The substitute part maintains functional equivalence for screw terminal power tap applications while offering alternative termination and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (55556-9): Select the 55556-9 when solder termination is required for PCB assembly processes. This part is suitable for applications where tin-lead contact finish is acceptable and RoHS compliance is not a design requirement.

Substitute Part Selection (5055556-9): Select the 5055556-9 when press-fit termination is preferred for automated assembly operations. This substitute part is ROHS3 compliant and suitable for applications requiring regulatory compliance with modern environmental standards. The press-fit termination method eliminates soldering requirements and provides improved assembly reliability. The 25 A current rating specification provides defined electrical performance parameters for power distribution applications.

Compliance Considerations: The substitute part 5055556-9 provides ROHS3 compliance and defined Moisture Sensitivity Level (MSL 1), making it suitable for applications subject to environmental and regulatory requirements. The main part 55556-9 carries "Not Applicable" status for both RoHS and MSL, indicating it may be subject to different regulatory frameworks or legacy product classifications.

Inventory and Availability: The substitute part 5055556-9 maintains higher inventory levels (2508 pieces) compared to the main part (793 pieces), providing improved supply chain availability for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can 5055556-9 be used as a direct replacement for 55556-9 in existing designs?

A: The 5055556-9 is functionally equivalent for screw terminal power tap applications with matching M4 screw size, 10-pin configuration, and through-hole mounting. However, the termination method differs (press-fit vs. solder), requiring PCB design and assembly process compatibility verification. Designs utilizing solder termination processes must be adapted to accommodate press-fit termination.

Q: What are the key differences between these two part numbers?

A: The primary differences are termination method (solder vs. press-fit), contact finish (tin-lead vs. tin), RoHS compliance status (not applicable vs. ROHS3 compliant), and packaging format (standard vs. box). Both parts maintain identical screw size, pin count, mounting type, and insulation material specifications.

Q: Does the press-fit termination of 5055556-9 affect electrical performance?

A: Both parts are designed for screw terminal power tap applications with identical M4 screw size and 10-pin configuration. The substitute part 5055556-9 specifies a 25 A current rating. The main part 55556-9 does not provide a specified current rating in the available documentation.

Q: Is the copper alloy contact material of 5055556-9 compatible with copper contact specifications?

A: Copper alloy is a copper-based material composition and maintains electrical and mechanical compatibility with applications designed for copper contacts. Both materials provide equivalent conductivity and contact reliability for screw terminal applications.

Q: What packaging considerations apply to these parts?

A: The main part 55556-9 is supplied in standard packaging, while the substitute part 5055556-9 is supplied in box packaging. Packaging format may affect inventory management, handling procedures, and bulk ordering requirements but does not impact functional performance or electrical characteristics.

Q: Which part should be selected for new designs?

A: For new designs, the selection between 55556-9 and 5055556-9 depends on termination method requirements (solder vs. press-fit), regulatory compliance needs (RoHS3 compliance for 5055556-9), and assembly process capabilities. Both parts are active products from TE Connectivity AMP Connectors with confirmed inventory availability.
