Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-119254-9 is determined by strict alignment of the following critical parameters:

Position and Pitch Compatibility: The substitute connector must maintain 86 positions with 0.156" (3.96mm) pitch spacing to ensure mechanical and electrical compatibility with existing card edge designs.

Dual-Edge Configuration: The connector must support dual-edge card insertion with 2 rows of contacts to match the original contact arrangement.

Card Thickness Tolerance: The substitute must accommodate card thickness within the range of 0.054" to 0.071" (1.37mm to 1.80mm) to ensure proper contact engagement.

Contact Specifications: Gold plating at 30.0µin (0.76µm) thickness and female gender are required for direct interface compatibility.

Termination Method: Press-fit termination is the primary requirement for through-hole mounting applications.

Electrical and Mechanical Interface: The connector must function as a female card edge receiver with identical positional and dimensional characteristics.

The Mercury United Electronics 737-086-540-206 meets all critical substitution criteria while offering enhanced product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TE Connectivity 2-119254-9 is classified as obsolete, limiting long-term procurement viability. The Mercury 737-086-540-206 maintains active product status, ensuring continued availability and manufacturer support.

Compliance and Certification: The Mercury substitute achieves ROHS3 compliance and REACH unaffected status, addressing regulatory requirements that the original part does not satisfy. Both connectors share identical ECCN and HTSUS classifications.

Mechanical and Electrical Equivalence: The Mercury 737-086-540-206 maintains full compatibility across all critical parameters including position count, pitch spacing, card thickness tolerance, contact finish specifications, and mounting configuration. The card thickness tolerance of the substitute (0.054" ~ 0.070") encompasses the functional range of the original part.

Termination Flexibility: The Mercury substitute offers both press-fit and wire wrap termination options, providing additional application flexibility while maintaining press-fit compatibility with existing designs.

Contact Material Difference: The Mercury connector uses copper alloy contacts with cantilever design, compared to the phosphor bronze contacts in the original part. Both materials with identical gold plating thickness (30.0µin) provide equivalent electrical performance for card edge applications.

Frequently Asked Questions (FAQ)

Q: Can the Mercury 737-086-540-206 directly replace the TE Connectivity 2-119254-9 in existing applications?

A: Yes. Both connectors maintain identical position count (86), pitch spacing (0.156"), dual-edge configuration, and gold contact finish thickness. The card thickness tolerance of the Mercury connector (0.054" ~ 0.070") is compatible with the original specification range.

Q: What is the significance of the card thickness tolerance difference?

A: The Mercury substitute specifies 0.054" ~ 0.070" (1.37mm ~ 1.78mm) compared to the original 0.054" ~ 0.071" (1.37mm ~ 1.80mm). This represents a 0.001" (0.02mm) reduction at the upper limit. This difference is negligible for standard card edge applications and does not affect functional compatibility.

Q: Does the copper alloy contact material in the Mercury connector affect performance?

A: No. Both phosphor bronze and copper alloy contacts with identical gold plating thickness (30.0µin) provide equivalent electrical conductivity and contact resistance characteristics for card edge connector applications.

Q: What are the advantages of the Mercury substitute's dual termination capability?

A: The Mercury 737-086-540-206 supports both press-fit and wire wrap termination methods. This provides design flexibility for applications requiring wire wrap connections while maintaining full press-fit compatibility with existing through-hole designs.

Q: How does the RoHS3 compliance of the Mercury connector affect system integration?

A: ROHS3 compliance ensures the Mercury connector meets current environmental and regulatory standards for electronic component manufacturing. This is particularly important for new designs and systems requiring compliance documentation.

Q: Are there any packaging differences between the two connectors?

A: The Mercury 737-086-540-206 is supplied in box packaging. Packaging format does not affect connector functionality or compatibility.

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

A: The Mercury 737-086-540-206 maintains 1012 pieces in active stock as a new original component, ensuring reliable procurement availability.
