IL-G-3-2P-S3T2-SA Equivalent & Substitute Parts
Part Overview
The IL-G-3-2P-S3T2-SA is a rectangular connector header manufactured by JAE Electronics, designed for through-hole mounting in 2-position, 2.5mm pitch applications. This connector features male pin contacts with friction lock fastening and is rated for 3A per contact at operating temperatures from -40°C to 85°C.
The IL-G-3-2P-S3T2-SA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and maintenance requirements for systems utilizing this connector.

Substitute Part Grouping Explanation
Substitution eligibility for the IL-G-3-2P-S3T2-SA is determined by the following critical parameters:
- Connector type (Header)
- Contact type (Male Pin)
- Pitch - mating (0.098" / 2.5mm)
- Number of positions (2)
- Number of rows (1)
- Mounting type (Through Hole)
- Termination method (Solder)
- Fastening type (Friction Lock)
- Contact material (Brass)
- Insulation material (Polyamide PA66 / Nylon 6/6)
- Current rating (3A per contact)
- Material flammability rating (UL94 V-0)
- Moisture sensitivity level (1 - Unlimited)
The B2P-SHF-1AA manufactured by JST Sales America Inc. meets all critical substitution criteria. Both connectors share identical mating pitch, position count, row configuration, mounting method, termination type, fastening mechanism, contact and insulation materials, current rating, flammability rating, and moisture sensitivity classification.

Engineering Selection Recommendations
The B2P-SHF-1AA is a direct functional equivalent to the IL-G-3-2P-S3T2-SA for applications requiring a 2-position, 2.5mm pitch through-hole header connector with 3A current rating and UL94 V-0 flammability compliance.
The B2P-SHF-1AA offers the advantage of active product status with established supply chain availability (38,588 units in stock versus 686 units for the obsolete IL-G-3-2P-S3T2-SA). Both connectors carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.
The operating temperature range of the B2P-SHF-1AA (-25°C ~ 85°C) is narrower than the IL-G-3-2P-S3T2-SA (-40°C ~ 85°C). Applications requiring operation below -25°C must retain the original part or identify alternative solutions.
The B2P-SHF-1AA includes RoHS3 compliance certification, providing additional environmental regulatory alignment for new designs.
Frequently Asked Questions (FAQ)
Q: Can the B2P-SHF-1AA replace the IL-G-3-2P-S3T2-SA in existing designs?
A: Yes, for applications operating within the -25°C to 85°C temperature range. Both connectors share identical mating pitch (2.5mm), position count (2), row configuration (1), contact type (male pin), mounting method (through hole), termination (solder), fastening mechanism (friction lock), current rating (3A), and material specifications (brass contacts, PA66/Nylon 6/6 insulation, UL94 V-0 rated).
Q: What is the primary difference between these two connectors?
A: The IL-G-3-2P-S3T2-SA is obsolete with limited inventory, while the B2P-SHF-1AA is an active product with robust supply availability. The B2P-SHF-1AA has a narrower operating temperature minimum (-25°C versus -40°C) and includes RoHS3 compliance.
Q: Are there mechanical compatibility concerns with substitution?
A: Both connectors use identical 2.5mm mating pitch and friction lock fastening. The mated stacking heights differ (10mm for IL-G-3-2P-S3T2-SA versus 14.9mm for B2P-SHF-1AA). PCB layout and mating connector clearances must be verified to accommodate the increased stacking height of the substitute part.
Q: What packaging formats are available for the B2P-SHF-1AA?
A: The B2P-SHF-1AA is supplied in bulk packaging, compared to the original part's unspecified packaging format.
Q: Are both connectors RoHS compliant?
A: The B2P-SHF-1AA is RoHS3 compliant. RoHS status for the IL-G-3-2P-S3T2-SA is not specified in available documentation.
