J115F11C24VDCS.6 Equivalent & Substitute Parts

Part Overview

The J115F11C24VDCS.6 is a general purpose relay manufactured by CIT Relay and Switch, designed for SPDT (Single Pole Double Throw) switching applications. This through-hole mounted relay operates on a 24VDC coil and is rated for 40A contact current at switching voltages up to 277VAC or 110VDC maximum. The relay features a sealed, fully enclosed design with Class F coil insulation and silver tin oxide contact material, suitable for industrial control and automation applications requiring reliable switching performance across extended temperature ranges from -55°C to 125°C.

The J115F11C24VDCS.6 maintains Active product status with full RoHS compliance and REACH unaffected classification. Substitute part identification becomes necessary when primary inventory is unavailable, when procurement lead times require alternative sourcing, or when design flexibility permits selection from equivalent variants within the same product series.

Substitute Part Grouping Explanation

Substitute parts for the J115F11C24VDCS.6 are identified within the J115F1 series based on strict electrical and mechanical parameter equivalence. All substitute candidates share identical specifications across the following critical parameters:

• Coil voltage: 24VDC
• Contact form: SPDT (1 Form C)
• Contact current rating: 40 A
• Switching voltage capability: 277VAC, 110VDC maximum
• Coil current: 25 mA
• Coil type: Non Latching
• Mounting configuration: Through Hole
• Termination style: PC Pin
• Operating temperature range: -55°C to 125°C
• Contact material composition: Silver Tin Oxide (AgSnO)
• Coil resistance: 960 Ohms
• Seal rating: Sealed - Fully
• Coil insulation class: Class F
• Regulatory compliance: RoHS Compliant, REACH Unaffected

Substitution is valid when all parameters listed above remain constant across part numbers. Variations in part number nomenclature (such as suffix designations) do not alter functional or electrical characteristics when parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—J115F11C24VDCS.6, J115F11C24VDCS6.6, and J115F11C24VDCSH.6—are functionally equivalent and maintain Active product status with identical regulatory compliance profiles. Each part is RoHS Compliant, REACH Unaffected, and carries MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special handling requirements during storage or assembly.

Selection among these equivalent parts should be based on inventory availability and procurement lead times. The J115F11C24VDCSH.6 currently maintains the highest inventory level at 1606 pieces, followed by J115F11C24VDCS6.6 at 1313 pieces, with J115F11C24VDCS.6 at 944 pieces. All parts are supplied in tube packaging and are suitable for direct substitution in applications requiring 24VDC SPDT general purpose relays with 40A contact ratings.

No performance differentiation exists between these parts based on provided specifications. Circuit design, PCB layout, and thermal management considerations remain unchanged regardless of which equivalent part number is selected.

Frequently Asked Questions (FAQ)

Q: Can J115F11C24VDCS6.6 be used as a direct replacement for J115F11C24VDCS.6?

A: Yes. Both parts share identical electrical specifications, contact ratings, coil characteristics, and operating parameters. The parts are mechanically and functionally interchangeable in all applications where J115F11C24VDCS.6 is specified.

Q: What is the difference between J115F11C24VDCSH.6 and J115F11C24VDCS.6?

A: No functional or electrical differences exist between these parts. All specified parameters—coil voltage, contact form, current rating, switching voltage, operating temperature range, and contact material—are identical. Differences in part number nomenclature do not reflect performance variations.

Q: Are all three substitute parts rated for the same switching voltage?

A: Yes. All three parts are rated for maximum switching voltages of 277VAC or 110VDC. Contact current rating remains 40A across all variants.

Q: Do these relays require special handling during assembly?

A: No. All three parts carry MSL Level 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard through-hole assembly procedures apply without special precautions.

Q: Can these relays operate reliably across the full -55°C to 125°C temperature range?

A: Yes. All three parts are specified for continuous operation across the -55°C to 125°C temperature range with identical must-operate and must-release voltage thresholds of 18VDC and 2.4VDC respectively.

Q: Are all substitute parts RoHS compliant?

A: Yes. J115F11C24VDCS.6, J115F11C24VDCS6.6, and J115F11C24VDCSH.6 are all RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the coil resistance specification for these relays?

A: All three parts have a coil resistance of 960 Ohms at 24VDC, with a coil current draw of 25 mA during operation.

Q: Can these relays be used in latching applications?

A: No. All three parts are specified as Non Latching coil type relays. They require continuous coil energization to maintain contact closure and will release when coil power is removed.
