Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSYJC1AC-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: 10A AC / 800mA DC
• Voltage rating: 120V AC / 115V DC
• Actuator type: Spring, Wire
• Mounting type: Chassis Mount
• Termination style: Cable Leads
• Ingress protection: IP67
• Operating force: 141gf
• Pretravel: 4.000" (102mm)
• RoHS compliance: Required
• MSL rating: 1 (Unlimited)

The LSJ1AC-7M meets all mandatory parameters and qualifies as a direct substitute. The primary distinction is product status: LSJ1AC-7M is active, whereas LSYJC1AC-7M is obsolete. Secondary differences in operating temperature range do not affect substitution eligibility within the specified parameter framework.

Engineering Selection Recommendations

LSJ1AC-7M as Primary Substitute:

The LSJ1AC-7M is the qualified substitute for the obsolete LSYJC1AC-7M. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and maintain identical electrical and mechanical specifications across all critical parameters.

Compliance Status:

Both parts carry RoHS Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for industrial and commercial applications. ECCN classification (EAR99) and HTSUS code (8536.50.7000) are identical, ensuring consistent export and tariff treatment.

Operational Considerations:

The LSJ1AC-7M features an extended operating temperature range (-12°C ~ 93°C) compared to the LSYJC1AC-7M (-12°C ~ 60°C). This extended range provides additional thermal margin for applications operating at elevated ambient temperatures, though both parts function within the specified range of the original design.

Availability:

LSJ1AC-7M inventory (1168 pcs) exceeds LSYJC1AC-7M inventory (979 pcs), supporting sustained procurement and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can LSJ1AC-7M directly replace LSYJC1AC-7M in existing applications?

A: Yes. Both components share identical circuit configuration (SPDT), current ratings (10A AC / 800mA DC), voltage ratings (120V AC / 115V DC), actuator type (Spring, Wire), mounting type (Chassis Mount), termination style (Cable Leads), and ingress protection (IP67). No circuit modifications or mechanical adaptations are required.

Q: What is the significance of the product status difference?

A: LSYJC1AC-7M is classified as obsolete, indicating discontinued manufacturing and limited future availability. LSJ1AC-7M is active, ensuring ongoing production, technical support, and supply chain access. Substitution to the active part is recommended for new designs and long-term system support.

Q: Does the extended operating temperature range of LSJ1AC-7M affect compatibility?

A: No. The extended range (-12°C ~ 93°C for LSJ1AC-7M versus -12°C ~ 60°C for LSYJC1AC-7M) represents an enhancement. Applications designed for the original temperature range operate within the substitute's specifications without performance degradation.

Q: Are there any packaging or lead configuration differences?

A: Both parts utilize identical termination style (Cable Leads) and mounting type (Chassis Mount). No packaging modifications are necessary for substitution.

Q: What compliance certifications apply to both parts?

A: Both LSYJC1AC-7M and LSJ1AC-7M are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification (EAR99) and HTSUS code (8536.50.7000) are identical, maintaining regulatory and tariff consistency.
