Substitute Part Grouping Explanation

Substitution for the CQDD-25M BK is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

  • Voltage - Off State: 600 V (exact match required)
  • Package / Case: TO-263-3, D2PAK (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Operating Temperature Range: -40°C ~ 125°C (exact match required)

Secondary Compatibility Parameters:

  • Current - On State (It (RMS)): 25 A or higher
  • Voltage - Gate Trigger (Vgt): 1.5 V or lower
  • Current - Gate Trigger (Igt): 30 mA or higher
  • Current - Hold (Ih): 50 mA or higher
  • Current - Non Rep. Surge (Itsm): 150A or higher

Substitute parts are grouped into two categories:

Category 1 - Direct Current Rating Match (25A): BTA225B-600B,118 provides identical 25A on-state current rating with enhanced surge current capability and active product status.

Category 2 - Reduced Current Rating (16A or 10A): BTA316B-600B,118, BTA316B-600B0J, BTA216B-600B,118, Q6010N5TP, and Q6010N5RP provide lower on-state current ratings. These are suitable only for applications where the circuit design permits operation at reduced current levels.

Engineering Selection Recommendations

BTA225B-600B,118 is the primary substitute for the CQDD-25M BK. This part maintains the 25A on-state current rating, 600V off-state voltage, and D2PAK package configuration. The part is manufactured by WeEn Semiconductors with active product status and RoHS compliance. The operating temperature maximum of 125°C matches the original specification. Surge current capability is enhanced at 190A and 209A compared to the original 150A specification.

BTA316B-600B,118 and BTA316B-600B0J are suitable substitutes when circuit design permits operation at 16A on-state current. Both parts are active products from WeEn Semiconductors with RoHS compliance and identical package configuration. The difference between these two part numbers is packaging format: BTA316B-600B,118 is supplied in Tape & Reel, while BTA316B-600B0J is also supplied in Tape & Reel with different tape specifications.

BTA216B-600B,118 is suitable for applications requiring 16A on-state current. This part is an active product from WeEn Semiconductors with RoHS compliance and identical package configuration.

Q6010N5TP and Q6010N5RP are suitable for applications requiring 10A on-state current. Both parts are manufactured by Littelfuse Inc. with ROHS3 compliance. Q6010N5TP is supplied in Tube packaging, while Q6010N5RP is supplied in Tape & Reel. These parts maintain the full -40°C ~ 125°C operating temperature range of the original part and feature a lower gate trigger voltage of 1.3V.

Frequently Asked Questions (FAQ)

Q: Can BTA225B-600B,118 be used as a direct replacement for CQDD-25M BK?

A: Yes. BTA225B-600B,118 maintains the same 600V off-state voltage, 25A on-state current rating, D2PAK package, and surface mount configuration. The part is an active product with RoHS compliance and enhanced surge current capability.

Q: What is the difference between BTA316B-600B,118 and BTA316B-600B0J?

A: Both parts are electrically identical 16A TRIAC devices in D2PAK packages from WeEn Semiconductors. The difference is in tape specifications for reel packaging. Both are suitable for applications where 16A on-state current is acceptable.

Q: Can I use Q6010N5TP or Q6010N5RP if my circuit requires 25A?

A: No. These parts are rated for 10A on-state current maximum. Using them in a 25A application would exceed their current rating and cause device failure.

Q: What is the difference between Q6010N5TP and Q6010N5RP?

A: Both parts are electrically identical 10A TRIAC devices from Littelfuse Inc. The difference is packaging: Q6010N5TP is supplied in Tube, while Q6010N5RP is supplied in Tape & Reel.

Q: Are all substitute parts RoHS compliant?

A: Yes. BTA225B-600B,118, BTA316B-600B,118, BTA316B-600B0J, and BTA216B-600B,118 are RoHS Compliant. Q6010N5TP and Q6010N5RP are ROHS3 Compliant.

Q: Do the substitute parts have the same operating temperature range as the original CQDD-25M BK?

A: BTA225B-600B,118, BTA316B-600B,118, BTA316B-600B0J, and BTA216B-600B,118 specify a maximum operating temperature of 125°C without a minimum specification. Q6010N5TP and Q6010N5RP maintain the full -40°C ~ 125°C range of the original part.

Q: What is the significance of the gate trigger voltage difference between the original part and Q6010 series?

A: The original CQDD-25M BK has a maximum gate trigger voltage of 1.5V, while Q6010N5TP and Q6010N5RP have a maximum of 1.3V. The lower value in the Q6010 series indicates easier gate triggering. This difference is within normal design margins for TRIAC gate drive circuits.
