Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSQ-120-22-S-S is determined by strict alignment of the following parameters:

• Connector type: Receptacle
• Number of positions: 20
• Mating pitch: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination method: Solder
• Fastening type: Push-pull
• Contact finish (mating): Gold
• Contact type: Forked
• Insulation color: Black
• Flammability rating: UL94 V-0

The substitute part 929850-01-20-RB (3M) meets all these core parameters, establishing it as an equivalent component for the SSQ-120-22-S-S in applications where these specifications are required.

Parameter Comparison

Engineering Selection Recommendations

Both the SSQ-120-22-S-S and 929850-01-20-RB are active production components with equivalent core specifications. Selection between these parts should be based on:

• Availability: The 929850-01-20-RB has 1187 units in stock compared to 819 units for the SSQ-120-22-S-S
• Compliance: Both parts meet UL94 V-0 flammability requirements and are RoHS compliant
• Regulatory classification: Both parts carry EAR99 export classification and share the same HTSUS code
• Mechanical fit: Both connectors feature identical mating pitch, mounting type, and fastening mechanism

The 929850-01-20-RB may be selected as a direct substitute when the SSQ-120-22-S-S is unavailable, provided that the differences in insulation height (0.325" vs. 0.335"), contact post length (0.125" vs. 0.194"), operating temperature range (-40°C to 105°C vs. -55°C to 125°C), and voltage rating (1500V vs. 465VAC/655VDC) are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 929850-01-20-RB be used as a direct replacement for the SSQ-120-22-S-S?

A: Yes, the 929850-01-20-RB meets all core substitution criteria: 20-position receptacle, 0.100" pitch, through-hole solder termination, push-pull fastening, gold mating contacts, forked contact type, and UL94 V-0 flammability rating. Physical and electrical differences exist in insulation height, contact post length, operating temperature, and voltage rating; verify these parameters against your application requirements before substitution.

Q: What are the key differences between these two connectors?

A: The primary differences are insulation height (SSQ-120-22-S-S: 0.335" vs. 929850-01-20-RB: 0.325"), contact post length (SSQ-120-22-S-S: 0.194" vs. 929850-01-20-RB: 0.125"), operating temperature range (SSQ-120-22-S-S: -55°C to 125°C vs. 929850-01-20-RB: -40°C to 105°C), voltage rating (SSQ-120-22-S-S: 465VAC/655VDC vs. 929850-01-20-RB: 1500V), and current rating (929850-01-20-RB: 2A specified). Insulation material also differs: SSQ uses Liquid Crystal Polymer (LCP) while 929850-01-20-RB uses PCT/Polyester/Glass Filled.

Q: Are both connectors RoHS compliant?

A: Yes. The SSQ-120-22-S-S is ROHS3 compliant, and the 929850-01-20-RB is RoHS compliant. Both meet environmental and hazardous substance restrictions.

Q: What is the mating pitch for these connectors?

A: Both connectors feature a 0.100" (2.54mm) mating pitch, enabling mechanical and electrical compatibility with standard 0.1" spaced connector systems.

Q: Can these connectors be used in high-temperature applications?

A: The SSQ-120-22-S-S supports operating temperatures from -55°C to 125°C, making it suitable for extended temperature range applications. The 929850-01-20-RB operates from -40°C to 105°C. Select the SSQ-120-22-S-S for applications requiring the full -55°C to 125°C range.
