Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-105-04-F-DV-A is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C minimum
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 or equivalent

The substitute part 95278-101A10LF (Amphenol ICC / FCI) meets all critical substitution criteria. Both parts share identical mating pitch, position count, row configuration, contact type, surface mount design, solder termination, push-pull fastening, gold mating finish, and UL94 V-0 flammability rating. Both are RoHS compliant and operate within the required temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the TSM-105-04-F-DV-A and 95278-101A10LF are active products with full RoHS compliance and UL94 V-0 flammability certification. The primary differences are:

Contact Length - Mating: The TSM-105-04-F-DV-A features a shorter mating contact length of 0.120" (3.05mm), while the 95278-101A10LF provides 0.232" (5.90mm). This difference affects mating depth and may influence PCB layout and connector stack height considerations.

Contact Finish Thickness: The 95278-101A10LF provides a thicker gold plating at 30.0µin (0.76µm) compared to the TSM-105-04-F-DV-A at 3.00µin (0.076µm), offering enhanced durability in high-cycle mating applications.

Insulation Material: The TSM-105-04-F-DV-A uses Liquid Crystal Polymer (LCP), while the 95278-101A10LF uses Thermoplastic. Both materials meet UL94 V-0 requirements.

Operating Temperature Range: The 95278-101A10LF extends the lower temperature limit to -65°C, providing broader environmental coverage.

Selection should be based on specific application requirements regarding contact mating depth, plating durability, and environmental temperature extremes.

Frequently Asked Questions (FAQ)

Q: Can the 95278-101A10LF directly replace the TSM-105-04-F-DV-A in existing designs?

A: Direct replacement is possible from an electrical and mechanical interface perspective, as both connectors share identical mating pitch (0.100"), position count (10), row configuration (2 rows), contact type (male pin), and fastening mechanism (push-pull). However, the difference in contact mating length (0.120" vs. 0.232") must be evaluated against PCB layout and mating connector specifications to ensure proper engagement depth.

Q: What is the significance of the contact finish thickness difference?

A: The 95278-101A10LF provides 30.0µin (0.76µm) of gold plating compared to 3.00µin (0.076µm) on the TSM-105-04-F-DV-A. Thicker plating generally provides improved wear resistance and contact reliability in applications with frequent mating cycles or harsh environmental exposure.

Q: Are both parts suitable for the same temperature range applications?

A: The TSM-105-04-F-DV-A operates from -55°C to 125°C, while the 95278-101A10LF operates from -65°C to 125°C. The 95278-101A10LF is suitable for all TSM-105-04-F-DV-A applications and extends coverage to lower temperature environments.

Q: What packaging differences exist between these parts?

A: The TSM-105-04-F-DV-A is supplied in Tube packaging, while the 95278-101A10LF is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly automation requirements.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant, UL94 V-0 rated, MSL 1 (Unlimited), and classified as EAR99 with HTSUS code 8536.69.4040. The TSM-105-04-F-DV-A is ROHS3 compliant, while the 95278-101A10LF is RoHS compliant. Both meet the same regulatory requirements for this product category.
