TFM-107-02-S-S-WT Equivalent & Substitute Parts

Part Overview

The TFM-107-02-S-S-WT is a surface mount rectangular connector header manufactured by Samtec Inc. as part of the Tiger Eye™ TFM series. This 7-position, single-row connector operates at 1.27mm pitch and is designed for board-to-board or cable applications with push-pull fastening. The part is currently active in production and widely available in inventory. Alternative components may be required due to design constraints, availability fluctuations, or specific application requirements that demand different electrical or mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TFM-107-02-S-S-WT is evaluated based on the following critical parameters that define functional compatibility:

Pitch Compatibility: The mating pitch of 0.050" (1.27mm) is the primary constraint for mechanical interchangeability. Substitute parts must maintain this pitch to ensure proper mating with corresponding receptacles.

Mounting and Termination: Surface mount solder termination is required to match the original part's PCB integration method.

Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements. The TFM-107-02-S-S-WT provides 2.9A per contact at 275VAC.

Environmental Compliance: RoHS and REACH compliance status, along with operating temperature range and flammability rating, must align with regulatory and application requirements.

Connector Configuration: The 7-position, single-row, shrouded header with push-pull fastening defines the physical and functional interface.

The substitute part 20021221-00014T4LF shares the 1.27mm pitch and surface mount solder termination but differs in position count (14 vs. 7), row configuration (2 rows vs. 1 row), and electrical ratings (1A per contact at 125VAC vs. 2.9A per contact at 275VAC). This part is suitable only for applications where the higher position count and dual-row configuration are acceptable and where the lower current and voltage ratings are sufficient.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-107-02-S-S-WT and 20021221-00014T4LF are active production components with UL94 V-0 flammability ratings and unlimited moisture sensitivity levels. Both comply with RoHS standards and operate across the -55°C to 125°C temperature range.

The TFM-107-02-S-S-WT is the primary choice for applications requiring 7 positions in a single-row configuration with higher electrical capacity (2.9A per contact, 275VAC). This part offers ROHS3 compliance and is manufactured from Liquid Crystal Polymer insulation with phosphor bronze contacts.

The 20021221-00014T4LF serves as a substitute only in applications where the 14-position, dual-row configuration is compatible with the PCB layout and where the reduced electrical ratings (1A per contact, 125VAC) are acceptable. This part uses thermoplastic insulation and copper alloy contacts. REACH status differs between the two parts, with the substitute being REACH Affected compared to the main part's REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 20021221-00014T4LF directly replace the TFM-107-02-S-S-WT?

A: Direct replacement is not possible due to fundamental differences in position count and row configuration. The TFM-107-02-S-S-WT is a 7-position single-row header, while the 20021221-00014T4LF is a 14-position dual-row header. PCB footprints and mating receptacles are incompatible between these configurations.

Q: Are the electrical ratings compatible?

A: No. The TFM-107-02-S-S-WT supports 2.9A per contact at 275VAC, while the 20021221-00014T4LF supports only 1A per contact at 125VAC. Applications requiring the higher current or voltage ratings of the main part cannot use the substitute.

Q: Do both parts share the same mating pitch?

A: Yes. Both parts operate at 0.050" (1.27mm) pitch, which is the standard spacing for 1.27mm connector families. This is a shared characteristic but does not enable substitution due to the position and row configuration differences.

Q: What are the compliance differences?

A: Both parts are RoHS compliant and UL94 V-0 rated. The main part is ROHS3 Compliant and REACH Unaffected, while the substitute is RoHS Compliant and REACH Affected. Applications subject to REACH regulations may require the main part.

Q: Are the insulation materials interchangeable?

A: The materials differ. The TFM-107-02-S-S-WT uses Liquid Crystal Polymer (LCP) insulation, while the 20021221-00014T4LF uses thermoplastic insulation. LCP offers superior thermal and mechanical properties in high-reliability applications.

Q: Can I use the substitute in a high-current application?

A: No. The substitute's 1A per contact rating is insufficient for applications designed around the main part's 2.9A per contact capacity. Current derating and thermal management would be compromised.
