Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0702800828 is determined by strict adherence to the following critical parameters:

Primary Substitution Criteria:

Number of Positions: 80
Number of Rows: 2
Pitch - Mating: 0.100" (2.54mm)
Row Spacing - Mating: 0.100" (2.54mm)
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Style: Board to Board or Cable
Shrouding: Unshrouded
Contact Shape: Square

All identified substitute parts meet these core electrical and mechanical parameters. Variations in contact length, contact finish materials, insulation materials, and contact finish thickness do not preclude substitution when the primary criteria are satisfied. Differences in operating temperature ranges, RoHS compliance status, and contact material composition are secondary considerations that may apply to specific application requirements but do not eliminate functional equivalence for standard board-to-board header applications.

Engineering Selection Recommendations

Primary Selection - Molex 0702800828: The original Molex 0702800828 is ROHS3 compliant and maintains active production status. This part is suitable for applications requiring full RoHS3 compliance and is the preferred choice when supply is available.

Recommended Substitutes - Sullins Connector Solutions (PREC040DFAN-RC, PRPC040DFAN-RC, PRPC040DFBN-RC): All three Sullins alternatives are ROHS3 compliant and maintain active production status. These parts provide direct functional equivalence with the Molex 0702800828 across all critical electrical and mechanical parameters. The Sullins parts offer higher inventory availability (2254 to 8014 units in stock) compared to the original part. Selection among the three Sullins variants depends on specific contact post length and finish requirements:

PREC040DFAN-RC: Tin mating finish, tin post finish
PRPC040DFAN-RC: Gold mating finish, gold post finish, standard post length
PRPC040DFBN-RC: Gold mating finish, gold post finish, extended post length

Alternative Substitute - TE Connectivity 4-87227-0: The TE Connectivity AMPMODU Mod II 4-87227-0 meets all primary substitution criteria with active production status. RoHS status is listed as not applicable. This part features phosphor bronze contact material and gold plating on both mating and post surfaces. Operating temperature range extends to -65°C, providing broader thermal performance than the original part.

Non-Recommended Substitute - 3M 2380-6221-TG: The 3M 2380-6221-TG is not RoHS compliant and does not meet current regulatory requirements for new designs. This part is listed for reference only and is not recommended for new applications.

Frequently Asked Questions (FAQ)

Q: Can the Sullins PRPC040DFBN-RC be used as a direct replacement for the Molex 0702800828? A: Yes. The Sullins PRPC040DFBN-RC meets all critical substitution parameters: 80 positions, 2 rows, 0.100" pitch, male pin contacts, through-hole mounting, solder termination, and push-pull fastening. The extended post length (0.220" vs. 0.185") does not affect functional compatibility in standard board-to-board applications. Both parts are ROHS3 compliant and carry MSL 1 rating.

Q: What is the difference between PRPC040DFAN-RC and PRPC040DFBN-RC? A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is contact post length: PRPC040DFAN-RC has 0.120" post length, while PRPC040DFBN-RC has 0.220" post length. Selection depends on PCB thickness and solder joint requirements. Both feature gold plating on mating and post surfaces.

Q: Is the TE Connectivity 4-87227-0 suitable for automotive applications? A: The TE Connectivity 4-87227-0 meets the core mechanical and electrical requirements for automotive connector applications. However, RoHS compliance status is listed as not applicable. Verify compliance with specific automotive standards and RoHS requirements for your application before selection.

Q: Why does the 3M 2380-6221-TG appear in the substitute list if it is not RoHS compliant? A: The 3M 2380-6221-TG is included for reference and historical compatibility purposes. It meets all primary electrical and mechanical substitution criteria but does not meet current regulatory compliance requirements. This part is not recommended for new designs or applications requiring RoHS3 compliance.

Q: Are all substitute parts available in the same packaging format? A: Yes. All listed substitute parts are supplied in bulk packaging, matching the original Molex 0702800828 packaging format. Inventory availability varies by manufacturer and part number, with Sullins parts offering the highest stock levels (2254 to 8014 units).

Q: What is the impact of different contact materials on connector performance? A: The Molex 0702800828 uses copper alloy contacts, while substitute parts use copper alloy, phosphor bronze, or brass. All materials are suitable for standard signal and power applications at the specified current ratings. Contact material selection does not affect functional compatibility for board-to-board header applications operating within the specified electrical parameters.
