VE17M00461K-- Equivalent & Substitute Parts

Part Overview

The VE17M00461K-- is a 750 V, 4.5 kA Transient Voltage Suppressor (TVS) varistor manufactured by KYOCERA AVX in a 17mm disc through-hole package. This component is designed for transient overvoltage protection in electronic circuits with a maximum energy rating of 47J and operating temperature range of -40°C to 125°C.

The VE17M00461K-- has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VE17M00461K-- are selected based on the following critical electrical and mechanical parameters:

Electrical equivalence is established through matching varistor voltage specifications (675 V minimum to 825 V maximum range), surge current rating (4.5 kA), and maximum AC/DC voltage ratings. All substitute parts maintain the same 750 V typical varistor voltage and 4.5 kA surge current capacity.

Mechanical compatibility is determined by through-hole mounting type and single-circuit configuration. While the substitute parts use 14mm disc packages (compared to the original 17mm), they maintain the same functional footprint category and through-hole mounting methodology.

The identified substitutes are:

• B72214S0461K101 (EPCOS - TDK Electronics)
• V480LA40AP (Littelfuse Inc.)

Both substitutes meet the core electrical requirements and are currently in active product status with improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts provide active product status with current manufacturing support, addressing the obsolescence of the VE17M00461K--.

B72214S0461K101 (EPCOS - TDK Electronics) maintains the closest electrical specifications to the original part, with identical maximum AC/DC voltage ratings and operating temperature minimum of -40°C. This part achieves ROHS3 compliance and provides 100J energy rating, exceeding the original 47J specification. The 14mm disc package represents a reduced physical footprint while maintaining through-hole mounting compatibility.

V480LA40AP (Littelfuse Inc.) offers enhanced maximum voltage ratings (480V AC, 640V DC) and extended low-temperature operation (-55°C), providing broader application flexibility. This part also achieves ROHS3 compliance with 105J energy rating. The operating temperature maximum of 85°C is lower than the original specification, requiring evaluation against specific application thermal requirements.

Both substitutes are ROHS3 compliant and REACH unaffected, supporting modern regulatory requirements. Selection between these options depends on specific thermal operating conditions and physical space constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can B72214S0461K101 and V480LA40AP be used interchangeably with VE17M00461K--?

A: Both parts meet the core electrical requirements (750V typical varistor voltage, 4.5kA surge current). However, physical package differences (14mm vs. 17mm disc) require PCB layout verification. Operating temperature ranges differ; B72214S0461K101 maintains -40°C minimum, while V480LA40AP operates to -55°C but only to 85°C maximum. Application thermal requirements must be evaluated.

Q: What is the impact of the package size change from 17mm to 14mm?

A: The 14mm disc package reduces physical footprint while maintaining through-hole mounting methodology. PCB hole spacing and component clearance must be verified against original design specifications. Both substitute parts use identical mounting type (through hole), simplifying mechanical integration.

Q: Why do the substitute parts have higher energy ratings (100J and 105J vs. 47J)?

A: Higher energy ratings indicate enhanced transient suppression capability. These values are provided specifications for the substitute parts and represent improved performance margins. Application circuit requirements determine whether this additional capacity is beneficial or unnecessary.

Q: Are there compliance differences between the original and substitute parts?

A: The original VE17M00461K-- is RoHS non-compliant. Both substitutes achieve ROHS3 compliance, supporting modern manufacturing and environmental regulations. All three parts are REACH unaffected and carry EAR99 ECCN classification.

Q: Which substitute part should be selected for high-temperature applications?

A: B72214S0461K101 supports operation to 105°C, compared to V480LA40AP at 85°C maximum. For applications requiring the original -40°C to 125°C range, neither substitute fully matches the upper temperature limit. Application thermal analysis is required to determine acceptability.
