Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 5-530843-4 is determined by strict alignment of core electrical and mechanical parameters. All substitute parts must maintain the following critical specifications: 40-position configuration, 0.100" (2.54mm) pitch, dual-row arrangement, female gender, through-hole mounting, solder termination, gold contact finish, and black color. Card thickness accommodation of 0.054" to 0.070" is a mandatory mechanical requirement for physical compatibility.

The identified substitute parts—TE Connectivity 5-5530843-4 and Mercury United Electronics 395-040-520-201—satisfy these core parameters. Variations in contact material composition, contact finish thickness, operating temperature range, insulation material, and compliance certifications do not preclude substitution when the primary part is unavailable, provided the application requirements fall within the substitute part's specified operating envelope.

Engineering Selection Recommendations

TE Connectivity 5-5530843-4 is the primary substitute for the 5-530843-4. Both parts are manufactured by TE Connectivity AMP Connectors within the Standard Edge II series and maintain identical electrical and mechanical specifications. The 5-5530843-4 achieves RoHS Compliance status, whereas the original part is RoHS non-compliant. This substitute is appropriate for applications requiring RoHS-compliant components while maintaining full functional equivalence. Operating temperature range remains -55°C to 85°C, and contact finish thickness is identical at 30.0µin (0.76µm).

Mercury United Electronics 395-040-520-201 serves as an alternative substitute when TE Connectivity parts are unavailable. This connector maintains all critical mechanical and electrical parameters including 40-position configuration, 0.100" pitch, dual-row arrangement, and card thickness accommodation. The Mercury part offers an extended operating temperature range of -40°C to 105°C and achieves ROHS3 Compliance with REACH Unaffected status. The contact finish thickness is reduced to 10.0µin (0.25µm), and the contact material is specified as Copper Alloy rather than Phosphor Bronze. These material differences do not preclude substitution for applications operating within the specified temperature envelope.

Selection between substitute parts should be based on compliance requirements, operating temperature specifications, and material composition compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-5530843-4 be used as a direct replacement for the 5-530843-4?

A: Yes. Both connectors share identical position count (40), pitch (0.100"), row configuration (2), gender (Female), card thickness accommodation (0.054" to 0.070"), mounting type (Through Hole), termination method (Solder), contact finish (Gold), and operating temperature range (-55°C to 85°C). The primary difference is RoHS compliance status, with the 5-5530843-4 being RoHS Compliant.

Q: What are the key differences between the TE Connectivity 5-530843-4 and the Mercury 395-040-520-201?

A: Both connectors maintain identical position count, pitch, row configuration, gender, card thickness range, mounting type, termination method, and contact finish material (Gold). The Mercury part features an extended operating temperature range (-40°C to 105°C versus -55°C to 85°C), uses Copper Alloy contacts instead of Phosphor Bronze, specifies Polyester Thermoplastic insulation instead of Glass-Filled Polyester, and has reduced contact finish thickness (10.0µin versus 30.0µin). The Mercury part achieves ROHS3 Compliance and REACH Unaffected status.

Q: Is the reduced contact finish thickness of the Mercury 395-040-520-201 a concern for substitution?

A: Contact finish thickness variation does not preclude substitution when the application requirements fall within the Mercury part's specified operating envelope. The 10.0µin (0.25µm) gold finish on the Mercury connector provides adequate contact protection for standard card edge connector applications. Selection should be based on specific application requirements and environmental conditions.

Q: What is the significance of the card thickness range specification?

A: The card thickness range of 0.054" to 0.070" (1.37mm to 1.78mm) defines the physical accommodation of the printed circuit board edge that inserts into the connector. All three parts maintain identical card thickness specifications, ensuring mechanical compatibility with the same PCB designs.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the application requirements fall within the operating specifications of the selected substitute part. The 5-5530843-4 is fully interchangeable with the 5-530843-4. The Mercury 395-040-520-201 is interchangeable when the application operates within its -40°C to 105°C temperature range and material composition compatibility is confirmed.

Q: What packaging options are available for these parts?

A: The TE Connectivity 5-530843-4 is available in standard packaging. The TE Connectivity 5-5530843-4 and Mercury 395-040-520-201 are both available in Bulk packaging.
