Key Parameters

Substitute Part Grouping Explanation

Substitution for the ROV07-241K is determined by the following critical parameters:

• Maximum AC Volts: 150 V
• Maximum DC Volts: 200 V
• Varistor Voltage (Typ): 240 V
• Current - Surge: 1.2 kA minimum
• Mounting Type: Through Hole
• Package / Case: Disc 7mm or compatible disc form factor
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents (1.2 kA surge current) Parts that match the exact surge current rating of 1.2 kA with identical voltage specifications and through-hole disc mounting.

Category 2: Enhanced Performance Alternatives (1.75 kA surge current) Parts that exceed the surge current rating to 1.75 kA while maintaining voltage specifications and mounting compatibility. These provide higher transient energy absorption capacity.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended for Pin-Compatible Replacement)

The B72207S series from EPCOS - TDK Electronics (B72207S0151K101, B72207S0151K111, B72207S0151K211) provides direct electrical equivalence with identical 1.2 kA surge current and 240 V varistor voltage specifications. All three variants are active products with ROHS3 compliance. Selection among these three depends on packaging requirements: B72207S0151K101 is supplied in bulk, while B72207S0151K111 and B72207S0151K211 are supplied in cut tape format with higher inventory availability (7,116 and 28,540 units respectively).

Littelfuse Active Alternative

The V07E150P from Littelfuse Inc. maintains manufacturer continuity and is an active product with enhanced surge current rating of 1.75 kA. This part operates within a narrower temperature range (-55°C ~ 85°C) compared to the original ROV07-241K (-40°C ~ 125°C) and is designated as part of the UltraMOV™ series.

Enhanced Performance Alternatives

The ERZ-V07D241 from Panasonic Electronic Components and CV150K07B-05 from Stackpole Electronics Inc. both provide 1.75 kA surge current with higher energy absorption (21 J and 18 J respectively). The ERZ-V07D241 uses a slightly larger disc form factor (8.5mm versus 7mm), which may require PCB layout verification. The CV150K07B-05 maintains the 7mm disc form factor and offers the highest energy rating at 18 J.

All substitute parts maintain the critical electrical parameters (150 V AC maximum, 200 V DC maximum, 240 V typical varistor voltage) and through-hole mounting configuration required for functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher surge current rating (1.75 kA) in place of the 1.2 kA ROV07-241K?

A: Yes. Higher surge current ratings provide enhanced transient protection capability. The 1.75 kA alternatives (V07E150P and ERZ-V07D241) maintain all critical voltage specifications and mounting compatibility, making them suitable for direct substitution with improved performance margin.

Q: What is the difference between the three B72207S variants?

A: B72207S0151K101, B72207S0151K111, and B72207S0151K211 are electrically identical with matching 1.2 kA surge current and 240 V varistor voltage. The differences are packaging format (bulk versus cut tape) and inventory availability. Selection depends on procurement and assembly requirements.

Q: Does the ERZ-V07D241 with 8.5mm disc form factor fit the same PCB footprint as the 7mm ROV07-241K?

A: The ERZ-V07D241 uses a larger disc diameter (8.5mm versus 7mm). PCB layout verification is required to confirm mechanical fit. If space constraints exist, the 7mm alternatives (B72207S series, V07E150P, or CV150K07B-05) are recommended.

Q: Are all substitute parts RoHS3 compliant?

A: The B72207S series, V07E150P, and ERZ-V07D241 are confirmed ROHS3 compliant. The CV150K07B-05 RoHS status is not specified in the provided data and should be verified with the manufacturer or distributor.

Q: What is the operating temperature range consideration for substitution?

A: The original ROV07-241K operates from -40°C to 125°C. Most substitutes operate within -40°C to 85°C or -40°C to 105°C ranges. If the application requires operation above 105°C, the original part's extended temperature range may be necessary. Verify application temperature requirements before selection.

Q: Can I substitute the ROV07-241K with a part from a different manufacturer?

A: Yes. All listed substitutes from EPCOS - TDK Electronics, Panasonic, and Stackpole Electronics maintain the critical electrical parameters and mounting specifications. Manufacturer selection depends on supply chain, cost, and availability requirements.
