Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Specifications):

The KYOCERA AVX SR152A8R2DAA and SR152A8R2DAR are direct electrical equivalents to the M15G829D2-F. Both parts maintain the 8.2 pF capacitance, ±0.5pF tolerance, 200V rating, C0G/NP0 temperature coefficient, and -55°C to 125°C operating range. These parts are classified as Active products with ROHS3 compliance. The SR152 series offers a compact form factor with reduced height (0.150" seated height versus 0.270" for the original part), making them suitable for space-constrained applications while maintaining the required 0.100" lead spacing for standard PCB layouts.

Upgrade Substitutes (Enhanced Specifications):

KEMET GoldMax 300 Comm C0G series parts (C315C and C320C variants) provide enhanced voltage ratings of 250V with equivalent or tighter tolerance specifications. The C315C829D2G5TA maintains the original 200V rating with ±0.5pF tolerance and Active product status. The C315C829BAG5TA, C315C829CAG5TA, and C315C829DAG5TA offer 250V ratings with tolerance options of ±0.1pF, ±0.25pF, and ±0.5pF respectively. The C320C series variants provide identical electrical specifications with larger physical dimensions (0.200" L x 0.125" W versus 0.150" L x 0.100" W). All KEMET substitutes feature Low ESL characteristics and maintain the 0.100" lead spacing requirement.

Product Status Consideration:

All substitute parts listed are classified as Active products with current manufacturing support, eliminating obsolescence risk associated with the original M15G829D2-F component. Selection between direct and upgrade substitutes depends on circuit voltage margin requirements and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can SR152A8R2DAA and SR152A8R2DAR be used interchangeably with M15G829D2-F?

A: Yes. Both KYOCERA AVX parts are direct electrical equivalents with identical capacitance (8.2 pF), tolerance (±0.5pF), voltage rating (200V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). The 0.100" lead spacing is compatible with standard PCB layouts designed for the original part. Physical dimensions differ slightly, with the SR152 series offering a more compact profile.

Q: What is the difference between C315C and C320C KEMET substitutes?

A: The C315C and C320C series differ in physical dimensions. The C315C measures 0.150" L x 0.100" W with a maximum seated height of 0.183", while the C320C measures 0.200" L x 0.125" W with a maximum seated height of 0.290". Both maintain the 0.100" lead spacing and identical electrical specifications. Selection depends on available PCB space and layout constraints.

Q: Can I use a 250V rated substitute in a 200V circuit?

A: Yes. A higher voltage rating provides additional safety margin and is electrically compatible with circuits designed for 200V operation. KEMET C315C and C320C variants rated at 250V are suitable for applications originally specified for 200V, provided physical dimensions accommodate the PCB layout.

Q: What tolerance options are available among the substitutes?

A: Tolerance options range from ±0.1pF (tightest) to ±0.5pF (equivalent to original). KYOCERA AVX SR152 series maintains ±0.5pF. KEMET C315C and C320C series offer ±0.1pF (BAG5TA variants), ±0.25pF (CAG5TA variants), and ±0.5pF (DAG5TA and D2G5TA variants). Tighter tolerances provide improved frequency stability in precision applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the regulatory status of the original M15G829D2-F component.

Q: What is the significance of the SR122A8R2DAR part listed as a similar substitute?

A: The SR122A8R2DAR maintains identical electrical specifications (8.2 pF, ±0.5pF, 200V, C0G/NP0) but differs in lead spacing (0.200" versus 0.100") and physical dimensions. This part is suitable only for applications where the larger 0.200" lead spacing is compatible with the PCB layout. It is not a direct substitute for standard 0.100" lead spacing designs.

Q: How do I determine which substitute is best for my application?

A: Evaluate based on three criteria: (1) PCB lead spacing requirement (0.100" or 0.200"), (2) available physical space for component height and width, and (3) voltage margin requirements. For direct replacement with minimal design changes, select SR152A8R2DAR. For enhanced voltage margin in compact form factors, select C315C variants. For larger PCB layouts with enhanced specifications, select C320C variants.
