MRPR-8-17-23 Equivalent & Substitute Parts

Part Overview

The MRPR-8-17-23 is a glass body reed switch manufactured by Littelfuse Inc., configured as a SPST-NO (Single Pole Single Throw - Normally Open) device. This through-hole component is rated for 700mA AC / 1A DC switching at 265V AC and 250V DC, with a 50W power rating. The device operates within a 17–23AT magnetic operate range and features 0.75ms operate time and 0.3ms release time.

The MRPR-8-17-23 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the MRPR-20-17-23 be used as a direct replacement for the MRPR-8-17-23 without circuit modifications?

A: Yes. The MRPR-20-17-23 maintains identical voltage ratings (265V AC / 250V DC), operate range (17–23AT), power rating (50W), mounting type (through hole), and physical dimensions. No circuit redesign is required.

Q: What is the primary difference between these two parts?

A: The MRPR-20-17-23 provides higher current-switching ratings (1.1A AC / 1.5A DC versus 700mA AC / 1A DC) and increased current-carry capacity (3A DC versus 2.5A DC). The MRPR-8-17-23 is obsolete; the MRPR-20-17-23 is active production.

Q: Are the physical dimensions identical?

A: Yes. Both components feature 2.230" overall length, 0.112" body diameter, and 0.800" body length. They are mechanically interchangeable in through-hole PCB applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MRPR-8-17-23 and MRPR-20-17-23 are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS codes (8536.50.9065).

Q: What is the operate range specification, and does it differ between the two parts?

A: Both parts operate within a 17–23AT magnetic operate range. This specification is identical and determines the magnetic field strength required to activate the switch.
