Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-120-23-F-D is determined by strict alignment of the following parameters:

• Connector type (Receptacle)
• Position count (40 positions)
• Mating pitch (0.100" / 2.54mm)
• Row configuration (2 rows with 0.100" spacing)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish on mating surface (Gold)
• Voltage rating (465VAC, 655VDC minimum)
• Operating temperature range (-55°C ~ 125°C minimum)
• Regulatory compliance (ROHS3 Compliant)

The SSQ-120-03-F-D meets all substitution criteria, sharing identical electrical and mechanical specifications with the main part number while maintaining the same series designation and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-120-23-F-D and SSQ-120-03-F-D maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on inventory availability and supply chain considerations. The SSQ-120-23-F-D currently maintains 991 units in stock, while the SSQ-120-03-F-D maintains 707 units. Both parts are functionally equivalent for applications requiring 40-position rectangular receptacle connectors with 0.100" pitch, through-hole mounting, and gold-plated contacts rated for 465VAC / 655VDC operation across the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are SSQ-120-23-F-D and SSQ-120-03-F-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, including 40-position configuration, 0.100" mating pitch, 2-row layout with 0.100" row spacing, 0.335" insulation height, and 0.394" contact post length. Through-hole mounting footprints are identical.

Q: Do these parts have the same electrical ratings?

A: Yes. Both parts are rated for 465VAC and 655VDC with identical operating temperature range of -55°C to 125°C. Contact finish specifications, including 3.00µin gold plating on mating surfaces and tin plating on posts, are identical.

Q: Are there compliance differences between these part numbers?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, UL94 V-0 flammability rating, and EAR99 ECCN classification. Moisture sensitivity level is Not Applicable for both.

Q: What determines substitution eligibility for SSQ-120 series connectors?

A: Substitution is valid when the following parameters match: connector type (Receptacle), position count (40), mating pitch (0.100"), row configuration (2 rows at 0.100" spacing), mounting type (Through Hole), termination method (Solder), and contact finish (Gold). Voltage and temperature ratings must meet or exceed the original specification.

Q: Can I use these connectors in high-temperature applications?

A: Both parts operate across -55°C to 125°C. Applications requiring operation beyond this range require alternative connector selection.
