Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.7030.39 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Current Rating: 250 mA
Voltage Rating (AC): 125 V
Response Time: Fast Blow
Mounting Type: Through Hole
Package Type: Cartridge, Non-Standard (Axial)
Breaking Capacity: 300 A @ Rated Voltage
Melting I²t: 0.0094
Physical Dimensions: 0.093" Dia × 0.315" L (2.36 mm × 8.00 mm)
Operating Temperature Range: −55°C to +85°C
Series: 172322

Two active alternatives meet these substitution criteria. The first substitute maintains identical AC voltage specifications. The second substitute extends voltage capability to include DC operation while maintaining all other electrical and mechanical parameters.

Engineering Selection Recommendations

SCHURTER 7010.7030.47 is the direct functional equivalent for applications requiring AC-only operation at 125 V. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance with REACH unaffected designation. Approval agencies include CSA, GAM T1, and UR.

SCHURTER 7010.7030.13 is the parametric equivalent for applications requiring dual AC/DC voltage capability at 125 V. This part extends the voltage rating to include 125 V DC operation while maintaining all other electrical characteristics and mechanical dimensions. It carries active product status, ROHS3 compliance, and REACH unaffected designation. Approval agencies include CSA and UR. This part is available in bulk packaging.

Both substitutes are members of the SCHURTER 172322 series and maintain identical breaking capacity, melting I²t, thermal operating range, and physical dimensions as the obsolete 7010.7030.39.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7010.7030.47 be used as a direct replacement for the obsolete 7010.7030.39?

A: Yes. The 7010.7030.47 maintains identical current rating (250 mA), AC voltage rating (125 V), response time (fast blow), mounting configuration (through hole), package type (cartridge, non-standard axial), breaking capacity (300 A), melting I²t (0.0094), physical dimensions (0.093" Dia × 0.315" L), and operating temperature range (−55°C to +85°C). The primary difference is active product status and enhanced compliance certifications.

Q: What is the difference between SCHURTER 7010.7030.47 and 7010.7030.13?

A: Both parts are parametric equivalents with identical AC voltage ratings (125 V) and all electrical/mechanical specifications. The 7010.7030.13 extends capability to include 125 V DC operation, making it suitable for applications requiring dual AC/DC voltage protection. The 7010.7030.13 is available in bulk packaging, while the 7010.7030.47 is available in standard packaging.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions of 0.093" diameter by 0.315" length (2.36 mm × 8.00 mm), ensuring mechanical compatibility in through-hole board mount applications.

Q: What are the approval agencies for each substitute?

A: SCHURTER 7010.7030.47 carries CSA, GAM T1, and UR approvals. SCHURTER 7010.7030.13 carries CSA and UR approvals. Both meet the regulatory requirements of the obsolete 7010.7030.39.

Q: Are the substitute parts RoHS and REACH compliant?

A: Both active substitutes (7010.7030.47 and 7010.7030.13) are ROHS3 compliant and REACH unaffected. The obsolete part's compliance status was not specified.

Q: Which substitute should be selected for new designs?

A: For AC-only applications at 125 V, either substitute is acceptable. For applications requiring DC voltage protection capability, SCHURTER 7010.7030.13 is the appropriate selection. Both parts are active and carry current compliance certifications.
