Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-108-04-L-DV-A is determined by strict alignment of the following critical parameters:

• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Operating Temperature Range: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze

The identified substitute TSM-108-01-L-DV-A maintains all critical electrical and mechanical parameters. The variance in Contact Length - Mating (0.230" vs 0.120") represents a design variation within the TSM series that accommodates different board-to-board or cable engagement depths while preserving all other functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both TSM-108-04-L-DV-A and TSM-108-01-L-DV-A are Active status components with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is determined by mating contact length requirements specific to the application's board-to-board or cable engagement depth. The TSM-108-04-L-DV-A provides 0.120" (3.05mm) mating contact length, while TSM-108-01-L-DV-A provides 0.230" (5.84mm) mating contact length. Both maintain full compliance with environmental and regulatory certifications across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: What determines if TSM-108-01-L-DV-A can substitute for TSM-108-04-L-DV-A?

A: The primary differentiator is Contact Length - Mating. Both parts share identical pitch (0.100"), position count (16), row configuration (2), contact type (Male Pin), mounting method (Surface Mount), and operating temperature range (-55°C ~ 125°C). Substitution is valid when the application's engagement depth accommodates the longer 0.230" mating contact of the TSM-108-01-L-DV-A.

Q: Are there electrical compatibility concerns between these parts?

A: No. Both parts use identical contact material (Phosphor Bronze), contact finish (Gold), insulation material (LCP), and termination method (Solder). Electrical performance characteristics are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TSM-108-04-L-DV-A and TSM-108-01-L-DV-A are ROHS3 compliant with MSL 1 (Unlimited) rating and UL94 V-0 flammability classification.

Q: What is the impact of different Contact Length - Mating values?

A: Contact Length - Mating affects the depth of engagement between mating connectors. The TSM-108-04-L-DV-A (0.120") is suitable for shallow engagement applications, while TSM-108-01-L-DV-A (0.230") accommodates deeper board-to-board spacing. Selection depends on PCB layout and mechanical clearance requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability requires verification that the PCB layout and mating connector depth accommodate the specific Contact Length - Mating of the selected part. Physical board-to-board spacing must align with the chosen connector's engagement depth.
