Littelfuse 0229002.H Glass Cartridge Fuse 2A 250VAC Equivalent & Substitute Parts

Part Overview

The Littelfuse 0229002.H is a 2 A, 250 V AC glass cartridge fuse in the 2AG form factor (5mm x 15mm). This component is classified as obsolete, requiring identification of active equivalent alternatives for new designs and ongoing production support. Substitute parts maintain identical electrical ratings and mechanical form factors while offering improved compliance status and expanded voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0229002.H are grouped based on the following substitution criteria:

Electrical Parameters (Must Match):

• Current Rating: 2 A
• Voltage Rating (AC): 250 V
• Response Time: Slow Blow
• Melting I²t: 30

Mechanical Parameters (Must Match):

• Fuse Type: Cartridge, Glass
• Package / Case: 2AG, 5mm x 15mm
• Mounting Type: Requires Holder

Enhanced Parameters (Allowed Variations):

• Voltage Rating (DC): 125 V (added in substitutes; not present in main part)
• Breaking Capacity: Varies between 35A AC / 10kA DC and 100A AC / 10kA DC
• Compliance: RoHS3 Compliant (substitutes) vs. RoHS non-compliant (main part)

All substitute parts are manufactured by Littelfuse Inc. within the 229 series and maintain identical physical dimensions and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active components manufactured by Littelfuse Inc. and maintain full electrical and mechanical compatibility with the 0229002.H. Selection among substitutes depends on application-specific requirements:

For AC-only applications with 100A breaking capacity requirement: Select 0229002.VXP or 0229002.VXSP. These parts provide the highest breaking capacity specification matching the original part's 100A AC rating.

For applications requiring DC voltage capability: All substitute parts (0229002.HXP, 0229002.HXSP, 0229002.MXP, 0229002.MXSP, 0229002.VXP, 0229002.VXSP) include 125 V DC rating, extending operational scope beyond the original part.

For RoHS3 compliance: All substitute parts are RoHS3 compliant, addressing regulatory requirements not met by the obsolete 0229002.H.

For expanded certification coverage: All substitute parts include CE and PSE approvals in addition to CSA and UL certifications present in the original part.

For inventory availability: 0229002.MXP offers the highest stock level (2329 pcs), followed by 0229002.HXP (1797 pcs) and 0229002.VXSP (1162 pcs).

Frequently Asked Questions (FAQ)

Q: Can 0229002.HXP, 0229002.HXSP, 0229002.MXP, 0229002.MXSP, 0229002.VXP, or 0229002.VXSP be used as direct replacements for 0229002.H?

A: Yes. All substitute parts maintain identical current rating (2 A), AC voltage rating (250 V), response time (Slow Blow), package form factor (2AG, 5mm x 15mm), and melting I²t (30). Physical dimensions and thermal characteristics are identical. The substitutes are mechanically and electrically interchangeable in applications designed for the 0229002.H.

Q: What is the difference between the substitute parts?

A: The primary differences are breaking capacity and packaging designation. Parts designated with "V" (0229002.VXP, 0229002.VXSP) provide 100A AC breaking capacity, matching the original part. Parts designated with "H" or "M" (0229002.HXP, 0229002.HXSP, 0229002.MXP, 0229002.MXSP) provide 35A AC breaking capacity. Parts with "SP" suffix indicate special packaging. All other electrical and mechanical parameters are identical across all substitutes.

Q: Does the addition of 125 V DC rating in substitute parts affect AC-only applications?

A: No. The 125 V DC rating is an additional capability that does not affect AC operation. Applications using only 250 V AC will function identically with either the original part or any substitute part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (0229002.HXP, 0229002.HXSP, 0229002.MXP, 0229002.MXSP, 0229002.VXP, 0229002.VXSP) are RoHS3 compliant. The original 0229002.H is RoHS non-compliant.

Q: What certifications do the substitute parts carry?

A: All substitute parts carry CE, CSA, PSE, and UL approvals. The original part carries CSA, METI, and UL approvals. Substitute parts provide expanded certification coverage suitable for broader market applications.

Q: Can I mix different substitute part numbers in the same circuit or equipment?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably. However, for consistency in maintenance and inventory management, using a single part number across an application is recommended.

Q: What is the DC cold resistance specification, and does it vary among parts?

A: DC cold resistance is 0.0692 Ohms for the original 0229002.H and 0.0698 Ohms for all substitute parts. This minimal variation (0.0006 Ohms) is within normal manufacturing tolerance and does not affect circuit performance.
