Molex 0702800643 Equivalent & Substitute Parts

Part Overview

The Molex 0702800643 is a vertical rectangular connector header with 30 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This connector is part of the C-Grid 70280 series and is actively manufactured. Substitute parts are necessary when the primary part is unavailable, when design requirements demand alternative material specifications, or when compliance certifications differ from project requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800643 is determined by strict alignment of the following critical parameters:

Core Electrical & Mechanical Compatibility:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 30
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header, Breakaway
Contact Type: Male Pin

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The TE Connectivity 6-146257-5, Amphenol ICC 77313-801-30LF, and Sullins PBC15DAAN are the preferred substitutes. All three are actively manufactured, RoHS3 compliant, and maintain the core 30-position, 2.54mm pitch configuration. The 6-146257-5 offers the closest material alignment with LCP insulation. The 77313-801-30LF and PBC15DAAN provide extended operating temperature ranges (-65°C to 130°C and -65°C to 125°C respectively) compared to the primary part.

Secondary Substitutes (Active Status, Compliance Variations):

The Amphenol ICC 77313-118-30LF and Sullins PEC15DAAN are active alternatives with RoHS compliance. The 77313-118-30LF features extended post length (0.120") and higher insulation height (0.100"). The PEC15DAAN uses tin mating finish instead of gold, which affects contact durability characteristics.

Obsolete Alternative (Not Recommended for New Designs):

The TE Connectivity 4-103186-0-15 is obsolete and RoHS non-compliant. This part is listed for reference only in legacy system support scenarios.

Extended Post Length Variant:

The Sullins PBC15DADN features significantly longer post length (0.420") and overall contact length (0.750"), suitable only for applications requiring deeper PCB penetration or specific mechanical clearance requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0702800643 with any of these parts directly?

A: Yes, all listed parts maintain the core 30-position, 2.54mm pitch header configuration with identical connector type, contact type, and mounting specifications. Mechanical and electrical interfaces are compatible. Physical dimensions vary slightly due to contact length and insulation height differences, which may affect PCB layout spacing.

Q: What is the difference between the Amphenol ICC BERGSTIK® parts (77313-101-30LF, 77313-118-30LF, 77313-801-30LF)?

A: The primary differences are post length and contact finish thickness. The 77313-101-30LF and 77313-801-30LF have shorter posts (0.095"), while the 77313-118-30LF has longer posts (0.120"). The 77313-801-30LF has thinner mating finish (15.0µin) compared to the others (30.0µin). All three are RoHS compliant and actively manufactured.

Q: Why is the TE Connectivity 4-103186-0-15 listed if it is obsolete?

A: This part is included for reference in applications where legacy system compatibility or existing inventory must be maintained. It is not recommended for new designs due to obsolete status and RoHS non-compliance.

Q: What is the significance of the Sullins PBC15DADN having a much longer post length?

A: The PBC15DADN post length of 0.420" (versus 0.120" in standard variants) is designed for applications requiring deeper PCB penetration or specific mechanical clearance. This variant is suitable only for designs with compatible PCB thickness and mounting requirements.

Q: Are there compliance differences I should consider?

A: Yes. The Molex 0702800643 and most substitutes are ROHS3 compliant. The TE Connectivity 4-103186-0-15 is RoHS non-compliant and should not be used in applications requiring RoHS certification. The Amphenol ICC 77313-801-30LF and Sullins parts (PBC15DAAN, PBC15DADN, PEC15DAAN) are all ROHS3 compliant.

Q: What is the difference between gold and tin mating finishes?

A: Gold finish (used on most substitutes) provides superior corrosion resistance and contact durability. Tin finish (used on the Sullins PEC15DAAN) offers lower cost but reduced contact longevity in high-cycle mating applications. Both finishes are electrically functional.

Q: Can I use the PEC15DAAN if my application requires gold plating?

A: No. The PEC15DAAN uses tin mating finish exclusively. If gold mating finish is a design requirement, select from PBC15DAAN, PBC15DADN, or the Amphenol ICC or TE Connectivity alternatives.

Q: What operating temperature range should I specify?

A: The Molex 0702800643 does not specify an operating temperature range. Substitutes range from -65°C to 105°C (TE Connectivity 6-146257-5) to -65°C to 130°C (Amphenol ICC BERGSTIK® series). Select based on your application requirements.
