V575LC10P Equivalent & Substitute Parts

Part Overview

The V575LC10P is a 910 V, 2.5 kA disc varistor manufactured by Littelfuse Inc. in the LC series. This transient voltage suppressor is designed for through-hole mounting applications requiring overvoltage protection in circuits with maximum AC voltage ratings of 575 V and maximum DC voltage ratings of 730 V. The part is currently active in production with full inventory availability. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design standardization, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

The V575LA10P is identified as a parametric equivalent to the V575LC10P based on the following substitution criteria:

Electrical Parameters (Identical):

• Maximum AC Volts: 575 V
• Maximum DC Volts: 730 V
• Varistor Voltage (Min/Typ/Max): 819 V / 910 V / 1.001 kV
• Current - Surge: 2.5 kA
• Energy: 65 J
• Number of Circuits: 1
• Capacitance @ 1 MHz: 90 pF
• Operating Temperature Range: -55°C to 85°C

Mechanical Parameters (Identical):

• Mounting Type: Through Hole
• Package / Case: Disc 10mm

Compliance & Certification (Identical):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8533.40.4000

The only difference between these parts is the internal series designation (LC versus LA), which does not affect electrical or mechanical performance within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the V575LC10P and V575LA10P are active production parts manufactured by Littelfuse Inc. with identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts may be based on inventory availability or procurement lead time, as both parts meet ROHS3 compliance and carry unlimited moisture sensitivity rating (MSL 1). The V575LA10P currently maintains higher inventory levels (6026 pcs versus 899 pcs for the V575LC10P), which may influence supply chain decisions. Both parts are suitable for direct substitution in through-hole disc varistor applications requiring 910 V nominal protection at 2.5 kA surge current capacity.

Frequently Asked Questions (FAQ)

Q: Can the V575LA10P be used as a direct replacement for the V575LC10P?

A: Yes. Both parts are identical in all electrical parameters (voltage ratings, surge current, energy capacity), mechanical specifications (through-hole mounting, 10mm disc package), and compliance certifications (ROHS3, MSL 1, REACH status). The series designation (LC versus LA) does not affect functional performance.

Q: Are there any differences in operating temperature range between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 85°C.

Q: Do both parts have the same capacitance characteristics?

A: Yes. Both parts measure 90 pF capacitance at 1 MHz frequency.

Q: What is the significance of the series designation (LC versus LA)?

A: The series designation indicates internal manufacturing series but does not affect the electrical or mechanical performance of the varistor within the specified parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both the V575LC10P and V575LA10P are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

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

A: Yes. Both parts share identical through-hole mounting specifications and 10mm disc package dimensions, allowing direct PCB layout compatibility.
