Substitute Part Grouping Explanation

Substitution eligibility for the LSJ1E-7M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT (DB/DM)
• Switch function: On-Momentary
• Current rating: 50mA (AC/DC)
• Voltage rating - AC: 250V
• Voltage rating - DC: 60V
• Actuator type: Spring, Wire
• Mounting type: Chassis Mount
• Termination style: Plug In
• Operating force: 141gf
• Pretravel: 4.000" (102mm)
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The LSYJB1E-7M qualifies as a direct substitute based on complete alignment with all mandatory parameters. The substitute part maintains identical electrical specifications, mechanical characteristics, and environmental compliance ratings while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The LSYJB1E-7M is a direct functional equivalent to the obsolete LSJ1E-7M. Both components share identical electrical and mechanical specifications, including circuit configuration, current and voltage ratings, actuator characteristics, and mounting parameters. The substitute part offers the advantage of active product status, ensuring continued availability and manufacturing support.

The LSYJB1E-7M provides an extended operating temperature range (-40°C ~ 121°C) compared to the main part (-12°C ~ 93°C), offering broader environmental compatibility without compromising any specified parameters. Both parts maintain RoHS compliance and identical moisture sensitivity classification.

Selection of the LSYJB1E-7M for replacement applications is supported by complete parameter equivalence and active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can the LSYJB1E-7M directly replace the LSJ1E-7M in existing applications?

A: Yes. The LSYJB1E-7M maintains identical electrical ratings (50mA at 250V AC / 60V DC), circuit configuration (SPDT), actuator type (spring, wire), mounting method (chassis mount), and mechanical characteristics (141gf operating force, 4.000" pretravel). All critical substitution parameters are equivalent.

Q: What is the primary difference between these two parts?

A: The LSJ1E-7M is classified as obsolete, while the LSYJB1E-7M maintains active product status. The substitute part also provides an extended operating temperature range (-40°C ~ 121°C versus -12°C ~ 93°C).

Q: Are there any compatibility concerns with the plug-in termination style?

A: No. Both parts utilize identical plug-in termination, ensuring mechanical and electrical compatibility with existing connector interfaces.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LSJ1E-7M and LSYJB1E-7M are RoHS compliant with identical moisture sensitivity level classification (MSL 1 - Unlimited) and ECCN designation (EAR99).

Q: Is the extended temperature range of the LSYJB1E-7M a limiting factor for applications designed for the LSJ1E-7M?

A: No. The extended range of the substitute part provides additional operational capability without introducing any restrictions for applications within the original temperature specification.
