Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete OUAZ-SS-112D,900 is evaluated based on the following critical parameters:

Mandatory Compatibility Parameters:

• Coil voltage: 12VDC
• Mounting type: Through hole
• Termination style: PC pin
• Relay type: Telecom
• Coil type: Non-latching

Functional Parameters:

• Contact form configuration
• Contact current rating
• Switching voltage capability
• Coil resistance and current draw
• Operate and release timing characteristics

The IM06TS substitute part maintains compatibility with the 12VDC coil voltage requirement and through-hole PC pin mounting architecture. However, the IM06TS provides enhanced electrical performance characteristics including higher contact current rating (2A versus 1A), increased switching voltage capability (250VAC/220VDC versus 120VAC/24VDC), and improved operating temperature range (-40°C to 85°C versus -30°C to 60°C). The contact form differs from the original part (DPDT versus SPDT), which affects circuit integration requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The OUAZ-SS-112D,900 is obsolete and no longer manufactured. The IM06TS is an active product with current manufacturing support and documented availability (1633 pieces in stock).

Compliance and Certification: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring these certifications. Both components carry EAR99 ECCN classification and identical HTSUS codes (8536.41.0020).

Electrical Performance: The IM06TS provides superior electrical characteristics including lower coil current draw (11.6 mA versus 37.5 mA), higher contact current capacity (2A versus 1A), and enhanced switching voltage ratings (250VAC/220VDC versus 120VAC/24VDC). Faster switching times (3 ms operate and release versus 5 ms and 7 ms) are provided by the substitute.

Thermal Performance: The IM06TS supports an extended operating temperature range (-40°C to 85°C) compared to the original part (-30°C to 60°C), providing broader environmental compatibility.

Contact Form Difference: The IM06TS provides DPDT (2 Form C) configuration versus the SPDT (1 Form C) of the original part. Circuit redesign is required to accommodate the additional contact form. Applications requiring only single-pole switching must utilize only one of the two contact sets provided by the IM06TS.

Seal Rating: The IM06TS features hermetic sealing compared to the flux protection sealing of the original part, providing enhanced environmental protection in demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the IM06TS directly replace the OUAZ-SS-112D,900 without circuit modification?

A: Direct pin-for-pin replacement is not possible due to contact form differences. The OUAZ-SS-112D,900 provides one changeover contact (SPDT), while the IM06TS provides two changeover contacts (DPDT). Circuit redesign is required to accommodate the additional contact set. The through-hole PC pin mounting and 12VDC coil voltage are compatible.

Q: What are the coil current differences between these relays?

A: The OUAZ-SS-112D,900 draws 37.5 mA coil current, while the IM06TS draws 11.6 mA. The IM06TS requires significantly lower drive current due to its higher coil resistance (1.03 kOhms versus 320 Ohms). This difference affects driver circuit design and power consumption calculations.

Q: Are the switching voltage ratings compatible with existing applications?

A: The OUAZ-SS-112D,900 switches maximum 120VAC or 24VDC. The IM06TS switches maximum 250VAC or 220VDC. The IM06TS provides higher voltage capability and is suitable for applications within the original voltage specifications. Applications exceeding 120VAC or 24VDC require the IM06TS enhanced rating.

Q: What is the difference in operating temperature range?

A: The OUAZ-SS-112D,900 operates from -30°C to 60°C. The IM06TS operates from -40°C to 85°C. The IM06TS provides 10°C lower minimum temperature and 25°C higher maximum temperature capability, supporting broader environmental deployment.

Q: How do the seal ratings differ?

A: The OUAZ-SS-112D,900 uses sealed flux protection construction. The IM06TS uses hermetic sealing. Hermetic sealing provides complete environmental isolation and is suitable for applications requiring maximum protection against moisture and contaminants.

Q: What is the impact of different operate and release times?

A: The OUAZ-SS-112D,900 operates in 5 ms and releases in 7 ms. The IM06TS operates in 3 ms and releases in 3 ms. The IM06TS provides faster switching response and symmetrical timing characteristics. Applications with timing-critical requirements must account for these differences.

Q: Are both components RoHS compliant?

A: Both the OUAZ-SS-112D,900 and IM06TS are ROHS3 compliant and REACH unaffected. Both components meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What packaging is provided for the IM06TS?

A: The IM06TS is supplied in tube packaging. The original OUAZ-SS-112D,900 packaging specification is not provided in the available documentation. Packaging differences do not affect functional compatibility but may impact receiving, storage, and handling procedures.
