Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V175LC10AP are qualified based on matching the following critical electrical and mechanical parameters:

• Maximum AC Volts: 175 V
• Maximum DC Volts: 225 V
• Varistor Voltage (Typical): 270 V
• Current - Surge: 4.5 kA
• Mounting Type: Through Hole
• Package / Case: Disc 14mm
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria: the V175LA10AP (Littelfuse Inc., LA series) and the B72214S0171K101 (EPCOS - TDK Electronics, Standard series). Both maintain identical electrical performance specifications and physical form factor compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V175LC10AP, V175LA10AP, and B72214S0171K101—are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain requirements. The V175LA10AP offers higher inventory availability (17,190 units) compared to the main part (935 units). The B72214S0171K101 from EPCOS - TDK Electronics provides an alternative cross-manufacturer option with 14,424 units in stock. All three parts are suitable for direct substitution in applications requiring 270 V varistor protection with 4.5 kA surge current handling in a through-hole disc configuration.

Frequently Asked Questions (FAQ)

Q: Can V175LA10AP be used as a direct replacement for V175LC10AP?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications (175 V AC maximum, 225 V DC maximum, 270 V typical varistor voltage, 4.5 kA surge current) and physical form factor (14mm disc through-hole package). The difference is the series designation (LA versus LC).

Q: What are the differences between the Littelfuse and EPCOS substitutes?

A: The V175LA10AP and B72214S0171K101 both meet the core electrical and mechanical requirements. The B72214S0171K101 has a slightly lower energy rating (46 J versus 55 J) and a different operating temperature range (-40°C ~ 105°C versus -55°C ~ 85°C). Capacitance specifications also differ slightly (670 pF @ 1 kHz versus 700 pF @ 1 MHz).

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All three parts—V175LC10AP, V175LA10AP, and B72214S0171K101—are ROHS3 compliant and REACH unaffected.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All three parts use identical through-hole disc 14mm packaging and mounting type, making them mechanically and electrically interchangeable in circuit designs requiring 270 V varistor protection with 4.5 kA surge current capacity.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability and preferred manufacturer. The V175LA10AP offers the highest current inventory (17,190 units). The B72214S0171K101 provides cross-manufacturer sourcing from EPCOS - TDK Electronics. All parts meet identical functional requirements for 270 V overvoltage protection applications.
