Molex 0702800833 Equivalent & Substitute Parts
Part Overview
The Molex 0702800833 is a vertical rectangular connector header with 10 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This through-hole component features male pins with solder termination and is designed for board-to-board or cable applications. The connector is manufactured from copper alloy contacts with liquid crystal polymer insulation and tin contact finish. With 706 units in current stock and active product status, this component serves general purpose, automotive, lighting, medical, and telecommunications applications.
Substitute parts are necessary when the original part becomes unavailable, when alternative compliance requirements must be met (such as RoHS3 compliance versus non-compliant alternatives), or when specific contact finish or insulation material specifications are required for particular application environments.

Engineering Selection Recommendations
For RoHS3 Compliant Applications:
TE Connectivity 5-146257-5 is the primary recommendation for new designs requiring RoHS3 compliance. This part maintains active product status with the highest inventory availability (210,258 units), ensuring long-term supply continuity. It features gold-plated mating contacts (30.0µin thickness) with tin-plated posts, LCP insulation, and operates across -65°C to 105°C. The shorter post length (0.120") and reduced overall contact length (0.440") compared to the Molex 0702800833 require PCB layout verification.
TE Connectivity 5-146258-5 and 5-146261-5 provide alternative RoHS3-compliant options with identical electrical specifications but shorter post lengths (0.090"), resulting in overall contact lengths of 0.410". These variants are suitable for applications with space constraints or specific PCB thickness requirements.
TE Connectivity 5-146254-5 offers RoHS3 compliance with tin-plated mating contacts and LCP insulation, providing cost optimization for applications where gold plating is not required. Inventory availability is substantial at 6,313 units.
For Legacy or Non-Compliant Applications:
TE Connectivity 4-103186-0-05, 4-103328-0-05, and 4-103783-0-05 are obsolete parts suitable only for legacy design maintenance or repair. These parts feature thermoplastic insulation and various contact finishes (gold, tin-lead, or tin-lead combinations). Inventory is limited (664 to 1,885 units), and product status is obsolete, making them unsuitable for new production designs.
3M 2310-6121-TG is RoHS non-compliant and features gold-plated mating contacts with tin-lead posts and thermoplastic glass-filled insulation. Operating temperature range extends to 105°C. This part is suitable only for applications where RoHS compliance is not mandated.
For Extended Temperature Range Applications:
Amphenol ICC (FCI) 67996-110HLF and 67996-210HLF provide extended operating temperature range (-65°C to 125°C) with RoHS compliance. These parts feature phosphor bronze contacts with gold or gold GXT™ plating and are available in bag packaging. The 67996-110HLF offers 30.0µin gold plating thickness, while 67996-210HLF provides 15.0µin thickness. Inventory levels are adequate (2,471 to 5,680 units), and both maintain active product status.
Frequently Asked Questions (FAQ)
Q: Can I use TE 5-146254-5 as a direct replacement for Molex 0702800833?
A: Yes, TE 5-146254-5 is electrically and mechanically compatible. Both connectors maintain 10 positions in 2 rows at 0.100" pitch with male pins, through-hole solder termination, and UL94 V-0 flammability rating. The primary difference is the contact post length: TE 5-146254-5 has 0.120" posts versus Molex's 0.200" posts. This requires verification that your PCB thickness and component layout accommodate the shorter post length. Both parts are RoHS3 compliant.
Q: What is the difference between TE 5-146257-5, 5-146258-5, and 5-146261-5?
A: All three are RoHS3-compliant AMPMODU Mod II headers with identical electrical specifications and operating temperature ranges (-65°C to 105°C). The differences are:
- 5-146257-5: Gold-plated mating contacts (30.0µin), tin-plated posts, 0.120" post length
- 5-146258-5: Tin-plated mating contacts, tin-plated posts, 0.090" post length
- 5-146261-5: Gold-plated mating contacts (30.0µin), tin-plated posts, 0.090" post length
Selection depends on contact finish requirements and available PCB thickness. The 0.090" post length variants are suitable for thinner PCBs or space-constrained designs.
Q: Are the obsolete TE parts (4-103186-0-05, 4-103328-0-05, 4-103783-0-05) suitable for new production?
A: No. These parts carry obsolete product status and limited inventory (664 to 1,885 units). They are suitable only for legacy design maintenance, repair, or replacement of existing assemblies. For new production designs, select from active parts: TE 5-146254-5, 5-146257-5, 5-146258-5, 5-146261-5, or Amphenol 67996-110HLF/67996-210HLF.
Q: What is the difference between RoHS3 Compliant and RoHS non-compliant parts?
A: RoHS3-compliant parts (TE 5-146254-5, 5-146257-5, 5-146258-5, 5-146261-5, and Amphenol 67996-110HLF/67996-210HLF) meet the Restriction of Hazardous Substances Directive and contain no lead, mercury, cadmium, or other restricted substances. RoHS non-compliant parts (3M 2310-6121-TG and obsolete TE parts) may contain lead or other restricted materials. Use RoHS3-compliant parts for all new designs unless application-specific requirements mandate otherwise.
Q: Why does Molex 0702800833 have a longer post length (0.200") than most substitutes?
A: The longer post length accommodates thicker PCBs or applications requiring deeper solder penetration. Most substitute parts use 0.090" to 0.120" post lengths, which are standard for typical PCB thicknesses (0.062" to 0.093"). If your design requires the longer post length, verify that substitute parts with shorter posts are compatible with your PCB thickness before selection.
Q: Can I use Amphenol 67996-110HLF or 67996-210HLF in place of Molex 0702800833?
A: Yes, both Amphenol parts are mechanically and electrically compatible. Key advantages include extended operating temperature range (-65°C to 125°C versus unspecified for Molex), RoHS compliance, and phosphor bronze contacts with gold plating. The primary consideration is post length: Amphenol parts have 0.095" posts, requiring PCB layout verification. Both parts are available in bag packaging rather than bulk.
Q: What is the significance of contact finish thickness (µin)?
A: Contact finish thickness affects durability and wear resistance. Molex 0702800833 specifies 150.0µin (3.81µm) tin plating on mating contacts, providing robust protection. Substitute parts range from 10.0µin (3M 2310-6121-TG) to 100.0µin (TE 5-146254-5, 5-146258-5). Thicker finishes provide longer service life in high-cycle mating applications. For standard applications, 30.0µin to 100.0µin is adequate.
Q: Are there packaging differences between substitute parts?
A: Yes. Molex 0702800833 and most TE parts are supplied in bulk packaging. Amphenol 67996-110HLF and 67996-210HLF are supplied in bag packaging. Bulk packaging is standard for high-volume production; bag packaging is typical for lower-volume or kit applications. Verify packaging requirements with your procurement process.
