SFM-140-02-L-D-A-P-TR Equivalent & Substitute Parts

Part Overview

The SFM-140-02-L-D-A-P-TR is an 80-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating, gold-plated female socket contacts, and push-pull fastening. The part is Active status and widely used in high-density interconnect applications requiring reliable electrical performance across industrial temperature ranges.

Identifying equivalent and substitute parts is necessary when the primary packaging format (Tape & Reel) is unavailable or when alternative distribution methods better suit procurement requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

The SFM-140-02-L-D-A-P-TR has one identified substitute part: SFM-140-02-L-D-A-K-TR. Both parts share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility:

• Connector type, contact configuration, and position count (80-position receptacle, female socket)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Surface mount termination and fastening method (solder, push-pull)
• Contact material, finish type, and thickness (beryllium copper, gold 10.0µin)
• Current and voltage ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material and flammability rating (LCP, UL94 V-0)
• RoHS3 compliance and MSL rating (1 - Unlimited)

The sole difference between these parts is packaging format: SFM-140-02-L-D-A-P-TR is supplied in Tape & Reel (TR), while SFM-140-02-L-D-A-K-TR is supplied in Cut Tape (CT). Both originate from the same base product number (SFM-140) and series.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-140-02-L-D-A-P-TR and SFM-140-02-L-D-A-K-TR are Active status products from Samtec Inc. and are fully equivalent for electrical and mechanical applications. Selection between these parts should be based on packaging and procurement requirements:

• SFM-140-02-L-D-A-P-TR (Tape & Reel) is suitable for high-volume automated assembly operations where reel-fed pick-and-place equipment is utilized.
• SFM-140-02-L-D-A-K-TR (Cut Tape) is suitable for lower-volume production runs, prototyping, or manual assembly workflows where individual component handling is preferred.

Both parts maintain identical compliance certifications: ROHS3 compliance, UL94 V-0 flammability rating, EAR99 export classification, and MSL 1 (Unlimited) moisture sensitivity level. Electrical performance, thermal characteristics, and mechanical dimensions are identical across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Are SFM-140-02-L-D-A-P-TR and SFM-140-02-L-D-A-K-TR electrically interchangeable?

A: Yes. Both parts are electrically and mechanically identical. They share the same contact configuration, pitch, current rating (3.2A per contact), voltage rating (250VAC), operating temperature range (-55°C ~ 125°C), and all other functional specifications. The only difference is packaging format.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging supplies components on tape segments cut to specific lengths, typically used for lower-volume or manual assembly processes. Both formats contain the same component.

Q: Can I use Cut Tape (CT) packaging in automated assembly equipment designed for Tape & Reel (TR)?

A: Cut Tape is not compatible with standard reel-fed pick-and-place equipment. Automated assembly systems require continuous reel format. Cut Tape components must be manually loaded or processed through different handling equipment.

Q: Are there any compliance or certification differences between these two parts?

A: No. Both parts carry identical certifications: ROHS3 compliance, UL94 V-0 flammability rating, EAR99 export classification, and MSL 1 (Unlimited) rating. Compliance status is independent of packaging format.

Q: Which part should I select for my application?

A: Selection depends on your assembly process. For automated high-volume production, use SFM-140-02-L-D-A-P-TR (Tape & Reel). For prototyping, low-volume production, or manual assembly, use SFM-140-02-L-D-A-K-TR (Cut Tape). Both deliver identical electrical and mechanical performance.

Q: Are the mated stacking heights the same for both parts?

A: Yes. Both parts support identical mated stacking heights: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm.
