SSW-105-21-L-D Equivalent & Substitute Parts

Part Overview

The SSW-105-21-L-D is a 10 position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This connector features through-hole solder termination, gold-plated mating contacts, and forked contact geometry. The product is currently active in production with 897 pieces available in stock.

Alternative models become necessary when inventory constraints exist, when specific packaging requirements differ, or when operational parameters align with substitute offerings while maintaining full electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The SSW-105-01-L-D qualifies as a direct substitute for the SSW-105-21-L-D based on the following critical parameters:

• Identical connector type (Receptacle)
• Identical number of positions (10)
• Identical pitch spacing (0.100" / 2.54mm)
• Identical row configuration (2 rows at 0.100" spacing)
• Identical mounting method (Through Hole)
• Identical termination type (Solder)
• Identical contact finish specification (Gold mating surface)
• Identical current rating (4.7A per Contact)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical flammability rating (UL94 V-0)
• Identical RoHS compliance status (ROHS3 Compliant)

Both parts share the same base product number (SSW-105) and series designation (SSW), confirming mechanical and electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the SSW-105-21-L-D and SSW-105-01-L-D are active production components from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and moisture sensitivity requirements.

The SSW-105-01-L-D offers significantly higher stock availability (2800 pieces versus 897 pieces) and carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The SSW-105-21-L-D carries an MSL designation of Not Applicable, which does not restrict its use in standard manufacturing environments.

Both parts maintain ROHS3 compliance and identical performance characteristics across all critical parameters including current rating, operating temperature range, and contact geometry. Either part is suitable for direct substitution in applications requiring 10-position rectangular connectors with 0.100" pitch spacing and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Are SSW-105-21-L-D and SSW-105-01-L-D mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch spacing (0.100"), number of positions (10), row configuration (2 rows), insulation height (0.335"), and contact geometry (square, forked contacts). They are direct mechanical substitutes.

Q: Are these connectors electrically equivalent?

A: Yes. Both parts carry identical electrical ratings: 4.7A per contact, operating temperature range of -55°C to 125°C, and identical contact materials (Phosphor Bronze with gold mating finish and tin post finish). They are direct electrical substitutes.

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

A: The primary differences are inventory availability and moisture sensitivity level designation. The SSW-105-01-L-D has higher stock (2800 pieces) and carries an MSL rating of 1 (Unlimited), while the SSW-105-21-L-D has lower stock (897 pieces) and an MSL designation of Not Applicable. All electrical and mechanical parameters are identical.

Q: Can I use SSW-105-01-L-D as a replacement for SSW-105-21-L-D in my design?

A: Yes. The SSW-105-01-L-D is a direct substitute with no design modifications required. PCB footprints, mating connector compatibility, and performance characteristics remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both the SSW-105-21-L-D and SSW-105-01-L-D are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What does MSL rating mean for these connectors?

A: Moisture Sensitivity Level (MSL) indicates moisture absorption characteristics during storage. The SSW-105-01-L-D with MSL 1 (Unlimited) has no moisture sensitivity restrictions. The SSW-105-21-L-D with MSL Not Applicable indicates standard handling conditions apply. Both are suitable for typical manufacturing environments.
