Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-5645502-1 is the direct equivalent for the obsolete 1-645502-1. Selection of the substitute is based on the following engineering criteria:

Product Status: The original part 1-645502-1 carries an obsolete designation, which restricts long-term procurement viability. The substitute 1-5645502-1 maintains active product status, ensuring continued availability and manufacturer support.

Compliance and Certifications: The substitute part 1-5645502-1 is RoHS Compliant, whereas the original part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in many jurisdictions and end-use applications.

Electrical and Mechanical Compatibility: All functional parameters remain identical between the original and substitute parts. The pin diameter acceptance range, solder termination, connector geometry, contact material composition, and gold finish specifications are preserved without deviation.

Operating Temperature Specification: The substitute part provides a defined operating temperature range of -65°C to 126°C, whereas the original part does not specify this parameter. This additional specification data supports thermal design validation in applications requiring temperature performance documentation.

Packaging and Availability: The substitute part is available in Cut Tape (CT) packaging with significantly higher inventory levels (11,813 pieces versus 913 pieces), supporting both prototype and production-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Are the 1-645502-1 and 1-5645502-1 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including overall length (0.260"), socket depth (0.210"), mounting hole diameter (0.069"), and flange diameter (0.088").
