Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-150-21-G-D is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 100
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Type: Forked
• Contact Finish - Mating: Gold
• Voltage Rating: 465VAC, 655VDC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as direct substitutes. Variations in internal part numbering (such as the suffix designation) do not affect functional equivalence when all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both SSQ-150-21-G-D and SSQ-150-01-G-D are Active status products from Samtec Inc. and maintain identical electrical and mechanical specifications. Both connectors are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial applications.

Selection between these parts may be based on inventory availability. The SSQ-150-01-G-D currently maintains higher stock levels (3302 pcs) compared to SSQ-150-21-G-D (1071 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are SSQ-150-21-G-D and SSQ-150-01-G-D electrically interchangeable?

A: Yes. Both connectors share identical electrical specifications including voltage rating (465VAC, 655VDC), operating temperature range (-55°C ~ 125°C), and contact material composition (Phosphor Bronze with gold plating).

Q: What determines compatibility between these substitute parts?

A: Compatibility is determined by matching connector type (Receptacle), position count (100), mating pitch (0.100"), row configuration (2 rows), mounting method (Through Hole), and termination type (Solder). All these parameters are identical between the two parts.

Q: Can these connectors be used in the same PCB layout?

A: Yes. Both parts have identical mechanical dimensions including insulation height (0.335"), contact length (0.104"), and row spacing (0.100"), ensuring direct PCB footprint compatibility.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8536.69.4040).

Q: What is the difference between the part number suffixes?

A: The suffix designations (-21-G-D versus -01-G-D) represent internal Samtec numbering variations that do not affect functional performance or electrical characteristics when all core parameters remain identical.
