TSC-112L3,000 Equivalent & Substitute Parts

Part Overview

The TSC-112L3,000 is a telecom relay manufactured by TE Connectivity Potter & Brumfield Relays, classified as a Single Pole Double Throw (SPDT) relay with a 1 A contact rating and 12 VDC coil voltage. This component is designed for through-hole mounting applications requiring sealed, flux-protected operation in telecom environments.

The TSC-112L3,000 carries an Obsolete product status. Locating equivalent substitute parts is necessary for ongoing maintenance, repair, and legacy system support where original components are no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSC-112L3,000 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must match or remain within acceptable operating ranges:

Critical Matching Parameters:

• Coil Voltage: 12 VDC
• Contact Form: SPDT (1 Form C)
• Contact Rating: 1 A minimum
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Coil Resistance: 960 Ohms
• Coil Current: 12.5 mA
• Relay Type: Telecom

The HY1-12V from Panasonic Electric Works satisfies all critical electrical and mechanical parameters required for substitution. Both components share identical coil voltage, contact configuration, current rating, mounting method, and coil characteristics.

Parameter Comparison

Engineering Selection Recommendations

The HY1-12V is a direct functional equivalent to the TSC-112L3,000 for applications requiring a 12 VDC telecom relay with SPDT contact configuration and 1 A switching capacity.

Compliance Considerations:

Both components carry REACH Unaffected status and EAR99 ECCN classification. The HY1-12V includes RoHS3 compliance certification, whereas the TSC-112L3,000 compliance documentation does not specify RoHS status. For applications subject to RoHS requirements, the HY1-12V provides documented compliance assurance.

Product Status Impact:

The TSC-112L3,000 is classified as Obsolete, indicating discontinued manufacturing and limited availability. The HY1-12V carries a Not For New Designs status, indicating it remains available but is not recommended for new product development. For legacy system maintenance and repair applications, the HY1-12V represents the appropriate substitute choice.

Operating Parameter Differences:

The HY1-12V operates across a wider low-temperature range (-40°C versus -30°C minimum), providing enhanced performance in cold environments. The TSC-112L3,000 supports higher maximum switching voltage (120VAC, 30VDC versus 60VDC maximum), which may be relevant for specific high-voltage switching applications. Application requirements determine whether these differences impact suitability.

Frequently Asked Questions (FAQ)

Q: Can the HY1-12V directly replace the TSC-112L3,000 in existing circuit boards?

A: Yes. Both components share identical through-hole PC pin termination, coil voltage (12 VDC), contact configuration (SPDT), current rating (1 A), and coil resistance (960 Ohms). Physical footprint compatibility requires verification against the specific PCB layout, but electrical substitution is direct.

Q: What are the key differences between these two relays?

A: The primary differences are: (1) Switching voltage maximum—TSC-112L3,000 supports 120VAC/30VDC versus HY1-12V at 60VDC maximum; (2) Operating temperature range—HY1-12V extends to -40°C minimum versus -30°C for TSC-112L3,000; (3) Seal rating—TSC-112L3,000 provides flux protection while HY1-12V is fully sealed; (4) Contact material—TSC-112L3,000 uses Silver Nickel versus Silver/Gold in HY1-12V; (5) Must Release Voltage—TSC-112L3,000 at 0.6 VDC versus HY1-12V at 1.2 VDC.

Q: Which relay should be selected for new designs?

A: Neither component is recommended for new designs. The TSC-112L3,000 is Obsolete, and the HY1-12V carries Not For New Designs status. For new product development, consult current manufacturer catalogs for actively supported telecom relay alternatives meeting your specifications.

Q: Are there compliance or certification differences?

A: The HY1-12V includes RoHS3 compliance certification. The TSC-112L3,000 does not specify RoHS status in available documentation. Both components are REACH Unaffected and carry EAR99 ECCN classification. For applications requiring RoHS compliance, the HY1-12V provides documented certification.

Q: What packaging formats are available?

A: The TSC-112L3,000 is supplied in standard packaging. The HY1-12V is supplied in Tube packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: How do the release time specifications compare?

A: Both relays operate in 5 ms. The TSC-112L3,000 releases in 5 ms, while the HY1-12V releases in 4 ms. This 1 ms difference is negligible for most telecom applications but may be relevant in time-critical switching scenarios.
