• Electrical Rating: Both rated at 4.7A per contact
• Operating Temperature: Identical -55°C to 125°C range
• Compliance & Standards: Both ROHS3 compliant with UL94 V-0 flammability rating
• Insulation Material: Both use Liquid Crystal Polymer (LCP) with black insulation
• Series & Base Product: Both belong to the SSW series with base product number SSW-120

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-120-23-S-S and SSW-120-03-SM-S are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory Availability: The SSW-120-03-SM-S currently has 986 units in stock compared to 718 units for the SSW-120-23-S-S
• Compliance Status: Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for equivalent applications
• Production Continuity: Both parts are active in the SSW series product line, ensuring long-term availability and supply chain stability

No electrical or mechanical redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Are SSW-120-23-S-S and SSW-120-03-SM-S electrically interchangeable?

A: Yes. Both connectors have identical electrical specifications including 4.7A per contact current rating, operating temperature range of -55°C to 125°C, and contact finish specifications (gold mating, tin post).

Q: Do these connectors have the same physical dimensions?

A: Yes. Both connectors share identical mechanical specifications including 0.100" (2.54mm) pitch, 20-position configuration, 0.335" (8.51mm) insulation height, and 0.394" (10.00mm) contact post length for through-hole mounting.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-120-23-S-S and SSW-120-03-SM-S are ROHS3 compliant and carry UL94 V-0 flammability rating.

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

A: The part numbers differ in their suffix designations (23-S-S versus 03-SM-S), which may indicate internal manufacturing variations or packaging differences. All provided electrical and mechanical parameters are identical.

Q: Can I use SSW-120-03-SM-S as a direct replacement in existing designs?

A: Yes. No PCB layout modifications or design changes are required. The connector maintains the same footprint, pitch, and electrical characteristics for direct substitution.
