SSW-125-22-S-D-LL Equivalent & Substitute Parts

Part Overview

The SSW-125-22-S-D-LL is a 50-position rectangular receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications. This connector features 0.100" (2.54mm) pitch through-hole mounting with gold-plated mating contacts and tin-plated posts. The product is active and widely used in applications requiring reliable interconnection with high current capacity per contact.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits component standardization across product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSW-125-22-S-D-LL is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Both parts must be receptacle connectors with exactly 50 positions
• Pitch & Row Configuration: Mating pitch of 0.100" (2.54mm) with 2 rows at 0.100" (2.54mm) spacing
• Mounting & Termination: Through-hole mounting with kinked pin solder termination
• Contact Specifications: Forked contact type with gold mating finish (30.0µin) and tin post finish
• Electrical Performance: 4.7A per contact current rating
• Environmental Compliance: Operating temperature range -55°C ~ 125°C, UL94 V-0 flammability rating, ROHS3 compliance
• Material & Construction: Liquid Crystal Polymer insulation with phosphor bronze contacts

The SSW-125-02-S-D-LL meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-125-22-S-D-LL and SSW-125-02-S-D-LL are active products from Samtec Inc. with identical electrical, mechanical, and environmental specifications. Selection between these parts may be based on inventory availability, lead time, or procurement preferences, as they are functionally equivalent.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The identical current rating of 4.7A per contact and operating temperature range of -55°C ~ 125°C ensure equivalent performance in thermal and electrical stress conditions.

Frequently Asked Questions (FAQ)

Q: Are SSW-125-22-S-D-LL and SSW-125-02-S-D-LL fully interchangeable?

A: Yes. Both connectors share identical specifications across all critical parameters: 50-position receptacle configuration, 0.100" pitch, through-hole mounting, gold mating contacts, and 4.7A per contact current rating. They are direct substitutes.

Q: What determines if a connector can substitute for the SSW-125-22-S-D-LL?

A: A substitute must match all of the following: 50-position receptacle type, 0.100" (2.54mm) mating pitch with 2-row configuration at 0.100" row spacing, through-hole termination, forked contact type, gold mating finish, tin post finish, 4.7A current rating, -55°C ~ 125°C operating temperature, UL94 V-0 flammability rating, and ROHS3 compliance.

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

A: Both connectors are rated for -55°C ~ 125°C operating temperature. Applications requiring operation beyond this range require alternative components.

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

A: Both parts are supplied in bulk packaging. Inventory levels may vary; SSW-125-22-S-D-LL has 981 pcs in stock while SSW-125-02-S-D-LL has 1030 pcs in stock at the time of reference.

Q: Do these connectors meet RoHS requirements?

A: Yes. Both SSW-125-22-S-D-LL and SSW-125-02-S-D-LL are ROHS3 compliant.
