Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the SSW-111 series are qualified based on identical electrical and mechanical parameters. The following criteria determine substitution eligibility:

Critical Parameters (Must Match):

• Number of positions: 22
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination: Solder
• Contact type: Forked
• Current rating: 4.7A per contact
• Operating temperature: -55°C ~ 125°C
• Contact finish - mating: Gold
• Contact finish - post: Tin
• Insulation material: Liquid Crystal Polymer (LCP)
• Material flammability rating: UL94 V-0
• RoHS status: ROHS3 Compliant

The substitute parts SSW-111-01-F-D and SSW-111-01-FM-D meet all critical electrical and mechanical parameters, making them functionally equivalent for applications requiring the SSW-111-21-F-D.

Frequently Asked Questions (FAQ)

Q: Are SSW-111-01-F-D and SSW-111-01-FM-D direct replacements for SSW-111-21-F-D?

A: Yes. All three connectors share identical electrical and mechanical specifications including 22 positions, 0.100" pitch, 4.7A current rating, and -55°C to 125°C operating temperature range. They are functionally equivalent for applications requiring these parameters.

Q: What is the difference between these substitute parts?

A: The part numbers reflect internal Samtec configuration variants. All critical parameters—connector type, contact configuration, pitch, current rating, temperature range, and compliance certifications—are identical across all three parts.

Q: Do these connectors have different moisture sensitivity levels?

A: SSW-111-21-F-D and SSW-111-01-FM-D are listed as Not Applicable for MSL. SSW-111-01-F-D is rated MSL 1 (Unlimited). This difference does not affect substitution eligibility for standard applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three connectors meet ROHS3 compliance requirements and carry UL94 V-0 flammability certification.

Q: Which part should be selected based on availability?

A: Selection should prioritize inventory levels and lead time requirements. SSW-111-01-F-D has the highest stock level at 1111 units, followed by SSW-111-21-F-D at 921 units and SSW-111-01-FM-D at 883 units.
