SFM-145-02-S-D-A-P Equivalent & Substitute Parts

Part Overview

The SFM-145-02-S-D-A-P is a 90-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating with gold-plated female socket contacts rated for 3.2A per contact at 250VAC. The part is currently active in production with full inventory availability.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, ensuring functional interchangeability within the same series while accommodating specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SFM-145 series is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (90)
• Pitch configuration (0.050" mating pitch, 0.050" row spacing)
• Mounting method (Surface Mount)
• Electrical ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold mating surface)
• Insulation material (Liquid Crystal Polymer)
• Compliance certifications (UL94 V-0, ROHS3)

The identified substitute part maintains all these parameters while differing only in specific post-contact finish or internal configuration details that do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-145-02-S-D-A-P and SFM-145-02-SM-D-A-P are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Both maintain identical electrical specifications, mechanical dimensions, and environmental operating parameters. Selection between these parts should be based on application-specific requirements and current inventory availability. The SFM-145-02-S-D-A-P currently maintains higher stock levels at 1086 units, while the SFM-145-02-SM-D-A-P is available with 807 units in inventory.

Frequently Asked Questions (FAQ)

Q: Are SFM-145-02-S-D-A-P and SFM-145-02-SM-D-A-P electrically interchangeable?

A: Yes. Both parts maintain identical electrical ratings of 3.2A per contact at 250VAC, identical contact materials (Beryllium Copper with gold mating finish), and identical operating temperature ranges (-55°C ~ 125°C).

Q: What determines substitutability within the SFM-145 series?

A: Substitutability is determined by equivalence in connector type, contact type, position count, pitch configuration, mounting method, electrical ratings, operating temperature, contact finish specifications, insulation material, and compliance certifications. Variations in post-contact finish or internal configuration details do not affect functional interchangeability.

Q: Are there any mechanical differences between these parts?

A: Both parts share identical mechanical specifications including 90 positions, 0.050" (1.27mm) mating pitch, 2-row configuration, 0.185" (4.70mm) insulation height, and identical mated stacking heights (6.15mm through 11.76mm).

Q: Do both parts support the same mounting and termination methods?

A: Yes. Both are surface mount connectors with solder termination and push-pull fastening type. Both include board guide and pick-and-place features.

Q: Are both parts RoHS compliant?

A: Yes. Both SFM-145-02-S-D-A-P and SFM-145-02-SM-D-A-P are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
