Key Parameters

Substitute Part Grouping Explanation

The SSW-121-01-G-P has one identified substitute part: SSW-121-01-G-S. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Connector Type: Receptacle
• Number of Positions: 21
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Contact Finish - Mating: Gold
• Current Rating: 4.7A per Contact
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Series: SSW
• Base Product Number: SSW-121

The substitute part SSW-121-01-G-S maintains all critical electrical and mechanical specifications, differing only in the fastening mechanism designation suffix. Both parts are manufactured by Samtec Inc. and are active products with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both SSW-121-01-G-P and SSW-121-01-G-S are active products manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Product availability and inventory status
• Fastening mechanism requirements specific to the application
• Supply chain lead times and procurement timelines
• ROHS3 compliance certification, which both parts satisfy
• EAR99 export classification applicability

Both connectors meet UL94 V-0 flammability requirements and operate across the full -55°C to 125°C temperature range with 4.7A per-contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can SSW-121-01-G-S be used as a direct replacement for SSW-121-01-G-P?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, pitch, mounting method, contact finish, current rating, and operating temperature range. The difference in part number suffix reflects a variation in fastening mechanism designation only.

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

A: Substitution is valid when the following parameters remain constant: 21-position receptacle configuration, 0.100" (2.54mm) pitch, through-hole mounting, gold contact finish, 4.7A per-contact current rating, -55°C to 125°C operating temperature, and UL94 V-0 flammability rating.

Q: Are both parts RoHS compliant?

A: Yes. Both SSW-121-01-G-P and SSW-121-01-G-S are ROHS3 compliant.

Q: What is the difference between the -P and -S suffix designations?

A: The suffix designations indicate variations in fastening mechanism type. Both parts maintain identical electrical and mechanical performance specifications for the 21-position receptacle connector configuration.

Q: What is the current rating per contact?

A: Both parts are rated for 4.7A per contact.

Q: What is the operating temperature range?

A: Both connectors operate across -55°C to 125°C.
