TSW-101-25-G-D-RA Equivalent & Substitute Parts

Part Overview

The TSW-101-25-G-D-RA is a rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 2-position connector features male pins with gold-plated contacts and is classified as Active product status. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative manufacturers.

Substitute Part Grouping Explanation

The 929745-01-01-I manufactured by 3M qualifies as a substitute for the TSW-101-25-G-D-RA based on the following alignment of critical parameters:

Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 2
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Insulation Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

These parameters define the mechanical and electrical compatibility envelope for rectangular connector headers in this category. The substitute part maintains dimensional and functional equivalence within the specified tolerance ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-101-25-G-D-RA and 929745-01-01-I maintain Active product status and comply with RoHS regulations. The TSW-101-25-G-D-RA supports an extended operating temperature range of -55°C to 125°C, while the 929745-01-01-I operates within -40°C to 105°C. Selection between these parts depends on application temperature requirements. Both connectors carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating suitability for standard storage and handling conditions. The contact material differs (Phosphor Bronze versus Copper Alloy), and the 3M substitute includes glass-filled polyester in its insulation composition. These material variations remain within acceptable substitution parameters for rectangular connector headers in this category.

Frequently Asked Questions (FAQ)

Q: What defines compatibility between the TSW-101-25-G-D-RA and 929745-01-01-I?

A: Compatibility is established through matching connector type, contact configuration, pitch spacing (0.100" / 2.54mm), mounting method (through-hole right-angle), termination type (solder), and contact finish (gold plating). Both parts maintain identical row spacing and position count, enabling direct mechanical and electrical interchangeability in board layouts designed for standard 2.54mm pitch headers.

Q: Are there temperature limitations when substituting the 3M part for the Samtec part?

A: The TSW-101-25-G-D-RA operates from -55°C to 125°C, while the 929745-01-01-I operates from -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the Samtec part. For applications within the -40°C to 105°C range, both parts are functionally equivalent.

Q: Do both parts meet the same regulatory compliance standards?

A: Both parts are RoHS compliant and carry UL94 V-0 flammability certification. The TSW-101-25-G-D-RA is ROHS3 compliant, while the 929745-01-01-I is RoHS compliant. Both maintain MSL 1 moisture sensitivity rating and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What are the dimensional differences between these connectors?

A: Contact length at mating differs by 0.002" (0.05mm), contact post length differs by 0.010" (0.25mm), and insulation height differs by 0.004" (0.11mm). These variations fall within standard manufacturing tolerances for rectangular connector headers and do not affect functional compatibility in standard applications.

Q: Can the 929745-01-01-I be used in applications originally designed for the TSW-101-25-G-D-RA?

A: Yes, provided the application operating temperature range does not exceed the 929745-01-01-I limits (-40°C to 105°C). The matching pitch spacing, contact configuration, mounting type, and termination method ensure mechanical and electrical compatibility within this temperature envelope.
