Key Parameters

Substitute Part Grouping Explanation

Substitution of the 50865-3 terminal connector is determined by strict equivalence across the following critical parameters:

Pin Acceptance Compatibility: The substitute part must accept the identical pin diameter range of 0.034" to 0.041" (0.86mm to 1.04mm) to ensure mechanical fit and electrical contact integrity.

Mechanical Configuration: The substitute must maintain identical tail type (no tail), overall length (0.260" / 6.60mm), socket depth (0.247" / 6.27mm), mounting hole diameter (0.072" / 1.83mm), and flange diameter (0.089" / 2.26mm) to ensure compatibility with existing PCB layouts and connector housings.

Electrical and Material Properties: The substitute must feature beryllium copper contacts with gold plating at 30.0µin (0.76µm) thickness and solder termination to maintain electrical performance and reliability characteristics.

Environmental Performance: The substitute must support the operating temperature range of -65°C to 125°C and maintain MSL 1 (Unlimited) moisture sensitivity classification.

Series Classification: The substitute must belong to Series 4 to ensure compatibility with associated connector components and assemblies.

Parameter Comparison

Engineering Selection Recommendations

The 5050865-3 serves as a direct functional substitute for the obsolete 50865-3 terminal connector. Both components share identical mechanical dimensions, electrical specifications, and material compositions across all critical parameters.

Product Status Consideration: The 50865-3 is classified as obsolete, while the 5050865-3 maintains active product status with significantly higher inventory availability (42,616 pieces versus 1,090 pieces). Selection of the active substitute ensures long-term supply chain continuity and supports ongoing production schedules.

Compliance Advantage: The 5050865-3 achieves ROHS3 compliance, whereas the 50865-3 is RoHS non-compliant. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, the 5050865-3 provides the necessary certification alignment.

Operating Temperature Range: The 5050865-3 extends the upper operating temperature limit to 126°C compared to the 50865-3 specification of 125°C. This marginal extension does not restrict substitution and provides additional thermal margin for demanding applications.

Mechanical and Electrical Equivalence: All mechanical dimensions, pin acceptance specifications, contact materials, and electrical properties remain identical between the two components, ensuring direct interchangeability within existing designs and assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 5050865-3 be used as a direct replacement for the 50865-3 in existing designs?

A: Yes. The 5050865-3 is mechanically and electrically equivalent to the 50865-3 across all critical parameters including pin diameter acceptance (0.034" ~ 0.041"), overall length (0.260"), socket depth (0.247"), mounting hole diameter (0.072"), flange diameter (0.089"), contact material (beryllium copper), contact finish (gold at 30.0µin), and operating temperature range (-65°C to 125°C minimum). Direct substitution is supported without design modification.

Q: What is the difference in packaging between the 50865-3 and 5050865-3?

A: The 50865-3 is supplied in unspecified packaging, while the 5050865-3 is supplied in bulk packaging. Both components are identical in form, fit, and function. Packaging differences do not affect component performance or compatibility.

Q: Why is the 50865-3 classified as obsolete?

A: The 50865-3 has been superseded by the 5050865-3, which maintains active product status. The 5050865-3 provides identical functionality with improved compliance certifications and superior supply availability.

Q: Does the RoHS3 compliance of the 5050865-3 affect compatibility with designs originally specified for the non-compliant 50865-3?

A: No. RoHS3 compliance of the 5050865-3 represents an improvement in environmental and regulatory alignment. The component remains mechanically and electrically equivalent, and RoHS compliance does not introduce incompatibility with existing designs or assemblies.

Q: Are there any electrical performance differences between the 50865-3 and 5050865-3?

A: No. Both components feature identical contact material (beryllium copper), contact finish (gold), contact finish thickness (30.0µin / 0.76µm), and solder termination. Electrical performance characteristics are equivalent.

Q: What is the significance of the Series 4 classification?

A: Series 4 is the connector series designation for both the 50865-3 and 5050865-3. This classification ensures compatibility with other Series 4 connector components and assemblies. Substitution between parts of the same series maintains system-level compatibility.

Q: Can the 5050865-3 accommodate the same pin diameter range as the 50865-3?

A: Yes. Both components accept pin diameters of 0.034" to 0.041" (0.86mm to 1.04mm). Pin acceptance specifications are identical, ensuring mechanical fit and electrical contact with existing pin components.

Q: Is the extended operating temperature range of the 5050865-3 (-65°C to 126°C versus -65°C to 125°C) a limiting factor for substitution?

A: No. The extended upper temperature limit of the 5050865-3 provides additional thermal margin and does not restrict substitution. Applications designed for the 50865-3 operating range are fully supported by the 5050865-3 specification.
