ROV07-101K-S Equivalent & Substitute Parts

Part Overview

The ROV07-101K-S is a 100 V, 1.2 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a 7mm disc through-hole package. This component is designed for transient voltage protection in electronic circuits and is currently classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROV07-101K-S is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Varistor Voltage (Typ): 100 V (range 90 V - 110 V acceptable)
• Current - Surge: 1.2 kA minimum
• Maximum DC Volts: 85 V
• Maximum AC Volts: 60 V
• Mounting Type: Through Hole
• Package / Case: Disc format (7mm or 9mm acceptable with mechanical verification)
• Number of Circuits: 1

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Substitute parts are grouped into two categories based on package compatibility:

Group 1 - Direct Package Match (Disc 7mm): V100ZA3P, B72207S0600K111, B72207S0600K211, MOV-07D101K, MOV-07D101KTR

Group 2 - Package Variant (Disc 8.5mm or 9mm): ERZ-V07D101, VDRS07H060BSE

All listed substitutes maintain the core electrical specifications and compliance certifications required for equivalent functionality.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products from established manufacturers with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and long-term availability.

For direct replacement with identical package dimensions (Disc 7mm):

• V100ZA3P (Littelfuse Inc.) - Same manufacturer as original, active product status
• B72207S0600K111 or B72207S0600K211 (EPCOS - TDK Electronics) - Established manufacturer, cut tape packaging available
• MOV-07D101K or MOV-07D101KTR (Bourns Inc.) - Active product, available in bulk and cut tape formats

For applications where package size variation is acceptable:

• ERZ-V07D101 (Panasonic Electronic Components) - Disc 8.5mm package, higher surge current rating (1.75 kA)
• VDRS07H060BSE (Vishay Beyschlag/Draloric/BC Components) - Disc 9mm package, higher energy rating (8.3 J)

Selection should prioritize parts with active product status and established supply chain availability. Package dimension verification is required when substituting parts with different disc sizes.

Frequently Asked Questions (FAQ)

Q: Can V100ZA3P be used as a direct replacement for ROV07-101K-S?

A: V100ZA3P is electrically compatible with matching varistor voltage (100 V typ), surge current (1.2 kA), and package format (Disc 7mm). However, the maximum DC voltage specification is 81 V compared to 85 V for the original part. Verify that your circuit design operates within the 81 V maximum DC rating before substitution.

Q: What is the difference between MOV-07D101K and MOV-07D101KTR?

A: Both parts are identical electrically and mechanically. The difference is packaging format: MOV-07D101K is supplied in bulk, while MOV-07D101KTR is supplied in cut tape (CT) format. Selection depends on your procurement and assembly requirements.

Q: Can ERZ-V07D101 be used as a substitute despite the different package size (Disc 8.5mm)?

A: ERZ-V07D101 meets all electrical specifications and maintains through-hole mounting compatibility. The package size difference (8.5mm vs. 7mm) requires mechanical verification to confirm PCB hole spacing and component clearance compatibility. Higher surge current (1.75 kA) and energy rating (8.5 J) provide enhanced transient protection capability.

Q: Why does VDRS07H060BSE have a larger package (Disc 9mm)?

A: The larger disc format (9mm) accommodates higher energy dissipation (8.3 J) while maintaining the same electrical specifications. Mechanical verification of PCB layout is required before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the operating temperature range consideration when selecting a substitute?

A: The original ROV07-101K-S operates from -40°C to 125°C. Most substitute parts operate from -40°C to 85°C or -40°C to 105°C. Verify that your application's operating temperature requirements fall within the selected substitute part's rated range.
