IL-S-12P-S2T2-EF Equivalent & Substitute Parts

Part Overview

The IL-S-12P-S2T2-EF is a rectangular connector header manufactured by JAE Electronics, designed for through-hole mounting with 12 vertical positions at 2.00mm pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The connector features shrouded 4-wall construction with kinked pin solder termination and detent lock fastening, suitable for board-to-cable/wire interconnections in industrial and general-purpose applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the IL-S-12P-S2T2-EF is determined by the following critical parameters that must align for functional compatibility:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 12
• Pitch - mating: 0.079" (2.00mm)
• Mounting type: Through Hole
• Termination: Kinked Pin, Solder
• Fastening type: Detent Lock
• Insulation material: Polyamide (PA66), Nylon 6/6
• Material flammability rating: UL94 V-0

Secondary Compatibility Factors:

• Operating temperature range
• Current and voltage ratings
• Contact shape and finish specifications
• Shrouding configuration

The two substitute parts identified—1-292161-2 (TE Connectivity) and SWR201-NRTN-S12-SA-WH (Sullins Connector Solutions)—meet the primary matching criteria. However, variations exist in secondary parameters that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

1-292161-2 (TE Connectivity AMP Connectors)

This substitute is an active product with established supply availability (43,479 pcs in stock). The part maintains core mechanical and electrical compatibility with the IL-S-12P-S2T2-EF, including identical pitch, position count, and termination method. The primary differences are shrouding configuration (3-wall versus 4-wall) and contact shape (circular versus square). The voltage rating of 125VAC is lower than the original specification of 300VAC/400VDC, and current rating varies by wire gauge rather than a fixed 3A per contact specification. Operating temperature range is not specified. This part is suitable for applications where the lower voltage and current ratings are acceptable and where the 3-wall shrouding provides sufficient EMI protection.

SWR201-NRTN-S12-SA-WH (Sullins Connector Solutions)

This substitute is an active product with moderate supply availability (643 pcs in stock). The part matches the IL-S-12P-S2T2-EF in shrouding configuration (4-wall), contact shape (square), and core mechanical specifications. The operating temperature range (-25°C to 85°C) is narrower than the original (-40°C to 85°C), and the current rating is limited to 1A per contact compared to the original 3A specification. Voltage rating is 125V, lower than the original 300VAC/400VDC specification. This part is suitable for applications with lower current and voltage requirements and operating temperatures above -25°C.

Compliance and Regulatory Status

Both substitute parts are ROHS3 compliant and maintain REACH Unaffected status, matching the regulatory profile of the original component. Both carry UL94 V-0 flammability ratings and unlimited moisture sensitivity levels (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can 1-292161-2 be used as a direct replacement for IL-S-12P-S2T2-EF?

A: 1-292161-2 is mechanically and functionally compatible for applications requiring 12-position, 2.00mm pitch through-hole header connectors with solder termination. However, the 3-wall shrouding differs from the original 4-wall configuration, and the voltage rating (125VAC) is significantly lower than the original specification (300VAC/400VDC). Compatibility depends on application voltage and current requirements.

Q: What is the key difference between the two substitute parts?

A: SWR201-NRTN-S12-SA-WH maintains the 4-wall shrouding and square contact shape of the original IL-S-12P-S2T2-EF, while 1-292161-2 uses 3-wall shrouding and circular contacts. Both have reduced voltage and current ratings compared to the original. SWR201-NRTN-S12-SA-WH has a narrower operating temperature range (-25°C to 85°C versus -40°C to 85°C).

Q: Are both substitute parts currently available?

A: Yes. 1-292161-2 has significantly higher inventory (43,479 pcs) compared to SWR201-NRTN-S12-SA-WH (643 pcs). Both are active products from established manufacturers.

Q: What are the critical parameters for substitution compatibility?

A: The following parameters must match for functional compatibility: 12 positions, 0.079" (2.00mm) pitch, through-hole mounting, kinked pin solder termination, detent lock fastening, and polyamide insulation material with UL94 V-0 rating. Variations in shrouding, contact shape, voltage rating, and current rating may be acceptable depending on specific application requirements.

Q: How do the voltage and current ratings compare?

A: The original IL-S-12P-S2T2-EF is rated for 300VAC/400VDC and 3A per contact. Both substitutes have lower ratings: 1-292161-2 is rated for 125VAC with current varying by wire gauge, and SWR201-NRTN-S12-SA-WH is rated for 125V with 1A per contact. Applications requiring the original voltage or current specifications cannot use these substitutes.

Q: What is the significance of shrouding configuration differences?

A: The original IL-S-12P-S2T2-EF and SWR201-NRTN-S12-SA-WH both feature 4-wall shrouding, which provides enhanced EMI shielding and mechanical protection. The 1-292161-2 uses 3-wall shrouding, which may be acceptable for applications with lower EMI requirements but provides less mechanical protection during mating/unmating cycles.
