The AT04-08PA-SR2BK currently maintains higher inventory levels (1318 units) compared to the AT04-08PA-SRBK (754 units), which may influence sourcing decisions based on lead time and availability requirements.

Frequently Asked Questions (FAQ)

Q: Are AT04-08PA-SRBK and AT04-08PA-SR2BK functionally interchangeable?

A: Yes. Both parts are parametric equivalents with identical specifications across connector type, position count, mounting configuration, termination method, fastening mechanism, operating temperature range, and feature set. They are interchangeable in applications requiring 8-position rectangular connector receptacle housings within the ATSeries™ family.

Q: What is the difference between these two part numbers?

A: The part numbers differ only in their suffix designation (SRBK versus SR2BK). All electrical and mechanical parameters are identical. The difference reflects internal Amphenol Sine Systems Corp product line organization and does not affect functional performance or compatibility.

Q: Can I use AT04-08PA-SR2BK as a direct replacement for AT04-08PA-SRBK?

A: Yes. The AT04-08PA-SR2BK is a direct substitute with no design or performance differences. It maintains the same connector type, position configuration, mounting method, and operating specifications.

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

A: No. Both parts carry identical RoHS3 compliance status and REACH Unaffected designation. Both are classified under ECCN EAR99 and HTSUS code 8538.90.6000.

Q: What is the operating temperature range for both parts?

A: Both AT04-08PA-SRBK and AT04-08PA-SR2BK operate across the temperature range of -55°C to 125°C.

Q: Do these parts include contacts?

A: No. Both part numbers specify that contacts are not included. Contacts must be sourced separately and crimped into the housing according to Amphenol Sine Systems Corp specifications.

Q: What mounting configuration do these connectors support?

A: Both parts are configured for Free Hanging (In-Line) mounting, suitable for applications requiring flexible cable-mounted connector assemblies.

Q: Are these parts sealed?
