Equivalent & Substitute Parts for 50-6SN-5 Card Edge Connector

Part Overview

The 50-6SN-5 is a 12-position female card edge connector manufactured by Cinch Connectivity Solutions. This connector features dual edge configuration with 0.156" (3.96mm) pitch spacing and gold-plated bifurcated semi-bellows contacts. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and procurement planning. Equivalent parts must maintain functional compatibility across critical electrical and mechanical parameters while accommodating modern supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 50-6SN-5 is determined by strict alignment with the following parameters:

• Connector Configuration: Dual edge, female gender, 12-position arrangement (6 positions per row)
• Pitch Specification: 0.156" (3.96mm) center-to-center spacing
• Card Thickness Compatibility: Acceptable range 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Contact Finish: Gold plating at 10.0µin (0.25µm) thickness
• Termination Method: Solder attachment to PCB
• Flange Geometry: Flush mount, top opening configuration with 0.128" (3.25mm) diameter unthreaded holes
• Mounting Style: Through hole PCB mounting

The substitute part 356-006-520-102 satisfies these core substitution criteria. Variations in contact type (cantilever vs. bifurcated semi-bellows), read-out configuration (dual vs. single), and operating temperature range do not preclude functional substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 356-006-520-102 from Mercury United Electronics, Inc. serves as a direct functional substitute for the obsolete 50-6SN-5. Selection of this substitute is supported by the following factors:

Compliance and Availability: The 356-006-520-102 maintains active product status with ROHS3 compliance and REACH unaffected designation, providing regulatory alignment for modern procurement requirements. The 50-6SN-5 is RoHS non-compliant and obsolete, creating supply chain risk.

Electrical and Mechanical Compatibility: Both connectors share identical pitch (0.156"), position count (12), gender (female), and flange geometry. Card thickness acceptance ranges are compatible within the 0.054" ~ 0.070" overlap window. Gold contact finish specifications match at 10.0µin (0.25µm).

Operating Conditions: The substitute part operates across -40°C ~ 105°C, which covers the upper temperature range of the original part. Applications requiring the full -65°C lower temperature limit of the 50-6SN-5 must evaluate the narrower operating range of the substitute.

Contact and Material Differences: The substitute employs cantilever contacts and copper alloy base material versus the original's bifurcated semi-bellows and brass construction. These differences do not prevent substitution when electrical performance requirements align with the substitute's specifications.

Frequently Asked Questions (FAQ)

Q: Can the 356-006-520-102 directly replace the 50-6SN-5 in existing PCB designs?

A: Yes, for applications within the -40°C ~ 105°C operating range. Both connectors share identical pitch (0.156"), position configuration (12-position dual), flange geometry, and solder termination. PCB footprints and mounting hole patterns are compatible. Applications requiring operation below -40°C must evaluate the substitute's performance specifications.

Q: What is the significance of the different contact types (bifurcated semi-bellows vs. cantilever)?

A: Contact type affects mechanical engagement and contact force characteristics. The bifurcated semi-bellows design of the original provides dual contact points per position, while the cantilever design of the substitute provides single contact engagement. Both designs are suitable for 0.156" pitch card edge applications when properly specified for the intended electrical load and insertion cycle requirements.

Q: Are there compatibility concerns with the different insulation materials?

A: The original uses polyester glass-filled insulation; the substitute uses polyester thermoplastic. Both materials are suitable for through-hole solder termination and the specified operating temperature range of the substitute (-40°C ~ 105°C). Material selection does not affect mechanical compatibility or electrical performance in standard card edge connector applications.

Q: Why is the card thickness range slightly different between the two parts?

A: The 50-6SN-5 accepts cards 0.054" ~ 0.071" thick, while the 356-006-520-102 accepts 0.054" ~ 0.070" thick cards. The overlap range (0.054" ~ 0.070") is compatible. Cards thicker than 0.070" are not suitable for the substitute. Verify your card thickness specification falls within the 0.054" ~ 0.070" window before substitution.

Q: What is the inventory status for the substitute part?

A: The 356-006-520-102 has 1,080 pieces in stock as new original inventory, providing immediate availability. The original 50-6SN-5 has 945 pieces available but is classified as obsolete with no future production planned.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The 356-006-520-102 is ROHS3 compliant and REACH unaffected. The original 50-6SN-5 is RoHS non-compliant. For applications subject to RoHS or REACH regulations, the substitute provides regulatory alignment.
