Parameter Comparison

Engineering Selection Recommendations

Both the SSW-121-22-S-D and SSW-121-02-S-D are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: The SSW-121-22-S-D has higher inventory (1128 units) compared to SSW-121-02-S-D (780 units).
• Compliance: Both parts are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040).
• Moisture Sensitivity: The SSW-121-02-S-D specifies MSL 1 (Unlimited), while the main part does not specify MSL, indicating no moisture sensitivity constraints for either part.
• Functional Equivalence: All critical parameters match exactly, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can SSW-121-02-S-D be used as a direct replacement for SSW-121-22-S-D?

A: Yes. Both parts share identical electrical and mechanical specifications, including 42 positions, 0.100" pitch, through-hole solder termination, gold-plated mating contacts, and operating temperature range of -55°C to 125°C. Direct substitution is supported without circuit or PCB layout changes.

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

A: Substitution compatibility is determined by: number of positions (42), mating pitch (0.100"), number of rows (2), row spacing (0.100"), connector type (receptacle), mounting type (through hole), termination method (solder), contact finish (gold), operating temperature range (-55°C to 125°C), insulation material (LCP), and flammability rating (UL94 V-0). All these parameters must match exactly.

Q: Are there any differences in packaging or handling between these parts?

A: Both parts are supplied in bulk packaging. The SSW-121-02-S-D specifies MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling procedures for through-hole connectors apply to both parts.

Q: What is the current rating for these connectors?

A: Both parts are rated for 4.7A per contact, supporting the same electrical load capacity in applications.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-121-22-S-D and SSW-121-02-S-D are ROHS3 compliant and meet the same regulatory requirements for hazardous substance restrictions.
