Molex 0702800765 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0702800765 is a vertical rectangular connector header designed for through-hole mounting applications. This 34-position, 2-row connector operates at 0.100" (2.54mm) pitch and features male pins with gold-plated mating contacts and tin-plated posts. The connector is classified as Active product status and is widely used in automotive, medical, telecommunications, and general-purpose applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800765 is determined by strict equivalence across the following critical parameters:

• 34-position connector with 2-row configuration
• 0.100" (2.54mm) mating pitch and row spacing
• Male pin contact type with through-hole solder termination
• Gold-plated mating contacts and tin-plated posts
• Unshrouded header design with breakaway capability
• Board-to-board or cable connection style
• Liquid Crystal Polymer insulation material
• UL94 V-0 flammability rating
• ROHS3 compliance and MSL 1 classification

The TE Connectivity AMP Connectors part 6-146253-7 meets all critical substitution criteria and is qualified as a direct equivalent for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0702800765 and TE Connectivity 6-146253-7 are Active product status components with full ROHS3 compliance and identical regulatory classifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Supplier qualification and procurement agreements
• Series-specific design documentation requirements for your application
• Contact geometry variations: The Molex part features contact lengths of 0.320" mating and 0.185" post, while the TE part specifies 0.318" mating and 0.125" post. These minor dimensional differences are within standard connector tolerance ranges for 2.54mm pitch headers.
• Operating temperature specification: The TE part provides explicit operating temperature range of -65°C to 105°C; the Molex part does not specify this parameter in the provided data.
• Current rating: The TE part specifies 3A current rating; the Molex part does not provide this specification in the available data.

Both parts are suitable for automotive, medical, telecommunications, and general-purpose applications where UL94 V-0 flammability compliance is required.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-146253-7 be used as a direct replacement for the Molex 0702800765?

A: Yes. Both connectors share identical critical specifications: 34-position, 2-row configuration at 0.100" (2.54mm) pitch, male pin headers with through-hole solder termination, gold-plated mating contacts, and UL94 V-0 compliance. The connectors are mechanically and electrically compatible for standard board-to-board applications.

Q: What are the key differences between these two connector models?

A: The primary differences are manufacturer series designation (C-Grid 70280 versus AMPMODU Mod II) and minor contact geometry variations. The TE part provides explicit operating temperature (-65°C to 105°C) and current rating (3A) specifications, while the Molex part does not include these parameters in the available technical data. Contact post lengths differ slightly: 0.185" for Molex versus 0.125" for TE Connectivity.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0702800765 and TE Connectivity 6-146253-7 are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) classification.

Q: What applications are these connectors suitable for?

A: The Molex 0702800765 is specified for automotive, general purpose, lighting, medical, and telecommunications applications. Both connectors meet UL94 V-0 flammability requirements suitable for these industrial and commercial sectors.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. Current inventory levels differ: Molex 0702800765 has 957 pieces in stock, while TE Connectivity 6-146253-7 has 2647 pieces available. Inventory status should be verified at time of procurement.
