Substitute Part Grouping Explanation

Substitution eligibility for the V175LS20APX2855 is determined by strict equivalence across all electrical parameters and mechanical form factor. The primary substitution criterion is packaging format. The V175LS20APX2855 is supplied in tape and reel (TR) format, while the V175LS20AP is supplied in cut tape (CT) format. Both parts share identical electrical specifications: 175 V maximum AC rating, 225 V maximum DC rating, 270 V typical varistor voltage, 6.5 kA surge current capacity, and 90 J energy absorption. Both maintain the same through-hole disc 20mm package configuration, operating temperature range of -55°C to 85°C, and compliance certifications including ROHS3. The substitution is valid when packaging format flexibility is acceptable for the application's procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the V175LS20APX2855 and V175LS20AP are active production components from Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The V175LS20APX2855 in tape and reel format is suitable for high-volume automated assembly operations. The V175LS20AP in cut tape format accommodates lower-volume applications or manual assembly processes. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between V175LS20APX2855 and V175LS20AP?

A: The parts are electrically and mechanically identical. The only difference is packaging format: V175LS20APX2855 is supplied in tape and reel (TR) format, while V175LS20AP is supplied in cut tape (CT) format.

Q: Can V175LS20AP be used as a direct replacement for V175LS20APX2855?

A: Yes, V175LS20AP is a direct electrical and mechanical substitute. The substitution is valid when the cut tape packaging format is acceptable for assembly and procurement workflows.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS3 compliance, REACH unaffected status, EAR99 export classification, and HTSUS coding.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution requires matching of maximum AC volts (175 V), maximum DC volts (225 V), varistor voltage range (243-297 V typical 270 V), surge current capacity (6.5 kA), and energy absorption (90 J).

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tape and reel versus cut tape) does not affect electrical characteristics, performance, or reliability of the varistor component itself.

Q: What is the operating temperature range for both parts?

A: Both V175LS20APX2855 and V175LS20AP operate across -55°C to 85°C ambient temperature range.
