Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-203-07-G-D is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (6)
Number of rows (2)
Pitch - mating (0.200" / 5.08mm)
Row spacing - mating (0.100" / 2.54mm)
Mounting type (Through Hole)
Termination method (Solder)
Contact finish - mating (Gold)
Contact material (Phosphor Bronze)
Operating temperature range (-55°C ~ 125°C)
Material flammability rating (UL94 V-0)
RoHS compliance status (ROHS3 Compliant)

The TSW-203-07-G-D meets all these critical parameters and qualifies as a direct substitute. Variations in insulation material (Liquid Crystal Polymer vs. Polybutylene Terephthalate), insulation color, and moisture sensitivity level do not affect functional or mechanical compatibility for this connector category.

Engineering Selection Recommendations

Both the HTSW-203-07-G-D and TSW-203-07-G-D are active products manufactured by Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Both connectors meet identical electrical and mechanical specifications for mating pitch, contact configuration, termination method, and operating temperature range.

Selection between these parts should be based on application-specific requirements and availability. The HTSW series uses Liquid Crystal Polymer (LCP) insulation material with natural color, while the TSW series uses Polybutylene Terephthalate (PBT) insulation material with black color. Both materials are suitable for through-hole solder applications within the specified temperature range. The TSW-203-07-G-D carries a moisture sensitivity level rating of 1 (Unlimited), while the HTSW-203-07-G-D is not applicable for moisture sensitivity, indicating different handling requirements during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can TSW-203-07-G-D be used as a direct replacement for HTSW-203-07-G-D in existing designs?

A: Yes. Both connectors share identical mating pitch (0.200" / 5.08mm), row spacing (0.100" / 2.54mm), contact configuration (6 positions, 2 rows), contact material (Phosphor Bronze), contact finish (Gold), mounting type (Through Hole), and termination method (Solder). They are mechanically and electrically compatible.

Q: What is the difference in insulation material between these two parts?

A: The HTSW-203-07-G-D uses Liquid Crystal Polymer (LCP) insulation, while the TSW-203-07-G-D uses Polybutylene Terephthalate (PBT) insulation. Both materials meet UL94 V-0 flammability requirements and operate across the same temperature range (-55°C ~ 125°C). Material selection may depend on specific environmental or mechanical requirements of the application.

Q: Are there any moisture sensitivity considerations when substituting these parts?

A: The TSW-203-07-G-D has a moisture sensitivity level (MSL) rating of 1 (Unlimited), indicating no special moisture handling requirements. The HTSW-203-07-G-D is not applicable for MSL rating. Verify storage and assembly conditions based on your specific manufacturing process requirements.

Q: Do both parts have the same contact finish specifications?

A: Yes. Both connectors feature gold-plated contacts with identical finish thickness specifications: 10.0µin (0.25µm) on mating surfaces and 3.00µin (0.076µm) on post surfaces. Contact material is Phosphor Bronze for both parts.

Q: Are both parts RoHS compliant?

A: Yes. Both the HTSW-203-07-G-D and TSW-203-07-G-D are ROHS3 compliant and carry active product status from Samtec Inc.
