Substitute Part Grouping Explanation

Substitution for the VC121048G101TP is determined by strict equivalence across the following critical parameters:

• Varistor Voltage (Typical): 62 V
• Current - Surge: 220 A
• Package / Case: 1210 (3225 Metric)
• Mounting Type: Surface Mount, MLCV
• Number of Circuits: 1
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant

The substitute part VC121048G101DP meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both VC121048G101TP and VC121048G101DP are Active products with identical electrical specifications and mechanical compatibility. Selection between these part numbers may be based on inventory availability and packaging format (Tape & Reel). Both components maintain ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1), making them suitable for equivalent circuit protection applications without additional qualification requirements.

Frequently Asked Questions (FAQ)

Q: Are VC121048G101TP and VC121048G101DP electrically identical?

A: Yes. Both parts share identical electrical parameters including 62 V typical varistor voltage, 220 A surge current, 0.9 J energy rating, and 500 pF capacitance at 1 kHz. They operate across the same temperature range (-55°C to 125°C) and meet identical compliance standards.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts use identical Surface Mount MLCV mounting type and 1210 (3225 Metric) package dimensions, allowing direct substitution without PCB layout modifications.

Q: What is the difference between TP and DP packaging designations?

A: Both designations indicate Tape & Reel (TR) packaging format. The difference lies in the specific packaging configuration or reel specifications, but electrical and mechanical performance remain equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, MSL 1 rating, and EAR99 export classification.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may depend on current inventory levels, supplier availability, or existing supply chain agreements with KYOCERA AVX.
