RGEF1400 Equivalent & Substitute Parts

Part Overview

The RGEF1400 is a polymeric PTC resettable fuse manufactured by Littelfuse Inc., designed for overcurrent protection in electronic circuits. This component operates at 16V maximum voltage with a 14A hold current rating and is housed in a through-hole radial disc package. The part maintains active product status with full compliance to ROHS3 and international safety certifications. Substitute parts are identified to provide equivalent functionality for applications requiring component availability, inventory optimization, or packaging format alternatives while maintaining identical electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RGEF1400 are classified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are: voltage rating (16V maximum), current hold rating (14A), current trip rating (23.8A), operating temperature range (-40°C to 85°C), mounting type (through hole), and package configuration (radial disc). All substitute parts must maintain identical electrical performance characteristics and comply with the same safety certifications.

RGEF1400-1 is classified as a direct manufacturer equivalent, sharing all electrical parameters and certifications with the main part while differing only in packaging format (bag versus bulk) and minimal dimensional variance in seated height (27.90mm versus 28.00mm).

16R1400GH is classified as a similar manufacturer part, maintaining all critical electrical parameters and certifications while representing an alternative product line (POLY-FUSE® 16R series versus PolySwitch® RGEF series). This part exhibits minor dimensional differences in width (4.60mm versus 2.90mm) and lead spacing (10.20mm versus 10.15mm), with packaging in bulk format and MSL rating of 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full ROHS3 compliance and international safety certifications. RGEF1400-1 is the primary direct substitute, offering identical electrical specifications and dimensional characteristics with only packaging format differentiation. This part is suitable for direct replacement in applications where the original RGEF1400 is specified.

16R1400GH serves as an alternative substitute from the POLY-FUSE® product line, maintaining all critical electrical parameters while introducing minor dimensional variations in width (4.60mm versus 2.90mm) and lead spacing (10.20mm versus 10.15mm). This part is suitable for applications where PCB layout accommodates the dimensional differences and where cURus certification meets regulatory requirements in place of UL certification.

Selection between RGEF1400-1 and 16R1400GH should be based on PCB design constraints, certification requirements specific to the application, and packaging format availability. Both parts provide equivalent overcurrent protection performance within the specified electrical operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RGEF1400-1 be used as a direct replacement for RGEF1400?

A: Yes. RGEF1400-1 maintains identical electrical specifications, operating temperature range, and safety certifications. Dimensional differences are negligible (seated height 27.90mm versus 28.00mm), and both parts use the same lead spacing (0.400" / 10.15mm). The primary difference is packaging format (bag versus bulk).

Q: What are the dimensional differences between RGEF1400 and 16R1400GH?

A: 16R1400GH exhibits width variation (4.60mm versus 2.90mm) and lead spacing variation (10.20mm versus 10.15mm). Seated height is identical (27.90mm). These differences require PCB layout verification before substitution.

Q: Are all three parts certified to the same standards?

A: RGEF1400 and RGEF1400-1 carry CSA, TUV, and UL certifications. 16R1400GH carries cURus and TUV certifications. Applications requiring UL certification must use RGEF1400 or RGEF1400-1.

Q: Do all substitute parts have the same electrical performance?

A: Yes. All three parts maintain identical voltage rating (16V), current hold rating (14A), current trip rating (23.8A), time to trip (9s), and resistance characteristics (Ri 2.6 mOhms minimum, R1 6.4 mOhms maximum).

Q: What is the inventory status of each part?

A: RGEF1400 has 772 pieces in stock (bag packaging). RGEF1400-1 has 1206 pieces in stock (bag packaging). 16R1400GH has 12083 pieces in stock (bulk packaging).
