Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZXGD3111N8TC is determined by strict equivalence across the following critical parameters:

• Controller Type: N+1 ORing Controller with N-Channel FET configuration
• Input:Output Ratio: N:1 topology
• Switching Characteristics: 400 ns delay time for both ON and OFF transitions
• Supply Current: 200 µA maximum
• Supply Voltage Range: 4V to 20V operation
• Operating Temperature Range: -50°C to 150°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected
• Moisture Sensitivity: MSL 1 (Unlimited)

The ZXGD3111N7TC qualifies as a manufacturer-recommended substitute. Both parts share the same base product number (ZXGD3111) and are manufactured by Diodes Incorporated. The primary difference is packaging configuration: the substitute uses 7-SO with Tape & Reel delivery, while the original uses 8-SOIC. Both packages are surface-mount compatible and maintain identical electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The ZXGD3111N7TC is the manufacturer-recommended substitute for the obsolete ZXGD3111N8TC. Both components maintain identical electrical specifications and regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected).

The ZXGD3111N7TC offers the additional advantage of Active product status, ensuring continued availability and manufacturing support. The component is supplied in Tape & Reel format, which is standard for production environments.

PCB layout modifications may be required due to package differences (8-SOIC versus 7-SO). Pin configuration and lead spacing must be verified against the respective datasheets before board redesign. Both components are surface-mount compatible and maintain the same thermal and electrical performance characteristics required for N+1 ORing controller applications.

Frequently Asked Questions (FAQ)

Q: Can the ZXGD3111N7TC directly replace the ZXGD3111N8TC without circuit modifications?

A: Electrical functionality is identical. However, the package change from 8-SOIC to 7-SO requires PCB layout modifications. Pin assignments and lead spacing differ between packages, necessitating board redesign and verification.

Q: Why is the ZXGD3111N8TC classified as Obsolete?

A: The ZXGD3111N8TC has reached end-of-life status. Diodes Incorporated continues to support the N+1 ORing Controller function through the ZXGD3111N7TC, which maintains all electrical specifications while offering Active product status.

Q: Are there compliance differences between the two parts?

A: No. Both the ZXGD3111N8TC and ZXGD3111N7TC are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory compliance is equivalent.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging. The ZXGD3111N8TC uses 8-SOIC packaging, while the ZXGD3111N7TC uses 7-SO packaging. Electrical performance, supply voltage range (4V to 20V), switching delays (400 ns), and operating temperature range (-50°C to 150°C) are identical.

Q: Is the ZXGD3111N7TC available in the same quantities as the original part?

A: The ZXGD3111N7TC is supplied in Tape & Reel format and maintains Active product status with established supply channels. The ZXGD3111N8TC is Obsolete with limited remaining inventory.
