Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-105-22-S-D-A is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 10
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening Type: Push-Pull
• Termination: Solder
• Insulation Material: Liquid Crystal Polymer (LCP)

Secondary Compatibility Parameters:

• Current Rating: 2.9A per Contact (minimum acceptable)
• Voltage Rating: 275VAC (minimum acceptable)
• Operating Temperature Range: -55°C ~ 125°C (minimum acceptable)
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0

The identified substitutes maintain compatibility across all primary matching criteria. Variations in insulation height, contact length specifications, and certain secondary parameters do not affect functional interchangeability in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

TFM-105-12-S-D-A (Samtec Inc., Tiger Eye™ TFM Series)

This substitute maintains full electrical and mechanical compatibility with the TFM-105-22-S-D-A. Both parts share identical pitch, row spacing, contact ratings, voltage specifications, and operating temperature range. The primary difference is insulation height (0.290" vs. 0.360"), which does not affect functional interchangeability in standard applications. Both parts are Active status, ROHS3 compliant, and carry MSL 1 rating. Inventory availability is higher for this substitute (2506 pcs vs. 943 pcs).

TFM-105-32-S-D-A (Samtec Inc., Tiger Eye™ TFM Series)

This substitute is electrically and mechanically equivalent to the TFM-105-22-S-D-A across all critical parameters. Both maintain 2.9A per contact current rating, 275VAC voltage rating, and -55°C ~ 125°C operating temperature range. The difference is insulation height (0.435" vs. 0.360"), which accommodates applications requiring increased board clearance. Both parts are Active status and ROHS3 compliant with MSL 1 rating.

5-104693-1 (TE Connectivity AMP Connectors, AMPMODU 50/50 Grid Series)

This substitute shares the same pitch, row spacing, connector type, and shrouding configuration. However, it differs in current rating (0.5A per contact vs. 2.9A), contact shape (circular vs. square), contact length (0.120" vs. 0.139"), and operating temperature range (-65°C ~ 105°C vs. -55°C ~ 125°C). This part is suitable only for low-current applications and should be selected only when current requirements do not exceed 0.5A per contact. All parts are Active status and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can TFM-105-12-S-D-A be used as a direct replacement for TFM-105-22-S-D-A?

A: Yes. Both parts maintain identical pitch (0.050" / 1.27mm), row spacing, contact configuration, current rating (2.9A per contact), voltage rating (275VAC), and operating temperature range (-55°C ~ 125°C). The insulation height difference (0.290" vs. 0.360") does not affect electrical or mechanical interchangeability in standard board-to-board applications.

Q: What is the primary difference between TFM-105-22-S-D-A and TFM-105-32-S-D-A?

A: The primary difference is insulation height: TFM-105-22-S-D-A measures 0.360" (9.14mm) while TFM-105-32-S-D-A measures 0.435" (11.05mm). All electrical parameters, contact ratings, and operating specifications are identical. The TFM-105-32-S-D-A is selected when additional board clearance is required.

Q: Is 5-104693-1 compatible with applications designed for TFM-105-22-S-D-A?

A: Compatibility depends on current requirements. The 5-104693-1 is rated for 0.5A per contact, compared to 2.9A for the TFM-105-22-S-D-A. If the application requires current exceeding 0.5A per contact, this substitute is not suitable. Additionally, the operating temperature range is narrower (-65°C ~ 105°C vs. -55°C ~ 125°C). Verify application current and temperature requirements before selection.

Q: Do all substitute parts maintain the same pitch and row spacing?

A: Yes. All identified substitutes maintain 0.050" (1.27mm) pitch and 0.050" (1.27mm) row spacing, ensuring mechanical compatibility with mating connectors designed for the TFM-105-22-S-D-A.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TFM-105-12-S-D-A, 5-104693-1, and TFM-105-32-S-D-A are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the TFM-105-22-S-D-A.

Q: What is the difference in contact shape between substitutes?

A: TFM-105-22-S-D-A, TFM-105-12-S-D-A, and TFM-105-32-S-D-A feature square contact shapes. The 5-104693-1 features circular contacts. Contact shape does not affect electrical performance but may influence mating force and connector durability characteristics.

Q: Which substitute offers the best inventory availability?

A: TFM-105-12-S-D-A has the highest inventory (2506 pcs), followed by 5-104693-1 (1474 pcs), TFM-105-32-S-D-A (1201 pcs), and TFM-105-22-S-D-A (943 pcs).
