Key Parameters

Substitute Part Grouping Explanation

Substitution between 646955-1 and 5646955-1 is based on functional and electrical equivalence within the UPM series. Both parts share identical core specifications: 5-position male blade header configuration, board edge through-hole right-angle mounting, press-fit termination, gold or gold-palladium contact finish, gray color, and UL94 V-0 flammability rating.

The primary differences between these parts are packaging format and compliance certifications. The 646955-1 is supplied in bulk packaging, while the 5646955-1 is supplied in tube packaging. The 5646955-1 provides additional operational specifications including operating temperature range (-55°C to 125°C) and voltage rating (250V), and carries ROHS3 compliance certification. The 646955-1 is RoHS non-compliant and REACH affected, whereas 5646955-1 is ROHS3 compliant and REACH unaffected.

Substitution is valid when packaging format flexibility is available and compliance requirements align with application specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between 646955-1 and 5646955-1 is determined by compliance and packaging requirements specific to the application.

Select 646955-1 when bulk packaging is required and RoHS non-compliance is acceptable for the application. This part is suitable for applications without regulatory restrictions on hazardous substances.

Select 5646955-1 when ROHS3 compliance and REACH unaffected status are required. This part is suitable for applications subject to European Union environmental regulations or customer specifications mandating RoHS3 certification. The tube packaging format of 5646955-1 provides alternative handling and storage options. The 5646955-1 provides explicit operating temperature range (-55°C to 125°C) and voltage rating (250V) specifications, which are not documented for 646955-1.

Both parts maintain identical functional specifications for connector geometry, termination method, contact configuration, and flammability rating. Current rating is specified as 10A for 646955-1; current rating is not specified for 5646955-1.

Frequently Asked Questions (FAQ)

Q: Are 646955-1 and 5646955-1 electrically equivalent?

A: Both parts share identical connector specifications: 5-position male blade header, board edge through-hole right-angle mounting, press-fit termination, gold or gold-palladium contact finish, and UL94 V-0 flammability rating. The primary differences are packaging format (bulk versus tube) and compliance certifications (RoHS and REACH status).

Q: What is the difference in packaging between these parts?

A: The 646955-1 is supplied in bulk packaging, while the 5646955-1 is supplied in tube packaging. Packaging selection depends on handling, storage, and inventory management requirements for the application.

Q: Which part should be selected for RoHS-compliant applications?

A: The 5646955-1 carries ROHS3 compliance certification and is REACH unaffected. The 646955-1 is RoHS non-compliant and REACH affected. Applications requiring RoHS3 compliance must use 5646955-1.

Q: Are the operating temperature ranges the same for both parts?

A: The 5646955-1 specifies an operating temperature range of -55°C to 125°C. The 646955-1 does not provide an operating temperature specification in the available documentation.
