Substitute Part Grouping Explanation

The ZMR-02 can be substituted with the Molex 5025780200 based on the following critical parameters that determine functional compatibility:

• Connector Type & Position Count: Both are 2-position plug housings
• Pitch Specification: Both maintain 0.059" (1.50mm) pitch, ensuring mechanical and electrical compatibility with mating connectors
• Row Configuration: Both feature single-row layouts
• Mounting Style: Both are free-hanging, in-line configurations
• Contact Termination: Both use crimp termination, allowing use of compatible contact sets
• Fastening Mechanism: ZMR-02 uses push-pull fastening; 5025780200 uses latch lock fastening—these are distinct mechanical interfaces and must be evaluated for application fit

The primary distinction lies in the fastening type and operating temperature range, which may influence selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ZMR-02 and 5025780200 are active products with current manufacturing status and full RoHS compliance certifications. Selection between these parts should be based on:

ZMR-02 (JST): Select when push-pull fastening is required by the application design and operating temperatures remain within -25°C to 85°C. This part is suitable for standard consumer and light industrial applications.

5025780200 (Molex CLIK-Mate 502578): Select when latch lock fastening is preferred for enhanced connection security, or when extended operating temperature range (-40°C to 105°C) is required. The PBT insulation material offers different mechanical properties compared to PA66 glass-filled nylon.

Both parts maintain identical pitch and position specifications, ensuring compatibility with the same contact sets and mating connectors within their respective fastening ecosystems.

Frequently Asked Questions (FAQ)

Q: Can the ZMR-02 and 5025780200 be used interchangeably in the same connector assembly?

A: No. While both are 2-position, 1.50mm pitch plug housings, they use different fastening mechanisms (push-pull versus latch lock). The mating receptacle must be designed for the specific fastening type. Direct substitution without receptacle compatibility verification will result in connection failure.

Q: What is the difference between push-pull and latch lock fastening?

A: Push-pull fastening uses a simple axial motion to connect and disconnect. Latch lock fastening uses mechanical latches that must be released before disconnection, providing higher retention force and resistance to accidental separation.

Q: Are the contact sets interchangeable between these two housings?

A: Both housings use crimp termination and 1.50mm pitch, but contact compatibility depends on the specific contact design and the housing's internal contact retention mechanism. Verify contact part numbers with the respective manufacturer before assuming interchangeability.

Q: What is the operating temperature significance between these parts?

A: The ZMR-02 operates from -25°C to 85°C, while the 5025780200 operates from -40°C to 105°C. Select the 5025780200 for applications requiring extended low-temperature performance or high-temperature environments beyond the ZMR-02 specification.

Q: Are both parts RoHS compliant?

A: Yes. The ZMR-02 is RoHS Compliant, and the 5025780200 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What packaging considerations apply to these parts?

A: The ZMR-02 is supplied in standard packaging (not specified), while the 5025780200 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
