Engineering Selection Recommendations

All three parts—VCAS121030H620DP, VC121030H620DP, and VC121030H620RP—are Active products from KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements rather than technical performance.

VCAS121030H620DP and VC121030H620DP are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. VC121030H620RP is supplied in Cut Tape (CT) & Digi-Reel® format, providing flexibility for lower-volume applications or manual assembly workflows.

All parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and storage conditions. The choice between substitutes depends on procurement volume, assembly equipment capability, and inventory management strategy.

Frequently Asked Questions (FAQ)

Q: Can VC121030H620DP replace VCAS121030H620DP in production?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications, voltage ratings, surge current capacity, and operating temperature range. The difference is packaging format: VCAS121030H620DP uses Tape & Reel (TR), while VC121030H620DP also uses Tape & Reel (TR). Both are suitable for automated assembly.

Q: What is the difference between VC121030H620DP and VC121030H620RP?

A: The electrical and mechanical specifications are identical. The difference is packaging: VC121030H620DP is supplied in Tape & Reel (TR) format, while VC121030H620RP is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and volume.

Q: Are all three parts RoHS compliant?

A: Yes. VCAS121030H620DP, VC121030H620DP, and VC121030H620RP are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. All three parts have identical electrical parameters: 41 V typical varistor voltage, 280 A surge current, 1.2 J energy rating, and -55°C to 125°C operating temperature range. They are mechanically compatible in the same 1210 (3225 Metric) package footprint.

Q: What determines substitution eligibility for this TVS varistor?

A: Substitution is based on matching varistor voltage range (36.9 V to 45.1 V), surge current rating (280 A), maximum voltage ratings (21 V AC, 30 V DC), energy capacity (1.2 J), capacitance (1850 pF @ 1 kHz), operating temperature range (-55°C to 125°C), and physical package (1210 surface mount). Packaging format differences do not affect electrical compatibility.
