Substitute Part Grouping Explanation

Substitute parts for the VCAS120642K900RP are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Varistor voltage range: 50.4 V (Min) to 61.6 V (Max), with 56 V typical
• Maximum DC voltage rating: 42 V
• Maximum AC voltage rating: 32 V
• Surge current capacity: 200 A
• Energy absorption: 0.6 J
• Capacitance at 1 kHz: 260 pF

Mechanical Parameters (Must Match Exactly):

• Package type: 1206 (3216 Metric) surface mount
• Mounting technology: MLCV (Multilayer Ceramic Varistor)
• Number of circuits: 1

Compliance & Qualification (Must Match):

• AEC-Q200 automotive qualification
• ROHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in electrical performance, package dimensions, or qualification status are permitted.

Parameter Comparison

Engineering Selection Recommendations

VCAS120642K900DP is a direct parametric equivalent to VCAS120642K900RP. Both parts are manufactured by KYOCERA AVX within the TransGuard® series and share identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Basis:

The VCAS120642K900DP meets all substitution criteria:

• Identical varistor voltage characteristics (50.4 V to 61.6 V range, 56 V typical)
• Identical surge current rating (200 A)
• Identical energy absorption capacity (0.6 J)
• Identical package configuration (1206 / 3216 Metric, surface mount MLCV)
• Identical operating temperature range (-55°C to 125°C)
• Identical compliance status (AEC-Q200, ROHS3, REACH Unaffected)
• Identical moisture sensitivity level (MSL 1)

Both parts are active in production. The difference between VCAS120642K900RP and VCAS120642K900DP is limited to packaging format designation (RP = Tape & Reel, DP = alternative packaging designation). This distinction does not affect electrical performance or mechanical compatibility in circuit applications.
