Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TFM-145-02-S-D is determined by strict equivalence across the following critical parameters:

• Manufacturer Part Number base designation (TFM-145)
• Number of Positions (90)
• Pitch - Mating (0.050" / 1.27mm)
• Number of Rows (2)
• Row Spacing - Mating (0.050" / 1.27mm)
• Mounting Type (Surface Mount)
• Contact Type (Male Pin)
• Connector Type (Header)
• Termination method (Solder)
• Fastening Type (Push-Pull)
• Insulation Material (Liquid Crystal Polymer)
• Current Rating (2.9A per Contact)
• Voltage Rating (275VAC)
• Operating Temperature range (-55°C ~ 125°C)
• Material Flammability Rating (UL94 V-0)
• RoHS Compliance (ROHS3 Compliant)

The identified substitute part TFM-145-02-S-D-A maintains full electrical and mechanical compatibility with the primary part while introducing an additional Board Guide feature. This feature addition does not alter the core substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

Both TFM-145-02-S-D and TFM-145-02-S-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on application-specific requirements:

The TFM-145-02-S-D-A includes a Board Guide feature that provides additional mechanical alignment during mating operations. This feature does not affect electrical performance, current capacity, voltage rating, or thermal operating range.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification. Both are classified as MSL 1 (Unlimited moisture sensitivity level), indicating no special storage or handling requirements.

Selection of the substitute part TFM-145-02-S-D-A is appropriate when board guide functionality enhances assembly reliability or when the primary part is unavailable. Direct substitution is electrically and mechanically valid in all applications designed for the TFM-145-02-S-D.

Frequently Asked Questions (FAQ)

Q: Can TFM-145-02-S-D-A be used as a direct replacement for TFM-145-02-S-D?

A: Yes. The TFM-145-02-S-D-A is a direct electrical and mechanical substitute. The only difference is the addition of a Board Guide feature on the substitute part. This feature provides enhanced alignment during mating and does not affect electrical performance or compatibility.

Q: What is the significance of the Board Guide feature in TFM-145-02-S-D-A?

A: The Board Guide is a mechanical alignment aid that assists in proper connector positioning during mating operations. It does not alter electrical specifications, current capacity, voltage rating, or operating temperature range.

Q: Are both parts suitable for the same PCB layout and footprint?

A: Yes. Both TFM-145-02-S-D and TFM-145-02-S-D-A share identical pitch (0.050" / 1.27mm), position count (90), row configuration (2 rows), and mounting type (Surface Mount). PCB footprints are compatible.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: number of positions (90), mating pitch (0.050" / 1.27mm), number of rows (2), row spacing (0.050" / 1.27mm), mounting type (Surface Mount), contact type (Male Pin), termination method (Solder), fastening type (Push-Pull), current rating (2.9A per Contact), and voltage rating (275VAC).

Q: Do both parts require special handling or storage?

A: No. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage practices apply.

Q: Are both parts RoHS compliant?

A: Yes. Both TFM-145-02-S-D and TFM-145-02-S-D-A are ROHS3 compliant and carry UL94 V-0 flammability certification.
