Molex 0702800801 Equivalent & Substitute Parts

Part Overview

The Molex 0702800801 is a rectangular connector header designed for through-hole mounting applications. This vertical 26-position connector operates at 0.100" (2.54mm) pitch and features a 2-row configuration with unshrouded, breakaway design. The part is currently active in production with 627 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers offer improved lead times, or when design requirements allow for functionally equivalent alternatives that meet the same electrical and mechanical specifications.

Engineering Selection Recommendations

Active Status Parts (Recommended for New Designs):

TE Connectivity 6-146252-3 and 6-146253-3 are both active production parts with substantial inventory availability (64,520 and 5,523 units respectively). Both meet ROHS3 compliance and maintain the same core electrical and mechanical specifications as the Molex 0702800801. The primary difference between these two TE parts is contact finish thickness on the mating surface (15.0µin versus 30.0µin), with 6-146253-3 offering thicker gold plating. Both operate across -65°C to 105°C with 3A current rating per contact.

Amphenol ICC BERGSTIK® series parts 77313-127-26LF and 77313-824-26LF are active production alternatives with extended operating temperature range (-65°C to 130°C). These parts feature phosphor bronze contact material and thermoplastic insulation, with 1,143 and 893 units in stock respectively. The BERGSTIK® series offers higher temperature capability and maintains RoHS compliance with REACH Affected status for 77313-127-26LF and REACH Unaffected status for 77313-824-26LF.

3M 929665-01-13-I is an active production part with 7,386 units in stock. This part operates at -40°C to 105°C with 2.5A current rating and features copper alloy contacts with gold finish. It maintains RoHS compliance and REACH Unaffected status.

Obsolete Status Parts (Not Recommended for New Designs):

TE Connectivity 6-146264-3 is marked as obsolete and should not be selected for new designs despite meeting core substitution criteria. This part features kinked pin termination in addition to solder termination, distinguishing it from other alternatives.

Compliance Considerations:

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level, matching the original Molex specification. RoHS compliance is confirmed across all active parts. REACH status varies: 6-146252-3 shows Vendor Undefined, 6-146253-3 is REACH Unaffected, 77313-127-26LF is REACH Affected, 77313-824-26LF is REACH Unaffected, and 929665-01-13-I is REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the Molex 0702800801?

A: The connector must maintain 26 positions in a 2-row configuration at 0.100" (2.54mm) pitch with 0.100" row spacing. It must be a through-hole mounted header with male pins, square contact shape, gold mating finish, push-pull fastening, solder termination, and UL94 V-0 flammability rating. Contact material must be copper alloy or phosphor bronze. Insulation must be black with MSL 1 rating. RoHS compliance is required.

Q: Can I use parts with different contact lengths?

A: Contact length variations exist among the substitute parts listed. The Molex 0702800801 has a mating contact length of 0.320" (8.13mm), while substitutes range from 0.235" to 0.318". These differences do not disqualify substitution when all other core parameters match, but board layout and mating connector depth must be verified for mechanical compatibility.

Q: What is the difference between the TE 6-146252-3 and 6-146253-3?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is contact finish thickness on the mating surface: 6-146252-3 has 15.0µin (0.38µm) gold plating, while 6-146253-3 has 30.0µin (0.76µm) gold plating. The thicker plating on 6-146253-3 may provide enhanced durability in high-cycle mating applications.

Q: Why do the Amphenol BERGSTIK® parts have different operating temperature ranges?

A: Both Amphenol parts (77313-127-26LF and 77313-824-26LF) operate across -65°C to 130°C, providing extended temperature capability compared to the TE and 3M alternatives. This extended range does not affect substitution eligibility when the application does not require temperatures below -40°C or above 105°C.

Q: Should I avoid the TE 6-146264-3 part?

A: Yes. The TE 6-146264-3 is marked as obsolete and should not be selected for new designs. While it meets core substitution criteria, its obsolete status indicates discontinued production and potential future unavailability.

Q: What is the difference in current rating between the 3M 929665-01-13-I and other substitutes?

A: The 3M part is rated for 2.5A per contact, while TE and Amphenol alternatives are rated for 3A per contact. This lower current rating must be considered if the application requires the full 3A capability per contact.

Q: Are all these parts RoHS compliant?

A: Yes. All active production substitute parts listed are RoHS compliant. The Molex 0702800801 is ROHS3 compliant, while substitute parts are either ROHS3 compliant (TE parts) or RoHS compliant (Amphenol and 3M parts). This difference does not affect substitution eligibility.

Q: What packaging options are available?

A: All substitute parts are supplied in bulk packaging, matching the Molex 0702800801 packaging specification.
