Engineering Selection Recommendations

TE Connectivity 5646357-1 (Direct Substitute)

The 5646357-1 is a direct substitute within the TE Connectivity Z-PACK series. This part maintains identical electrical specifications (1.5 A current rating, 750Vrms voltage rating) and mechanical configuration. The primary distinction is RoHS compliance status: the 5646357-1 is RoHS Compliant, whereas the 646357-1 is RoHS Non-Compliant. Selection of the 5646357-1 is appropriate for applications subject to RoHS regulatory requirements. Inventory availability is higher at 1469 units.

HARTING 17122502201 (Alternative Substitute)

The 17122502201 is a functionally equivalent alternative from HARTING's har-bus® HM series. This connector maintains the same position count, pitch, row configuration, and operating temperature range. The current rating is specified at 1 A, which is lower than the 646357-1 specification of 1.5 A. The voltage rating is not specified in available documentation. This part is ROHS3 Compliant and REACH Unaffected. Selection of the 17122502201 is appropriate for applications where the 1 A current rating is sufficient and HARTING connector ecosystem integration is required.

Selection Criteria:

• For RoHS-compliant applications within TE Connectivity ecosystem: select 5646357-1
• For applications requiring HARTING connector compatibility: select 17122502201
• For applications with no RoHS requirement and TE Connectivity preference: 646357-1 remains valid
• For applications requiring 1.5 A current rating: 646357-1 or 5646357-1 only

Frequently Asked Questions (FAQ)

Q: Can the 5646357-1 be used as a direct replacement for the 646357-1?

A: Yes. The 5646357-1 is electrically and mechanically identical to the 646357-1. Both connectors feature 250 positions at 0.079" pitch, 1.5 A current rating, and 750Vrms voltage rating. The primary difference is RoHS compliance status. Substitution is valid for all applications where the 646357-1 was originally specified.

Q: What is the current rating difference between the 646357-1 and the HARTING 17122502201?

A: The 646357-1 is rated for 1.5 A, while the 17122502201 is rated for 1 A. Applications requiring current levels between 1 A and 1.5 A must use the 646357-1 or 5646357-1. Applications with maximum current requirements of 1 A or less can use the 17122502201.

Q: Are all three connectors compatible with the same PCB footprint?

A: Yes. All three connectors share identical mechanical specifications: 250 positions, 0.079" (2.00mm) pitch, 8 + 2 row configuration, and through-hole press-fit termination. PCB footprints designed for the 646357-1 accommodate the 5646357-1 and 17122502201 without modification.

Q: What is the difference between RoHS Non-Compliant and RoHS Compliant status?

A: RoHS Compliance indicates the connector meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The 646357-1 is RoHS Non-Compliant, while the 5646357-1 is RoHS Compliant and the 17122502201 is ROHS3 Compliant. Selection depends on regulatory requirements applicable to the end application and target market.

Q: Can the 17122502201 be used in applications originally designed for the 646357-1?

A: The 17122502201 is mechanically and electrically compatible with the 646357-1 for applications where the 1 A current rating is sufficient. If the application requires the full 1.5 A current rating of the 646357-1, the 17122502201 is not suitable. Voltage rating specifications for the 17122502201 are not provided; applications with specific voltage requirements should reference the 646357-1 or 5646357-1 specifications.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: All three connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.

Q: Are there packaging differences between these three parts?

A: All three connectors are supplied in tube packaging. Inventory quantities differ: 646357-1 (745 units), 5646357-1 (1469 units), and 17122502201 (1195 units).
