SSW-125-01-G-S Equivalent & Substitute Parts

Part Overview

The SSW-125-01-G-S is a 25-position receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts and is rated for 4.7A per contact with an operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts may be required due to inventory constraints, packaging preferences, or specific application requirements where alternative mechanical or electrical characteristics are acceptable within defined parameters.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 2-534237-3 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

• Connector Type & Position Count: Both are 25-position receptacles
• Pitch & Mounting: Identical 0.100" (2.54mm) pitch with through-hole solder termination
• Fastening & Interface: Both use push-pull fastening for board-to-board or cable applications
• Mating Contact Finish: Both feature gold-plated mating contacts
• Compliance: Both are ROHS3 compliant and carry EAR99 ECCN classification

The substitute maintains functional and mechanical compatibility for standard rectangular connector applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with ROHS3 compliance and EAR99 classification. The SSW-125-01-G-S provides a higher current rating of 4.7A per contact compared to the 2-534237-3 at 2A per contact. The substitute part offers an extended lower operating temperature limit of -65°C versus -55°C. Selection between these parts should be based on application current requirements and thermal operating conditions. Both parts maintain compatible mechanical interfaces and gold-plated mating contacts suitable for standard rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can 2-534237-3 be used as a direct replacement for SSW-125-01-G-S?

A: Both connectors share identical pitch (0.100"), position count (25), mounting type (through-hole), and fastening mechanism (push-pull). However, the current rating differs: SSW-125-01-G-S is rated at 4.7A per contact while 2-534237-3 is rated at 2A per contact. Substitution is valid only if application current requirements do not exceed 2A per contact.

Q: What are the packaging differences?

A: SSW-125-01-G-S is supplied in bulk packaging, while 2-534237-3 is supplied in tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes, both SSW-125-01-G-S and 2-534237-3 are ROHS3 compliant.

Q: What is the temperature operating range difference?

A: SSW-125-01-G-S operates from -55°C to 125°C, while 2-534237-3 operates from -65°C to 125°C. The substitute part supports a lower minimum temperature.

Q: Do the connectors use the same contact finish?

A: Both use gold-plated mating contacts. The mating contact finish thickness differs: SSW-125-01-G-S has 20.0µin (0.51µm) while 2-534237-3 has 30.0µin (0.76µm).
