Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0719730313 is determined by strict alignment of the following core parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 26 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Fastening Mechanism: Push-pull fastening type
• Mating Contact Finish: Gold plating on mating surfaces
• Flammability Compliance: UL94 V-0 rating

The TE Connectivity AMP Connectors part number 2-535512-0 meets all core substitution criteria. Variations in insulation height, post contact length, and post finish material do not preclude substitution when the mating interface and mechanical mounting remain functionally equivalent.

Parameter Comparison

Engineering Selection Recommendations

Molex 0719730313 is the primary specification when RoHS3 compliance is required. This part carries full RoHS3 certification and is REACH unaffected, making it suitable for applications with strict environmental compliance mandates. Current inventory of 1058 units supports immediate procurement.

TE Connectivity 2-535512-0 serves as a functional substitute when extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 105°C) is required. This part is suitable for applications operating in extreme thermal environments. However, this substitute is RoHS non-compliant and REACH affected, restricting its use to applications where environmental regulations do not apply. The TE part is available in tube packaging with 1167 units in stock.

Both parts share identical mating pitch, position count, row configuration, fastening mechanism, and gold contact finish. Mechanical variations in insulation height and post contact length are within acceptable tolerances for standard PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-535512-0 directly replace the Molex 0719730313 in all applications?

A: Direct replacement is possible from a mechanical and electrical mating perspective due to identical pitch, position count, row spacing, and contact finish. However, regulatory compliance differs. The Molex part is RoHS3 compliant; the TE part is not. Application requirements determine suitability.

Q: What is the significance of the 0.014" (0.36mm) difference in insulation height?

A: The TE Connectivity part has a 0.238" (6.05mm) insulation height compared to the Molex 0.224" (5.69mm). This minor dimensional variation does not affect mating compatibility or standard PCB mounting when clearance is adequate. Verify PCB layout constraints in space-restricted designs.

Q: Why does the TE part have a lower post contact length (0.115" versus 0.120")?

A: The 0.005" (0.127mm) difference in post contact length reflects design variations between manufacturers. Both lengths are within acceptable solder joint formation parameters for standard through-hole PCB assembly processes.

Q: What does RoHS3 compliance mean for the Molex part?

A: RoHS3 compliance indicates the Molex 0719730313 meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. This certification is mandatory for applications in regulated markets including automotive and medical devices.

Q: Is the TE Connectivity part suitable for automotive applications?

A: The TE part meets UL94 V-0 flammability requirements and operates across -55°C ~ 125°C. However, RoHS non-compliance and REACH-affected status may disqualify it from automotive applications subject to environmental regulations. Verify application-specific compliance requirements.

Q: What is the difference between tin and tin-lead post finishes?

A: The Molex part uses tin post finish; the TE part uses tin-lead. Tin-lead finishes are restricted in RoHS-compliant applications. This difference reinforces the regulatory distinction between the two parts.

Q: Can both parts be used interchangeably in medical device applications?

A: Medical device applications typically require RoHS compliance and full regulatory traceability. The Molex 0719730313 is suitable; the TE Connectivity 2-535512-0 is not recommended due to RoHS non-compliance.
