TSW-150-22-G-S-RA Equivalent & Substitute Parts

Part Overview

The TSW-150-22-G-S-RA is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board or cable applications. This 50-position connector operates at 0.100" (2.54mm) pitch and features gold-plated phosphor bronze contacts with solder termination. The part is ROHS3 compliant and rated for operating temperatures from -55°C to 125°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific design requirements necessitate alternative connector configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-150-22-G-S-RA is determined by the following critical parameters:

• Connector Type & Contact Type: Header with male pins
• Number of Positions & Pitch: 50 positions at 0.100" (2.54mm) mating pitch
• Mounting Configuration: Through-hole, right-angle orientation
• Termination Method: Solder termination
• Contact Material & Finish: Phosphor bronze with gold plating on mating surfaces
• Operating Temperature Range: -55°C to 125°C
• Compliance: ROHS3 compliant, UL94 V-0 flammability rating

The identified substitute parts maintain these core electrical and mechanical parameters. Variations in insulation material (PBT versus LCP) and insulation height within specified tolerances do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TSW-150-22-G-S-RA, HTSW-150-22-G-S-RA, and TSW-150-22-G-S-RE—are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on the following criteria:

TSW-150-22-G-S-RA (Primary Part): Use when PBT insulation material is specified or preferred. Insulation height of 0.119" (3.02mm) with MSL rating of 1 (Unlimited) provides standard moisture handling for general applications.

HTSW-150-22-G-S-RA (Substitute): Use when LCP insulation material is required for enhanced thermal or chemical resistance. Insulation height of 0.122" (3.10mm) represents a minor dimensional variation. MSL rating of Not Applicable indicates different moisture sensitivity classification. This part is suitable for applications requiring LCP's superior performance characteristics.

TSW-150-22-G-S-RE (Substitute): Use as a direct functional equivalent to the primary part. Maintains identical PBT insulation material, insulation height, and MSL rating. This part provides alternative sourcing within the same TSW series.

All three parts maintain identical electrical contact specifications, operating temperature range, and mechanical mounting requirements, ensuring functional interchangeability in standard board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: Can TSW-150-22-G-S-RA be directly replaced with HTSW-150-22-G-S-RA?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical contact specifications, pitch, position count, and operating temperature range. The primary difference is insulation material (PBT versus LCP) and a minor insulation height variation of 0.003" (0.08mm). Verify that your application does not have specific insulation material requirements before substitution.

Q: What is the difference between TSW-150-22-G-S-RA and TSW-150-22-G-S-RE?

A: Both parts are from the Samtec TSW series with identical specifications for insulation material (PBT), insulation height, contact configuration, and moisture sensitivity level. The suffix difference (-RA versus -RE) indicates a variation in the connector design or configuration. Both are functionally equivalent for standard applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. TSW-150-22-G-S-RA, HTSW-150-22-G-S-RA, and TSW-150-22-G-S-RE are all ROHS3 compliant and carry UL94 V-0 flammability certification, meeting current environmental and safety standards.

Q: What does the insulation height difference between parts mean?

A: The insulation height variation between TSW-150-22-G-S-RA (0.119") and HTSW-150-22-G-S-RA (0.122") is 0.003" (0.08mm). This minor difference is within standard manufacturing tolerances and does not affect mating or mounting in typical applications. Verify board layout clearances if space constraints are critical.

Q: Which part should I select for high-temperature applications?

A: All three parts operate across the identical temperature range of -55°C to 125°C. Selection should be based on insulation material requirements and availability rather than thermal performance, as thermal specifications are equivalent.

Q: What is the significance of the MSL rating difference?

A: TSW-150-22-G-S-RA and TSW-150-22-G-S-RE carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. HTSW-150-22-G-S-RA lists MSL as Not Applicable, reflecting its LCP insulation material's inherent moisture resistance. Both classifications are suitable for standard manufacturing environments.
