Substitute Part Grouping Explanation

Substitution for the Molex 0015876043 is determined by the following critical parameters: 50 position count, 2-row configuration, receptacle connector type, through-hole right-angle mounting, solder termination, outer shroud contact style, board lock and shielding features, and gold contact finish. Substitute parts must maintain these core electrical and mechanical characteristics to ensure functional compatibility.

The substitute parts are grouped into two categories based on connector style and mounting approach:

Category 1: 3M Mini D Ribbon (MDR) Series — Parts 10250-55F3PC, 10250-55G3PC, 10250-55H3PC, N10250-5242PC, N10250-52B2PC, and N10250-52E2PC maintain the 50-position receptacle configuration with panel mount and through-hole right-angle solder termination. These parts differ in flange feature specifications (M2.6 or 4-40 screw sizes) and packaging formats.

Category 2: TE Connectivity AMPLIMITE .050 III Series — Parts 5787082-5, 5787170-5, and 787082-5 provide D-type receptacle configurations with 50 positions, board edge and through-hole right-angle mounting, and solder termination. These parts feature D-type connector styling with female sockets and differ in flange specifications (2-56 or 4-40).

Category 3: TE Connectivity CHAMP .050 II Series — Part 5178238-7 offers a 50-position receptacle with panel mount and through-hole right-angle solder termination, featuring board-side flange mounting with M2.6 specification.

Engineering Selection Recommendations

For applications requiring direct functional replacement of the obsolete Molex 0015876043, the 3M 10250 series (10250-55F3PC, 10250-55G3PC, 10250-55H3PC) and 3M N10250 series (N10250-5242PC, N10250-52B2PC, N10250-52E2PC) provide the closest electrical and mechanical compatibility. These parts maintain outer shroud contact styling, 50-position configuration, board lock and shielding features, and gold contact finish specifications. All 3M alternatives are active products with RoHS compliance, ensuring long-term availability and regulatory alignment.

The TE Connectivity AMPLIMITE .050 III series (5787082-5, 5787170-5, 787082-5) offers functional substitution with D-type connector styling and female socket configuration. These parts maintain the 50-position, 2-row receptacle architecture with board lock and shielding. Part 5787170-5 and 5787082-5 are ROHS3 compliant active products. Part 787082-5 carries REACH Affected status and is not RoHS applicable, limiting its use in new designs requiring regulatory compliance.

The TE Connectivity CHAMP .050 II series part 5178238-7 provides an alternative with board-side flange mounting and reduced contact finish thickness (11.8µin versus 30.0µin). This part is ROHS3 compliant and active, though it lacks the board lock feature present in the original part.

For new designs, prioritize active products with ROHS3 compliance: 3M 10250-55H3PC (highest inventory at 35,497 units), 3M N10250-52E2PC (3,483 units), or TE Connectivity 5178238-7 (200,200 units). Flange feature specifications (2-56, M2.6, or 4-40) must align with mechanical mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 10250 series directly replace the Molex 0015876043?

A: The 3M 10250 series maintains the critical electrical and mechanical parameters: 50 positions, 2 rows, receptacle type, through-hole right-angle solder termination, outer shroud contacts, board lock, shielding, and gold contact finish. Panel mount capability in the 3M parts does not prevent through-hole board mounting. Flange specifications differ (M2.6 or 4-40 versus 2-56), requiring mechanical design verification for mounting hole compatibility.

Q: What is the difference between the 3M 10250-55F3PC, 10250-55G3PC, and 10250-55H3PC?

A: These parts differ in flange feature specifications and packaging. The 10250-55F3PC features M2.6 flange (Box packaging), 10250-55G3PC features M2.6 flange (Box packaging), and 10250-55H3PC features 4-40 flange with latchblocks (Tray packaging). All three maintain identical electrical specifications and are active products with RoHS compliance.

Q: Are TE Connectivity D-type connectors compatible with the Molex outer shroud design?

A: TE Connectivity AMPLIMITE .050 III series parts (5787082-5, 5787170-5, 787082-5) use D-type connector styling with female sockets rather than outer shroud contacts. While they maintain 50-position, 2-row receptacle configuration with solder termination and shielding, the different connector style may require mechanical and electrical interface verification before substitution.

Q: Which substitute part has the highest inventory availability?

A: TE Connectivity 5178238-7 has the highest inventory at 200,200 units. Among 3M alternatives, 10250-55H3PC offers 35,497 units. For the original Molex part, 769 units remain in stock.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Most substitute parts are RoHS compliant or ROHS3 compliant. Exception: TE Connectivity 787082-5 is not RoHS applicable and carries REACH Affected status, making it unsuitable for applications requiring regulatory compliance. For new designs, select from ROHS3 compliant alternatives: 3M 10250-55H3PC, 3M N10250-52E2PC, TE Connectivity 5787170-5, 5787082-5, or 5178238-7.

Q: What is the significance of flange feature specifications (2-56, M2.6, 4-40)?

A: Flange features define the mechanical mounting interface. The original Molex 0015876043 uses 2-56 screw specification. Substitute parts use M2.6 metric or 4-40 UNC specifications. Selection depends on PCB mounting hole sizing and mechanical design requirements. Verify flange compatibility with your board layout before substitution.

Q: Can the 3M N10250-5242PC be used as a substitute?

A: The 3M N10250-5242PC maintains 50-position receptacle configuration with through-hole right-angle solder termination and 4-40 flange specification. However, it lacks the board lock feature present in the original part, providing only shielding. This may be acceptable depending on application requirements for connector retention.
