Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC-1645 is determined by strict equivalence across the following critical parameters:

• Manufacturer: Hirose Electric Co Ltd
• Series: Sumicon 1600
• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 45
• Number of Rows: 3
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Resin
• Features: Flange
• Moisture Sensitivity Level: 1 (Unlimited)

The SC-1645(10) variant meets all substitution criteria. The primary difference is the color specification (black versus blue) and product status (active versus obsolete), neither of which affects electrical or mechanical compatibility within the Sumicon 1600 series architecture.

Parameter Comparison

Engineering Selection Recommendations

The SC-1645(10) is the direct substitute for the obsolete SC-1645. Both parts share identical electrical and mechanical specifications within the Sumicon 1600 series. The SC-1645(10) offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The RoHS compliance certification of SC-1645(10) provides enhanced environmental and regulatory alignment for applications subject to RoHS directives. Color differentiation (black versus blue) is a cosmetic distinction that does not impact functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can SC-1645(10) be used as a direct replacement for SC-1645?

A: Yes. Both parts are manufactured by Hirose Electric Co Ltd within the Sumicon 1600 series and share identical specifications for connector type, contact configuration, position count, row arrangement, mounting method, termination type, and insulation material. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the color difference between SC-1645 and SC-1645(10)?

A: Color is a cosmetic specification that does not affect electrical performance, mechanical fit, or contact compatibility. Selection between blue and black housings should be based on application-specific visual identification or system design requirements only.

Q: Why is SC-1645 listed as obsolete?

A: Obsolescence indicates that the part is no longer in active production. SC-1645(10) is the active equivalent and is recommended for new designs and ongoing procurement.

Q: Does the RoHS compliance of SC-1645(10) affect compatibility?

A: RoHS compliance indicates adherence to environmental and hazardous substance restrictions. This certification does not alter the electrical or mechanical compatibility of SC-1645(10) with systems designed for SC-1645. RoHS compliance is beneficial for applications subject to environmental regulations.

Q: Are contacts included with these connector housings?

A: No. Both SC-1645 and SC-1645(10) are housings only. Contacts must be procured separately and installed via crimp termination.

Q: What packaging options are available?

A: SC-1645 is available in standard packaging. SC-1645(10) is supplied in bulk packaging, which may affect procurement quantities and logistics considerations.
