Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSW-109-15-L-S is determined by strict alignment of the following critical parameters:

• Connector Type: Header (male pin contact type)
• Number of Positions and Rows: 9 positions, single row configuration
• Pitch - Mating: 0.100" (2.54mm) spacing
• Mounting Type: Through hole solder termination
• Contact Geometry: Square contact shape with gold mating finish
• Contact Material: Phosphor bronze base material
• Operating Temperature Range: -55°C ~ 125°C
• Compliance: ROHS3 Compliant, UL94 V-0 flammability rating

The HTSW-109-15-L-S qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. Variations in insulation material (PBT versus LCP) and insulation color do not affect functional compatibility in standard board-to-board or cable connection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TSW-109-15-L-S and HTSW-109-15-L-S maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• Supply Availability: Current inventory levels (TSW-109-15-L-S: 1120 pcs; HTSW-109-15-L-S: 1051 pcs) may influence procurement decisions.
• Insulation Material Compatibility: PBT (TSW series) and LCP (HTSW series) offer equivalent electrical performance. LCP provides superior dimensional stability and lower moisture absorption in high-humidity environments.
• Design Continuity: If the original design specifies TSW-109-15-L-S, the HTSW-109-15-L-S serves as a direct functional equivalent for applications where insulation material substitution is acceptable.

Frequently Asked Questions (FAQ)

Q: Can HTSW-109-15-L-S replace TSW-109-15-L-S in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications including connector type, position count, pitch, contact geometry, and operating temperature range. The insulation material difference (PBT versus LCP) does not affect functional compatibility in standard applications.

Q: What is the significance of the insulation material difference?

A: PBT and LCP are both thermoplastic materials meeting UL94 V-0 flammability requirements. LCP exhibits lower moisture absorption and superior dimensional stability at elevated temperatures. For most applications, this difference is not functionally significant.

Q: Are the contact dimensions identical between these parts?

A: Yes. Mating contact length (0.520"), post length (0.110"), overall contact length (0.730"), and insulation height (0.100") are identical across both parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TSW-109-15-L-S and HTSW-109-15-L-S are ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What determines compatibility with mating connectors?

A: Compatibility is determined by pitch (0.100"), number of positions (9), contact type (male pin), and contact geometry (square). Both parts meet these criteria identically.
