Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTSW-101-25-S-T-RA is determined by strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Contact type: Male Pin
• Number of positions: 3
• Number of rows: 3
• Row spacing: 0.100" (2.54mm)
• Contact material: Phosphor Bronze
• Contact finish - mating: Gold at 30.0µin (0.76µm)
• Contact finish - post: Tin
• Operating temperature range: -55°C ~ 125°C

Mechanical Compatibility Parameters:

• Connector type: Header
• Mounting type: Through Hole, Right Angle
• Termination: Solder
• Fastening type: Push-Pull
• Contact length - mating: 0.320" (8.13mm)
• Contact length - post: 0.100" (2.54mm)
• Insulation height: 0.320" (8.13mm)
• Contact shape: Square
• Material flammability rating: UL94 V-0

Regulatory Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• ECCN: EAR99
• HTSUS: 8536.69.4040

The TSW-101-25-S-T-RA meets all critical electrical and mechanical parameters. Variation in insulation material (PBT versus LCP) and insulation color does not affect functional interchangeability when all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the HTSW-101-25-S-T-RA and TSW-101-25-S-T-RA are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and EAR99 export classification. Selection between these parts is based on the following criteria:

Primary Part Selection (HTSW-101-25-S-T-RA):

• Higher inventory availability (1161 units)
• Liquid Crystal Polymer insulation material
• Natural insulation color

Substitute Part Selection (TSW-101-25-S-T-RA):

• Adequate inventory availability (804 units)
• Polybutylene Terephthalate insulation material
• Black insulation color
• Moisture sensitivity level: 1 (Unlimited)

Both parts satisfy identical electrical and mechanical requirements. The choice between them depends on application-specific requirements regarding insulation material properties and visual identification needs. Both maintain the same operating temperature range, contact specifications, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can TSW-101-25-S-T-RA be used as a direct replacement for HTSW-101-25-S-T-RA?

A: Yes. Both parts share identical electrical and mechanical specifications including contact type, pitch, row spacing, contact materials, finishes, operating temperature range, and flammability rating. The difference in insulation material (PBT versus LCP) and color does not affect functional interchangeability in applications where these parameters are not specifically constrained.

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

A: Liquid Crystal Polymer (LCP) and Polybutylene Terephthalate (PBT) are both thermoplastic materials used for connector insulation. The selection between them depends on application-specific thermal, mechanical, and chemical resistance requirements. Both materials in these parts meet UL94 V-0 flammability requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both HTSW-101-25-S-T-RA and TSW-101-25-S-T-RA are ROHS3 compliant, meeting all current lead-free and restricted substance requirements.

Q: What does the moisture sensitivity level (MSL) designation mean?

A: The TSW-101-25-S-T-RA carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The HTSW-101-25-S-T-RA is listed as Not Applicable for MSL, indicating no moisture-related constraints for this part type.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for operating temperatures from -55°C to 125°C. Applications requiring operation outside this range require alternative component selection.

Q: What is the contact pitch specification?

A: The row spacing (mating pitch) for both parts is 0.100" (2.54mm), the standard spacing for this connector family. This specification determines mechanical compatibility with mating connectors and PCB layout requirements.
