Engineering Selection Recommendations

Molex 0702462401 is the primary direct substitute. This part maintains identical mechanical and electrical specifications within the C-Grid 70246 series while carrying active product status. The transition from tin-lead to tin post finish and the addition of glass-filled PBT insulation material represent standard manufacturing evolution. ROHS3 compliance status addresses regulatory requirements absent in the obsolete 0702462421.

TE Connectivity 1-5103308-3 and 5104338-5 (AMP-Latch series) provide cross-manufacturer alternatives with active status and ROHS3 compliance. Both maintain the 24-position, 2.54mm pitch configuration with push-pull fastening. The 5104338-5 incorporates kinked pin termination and polyphthalamide insulation, offering enhanced mechanical retention. Operating temperature range extends to -65°C, supporting broader environmental applications.

3M N2524-6003-RB delivers equivalent functionality within the 2500 series. This part specifies 1.75A current rating and -55°C to 105°C operating range. The copper alloy contact material with enhanced tin post finish thickness (200.0µin) provides increased durability for high-cycle mating applications.

3M N2524-6005EB differs in termination method (wire wrap vs. solder) and post finish (gold). This variant suits applications requiring wire-wrap assembly processes and is not recommended as a direct solder-termination substitute.

Sullins SBH11-PBPC-D12-ST-BK offers the highest current rating (3A per contact) with gold post finish and -40°C to 105°C operating range. This part accommodates multiple mated stacking heights (9.65mm, 11.2mm, 13.35mm, 18.35mm), enabling flexible connector stack configurations.

For designs requiring RoHS compliance and active product support, Molex 0702462401 is the preferred selection. For applications demanding extended temperature range or higher current capacity, TE Connectivity or 3M alternatives provide suitable options.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702462401 directly replace the obsolete 0702462421 without PCB redesign?

A: Yes. Both parts share identical mechanical footprints, pitch spacing (0.100"), row configuration (2 rows of 24 positions), shrouding geometry, and through-hole mounting. The 0702462401 maintains full pin-to-pin compatibility. Post finish composition change (tin-lead to tin) does not affect solder joint formation or electrical performance.

Q: What is the primary difference between Molex 0702462401 and TE Connectivity 1-5103308-3?

A: Both maintain 24-position, 2.54mm pitch header configuration with identical mating contact geometry. Primary differences include contact material (phosphor bronze vs. brass), insulation material composition, and operating temperature specification (-65°C to 105°C for TE vs. unspecified for Molex). Mechanical footprint compatibility is maintained.

Q: Are the 3M N2524-6003-RB and N2524-6005EB interchangeable?

A: No. These parts differ in termination method. The N2524-6003-RB uses solder termination; the N2524-6005EB uses wire wrap. Selection depends on assembly process requirements. Both maintain identical mating interface geometry and position count.

Q: Does the Sullins SBH11-PBPC-D12-ST-BK support multiple stacking heights?

A: Yes. This part accommodates mated stacking heights of 9.65mm, 11.2mm, 13.35mm, and 18.35mm, enabling connector stack configurations. Other substitutes in this list do not specify multiple stacking height options.

Q: Which substitute part offers the highest current rating?

A: The Sullins SBH11-PBPC-D12-ST-BK specifies 3A per contact. The 3M N2524-6003-RB provides 1.75A per contact. TE Connectivity parts specify 1A per contact. The original Molex 0702462421 does not specify current rating.

Q: Are all substitute parts RoHS compliant?

A: The original Molex 0702462421 is RoHS non-compliant. All active substitute parts (0702462401, 1-5103308-3, 5104338-5, N2524-6003-RB, N2524-6005EB, SBH11-PBPC-D12-ST-BK) carry RoHS or ROHS3 compliance status, meeting current regulatory requirements.

Q: What packaging formats are available for these substitutes?

A: Molex 0702462401 ships in trays. TE Connectivity parts (1-5103308-3, 5104338-5) are supplied in tubes. 3M N2524-6003-RB is bulk packaged; N2524-6005EB packaging is unspecified. Sullins SBH11-PBPC-D12-ST-BK is tray packaged. Packaging selection may affect procurement lead times and handling requirements.
