TE Connectivity 645169-4 Card Edge Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 645169-4 is a 98-position female card edge connector from the Standard Edge II series, designed for through-hole solder termination applications. This connector features a special 18/31 dual combo configuration with 0.100" (2.54mm) pitch spacing and operates across the temperature range of -55°C to 85°C. The connector accommodates card thicknesses between 0.054" and 0.070" (1.37mm to 1.78mm) and utilizes phosphor bronze contacts with gold plating. Identification of equivalent and substitute parts is necessary to address inventory availability, compliance requirements, and packaging specifications for production and replacement applications.

Substitute Part Grouping Explanation

Substitution between the main part 645169-4 and the equivalent part 5645169-4 is based on electrical and mechanical compatibility. Both connectors maintain identical specifications across all critical parameters that determine functional interchangeability:

Key Parameters for Substitution Compatibility:

• 98-position configuration with special 18/31 dual combo card type
• 0.100" (2.54mm) pitch spacing
• Card thickness accommodation of 0.054" to 0.070" (1.37mm to 1.78mm)
• Dual read-out configuration with 2-row layout
• Phosphor bronze contacts with gold finish (30.0µin thickness)
• Through-hole solder termination
• Operating temperature range of -55°C to 85°C
• Polyester glass-filled insulation material
• Black color and female gender configuration

The primary distinction between these parts lies in packaging format and regulatory compliance status, not in electrical or mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Selection between 645169-4 and 5645169-4 should be determined by regulatory compliance requirements and packaging specifications for the intended application.

645169-4 (Main Part): This configuration is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present regulatory constraints. Standard packaging is appropriate for applications requiring individual unit handling or smaller quantity orders.

5645169-4 (Substitute): This configuration is required for applications subject to ROHS3 compliance mandates and REACH regulatory frameworks. Bulk packaging is appropriate for high-volume production runs and applications where packaging efficiency is a primary consideration. The REACH Unaffected status indicates compliance with European chemical regulations.

Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability within the same circuit design and PCB layout. Selection between these parts is driven by regulatory environment and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are 645169-4 and 5645169-4 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including 98-position configuration, 0.100" pitch, phosphor bronze gold-plated contacts, and operating temperature range of -55°C to 85°C. They function identically in circuit applications.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format and regulatory compliance status. The 645169-4 uses standard packaging and is RoHS non-compliant with REACH-affected status. The 5645169-4 uses bulk packaging and is ROHS3 compliant with REACH Unaffected status. All mechanical and electrical parameters are identical.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements applicable to your market and application. If ROHS3 compliance is required, use 5645169-4. If RoHS compliance is not a constraint, either part is functionally suitable. Consult your regulatory and compliance requirements before final selection.

Q: Can I use 5645169-4 as a direct replacement for 645169-4 in existing assemblies?

A: Yes. The 5645169-4 is mechanically and electrically compatible with 645169-4. The connector will function identically in the same PCB layout and circuit design. Bulk packaging does not affect connector performance.

Q: What does bulk packaging mean for the 5645169-4?

A: Bulk packaging indicates the connector is supplied in larger quantities without individual packaging per unit. This format is standard for high-volume production orders and reduces packaging material costs. The connector itself is identical to standard-packaged versions.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both connectors operate across the identical temperature range of -55°C to 85°C and utilize the same insulation material (polyester, glass filled). Environmental performance characteristics are equivalent.

Q: What does ROHS3 compliance mean?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the connector meets European Union restrictions on hazardous substances. The 5645169-4 meets these requirements; the 645169-4 does not. Applications destined for EU markets typically require ROHS3-compliant components.

Q: What does REACH Unaffected status indicate?

A: REACH Unaffected status indicates the connector does not contain substances of very high concern (SVHC) listed under the European REACH regulation. The 5645169-4 carries this status, while the 645169-4 is REACH Affected. This distinction is relevant for applications subject to European chemical regulations.
