Substitute Part Grouping Explanation

Substitute parts for the IL-S-8P-S2T2-EF are qualified based on the following critical parameters that determine functional compatibility:

Connector type (Header) and contact type (Male Pin)
Pitch specification (0.079" / 2.00mm)
Position count (8 positions, single row)
Shrouding configuration (Shrouded - 4 Wall)
Mounting method (Through Hole)
Fastening mechanism (Detent Lock)
Insulation material (Polyamide PA66/Nylon 6/6)
Material flammability rating (UL94 V-0)

The identified substitute parts B8B-PH-KL and SWR201-NRTN-S08-SA-WH meet these core mechanical and electrical compatibility criteria. Variations in current rating, voltage rating, operating temperature range, and contact material are noted but do not prevent functional substitution in applications within the specified parameter ranges of the substitute parts.

Engineering Selection Recommendations

B8B-PH-KL (JST Sales America Inc.) is an active product with RoHS compliance status. This substitute maintains mechanical compatibility with the IL-S-8P-S2T2-EF while offering reduced current rating (2A versus 3A per contact) and lower voltage rating (100V versus 300VAC/400VDC). The operating temperature range is narrower (-25°C to 85°C versus -40°C to 85°C). Selection of this part is appropriate for applications operating within its specified electrical and thermal parameters.

SWR201-NRTN-S08-SA-WH (Sullins Connector Solutions) is an active product with ROHS3 compliance status and higher inventory availability (14,522 pieces). This substitute maintains mechanical compatibility while specifying reduced current rating (1A per contact) and lower voltage rating (125V). The operating temperature range is also narrower (-25°C to 85°C). Selection of this part is appropriate for applications operating within its specified electrical and thermal parameters.

Both substitute parts are classified as active products, ensuring ongoing availability and support compared to the obsolete IL-S-8P-S2T2-EF.

Frequently Asked Questions (FAQ)

Q: Can B8B-PH-KL be used as a direct replacement for IL-S-8P-S2T2-EF?

A: B8B-PH-KL is mechanically compatible with IL-S-8P-S2T2-EF in terms of pitch, position count, shrouding, and mounting configuration. However, the current rating is reduced from 3A to 2A per contact, and voltage rating is reduced from 300VAC/400VDC to 100V. Substitution is valid only for applications operating within the B8B-PH-KL electrical specifications.

Q: Can SWR201-NRTN-S08-SA-WH be used as a direct replacement for IL-S-8P-S2T2-EF?

A: SWR201-NRTN-S08-SA-WH is mechanically compatible with IL-S-8P-S2T2-EF in terms of pitch, position count, shrouding, and mounting configuration. However, the current rating is reduced from 3A to 1A per contact, and voltage rating is reduced from 300VAC/400VDC to 125V. Substitution is valid only for applications operating within the SWR201-NRTN-S08-SA-WH electrical specifications.

Q: What are the key differences between the substitute parts?

A: Both B8B-PH-KL and SWR201-NRTN-S08-SA-WH share identical mechanical specifications. The primary differences are: B8B-PH-KL has higher current rating (2A versus 1A), higher voltage rating (100V versus 125V), and uses copper alloy contacts versus brass. SWR201-NRTN-S08-SA-WH offers significantly higher inventory availability.

Q: Are there temperature range limitations with the substitute parts?

A: Both substitute parts operate from -25°C to 85°C, compared to the IL-S-8P-S2T2-EF range of -40°C to 85°C. Applications requiring operation below -25°C are not compatible with either substitute part.

Q: Do the substitute parts have the same flammability rating?

A: Yes. Both B8B-PH-KL and SWR201-NRTN-S08-SA-WH maintain the UL94 V-0 material flammability rating of the original IL-S-8P-S2T2-EF.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts, including the IL-S-8P-S2T2-EF and both substitute parts, are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
