Contact Length Consideration: Samtec substitute parts feature contact length of 0.131" (3.33mm) compared to 0.120" (3.05mm) on the TE Connectivity part. This 0.011" (0.28mm) difference is within acceptable tolerance for board-to-board mating applications.

Operating Temperature Range: Samtec substitutes operate across -55°C ~ 125°C, providing extended upper temperature capability compared to the TE Connectivity part (-65°C ~ 105°C). The lower temperature limit is -55°C versus -65°C on the primary part.

Frequently Asked Questions (FAQ)

Q: Can Samtec Tiger Eye™ TFC and TFM series connectors directly replace the TE Connectivity 5-147381-4?

A: Yes, within the specified electrical and mechanical parameters. Both series maintain identical pitch (0.050"), position count (40), row configuration (2), shrouding (4-wall), termination (solder), and fastening (push-pull). Contact material, insulation material, and flammability rating are identical. Differences in contact length (0.011" longer on Samtec parts) and insulation height (0.006" shorter on TFM series) are within acceptable tolerances for board-to-board applications.

Q: What is the primary difference between Samtec TFC and TFM series?

A: The TFC series provides higher current rating (3.1A per contact) and maintains insulation height of 0.226" (5.74mm), matching the TE Connectivity part. The TFM series provides 2.9A per contact with insulation height of 0.220" (5.60mm). Both series support board-to-board or cable configurations. Feature options differ between series, with TFC offering Board Guide and TFM offering Board Lock or Board Guide combinations.

Q: Are there packaging format options for substitute parts?

A: Yes. Samtec TFC series is available in Cut Tape (CT), Tube, and Tape & Reel (TR) formats. Samtec TFM series is available in Tube and Tape & Reel (TR) formats. The primary TE Connectivity part is supplied in Tape & Reel format. Selection of packaging format depends on assembly process requirements and volume specifications.

Q: What is the significance of the contact finish thickness variation?

A: Contact finish thickness varies across substitute parts: TE Connectivity 5-147381-4 specifies 30.0µin (0.76µm), Samtec TFC-120-02-F-D-A-K-TR specifies 3.00µin (0.076µm), Samtec TFC-120-02-L-D-A-K and TFC-120-02-L-D-A-K-TR specify 10.0µin (0.25µm), and Samtec TFM series specifies 15.0µin (0.38µm). All values provide adequate gold plating for reliable mating contact performance. Thicker plating on the primary part provides extended contact life in high-cycle mating applications.

Q: Do substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 Compliant, which exceeds the RoHS Compliant status of the primary part. All parts carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. ECCN classification is EAR99 for all parts, and HTSUS code is 8536.69.4040 for all parts.

Q: What is the impact of the extended operating temperature range on substitute parts?

A: Samtec substitute parts operate across -55°C ~ 125°C, compared to -65°C ~ 105°C on the TE Connectivity part. The upper temperature limit is extended by 20°C, providing capability for higher-temperature applications. The lower temperature limit is reduced by 10°C. Applications requiring operation below -55°C must use the TE Connectivity part or confirm compatibility with Samtec technical documentation.

Q: How do feature options (Board Lock, Board Guide, Pick and Place) affect substitution?

A: Feature options do not affect electrical or mechanical compatibility. Board Lock provides mechanical retention during assembly. Board Guide aids in connector alignment during mating. Pick and Place indicates suitability for automated assembly equipment. Selection of feature options depends on assembly process requirements and mechanical retention needs. The primary TE Connectivity part includes Board Lock and Pick and Place features.
