Key Parameters

Substitute Part Grouping Explanation

The TSW-150-29-S-S qualifies as a direct substitute for the HTSW-150-29-S-S based on the following critical parameters:

• Pitch - Mating: Both parts maintain 0.100" (2.54mm) spacing, ensuring mechanical and electrical compatibility
• Number of Positions: Both feature 50 positions in a single-row configuration
• Contact Type: Both are male pin headers with identical contact geometry
• Mounting Type: Both are through-hole mounted with solder termination
• Operating Temperature Range: Both operate across -55°C ~ 125°C
• Material Flammability Rating: Both meet UL94 V-0 classification
• RoHS Compliance: Both are ROHS3 compliant
• Connector Style: Both are unshrouded, board-to-board or cable headers with push-pull fastening

The primary difference lies in the insulation material composition: HTSW uses Liquid Crystal Polymer (LCP) with natural color, while TSW uses Polybutylene Terephthalate (PBT) with black color. Both materials meet the same flammability and compliance standards.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-150-29-S-S and TSW-150-29-S-S are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Material Composition: The HTSW series uses Liquid Crystal Polymer (LCP) insulation, while the TSW series uses Polybutylene Terephthalate (PBT). Both materials satisfy UL94 V-0 flammability requirements and support the full operating temperature range of -55°C ~ 125°C.

Moisture Sensitivity: The HTSW-150-29-S-S carries no moisture sensitivity level designation (Not Applicable), while the TSW-150-29-S-S is rated MSL 1 (Unlimited). This distinction may be relevant for storage and handling protocols in moisture-sensitive environments.

Compliance and Certifications: Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, ensuring regulatory equivalence.

Availability: Both parts are in active production with adequate inventory levels (929 units for HTSW and 772 units for TSW).

Frequently Asked Questions (FAQ)

Q: Are the HTSW-150-29-S-S and TSW-150-29-S-S mechanically interchangeable?

A: Yes. Both parts share identical pitch (0.100"), position count (50), contact geometry, mounting type (through-hole), and overall dimensions. They are mechanically interchangeable in board-level applications.

Q: What is the difference in insulation material, and does it affect performance?

A: The HTSW uses Liquid Crystal Polymer (LCP) while the TSW uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability standards and support the identical operating temperature range (-55°C ~ 125°C). Material selection depends on specific application requirements and environmental conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both the HTSW-150-29-S-S and TSW-150-29-S-S are ROHS3 compliant and carry identical regulatory classifications.

Q: What is the significance of the moisture sensitivity level difference?

A: The HTSW-150-29-S-S has no moisture sensitivity level designation, while the TSW-150-29-S-S is rated MSL 1 (Unlimited). MSL 1 indicates the part has unlimited shelf life without moisture control measures. This may influence storage and handling procedures depending on facility conditions.

Q: Can I use these parts interchangeably in existing designs?

A: Yes, provided the design does not specify material-dependent requirements. Both parts maintain identical electrical and mechanical characteristics, contact finishes, and operating parameters. Verify that the insulation material change (LCP to PBT or vice versa) does not conflict with application-specific constraints.

Q: What are the contact specifications for both parts?

A: Both parts feature square-shaped male pins with phosphor bronze material, gold-plated mating surfaces (30.0µin thickness), and tin-plated posts. Contact length specifications are identical: 0.320" mating length and 0.910" post length.
