Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HS21P-10(71) is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Plug, Female Sockets
• Number of Positions: 10
• Shell Size - Insert: 21
• Mounting Type: Free Hanging (In-Line)
• Termination: Solder Cup
• Fastening Type: Threaded
• Orientation: Keyed

Compatible Variation Parameters:

• Shell Material: Copper Alloy or Aluminum Alloy (both provide equivalent mechanical and electrical performance)
• Shell Finish: Nickel (standard for corrosion resistance)
• Contact Finish - Mating: Nickel or Silver (both acceptable for solder cup applications)
• Current Rating: Equal to or greater than 3A
• Voltage Rating: Equal to or greater than specified requirements

The JR21PK-10S(71) meets all mandatory matching parameters and provides enhanced electrical specifications, making it a valid substitute for the obsolete HS21P-10(71).

Parameter Comparison

Engineering Selection Recommendations

The JR21PK-10S(71) is the manufacturer-recommended substitute for the obsolete HS21P-10(71). Both connectors share identical mechanical interfaces and pin configurations, ensuring direct compatibility in existing designs.

The JR21PK-10S(71) provides enhanced electrical performance with a 10A current rating compared to the 3A rating of the HS21P-10(71), and includes specified voltage ratings of 250VAC and 350VDC. The substitute features RoHS compliance, addressing modern regulatory requirements. The aluminum alloy shell with nickel finish and silver contact finish provide equivalent corrosion resistance and electrical performance to the original copper alloy construction.

Both components maintain identical moisture sensitivity levels and export classifications, ensuring no changes to supply chain or regulatory documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can the JR21PK-10S(71) be used as a direct replacement for the HS21P-10(71)?

A: Yes. Both connectors share identical shell size (21), position count (10), mounting type (free hanging in-line), termination method (solder cup), fastening type (threaded), and keyed orientation. The mechanical interface is fully compatible.

Q: What are the differences between the two connectors?

A: The JR21PK-10S(71) features an aluminum alloy shell instead of copper alloy, silver contact finish instead of nickel, and includes additional features such as a backshell and coupling nut. The substitute provides higher current capacity (10A versus 3A) and specified voltage ratings (250VAC, 350VDC). The JR21PK-10S(71) is RoHS compliant, while the HS21P-10(71) status is not specified.

Q: Are there any packaging differences?

A: The HS21P-10(71) packaging information is not specified in the original documentation. The JR21PK-10S(71) is supplied in bulk packaging.

Q: What is the product status of the substitute?

A: The JR21PK-10S(71) is designated as Last Time Buy, indicating limited future availability. Procurement planning should account for this status.

Q: Do both connectors have the same moisture sensitivity level?

A: Yes. Both the HS21P-10(71) and JR21PK-10S(71) are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Are the export classifications identical?

A: Yes. Both connectors are classified as EAR99 and share the same HTSUS code (8536.69.4020), requiring no changes to export documentation or supply chain procedures.
