Substitute Part Grouping Explanation

Substitute parts for the SFM-125-02-S-D-A-P are identified based on the following critical parameters that determine functional interchangeability:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 50 positions at 0.050" (1.27mm) mating pitch
• Row Configuration: 2 rows with 0.050" (1.27mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Finish: Gold-plated mating surface
• Insulation Material: Liquid Crystal Polymer (LCP)
• Compliance: ROHS3 compliant with MSL 1 rating

The substitute part 5-104652-5 (TE Connectivity AMP Connectors AMPMODU 50/50 Grid series) meets all critical substitution parameters. Both connectors share identical position count, pitch, row configuration, mounting type, termination method, fastening type, contact finish material, and insulation material.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-125-02-S-D-A-P and 5-104652-5 are active production parts with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on:

• Supply Chain Availability: The 5-104652-5 maintains higher inventory levels (70,100 pcs vs. 909 pcs), providing greater availability for high-volume applications.
• Mechanical Features: The SFM-125-02-S-D-A-P includes board guide and pick-and-place features; the 5-104652-5 includes board lock feature. Design requirements should determine which mechanical feature set is appropriate.
• Mated Stacking Heights: The SFM-125-02-S-D-A-P offers five stacking height options (6.15mm through 11.76mm); the 5-104652-5 offers three options (6.35mm, 8.13mm, 9.91mm). PCB stack-up requirements should guide selection.
• Electrical Ratings: The SFM-125-02-S-D-A-P specifies 3.2A per contact and 250VAC rating. The 5-104652-5 does not provide these specifications in available documentation.
• Operating Temperature Range: The SFM-125-02-S-D-A-P operates from -55°C to 125°C; the 5-104652-5 operates from -65°C to 105°C. Temperature environment requirements should determine suitability.

Frequently Asked Questions (FAQ)

Q: Can the 5-104652-5 be used as a direct replacement for the SFM-125-02-S-D-A-P?

A: The 5-104652-5 meets all critical substitution parameters including position count, pitch, row configuration, mounting type, termination method, fastening type, contact finish, and insulation material. However, differences in mechanical features (board guide vs. board lock), stacking height options, and operating temperature range must be evaluated against specific application requirements.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) mechanical features—SFM-125-02-S-D-A-P includes board guide and pick-and-place features while 5-104652-5 includes board lock; (2) available stacking heights—SFM-125-02-S-D-A-P offers five options versus three for 5-104652-5; (3) operating temperature range—SFM-125-02-S-D-A-P rated to 125°C maximum versus 105°C for 5-104652-5; (4) electrical specifications—SFM-125-02-S-D-A-P specifies 3.2A per contact and 250VAC while 5-104652-5 specifications are not provided.

Q: Are both connectors RoHS compliant?

A: Yes, both the SFM-125-02-S-D-A-P and 5-104652-5 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the pitch specification for these connectors?

A: Both connectors feature 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing in a 2-row configuration, resulting in 50 total positions.

Q: Do these connectors use the same contact finish?

A: Yes, both connectors feature gold-plated mating contacts with 30.0µin (0.76µm) contact finish thickness on the mating surface.

Q: What mounting method do these connectors use?

A: Both connectors are surface mount with solder termination and push-pull fastening type.
