Key Parameters

Substitute Part Grouping Explanation

Substitution within the SSW series is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts are 20-position receptacles
• Pitch & Mounting: Identical 0.100" (2.54mm) pitch with surface mount termination
• Contact Configuration: Forked contact design maintained across all variants
• Electrical Performance: Matching 4.7A per contact current rating and operating temperature range
• Material & Compliance: Identical insulation material (LCP), flammability rating (UL94 V-0), and RoHS3 compliance
• Contact Finish: Gold-plated mating surfaces with equivalent thickness specifications

The substitute part SSW-120-22-F-S-VS differs only in fastening mechanism designation within the part number nomenclature while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-120-22-FM-S-VS and SSW-120-22-F-S-VS maintain Active product status with full RoHS3 compliance and identical electrical specifications. Selection between these parts should be based on inventory availability and lead time requirements, as both parts satisfy equivalent functional and compliance criteria for 20-position surface mount receptacle applications.

The SSW-120-22-F-S-VS currently maintains higher inventory levels (1020 Pcs vs. 796 Pcs), which may provide supply chain advantages for high-volume production schedules.

Frequently Asked Questions (FAQ)

Q: Are SSW-120-22-FM-S-VS and SSW-120-22-F-S-VS electrically interchangeable?

A: Yes. Both parts are 20-position receptacles with identical pitch (0.100"), contact configuration (forked), current rating (4.7A per contact), and operating temperature range (-55°C to 125°C). Electrical performance is equivalent.

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

A: The part number nomenclature differs in the fastening mechanism designation (FM vs. F), but both parts maintain identical electrical and mechanical specifications within the SSW series connector family.

Q: Can I use SSW-120-22-F-S-VS as a direct replacement for SSW-120-22-FM-S-VS?

A: Yes, for applications requiring a 20-position surface mount receptacle connector with 0.100" pitch and gold-plated contacts. Both parts are RoHS3 compliant and rated for -55°C to 125°C operation.

Q: Are there any packaging or MSL differences I should consider?

A: Both parts are supplied in Tube packaging. The main part (SSW-120-22-FM-S-VS) carries MSL Level 1 (Unlimited), while the substitute (SSW-120-22-F-S-VS) is listed as Not Applicable. MSL Level 1 indicates no moisture sensitivity restrictions for standard manufacturing environments.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching connector type, position count, pitch, mounting method, contact type, contact finish, current rating, operating temperature range, insulation material, and compliance certifications. All these parameters are identical between the two parts.
