Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800805 is determined by strict alignment of the following critical parameters:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Number of positions: 34
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Contact shape: Square
• Contact finish - mating: Gold
• Contact finish - post: Tin
• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The TE Connectivity AMP Connectors part 6-146253-7 meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0702800805 and TE Connectivity 6-146253-7 are active products with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• PCB layout constraints related to contact post length differences (Molex: 0.185", TE: 0.125")
• Mechanical clearance requirements for overall contact length (Molex: 0.595", TE: 0.533")
• Application-specific operating temperature range (TE part specifies -65°C ~ 105°C)
• Current handling capacity (TE part specifies 3A rating)

Both connectors are suitable for automotive, medical, telecommunications, and general-purpose applications where UL94 V-0 rated insulation is required.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-146253-7 be used as a direct replacement for the Molex 0702800805?

A: Yes, the TE Connectivity part meets all critical substitution parameters including connector type, contact configuration, pitch, mounting method, and compliance certifications. Physical differences in contact post length and overall contact length must be evaluated against specific PCB design requirements.

Q: What are the key differences between these two connectors?

A: The primary differences are contact post length (Molex 0.185" vs. TE 0.125"), overall contact length (Molex 0.595" vs. TE 0.533"), and contact finish thickness on the post (Molex 74.8µin vs. TE 100.0µin). The TE part provides specified operating temperature range and current rating, while the Molex part does not include these specifications.

Q: Are both connectors RoHS compliant?

A: Yes, both the Molex 0702800805 and TE Connectivity 6-146253-7 are ROHS3 compliant.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special storage requirements.

Q: Do these connectors require special handling or storage?

A: With MSL 1 rating, both connectors do not require moisture-controlled storage or special handling procedures.

Q: Can these connectors be used in automotive applications?

A: Yes, both connectors are suitable for automotive applications and meet the required UL94 V-0 flammability rating for such use.
