ZHR-4-K Equivalent & Substitute Parts
Part Overview
The ZHR-4-K is a 4-position rectangular connector housing manufactured by JST Sales America Inc. as part of the ZH series. This receptacle housing is designed for crimp-terminated female socket contacts with a 1.50mm pitch and operates across a temperature range of -25°C to 85°C. The part is RoHS compliant and carries an MSL rating of 1 (Unlimited). As an active product with 1098 units in stock, the ZHR-4-K serves as a primary connector solution for applications requiring compact, reliable interconnection. Substitute parts are identified to provide design flexibility, supply chain alternatives, and compatibility options for equivalent applications.

Substitute Part Grouping Explanation
Substitute parts for the ZHR-4-K are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:
- Connector Type & Contact Configuration: Receptacle housing with female socket contacts
- Position Count & Pitch: 4-position arrangement at 0.059" (1.50mm) pitch
- Mounting & Termination: Free hanging (in-line) mounting with crimp termination
- Material & Environmental Compliance: Polyamide (PA66) insulation material, RoHS compliance, and MSL 1 rating
The substitute part 353908-4 (TE Connectivity AMP Connectors, Mini CT series) meets all critical substitution parameters. Both parts share identical electrical and mechanical specifications for connector type, position count, pitch, mounting configuration, and termination method. Both are manufactured from PA66 nylon insulation material and carry RoHS compliance with MSL 1 ratings, ensuring functional interchangeability in equivalent applications.

Engineering Selection Recommendations
Both the ZHR-4-K and 353908-4 are active products with RoHS compliance and MSL 1 ratings, making them suitable for equivalent applications. The ZHR-4-K (JST Sales America Inc.) is available with 1098 units in stock, while the 353908-4 (TE Connectivity AMP Connectors) has 2938 units in stock, providing supply chain flexibility.
The 353908-4 offers an extended operating temperature range of -30°C to 105°C compared to the ZHR-4-K range of -25°C to 85°C. This extended range may be advantageous for applications requiring operation at elevated or reduced temperatures beyond the ZHR-4-K specification. However, both parts maintain identical electrical and mechanical parameters for standard operating conditions.
Selection between these parts should be based on application temperature requirements, supply availability, and design specifications. Both parts are RoHS compliant and carry equivalent environmental ratings.
Frequently Asked Questions (FAQ)
Q: Can the 353908-4 directly replace the ZHR-4-K in existing designs?
A: Yes. Both parts are 4-position receptacle housings with female socket contacts at 0.059" (1.50mm) pitch, identical mounting configuration, and crimp termination. They share the same insulation material (PA66 nylon) and environmental compliance ratings (RoHS, MSL 1).
Q: What is the primary difference between these two parts?
A: The operating temperature range differs. The ZHR-4-K operates from -25°C to 85°C, while the 353908-4 operates from -30°C to 105°C. All other electrical and mechanical parameters are identical.
Q: Are contacts included with these housings?
A: No. Both the ZHR-4-K and 353908-4 are housings only. Contacts must be sourced separately and crimped into the housing.
Q: Do these parts require different contact types?
A: No. Both housings accept the same crimp-terminated female socket contacts designed for 0.059" (1.50mm) pitch applications.
Q: What is the significance of the MSL 1 rating?
A: MSL 1 (Unlimited) indicates these parts have unlimited shelf life and do not require moisture-controlled storage or baking procedures prior to assembly.
Q: Are both parts RoHS compliant?
A: Yes. Both the ZHR-4-K and 353908-4 are RoHS compliant, meeting environmental and regulatory requirements for restricted substance use.
