Engineering Selection Recommendations

KYOCERA AVX Series Substitutes:

SR151E103MAR and SR291E103MARTR2 are direct KYOCERA AVX equivalents with identical electrical specifications. SR151E103MAR features a compact footprint with straight leads and 0.100" lead spacing, suitable for space-constrained layouts. SR291E103MARTR2 offers formed leads with cut tape packaging, providing higher inventory availability (5035 Pcs) and intermediate dimensional profile.

KEMET GoldMax 300 Comm Z5U Series Substitutes:

C315C103M1U5TA, C320C103M1U5TA, C317C103M1U5TA, and C322C103M1U5TA are manufacturer-recommended alternatives from KEMET's GoldMax 300 Comm Z5U series. All meet identical electrical and compliance requirements. Selection depends on lead spacing and physical dimensions:

C315C103M1U5TA and C317C103M1U5TA: Compact 0.150" x 0.100" footprint; C317C103M1U5TA features 0.200" lead spacing for wider pitch applications.
C320C103M1U5TA and C322C103M1U5TA: Larger 0.200" x 0.125" footprint; C322C103M1U5TA features 0.200" lead spacing.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original SR141E103MAT.

Frequently Asked Questions (FAQ)

Q: Can SR151E103MAR replace SR141E103MAT directly on the PCB?

A: SR151E103MAR is electrically equivalent but features a smaller physical footprint (0.150" x 0.100" vs. 0.300" x 0.200") with straight leads instead of kinked formed leads. Lead spacing remains 0.100" (2.54mm), so PCB hole pattern compatibility is maintained. Board layout space availability determines suitability.

Q: What is the difference between 0.100" and 0.200" lead spacing options?

A: Lead spacing refers to the distance between the two radial leads. SR141E103MAT, SR151E103MAR, and SR291E103MARTR2 use 0.100" spacing. C317C103M1U5TA and C322C103M1U5TA use 0.200" spacing. PCB hole patterns must match the selected lead spacing; 0.200" spacing requires wider hole separation and cannot be used in 0.100" spaced footprints.

Q: Are KEMET and KYOCERA AVX parts interchangeable?

A: Yes, within the specified electrical and mechanical parameters. Both manufacturers' parts meet identical capacitance, voltage, temperature coefficient, and compliance requirements. Physical dimensions and lead styles differ, requiring board layout verification before substitution.

Q: What packaging formats are available?

A: SR141E103MAT is supplied in radial packaging. Substitutes are available in Bulk (SR151E103MAR, all KEMET parts) and Cut Tape (SR291E103MARTR2) formats. Packaging selection affects procurement and assembly processes but does not alter electrical performance.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the regulatory status of SR141E103MAT.
