Substitute Part Grouping Explanation

Substitute parts for the MF-SVS230S-0 are identified based on electrical and mechanical parameter equivalence within the Multifuse® MF-SVS series. The substitution criteria are strictly defined by the following parameters:

Voltage rating: 10V maximum
Hold current (Ih): 2.3A maximum
Trip current (It): 5.2A
Initial resistance (Ri): 10 mOhms minimum
Post-trip resistance (R1): 36 mOhms maximum
Operating temperature range: -40°C to 85°C
Package type: Strap configuration
Physical dimensions: 22.00mm L x 5.20mm W x 0.90mm thickness maximum
Polymeric PTC type
Regulatory compliance: cURus and TUV approval

Parts meeting all these parameters are classified as direct substitutes. Variations in product status (active versus obsolete) and packaging designation do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

Both MF-SVS230-0 and MF-SVS230N-0 are electrically and mechanically equivalent to the MF-SVS230S-0. Selection between these substitutes should be based on the following factors:

MF-SVS230-0: This part carries active product status and is available in bulk packaging. It maintains full electrical and mechanical equivalence to the obsolete MF-SVS230S-0 and is suitable for new designs and ongoing production requirements.

MF-SVS230N-0: This part also carries active product status with higher inventory availability (1017 pcs). It provides identical electrical performance and mechanical compatibility. The part number suffix variation does not indicate functional differences within the specified parameters.

Both substitute parts hold cURus and TUV approvals, are ROHS3 compliant, and maintain the same operating temperature range and regulatory compliance profile as the original part. Selection may be determined by inventory availability, packaging preferences, or supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can MF-SVS230-0 or MF-SVS230N-0 be used as direct replacements for MF-SVS230S-0?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including voltage rating, hold current, trip current, resistance characteristics, operating temperature range, physical dimensions, and regulatory approvals are identical.

Q: What is the difference between MF-SVS230-0 and MF-SVS230N-0?

A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The difference in part number suffix does not reflect functional variation. Both are active products with full regulatory compliance.

Q: Why is the original MF-SVS230S-0 listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The availability of active equivalent parts (MF-SVS230-0 and MF-SVS230N-0) ensures continued design support and component availability for applications requiring this electrical specification.

Q: Are there any packaging differences between these parts?

A: All three parts use strap package configuration with identical physical dimensions (22.00mm L x 5.20mm W x 0.90mm thickness). The MF-SVS230-0 is designated as bulk packaging, while MF-SVS230S-0 and MF-SVS230N-0 do not specify packaging designation in the provided data.

Q: Do these parts meet current regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and hold cURus and TUV approvals. Moisture sensitivity level is rated at MSL 1 (Unlimited), indicating no moisture sensitivity constraints for storage or handling.

Q: What is the hold current specification, and why is it important for substitution?

A: The hold current (Ih) is specified at 2.3A maximum for all three parts. This parameter defines the maximum continuous current the fuse can carry without tripping. Equivalence in this parameter is essential for proper circuit protection function.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical performance, mechanical fit, and regulatory compliance are identical across all three parts. No circuit redesign or board layout modification is required when substituting between these parts.
