Substitute Part Grouping Explanation

Substitution of the SCRN248R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating (AC): 2000Vpk (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)
• Termination: Threaded, Male (exact match required)
• Physical dimensions: 2.160" L × 1.310" W, Height 3.190" (exact match required)
• Lead spacing: 0.810" (exact match required)

Compliance & Status:

• Manufacturer: Cornell Dubilier Electronics (CDE) (same manufacturer preferred for consistency)
• Series: SCR (same series preferred)

The substitute part SCRN248R-F meets all electrical and mechanical equivalence criteria and is manufactured by the same supplier.

Engineering Selection Recommendations

SCRN248R-F is the direct equivalent and substitute for SCRN248R.

Basis for Selection:

1. Electrical Equivalence: The SCRN248R-F maintains identical capacitance (1 µF), tolerance (±10%), voltage rating (2000Vpk AC), dielectric material (paper metallized), and operating temperature range (-40°C to 80°C).

2. Mechanical Compatibility: Physical dimensions, lead spacing, package type (radial can), mounting configuration (chassis mount with holder/bracket), and termination style (threaded male) are identical, ensuring direct mechanical interchangeability.

3. Product Status: The SCRN248R-F is in active production status, whereas the SCRN248R is obsolete. Selection of the SCRN248R-F ensures continued availability and supply chain support.

4. Regulatory Compliance: The SCRN248R-F is ROHS3 compliant, providing improved environmental and regulatory compliance compared to the non-compliant SCRN248R. Both parts maintain REACH Unaffected status and EAR99 ECCN classification.

5. Manufacturer Consistency: Both parts are manufactured by Cornell Dubilier Electronics (CDE) within the SCR series, ensuring design and quality consistency.

Frequently Asked Questions (FAQ)

Q: Can SCRN248R-F be used as a direct replacement for SCRN248R in existing designs?

A: Yes. The SCRN248R-F is electrically and mechanically equivalent to the SCRN248R across all specified parameters, including capacitance, voltage rating, dielectric material, physical dimensions, lead spacing, and termination style. Direct substitution is supported without circuit modification.

Q: What is the primary difference between SCRN248R and SCRN248R-F?

A: The SCRN248R-F is the active production equivalent of the obsolete SCRN248R. The SCRN248R-F offers ROHS3 compliance, whereas the SCRN248R is RoHS non-compliant. Both parts are electrically and mechanically identical.

Q: Are there any packaging differences between these parts?

A: The SCRN248R-F is supplied in bulk packaging, while the SCRN248R packaging specification is not provided. Both parts use identical radial can package types with threaded male termination and require chassis mount holders or brackets.

Q: Does the ROHS3 compliance of SCRN248R-F affect circuit performance?

A: No. ROHS3 compliance is a regulatory and environmental designation that does not alter electrical performance, voltage rating, capacitance value, or operating characteristics. The SCRN248R-F maintains identical electrical specifications to the SCRN248R.

Q: What applications are these capacitors suitable for?

A: Both the SCRN248R and SCRN248R-F are specified for commutation, high frequency switching, and high pulse DV/DT applications. The 2000Vpk AC rating and paper metallized dielectric support these high-voltage, high-frequency switching requirements.

Q: Is the lead spacing identical between SCRN248R and SCRN248R-F?

A: Yes. Both parts have identical lead spacing of 0.810" (20.57mm), ensuring compatibility with existing PCB layouts and mounting hardware.
