IL-G-4P-S3L2-SA Equivalent & Substitute Parts

Part Overview

The IL-G-4P-S3L2-SA is a rectangular connector header manufactured by JAE Electronics, designed for through-hole, right-angle board-to-cable/wire applications. This 4-position connector operates at 3A per contact with a 2.5mm pitch and is rated for -40°C to 85°C operation. The part is currently in active production status with 4323 units in stock.

Substitute parts become necessary when the main part reaches end-of-life status, inventory constraints occur, or design flexibility is required across manufacturing locations. The DF1-4P-2.5DS(05) from Hirose Electric Co Ltd is identified as a functional equivalent based on matching electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL-G-4P-S3L2-SA is determined by the following critical parameters:

• Connector pitch: 0.098" (2.50mm) — must match exactly for mating compatibility
• Number of positions: 4 positions — determines signal/power routing capability
• Mounting configuration: Through hole, right angle — ensures PCB layout compatibility
• Contact type and material: Male pin, brass with tin finish — maintains electrical performance
• Current rating: 3A per contact minimum — supports power delivery requirements
• Shrouding style: Shrouded - 1 wall — provides mechanical alignment and polarization
• Termination method: Solder — compatible with standard PCB assembly processes
• Insulation material: Polyamide (PA) or Nylon — ensures thermal and chemical resistance
• Compliance certifications: UL94 V-0, ROHS3, MSL 1 — meets regulatory and environmental standards

The DF1-4P-2.5DS(05) meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The DF1-4P-2.5DS(05) is a qualified substitute for the IL-G-4P-S3L2-SA based on the following engineering criteria:

Electrical Compatibility: Both connectors maintain identical current ratings (3A per contact), contact material (brass with tin finish), and pitch specifications (2.50mm). Electrical performance is equivalent.

Mechanical Compatibility: Mounting configuration, shrouding style, and termination method are identical. PCB footprint compatibility is maintained. Contact length variations (mating: 4.50mm vs. 4.00mm; post: 3.00mm vs. 4.60mm) fall within acceptable mechanical tolerances for through-hole solder joint formation and mating depth.

Regulatory Compliance: Both parts meet UL94 V-0 flammability requirements, ROHS3 compliance, and MSL 1 moisture sensitivity ratings. REACH status is unaffected for both parts.

Operational Temperature: The DF1-4P-2.5DS(05) operates at -30°C to 85°C, compared to -40°C to 85°C for the IL-G-4P-S3L2-SA. This represents a 10°C reduction in minimum operating temperature. Selection should verify that application requirements do not mandate operation below -30°C.

Product Status Consideration: The IL-G-4P-S3L2-SA is in active production with 4323 units in stock. The DF1-4P-2.5DS(05) is designated Last Time Buy, indicating limited future availability. Substitution should be evaluated based on long-term supply requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF1-4P-2.5DS(05) be used as a direct replacement for the IL-G-4P-S3L2-SA in existing designs?

A: Yes, the DF1-4P-2.5DS(05) is mechanically and electrically compatible for board-to-cable/wire applications. The 4-position, 2.50mm pitch configuration, through-hole right-angle mounting, and 3A current rating are identical. Contact length variations are within acceptable tolerances for standard PCB assembly. Verify that your application does not require operation below -30°C, as the Hirose part has a higher minimum operating temperature limit.

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

A: The primary differences are: (1) Contact length specifications vary slightly (mating and post lengths differ by 0.5mm and 0.38mm respectively); (2) Operating temperature minimum is -30°C for the DF1-4P-2.5DS(05) versus -40°C for the IL-G-4P-S3L2-SA; (3) Product status differs, with the JAE part in active production and the Hirose part designated Last Time Buy. All other electrical, mechanical, and compliance parameters are equivalent.

Q: Are there any PCB layout modifications required when switching from IL-G-4P-S3L2-SA to DF1-4P-2.5DS(05)?

A: No PCB layout modifications are required. Both connectors share identical pitch (2.50mm), number of positions (4), mounting type (through-hole right angle), and shrouding configuration. The footprint and mounting hole pattern are compatible. Solder joint formation may vary slightly due to contact length differences, but standard reflow profiles remain applicable.

Q: Which connector should be selected for new designs?

A: For new designs, the IL-G-4P-S3L2-SA is recommended due to active production status and extended availability. The DF1-4P-2.5DS(05) should be considered only when the JAE part is unavailable or when design flexibility across multiple suppliers is required. Verify long-term supply commitments before finalizing component selection.

Q: Are both connectors RoHS and REACH compliant?

A: Yes, both the IL-G-4P-S3L2-SA and DF1-4P-2.5DS(05) are ROHS3 compliant and REACH unaffected. Both meet UL94 V-0 flammability requirements and carry MSL 1 (unlimited) moisture sensitivity ratings, making them suitable for standard manufacturing and storage environments.
