Key Parameters

Substitute Part Grouping Explanation

The P4202AB has one direct substitute: P4202ABL. Substitution eligibility is determined by matching the following critical electrical and mechanical parameters:

• Voltage ratings (Breakover: 250V, 500V; Off-State: 190V, 380V; On-State: 4V)
• Current specifications (Peak Pulse 8/20µs: 250A; Peak Pulse 10/1000µs: 80A; Hold Current: 150mA)
• Number of elements (2)
• Capacitance range (50pF, 85pF)
• Package configuration (3-SIP, TO-220 Modified)
• Mounting type (Through Hole)

The P4202ABL maintains identical electrical performance and physical form factor, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P4202ABL is the direct substitute for the obsolete P4202AB. Both components share identical electrical performance and physical specifications. The P4202ABL is currently in active production status, ensuring long-term availability and supply chain continuity.

The P4202ABL offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant P4202AB. Both components maintain the same REACH status classification and export control designation (EAR99). For new designs or system replacements, the P4202ABL is the appropriate selection due to its active product status and enhanced compliance profile.

Frequently Asked Questions (FAQ)

Q: Can P4202ABL be used as a direct replacement for P4202AB?

A: Yes. The P4202ABL is electrically and mechanically identical to the P4202AB. All voltage ratings, current specifications, capacitance values, and package configurations match exactly. The components are pin-compatible and functionally equivalent.

Q: What is the primary difference between P4202AB and P4202ABL?

A: The P4202AB is obsolete, while P4202ABL is in active production. Additionally, P4202ABL meets ROHS3 compliance standards, whereas P4202AB is non-compliant. Electrical and physical specifications are identical.

Q: Are there packaging differences between these parts?

A: The P4202AB is supplied in standard packaging, while P4202ABL is supplied in bulk packaging. Both use the same 3-SIP TO-220 Modified physical form factor and are mounted through-hole.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: breakover voltage (250V, 500V), off-state voltage (190V, 380V), on-state voltage (4V), peak pulse current ratings (250A at 8/20µs, 80A at 10/1000µs), hold current (150mA), element count (2), capacitance (50pF, 85pF), and package type (3-SIP TO-220 Modified through-hole).

Q: Is the P4202ABL suitable for new designs?

A: Yes. The P4202ABL is the recommended choice for new designs due to its active product status, ROHS3 compliance, and guaranteed long-term availability from Littelfuse Inc.
