from C901U102 series (Y5V temperature coefficient). These parts reduce board space while maintaining all electrical and safety specifications.

For tighter tolerance requirements (±10% vs ±20%): Select from C941U102 series (Y5P temperature coefficient) with 0.433" diameter. These parts provide improved capacitance tolerance at the cost of increased physical size.

All substitutes maintain X1, Y1 safety ratings, 400VAC voltage specification, and -40°C ~ 125°C operating temperature range required for safety-critical applications.

Frequently Asked Questions (FAQ)

Q: Can C901U102 series parts (0.276" diameter) replace the original 61V102MCECT (0.315" diameter)?

A: Yes. The smaller diameter does not affect electrical performance or safety certification. Substitution is valid provided PCB layout accommodates the reduced physical size. Lead spacing remains 0.394" (10.00mm) on all parts.

Q: What is the difference between Y5V, Y5U, and Y5P temperature coefficients?

A: These designations specify capacitance variation over temperature. All three coefficients are acceptable for this application and do not affect substitutability. Selection depends on circuit requirements and available inventory.

Q: Are the 20° and 45° lead angle variants (AAWL20 vs AAWL45) electrically equivalent?

A: Yes. Lead angle affects only physical orientation during insertion. Electrical specifications and safety ratings are identical between variants.

Q: Do KEMET substitutes maintain the same safety certifications as the original KYOCERA AVX part?

A: Yes. All KEMET substitutes carry X1, Y1 safety ratings identical to the original part, with ROHS3 compliance and REACH unaffected status.

Q: Can C941U102 parts with ±10% tolerance be used in place of ±20% tolerance specifications?

A: Yes. Tighter tolerance (±10%) is a superior specification and provides improved capacitance accuracy. No circuit redesign is required.

Q: What is the impact of selecting a substitute with different physical diameter?

A: Physical diameter affects only PCB layout and component placement. Electrical performance, voltage rating, capacitance, and safety certifications remain unchanged. Verify PCB footprint clearance before selection.
