Substitute Part Grouping Explanation

Substitution of the Molex 0702462021 is determined by strict equivalence across the following parameters: connector type (header), contact type (male pin), number of positions (20), number of rows (2), pitch (2.54mm), row spacing (2.54mm), mounting type (through hole), termination method (solder), and shrouding configuration (shrouded 4-wall). Parts meeting these criteria are classified as direct equivalents. Parts with variations in mounting orientation (right-angle vs. vertical), position count, or contact post finish are classified as functional alternatives with noted design considerations.

Engineering Selection Recommendations

Direct Equivalents (Vertical Orientation, 20 Positions):

The Molex 0702462001 serves as the primary direct equivalent, offering identical mechanical and electrical specifications with the advantage of active product status and ROHS3 compliance. This part represents the most straightforward replacement path for the obsolete 0702462021.

The TE Connectivity AMP-Latch series (103308-5, 103309-5, 5103308-5, 5103309-5, 5104338-4) provides functionally equivalent alternatives with active status. Parts 5103308-5 and 5103309-5 offer ROHS3 compliance, while 5104338-4 features kinked pin termination for enhanced mechanical retention. The 103308-5 and 103309-5 variants maintain tin-lead post finish consistent with legacy designs.

The 3M 30320-6002HB connector delivers ROHS3 compliance with gold post finish across all contact surfaces, supporting extended operating temperature range (-55°C to 105°C) and higher current rating (1A per contact).

The Amphenol ICC 52601-G20-4LF (Quickie™ series) provides RoHS compliance with phosphor bronze contact material and optional GXT™ gold finish enhancement.

Functional Alternatives (Design Variations):

The HARTING 09185206321 offers right-angle mounting orientation with identical 20-position, 2.54mm pitch configuration. This variant is suitable for applications requiring perpendicular PCB-to-cable routing.

The HARTING 09185265913 provides 26-position configuration at 2.54mm pitch with right-angle mounting. This part accommodates designs requiring additional contact positions while maintaining pitch compatibility.

Compliance Considerations:

For applications requiring RoHS3 compliance, select from: Molex 0702462001, 3M 30320-6002HB, TE Connectivity 5103308-5, 5103309-5, 5104338-4, Amphenol ICC 52601-G20-4LF, or HARTING variants.

For legacy designs maintaining tin-lead post finish, TE Connectivity 103308-5 and 103309-5 preserve original contact metallurgy while offering active product status.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702462021 be directly replaced with the 0702462001?

A: Yes. The 0702462001 is a direct equivalent with identical connector type, position count, pitch, mounting configuration, and shrouding. The primary differences are active product status and ROHS3 compliance. The post finish changes from tin-lead to tin, which is compatible with standard solder reflow processes.

Q: What is the difference between vertical and right-angle mounting options?

A: Vertical mounting (0702462021, 0702462001, TE Connectivity series, 3M, Amphenol ICC) positions the mating interface perpendicular to the PCB surface for cable connection. Right-angle mounting (HARTING 09185206321, 09185265913) orients the mating interface parallel to the PCB surface. Selection depends on physical layout constraints and cable routing requirements.

Q: Are TE Connectivity AMP-Latch parts (103308-5, 103309-5) compatible with the original Molex design?

A: Yes, for mechanical and electrical compatibility. Both parts maintain 20 positions, 2.54mm pitch, 2-row configuration, through-hole vertical mounting, and push-pull fastening. Contact material differs (brass vs. phosphor bronze), and post finish options vary. Operating temperature range extends to -65°C to 105°C, providing broader environmental capability.

Q: What packaging options are available?

A: The Molex 0702462001 is supplied in tray packaging. TE Connectivity parts 103308-5 and 103309-5 are available in bulk packaging, while 5103308-5, 5103309-5, and 5104338-4 are supplied in tube packaging. Amphenol ICC 52601-G20-4LF uses tray packaging. HARTING variants are supplied in bulk. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Does the 3M 30320-6002HB offer advantages over other equivalents?

A: The 3M part provides ROHS3 compliance, gold finish on both mating and post contacts, 1A per contact current rating specification, and extended operating temperature range (-55°C to 105°C). These characteristics support demanding automotive and industrial applications. Inventory availability (37,362 units) ensures supply continuity.

Q: Can the HARTING 09185265913 (26-position) be used as a substitute for the 20-position requirement?

A: No. The 26-position configuration exceeds the specified 20-position requirement. This part is suitable only for applications requiring additional contact positions while maintaining 2.54mm pitch compatibility.

Q: What is the significance of contact finish thickness specifications?

A: Contact finish thickness determines durability under mating cycles and environmental exposure. The original 0702462021 specifies 15.0µin (0.38µm) mating finish and 74.8µin (1.90µm) post finish. Equivalent parts maintain these specifications or provide enhanced thickness (30.0µin mating finish in some variants), extending contact life and improving corrosion resistance.

Q: Are there differences in insulation material between substitutes?

A: Yes. The original uses standard PBT. The Molex 0702462001 specifies glass-filled PBT. TE Connectivity parts use unspecified insulation material or polyphthalamide (PPA) glass-filled in the 5104338-4 variant. 3M uses glass-filled polyester/PBT blend. Material selection affects mechanical strength, thermal stability, and flame rating compliance (all maintain UL94 V-0).
