Substitute Part Grouping Explanation

Substitution for the V07E460 is based on strict electrical and mechanical parameter matching within the Littelfuse UltraMOV™ series. All substitute parts maintain identical specifications across the following critical parameters:

Varistor voltage range: 675V (Min) to 825V (Max), with 750V typical
Surge current rating: 1.75 kA
Energy absorption: 48 J
AC/DC voltage ratings: 460V AC / 615V DC
Physical form factor: Disc 7mm through-hole package
Thermal operating range: -55°C to 85°C
Capacitance characteristics: 45 pF @ 1 MHz

The substitute parts differ only in packaging configuration (bulk vs. tape) and product status (active vs. obsolete), with no impact on electrical performance or mechanical compatibility.

Engineering Selection Recommendations

All three substitute parts (V07E460P, V07P460PL1B5, V07P460PX2855) are direct functional equivalents to the obsolete V07E460. Selection among active alternatives should be based on the following criteria:

V07E460P is the primary direct replacement, maintaining identical part number structure with bulk packaging. This part carries active product status and full REACH compliance certification.

V07P460PL1B5 and V07P460PX2855 are parametric equivalents within the UltraMOV™ series, offering identical electrical and mechanical performance. Both parts are active and REACH compliant, with bulk packaging suitable for production environments.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage conditions. Selection may be based on supplier availability, packaging preferences, or inventory management requirements, as electrical performance is identical across all options.

Frequently Asked Questions (FAQ)

Q: Can V07E460P be used as a direct replacement for V07E460? A: Yes. V07E460P is electrically and mechanically identical to V07E460, with the primary difference being active product status and bulk packaging. All electrical parameters, physical dimensions, and performance characteristics are equivalent.

Q: What is the difference between V07E460P and V07P460PL1B5? A: Both parts are parametric equivalents with identical electrical specifications and disc 7mm through-hole packaging. The difference lies in part number designation within the UltraMOV™ series. Both are active products with equivalent availability and compliance certifications.

Q: Are all substitute parts RoHS compliant? A: Yes. V07E460P, V07P460PL1B5, and V07P460PX2855 are all ROHS3 compliant, matching the compliance status of the original V07E460.

Q: Can these varistors be used in both AC and DC applications? A: Yes. All parts are rated for maximum AC voltage of 460V and maximum DC voltage of 615V, supporting both application types within these voltage limits.

Q: Does packaging type affect electrical performance? A: No. Bulk packaging is a logistics consideration only. All substitute parts maintain identical electrical characteristics regardless of packaging configuration.

Q: What is the operating temperature range for these varistors? A: All parts operate within -55°C to 85°C ambient temperature range, suitable for industrial and commercial applications.
