Substitute Part Grouping Explanation

Substitution for the 08055C102JAT2P is determined by the following critical parameters: capacitance value (1000 pF), package type (0805), mounting method (surface mount MLCC), and operating temperature range (-55°C ~ 125°C). All substitute parts must maintain these core specifications.

Substitute parts are grouped into three categories:

Category 1: KYOCERA AVX Upgrades with Improved Temperature Coefficient (C0G/NP0) Parts KGM21BCG1H102FT and KGM21BCG1H102GT offer superior temperature stability with C0G/NP0 coefficient at 50V rating. These maintain identical capacitance, voltage, package, and temperature range while providing tighter tolerance (±1% and ±2% respectively).

Category 2: KYOCERA AVX Upgrades with Higher Voltage Rating (50V to 100V/200V) Parts KGM21BCG2A102FT, KGM21BCG2A102GT, KGM21NR72A102JT, and KGM21NR72D102JT maintain X7R temperature coefficient with increased voltage ratings (100V or 200V). These are direct upgrades for applications requiring higher voltage margin while preserving all other electrical characteristics.

Category 3: KYOCERA AVX Direct Equivalents (X7R, 50V) Parts KGM21NR71H102JM and KGM21NR71H102JT are functionally identical to the main part with identical electrical specifications and X7R coefficient. These represent active production alternatives from the same manufacturer.

Category 4: Cross-Manufacturer Direct Equivalents Parts 0805B102J500CT (Walsin Technology Corporation) and C0805C102J5RAC7800 (KEMET) provide direct electrical equivalence with identical 1000 pF, ±5%, 50V, X7R specifications in 0805 package. These enable multi-source procurement strategies.

Engineering Selection Recommendations

For direct replacement of the discontinued 08055C102JAT2P, select from active production parts with identical electrical specifications: KGM21NR71H102JT (KYOCERA AVX, 98086 Pcs available) or C0805C102J5RAC7800 (KEMET, 118147 Pcs available). Both maintain 1000 pF capacitance, ±5% tolerance, 50V rating, X7R temperature coefficient, and 0805 package with full ROHS3 compliance and MSL 1 rating.

For applications requiring improved temperature stability, KGM21BCG1H102FT or KGM21BCG1H102GT provide C0G/NP0 temperature coefficient with tighter tolerance (±1% or ±2%) at 50V, maintaining identical package and compliance ratings with superior long-term stability.

For circuits with higher voltage headroom requirements, KGM21NR72A102JT (100V) or KGM21NR72D102JT (200V) offer voltage upgrades while preserving X7R characteristics and 0805 package. These are suitable for designs where the original 50V rating presents insufficient margin.

All recommended substitutes are ROHS3 compliant, MSL 1 rated, and rated for -55°C ~ 125°C operating temperature, ensuring compatibility with the original part's environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can KGM21NR71H102JT be used as a direct replacement for 08055C102JAT2P? A: Yes. Both parts share identical electrical specifications: 1000 pF capacitance, ±5% tolerance, 50V voltage rating, X7R temperature coefficient, and 0805 package. KGM21NR71H102JT is an active production part with significantly higher inventory availability (98086 Pcs).

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% change across the same range. C0G/NP0 parts (KGM21BCG1H102FT, KGM21BCG1H102GT) are suitable for precision applications requiring minimal capacitance drift.

Q: Are higher voltage rated parts (100V, 200V) compatible with 50V circuits? A: Yes. Higher voltage rated parts operate safely in lower voltage applications. KGM21NR72A102JT (100V) and KGM21NR72D102JT (200V) maintain identical capacitance and tolerance while providing additional voltage margin. Physical dimensions remain compatible with 0805 package footprints.

Q: Can cross-manufacturer parts (Walsin, KEMET) be substituted for KYOCERA AVX? A: Yes. 0805B102J500CT (Walsin) and C0805C102J5RAC7800 (KEMET) provide electrical equivalence with identical 1000 pF, ±5%, 50V, X7R specifications. Both are ROHS3 compliant and MSL 1 rated. Cross-manufacturer substitution enables multi-source procurement and supply chain flexibility.

Q: What packaging format is available for these parts? A: All substitute parts are supplied in Tape & Reel (TR) format for automated assembly. The 0805 (2012 Metric) package dimensions are 0.079" L × 0.049" W (2.01mm × 1.25mm) with thickness ranging from 0.035" to 0.039" depending on manufacturer and dielectric material.

Q: Are all substitute parts RoHS and REACH compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status. ECCN classification is EAR99 for all parts, and HTSUS code is 8532.24.0020.
