Substitute Part Grouping Explanation

Substitution eligibility for the SCRN247R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.5 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating (AC): 2000Vpk (2KVPK) (exact match required)
• Dielectric material: Paper, Metallized (exact match required)
• Operating temperature range: -40°C to 80°C (exact match required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting configuration: Chassis Mount, Requires Holder/Bracket (exact match required)
• Physical dimensions: 2.160" L × 1.310" W (54.86mm × 33.27mm), Lip (exact match required)
• Height (seated, max): 2.690" (68.33mm) (exact match required)
• Termination style: Threaded, Male (exact match required)
• Lead spacing: 0.810" (20.57mm) (exact match required)

Application Compatibility:

• Commutation, High Frequency Switching, High Pulse DV/DT performance requirements (exact match required)

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Product status and compliance certifications are secondary considerations that do not affect functional substitutability but influence procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

The SCRN247R-F is a direct functional equivalent to the SCRN247R. All electrical and mechanical parameters are identical, ensuring pin-for-pin and form-factor compatibility within the same application circuit.

Product Status Consideration: The SCRN247R carries obsolete status, while the SCRN247R-F is active. For new designs or long-term production continuity, the SCRN247R-F is the appropriate selection due to its active product status and ongoing manufacturer support.

Compliance Consideration: The SCRN247R-F is ROHS3 compliant, whereas the SCRN247R is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the SCRN247R-F satisfies compliance obligations. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Inventory and Availability: The SCRN247R-F maintains higher inventory levels (1445 Pcs) compared to the SCRN247R (845 Pcs), supporting improved supply chain reliability for ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can SCRN247R-F replace SCRN247R in existing designs?

A: Yes. The SCRN247R-F is electrically and mechanically identical to the SCRN247R. All electrical parameters (capacitance, voltage rating, tolerance, dielectric material, temperature range) and mechanical parameters (dimensions, termination, lead spacing, mounting configuration) are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between SCRN247R and SCRN247R-F?

A: The primary differences are product status and compliance certification. The SCRN247R is obsolete and RoHS non-compliant. The SCRN247R-F is active and ROHS3 compliant. Functionally and mechanically, both parts are identical.

Q: Are there any packaging differences between these parts?

A: The SCRN247R is supplied in standard packaging, while the SCRN247R-F is supplied in bulk packaging. Both maintain identical physical dimensions, termination style, and mounting requirements. Packaging format does not affect electrical or mechanical performance.

Q: Which part should be selected for new production?

A: The SCRN247R-F is recommended for new production due to its active product status, ROHS3 compliance, and higher inventory availability. The SCRN247R should be reserved for legacy system maintenance where existing stock is available.

Q: Are both parts suitable for high-frequency switching and high-pulse DV/DT applications?

A: Yes. Both the SCRN247R and SCRN247R-F are rated for commutation, high-frequency switching, and high-pulse DV/DT applications. Application performance is identical between the two parts.

Q: What is the lead spacing for these capacitors?

A: Both parts feature 0.810" (20.57mm) lead spacing with threaded male termination, supporting standard chassis-mount holder/bracket configurations.
