Substitute Part Grouping Explanation

Substitution of the OTBH105KNPIR 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 - DC: 1500V (1.5kV) (exact match required)
• Voltage Rating - AC: 660V (exact match required)
• Dielectric Material: Paper, Metallized (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)

Mechanical Parameters:

• Package / Case: Radial, Can (exact match required)
• Mounting Type: Chassis Mount, Requires Holder/Bracket (exact match required)
• Termination: Solder Lug (exact match required)
• Lead Spacing: 0.810" (20.57mm) (exact match required)
• Physical Dimensions: 2.160" L x 1.310" W (54.86mm x 33.27mm), Lip; Height - Seated (Max): 2.250" (57.15mm) (exact match required)

Application Compatibility:

• DC Link, DC Filtering; Motor Run (exact match required)

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Packaging format differences (such as bulk versus standard packaging) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The OTBH105KNPIR-F is a direct functional equivalent to the obsolete OTBH105KNPIR. Both components are manufactured by Cornell Dubilier Electronics within the OTB series and satisfy identical electrical and mechanical specifications for 1 µF, 1500V DC film capacitor applications.

Key Differentiation:

The primary distinction between the two parts is product status and regulatory compliance. The OTBH105KNPIR is classified as obsolete, while the OTBH105KNPIR-F maintains active production status. Additionally, the OTBH105KNPIR-F is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance upgrade aligns with current environmental and regulatory requirements for new equipment designs and procurement specifications.

For applications requiring continued supply, new designs, or compliance with RoHS3 mandates, the OTBH105KNPIR-F is the appropriate selection. Both parts are electrically and mechanically interchangeable within DC link, DC filtering, and motor run circuit applications operating within the specified -55°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the OTBH105KNPIR-F be used as a direct replacement for the OTBH105KNPIR?

A: Yes. The OTBH105KNPIR-F is electrically and mechanically equivalent to the OTBH105KNPIR. Both components feature identical capacitance (1 µF), voltage ratings (1500V DC / 660V AC), dielectric material (paper metallized), physical dimensions, lead spacing, and termination type. The components are pin-compatible and functionally interchangeable in all applications.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The OTBH105KNPIR is classified as obsolete, indicating discontinued production and limited future availability. The OTBH105KNPIR-F is active production, ensuring reliable supply for current and future procurement. For new designs or long-term applications, the active part is recommended to avoid supply chain disruption.

Q: Does the RoHS3 compliance difference affect circuit performance?

A: No. RoHS3 compliance is a regulatory and environmental designation reflecting manufacturing process standards and material composition restrictions. It does not alter electrical performance, capacitance value, voltage rating, or operating characteristics. Both parts function identically within specified electrical parameters.

Q: Are the physical dimensions and mounting requirements identical?

A: Yes. Both the OTBH105KNPIR and OTBH105KNPIR-F share identical physical dimensions (2.160" L x 1.310" W, 54.86mm x 33.27mm with lip), maximum seated height (2.250" / 57.15mm), lead spacing (0.810" / 20.57mm), and mounting type (chassis mount requiring holder/bracket). No mechanical modifications are required for substitution.

Q: What is the difference between the standard packaging and bulk packaging designations?

A: The OTBH105KNPIR-F is supplied in bulk packaging format, while the original OTBH105KNPIR uses standard packaging. Bulk packaging typically refers to quantity-based distribution without individual component packaging. This distinction affects procurement and logistics but does not influence component specifications or performance.

Q: Are both parts suitable for DC link and motor run applications?

A: Yes. Both the OTBH105KNPIR and OTBH105KNPIR-F are specified for DC link, DC filtering, and motor run applications. The 1500V DC rating and paper metallized dielectric construction support these high-voltage, high-reliability applications within the -55°C to 85°C operating temperature range.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly. Standard storage conditions are appropriate for both the OTBH105KNPIR and OTBH105KNPIR-F.
