TFML-150-02-S-D Equivalent & Substitute Parts

Part Overview

The TFML-150-02-S-D is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFML series. This 100-position, dual-row connector operates at 0.050" (1.27mm) pitch and features shrouded 4-wall construction with friction lock fastening. The part is Active status and ROHS3 compliant, designed for board-to-board or cable applications in industrial and commercial environments.

Substitute parts are identified to provide design flexibility when the primary part is unavailable, when inventory requirements exceed stock levels, or when alternative mechanical features better suit specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFML-150-02-S-D is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type: Header
• Contact type: Male pin
• Number of positions: 100
• 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
• Termination: Solder
• Contact finish - mating: Gold
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Secondary Variation Parameters (Allowable Differences):

• Fastening type (friction lock vs. push-pull)
• Mechanical features (board guide, board lock)
• Insulation material (LCP vs. thermoplastic, glass filled)
• Insulation color
• Contact material specification
• Operating temperature upper limit (125°C vs. 130°C)
• Manufacturer and series designation

All three identified substitute parts meet the primary substitution criteria. Variations in secondary parameters reflect design options within the same functional class and do not preclude interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and meet UL94 V-0 flammability requirements. The three Samtec Tiger Eye™ TFML variants (TFML-150-02-S-D, TFML-150-02-S-D-LC, TFML-150-02-S-D-A) are ROHS3 compliant and feature identical electrical and mechanical core specifications. The Amphenol ICC 87409-150LF is RoHS compliant and offers extended operating temperature capability to 130°C.

Selection between Samtec variants depends on mechanical feature requirements: the base TFML-150-02-S-D provides standard friction lock fastening; TFML-150-02-S-D-A adds board guide functionality; TFML-150-02-S-D-LC incorporates board lock capability. The 87409-150LF substitutes friction lock with push-pull fastening and uses thermoplastic glass-filled insulation instead of LCP, with marginally different contact length and insulation height specifications.

Frequently Asked Questions (FAQ)

Q: Can TFML-150-02-S-D be directly replaced with 87409-150LF?

A: Yes, within the constraints of fastening type compatibility. The 87409-150LF uses push-pull fastening versus the friction lock design of TFML-150-02-S-D. Both maintain 100-position, dual-row, 0.050" pitch configuration with identical contact finish specifications and UL94 V-0 rating. Verify mating connector compatibility with the push-pull mechanism before substitution.

Q: What is the difference between TFML-150-02-S-D and TFML-150-02-S-D-LC?

A: The TFML-150-02-S-D-LC incorporates board lock mechanical features compared to the standard TFML-150-02-S-D. All other electrical and thermal specifications are identical. The board lock feature provides additional mechanical retention during mating operations.

Q: Are all substitute parts ROHS compliant?

A: Yes. TFML-150-02-S-D, TFML-150-02-S-D-LC, and TFML-150-02-S-D-A are ROHS3 compliant. The 87409-150LF is RoHS compliant. All parts meet regulatory requirements for lead-free construction.

Q: What is the operating temperature difference between Samtec and Amphenol variants?

A: Samtec Tiger Eye™ TFML series parts operate from -55°C to 125°C. The Amphenol ICC 87409-150LF extends the upper limit to 130°C. Select the Amphenol variant for applications requiring operation above 125°C.

Q: Do all parts have the same contact finish specifications?

A: Yes. All four parts feature gold mating contact finish at 30.0µin (0.76µm) thickness and tin post finish. Contact material differs: Samtec parts use phosphor bronze; Amphenol ICC material specification is not provided in the data.

Q: What inventory levels are available for each part?

A: TFML-150-02-S-D: 829 pcs; TFML-150-02-S-D-LC: 802 pcs; TFML-150-02-S-D-A: 630 pcs; 87409-150LF: 1273 pcs. The 87409-150LF offers the highest current stock availability.

Q: Are mechanical dimensions identical across all substitutes?

A: Contact length and insulation height vary slightly. TFML-150-02-S-D, TFML-150-02-S-D-LC, and TFML-150-02-S-D-A share identical dimensions: 0.134" (3.39mm) contact length and 0.220" (5.60mm) insulation height. The 87409-150LF measures 0.130" (3.30mm) contact length and 0.226" (5.74mm) insulation height. Verify PCB layout compatibility before substituting the Amphenol part.
