Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-120-24-G-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (40)
• Pitch specification (0.100" / 2.54mm)
• Row configuration (2 rows)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact configuration (Forked)
• Contact finish (Gold)
• Voltage rating (465VAC, 655VDC)
• Operating temperature range (-55°C ~ 125°C)
• Flammability rating (UL94 V-0)
• RoHS compliance (ROHS3)

The SSQ-120-04-G-D meets all substitution criteria and is classified as a direct equivalent part within the SSQ series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-120-24-G-D and SSQ-120-04-G-D are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The SSQ-120-04-G-D currently has higher inventory availability (1644 pcs vs. 709 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are SSQ-120-24-G-D and SSQ-120-04-G-D fully interchangeable?

A: Yes. Both parts are identical in electrical and mechanical specifications, including connector type, position count, pitch, row configuration, mounting method, termination type, contact finish, voltage rating, and operating temperature range. They are direct substitutes within the SSQ series.

Q: What determines substitution eligibility for rectangular connectors in the SSQ series?

A: Substitution is based on equivalence across connector type, position count, pitch specification, row configuration, mounting method, termination type, contact configuration, contact finish, voltage rating, operating temperature range, and flammability rating. All these parameters must match exactly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SSQ-120-24-G-D and SSQ-120-04-G-D are ROHS3 compliant and carry UL94 V-0 flammability certification. They share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

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

A: Both parts are rated for operating temperatures from -55°C to 125°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the difference between the two part numbers?

A: The part numbers SSQ-120-24-G-D and SSQ-120-04-G-D differ only in their suffix designation within the SSQ-120 base product line. All functional and electrical parameters are identical.
