Key Parameters

Substitute Part Grouping Explanation

Substitution of the PT22AS15B is based on strict electrical and mechanical parameter matching. The substitute part PT270615 maintains compatibility through the following critical parameters:

Electrical Compatibility:

• Identical coil voltage (115VAC)
• Identical contact form (DPDT / 2 Form C)
• Identical contact current rating (12A)
• Identical coil resistance (4.85 kOhms)
• Identical must operate voltage (92 VAC)
• Identical must release voltage (34.5 VAC)
• Identical contact material (Silver Nickel AgNi)

Mechanical Compatibility:

• Identical mounting type (Socketable)
• Compatible termination style (Plug In with additional Quick Connect option)
• Identical coil type (Non Latching)

The PT270615 represents an active product status alternative, ensuring ongoing availability and supply chain continuity while maintaining all critical electrical and mechanical specifications required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The PT270615 is the appropriate substitute for the obsolete PT22AS15B based on the following engineering criteria:

Product Status and Availability: The PT270615 maintains active product status with TE Connectivity Potter & Brumfield Relays, ensuring reliable procurement and supply chain continuity. The PT22AS15B is classified as obsolete, making the PT270615 the necessary alternative for new designs and system maintenance.

Regulatory Compliance: The PT270615 is ROHS3 compliant, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and identical ECCN classification (EAR99), ensuring consistent export and regulatory treatment.

Electrical and Mechanical Equivalence: All critical electrical parameters are identical between the two parts, including coil voltage, contact form, current rating, coil resistance, and operating/release voltage thresholds. Mechanical compatibility is maintained through identical socketable mounting and plug-in termination, with the PT270615 offering an additional Quick Connect termination option.

Operating Conditions: The PT270615 operating temperature range (-40°C to 70°C) covers the lower bound of the PT22AS15B range (-45°C to 70°C) with a 5°C difference at the minimum temperature. This variance is within acceptable engineering tolerance for general purpose relay applications.

Frequently Asked Questions (FAQ)

Q: Can the PT270615 directly replace the PT22AS15B in existing applications?

A: Yes. The PT270615 maintains identical electrical specifications including coil voltage (115VAC), contact form (DPDT), current rating (12A), coil resistance (4.85 kOhms), and operating/release voltage thresholds. Mechanical compatibility is confirmed through identical socketable mounting and plug-in termination.

Q: What is the difference in switching voltage between these parts?

A: The PT22AS15B has a maximum switching voltage of 440VAC, while the PT270615 is rated for 400VAC maximum. Both ratings are suitable for standard industrial control applications. System designers must verify that application switching voltages do not exceed 400VAC when using the PT270615.

Q: Are there differences in operating temperature ranges?

A: The PT22AS15B operates from -45°C to 70°C, while the PT270615 operates from -40°C to 70°C. The 5°C difference at the minimum temperature should be evaluated against specific application requirements. For applications requiring operation below -40°C, the PT22AS15B specifications must be maintained.

Q: What additional features does the PT270615 provide?

A: The PT270615 includes a mechanical indicator and test button, compared to the lighted indicator on the PT22AS15B. The PT270615 also offers an additional Quick Connect termination option (0.110" / 2.8mm) alongside the standard plug-in termination, providing installation flexibility.

Q: Is the PT270615 RoHS compliant?

A: Yes. The PT270615 is ROHS3 compliant, meeting current environmental regulations. The PT22AS15B RoHS status is not specified in available documentation.

Q: Are both parts from the same manufacturer?

A: Yes. Both the PT22AS15B and PT270615 are manufactured by TE Connectivity Potter & Brumfield Relays, ensuring consistent design standards and quality control.

Q: What is the coil current specification for the PT270615?

A: The coil current specification for the PT270615 is not provided in available technical documentation. The PT22AS15B specifies 8.8 mA coil current. For applications requiring precise coil current specifications, contact the manufacturer directly.
