Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91MCE2-S1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

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

Mechanical Compatibility Requirements:

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

Environmental & Compliance Requirements:

• Operating temperature range must encompass -25°C to 85°C
• Electrical and mechanical life ratings must meet or exceed specified values
• RoHS compliance status must be maintained
• MSL rating must be 1 (Unlimited)

The NGCMA10AX01C meets all mandatory substitution criteria and is classified as an active product, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The NGCMA10AX01C is the qualified substitute for the obsolete 91MCE2-S1 based on the following engineering criteria:

Electrical Equivalence: Both components share identical circuit configuration (DPST-NO/NC), switch function (On-Mom, Off-Mom), current ratings (6A AC / 550mA DC), and voltage ratings (120V AC / 125V DC). Electrical performance is fully equivalent.

Mechanical Equivalence: Both components feature roller plunger actuation, chassis mount configuration, cable lead termination, and IP67 ingress protection. Mechanical interface compatibility is confirmed.

Compliance & Certification: Both components maintain RoHS compliance and MSL rating 1 (Unlimited). The substitute carries REACH Unaffected status, providing additional regulatory assurance.

Product Status Advantage: The NGCMA10AX01C is classified as active, ensuring continued availability, technical support, and supply chain stability compared to the obsolete 91MCE2-S1.

Temperature Range Consideration: The NGCMA10AX01C operates across -25°C to 75°C, which is 10°C narrower than the 91MCE2-S1 (-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 NGCMA10AX01C directly replace the 91MCE2-S1 in existing designs?

A: Yes, the NGCMA10AX01C provides direct electrical and mechanical substitution. Both components share identical circuit configuration, current/voltage ratings, actuator type, mounting method, and termination style. The primary design consideration is the operating temperature range, which is 10°C narrower on the substitute part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (91MCE2-S1 is obsolete; NGCMA10AX01C is active), operating temperature range (91MCE2-S1: -25°C to 85°C; NGCMA10AX01C: -25°C to 75°C), and operating force specifications (91MCE2-S1: 816gf; NGCMA10AX01C: 1122gf). All electrical and mechanical interface parameters are equivalent.

Q: Are there packaging differences between these parts?

A: The 91MCE2-S1 is supplied in standard packaging, while the NGCMA10AX01C is supplied in bulk packaging. This difference does not affect component functionality or electrical performance.

Q: What is the significance of the operating force difference?

A: The NGCMA10AX01C requires higher operating force (1122gf versus 816gf). This parameter is provided for reference but does not affect substitution eligibility, as both parts maintain the same switch function (On-Mom, Off-Mom) and circuit configuration.

Q: Is the NGCMA10AX01C suitable for applications requiring operation above 75°C?

A: The NGCMA10AX01C is rated for operation up to 75°C. Applications requiring operation between 75°C and 85°C must be evaluated against actual system thermal requirements. If sustained operation above 75°C is mandatory, alternative components outside this substitution group may be required.

Q: Are both parts RoHS compliant?

A: Yes, both the 91MCE2-S1 and NGCMA10AX01C are RoHS compliant. The NGCMA10AX01C additionally carries REACH Unaffected status.

Q: What is the cable length specification for the NGCMA10AX01C?

A: The cable length specification for the NGCMA10AX01C is not provided in the available technical data. The 91MCE2-S1 specifies a 1-meter cable length. Verification of cable length requirements is recommended during component procurement.
