Engineering Selection Recommendations

Primary Recommendation - Molex 0702472051: The Molex 0702472051 is the direct series equivalent within the C-Grid 70247 family. It maintains identical mechanical and electrical specifications to the 0702472001 while offering ROHS3 compliance and active product status. The only material difference is contact material (Phosphor Bronze vs. Brass), which does not affect functional compatibility. This part is recommended for direct replacement in new designs and production continuity.

Secondary Recommendation - HARTING SEK Series (09185205323, 09185206323, 09185207323, 09195206323): HARTING SEK series connectors provide cross-manufacturer substitution with ROHS3 compliance and active availability. These parts maintain the critical 20-position, 2-row, 2.54mm pitch configuration with shrouded 4-wall construction and solder termination. Dimensional variations exist in contact length and insulation height; however, these remain within acceptable mechanical tolerances for standard PCB mounting applications. Operating temperature range extends to -55°C ~ 125°C, providing enhanced thermal performance. Fastening type differs (Latch Holder vs. Push-Pull), which may require connector housing compatibility verification.

Tertiary Recommendation - TE Connectivity 103310-5: The TE Connectivity AMP-Latch 103310-5 provides cross-manufacturer substitution with identical push-pull fastening and contact material (Brass). This part maintains active product status and offers specified current rating of 1A per contact. However, RoHS non-compliance status aligns with the original part specification. This option is suitable for applications where RoHS compliance is not required and existing AMP-Latch connector infrastructure is present.

Compliance Consideration: For applications requiring RoHS3 compliance, Molex 0702472051 or HARTING SEK series parts are mandatory selections. The original 0702472001 and TE Connectivity 103310-5 are RoHS non-compliant and unsuitable for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702472051 directly replace the obsolete 0702472001?

A: Yes. The 0702472051 is functionally equivalent with identical pitch (2.54mm), position count (20), row configuration (2), mounting type (through-hole right-angle), shrouding (4-wall), and termination (solder). The contact material difference (Phosphor Bronze vs. Brass) does not affect electrical performance or mechanical compatibility. The primary advantage is ROHS3 compliance and active product status.

Q: What are the key differences between Molex and HARTING substitutes?

A: Molex 0702472051 maintains identical dimensions and contact specifications. HARTING SEK series parts introduce minor dimensional variations: contact length mating increases from 0.240" to 0.242", insulation height increases from 0.350" to 0.366", and fastening type changes from push-pull to latch holder. These variations are mechanically compatible with standard PCB layouts but require connector housing compatibility verification.

Q: Are HARTING parts suitable for automotive applications?

A: HARTING SEK series parts carry ROHS3 compliance and UL94 V-0 flammability rating, meeting automotive electrical standards. Operating temperature range (-55°C ~ 125°C) exceeds typical automotive requirements. Compatibility depends on specific connector housing and mating interface specifications for the target application.

Q: What is the significance of fastening type differences?

A: The original 0702472001 uses push-pull fastening; HARTING substitutes use latch holder fastening. These are distinct mechanical interfaces. Push-pull connectors mate with push-pull receptacles; latch holder connectors mate with latch holder receptacles. Fastening type must match the mating connector housing. Verify mating connector specifications before substitution.

Q: Is the TE Connectivity 103310-5 suitable for new designs?

A: The TE Connectivity 103310-5 is functionally compatible and maintains push-pull fastening identical to the original part. However, RoHS non-compliance status restricts use to applications where RoHS certification is not required. For regulated markets or new production, Molex 0702472051 or HARTING ROHS3-compliant alternatives are required.

Q: How do insulation material differences affect substitution?

A: The original part and Molex 0702472051 use PBT (Polybutylene Terephthalate); HARTING 09195206323 uses PCT (Polycyclohexylenedimethylene Terephthalate). Both materials carry UL94 V-0 flammability rating and are suitable for the specified applications. PCT offers slightly enhanced thermal and chemical resistance; however, both materials are functionally equivalent for standard connector applications.

Q: What packaging options are available?

A: Molex 0702472051 is supplied in tray packaging. HARTING parts are available in bulk or tray configurations depending on specific part number. TE Connectivity 103310-5 is supplied in tube packaging. Packaging selection does not affect electrical or mechanical performance; selection is based on production volume and handling requirements.

Q: Can these parts be used interchangeably in existing assemblies?

A: Mechanical and electrical interchangeability depends on mating connector housing specifications. Verify that the substitute part's fastening type (push-pull vs. latch holder), contact length, and insulation height are compatible with existing receptacle connectors. Dimensional variations may require PCB layout verification for right-angle mounting clearance.
