Substitute Part Grouping Explanation

Substitute parts for the VC120618D400RP are qualified based on identical electrical performance parameters and mechanical compatibility. The substitution criteria are:

Varistor voltage range: 22.95 V (Min) to 28.05 V (Max)
Surge current rating: 150 A
DC voltage rating: 18 V maximum
AC voltage rating: 13 V maximum
Energy absorption: 0.4 J
Package format: 1206 (3216 Metric) surface mount
Operating temperature: -55°C to 125°C
Moisture sensitivity level: 1 (Unlimited)
RoHS3 compliance

All substitute parts listed maintain these electrical and mechanical specifications. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel®) do not affect electrical performance and are determined by procurement and assembly requirements.

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. Selection between substitute options is determined by packaging requirements and inventory availability rather than electrical performance differences.

VC120618D400DP and VCAS120618D400RP offer Cut Tape & Digi-Reel® packaging, suitable for applications requiring flexible tape formats or lower volume procurement. VCAS120618D400DP and VCAS120618D400DZ are supplied in Tape & Reel format, appropriate for high-volume automated assembly operations.

VCAS120618D400DZ is qualified to AEC-Q200 automotive standards and carries FLEXITERM® series designation, making it suitable for automotive and harsh environment applications where additional qualification is required.

All parts are REACH Unaffected and classified under ECCN EAR99, with identical HTSUS coding (8533.40.4000), supporting consistent supply chain documentation and compliance tracking.

Frequently Asked Questions (FAQ)

Q: Can VC120618D400RP be directly replaced with VC120618D400DP?

A: Yes. Both parts share identical electrical specifications (25.5 V varistor voltage, 150 A surge current, 0.4 J energy) and 1206 package format. The difference is packaging format: VC120618D400RP uses Tape & Reel, while VC120618D400DP uses Cut Tape & Digi-Reel®. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: What is the difference between TransGuard® and FLEXITERM® series parts?

A: Both series meet identical electrical and mechanical specifications for this 25.5 V, 150 A varistor. VCAS120618D400DZ (FLEXITERM® series) carries AEC-Q200 automotive qualification, making it suitable for automotive applications. TransGuard® series parts are suitable for general industrial and consumer applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and reliability standards.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging formats do not affect electrical performance. Selection is based on assembly process requirements and equipment compatibility.

Q: Can VCAS120618D400DZ be used in non-automotive applications?

A: Yes. VCAS120618D400DZ meets all electrical and mechanical specifications for general use. AEC-Q200 qualification indicates additional automotive-grade testing and reliability assurance, but the part is suitable for any application requiring 25.5 V, 150 A varistor protection.

Q: What inventory considerations apply to substitute selection?

A: VC120618D400DP has the highest inventory (16066 Pcs), followed by VCAS120618D400DZ (4696 Pcs) and VCAS120618D400RP (4529 Pcs). Inventory levels support procurement planning and lead time management based on application volume requirements.
