SDT-SH-112DM,000 Equivalent & Substitute Parts

Part Overview

The SDT-SH-112DM,000 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays. This component is a Single Pole Single Throw Normally Open (SPST-NO) relay with a 12VDC coil, rated for 10A switching capacity at 250VAC or 24VDC maximum. The relay features through-hole mounting with PC pin termination and is fully sealed for environmental protection.

The SDT-SH-112DM,000 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this relay configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDT-SH-112DM,000 is determined by strict equivalence across the following critical parameters:

Electrical Characteristics: Coil voltage (12VDC), contact form (SPST-NO), contact current rating (10A), switching voltage capability (250VAC, 24VDC maximum), coil current (44.4 mA), and coil resistance (267 Ohms) must remain identical.

Mechanical Characteristics: Mounting type (through hole), termination style (PC pin), and physical form factor must be preserved.

Performance Characteristics: Operating temperature range (-30°C ~ 60°C), operate time (15 ms), release time (8 ms), must operate voltage (9 VDC), and must release voltage (1.2 VDC) establish the functional envelope.

Material Specifications: Contact material composition (Silver Tin Oxide Indium Oxide) and seal rating (fully sealed) define the environmental and operational durability profile.

Substitute parts meeting all these parameters within the SDT and OEG series are classified as parametric equivalents and direct replacements.

Parameter Comparison

Engineering Selection Recommendations

The SDT-SH-112DM000 (without comma notation) is a parametric equivalent to the SDT-SH-112DM,000. All electrical, mechanical, and performance characteristics are identical across the critical parameters that define relay functionality and compatibility.

Product Status Consideration: The main part SDT-SH-112DM,000 is obsolete, while the substitute SDT-SH-112DM000 carries active product status. This distinction indicates ongoing availability and manufacturer support for the substitute part.

Compliance Differences: The main part is ROHS3 compliant. The substitute part is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this difference in compliance status.

Packaging: The substitute part is supplied in tube packaging, whereas the main part packaging is not specified. Tube packaging is standard for through-hole relay distribution and does not affect electrical or mechanical compatibility.

Supply Chain: Both parts are available in stock. The substitute part (1025 pcs) provides equivalent inventory availability to the main part (1019 pcs).

For applications where RoHS3 compliance is mandatory, the SDT-SH-112DM,000 must be retained or alternative compliant relay solutions must be evaluated. For applications without RoHS compliance requirements, the SDT-SH-112DM000 provides direct functional replacement with active product status and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the SDT-SH-112DM000 be used as a direct replacement for the SDT-SH-112DM,000?

A: Yes. The SDT-SH-112DM000 is a parametric equivalent. All electrical specifications (12VDC coil, 10A contact rating, 250VAC/24VDC switching voltage), mechanical characteristics (through-hole mounting, PC pin termination), and performance parameters (operate/release times, temperature range) are identical. The parts are functionally interchangeable.

Q: What is the difference between the part numbers SDT-SH-112DM,000 and SDT-SH-112DM000?

A: The difference is notation only. The comma in SDT-SH-112DM,000 is a formatting convention used in some documentation systems. The electrical and mechanical specifications are identical. Both parts belong to the same SDT series and OEG product line.

Q: Why is the main part marked as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued active production and support for the SDT-SH-112DM,000. The substitute part SDT-SH-112DM000 maintains active status, ensuring continued availability and manufacturer technical support.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance status is a regulatory and supply chain consideration, not an electrical or mechanical one. The SDT-SH-112DM,000 is ROHS3 compliant, while the SDT-SH-112DM000 is RoHS non-compliant. Applications subject to RoHS directives must retain the compliant part or identify alternative solutions. Applications without RoHS requirements are unaffected by this difference.

Q: What packaging is used for the substitute part?

A: The SDT-SH-112DM000 is supplied in tube packaging. Tube packaging is standard for through-hole relays and does not affect electrical compatibility or board-level installation procedures.

Q: Are the coil specifications identical between the two parts?

A: Yes. Both parts have identical coil specifications: 12VDC nominal voltage, 44.4 mA coil current, 267 Ohms coil resistance, 9 VDC must operate voltage, and 1.2 VDC must release voltage. Coil drive circuits require no modification.

Q: Do the contact ratings differ?

A: No. Both parts have identical contact ratings: 10A at 250VAC or 24VDC maximum switching voltage. Contact material composition (Silver Tin Oxide Indium Oxide) and seal rating (fully sealed) are also identical.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -30°C to 60°C. No thermal derating or environmental modifications are required when substituting between these parts.

Q: Are switching times identical?

A: Yes. Both parts have identical switching characteristics: 15 ms operate time and 8 ms release time. Circuit timing requirements remain unchanged with substitution.
