Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2-1904011-2 are identified based on electrical and mechanical compatibility within the following critical parameters:

Electrical Compatibility Criteria:

• Coil voltage: 12VDC
• Contact form: SPST-NO (1 Form A)
• Operating temperature range: -40°C ~ 125°C
• Contact material: Silver or Silver Alloy
• Coil type: Non Latching

Mechanical Compatibility Criteria:

• Mounting configuration suitable for chassis or socketable applications
• Termination style compatible with Quick Connect standards
• Physical form factor allowing direct or adapter-based installation

Compliance Criteria:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)

Two substitute parts meet these criteria with varying degrees of parametric alignment:

1. 1-1904007-1 (Parametric Equivalent): Identical electrical specifications within the V23234 AXICOM series with active product status
2. 3-1393303-9 (MFR Recommended): Enhanced current rating (40A vs 30A) with different mounting approach (Socketable vs Chassis Mount) and active product status

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalent):

The 1-1904007-1 is the parametric equivalent substitute for the obsolete 2-1904011-2. Both parts share identical electrical specifications including coil voltage, contact rating, coil current, coil resistance, and operating voltage thresholds. Both are members of the V23234 AXICOM series with chassis mount configuration and Quick Connect termination. The 1-1904007-1 maintains active product status, ensuring long-term availability and supply chain continuity. This part is suitable for direct substitution in applications where the original 2-1904011-2 was specified.

For Enhanced Performance Applications:

The 3-1393303-9 is the manufacturer-recommended substitute offering increased contact current rating of 40A compared to the 30A rating of the main part. This part operates from the F4 series with socketable mounting configuration. The 3-1393303-9 exhibits lower coil current (133.3 mA vs 141.2 mA) and lower must-operate voltage (7.2 VDC vs 8 VDC), providing improved sensitivity. Switching voltage is rated at 14VDC nominal compared to 12VDC nominal for the main part. The socketable mounting requires adapter consideration for chassis mount applications. This part is suitable for applications requiring higher current capacity or improved coil sensitivity while maintaining SPST-NO contact form and 12VDC coil voltage.

Both substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 1-1904007-1 be used as a direct replacement for the 2-1904011-2?

A: Yes. The 1-1904007-1 is a parametric equivalent with identical coil voltage (12VDC), contact form (SPST-NO), contact rating (30A), coil current (141.2 mA), coil resistance (85 Ohms), operating voltage thresholds, and timing specifications. Both parts feature chassis mount configuration with Quick Connect termination. The 1-1904007-1 maintains active product status, making it the preferred direct replacement.

Q: What are the key differences between the 1-1904007-1 and 3-1393303-9?

A: The 1-1904007-1 maintains identical electrical and mechanical specifications to the main part within the V23234 AXICOM series. The 3-1393303-9 offers increased contact current rating (40A vs 30A), lower coil current (133.3 mA vs 141.2 mA), lower must-operate voltage (7.2 VDC vs 8 VDC), and socketable mounting instead of chassis mount. Both maintain 12VDC coil voltage, SPST-NO contact form, and identical timing characteristics.

Q: Is the 3-1393303-9 compatible with chassis mount applications?

A: The 3-1393303-9 features socketable mounting configuration, which differs from the chassis mount design of the main part. Integration into chassis mount applications requires mechanical adapter consideration or circuit board redesign to accommodate the socketable form factor.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. Both 1-1904007-1 and 3-1393303-9 are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the obsolete 2-1904011-2.

Q: What is the operating temperature range for all parts?

A: All three parts operate across the identical temperature range of -40°C to 125°C, ensuring thermal compatibility across applications.

Q: Are there differences in contact material between the substitute parts?

A: The 2-1904011-2 and 1-1904007-1 feature Silver (Ag) contact material. The 3-1393303-9 uses Silver Alloy contact material. Both materials are suitable for general purpose relay applications with equivalent switching characteristics.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring 30A contact rating and chassis mount configuration, the 1-1904007-1 is the appropriate selection due to its active product status and parametric equivalence. For applications requiring 40A contact rating or improved coil sensitivity, the 3-1393303-9 is suitable, provided socketable mounting is compatible with the application.
