Substitute Part Grouping Explanation

Substitution between the main part 640504-4 and the equivalent part 2-640504-4 is based on identical electrical and mechanical parameters. Both parts share the same connector configuration, contact arrangement, pitch specifications, and performance ratings. The substitution logic is determined by the following critical parameters that must remain constant:

• Connector Type: Header
• Number of Positions and Rows: 20 positions in 4 rows
• Pitch Specifications: 0.165" (4.20mm) mating pitch and row spacing
• Mounting Configuration: Through-hole, shrouded 4-wall design
• Electrical Performance: 6A current rating, 250VAC voltage rating
• Temperature Range: -55°C ~ 105°C
• Contact Material and Geometry: Phosphor bronze, circular contact shape
• Termination Method: Solder

Parts meeting these criteria are electrically and mechanically interchangeable for board-level interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

The part 2-640504-4 serves as a direct equivalent to 640504-4 with full electrical and mechanical interchangeability. The primary distinction between these parts is the RoHS compliance status: 640504-4 is not applicable for RoHS classification, while 2-640504-4 is ROHS3 Compliant. This difference reflects manufacturing process updates and material composition changes to meet current regulatory requirements.

For applications requiring ROHS3 compliance or subject to environmental regulations mandating lead-free or restricted substance standards, part 2-640504-4 is the appropriate selection. The contact finish on the post differs slightly (tin versus tin-lead), which aligns with RoHS3 compliance objectives while maintaining identical electrical performance and solder joint reliability.

Both parts maintain identical electrical ratings, temperature performance, and mechanical dimensions. Selection between these parts should be based on regulatory compliance requirements applicable to the end application and geographic market.

Frequently Asked Questions (FAQ)

Q: Are parts 640504-4 and 2-640504-4 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 6A current rating, 250VAC voltage rating, operating temperature range of -55°C to 105°C, and contact material composition. They perform identically in electrical applications.

Q: What is the difference between the contact finishes on the post?

A: Part 640504-4 uses tin-lead finish on the post, while 2-640504-4 uses tin finish. Both finishes provide equivalent solder joint reliability and electrical performance at the specified 150.0µin (3.81µm) thickness. The tin finish on 2-640504-4 aligns with ROHS3 compliance requirements.

Q: Can I use 2-640504-4 as a direct replacement for 640504-4 in existing designs?

A: Yes. The parts are mechanically and electrically identical. No design modifications are required. The 2-640504-4 variant is suitable for direct substitution in all applications where 640504-4 was previously specified.

Q: What does ROHS3 Compliant mean for part 2-640504-4?

A: ROHS3 Compliant indicates that part 2-640504-4 meets the Restriction of Hazardous Substances Directive requirements, which restrict the use of specific hazardous materials including lead. This compliance is relevant for applications in regulated markets or industries with environmental material restrictions.

Q: Are the mechanical dimensions identical between these parts?

A: Yes. Both parts have identical mechanical specifications: 20 positions in 4 rows, 0.165" (4.20mm) pitch and row spacing, 0.220" (5.59mm) mating contact length, 0.210" (5.33mm) post contact length, and 0.531" (13.50mm) insulation height. They are mechanically interchangeable.

Q: What is the through-hole mounting configuration for these connectors?

A: Both parts feature through-hole solder termination with latch lock fastening. The shrouded 4-wall design provides mechanical stability and polarization during board assembly and mating operations.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts are rated for continuous operation across the -55°C to 105°C temperature range. The polyamide nylon insulation material and phosphor bronze contacts maintain performance throughout this operating window.
