Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D4B-3115N is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Current rating (10A AC minimum, 6A DC minimum)
• Voltage rating (120V AC minimum, 30V DC minimum)
• Actuator type (Side Rotary, Roller)
• Mounting type (Chassis Mount)
• Termination style (Screw Terminal)
• Ingress protection rating (IP67 minimum)

Secondary Compatibility Factors:

• Operating temperature range (must encompass -40°C to 80°C or be suitable for the application environment)
• Electrical and mechanical life ratings (must meet or exceed application cycle requirements)
• RoHS and regulatory compliance status

The D4B-2115N qualifies as a direct equivalent substitute, sharing identical electrical specifications, mechanical design, and environmental ratings while maintaining active product status. The GSAC07A1B from Honeywell represents a cross-manufacturer alternative with compatible mounting, termination, and ingress protection characteristics, though with different operational specifications that require application-level verification.

Parameter Comparison

Engineering Selection Recommendations

D4B-2115N (Omron): This part is the primary recommended substitute for the obsolete D4B-3115N. Both components are from the same D4B-N series and share identical electrical ratings, mechanical specifications, and environmental protection characteristics. The D4B-2115N maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. This substitution requires no design modifications and provides direct functional equivalence.

GSAC07A1B (Honeywell): This cross-manufacturer alternative shares compatible mounting, termination, and ingress protection specifications. However, the GSAC07A1B has significantly lower electrical life (25,000 cycles versus 500,000 cycles) and mechanical life (1,000,000 cycles versus 30,000,000 cycles) ratings. The operating temperature range is narrower (-25°C to 80°C versus -40°C to 80°C). This substitute is suitable only for applications where the reduced cycle life and narrower temperature range do not conflict with operational requirements. The GSAC07A1B is classified as active with RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the D4B-2115N directly replace the D4B-3115N without any modifications?

A: Yes. The D4B-2115N is a direct equivalent substitute. Both components share identical SPDT circuit configuration, 10A AC / 6A DC current ratings, 120V AC / 30V DC voltage ratings, side rotary roller actuator design, chassis mount configuration, screw terminal termination, IP67 ingress protection, and operating temperature range. No design or installation modifications are required.

Q: What are the key differences between the D4B-3115N and GSAC07A1B?

A: The primary differences are electrical and mechanical life ratings and operating temperature range. The D4B-3115N provides 500,000 electrical cycles and 30,000,000 mechanical cycles across -40°C to 80°C, while the GSAC07A1B provides 25,000 electrical cycles and 1,000,000 mechanical cycles across -25°C to 80°C. Both maintain IP67 ingress protection and chassis mount configuration with screw terminals.

Q: Is the GSAC07A1B suitable for high-cycle applications?

A: No. The GSAC07A1B is rated for 25,000 electrical cycles and 1,000,000 mechanical cycles, significantly lower than the D4B-3115N specification of 500,000 electrical cycles and 30,000,000 mechanical cycles. Applications requiring extended cycle life should use the D4B-2115N.

Q: What is the packaging difference between D4B-3115N and D4B-2115N?

A: The D4B-3115N is supplied in standard packaging, while the D4B-2115N is supplied in bulk packaging. This difference does not affect component functionality or electrical performance.

Q: Are both substitute parts RoHS compliant?

A: Yes. The D4B-2115N is ROHS3 compliant, and the GSAC07A1B is RoHS compliant. Both meet current environmental and regulatory requirements.

Q: Can the GSAC07A1B be used in applications requiring -40°C operation?

A: No. The GSAC07A1B operating temperature range is -25°C to 80°C. Applications requiring operation at -40°C must use the D4B-2115N, which is rated for -40°C to 80°C.
