TFM-115-22-S-D Equivalent & Substitute Parts

Part Overview

The TFM-115-22-S-D is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This 30-position, 2-row connector operates at 0.050" (1.27mm) pitch and is designed for board-to-board or cable applications with push-pull fastening. The part is currently active in production with 618 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications align with the original design requirements, enabling component interchangeability in applications where the primary part becomes unavailable or when alternative sourcing is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-115-22-S-D is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 30 positions in 2-row arrangement
• Pitch Specification: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Shrouding & Fastening: 4-wall shrouded design with push-pull fastening
• Material & Finish Compliance: Phosphor bronze contacts with gold mating finish and tin post finish; LCP insulation material
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The substitute part 5-104693-3 (TE Connectivity AMP Connectors AMPMODU 50/50 Grid series) meets these core substitution criteria through identical position count, pitch, mounting type, shrouding configuration, fastening mechanism, and material specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-115-22-S-D and 5-104693-3 are active production parts with ROHS3 compliance and EAR99 export classification. The parts share identical mechanical and electrical interface specifications including connector type, position count, pitch, mounting technology, and contact materials.

Differences in contact length, insulation height, current rating, voltage rating, and operating temperature range exist between the two parts. Selection between these parts depends on application-specific electrical requirements. The TFM-115-22-S-D supports higher current per contact (2.9A versus 0.5A) and higher voltage rating (275VAC), while the 5-104693-3 operates across a wider low-temperature range (-65°C versus -55°C minimum). Both parts maintain MSL 1 rating and unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the 5-104693-3 directly replace the TFM-115-22-S-D in all applications?

A: Direct replacement depends on application electrical requirements. Both parts share identical mechanical interfaces (30 positions, 0.050" pitch, 2-row configuration, surface mount, push-pull fastening). However, the 5-104693-3 has lower current rating per contact (0.5A versus 2.9A) and unspecified voltage rating compared to the TFM-115-22-S-D (275VAC). Applications requiring the higher current or voltage specifications of the original part may not be suitable for the substitute.

Q: Are there physical footprint differences between these parts?

A: Contact length and insulation height differ between the parts. The TFM-115-22-S-D has a contact mating length of 0.139" (4.63mm) and insulation height of 0.360" (9.14mm), while the 5-104693-3 has a contact mating length of 0.120" (3.05mm) and insulation height of 0.367" (9.33mm). These dimensional variations may affect mating depth and board layout considerations.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS code (8536.69.4040). Both maintain MSL 1 rating with unlimited moisture sensitivity shelf life. Material flammability rating is UL94 V-0 for both parts.

Q: What is the difference in operating temperature ranges?

A: The TFM-115-22-S-D operates from -55°C to 125°C, while the 5-104693-3 operates from -65°C to 105°C. The substitute part supports lower minimum temperatures but has a lower maximum temperature limit. Application thermal requirements determine suitability.

Q: Are the contact materials and finishes identical?

A: Both parts use phosphor bronze contacts with gold mating finish (30.0µin thickness) and tin post finish. Contact material and mating finish specifications are identical between the two parts.
