Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91MCE2-P2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be DPST-NO/NC
• Current rating must support minimum 6A AC and 550mA DC
• Voltage rating must support minimum 120V AC and 125V DC
• Switch function must be On-Mom, Off-Mom

Mechanical Equivalence Requirements:

• Actuator type must be roller plunger
• Mounting type must be chassis mount
• Termination style must be cable leads
• Ingress protection must be IP67 or higher

Environmental & Compliance Requirements:

• Operating temperature range must encompass the original specification or be compatible with application requirements
• RoHS compliance status must be maintained
• Electrical and mechanical life ratings must meet or exceed original specifications

The NGCMA20AX01C meets all electrical and mechanical equivalence criteria and is classified as an active product, making it a direct functional substitute for the obsolete 91MCE2-P2.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA20AX01C is the qualified substitute for the obsolete 91MCE2-P2 based on the following engineering criteria:

Electrical Compatibility: Both components share identical circuit configuration (DPST-NO/NC), current ratings (6A AC / 550mA DC), and voltage ratings (120V AC / 125V DC). Switching function and electrical life specifications are identical.

Mechanical Compatibility: Both components feature identical actuator type (roller plunger), mounting configuration (chassis mount), termination style (cable leads), and ingress protection rating (IP67). Mechanical life ratings are equivalent at 5,000,000 cycles.

Regulatory Compliance: Both components maintain RoHS compliance and are manufactured by the same supplier, ensuring consistency in manufacturing standards and quality control.

Product Status Advantage: The NGCMA20AX01C is classified as an active product with current inventory availability (886 pieces), whereas the 91MCE2-P2 is obsolete. Selection of the NGCMA20AX01C ensures long-term supply chain continuity and access to technical support.

Temperature Range Consideration: The NGCMA20AX01C operates across -25°C to 75°C, which is narrower than the original 91MCE2-P2 specification of -25°C to 85°C. Applications requiring operation above 75°C must be evaluated against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can the NGCMA20AX01C directly replace the 91MCE2-P2 in existing installations?

A: Yes, the NGCMA20AX01C is electrically and mechanically equivalent to the 91MCE2-P2 across all critical parameters including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and ingress protection. Both components feature identical cable lead termination and IP67 rating. Direct substitution is supported for applications operating within the NGCMA20AX01C temperature range of -25°C to 75°C.

Q: What is the difference in operating temperature range between these two parts?

A: The 91MCE2-P2 operates from -25°C to 85°C, while the NGCMA20AX01C operates from -25°C to 75°C. The substitute has a 10°C narrower upper temperature limit. Applications requiring operation above 75°C must verify compatibility with the NGCMA20AX01C specifications before implementation.

Q: Are there packaging differences between the 91MCE2-P2 and NGCMA20AX01C?

A: The 91MCE2-P2 packaging information is not specified in the provided data. The NGCMA20AX01C is supplied in bulk packaging. Packaging configuration should be verified against procurement requirements for your specific application.

Q: What is the cable length specification for the NGCMA20AX01C?

A: The cable length specification for the NGCMA20AX01C is not provided in the available technical data. The original 91MCE2-P2 features a 2-meter cable lead. Cable length requirements should be confirmed with the supplier or technical documentation for the NGCMA20AX01C.

Q: Are both components RoHS compliant?

A: Yes, both the 91MCE2-P2 and NGCMA20AX01C are RoHS compliant, ensuring compatibility with environmental and regulatory requirements for restricted substance use.

Q: Why is the 91MCE2-P2 listed as obsolete?

A: The 91MCE2-P2 is classified as obsolete, indicating that the manufacturer has discontinued production. The NGCMA20AX01C is the active equivalent product and is the recommended selection for new designs and ongoing system maintenance to ensure supply chain continuity.
