• Connector style: Blade Power
• Number of positions: 3
• Mounting configuration: Board Edge, Through Hole, Right Angle
• Termination method: Press-Fit
• Contact layout: 3 Power
• Material flammability rating: UL94 V-0
• Color: Gray
• Moisture sensitivity level: 1 (Unlimited)

Compliance Enhancement: The substitute part 5223971-1 provides improved regulatory compliance status (ROHS3 Compliant versus RoHS non-compliant) while maintaining identical mechanical and electrical interface specifications. Both parts share the same base product number family (223971 versus 5223971) and ECCN/HTSUS classifications, confirming design lineage and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5223971-1 is the direct active equivalent for the obsolete 223971-1. Selection of the substitute is based on the following engineering criteria:

Product Status Alignment: The 5223971-1 maintains active production status, ensuring long-term availability and supply chain continuity. The original 223971-1 is classified as obsolete, creating risk for future procurement and field service requirements.

Regulatory Compliance: The 5223971-1 achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. This compliance status is essential for applications subject to EU RoHS Directive requirements and equivalent international regulations. The original part's RoHS non-compliant status restricts its use in regulated markets.

Mechanical and Electrical Interface Compatibility: Both parts maintain identical connector type, style, position count, mounting configuration, and termination method. The board edge, through-hole, right-angle mounting and press-fit termination ensure direct mechanical compatibility with existing PCB designs and assembly processes.

Certification and Safety Standards: Both parts carry UL94 V-0 flammability rating and identical ECCN/HTSUS classifications, confirming equivalent safety and export compliance profiles.

Contact Finish Enhancement: The substitute part offers Gold or Gold-Palladium contact finish options, providing equivalent or superior electrical performance compared to the gold finish of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 5223971-1 be used as a direct replacement for the 223971-1 in existing designs?

A: Yes. The 5223971-1 is mechanically and electrically compatible with the 223971-1. Both parts share identical connector type, position count, mounting configuration, and press-fit termination. No PCB redesign or assembly process modification is required.

Q: What is the primary advantage of switching to the 5223971-1?

A: The 5223971-1 is an active product with ROHS3 compliance, whereas the 223971-1 is obsolete and RoHS non-compliant. This ensures regulatory compliance, long-term availability, and eliminates supply chain risk.

Q: Are there differences in the contact finish between these parts?
