Engineering Selection Recommendations

Both the HTSW-203-14-TM-S and TSW-203-14-T-S are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on insulation material requirements and environmental storage conditions.

The HTSW-203-14-TM-S employs Liquid Crystal Polymer (LCP) insulation with a Natural color finish and carries an MSL rating of Not Applicable, indicating superior moisture resistance and suitability for applications with minimal moisture sensitivity concerns.

The TSW-203-14-T-S uses Polybutylene Terephthalate (PBT) insulation with a Black color finish and carries an MSL rating of 1 (Unlimited), indicating standard moisture handling with no storage time restrictions.

Both parts maintain identical electrical and mechanical performance across the specified operating temperature range of -55°C to 105°C and are suitable for direct substitution in through-hole solder applications requiring 3-position, 0.200" pitch rectangular connectors.

Frequently Asked Questions (FAQ)

Q: Can TSW-203-14-T-S replace HTSW-203-14-TM-S in existing designs?

A: Yes. Both parts share identical connector type, contact configuration, pitch spacing, mounting methodology, and thermal operating range. The primary difference is insulation material composition and moisture sensitivity rating. Substitution is valid for applications where the insulation material change from LCP to PBT does not conflict with design requirements.

Q: What is the difference between LCP and PBT insulation materials?

A: Liquid Crystal Polymer (LCP) offers superior moisture resistance and is classified as Not Applicable for MSL. Polybutylene Terephthalate (PBT) is a standard engineering plastic with MSL 1 (Unlimited), meaning no moisture-related storage time restrictions apply. Material selection depends on application environmental exposure and storage conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-203-14-TM-S and TSW-203-14-T-S are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for restricted substance use and fire safety standards.

Q: Do these connectors have the same physical dimensions?

A: Yes. Both parts have identical contact lengths, insulation height, pitch spacing, and overall form factor. The only visual difference is insulation color: Natural for HTSW-203-14-TM-S and Black for TSW-203-14-T-S.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 105°C, providing equivalent thermal performance for industrial and commercial applications.

Q: Are inventory levels a factor in part selection?

A: HTSW-203-14-TM-S has 638 units in stock, while TSW-203-14-T-S has 674 units in stock. Both maintain adequate inventory for production requirements.
