Substitute Part Grouping Explanation

Substitution eligibility for the JB5CS03AL00N is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: JB5
• Connector Type: Receptacle, Female Sockets
• Number of Positions: 3
• Shell Size - Insert: S
• Mounting Type: Panel Mount, Through Hole
• Mounting Feature: Bulkhead - Front Side Nut
• Termination: Solder
• Fastening Type: Push-Pull
• Shell Material: Copper Alloy
• Shell Finish: Chromium
• Contact Finish - Mating: Gold
• Ingress Protection: IP68
• Contact Material: Copper Alloy
• Contact Finish Thickness - Mating: 30.0µin (0.76µm)

Allowable Variation Parameters:

• Product Status: Active substitutes are preferred for obsolete parts
• Current Rating: Substitutes with equal or higher current capacity are acceptable
• Voltage Rating: Substitutes with equal or higher voltage rating are acceptable
• Operating Temperature: Substitutes with equal or wider temperature range are acceptable
• Packaging: Variation permitted based on procurement requirements

Two substitute parts meet these criteria and are identified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

JB5CS03AL00N-RK is the primary recommended substitute. This part maintains identical electrical and mechanical specifications to the main part, including the 3A current rating and -55°C ~ 85°C operating temperature range. The part is active in production status and RoHS compliant, providing regulatory alignment for new designs and procurement continuity. Inventory availability of 1136 units supports sustained supply.

JB5CS03AL00-RK is an alternative substitute with enhanced current capacity of 5A, suitable for applications where increased current headroom is beneficial. This part is active in production status. The operating temperature range is not specified in available documentation; applications requiring confirmed temperature performance should reference the main part specification. Inventory availability of 676 units is adequate for most procurement requirements.

Both substitutes are manufactured by JAE Electronics within the JB5 series and maintain full mechanical and electrical compatibility with the obsolete JB5CS03AL00N for panel-mount, solder-terminated applications.

Frequently Asked Questions (FAQ)

Q: Can JB5CS03AL00-RK be used as a direct replacement for JB5CS03AL00N?

A: JB5CS03AL00-RK is mechanically and electrically compatible. The primary difference is increased current rating (5A versus 3A). For applications operating at or below 3A, this substitute provides equivalent performance with enhanced capacity margin. Operating temperature specification is not provided for this variant; confirm temperature requirements with application specifications.

Q: What is the difference between JB5CS03AL00-RK and JB5CS03AL00N-RK?

A: Both parts are active substitutes for the obsolete JB5CS03AL00N. JB5CS03AL00N-RK maintains identical current rating (3A) and operating temperature range (-55°C ~ 85°C). JB5CS03AL00-RK provides higher current capacity (5A) but does not specify operating temperature. JB5CS03AL00N-RK includes RoHS compliance certification. Select based on current requirements and regulatory compliance needs.

Q: Are these substitutes suitable for medical and telecommunications applications?

A: Yes. All three parts are specified for medical, telecommunications, and test & measurement applications. Both substitute parts maintain the IP68 ingress protection rating, gold-plated contacts, and solder termination required for these environments.

Q: What is the impact of the packaging difference between these parts?

A: JB5CS03AL00N and JB5CS03AL00N-RK do not specify packaging format. JB5CS03AL00-RK is supplied in bulk packaging. Packaging variation does not affect electrical or mechanical performance; selection should be based on procurement and inventory management requirements.

Q: Can I use these substitutes interchangeably in existing designs?

A: Yes, for designs currently using JB5CS03AL00N. All substitute parts maintain identical mechanical mounting (panel mount, bulkhead, push-pull fastening) and electrical interface (3-position, solder termination, 320V rating). Verify current requirements do not exceed 3A for applications sensitive to current capacity specifications.
