Samtec TFM-115-22-SM-D-A Equivalent & Substitute Parts

Part Overview

The Samtec TFM-115-22-SM-D-A is an active surface mount rectangular connector header from the Tiger Eye™ TFM series. This 30-position, 2-row shrouded header operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications. The part is actively manufactured and stocked, with 751 units available. Substitute parts are identified based on matching electrical specifications, mechanical compatibility within the TFM-115 base product family, and identical connector architecture while accommodating variations in insulation height.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the TFM-115 family are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain identical pitch (0.050" / 1.27mm), position count (30), row configuration (2 rows), contact type (male pin), current rating (2.9A per contact), voltage rating (275VAC), and operating temperature range (-55°C ~ 125°C).

Mechanical Compatibility: All parts share the same shrouding style (shrouded 4-wall), mounting type (surface mount), termination method (solder), contact material (phosphor bronze), contact finish (gold mating surface), and insulation material (LCP).

Variation Parameter: The primary differentiator among substitute parts is insulation height, which varies across the TFM-115 family:

• TFM-115-22-SM-D-A: 0.360" (9.14mm) insulation height
• TFM-115-12-S-D-A: 0.290" (7.37mm) insulation height
• TFM-115-22-S-D-A: 0.360" (9.14mm) insulation height
• TFM-115-32-S-D-A: 0.435" (11.05mm) insulation height

Insulation height selection depends on PCB stackup requirements and mating connector specifications. All parts are active products with ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All four parts are active products manufactured by Samtec Inc. and carry ROHS3 compliance with MSL 1 rating, indicating full regulatory alignment and unlimited shelf life under standard storage conditions.

Selection among TFM-115 family variants is determined by PCB design requirements:

TFM-115-22-SM-D-A (0.360" insulation height): Primary specification with 751 units in stock. Suitable for standard board stackup applications requiring mid-range insulation height.

TFM-115-12-S-D-A (0.290" insulation height): Lowest profile option with highest inventory (1144 units). Applicable to space-constrained designs or thin PCB assemblies.

TFM-115-22-S-D-A (0.360" insulation height): Electrically and mechanically identical to the main part with 731 units available. Functionally interchangeable for applications with identical PCB height requirements.

TFM-115-32-S-D-A (0.435" insulation height): Tallest profile with 992 units in stock. Required for applications with thicker PCB stackups or higher mating connector profiles.

All parts maintain identical electrical performance (2.9A per contact, 275VAC), thermal range (-55°C ~ 125°C), and contact architecture. Substitution is valid when insulation height compatibility is confirmed with mating connector specifications and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can TFM-115-22-SM-D-A be directly replaced with TFM-115-22-S-D-A?

A: Yes. Both parts have identical insulation height (0.360" / 9.14mm), electrical ratings, contact configuration, and material specifications. They are functionally interchangeable for applications with matching PCB stackup requirements.

Q: What determines which TFM-115 variant to select?

A: Insulation height is the primary selection criterion. The height must accommodate the mating connector profile and PCB assembly thickness. Electrical and mechanical specifications are identical across all variants.

Q: Are all TFM-115 variants compatible with the same mating connectors?

A: Mating connector compatibility depends on the mating connector's insulation height specification. Each TFM-115 variant is designed to mate with connectors specifying its corresponding insulation height. Verify mating connector documentation for required insulation height before substitution.

Q: What is the difference between SM and S designations in the part number?

A: The part number suffix indicates design variations within the TFM-115 family. Both SM and S variants maintain identical electrical and core mechanical specifications. Substitution is valid when insulation height requirements are met.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts carry ROHS3 compliance and MSL 1 rating, confirming regulatory alignment and unlimited moisture sensitivity shelf life.

Q: What is the current rating per contact across all variants?

A: All TFM-115 family parts are rated at 2.9A per contact with a 275VAC voltage rating, regardless of insulation height variant.
