Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TFML-110-02-SM-D are qualified based on identical electrical and mechanical parameters that ensure functional interchangeability:

Critical Parameters for Substitution:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 20
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Shrouding: Shrouded - 4 Wall
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts (TFML-110-02-S-D, TFML-110-02-S-D-A, and TFML-110-02-S-D-LC) maintain these core parameters. Variations exist only in optional features (Board Guide or Board Lock) that do not affect fundamental electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical compatibility with the TFML-110-02-SM-D. Selection between these parts is determined by application-specific requirements:

TFML-110-02-S-D: Standard configuration without additional features. Suitable for applications requiring basic header functionality with no mechanical guidance or locking requirements.

TFML-110-02-S-D-A: Includes Board Guide feature. Recommended for applications where connector alignment during mating is critical or where mechanical guidance improves assembly reliability.

TFML-110-02-S-D-LC: Includes Board Lock feature. Recommended for applications requiring positive mechanical retention or where vibration resistance is a design consideration.

All parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity classification. Product status is Active for all variants, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Are TFML-110-02-S-D, TFML-110-02-S-D-A, and TFML-110-02-S-D-LC electrically identical to TFML-110-02-SM-D?

A: Yes. All substitute parts maintain identical electrical parameters including contact material (Phosphor Bronze), contact finish (Gold mating / Tin post), pitch (0.050" / 1.27mm), and operating temperature range (-55°C ~ 125°C).

Q: What is the difference between the Board Guide and Board Lock features?

A: Board Guide (TFML-110-02-S-D-A) provides mechanical alignment assistance during connector mating. Board Lock (TFML-110-02-S-D-LC) provides positive mechanical retention after mating. The standard configuration (TFML-110-02-S-D) includes neither feature.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your PCB footprint accommodates the specific feature set. The Board Guide and Board Lock variants have different mechanical profiles that may require corresponding PCB cutouts or mounting provisions.

Q: Are all variants RoHS compliant?

A: Yes. All four parts are ROHS3 compliant with UL94 V-0 material flammability rating.

Q: What is the moisture sensitivity level for these connectors?

A: All parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part has the highest inventory availability?

A: TFML-110-02-S-D-A has the highest inventory at 1572 units, followed by TFML-110-02-S-D-LC at 1560 units and TFML-110-02-S-D at 1318 units.
