IL-3P-S3FP2 Equivalent & Substitute Parts

Part Overview

The IL-3P-S3FP2 is a rectangular connector header manufactured by JAE Electronics, designed for through-hole, right-angle board-to-cable/wire applications. This 3-position connector operates at a 2.5mm pitch and features shrouded design with friction lock fastening. The part maintains active product status with 606 units in current inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across manufacturing locations. The DF1-3P-2.5DS(05) from Hirose Electric Co Ltd is identified as a functional equivalent based on matching core electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The DF1-3P-2.5DS(05) qualifies as a substitute based on alignment across the following critical parameters:

• Identical 3-position configuration at 2.5mm pitch
• Matching connector type (header) and contact type (male pin)
• Identical mounting method (through hole, right angle)
• Matching shrouding design (shrouded - 1 wall)
• Identical termination (solder) and fastening mechanism (friction lock)
• Equivalent contact material (brass) and finish (tin)
• Compatible insulation material (polyamide/nylon)
• Matching flammability rating (UL94 V-0)
• Identical RoHS compliance and MSL rating

Variations in contact length dimensions and operating temperature specifications do not prevent functional substitution in applications where the IL-3P-S3FP2 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The IL-3P-S3FP2 maintains active product status with adequate inventory availability. The DF1-3P-2.5DS(05) carries Last Time Buy status, indicating limited future availability from the manufacturer.

Both parts achieve RoHS compliance and UL94 V-0 flammability certification, meeting standard regulatory requirements for rectangular connector applications. Both maintain MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Selection between these parts should prioritize the IL-3P-S3FP2 for new designs and ongoing production due to its active status. The DF1-3P-2.5DS(05) serves as a qualified substitute for existing designs where inventory of the primary part becomes constrained, provided that the dimensional variations in contact length and insulation height do not conflict with PCB layout or mating interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF1-3P-2.5DS(05) be used as a direct replacement for the IL-3P-S3FP2 in existing assemblies?

A: Yes, the DF1-3P-2.5DS(05) is mechanically and electrically compatible for board-to-cable/wire applications. Both connectors share identical pitch, position count, mounting orientation, and contact configuration. Verify that PCB footprint tolerances accommodate the dimensional variations in contact length and insulation height before implementation.

Q: What is the significance of the Last Time Buy status on the DF1-3P-2.5DS(05)?

A: Last Time Buy status indicates that Hirose Electric Co Ltd will discontinue production of this part. Existing inventory may be available, but future procurement will not be possible. This status does not affect the part's technical performance or compliance certifications.

Q: Are there any compliance or certification differences between these two parts?

A: Both parts are RoHS compliant, carry UL94 V-0 flammability ratings, and share identical ECCN and HTSUS classifications. Compliance profiles are equivalent for regulatory purposes.

Q: How do the contact length differences affect connector performance?

A: Contact length variations reflect design differences between manufacturers but do not impact electrical performance or mating reliability when used with compatible cable connectors. Verify mating interface specifications to ensure contact engagement depth remains within acceptable ranges.

Q: What packaging considerations apply to these parts?

A: The IL-3P-S3FP2 packaging specification is not provided in available data. The DF1-3P-2.5DS(05) is supplied in bulk packaging. Confirm packaging requirements with your procurement specification before ordering.
