Substitute Part Grouping Explanation

Substitute parts for the TFM-115-23-S-D are identified within the Tiger Eye™ TFM series based on electrical and mechanical compatibility. The primary substitution criteria are:

• Identical connector type (Header), contact type (Male Pin), and pitch specifications (0.050" / 1.27mm)
• Matching number of positions (30) and row configuration (2 rows)
• Compatible mounting method (Through Hole) and termination (Solder)
• Identical shrouding design (Shrouded - 4 Wall)
• Equivalent electrical ratings (2.9A per Contact, 275VAC)
• Matching operating temperature range (-55°C ~ 125°C)
• Identical contact material (Phosphor Bronze) and finish specifications (Gold mating, Tin post)
• Compliance with UL94 V-0 flammability rating

The identified substitutes differ only in insulation height and specific feature designations, which do not affect core electrical or mechanical compatibility for standard board-to-board connection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TFM-115-23-S-D, TFM-115-03-S-D, and TFM-115-03-S-D-WT—are active products from Samtec Inc. and maintain full ROHS3 compliance. Selection between these parts depends on application-specific requirements for insulation height and mechanical features.

The TFM-115-23-S-D features an insulation height of 0.360" (9.14mm) and is suitable for applications requiring greater standoff distance from the PCB. The TFM-115-03-S-D and TFM-115-03-S-D-WT both feature a reduced insulation height of 0.220" (5.60mm), accommodating space-constrained designs. The TFM-115-03-S-D-WT variant includes solder retention as a specified feature, providing additional mechanical stability during assembly processes.

All parts maintain identical electrical performance (2.9A per Contact, 275VAC), contact specifications, and thermal operating range (-55°C ~ 125°C). PCB layout and mating connector compatibility must be evaluated based on the selected insulation height to ensure proper mechanical fit and electrical performance.

Frequently Asked Questions (FAQ)

Q: Can TFM-115-03-S-D and TFM-115-03-S-D-WT be used interchangeably with TFM-115-23-S-D?

A: Electrical and contact specifications are identical across all three parts. Substitution is mechanically feasible only if the application PCB layout accommodates the reduced insulation height of 0.220" (5.60mm) for the TFM-115-03 variants, compared to 0.360" (9.14mm) for the TFM-115-23-S-D. Verify mating connector clearance and PCB trace routing before substitution.

Q: What is the difference between TFM-115-03-S-D and TFM-115-03-S-D-WT?

A: Both parts are electrically and mechanically identical with matching insulation height (0.220" / 5.60mm). The TFM-115-03-S-D-WT includes solder retention as a specified feature, which provides enhanced mechanical stability during wave or reflow soldering processes. Selection depends on assembly process requirements and design specifications.

Q: Are all three parts RoHS compliant?

A: Yes. TFM-115-23-S-D, TFM-115-03-S-D, and TFM-115-03-S-D-WT are all ROHS3 compliant. Moisture sensitivity level for TFM-115-23-S-D is rated as 1 (Unlimited), while TFM-115-03 variants are rated as Not Applicable.

Q: What are the electrical ratings for these connectors?

A: All three parts are rated for 2.9A per contact and 275VAC maximum voltage. Operating temperature range is -55°C to 125°C across all variants. Contact material is phosphor bronze with gold plating (30.0µin / 0.76µm) on mating surfaces and tin plating on post terminations.

Q: Are these parts suitable for high-reliability applications?

A: All three parts meet UL94 V-0 flammability rating and are manufactured by Samtec Inc. with active product status. Compliance certifications and material specifications support use in industrial and commercial applications. Application-specific reliability requirements must be evaluated independently.
