Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-104-09-G-S-RE is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: Header, through-hole, right-angle mounting
• Position Count & Pitch: 4 positions at 0.100" (2.54mm) mating pitch
• Contact Type: Male pin with solder termination
• Electrical & Mechanical Compatibility: Matching contact length (mating), insulation height, and contact shape
• Environmental Ratings: Operating temperature range and flammability compliance
• Compliance Status: RoHS compliance and product active status

The identified substitute part 5-103325-4 (TE Connectivity AMP Connectors) meets these core substitution criteria across all critical dimensions and electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-104-09-G-S-RE and 5-103325-4 are active products with current manufacturing status and full RoHS compliance. Selection between these parts is based on application-specific operating temperature requirements and contact post specifications.

The TSW-104-09-G-S-RE operates across -55°C to 125°C with phosphor bronze contacts and gold-plated posts (3.00µin thickness). The 5-103325-4 operates across -65°C to 105°C with copper alloy contacts and tin-plated posts (100.0µin thickness). Applications requiring the extended upper temperature limit of 125°C necessitate the Samtec part. Applications operating below -55°C or requiring extended lower temperature performance to -65°C may utilize the TE Connectivity substitute.

Both parts carry UL94 V-0 flammability certification and unlimited moisture sensitivity level (MSL 1), suitable for standard industrial and commercial environments.

Frequently Asked Questions (FAQ)

Q: Can 5-103325-4 be used as a direct replacement for TSW-104-09-G-S-RE in all applications?

A: The 5-103325-4 is mechanically and electrically compatible for applications operating within the overlapping temperature range of -55°C to 105°C. Applications requiring operation above 105°C must use the TSW-104-09-G-S-RE to maintain the specified -55°C to 125°C operating range.

Q: What are the key differences between these two connectors?

A: The primary differences are operating temperature range (TSW-104: -55°C to 125°C; 5-103325-4: -65°C to 105°C), contact material (phosphor bronze vs. copper alloy), and post finish thickness (3.00µin gold vs. 100.0µin tin). Mating contact specifications, pitch, position count, and mounting configuration are identical.

Q: Are both parts currently available for procurement?

A: Yes. The TSW-104-09-G-S-RE has 676 units in stock, and the 5-103325-4 has 753 units in stock, both as new original inventory.

Q: Do both connectors meet RoHS compliance requirements?

A: Yes. The TSW-104-09-G-S-RE is ROHS3 compliant, and the 5-103325-4 is RoHS compliant. Both meet current environmental and hazardous substance restrictions.

Q: What is the significance of the contact post finish difference?

A: The TSW-104-09-G-S-RE uses 3.00µin gold plating on posts, while the 5-103325-4 uses 100.0µin tin plating. This affects solderability characteristics and long-term corrosion resistance in different environmental conditions. Gold provides superior corrosion resistance; tin offers standard soldering performance.
