Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.7050.49 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Current Rating: 500 mA (exact match required)
• Voltage Rating - AC: 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm) (exact match required)
• Breaking Capacity @ Rated Voltage: 300 A (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)

Secondary Consideration:

• Product Status: Active status preferred for long-term availability

Substitute parts meeting all primary criteria are classified as direct equivalents. Parts with additional voltage ratings (AC/DC dual-rated) are classified as parametric equivalents, as they provide expanded application capability while maintaining all specified AC parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Preferred Selection:

SCHURTER 7010.7050.47 is the primary substitute for the obsolete 7010.7050.49. This part maintains identical electrical and mechanical specifications, including current rating, voltage rating, response time, package dimensions, and breaking capacity. The 7010.7050.47 is active in production status and carries ROHS3 compliance certification, supporting long-term procurement and regulatory requirements.

Parametric Equivalents - Alternative Selection:

SCHURTER 7010.7050.13 and 7010.6340.13 are parametric equivalents that satisfy all primary substitution criteria for AC applications. Both parts are active in production status and ROHS3 compliant. The 7010.7050.13 maintains the same series designation (172322) and melting I²t value (0.07) as the main part, with the addition of 125 V DC rating capability. The 7010.6340.13 operates in series 172321 with a melting I²t value of 0.1, providing dual AC/DC voltage rating at 125 V.

Compliance Considerations:

The 7010.7050.47 retains the full approval agency certification (CSA, GAM T1, UR) matching the original part. The 7010.7050.13 carries CSA and UR certifications. The 7010.6340.13 does not specify approval agency certifications. Selection should account for application-specific regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7010.7050.47 be used as a direct replacement for 7010.7050.49?

A: Yes. The 7010.7050.47 is electrically and mechanically identical to the 7010.7050.49 across all specified parameters: 500 mA current rating, 125 V AC voltage rating, fast blow response, through-hole mounting, axial cartridge package, 300 A breaking capacity, and 0.093" Dia x 0.315" L dimensions. The primary difference is product status; 7010.7050.47 is active while 7010.7050.49 is obsolete.

Q: What is the difference between the similar substitute and parametric equivalents?

A: The 7010.7050.47 (similar substitute) matches all specifications of the main part exactly. The parametric equivalents (7010.7050.13 and 7010.6340.13) add 125 V DC voltage rating capability while maintaining all AC specifications. Both parametric equivalents are suitable for applications requiring AC protection; the DC rating provides additional flexibility for dual-voltage applications.

Q: Are there differences in melting I²t values among the substitutes?

A: Yes. The main part 7010.7050.49 and substitute 7010.7050.47 both have a melting I²t of 0.07. The parametric equivalent 7010.7050.13 also has a melting I²t of 0.07. The parametric equivalent 7010.6340.13 has a melting I²t of 0.1. Applications with specific thermal response requirements should account for this difference.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts maintain the identical package dimensions of 0.093" Dia x 0.315" L (2.36mm x 8.00mm), ensuring mechanical compatibility with existing board layouts and through-hole mounting positions.

Q: What are the approval agency certifications for each substitute?

A: The 7010.7050.47 carries CSA, GAM T1, and UR certifications, matching the original part. The 7010.7050.13 carries CSA and UR certifications. The 7010.6340.13 does not specify approval agency certifications. Applications requiring specific regulatory approvals should verify certification requirements against the selected substitute.

Q: Are all substitute parts RoHS compliant?

A: The 7010.7050.47, 7010.7050.13, and 7010.6340.13 are all ROHS3 compliant. The original part 7010.7050.49 does not specify RoHS status.

Q: What is the operating temperature range for all parts?

A: All parts, including the main part and all substitutes, operate across the temperature range of -55°C to 85°C.
