P2703AC60 Equivalent & Substitute Parts

Part Overview

The P2703AC60 is a 230V off-state, 400A peak pulse thyristor transient voltage suppressor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for overvoltage protection in three-element configuration with a TO-220 Modified package. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P2703AC60 is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Breakover voltage of 300V, off-state voltage of 230V, and on-state voltage of 8V
• Current specifications: Peak pulse current of 400A (8/20µs) and 100A (10/1000µs), with hold current of 150mA
• Physical configuration: Three-element design in 3-SIP package with through-hole mounting
• Capacitance characteristics: 50pF and 75pF values

The P2703ACL60 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P2703ACL60 is the direct substitute for the obsolete P2703AC60. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status and regulatory compliance: the P2703ACL60 is currently in active production and meets ROHS3 compliance requirements, whereas the P2703AC60 is obsolete and non-compliant with current RoHS standards. For new designs and ongoing system support, the P2703ACL60 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the P2703ACL60 be used as a direct replacement for the P2703AC60?

A: Yes. The P2703ACL60 is electrically and mechanically identical to the P2703AC60 across all specified parameters, including voltage ratings, current ratings, capacitance, and package configuration.

Q: What is the difference between these two parts?

A: The P2703ACL60 is the active production equivalent of the obsolete P2703AC60. The substitute part is ROHS3 compliant, whereas the original part is non-compliant. All electrical and physical characteristics remain unchanged.

Q: Are there any compatibility concerns when substituting the P2703ACL60 for the P2703AC60?

A: No compatibility concerns exist. Both parts use the same 3-SIP package with TO-220 Modified supplier configuration and through-hole mounting. Pin configuration and functional behavior are identical.

Q: What packaging options are available for the P2703ACL60?

A: The P2703ACL60 is supplied in bulk packaging, whereas the P2703AC60 was supplied in standard packaging. Both maintain the same component specifications and performance characteristics.

Q: Are there any regulatory or compliance differences?

A: The P2703ACL60 meets ROHS3 compliance standards and is REACH unaffected. The P2703AC60 does not meet current RoHS compliance requirements. For applications subject to RoHS regulations, the P2703ACL60 is the required selection.
