TE Connectivity 530843-4 Card Edge Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 530843-4 is a 44-position female card edge connector designed for Multibus I applications. This connector operates at 0.100" (2.54mm) pitch with dual-row configuration and gold-plated phosphor bronze contacts. The part is classified as Active product status and is currently in stock with 704 units available.

Card edge connectors serve as interface components for printed circuit board edge connections in industrial and computing applications. Substitute parts become necessary when the primary part experiences supply constraints, when design requirements shift between Multibus I and non-specified dual-edge configurations, or when compliance certifications must be updated to meet current regulatory standards.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 530843-4 is determined by the following critical parameters: connector gender (Female), pitch (0.100"), number of rows (2), card thickness tolerance (0.054" ~ 0.070"), mounting type (Through Hole), termination method (Solder), contact finish (Gold), and operating temperature range compatibility.

The substitute parts identified fall into two substitution categories:

Category 1: Direct Position and Configuration Match Parts 5530843-4 and 395-044-520-201 maintain the 44-position configuration with identical pitch, row count, card thickness tolerance, and mounting specifications. These parts are fully interchangeable from a mechanical and electrical standpoint.

Category 2: Position Variance Part 5-5530843-4 operates at 40 positions instead of 44, representing a reduced-capacity alternative. This part shares all other critical parameters including pitch, row configuration, card thickness, and termination method, but is suitable only for applications where 40 positions satisfy functional requirements.

Engineering Selection Recommendations

For Direct Replacement (44-Position Requirement)

Part 5530843-4 (TE Connectivity) is the primary substitute when 44-position configuration is mandatory. This part maintains identical mechanical and electrical specifications to the 530843-4 while offering improved compliance status: ROHS3 Compliant and REACH Unaffected certification. Inventory availability is 1002 units.

Part 395-044-520-201 (Mercury United Electronics) is an alternative 44-position substitute with extended operating temperature range (-40°C ~ 105°C) compared to the original part (-55°C ~ 85°C). This part carries ROHS3 Compliant and REACH Unaffected certifications. Contact finish thickness is reduced to 10.0µin (0.25µm) versus the original 30.0µin (0.76µm). Inventory availability is 768 units.

For Reduced-Capacity Applications (40-Position Requirement)

Part 5-5530843-4 (TE Connectivity) serves applications where 40-position configuration is acceptable. This part offers the highest inventory availability at 2601 units and carries RoHS Compliant certification. All mechanical parameters align with the original part specification.

Compliance Considerations

The original 530843-4 is RoHS non-compliant with vendor-undefined REACH status. All three substitute parts carry current compliance certifications (RoHS3 Compliant or RoHS Compliant with REACH Unaffected status), making them suitable for applications subject to modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can part 5-5530843-4 (40-position) be used in place of 530843-4 (44-position)?

A: Part 5-5530843-4 is mechanically and electrically compatible only if the application circuit design requires 40 positions or fewer. The connector will physically mate with the same card edge thickness and pitch, but only 40 contact positions will be available for signal routing. Applications requiring all 44 positions cannot use this substitute.

Q: What is the difference between 5530843-4 and 395-044-520-201?

A: Both parts maintain 44-position configuration and identical pitch/row specifications. Key differences include: contact material (Phosphor Bronze versus Copper Alloy), contact finish thickness (30.0µin versus 10.0µin), operating temperature range (-55°C ~ 85°C versus -40°C ~ 105°C), and insulation material (Polyester Glass Filled versus Polyester Thermoplastic). Part 395-044-520-201 supports higher maximum operating temperature.

Q: Are all substitute parts RoHS compliant?

A: Yes. Part 5530843-4 is ROHS3 Compliant. Part 5-5530843-4 is RoHS Compliant. Part 395-044-520-201 is ROHS3 Compliant. The original 530843-4 is RoHS non-compliant. Designs requiring RoHS compliance must transition to one of the three substitute parts.

Q: What is the significance of contact finish thickness differences?

A: Contact finish thickness affects wear resistance and contact durability. The original 530843-4 and substitute parts 5530843-4 and 5-5530843-4 specify 30.0µin (0.76µm) gold plating. Part 395-044-520-201 specifies 10.0µin (0.25µm) gold plating. Thicker plating provides extended contact life in high-cycle mating applications.

Q: Can the 530843-4 be used interchangeably with 5530843-4 in existing designs?

A: Yes. Part 5530843-4 maintains identical mechanical dimensions, pitch, row configuration, card thickness tolerance, and electrical specifications. The parts are pin-compatible and functionally equivalent. The primary advantage of 5530843-4 is improved compliance certification status.

Q: What packaging format is available for these parts?

A: The original 530843-4 is available in unspecified packaging. Substitute parts 5530843-4, 5-5530843-4, and 395-044-520-201 are all available in Bulk packaging format.

Q: Are there temperature range limitations when substituting parts?

A: The original 530843-4 operates from -55°C to 85°C. Substitute parts 5530843-4 and 5-5530843-4 maintain this identical range. Part 395-044-520-201 extends the upper limit to 105°C and raises the lower limit to -40°C. Applications operating below -40°C must use the original 530843-4 or parts 5530843-4 and 5-5530843-4.
