VCAS080538C770DP Equivalent & Substitute Parts

Part Overview

The VCAS080538C770DP is a 47 V, 80 A Transient Voltage Suppressor (TVS) varistor manufactured by KYOCERA AVX in the FLEXITERM® series. This surface mount component in 0805 (2012 Metric) package format is designed for transient voltage protection in electronic circuits. The part maintains Active product status with automotive-grade qualification (AEC-Q200) and is RoHS3 compliant. Alternative equivalent components become necessary when primary part availability is limited, when specific packaging formats are required, or when supply chain optimization requires cross-manufacturer sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for varistor components is determined by electrical parameter compatibility within tolerance limits and mechanical compatibility. The following key parameters establish substitution validity:

• Varistor Voltage Range: Minimum 42.3 V to Maximum 51.7 V (nominal 47 V)
• Surge Current Rating: 80 A minimum
• Maximum DC Operating Voltage: 38 V
• Maximum AC Operating Voltage: 30 V
• Energy Absorption: 0.3 J
• Package Format: 0805 (2012 Metric) surface mount
• Mounting Configuration: MLCV designation
• Operating Temperature: -55°C ~ 125°C

All listed substitute parts meet or exceed these electrical and mechanical requirements. Packaging options (Tape & Reel, Cut Tape, or Digi-Reel®) are logistical variants that do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the VCAS080538C770DP and maintain full compliance with RoHS3 and REACH regulations. Selection among these equivalents should be based on:

KYOCERA AVX Parts (VC080538C770DP, VCAS080538C770RP): Both maintain the FLEXITERM® or TransGuard® series designation with Active product status and AEC-Q200 automotive qualification. These variants differ only in packaging format (Tape & Reel options) and offer the highest supply availability for KYOCERA AVX sourcing continuity.

EPCOS - TDK Electronics (B72510T0300K062): Provides cross-manufacturer equivalence with identical electrical specifications and the same 0805 package format. This part is supplied in Cut Tape & Digi-Reel® format and maintains comparable availability and compliance certifications.

All parts meet -55°C to 125°C operating temperature requirements, suitable for automotive and industrial applications requiring AEC-Q200 qualification or equivalent reliability standards.

Frequently Asked Questions (FAQ)

Q: Can VC080538C770DP be used as a direct replacement for VCAS080538C770DP?

A: Yes. Both parts are manufactured by KYOCERA AVX with identical electrical parameters (47 V typical varistor voltage, 80 A surge current, 38 V maximum DC, 0.3 J energy absorption) and the same 0805 (2012 Metric) surface mount package. The difference is packaging format only (Tape & Reel variant).

Q: Is the B72510T0300K062 from EPCOS suitable for automotive applications?

A: Yes. The B72510T0300K062 meets all electrical requirements equivalent to the KYOCERA AVX VCAS080538C770DP and is RoHS3 compliant with MSL 1 rating. However, verify specific automotive grade requirements (AEC-Q200) with your application specifications, as the provided data does not indicate specific automotive qualification for this EPCOS variant.

Q: What are the key differences between these substitute parts?

A: All parts are electrically identical across critical parameters: 47 V varistor voltage, 80 A surge current, 38 V maximum DC voltage, and 0.3 J energy absorption. Differences exist only in manufacturer (KYOCERA AVX versus EPCOS - TDK Electronics) and packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Package format affects logistics and handling but not electrical performance or PCB placement.

Q: Can packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel®) is a supply and logistics specification that does not affect the electrical performance or PCB placement of the varistor component. All formats contain identical parts.

Q: Are these parts interchangeable on a PCB without design changes?

A: Yes. All substitute parts share the identical 0805 (2012 Metric) MLCV surface mount package footprint. No PCB layout or design modifications are required for substitution among these listed parts.
