HD1E-M-DC5V Equivalent & Substitute Parts

Part Overview

The HD1E-M-DC5V is a general purpose relay manufactured by Panasonic Electric Works, configured as a single pole double throw (SPDT) contact form with 1A contact rating and 5VDC coil voltage. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design considerations. The relay features through-hole mounting with PC pin termination, sealed construction, and operates across a temperature range of -25°C to 60°C.

Substitute Part Grouping Explanation

Substitution eligibility for the HD1E-M-DC5V is determined by strict alignment with the following core parameters: 5VDC coil voltage, SPDT contact configuration, 1A contact rating, through-hole mounting, PC pin termination, non-latching coil type, and fully sealed construction. Substitute parts must maintain these electrical and mechanical specifications to ensure functional compatibility within existing circuit designs.

The identified substitute parts are grouped as follows:

Direct Manufacturer Substitute: HY1-5V (Panasonic Electric Works) — same manufacturer, matching core electrical and mechanical parameters.

Similar Manufacturer Substitute: TSC-105D3H,000 (TE Connectivity Potter & Brumfield Relays) — alternative manufacturer with equivalent functional specifications and active product status.

Engineering Selection Recommendations

For Maintenance and Replacement: The HY1-5V serves as the direct manufacturer equivalent from Panasonic Electric Works. Both the HD1E-M-DC5V and HY1-5V share identical core electrical and mechanical specifications. The HY1-5V carries a "Not For New Designs" status, indicating it remains available for legacy system support.

For New Designs and Long-Term Availability: The TSC-105D3H,000 from TE Connectivity Potter & Brumfield Relays is classified as active product status, ensuring continued availability and supply chain stability. This part meets all functional substitution criteria and carries ROHS3 compliance certification. The TSC-105D3H,000 exhibits improved operating temperature range (-30°C to 80°C) and faster switching characteristics compared to the original HD1E-M-DC5V.

Compliance Considerations: Both substitute parts maintain REACH Unaffected or Vendor Undefined status and carry EAR99 ECCN classification, consistent with the original component. The TSC-105D3H,000 and HY1-5V both achieve ROHS3 compliance, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the HY1-5V directly replace the HD1E-M-DC5V in existing circuits?

A: Yes. The HY1-5V maintains identical coil voltage (5VDC), contact form (SPDT), contact rating (1A), mounting type (through-hole), and termination style (PC pin). Both components are non-latching, fully sealed relays with matching core electrical parameters.

Q: What are the key differences between the HD1E-M-DC5V and TSC-105D3H,000?

A: The TSC-105D3H,000 exhibits lower must-operate voltage (3.75VDC vs. 4VDC), faster switching times (5ms operate vs. 10ms), lower must-release voltage (0.25VDC vs. 0.5VDC), and an extended operating temperature range (-30°C to 80°C vs. -25°C to 60°C). Contact material differs: TSC-105D3H,000 uses silver nickel (AgNi) versus the silver/gold (Ag/Au) composition of the original. Coil resistance and current specifications also vary.

Q: Is the TSC-105D3H,000 suitable for new product designs?

A: Yes. The TSC-105D3H,000 carries active product status and ROHS3 compliance, making it appropriate for new designs requiring long-term component availability and regulatory compliance.

Q: What packaging options are available for substitute parts?

A: The HY1-5V is supplied in tube packaging. The TSC-105D3H,000 is also supplied in tube packaging. Both maintain through-hole PC pin termination compatible with standard PCB assembly processes.

Q: Are there any coil current or resistance considerations when substituting?

A: Yes. The HD1E-M-DC5V draws 56.1mA at 89 Ohms coil resistance. The HY1-5V draws 30mA at 166 Ohms, and the TSC-105D3H,000 draws 60mA at 83 Ohms. Circuit designs must accommodate these variations in coil current draw and impedance characteristics.

Q: What is the moisture sensitivity level for these relays?

A: All three parts—HD1E-M-DC5V, HY1-5V, and TSC-105D3H,000—carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
