V140LA10C Equivalent & Substitute Parts

Part Overview

The V140LA10C is a 220 V varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This through-hole disc component (14mm) provides 6.5 kA surge current protection with 90 J energy absorption capacity. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

The V140LA10CP qualifies as a direct substitute for the V140LA10C based on the following critical parameters:

• Varistor Voltage (Typical): Identical at 220 V with matching tolerance range (198 V – 242 V)
• Surge Current Rating: Identical at 6.5 kA
• Energy Absorption: Identical at 90 J
• Maximum AC Volts: Identical at 140 V
• Electrical Characteristics: Capacitance, operating temperature range, and circuit count are identical
• Physical Form Factor: Both use through-hole mounting with 14mm disc package
• Compliance Standards: Both are ROHS3 compliant with MSL 1 rating

The primary distinction is product status: V140LA10C is obsolete, while V140LA10CP is active production. The packaging difference (tape/reel vs. bulk) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The V140LA10CP is the appropriate selection for applications currently specified with V140LA10C. Both parts are manufactured by Littelfuse Inc. within the same C-III series and maintain identical electrical and mechanical specifications. The V140LA10CP offers the advantage of active production status, ensuring long-term availability and supply chain continuity. Both parts meet ROHS3 compliance requirements and carry equivalent environmental certifications. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can V140LA10CP be used as a direct replacement for V140LA10C?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including varistor voltage (220 V typical), surge current (6.5 kA), energy absorption (90 J), and physical form factor (14mm disc through-hole). The primary difference is product status: V140LA10C is obsolete while V140LA10CP is in active production.

Q: What is the difference between V140LA10C and V140LA10CP?

A: The parts are functionally equivalent. The suffix "P" in V140LA10CP indicates packaging in bulk format, whereas V140LA10C may have been supplied in alternative packaging. Both maintain identical electrical characteristics and compliance certifications.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with MSL 1 rating and carry the same ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What is the operating temperature range for these varistors?

A: Both V140LA10C and V140LA10CP operate across -55°C to 85°C ambient temperature range.

Q: Can these parts be used in new designs?

A: V140LA10CP is recommended for new designs due to its active production status. V140LA10C is obsolete and should not be specified for new applications.
