Key Parameters

Substitute Part Grouping Explanation

Substitution for the 851-02/001 is determined by the following critical parameters:

• Filter Type & Configuration: Single Phase, Single Stage (mandatory match)
• Voltage Rating: Minimum 250VAC capability (original supports 115V/250VAC)
• Current Rating: Minimum 2A (original rated at 2A; higher ratings acceptable)
• Mounting & Termination: Chassis Mount with Quick Connect (mandatory match)
• Frequency Range: Must support 50/60Hz operation (original specification)
• Compliance: CSA, UR, VDE certifications preferred for regulatory continuity

The substitute parts listed below meet these core substitution criteria while offering active product status and improved availability.

Engineering Selection Recommendations

2VB1 (TE Connectivity Corcom Filters)

The 2VB1 provides direct current and voltage compatibility with the 851-02/001, maintaining the 2A rating and 50/60Hz frequency specification. It retains identical mounting and termination characteristics. This substitute is recommended for applications operating within the -10°C to 40°C temperature range and where 250VAC operation is sufficient. The 2VB1 holds active product status with CSA, UR, and VDE certifications, ensuring regulatory compliance continuity.

FN2010-3-06 (Schaffner EMC Inc.)

The FN2010-3-06 offers enhanced current capacity at 3A and extended frequency range (DC ~ 400Hz), providing operational flexibility beyond the original 50/60Hz specification. Operating temperature range extends to -25°C ~ 100°C, matching the lower temperature limit of the original part while exceeding the upper limit. This substitute is suitable for applications requiring higher current headroom or broader frequency operation. The FN2010-3-06 maintains chassis mount quick connect configuration with CSA, ENEC, and UR certifications.

Both substitutes are ROHS3 compliant and carry active product status with established inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 2VB1 replace the 851-02/001 in all applications?

A: The 2VB1 is compatible for applications operating at 250VAC with 2A current requirements and within the -10°C to 40°C temperature range. If the original application utilized the 115VAC rating or operates outside this temperature window, the 2VB1 may not be suitable.

Q: What is the advantage of the FN2010-3-06 over the 2VB1?

A: The FN2010-3-06 provides 3A current capacity (versus 2A), extended operating temperature range (-25°C ~ 100°C), and broader frequency support (DC ~ 400Hz). These characteristics make it suitable for applications requiring higher current margins or operation beyond standard 50/60Hz frequencies.

Q: Are both substitutes compatible with quick connect termination?

A: Yes. Both the 2VB1 and FN2010-3-06 feature quick connect termination, matching the original 851-02/001 configuration.

Q: Do the substitute parts maintain the same inductance value?

A: No. The 851-02/001 has 1.1mH inductance, the 2VB1 has 539µH, and the FN2010-3-06 has 2.5mH. Inductance differences may affect filtering characteristics in specific circuit applications and should be evaluated against system requirements.

Q: What certifications do the substitute parts carry?

A: The 2VB1 holds CSA, UR, and VDE certifications. The FN2010-3-06 holds CSA, ENEC, and UR certifications. Both maintain regulatory compliance suitable for general-purpose applications.

Q: Are both substitutes ROHS3 compliant?

A: Yes. Both the 2VB1 and FN2010-3-06 are ROHS3 compliant, matching the environmental compliance status of the original 851-02/001.
