Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A50221607 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Terminal block type: Barrier block configuration
• Number of circuits: 16-position
• Pitch spacing: 0.250" (6.35mm)
• Current rating: 10A minimum
• Voltage rating: 300V minimum
• Barrier construction: 2 Wall (Dual) barrier
• Flammability rating: UL94 V-0

Allowable Variations:

• Wire gauge range: 16-30 AWG (substitute may accept wider range than original 18-30 AWG)
• Operating temperature: Substitute may exceed -40°C ~ 105°C upper limit
• Bottom termination: PC pin or quick connect configurations
• Mounting type: Through hole, chassis, or panel mounting
• Insulation material: Thermoplastic or polyamide variants
• Product status: Active status preferred for obsolete parts

The Eaton A00221607 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

For A50221607 Replacement:

The Eaton A00221607 serves as the active-status equivalent for the obsolete A50221607. Both components maintain identical electrical specifications (10A, 300V, 16-circuit, 0.250" pitch) and mechanical configuration (dual-wall barrier block, UL94 V-0 flammability rating).

Key Considerations:

1. Bottom Termination Difference: The A50221607 uses PC pin termination, while the A00221607 provides quick connect (0.250") insulated termination. PCB layout and connector interface compatibility must be verified before substitution.

2. Top Termination Configuration: The A50221607 includes a captive plate assembly with screws. The A00221607 provides screw termination with flange mounting. Mechanical mounting interface requirements determine suitability.

3. Wire Gauge Acceptance: The A00221607 accepts 16-30 AWG wire, providing broader compatibility than the A50221607 specification of 18-30 AWG.

4. Operating Temperature: The A00221607 extends the upper operating limit to 120°C, exceeding the A50221607 specification of 105°C.

5. Compliance Status: Both components carry RoHS non-compliant designation and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the A00221607 directly replace the A50221607 in existing designs?

A: Direct replacement requires verification of bottom termination compatibility. The A50221607 PC pin configuration differs from the A00221607 quick connect termination. PCB footprint and connector interface must accommodate the quick connect design.

Q: What is the significance of the captive plate in the A50221607?

A: The captive plate assembly in the A50221607 provides integrated screw retention during wire termination. The A00221607 screw termination without captive plate requires alternative fastening methods. Mechanical assembly procedures differ between these configurations.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components maintain 10A current rating, 300V voltage rating, 16-circuit configuration, and 0.250" pitch spacing. Electrical performance is equivalent.

Q: Does the A00221607 support the same wire gauge range?

A: The A00221607 accepts 16-30 AWG wire, which encompasses the A50221607 specification of 18-30 AWG. The substitute provides broader wire gauge compatibility.

Q: What mounting differences exist between these connectors?

A: The A50221607 uses through-hole mounting. The A00221607 supports chassis and panel mounting configurations with flange design. Mounting interface requirements determine substitution feasibility.

Q: Are both components RoHS compliant?

A: No. Both the A50221607 and A00221607 carry RoHS non-compliant status. Environmental compliance requirements must be addressed through alternative component selection if RoHS compliance is mandatory.

Q: What is the inventory status for these parts?

A: The A50221607 (obsolete) has 1167 pieces in stock. The A00221607 (active) has 888 pieces in stock. Active-status availability supports long-term supply chain planning.
