Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity Erni 225721 is determined by the following critical parameters:

Core Compatibility Criteria:

• Number of Pins: 10
• Terminal Type: Screw Terminal, Power Tap
• Mounting Type: Through Hole, Right Angle
• Termination Method: Press-Fit
• Current Rating: Equal to or greater than 100 A

Compliance Requirements:

• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)
• ECCN Classification: EAR99

The substitute part Würth Elektronik 7461064 satisfies all core compatibility criteria and compliance requirements. The substitute component exceeds the current rating specification at 240 A, providing enhanced electrical capacity within the same form factor and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 7461064 is the qualified substitute for the obsolete TE Connectivity Erni 225721. Selection rationale is based on the following factors:

Product Status: The substitute component maintains active product status, ensuring ongoing availability and manufacturer support. The original part's obsolete classification creates supply chain risk that the substitute directly addresses.

Electrical Compatibility: Both components share identical pin count, terminal type, and mounting configuration. The substitute's 240 A current rating exceeds the original 100 A specification, providing design margin and enhanced electrical capacity for the same physical footprint.

Regulatory Compliance: Both components maintain ROHS3 compliance and identical MSL ratings. The substitute carries REACH Affected status compared to the original's REACH Unaffected status; however, this does not preclude substitution and reflects current regulatory classification of the substitute manufacturer's materials.

Mechanical Compatibility: Press-fit termination and through-hole, right-angle mounting are identical across both components, ensuring direct PCB integration without design modification.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 7461064 be used as a direct replacement for the TE Connectivity Erni 225721?

A: Yes. Both components share identical pin count (10), terminal type (screw terminal, power tap), mounting configuration (through-hole, right-angle), and termination method (press-fit). The substitute meets or exceeds all electrical and mechanical parameters required for substitution.

Q: What is the significance of the higher current rating in the substitute part?

A: The Würth Elektronik 7461064 is rated for 240 A compared to the original 100 A specification. This higher rating provides additional electrical capacity and design margin within the same physical package, making it suitable for applications requiring the original component's specifications.

Q: Are there packaging differences between the main part and substitute?

A: The original TE Connectivity Erni 225721 packaging is listed as unspecified. The Würth Elektronik 7461064 is supplied in bulk packaging. Procurement quantities and handling procedures should account for this packaging difference.

Q: Does the REACH Affected status of the substitute affect substitution eligibility?

A: No. The substitute's REACH Affected classification reflects current regulatory status of the manufacturer's materials and does not preclude substitution. Both components maintain compliance with applicable regulatory frameworks for their respective classifications.

Q: Are there any screw or contact material differences?

A: The original component specifies tin contact finish and copper alloy contact material. The substitute component does not provide detailed specifications for contact finish and contact material in the available data. Detailed material specifications should be obtained from the Würth Elektronik datasheet for applications requiring specific contact material properties.

Q: What is the inventory status for these components?

A: The original TE Connectivity Erni 225721 has 784 pieces in stock as new original inventory. The Würth Elektronik 7461064 substitute has 1228 pieces in stock as new original inventory, providing enhanced availability for procurement planning.
