Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFM-145 base product family is determined by the following invariant parameters:

• Connector type (Receptacle)
• 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)
• Termination (Solder)
• Contact finish - mating (Gold, 30.0µin)
• Current rating (3.2A per Contact)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability (UL94 V-0)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)
• RoHS status (ROHS3 Compliant)
• Moisture sensitivity level (1)

Substitute parts differ only in fastening features (Board Lock, Board Guide, Pick and Place) and contact post finish specifications, which do not affect electrical or thermal performance in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain identical electrical, thermal, and compliance specifications with the SFM-145-T2-S-D. Selection among these equivalents is based on mechanical assembly requirements:

SFM-145-02-S-D-LC and SFM-145-L2-S-D-LC include Board Lock features for applications requiring positive mechanical retention during mating cycles.

SFM-145-02-SM-D-A-P incorporates Board Guide and Pick and Place features, suitable for automated assembly processes requiring component positioning assistance.

SFM-145-02-S-D-A includes Board Guide features for manual or semi-automated assembly applications.

All parts are active in production status with ROHS3 compliance and unlimited moisture sensitivity rating. Inventory availability varies across the substitute options.

Frequently Asked Questions (FAQ)

Q: Can SFM-145-02-S-D-LC be used as a direct replacement for SFM-145-T2-S-D?

A: Yes. Both connectors share identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), contact configuration (90 positions, 0.050" pitch), and compliance certifications (ROHS3, UL94 V-0). The Board Lock feature in SFM-145-02-S-D-LC provides additional mechanical retention without affecting electrical performance.

Q: What is the difference between Board Lock and Board Guide features?

A: Board Lock provides positive mechanical retention to prevent accidental disconnection during mating. Board Guide assists with component alignment during assembly. Both are mechanical features that do not alter electrical or thermal characteristics.

Q: Are all substitute parts surface mount compatible?

A: Yes. All listed substitute parts are surface mount receptacles with identical solder termination and mounting specifications.

Q: Do substitute parts have different contact ratings?

A: No. All substitute parts maintain 3.2A per contact current rating and 250VAC voltage rating. Contact material (Beryllium Copper) and finish (Gold, 30.0µin) are identical across all options.

Q: Which substitute part is recommended for automated assembly?

A: SFM-145-02-SM-D-A-P includes Pick and Place features designed to support automated assembly processes.

Q: Are there temperature or compliance differences between substitute parts?

A: No. All substitute parts operate across the identical temperature range (-55°C ~ 125°C) and maintain ROHS3 compliance with UL94 V-0 flammability rating.
