Key Parameters

Substitute Part Grouping Explanation

The TST-110-05-L-D-RA qualifies as a substitute for the TSS-110-05-L-D-RA based on alignment of critical electrical and mechanical parameters. Both parts share identical specifications for connector type (Header), contact type (Male Pin), position count (20), row configuration (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), mounting method (Through Hole, Right Angle), shrouding (Shrouded - 4 Wall), termination (Solder), contact finish (Gold mating surface), contact material (Phosphor Bronze), operating temperature range (-55°C ~ 125°C), flammability rating (UL94 V-0), and compliance status (ROHS3 Compliant, MSL 1).

The primary distinction lies in the Style parameter: TSS-110-05-L-D-RA is configured for Board to Board or Cable applications, while TST-110-05-L-D-RA is specified for Board to Cable/Wire applications. Additionally, TST-110-05-L-D-RA includes Glass Filled polybutylene terephthalate insulation and specifies a current rating of 3.4A per contact, whereas the main part does not provide these specifications in the available data.

Parameter Comparison

Engineering Selection Recommendations

Both TSS-110-05-L-D-RA and TST-110-05-L-D-RA maintain Active product status with equivalent compliance certifications (ROHS3 Compliant, UL94 V-0, MSL 1). Selection between these parts depends on application-specific requirements regarding connector style and insulation material composition.

For applications requiring Board to Board or Cable connectivity with standard PBT insulation, the TSS-110-05-L-D-RA remains the primary specification. The TST-110-05-L-D-RA serves as a functional substitute when Board to Cable/Wire configuration is acceptable and when glass-filled PBT insulation properties align with thermal or mechanical requirements. The TST-110-05-L-D-RA additionally specifies a 3.4A per contact current rating, providing defined electrical performance for power distribution applications.

Both parts share identical electrical and mechanical interfaces, pitch specifications, and environmental operating ranges, supporting direct substitution within design constraints specific to connector style and insulation material requirements.

Frequently Asked Questions (FAQ)

Q: Can TST-110-05-L-D-RA replace TSS-110-05-L-D-RA in existing designs?

A: TST-110-05-L-D-RA qualifies as a substitute when the application accommodates Board to Cable/Wire configuration instead of Board to Board or Cable. Both parts maintain identical pitch (0.100"/2.54mm), position count (20), row spacing (0.100"/2.54mm), mounting method (Through Hole, Right Angle), and operating temperature range (-55°C ~ 125°C). Verify connector style compatibility with your application before substitution.

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

A: TSS-110-05-L-D-RA uses standard Polybutylene Terephthalate (PBT) insulation. TST-110-05-L-D-RA uses glass-filled PBT insulation, which provides enhanced mechanical strength and thermal stability. Glass-filled variants are suitable for applications requiring improved dimensional stability or higher mechanical stress resistance.

Q: Are both parts RoHS compliant?

A: Yes, both TSS-110-05-L-D-RA and TST-110-05-L-D-RA are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), supporting deployment in regulated environments without moisture sensitivity constraints.

Q: What is the current rating for these connectors?

A: TST-110-05-L-D-RA specifies 3.4A per contact. TSS-110-05-L-D-RA does not provide a current rating specification in available documentation. For applications requiring defined current capacity, TST-110-05-L-D-RA provides explicit electrical performance parameters.

Q: Do both parts feature keying?

A: Yes, both TSS-110-05-L-D-RA and TST-110-05-L-D-RA include keying slots as a standard feature, preventing incorrect mating orientation.

Q: What is the contact finish specification?

A: Both parts feature gold-plated mating contacts (10.0µin/0.25µm thickness) with tin-plated posts, providing corrosion resistance and reliable electrical contact across the operating temperature range.
