Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-138-22-S-D is determined by the following critical parameters:

• Connector Type & Position Count: Must be receptacle with 76 positions
• Pitch & Row Configuration: 0.100" (2.54mm) mating pitch with 2-row layout and 0.100" row spacing
• Mounting & Termination: Through-hole solder termination required
• Contact Specifications: Forked contact type with gold mating finish (30.0µin thickness) and tin post finish
• Electrical Performance: 4.7A per contact current rating
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, operating range -55°C to 125°C
• Mechanical Dimensions: Insulation height 0.335" (8.51mm), contact post length 0.194" (4.93mm)

The SSW-138-02-S-D meets all these criteria and qualifies as a direct substitute within the SSW series.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-138-22-S-D and SSW-138-02-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-138-02-S-D offers higher inventory (841 units vs. 720 units), providing improved supply chain flexibility.
• Compliance: Both parts meet ROHS3 requirements and UL94 V-0 flammability standards, suitable for regulated applications.
• Interchangeability: The parts are mechanically and electrically interchangeable within the SSW series, with no design modifications required for substitution.

Frequently Asked Questions (FAQ)

Q: Are SSW-138-22-S-D and SSW-138-02-S-D fully interchangeable?

A: Yes. Both connectors share identical electrical ratings (4.7A per contact), mechanical dimensions (76 positions, 0.100" pitch, 2-row configuration), contact finishes (gold mating, tin post), and environmental specifications (-55°C to 125°C operating range, UL94 V-0). They are direct substitutes within the SSW series.

Q: What determines substitution eligibility for SSW rectangular connectors?

A: Substitution requires matching position count, mating pitch, row configuration, mounting type, termination method, contact finish specifications, and current rating. Deviations in any of these parameters disqualify a part as a substitute.

Q: Can I use these connectors in high-temperature applications?

A: Both parts operate within -55°C to 125°C. Applications requiring operation outside this range require alternative connector selection.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. No compliance advantage exists between the two options.

Q: What is the significance of the gold contact finish thickness specification?

A: The 30.0µin (0.76µm) gold plating on mating contacts ensures consistent contact resistance and corrosion resistance across both parts, maintaining electrical performance over the connector lifecycle.
