SC-1628 Equivalent & Substitute Parts

Part Overview

The SC-1628 is a 28-position rectangular connector housing manufactured by Hirose Electric Co Ltd, part of the Sumicon 1600 series. This receptacle housing features female socket contacts, a blue resin insulation body, and flange-mounted design for free-hanging in-line applications. The part is classified as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC-1628 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Row Configuration: 28 positions arranged in 3 rows
• Mounting & Termination: Free hanging in-line mounting with crimp contact termination
• Physical Features: Flange design with resin insulation body
• Electrical & Environmental Compliance: MSL 1 rating, ECCN EAR99, HTSUS 8536.69.8000

The SC-1628(10) variant meets all these criteria. The primary difference is color (black versus blue) and product status (active versus obsolete), neither of which affects electrical or mechanical compatibility when the connector housing function is the determining factor.

Parameter Comparison

Engineering Selection Recommendations

The SC-1628(10) is the direct functional equivalent of the SC-1628. Selection between these parts should be based on the following criteria:

For New Designs or Restocking: SC-1628(10) is the appropriate choice. This part is active in production, carries RoHS compliance certification, and maintains full electrical and mechanical compatibility with the obsolete SC-1628. The black color variant does not affect connector performance or interchangeability.

For Legacy System Maintenance: SC-1628(10) provides a direct replacement path. The identical connector specifications ensure seamless integration into existing assemblies designed for the SC-1628.

Compliance Consideration: SC-1628(10) explicitly carries RoHS Compliant status, making it suitable for applications with regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can SC-1628(10) be used as a direct replacement for SC-1628?

A: Yes. Both parts are identical in all electrical and mechanical parameters: 28-position receptacle housing, female socket contacts, 3-row configuration, free hanging in-line mounting, crimp termination, flange design, and resin insulation. The color difference (black versus blue) does not affect functional compatibility.

Q: What is the significance of the color difference between SC-1628 and SC-1628(10)?

A: Color is a visual identifier only and does not impact electrical performance, mechanical fit, or contact compatibility. Selection between blue and black variants should be based on application-specific requirements such as visual identification, environmental marking standards, or assembly documentation.

Q: Why is SC-1628 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. SC-1628(10) represents the current production equivalent within the Sumicon 1600 series and should be specified for new designs and procurement.

Q: Does SC-1628(10) require different contact pins or mating connectors?

A: No. SC-1628(10) is a housing variant only. It accepts the same crimp contacts and mates with the same plug connectors as the SC-1628. Contacts are not included with either housing variant and must be sourced separately.

Q: What is the packaging difference between these parts?

A: SC-1628 packaging is not specified in available data. SC-1628(10) is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Is RoHS compliance a factor in substitution?

A: RoHS compliance is a regulatory consideration, not a functional compatibility factor. SC-1628(10) carries explicit RoHS Compliant certification, making it suitable for applications with environmental compliance mandates. The original SC-1628 RoHS status is not specified.
