Key Parameters

Substitute Part Grouping Explanation

Substitution for the P2103AC60 is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings: Breakover voltage of 250V, off-state voltage of 170V, and on-state voltage of 8V
• Current specifications: Peak pulse current of 400A (8/20µs) and 100A (10/1000µs), with hold current of 150mA
• Element configuration: Three-element design
• Capacitance characteristics: 55pF and 85pF values
• Physical package: 3-SIP through-hole configuration in TO-220 Modified form factor

The P2103ACL60 meets all these criteria and is classified as a direct manufacturer substitute.

Parameter Comparison

Engineering Selection Recommendations

The P2103ACL60 is the direct substitute for the obsolete P2103AC60. Both components share identical electrical specifications and physical packaging. The primary distinction is product status and regulatory compliance: the P2103ACL60 is active in production and ROHS3 compliant, whereas the P2103AC60 is obsolete and RoHS non-compliant. For new designs and ongoing system support, the P2103ACL60 is the appropriate selection. The P2103ACL60 is available in bulk packaging with 920 units in stock, providing supply continuity for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the P2103ACL60 directly replace the P2103AC60 in existing applications?

A: Yes. The P2103ACL60 is electrically and mechanically identical to the P2103AC60. All voltage ratings, current specifications, element configuration, and package dimensions are equivalent. Direct substitution is valid for through-hole PCB designs.

Q: What is the difference between the P2103AC60 and P2103ACL60?

A: The components are functionally identical. The P2103ACL60 is the active production variant with ROHS3 compliance, while the P2103AC60 is obsolete and RoHS non-compliant. The "L" designation in the P2103ACL60 part number indicates the lead-free, compliant version.

Q: Are there packaging differences between these parts?

A: Both parts use the same 3-SIP through-hole package in TO-220 Modified form factor. The P2103AC60 is supplied in standard packaging, while the P2103ACL60 is available in bulk packaging. PCB footprint and mounting requirements are identical.

Q: What is the inventory status for the P2103ACL60?

A: The P2103ACL60 has 920 units in stock as new original inventory, ensuring availability for immediate procurement.

Q: Are there any regulatory or compliance considerations when switching from P2103AC60 to P2103ACL60?

A: The P2103ACL60 is ROHS3 compliant and REACH unaffected, making it suitable for applications with regulatory compliance requirements. The obsolete P2103AC60 does not meet current RoHS standards.
