Substitute Part Grouping Explanation

Substitute parts for the P4SMA190CA TR13 are identified based on matching the following critical electrical and mechanical parameters:

• Reverse standoff voltage: 190V
• Peak pulse current: 1.3A
• Peak pulse power dissipation: 400W
• Clamping voltage range: within acceptable tolerance of 308V
• Package type: DO-214AC / SMA surface mount
• Operating temperature range: -55°C ~ 150°C
• Zener diode type with single bidirectional channel

The TV04A191JB-G from Comchip Technology meets all substitution criteria and is classified as an active product, providing improved supply chain availability compared to the obsolete P4SMA190CA TR13.

Parameter Comparison

• Electrical parameter equivalence across all critical specifications
• Active product status ensuring current manufacturing and supply availability
• Identical package and mounting configuration (DO-214AC / SMA surface mount)
• Matching operating temperature range (-55°C ~ 150°C)
• RoHS3 compliance and REACH unaffected status, supporting modern regulatory requirements
• Tape & Reel packaging suitable for automated assembly processes

The TV04A191JB-G provides direct functional replacement with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can the TV04A191JB-G be used as a direct replacement for the P4SMA190CA TR13 without circuit modifications?

A: Yes. The TV04A191JB-G matches all critical electrical parameters (190V standoff, 1.3A peak pulse current, 400W power dissipation) and uses the identical DO-214AC / SMA package. No circuit design changes are necessary.

Q: What is the difference in clamping voltage between these parts?

A: The P4SMA190CA TR13 specifies 308V maximum clamping voltage, while the TV04A191JB-G specifies 307.8V. This 0.2V difference is within acceptable tolerance for TVS diode applications and does not affect functional compatibility.

Q: Why is the P4SMA190CA TR13 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The TV04A191JB-G, classified as active, is currently manufactured and represents the recommended alternative for new designs and ongoing production requirements.

Q: Are there any compliance differences between these parts?

A: The TV04A191JB-G includes RoHS3 compliance and REACH unaffected status certifications. Both parts carry EAR99 ECCN classification and identical HTSUS codes, supporting equivalent regulatory and export requirements.

Q: What packaging options are available for the TV04A191JB-G?

A: The TV04A191JB-G is supplied in Tape & Reel (TR) packaging, optimized for automated surface mount assembly processes. The physical package remains DO-214AC / SMA, maintaining PCB footprint compatibility with the original P4SMA190CA TR13.
