T7CS5D-24 Equivalent & Substitute Parts

Part Overview

The T7CS5D-24 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, configured as a Single Pole Double Throw (SPDT) contact form with a 24VDC coil. This through-hole mounted relay is rated for 12A continuous current and supports switching voltages up to 240VAC or 28VDC. The T7CS5D-24 is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across coil voltage, contact form, current rating, and termination style while meeting or exceeding the original specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T7CS5D-24 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Compatibility Criteria:

• Coil voltage: 24VDC (exact match required)
• Contact form: SPDT (1 Form C) (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Coil current: 15 mA (exact match required)
• Coil resistance: 1.6 kOhms (exact match required)
• Coil type: Non Latching (exact match required)
• Seal rating: Sealed - Fully (exact match required)
• Coil insulation: Class F (exact match required)

Secondary Compatibility Criteria (Equal or Superior):

• Contact rating (current): 12 A minimum
• Switching voltage: 240VAC / 28VDC minimum
• Operating temperature range: Must encompass or exceed -30°C ~ 85°C
• Must operate voltage: 18 VDC or lower
• Must release voltage: 1.2 VDC or lower
• Operate time: 10 ms or faster
• Release time: 5 ms or faster

Both substitute parts listed meet all primary compatibility criteria and maintain or exceed secondary performance parameters, confirming their suitability as direct replacements for the obsolete T7CS5D-24.

Engineering Selection Recommendations

J1071CS24VDC.36 Selection Criteria:

The J1071CS24VDC.36 is an active product manufactured by CIT Relay and Switch with ROHS3 compliance. This substitute provides a 15A contact rating, exceeding the 12A requirement of the T7CS5D-24. The switching voltage capability is reduced to 125VAC and 30VDC compared to the original specification. The must release voltage is elevated to 2.4VDC, and release time extends to 10ms. Operating temperature range expands to -40°C ~ 125°C. This part is suitable for applications where the reduced switching voltage and extended release time are acceptable within system design constraints.

J107F1CS1224VDC.36 Selection Criteria:

The J107F1CS1224VDC.36 is an active product manufactured by CIT Relay and Switch with RoHS compliance. This substitute maintains the exact 12A contact rating of the original part and provides superior switching voltage capability at 380VAC and 110VDC. The must release voltage is elevated to 2.4VDC, matching the J1071CS24VDC.36. Release time remains at 5ms, identical to the original specification. Operating temperature range expands to -55°C ~ 125°C. This part provides the closest functional alignment to the T7CS5D-24 across switching voltage and timing parameters.

Both substitute parts are active products with current manufacturing status and regulatory compliance certifications, ensuring long-term availability and supply chain stability compared to the obsolete T7CS5D-24.

Frequently Asked Questions (FAQ)

Q: Can the J1071CS24VDC.36 be used as a direct replacement for the T7CS5D-24?

A: The J1071CS24VDC.36 meets all primary compatibility criteria including 24VDC coil voltage, SPDT contact form, through-hole mounting, and PC pin termination. However, the switching voltage is reduced to 125VAC and 30VDC, and the release time extends to 10ms. These differences must be evaluated against application requirements before substitution.

Q: Can the J107F1CS1224VDC.36 be used as a direct replacement for the T7CS5D-24?

A: The J107F1CS1224VDC.36 meets all primary compatibility criteria and maintains the 12A contact rating and 5ms release time of the original part. The switching voltage capability is superior at 380VAC and 110VDC. The must release voltage is elevated to 2.4VDC. This part provides the closest functional alignment to the T7CS5D-24.

Q: What is the difference in contact material between the original and substitute parts?

A: The T7CS5D-24 uses Silver Cadmium Oxide (AgCdO) contact material, while both substitute parts use Silver Tin Oxide (AgSnO). Both materials are suitable for general purpose relay applications with sealed construction.

Q: Are the substitute parts available in different packaging options?

A: Yes. The J1071CS24VDC.36 is supplied in Box packaging, while the J107F1CS1224VDC.36 is supplied in Tube packaging. Packaging selection should align with production and inventory management requirements.

Q: What is the significance of the RoHS and REACH compliance status?

A: Both substitute parts are REACH Unaffected and carry RoHS compliance certifications (ROHS3 for J1071CS24VDC.36 and RoHS for J107F1CS1224VDC.36). This ensures compliance with environmental and hazardous substance regulations applicable to electronic components in regulated markets.

Q: How do the operating temperature ranges compare?

A: The T7CS5D-24 operates from -30°C to 85°C. The J1071CS24VDC.36 extends this to -40°C to 125°C, and the J107F1CS1224VDC.36 further extends to -55°C to 125°C. Both substitutes provide expanded temperature capability suitable for wider environmental applications.

Q: What is the impact of the elevated must release voltage in the substitute parts?

A: The T7CS5D-24 has a must release voltage of 1.2VDC, while both substitutes specify 2.4VDC. This parameter defines the maximum coil voltage at which the relay is guaranteed to release. The elevated specification in substitute parts requires verification that system design accommodates this higher threshold.
