Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the JB1HB03SL5 is determined by strict alignment with the following critical parameters:

• Series Compatibility: Base product number JB1HB03S ensures mechanical and electrical interface compatibility
• Position Count: 3-position configuration must be maintained
• Shell Size: B-3 insert size specification is non-negotiable for proper mating
• Connector Type & Function: Receptacle housing for female sockets
• Contact Specifications: Crimp contact type with size 22
• Mounting Configuration: Free-hanging (in-line) with threaded fastening and keyed orientation
• Environmental Rating: IP67 ingress protection and shielded design
• Compliance: RoHS compliance and MSL 1 rating

The substitute part JB1HB03SL5-RK shares the base product number JB1HB03S and maintains functional equivalence within the JB1 series architecture.

Engineering Selection Recommendations

The JB1HB03SL5-RK is the direct equivalent substitute for the obsolete JB1HB03SL5. Both components share identical base product architecture (JB1HB03S) and maintain equivalent functional specifications for 3-position circular connector receptacle housing applications.

Selection Basis:

• Product Status Transition: The substitute part carries active product status, ensuring continued manufacturer support and availability
• Compliance Alignment: Both parts maintain identical RoHS compliance and MSL 1 ratings, satisfying regulatory and environmental requirements
• Functional Equivalence: Shared base product number guarantees mechanical and electrical interface compatibility
• Supply Continuity: The active status of JB1HB03SL5-RK provides reliable sourcing for legacy system maintenance and new designs requiring this connector specification

Frequently Asked Questions (FAQ)

Q: What determines if JB1HB03SL5-RK is a valid substitute for JB1HB03SL5?

A: Both parts share the base product number JB1HB03S and are manufactured by JAE Electronics within the JB1 series. The substitute maintains the same functional description, connector type, and compliance certifications. The primary distinction is product status: the original is obsolete while the substitute is active.

Q: Are there mechanical compatibility concerns when substituting JB1HB03SL5-RK for JB1HB03SL5?

A: No. Both components are specified for identical mounting configurations (free-hanging, in-line with threaded fastening) and share the same shell size (B-3) and keyed orientation. Mechanical interfaces are fully compatible.

Q: Do both parts meet the same environmental and compliance requirements?

A: Yes. Both the JB1HB03SL5 and JB1HB03SL5-RK are RoHS compliant, carry MSL 1 rating, and share identical ECCN and HTSUS classifications. Environmental specifications remain consistent across both parts.

Q: Why is the original part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for the JB1HB03SL5. The JB1HB03SL5-RK represents the current active equivalent within the same product family, ensuring continued availability and manufacturer backing.

Q: Can inventory of both parts be used interchangeably in production?

A: Yes. The shared base product number and functional equivalence allow both parts to be used interchangeably in applications designed for the JB1HB03S specification. However, prioritize the active substitute (JB1HB03SL5-RK) for new designs and long-term supply security.
