Engineering Selection Recommendations

Primary Recommendation: Molex 0702461001

The Molex 0702461001 is the direct successor within the same manufacturer's C-Grid 70246 series. It maintains identical electrical and mechanical specifications to the obsolete 0702461021 while offering active product status and ROHS3 compliance. The primary distinction is post-contact finish (tin versus tin-lead), which does not affect functional compatibility. This part provides the lowest risk substitution path with 20,685 units in stock.

Secondary Recommendations: TE Connectivity AMP-Latch Series

TE Connectivity parts 103309-1, 5103309-1, and 5104338-1 provide functional equivalence with active status. Parts 5103309-1 and 5104338-1 offer RoHS compliance. The 103309-1 and 103308-1 variants are RoHS non-compliant. Contact finish thickness on mating surfaces varies (15.0µin to 30.0µin), and post-contact material differs (brass versus phosphor bronze), but these variations remain within acceptable substitution parameters for the specified applications.

Tertiary Recommendation: 3M 30310-6002HB

The 3M 30310-6002HB from the 303 series provides ROHS3 compliance and active status with 18,800 units available. Contact length specifications differ slightly (0.236" mating versus 0.240" on main part), and post-contact finish is gold rather than tin-lead. Operating temperature range extends to -55°C to 105°C.

Alternative for Right-Angle Mounting: HARTING 09195106323740

The HARTING 09195106323740 provides functional equivalence with right-angle mounting geometry, suitable for applications requiring modified PCB layout. This part features latch holder fastening instead of push-pull and operates across -55°C to 125°C. Insulation color is beige rather than black. This substitution applies only when right-angle orientation is acceptable.

Amphenol ICC Quickie™ Series: 52601-G10-4LF

The Amphenol ICC 52601-G10-4LF offers RoHS compliance and active status with 3,000 units in stock. Contact material is phosphor bronze, matching the main part. Contact length specifications differ (0.230" mating versus 0.240"), and post-contact finish is tin. This part is suitable for applications where Amphenol ICC compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702461001 directly replace the obsolete 0702461021?

A: Yes. The 0702461001 maintains identical pitch (2.54mm), position count (10), row configuration (2 rows), mounting type (through hole), shrouding (4-wall), and fastening mechanism (push-pull). The post-contact finish differs (tin versus tin-lead), which does not affect electrical or mechanical compatibility. This is the recommended direct replacement.

Q: What is the significance of RoHS compliance in substitute selection?

A: RoHS compliance status indicates regulatory conformance for lead content and hazardous substances. The main part 0702461021 is RoHS non-compliant. Active substitutes include both compliant (0702461001, 30310-6002HB, 5103309-1, 5104338-1, 52601-G10-4LF) and non-compliant (103308-1, 103309-1) options. Selection depends on end-application regulatory requirements.

Q: Are TE Connectivity AMP-Latch parts interchangeable with Molex C-Grid parts?

A: Functional interchangeability exists for the specified electrical and mechanical parameters. Both series maintain 2.54mm pitch, 10-position, 2-row configuration, through-hole mounting, and push-pull fastening. Contact material differs (brass in TE Connectivity versus phosphor bronze in Molex), and contact finish specifications vary. These differences do not prevent substitution within the defined parameter set.

Q: When should the HARTING 09195106323740 right-angle variant be selected?

A: The HARTING part applies only when PCB layout requires right-angle connector orientation instead of vertical. The fastening mechanism differs (latch holder versus push-pull), and operating temperature range extends to 125°C. This substitution requires PCB redesign and is not a direct drop-in replacement.

Q: What packaging options are available for these substitutes?

A: Molex 0702461001 is supplied in bulk packaging. TE Connectivity parts 5103308-1, 5103309-1, and 5104338-1 are supplied in tray packaging. Amphenol ICC 52601-G10-4LF is supplied in tray packaging. 3M 30310-6002HB is supplied in bulk packaging. Packaging selection affects handling and storage procedures but does not affect component functionality.

Q: Do contact finish variations affect electrical performance?

A: Contact finish specifications (gold thickness, tin-lead versus tin) are provided in the parameter set. Variations in finish thickness (15.0µin to 30.0µin on mating surfaces) and post-contact material (tin, tin-lead, or gold) remain within acceptable ranges for the specified applications. Electrical performance is not affected by these variations within the defined parameter boundaries.

Q: Is the 3M 30310-6002HB suitable for automotive applications?

A: The 3M 30310-6002HB is specified for general purpose applications. The main part 0702461021 lists automotive as an application. The 3M part does not explicitly list automotive in the provided specifications, though it maintains all critical mechanical and electrical parameters. Application suitability should be confirmed against specific automotive qualification requirements.
