FTS-112-02-LM-D Equivalent & Substitute Parts

Part Overview

The FTS-112-02-LM-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical connector features 24 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing and is classified as cuttable. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating.

Substitute parts are identified when electrical and mechanical parameters remain within the allowed specifications for this connector category. Alternatives may be required due to inventory availability, specific packaging requirements, or design-specific features such as pick-and-place compatibility or increased insulation height.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FTS-112-02-LM-D are qualified based on the following critical parameters that must remain constant:

• Number of Positions: 24
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Current Rating: 3.4A per Contact
• Operating Temperature: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

Variations permitted in substitute parts include series designation (FTS vs. FTSH), overall contact length, insulation height, and optional features such as pick-and-place compatibility. These variations do not affect electrical or mechanical compatibility in board-to-board or cable applications where the mating pitch and contact specifications are preserved.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain identical electrical and mechanical specifications for mating pitch, contact configuration, current rating, and operating temperature range. Selection between FTS-112-02-LM-D and its substitutes is determined by application-specific requirements:

FTS-112-02-L-D provides direct electrical and mechanical equivalence with identical overall contact length and insulation height. This part is suitable for applications requiring standard through-hole solder termination without specialized handling requirements.

FTS-112-02-L-D-P includes pick-and-place feature designation, indicating compatibility with automated assembly processes. This variant maintains all electrical specifications while accommodating high-volume manufacturing workflows.

FTSH-112-02-L-D belongs to the FTSH series and features increased overall contact length (0.265" vs. 0.199") and insulation height (0.099" vs. 0.034"). This variant is specified for applications requiring extended post length or increased insulation clearance. Board layout and mating connector specifications must accommodate these dimensional differences.

All parts carry active product status, ROHS3 compliance, and UL94 V-0 flammability certification, confirming suitability for current design requirements and regulatory environments.

Frequently Asked Questions (FAQ)

Q: Can FTS-112-02-L-D be used as a direct replacement for FTS-112-02-LM-D?

A: Yes. Both parts share identical electrical and mechanical parameters including mating pitch, contact configuration, current rating, and operating temperature. The primary difference is series designation within the FTS family. Electrical compatibility and board-level integration are equivalent.

Q: What is the significance of the pick-and-place feature in FTS-112-02-L-D-P?

A: The pick-and-place designation indicates the part is optimized for automated assembly equipment. This feature does not alter electrical or mechanical specifications. Selection of this variant depends on manufacturing process requirements, not application performance.

Q: When should FTSH-112-02-L-D be selected instead of FTS variants?

A: FTSH-112-02-L-D is specified when increased overall contact length (0.265" vs. 0.199") or insulation height (0.099" vs. 0.034") is required by board layout or mating connector design. Verify that PCB footprint and connector cavity depth accommodate the extended dimensions before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FTS-112-02-LM-D, FTS-112-02-L-D, FTS-112-02-L-D-P, and FTSH-112-02-L-D all carry ROHS3 compliance certification. All parts meet current environmental and regulatory requirements.

Q: What is the current rating per contact for these connectors?

A: All parts are rated for 3.4A per contact. Total system current capacity depends on the number of loaded positions and circuit design. Verify that application current distribution does not exceed per-contact ratings.

Q: Do these connectors support the same operating temperature range?

A: Yes. All four parts operate across -55°C to 125°C. Temperature derating requirements depend on application environment and current loading. Consult thermal analysis for specific operating conditions.
