JC2AF-TM-DC24V-F Equivalent & Substitute Parts

Part Overview

The JC2AF-TM-DC24V-F is a general purpose relay manufactured by Panasonic Electric Works, configured as a DPST-NO (2 Form A) with a 24VDC coil and 10A contact rating. This chassis mount relay is designed for applications requiring reliable switching of AC loads up to 250VAC. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JC2AF-TM-DC24V-F is determined by the following critical parameters:

• Coil Voltage: 24VDC (must match exactly for direct control circuit compatibility)
• Contact Form: DPST-NO (2 Form A) (must match for switching topology)
• Mounting Type: Chassis Mount (must match for mechanical installation)
• Termination Style: Quick Connect configuration (must be compatible with existing wiring harness)
• Coil Type: Non Latching (must match for operational behavior)
• Contact Rating: Minimum 10A at 250VAC (must meet or exceed load requirements)

The T92P7D22-24 from TE Connectivity Potter & Brumfield Relays satisfies all critical substitution criteria. This relay maintains identical coil voltage, contact form, mounting type, and coil type. The substitute provides enhanced performance characteristics including higher contact current rating (30A vs 10A), improved switching voltage capability (277VAC vs 250VAC), and extended operating temperature range (-55°C to 85°C vs -50°C to 60°C). The termination style differs (0.250" vs 0.187"), requiring mechanical adapter consideration during installation.

Parameter Comparison

Engineering Selection Recommendations

The T92P7D22-24 is a functionally equivalent substitute for the obsolete JC2AF-TM-DC24V-F. Both relays share identical coil voltage (24VDC), contact form (DPST-NO), mounting configuration (Chassis Mount), and coil type (Non Latching), establishing direct functional compatibility.

The substitute provides superior performance margins across multiple parameters. The 30A contact rating exceeds the original 10A specification, providing increased load capacity. The 277VAC switching voltage rating surpasses the 250VAC maximum of the original part. The extended operating temperature range (-55°C to 85°C) accommodates broader environmental conditions compared to the original -50°C to 60°C range.

The T92P7D22-24 is currently in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The substitute is REACH Affected, whereas the original is REACH Unaffected; this distinction requires verification against specific application regulatory requirements.

Mechanical integration requires attention to termination style differences. The substitute uses 0.250" (6.3mm) Quick Connect terminals versus the original 0.187" (4.7mm) configuration. Wiring harness adaptation or terminal replacement may be necessary during installation.

Frequently Asked Questions (FAQ)

Q: Can the T92P7D22-24 directly replace the JC2AF-TM-DC24V-F without modifications?

A: The T92P7D22-24 provides functional equivalence for control circuit operation. However, the termination style differs (0.250" vs 0.187" Quick Connect), requiring mechanical adapter consideration or terminal replacement to integrate with existing wiring harnesses.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by coil voltage (24VDC), contact form (DPST-NO), mounting type (Chassis Mount), coil type (Non Latching), and contact current rating (minimum 10A). The T92P7D22-24 satisfies all these criteria.

Q: Does the higher coil current of the T92P7D22-24 (70.8 mA vs 41.6 mA) affect circuit design?

A: The substitute requires higher coil current, necessitating verification that the control circuit power supply and drive circuitry can supply the increased current demand without exceeding design limits.

Q: Are there compliance differences between the original and substitute?

A: The T92P7D22-24 is ROHS3 compliant and REACH Affected, whereas the JC2AF-TM-DC24V-F is REACH Unaffected. Application-specific regulatory requirements must be evaluated to confirm compliance acceptability.

Q: How do the switching speed differences impact application performance?

A: The T92P7D22-24 operates faster (15 ms vs 30 ms operate time), which may affect timing-sensitive applications. Release time is slightly longer (15 ms vs 10 ms). Application timing requirements must be evaluated against these specifications.

Q: What is the significance of the different contact materials?

A: The original uses Silver Tin Oxide (AgSnO) while the substitute uses Silver Cadmium Oxide (AgCdO). Both materials are suitable for general purpose switching applications at the specified voltage and current ratings.
