V130LS1P Equivalent & Substitute Parts

Part Overview

The V130LS1P is a 220 V varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This through-hole disc component rated at 1.2 kA surge current and 11 J energy dissipation is actively produced and widely stocked. Equivalent parts are identified to support procurement flexibility, supply chain continuity, and application-specific requirements where the primary part may be unavailable or where alternative specifications better match circuit design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V130LS1P is determined by the following critical parameters:

• Varistor voltage rating within the specified tolerance band (198 V to 242 V for the main part)
• Surge current capacity of 1.2 kA minimum
• Through-hole mounting configuration with disc 7mm package geometry
• Maximum AC voltage rating of 130 V or greater
• Maximum DC voltage rating of 170 V or greater
• RoHS3 compliance and REACH unaffected status

The B72207S0131K111 manufactured by EPCOS - TDK Electronics meets these substitution criteria. While the typical varistor voltage is 205 V (lower than the 220 V main part), the tolerance band (184.5 V to 225.5 V) overlaps with the V130LS1P specification range, permitting direct substitution in applications where the circuit design accommodates this voltage variation.

Parameter Comparison

Engineering Selection Recommendations

Both the V130LS1P and B72207S0131K111 are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The V130LS1P offers higher maximum DC voltage (175 V vs. 170 V) and greater energy dissipation capacity (11 J vs. 9.5 J). Selection of the V130LS1P is appropriate for applications requiring maximum thermal margin or operating near the upper DC voltage limit.

The B72207S0131K111 provides equivalent surge current handling (1.2 kA) and identical AC voltage rating (130 V). The lower typical varistor voltage (205 V vs. 220 V) and reduced energy rating (9.5 J vs. 11 J) are acceptable in applications where circuit design parameters accommodate these specifications. The B72207S0131K111 offers significantly higher inventory availability (16,975 pcs vs. 831 pcs).

Frequently Asked Questions (FAQ)

Q: Can the B72207S0131K111 directly replace the V130LS1P in all applications?

A: Direct substitution is valid when the circuit design accommodates the lower typical varistor voltage (205 V vs. 220 V) and reduced energy dissipation (9.5 J vs. 11 J). Both parts share identical surge current (1.2 kA), AC voltage rating (130 V), mounting type (through-hole), and package geometry (disc 7mm). Verify that the application's voltage tolerance band accepts the B72207S0131K111 specification range of 184.5 V to 225.5 V.

Q: What is the significance of the varistor voltage tolerance band?

A: The varistor voltage tolerance band defines the acceptable operating range for the component. The V130LS1P operates between 198 V and 242 V, while the B72207S0131K111 operates between 184.5 V and 225.5 V. The overlapping range (198 V to 225.5 V) permits substitution in circuits designed for this common window.

Q: Are there packaging differences between these parts?

A: Both parts use identical through-hole disc 7mm packaging and mounting configuration. The V130LS1P is supplied in tape and reel (TR) format, while the B72207S0131K111 is supplied in cut tape (CT) format. Both formats are compatible with standard PCB assembly processes.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the V130LS1P and B72207S0131K111 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement and use.

Q: Which part should be selected for new designs?

A: Selection depends on application-specific requirements. For maximum performance margin and energy dissipation capacity, select the V130LS1P. For applications where the lower specifications are acceptable and higher inventory availability is beneficial, select the B72207S0131K111. Both parts are active products suitable for new designs.
