Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB50221607 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier block configuration
• Number of circuits: 16 circuits
• Pitch spacing: 0.250" (6.35mm)
• Current rating: 10A minimum
• Voltage rating: 300V minimum
• Top termination: Screws with captive plate
• Bottom termination: PC pin
• Barrier type: 3 wall (tri) barrier
• Mounting type: Through hole
• Flammability rating: UL94 V-0

Allowable Variations:

• Wire gauge range: Substitutes must accommodate the main part's wire gauge specification or broader ranges
• Operating temperature: Substitutes may exceed the main part's temperature range
• Insulation material: Different thermoplastic or polyamide formulations acceptable if flammability rating maintained
• Product status: Active status preferred for obsolete parts
• Compliance certifications: RoHS and REACH status may differ

The identified substitutes CB00221607 and 3PCV-16-006 meet all mandatory matching parameters and are therefore qualified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

CB00221607 (Eaton - Electronics Division)

The CB00221607 is an active product within the Eaton Magnum® CB0 series and represents the direct successor to the obsolete CB50221607. Both parts share identical electrical specifications: 16 circuits, 0.250" pitch, 10A current rating, and 300V voltage rating. The CB00221607 accommodates a broader wire gauge range (16-30 AWG versus 18-30 AWG) and provides enhanced operating temperature capability (-40°C to 120°C versus -40°C to 105°C). The insulation material differs (polyamide versus thermoplastic), but both maintain UL94 V-0 flammability certification. The CB00221607 is non-RoHS compliant. This part is recommended as the primary replacement for the obsolete CB50221607 due to active product status and manufacturer continuity within the same organization.

3PCV-16-006 (TE Connectivity AMP Connectors)

The 3PCV-16-006 is an active product from TE Connectivity's #3 Buchanan series and meets all mandatory electrical and mechanical parameters of the CB50221607. This part provides 16 circuits at 0.250" pitch with 10A current rating and 300V voltage rating. The wire gauge specification (18-22 AWG) is narrower than the main part but overlaps the primary range. Operating temperature extends to 120°C. The 3PCV-16-006 is RoHS3 compliant and carries MSL 1 rating. This part is recommended as an alternative substitute when cross-manufacturer sourcing is acceptable and RoHS compliance is required.

Frequently Asked Questions (FAQ)

Q: Can CB00221607 be used as a direct replacement for CB50221607?

A: Yes. Both parts are 16-circuit barrier blocks with 0.250" pitch, 10A current rating, 300V voltage rating, and identical termination configurations. The CB00221607 is the active product successor and provides equivalent or superior electrical performance. Wire gauge accommodation is broader in the CB00221607 (16-30 AWG). Operating temperature range is extended to 120°C. Both maintain UL94 V-0 flammability certification.

Q: What are the wire gauge compatibility differences between the three parts?

A: The CB50221607 accepts 18-30 AWG wire. The CB00221607 accepts 16-30 AWG wire, providing broader accommodation. The 3PCV-16-006 accepts 18-22 AWG wire, which is narrower. For applications using wire gauges outside the 18-22 AWG range, the 3PCV-16-006 may not be suitable. The CB00221607 accommodates the widest range.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. The CB50221607 and CB00221607 are RoHS non-compliant. The 3PCV-16-006 is RoHS3 compliant. For applications requiring RoHS compliance, the 3PCV-16-006 is the appropriate selection.

Q: Do operating temperature ranges affect substitution eligibility?

A: The CB50221607 operates from -40°C to 105°C. Both substitutes extend this range to 120°C. For applications operating within the original -40°C to 105°C range, both substitutes are suitable. For applications requiring operation above 105°C, both substitutes provide additional thermal margin.

Q: What is the difference between Magnum® CB5000 and Magnum® CB0 series?

A: The CB50221607 belongs to the Magnum® CB5000 series (obsolete), while the CB00221607 belongs to the Magnum® CB0 series (active). Both are Eaton barrier block products with identical circuit configurations and electrical ratings. The CB0 series represents the current product line.

Q: Can 3PCV-16-006 be used in applications originally designed for CB50221607?

A: Yes, provided wire gauge requirements fall within 18-22 AWG. The 3PCV-16-006 meets all mandatory electrical and mechanical parameters. Verify wire gauge compatibility before selection. The 3PCV-16-006 is suitable for new designs and retrofit applications where RoHS compliance is required.

Q: What packaging options are available?

A: The CB50221607 is supplied in standard packaging. The CB00221607 is supplied in bulk packaging. The 3PCV-16-006 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.
