Key Parameters

Substitute Part Grouping Explanation

Substitution for the V14P550P is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (Min/Typ/Max): 819 V / 910 V / 1.001 kV
• Surge current capacity: 6 kA
• Maximum AC and DC voltage ratings: 550 V AC / 745 V DC
• Energy absorption: 190 J
• Mounting configuration: Through Hole
• Package form factor: Disc 14mm
• Number of circuits: 1 Circuit
• Operating temperature range: -55°C to 85°C
• Compliance certifications: ROHS3, REACH Unaffected

The V14E550P meets all these parameters identically and is classified as a parametric equivalent. Additional cross-references (MOVHE14V550Y, ERZ-V14D911) are noted in the substitute list but require independent verification of electrical and mechanical compatibility against the specified parameters.

Engineering Selection Recommendations

The V14E550P is a direct parametric equivalent to the V14P550P. Both components are manufactured by Littelfuse Inc. within the UltraMOV™ series and maintain identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these two parts may be based on inventory availability (V14E550P: 1334 Pcs; V14P550P: 756 Pcs) and procurement lead times, as no technical differentiation exists between them.

Both parts are Active status products with ROHS3 compliance and REACH Unaffected designation, confirming suitability for applications requiring environmental regulatory adherence. The identical operating temperature range (-55°C to 85°C), moisture sensitivity level (MSL 1), and ECCN/HTSUS classifications support interchangeability in circuit design and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can V14E550P be used as a direct replacement for V14P550P?

A: Yes. The V14E550P is a parametric equivalent with identical varistor voltage (910 V typical), surge current rating (6 kA), energy absorption (190 J), and all electrical and mechanical specifications. Both are UltraMOV™ series components in Disc 14mm through-hole packaging.

Q: Are there differences in compliance or certifications between these parts?

A: No. Both V14P550P and V14E550P carry identical ROHS3 compliance, REACH Unaffected status, MSL 1 rating, and ECCN/HTSUS classifications.

Q: What determines substitutability for this varistor?

A: Substitutability is determined by matching varistor voltage rating (819–1.001 kV range), surge current capacity (6 kA), maximum voltage ratings (550 V AC / 745 V DC), energy absorption (190 J), through-hole mounting configuration, Disc 14mm package form factor, and operating temperature range (-55°C to 85°C).

Q: Can parts with different package sizes substitute for the V14P550P?

A: No. The Disc 14mm package form factor is a critical mechanical parameter. Substitutes must maintain identical through-hole mounting and package dimensions to ensure PCB compatibility and circuit board layout integrity.

Q: What is the significance of the 180 pF capacitance specification?

A: The capacitance at 1 MHz (180 pF) is an electrical characteristic of the varistor that affects high-frequency circuit behavior. Substitute parts must maintain this specification to ensure equivalent performance in frequency-dependent applications.
