Substitute Part Grouping Explanation

The SFM-115-03-S-D-A qualifies as a direct substitute for the SFM-115-L3-S-D-A based on the following critical parameters:

• Connector Type & Position Count: Both are 30-position receptacle connectors
• Pitch & Row Configuration: Identical 0.050" (1.27mm) mating pitch and 2-row layout with 0.050" row spacing
• Mounting & Termination: Both use through-hole mounting with solder termination
• Contact Specifications: Matching gold-plated mating contacts, beryllium copper material, and 3.2A per contact current rating
• Electrical Ratings: Both rated for 250VAC operation
• Temperature Range: Identical -55°C ~ 125°C operating temperature
• Compliance: Both ROHS3 compliant with UL94 V-0 flammability rating
• Fastening: Push-pull fastening mechanism on both models

The substitution is valid across all mated stacking heights (6.02mm through 11.63mm) supported by both connectors.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-115-L3-S-D-A and SFM-115-03-S-D-A are active production parts with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these two models should be based on:

• Inventory Availability: The SFM-115-L3-S-D-A has higher stock levels (1040 units) compared to SFM-115-03-S-D-A (672 units)
• Moisture Sensitivity: The SFM-115-03-S-D-A carries MSL 1 (Unlimited) rating, while the main part does not specify MSL classification
• Procurement Timeline: Either part is suitable for immediate deployment given current stock levels

All electrical, mechanical, and thermal specifications are identical, ensuring direct functional interchangeability in board-to-board and cable connector applications.

Frequently Asked Questions (FAQ)

Q: Can SFM-115-03-S-D-A be used as a direct replacement for SFM-115-L3-S-D-A?

A: Yes. Both connectors share identical specifications across all critical parameters including connector type, position count, pitch, mounting method, contact materials, electrical ratings, and operating temperature range. They are functionally interchangeable.

Q: Are there any differences in contact plating between these two models?

A: No. Both models feature gold-plated mating contacts with 30.0µin (0.76µm) thickness and tin-plated posts. Contact material is beryllium copper for both.

Q: Do both connectors support the same mated stacking heights?

A: Yes. Both SFM-115-L3-S-D-A and SFM-115-03-S-D-A support identical mated stacking heights: 6.02mm, 6.17mm, 7.80mm, 7.95mm, 9.58mm, 9.73mm, 11.48mm, and 11.63mm.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The SFM-115-03-S-D-A is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The SFM-115-L3-S-D-A does not specify an MSL classification. Both are suitable for standard storage and handling conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both the SFM-115-L3-S-D-A and SFM-115-03-S-D-A are ROHS3 compliant and carry EAR99 export classification.

Q: What is the current-carrying capacity per contact?

A: Both connectors are rated for 3.2A per contact at 250VAC maximum voltage.
