Key Parameters

Substitute Part Grouping Explanation

Substitution of the HSC-A2-D1 is determined by strict equivalence across the following critical parameters:

• Connector type: SC receptacle to SC receptacle coupler configuration
• Simplex operation: Single fiber channel
• Mounting interface: Panel mount with flange and snap-in mechanism
• Housing and ferrule materials: Zinc alloy housing with zirconia ferrule
• Operating temperature range: -25°C to 70°C
• Moisture sensitivity classification: MSL 1

The HSC-A2-D1(01) maintains identical electrical and mechanical specifications across all these parameters, establishing it as a direct functional equivalent. Differences in packaging format (tray versus standard packaging) and product status do not affect connector performance or interchangeability in the application.

Parameter Comparison

Engineering Selection Recommendations

The HSC-A2-D1(01) is the manufacturer-designated substitute for the obsolete HSC-A2-D1. Both components share identical functional specifications and are mechanically and electrically interchangeable. The HSC-A2-D1(01) carries Last Time Buy status and includes RoHS compliance certification, making it the appropriate selection for new designs and ongoing system support. The transition from HSC-A2-D1 to HSC-A2-D1(01) involves no performance trade-offs or application limitations.

Frequently Asked Questions (FAQ)

Q: Can HSC-A2-D1(01) be used as a direct replacement for HSC-A2-D1?

A: Yes. Both parts are SC receptacle to SC receptacle simplex couplers with identical mounting, housing, ferrule materials, and operating temperature specifications. They are functionally equivalent and mechanically interchangeable.

Q: What is the difference between HSC-A2-D1 and HSC-A2-D1(01)?

A: The primary differences are product status and packaging. HSC-A2-D1 is obsolete with standard packaging, while HSC-A2-D1(01) is Last Time Buy status with tray packaging and includes RoHS compliance certification. Electrical and mechanical performance are identical.

Q: Does the color difference between the parts affect compatibility?

A: No. Color is a cosmetic attribute and does not affect connector function, performance, or interchangeability in SC receptacle to SC receptacle applications.

Q: Are there any temperature or environmental limitations when substituting these parts?

A: Both parts operate within the same temperature range (-25°C to 70°C) and share identical MSL classification (1 - Unlimited). No environmental limitations are introduced by substitution.

Q: What does Last Time Buy status mean for HSC-A2-D1(01)?

A: Last Time Buy indicates this is the final production run before the part is discontinued. Existing inventory should be evaluated for long-term system requirements, but the part remains fully functional and available for current procurement.
