Substitute Part Grouping Explanation

Substitute parts for the VCAS120626D580DP are qualified based on strict electrical and mechanical parameter matching:

Substitution Criteria:

• Varistor voltage range: 31.05 V (Min) to 37.95 V (Max)
• Surge current rating: 120 A
• Energy dissipation: 0.4 J
• Package: 1206 (3216 Metric) surface mount
• Mounting type: MLCV surface mount
• Operating temperature: -55°C to 125°C
• Compliance: ROHS3, REACH Unaffected
• Series: TransGuard®
• Manufacturer: KYOCERA AVX

The identified substitutes (VC120626D580DP and VC120626D580RP) meet all these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (VCAS120626D580DP, VC120626D580DP, and VC120626D580RP) are Active status components from KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability:

• VCAS120626D580DP: 764 Pcs in stock
• VC120626D580DP: 2320 Pcs in stock
• VC120626D580RP: 4060 Pcs in stock

All parts carry ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Are VC120626D580DP and VC120626D580RP direct substitutes for VCAS120626D580DP?

A: Yes. All three part numbers are electrically and mechanically identical. They share the same varistor voltage (34.5 V typical), surge current rating (120 A), energy dissipation (0.4 J), package (1206 / 3216 Metric), and operating temperature range (-55°C to 125°C). They are interchangeable in circuit design and PCB layout.

Q: What determines substitutability for this TVS varistor?

A: Substitutability is determined by matching varistor voltage specifications (31.05 V to 37.95 V range), surge current capacity (120 A), energy rating (0.4 J), package type (1206 surface mount), and compliance certifications (ROHS3, REACH Unaffected). All three parts meet these criteria.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. The identical 1206 (3216 Metric) package and surface mount MLCV mounting type ensure mechanical and electrical compatibility on the same PCB footprint without design modifications.

Q: Are there any compliance differences between these part numbers?

A: No. All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited). Compliance certifications are identical across all substitute options.

Q: What is the difference between these part numbers if they are identical?

A: The part numbers differ in their packaging designation suffix (D580DP vs. D580RP vs. the main VCAS prefix). These designations reflect internal KYOCERA AVX manufacturing or distribution codes but do not affect electrical performance or mechanical compatibility.
