Substitute Part Grouping Explanation
Substitution eligibility for the 04FFS-SP-TF is determined by the following critical parameters:
- Number of Positions: Must be 4
- Pitch (Contact Spacing): Must be 0.049" (1.25mm)
- Mounting Type: Must be Surface Mount, Right Angle
- Termination Method: Must be Solder
- Voltage Rating: Substitute must meet or exceed 50V
- Current Rating: Substitute must support 0.5A minimum per contact
- Operating Temperature Range: Substitute must cover or exceed -25°C ~ 85°C
- Material Flammability Rating: Must be UL94 V-0 or equivalent
- RoHS Compliance: Must be ROHS3 Compliant
The identified substitute FI-S4P-HFE from JAE Electronics meets these core electrical and mechanical requirements, enabling direct functional replacement in applications requiring 4-position, 1.25mm pitch surface mount connectors with solder termination.

Engineering Selection Recommendations
Both the 04FFS-SP-TF and FI-S4P-HFE are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings, meeting current regulatory requirements. The FI-S4P-HFE substitute provides enhanced electrical performance with 200V voltage rating and 1A current capacity per contact, exceeding the 04FFS-SP-TF specifications. The gold mating contact finish on the FI-S4P-HFE offers improved corrosion resistance compared to the tin finish of the primary part. Both connectors maintain MSL 1 (Unlimited) moisture sensitivity classification, suitable for standard storage and handling conditions. Selection between these parts should be based on specific application requirements, PCB layout constraints, and supplier availability.
Frequently Asked Questions (FAQ)
Q: Can the FI-S4P-HFE directly replace the 04FFS-SP-TF in existing designs?
A: Yes, the FI-S4P-HFE is functionally equivalent for applications requiring 4-position, 1.25mm pitch surface mount connectors with solder termination. Both parts share identical pitch, position count, mounting orientation, and termination method. Verify PCB footprint compatibility and connector body dimensions before implementation.
Q: What are the key differences between these two connectors?
A: The primary differences are contact finish material (tin vs. gold), connector type architecture (top/bottom contacts vs. receptacle with male pins), and electrical ratings. The FI-S4P-HFE provides higher voltage (200V vs. 50V) and current (1A vs. 0.5A) capacity. Operating temperature ranges differ slightly, with the FI-S4P-HFE rated to -40°C minimum versus -25°C for the 04FFS-SP-TF.
Q: Are both parts RoHS compliant?
A: Yes, both the 04FFS-SP-TF and FI-S4P-HFE are ROHS3 compliant with UL94 V-0 flammability ratings, meeting current environmental and safety standards.
Q: What is the packaging format for each part?
A: The 04FFS-SP-TF is supplied in Tape & Reel (TR) packaging. The FI-S4P-HFE is supplied in Strip packaging. Confirm packaging requirements for your procurement and assembly processes.
Q: How do the contact materials differ?
A: The 04FFS-SP-TF uses phosphor bronze contacts with tin finish. The FI-S4P-HFE uses copper alloy contacts with gold mating finish and tin-alloy post finish, providing enhanced corrosion resistance and contact reliability.
