Littelfuse 0216.630VXP Ceramic Fuse 630mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216.630VXP is an active ceramic cartridge fuse rated at 630mA, 250VAC, with fast-blow response characteristics in a 5x20mm form factor. This component requires a dedicated fuse holder for installation. Finding equivalent and substitute parts is necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 0216.630VXP is determined by strict equivalence across the following critical parameters:

Current Rating: 630 mA (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Fuse Type: Cartridge, Ceramic (exact match required)
Response Time: Fast Blow (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Breaking Capacity @ Rated Voltage: 1.5kA (exact match required)
Mounting Type: Requires Holder (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria without exception. Substitutes are grouped by manufacturer: Littelfuse variants (0216.630HXP, 0216.630MXP, 0216.630TXP), SCHURTER direct equivalent (0001.1002), and OptiFuse parametric equivalent (FCD-630MA).

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance status. Selection among equivalents should be based on:

Inventory availability: OptiFuse FCD-630MA offers the highest stock level at 3827 units; SCHURTER 0001.1002 provides 1570 units; Littelfuse variants range from 942 to 1190 units.
Certification alignment: Littelfuse parts carry CCC, CE, CSA, SEMKO, UR, and VDE approvals. SCHURTER 0001.1002 carries CCC, cURus, KC, and VDE approvals. OptiFuse FCD-630MA carries IEC 60127 certification.
Melting I²t characteristics: Littelfuse parts specify 0.175 I²t; SCHURTER 0001.1002 specifies 0.207 I²t; OptiFuse FCD-630MA specifies 0.0672 I²t. These variations reflect internal thermal characteristics but do not affect substitution eligibility given identical current and voltage ratings.
DC Cold Resistance: Littelfuse parts specify 0.465 Ohms; SCHURTER and OptiFuse data do not specify this parameter in the provided input.

Frequently Asked Questions (FAQ)

Q: Can 0216.630HXP, 0216.630MXP, and 0216.630TXP be used interchangeably with 0216.630VXP?

A: Yes. All three Littelfuse variants meet identical electrical and mechanical specifications: 630mA, 250VAC, fast-blow response, 5x20mm package, 1.5kA breaking capacity, and -55°C to 125°C operating range. They are direct parametric equivalents.

Q: Is SCHURTER 0001.1002 a suitable replacement for the Littelfuse 0216.630VXP?

A: Yes. The SCHURTER 0001.1002 meets all critical parameters: 630mA current rating, 250VAC voltage rating, fast-blow response, 5x20mm package, 1.5kA breaking capacity, and identical operating temperature range. It is a direct manufacturer equivalent from a different supplier.

Q: What is the difference between OptiFuse FCD-630MA and the Littelfuse variants?

A: The OptiFuse FCD-630MA is a parametric equivalent meeting all electrical and mechanical requirements. The primary difference is the melting I²t value (0.0672 versus 0.175), which reflects internal thermal design but does not affect substitution eligibility given identical current and voltage ratings. OptiFuse also specifies 250V DC rating in addition to 250V AC.

Q: Do all substitute parts require the same fuse holder?

A: Yes. All substitute parts share the identical 5x20mm form factor and require-holder mounting type. They are mechanically interchangeable in any standard 5x20mm fuse holder.

Q: Are there any compliance or certification differences between substitutes?

A: Certification bodies differ by manufacturer. Littelfuse parts carry CCC, CE, CSA, SEMKO, UR, and VDE approvals. SCHURTER 0001.1002 carries CCC, cURus, KC, and VDE approvals. OptiFuse FCD-630MA carries IEC 60127 certification. All are ROHS3 compliant and REACH unaffected. Selection should align with your application's specific certification requirements.

Q: Which substitute offers the best inventory availability?

A: OptiFuse FCD-630MA provides the highest stock level at 3827 units, followed by SCHURTER 0001.1002 at 1570 units. Littelfuse variants range from 942 to 1190 units.
