Equivalent & Substitute Parts for 16VT210LU

Part Overview

The 16VT210LU is a polymeric PTC resettable fuse manufactured by Littelfuse Inc. as part of the POLY-FUSE® VT series. This component provides overcurrent protection with a 16V maximum voltage rating and 2.1A hold current specification. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar protection characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 16VT210LU is determined by the following critical parameters:

• Voltage Rating: The substitute must support the maximum voltage requirement of 16V or higher
• Current Characteristics: Hold current (Ih), trip current (It), and maximum current must match or exceed the original specification
• Thermal Performance: Operating temperature range and time-to-trip response must be compatible
• Electrical Properties: Initial and post-trip resistance values must fall within acceptable ranges
• Physical Form Factor: Strap package configuration with compatible dimensions
• Regulatory Compliance: cURus and TUV certifications with ROHS3 compliance

The MF-VS210L-0 from Bourns Inc. shares identical current characteristics (2.1A hold, 4.7A trip), thermal response (5s trip time), and electrical properties (18 mOhms initial, 60 mOhms post-trip resistance). However, the voltage rating of 12V is lower than the 16V requirement of the original part, which represents a critical limitation for direct substitution in circuits designed for 16V operation.

Parameter Comparison

Engineering Selection Recommendations

The MF-VS210L-0 demonstrates functional equivalence in current protection characteristics, thermal response, and regulatory compliance. Both components carry cURus and TUV certifications and maintain ROHS3 compliance. The MF-VS210L-0 is currently in active production status, providing supply continuity for the obsolete 16VT210LU.

The voltage rating differential (12V versus 16V) must be evaluated against the actual operating voltage of the target application. Selection of the MF-VS210L-0 is appropriate only for circuits operating at or below 12V maximum voltage. For applications requiring full 16V voltage margin, alternative components with matching 16V or higher voltage ratings must be identified.

Frequently Asked Questions (FAQ)

Q: Can the MF-VS210L-0 directly replace the 16VT210LU in all applications?

A: Direct replacement is limited by voltage rating. The MF-VS210L-0 is rated for 12V maximum, while the 16VT210LU is rated for 16V. Substitution is valid only for circuits operating at 12V or below.

Q: Are the current protection characteristics identical between these parts?

A: Yes. Both components specify 2.1A hold current, 4.7A trip current, 100A maximum current, and 5-second trip time. Electrical resistance values (18 mOhms initial, 60 mOhms post-trip) are also identical.

Q: Do both parts meet the same regulatory standards?

A: Both the 16VT210LU and MF-VS210L-0 carry cURus and TUV certifications and are ROHS3 compliant. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: What is the physical compatibility between these strap-package components?

A: Both components use strap packaging with similar dimensions. The 16VT210LU measures 0.984" L x 0.201" W x 0.032" thick, while the MF-VS210L-0 measures 0.984" L x 0.205" W x 0.035" thick. Dimensional differences are minimal and typically accommodate standard strap mounting configurations.

Q: Why is the 16VT210LU listed as obsolete?

A: Product status reflects manufacturer discontinuation. The MF-VS210L-0 from Bourns provides an active production alternative with equivalent current and thermal characteristics for compatible voltage applications.
