LP05-1A66-80V Reed Relay Equivalent & Substitute Parts

Part Overview

The LP05-1A66-80V is a through-hole mounted reed relay manufactured by Standex-Meder Electronics. This SPST-NO (1 Form A) relay is rated for 500 mA contact current at 5VDC coil voltage with a maximum switching voltage of 200VAC/200VDC. The product is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain functional compatibility across coil voltage, contact form, current rating, and switching voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP05-1A66-80V are selected based on strict electrical and mechanical compatibility criteria. All substitute candidates must satisfy the following mandatory parameters:

Primary Compatibility Criteria:

• Coil Voltage: 5VDC (exact match required)
• Contact Form: SPST-NO (1 Form A) (exact match required)
• Contact Rating: 500 mA (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)

Secondary Compatibility Criteria:

• Switching Voltage: Must equal or exceed 200VAC/200VDC maximum
• Operating Temperature Range: Must encompass or exceed -20°C ~ 70°C
• Coil Type: Non Latching (exact match required)

Three substitute parts from Coto Technology meet these criteria: 2204-05-411, 2904-05-411, and 2200-2301. All three are active products with current manufacturing status, providing long-term availability advantages over the obsolete LP05-1A66-80V.

Parameter Comparison

Engineering Selection Recommendations

2204-05-411 (Coto Technology)

The 2204-05-411 provides full electrical compatibility with the LP05-1A66-80V across all critical parameters: 5VDC coil voltage, SPST-NO contact form, 500 mA contact rating, and 200VAC/200VDC switching voltage. This part is active in production with ROHS3 compliance and hermetic sealing. The extended operating temperature range (-20°C ~ 85°C) exceeds the original specification. Lower coil current (13.5 mA vs. 21.7 mA) and higher coil resistance (370 Ohms vs. 230 Ohms) reduce power consumption. Faster switching times (0.5 ms operate, 0.1 ms release) improve circuit performance. This part is recommended for applications requiring maximum electrical equivalence and regulatory compliance.

2904-05-411 (Coto Technology)

The 2904-05-411 matches the LP05-1A66-80V in all primary electrical parameters: 5VDC coil voltage, SPST-NO contact form, 500 mA contact rating, and 200VAC/200VDC switching voltage. This part is active in production with ROHS3 compliance. The extended operating temperature range (-20°C ~ 85°C) exceeds the original specification. Coil current and resistance are identical to the 2204-05-411 (13.5 mA, 370 Ohms). Switching performance matches the 2204-05-411. Seal rating is not specified, distinguishing it from the hermetically sealed 2204-05-411. This part is suitable for applications where hermetic sealing is not required.

2200-2301 (Coto Technology)

The 2200-2301 satisfies all primary electrical compatibility criteria with the LP05-1A66-80V: 5VDC coil voltage, SPST-NO contact form, 500 mA contact rating, and through-hole PC pin termination. This part is active in production with hermetic sealing and extended operating temperature range (-20°C ~ 85°C). The maximum switching voltage is 150VAC/150VDC, which is lower than the original 200VAC/200VDC specification. Higher coil current (33.3 mA vs. 21.7 mA) and lower coil resistance (150 Ohms vs. 230 Ohms) increase power consumption. This part is suitable only for applications where the 150VAC/150VDC switching voltage limit is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 2200-2301 be used as a direct replacement for the LP05-1A66-80V?

A: The 2200-2301 is electrically compatible in coil voltage, contact form, and current rating. However, the maximum switching voltage is 150VAC/150VDC compared to the original 200VAC/200VDC. Use this part only if your application operates within the 150VAC/150VDC switching voltage limit.

Q: What is the primary difference between the 2204-05-411 and 2904-05-411?

A: Both parts have identical electrical specifications and switching performance. The 2204-05-411 includes hermetic sealing; the 2904-05-411 does not specify a seal rating. Select the 2204-05-411 for applications requiring environmental protection through hermetic sealing.

Q: Are all substitute parts RoHS compliant?

A: The 2204-05-411 and 2904-05-411 are ROHS3 compliant. The 2200-2301 RoHS status is not specified in the provided data. Verify RoHS compliance requirements with your procurement or regulatory team before final selection.

Q: Do the substitute parts have faster switching times than the original?

A: Yes. The 2204-05-411 and 2904-05-411 have operate times of 0.5 ms and release times of 0.1 ms, compared to the LP05-1A66-80V operate time of 0.7 ms and release time of 1.5 ms. The 2200-2301 has an operate time of 0.55 ms and release time of 0.1 ms. Faster switching may affect circuit timing; verify compatibility with your application.

Q: Which substitute part has the lowest power consumption?

A: The 2204-05-411 and 2904-05-411 both draw 13.5 mA coil current, compared to 21.7 mA for the LP05-1A66-80V. The 2200-2301 draws 33.3 mA, the highest among all options. Select the 2204-05-411 or 2904-05-411 for power-sensitive applications.

Q: What is the operating temperature advantage of the substitute parts?

A: All three substitute parts operate from -20°C to 85°C, extending the upper temperature limit by 15°C compared to the LP05-1A66-80V (-20°C to 70°C). This provides additional thermal margin for high-temperature environments.

Q: Are all parts available in the same packaging?

A: All substitute parts are supplied in tube packaging. Verify packaging requirements for your assembly process and procurement workflow.
