Part Overview

The SSW-120-01-S-D is a 40-position rectangular receptacle connector manufactured by Samtec Inc., designed for board-to-board or cable applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently active in production with 1114 units in stock. Alternative equivalent parts may be required due to supply constraints, packaging preferences, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSW-120-01-S-D is determined by strict alignment of the following critical parameters:

Primary Matching Criteria (Non-Negotiable):

• Connector type: Receptacle
• Number of positions: 40
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Contact finish thickness - mating: 30.0µin (0.76µm)
• Insulation color: Black
• Style: Board to board or cable

Secondary Compatibility Parameters:

• Operating temperature range (minimum acceptable: -55°C to 125°C or better)
• Material flammability rating (UL94 V-0 preferred)
• RoHS compliance status
• Current rating per contact (minimum acceptable: 4.7A or equivalent)

All three substitute parts meet the primary matching criteria. Variations in secondary parameters are noted in the comparison table below.

Parameter Comparison

Engineering Selection Recommendations

2-534206-0 (TE Connectivity AMP Connectors): This part meets all primary matching criteria and offers the highest inventory availability at 126400 units. The extended operating temperature range (-65°C to 125°C) provides superior low-temperature performance. However, the current rating is reduced to 2A per contact compared to the original 4.7A specification, and the RoHS status is not applicable. The contact finish post uses tin-lead rather than tin. Packaging is supplied in tube format rather than bulk. This substitute is suitable for applications where current requirements do not exceed 2A per contact and extended low-temperature operation is beneficial.

7-534206-0 (TE Connectivity AMP Connectors): This part matches all primary criteria and maintains UL94 V-0 flammability rating and RoHS compliance status. The extended operating temperature range (-65°C to 125°C) exceeds the original specification. Current rating is 2A per contact. Inventory availability is 2130 units. Packaging is supplied in tube format. This substitute is suitable for applications where current requirements do not exceed 2A per contact and RoHS compliance is required.

929852-01-20-RB (3M): This part meets all primary matching criteria and maintains UL94 V-0 flammability rating and RoHS compliance. The operating temperature range is -40°C to 105°C, which is narrower than the original specification. Current rating is 2A per contact. A voltage rating of 1500V is specified. Inventory availability is 1256 units. Packaging is supplied in bulk format. This substitute is suitable for applications where current requirements do not exceed 2A per contact and high voltage isolation is required.

All three substitutes are active products with established supply chains. Selection should be based on specific application requirements regarding current capacity, operating temperature range, voltage isolation, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts interchangeably with the SSW-120-01-S-D?

A: The substitute parts are mechanically and electrically compatible for mating and mounting purposes, as they share identical pitch spacing, row configuration, connector type, and fastening mechanism. However, the reduced current rating (2A versus 4.7A per contact) in all substitutes must be evaluated against your application's power requirements. Verify that your circuit design does not exceed 2A per contact when using any of these alternatives.

Q: What are the key differences between the substitute parts?

A: The primary differences are: (1) Operating temperature range—2-534206-0 and 7-534206-0 support -65°C to 125°C, while 929852-01-20-RB supports -40°C to 105°C; (2) Compliance certifications—7-534206-0 and 929852-01-20-RB are RoHS compliant, while 2-534206-0 has not applicable status; (3) Voltage rating—929852-01-20-RB specifies 1500V, while others do not specify; (4) Packaging format—2-534206-0 and 7-534206-0 are supplied in tubes, while SSW-120-01-S-D and 929852-01-20-RB are supplied in bulk.

Q: Why is the current rating lower in the substitute parts?

A: The current rating is a specified electrical characteristic determined by the contact material, contact geometry, and thermal design of each connector series. The SSW series is rated for 4.7A per contact, while the AMPMODU Mod II and 3M 929 series are rated for 2A per contact. This is a fundamental design difference between the connector families and cannot be changed through substitution.

Q: Are there any mechanical compatibility concerns with different insulation heights and contact post lengths?

A: The insulation heights and contact post lengths vary slightly among the parts (ranging from 0.320" to 0.335" for insulation height and 0.104" to 0.125" for contact post length). These variations are within acceptable tolerances for standard 0.100" pitch connector applications and do not prevent mechanical mating. However, if your PCB layout or connector housing has tight dimensional constraints, verify that the specific substitute part's dimensions are compatible with your design.

Q: Which substitute should I choose for high-reliability applications?

A: For high-reliability applications, 7-534206-0 is recommended due to its UL94 V-0 flammability rating, RoHS compliance, extended operating temperature range (-65°C to 125°C), and established TE Connectivity supply chain. Ensure that the 2A per contact current rating meets your application requirements.

Q: Can I mix different substitute parts in the same assembly?

A: While all parts are mechanically compatible for mating, mixing different manufacturers or series in the same assembly is not recommended for production designs. Maintain consistency with a single part number to ensure uniform electrical performance, thermal characteristics, and long-term reliability.
