JST 07HR-4K Equivalent & Substitute Parts

Part Overview

The JST 07HR-4K is a 7-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination, designed for discrete wire applications at 24 AWG. This connector features tin-lead contact finish and is classified as obsolete. Due to its obsolete status and RoHS non-compliance, identifying equivalent substitute parts is essential for ongoing design support, maintenance, and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JST 07HR-4K are identified based on the following critical parameters that determine functional compatibility:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 7 positions at 0.098" (2.50mm) pitch
• Row Configuration: Single row layout
• Cable Termination Method: IDC technology for discrete wire attachment
• Wire Gauge Compatibility: 24 AWG primary specification with acceptable range extension to 24-28 AWG
• Mounting Style: Free hanging in-line configuration
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity level)

The substitute parts identified maintain these core parameters while offering improvements in product status and regulatory compliance.

Engineering Selection Recommendations

TE Connectivity 177534-7 is the primary substitute for the JST 07HR-4K. This part maintains all critical electrical and mechanical parameters while offering active product status and RoHS compliance. The wire gauge specification extends to 24-28 AWG, providing compatibility with the original 24 AWG requirement. The black color matches the original connector, ensuring visual consistency in assembly.

TE Connectivity 2-177534-7 serves as an alternative substitute with identical electrical and mechanical specifications. This variant differs in housing color (natural instead of black) and carries "Not applicable" RoHS status rather than explicit compliance. Both TE parts are currently in active production with substantial inventory availability.

Selection between the two TE alternatives should be based on color requirements and RoHS compliance mandates specific to the application or regulatory environment.

Frequently Asked Questions (FAQ)

Q: Can TE 177534-7 directly replace the JST 07HR-4K in existing designs?

A: Yes. Both connectors share identical pitch (0.098" / 2.50mm), position count (7), row configuration (1), contact type (female socket), termination method (IDC), and mounting style (free hanging in-line). The wire gauge specification of 24-28 AWG on the TE part encompasses the original 24 AWG requirement.

Q: What is the difference between TE 177534-7 and TE 2-177534-7?

A: The primary difference is housing color: TE 177534-7 is black, matching the original JST connector, while TE 2-177534-7 is natural. RoHS compliance status also differs, with TE 177534-7 explicitly RoHS compliant and TE 2-177534-7 marked as not applicable.

Q: Does the contact finish change from tin-lead to tin affect compatibility?

A: The change from tin-lead to tin contact finish does not affect electrical or mechanical compatibility. Both finishes provide equivalent performance for IDC termination and mating operations within the specified environmental conditions.

Q: Are there any wire gauge limitations when substituting?

A: The TE substitute parts accept 24-28 AWG wire, which fully covers the original 24 AWG specification. Designs using 24 AWG wire will function identically with the substitute connectors.

Q: What is the inventory status of substitute parts?

A: TE 177534-7 has 712 pieces in stock, and TE 2-177534-7 has 914 pieces in stock, both listed as new original inventory.
