Substitute Part Grouping Explanation

Substitution of the 08055A680GAT2P is determined by the following critical parameters:

Electrical Parameters: Capacitance value (68 pF), temperature coefficient (C0G/NP0), and voltage rating must be maintained at minimum. Tolerance may be improved (±1% vs ±2%) without functional impact. Voltage rating may be increased above 50V for enhanced margin.

Mechanical Parameters: Package type (0805/2012 Metric) and mounting type (Surface Mount, MLCC) must remain constant for PCB compatibility.

Compliance Parameters: RoHS3 compliance and MSL rating (1) are maintained across all substitutes.

Substitute parts are categorized as:

Parametric Equivalents: Identical electrical specifications (68 pF, ±2%, 50V, C0G/NP0)
Upgrades (Tolerance): Improved tolerance (±1%) with same voltage rating
Upgrades (Voltage): Higher voltage rating (100V) with improved tolerance
Direct Equivalents: Different manufacturers with identical specifications

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement): KGM21BCG1H680GT from KYOCERA AVX provides identical electrical and mechanical specifications to the discontinued 08055A680GAT2P. This part maintains ±2% tolerance and 50V rating with active product status and substantial inventory availability (13288 pcs).

Equivalent from Alternative Manufacturers: C0805C680G5GAC7800 (KEMET), CC0805GRNPO9BN680 (YAGEO), and VJ0805A680GXAPW1BC (Vishay Vitramon) are direct electrical and mechanical equivalents with ±2% tolerance and 50V rating. All maintain ROHS3 compliance and MSL 1 rating.

Tolerance-Improved Upgrades (±1%): KGM21BCG1H680FT (KYOCERA AVX), C0805C680F5GAC7800 (KEMET), and CC0805FRNPO9BN680 (YAGEO) provide improved tolerance specification while maintaining 50V rating and 0805 package compatibility. These are suitable where tighter capacitance tolerance is beneficial.

Voltage-Rated Upgrades (100V): KGM21BCG2A680FT (KYOCERA AVX) and C0805C680F1GAC7800 (KEMET) offer 100V rating with ±1% tolerance. These provide enhanced voltage margin and improved tolerance for applications requiring greater reliability headroom.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 125°C operating temperature range consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can KGM21BCG1H680GT be used as a direct replacement for 08055A680GAT2P?

A: Yes. KGM21BCG1H680GT is a parametric equivalent with identical capacitance (68 pF), tolerance (±2%), voltage rating (50V), temperature coefficient (C0G/NP0), and 0805 package. Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between ±2% and ±1% tolerance parts?

A: Tolerance specifies the allowable deviation from the nominal 68 pF value. ±2% allows ±1.36 pF deviation; ±1% allows ±0.68 pF deviation. ±1% parts provide tighter capacitance control and are suitable for applications requiring higher precision.

Q: Can a 100V rated part replace a 50V rated part?

A: Yes, from an electrical standpoint. Higher voltage rating provides additional safety margin and does not affect circuit operation in a 50V application. KGM21BCG2A680FT and C0805C680F1GAC7800 are suitable upgrades offering both 100V rating and ±1% tolerance.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitutes use the 0805 (2012 Metric) surface mount package with identical mechanical dimensions (0.079" L x 0.049" W / 2.01mm x 1.25mm). PCB footprint compatibility is maintained across all parts.

Q: What is MSL 1 rating?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture control requirements. All listed parts maintain MSL 1, requiring no special storage or handling precautions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance consistent with the original 08055A680GAT2P specification.
